-# 快速开始
-## 作为全局模块
-### 安装
-
-对于Debian或者Ubuntu系统,在安装AnyProxy之前,可能还需要安装 `nodejs-legacy`
-
-```bash
-sudo apt-get install nodejs-legacy
-```
-
-然后,安装AnyProxy
-
-```bash
-npm install -g anyproxy@beta #本文档对应的AnyProxy为4.0Beta版
-```
-
-### 启动
-
-* 命令行启动AnyProxy,默认端口号8001
-
-```bash
-anyproxy
-```
-
-* 启动后将终端http代理服务器配置为127.0.0.1:8001即可
-* 访问http://127.0.0.1:8002 ,web界面上能看到所有的请求信息
-
-### 其他命令
-
-* 配置启动端口,如1080端口启动
-
-```bash
-anyproxy --port 1080
-```
-
-## 作为npm模块使用
-
-AnyProxy可以作为一个npm模块使用,整合进其他工具。
-
-> 如要启用https解析,请在代理服务器启动前自行调用`AnyProxy.utils.certMgr`相关方法生成证书,并引导用户信任安装。或引导用户使用`anyproxy-ca`方法。
-
-* 引入
-
-```bash
-npm i anyproxy@beta --save # 4.0版正在beta中
-```
-
-* 使用举例
-
-```js
-const AnyProxy = require('anyproxy');
-const options = {
-  port: 8001,
-  rule: require('myRuleModule'),
-  webInterface: {
-    enable: true,
-    webPort: 8002,
-    wsPort: 8003,
-  },
-  throttle: 10000,
-  forceProxyHttps: false,
-  silent: false
-};
-const proxyServer = new AnyProxy.ProxyServer(options);
-
-proxyServer.on('ready', () => { /* */ });
-proxyServer.on('error', (e) => { /* */ });
-proxyServer.start();
-
-//when finished
-proxyServer.close();
-```
-
-* Class: AnyProxy.proxyServer
-  * 创建代理服务器
-
-    ```js
-    const proxy = new AnyProxy.proxyServer(options)
-    ```
-
-  * `options`
-    * `port` {number} 必选,代理服务器端口
-    * `rule` {object} 自定义规则模块
-    * `throttle` {number} 限速值,单位kb/s,默认不限速
-    * `forceProxyHttps` {boolean} 是否强制拦截所有的https,忽略规则模块的返回,默认`false`
-    * `silent` {boolean} 是否屏蔽所有console输出,默认`false`
-    * `dangerouslyIgnoreUnauthorized` {boolean} 是否忽略请求中的证书错误,默认`false`
-    * `webInterface` {object} web版界面配置
-      * `enable` {boolean} 是否启用web版界面,默认`false`
-      * `webPort` {number} web版界面端口号,默认`8002`
-  * Event: `ready`
-    * 代理服务器启动完成
-    * 示例
-
-    ```js
-    proxy.on('ready', function() { })
-    ```
-
-  * Event: `error`
-    * 代理服务器发生错误
-    * 示例
-
-    ```js
-    proxy.on('error', function() { })
-    ```
-  * Method: `start`
-    * 启动代理服务器
-    * 示例
-
-    ```js
-    proxy.start();
-    ```
-  * Method: `close`
-    * 关闭代理服务器
-    * 示例
-
-    ```js
-    proxy.close();
-    ```
-* AnyProxy.utils.systemProxyMgr
-  * 管理系统的全局代理配置,方法调用时可能会弹出密码框
-  * 使用示例
-
-  ```js
-  // 配置127.0.0.1:8001为全局http代理服务器
-  AnyProxy.utils.systemProxyMgr.enableGlobalProxy('127.0.0.1', '8001');
-
-  // 关闭全局代理服务器
-  AnyProxy.utils.systemProxyMgr.disableGlobalProxy();
-  ```
-
-* AnyProxy.utils.certMgr
-  * 管理AnyProxy的证书
-  * `AnyProxy.utils.certMgr.ifRootCAFileExists()`
-    * 校验系统内是否存在AnyProxy的根证书
-  * `AnyProxy.utils.certMgr.generateRootCA(callback)`
-    * 生成AnyProxy的rootCA,完成后请引导用户信任.crt文件
-  * 样例
-
-  ```js
-    const AnyProxy = require('AnyProxy');
-    const exec = require('child_process').exec;
-
-    if (!AnyProxy.utils.certMgr.ifRootCAFileExists()) {
-      AnyProxy.utils.certMgr.generateRootCA((error, keyPath) => {
-        // let users to trust this CA before using proxy
-        if (!error) {
-          const certDir = require('path').dirname(keyPath);
-          console.log('The cert is generated at', certDir);
-          const isWin = /^win/.test(process.platform);
-          if (isWin) {
-            exec('start .', { cwd: certDir });
-          } else {
-            exec('open .', { cwd: certDir });
-          }
-        } else {
-          console.error('error when generating rootCA', error);
-        }
-      });
-    }
-  ```
-
-# 代理HTTPS
-* AnyProxy默认不对https请求做处理,如需看到明文信息,需要配置CA证书
-
-> 解析https请求的原理是中间人攻击(man-in-the-middle),用户必须信任AnyProxy生成的CA证书,才能进行后续流程
-
-* 生成证书并解析所有https请求
-
-```bash
-anyproxy-ca #生成rootCA证书,生成后需要手动信任
-anyproxy --intercept #启动AnyProxy,并解析所有https请求
-```
-
-* [附录:如何信任CA证书](#证书配置)
-
-# rule模块
-
-AnyProxy提供了二次开发的能力,你可以用js编写自己的规则模块(rule),来自定义网络请求的处理逻辑。
-
->注意:引用规则前,请务必确保文件来源可靠,以免发生安全问题
-
-规则模块的能力范围包括:
-
-* 拦截并修改正在发送的请求
-  * 可修改内容包括请求头(request header),请求体(request body),甚至是请求的目标地址等
-* 拦截并修改服务端响应
-  * 可修改的内容包括http状态码(status code)、响应头(response header)、响应内容等
-* 拦截https请求,对内容做修改
-  * 本质是中间人攻击(man-in-the-middle attack),需要客户端提前信任AnyProxy生成的CA
-
-### 开发示例
-
-* 举例
-  * 需要编写一个规则模块,在 GET http://httpbin.org/user-agent 的返回值里加上测试信息,并延迟5秒返回
-
-* Step 1,编写规则
-
-  ```js
-  // file: sample.js
-  module.exports = {
-    summary: 'a rule to modify response',
-    *beforeSendResponse(requestDetail, responseDetail) {
-      if (requestDetail.url === 'http://httpbin.org/user-agent') {
-        const newResponse = responseDetail.response;
-        newResponse.body += '-- AnyProxy Hacked! --';
-        return new Promise((resolve, reject) => {
-          setTimeout(() => { // delay
-            resolve({ response: newResponse });
-          }, 5000);
-        });
-      }
-    },
-  };
-  ```
-
-* Step 2, 启动AnyProxy,加载规则
-  * 运行 `anyproxy --rule sample.js`
-
-* Step 3, 测试规则
-
-  * 用curl测试
-    ```bash
-    curl http://httpbin.org/user-agent --proxy http://127.0.0.1:8001
-    ```
-
-  * 用浏览器测试:配置浏览器http代理为 127.0.0.1:8001,访问 http://httpbin.org/user-agent
-
-  * 经过代理服务器后,期望的返回如下
-
-  ```
-  {
-    "user-agent": "curl/7.43.0"
-  }
-  - AnyProxy Hacked!
-  ```
-
-* Step 4, 查看请求信息
-
-  * 浏览器访问http://127.0.0.1:8002 ,界面上能看到刚才的请求信息
-
-### 处理流程
-
-* 处理流程图如下
-
-<img src="https://zos.alipayobjects.com/rmsportal/TWyNuSJtEZBdrdcOMRjE.png" width="550" />
-
-* 当http请求经过代理服务器时,具体处理过程是:
-  * 收集请求所有请求参数,包括method, header, body等
-  * AnyProxy调用规则模块`beforeSendRequest`方法,由模块做处理,返回新的请求参数,或返回响应内容
-  * 如果`beforeSendRequest`返回了响应内容,则立即把此响应返回到客户端(而不再发送到真正的服务端),流程结束。
-  * 根据请求参数,向服务端发出请求,接收服务端响应。
-  * 调用规则模块`beforeSendResponse`方法,由模块对响应内容进行处理
-  * 把响应信息返回给客户端
-
-* 当代理服务器收到https请求时,AnyProxy可以替换证书,对请求做明文解析。
-  * 调用规则模块`beforeDealHttpsRequest`方法,如果返回`true`,会明文解析这个请求,其他请求不处理
-  * 被明文解析后的https请求,处理流程同http一致。未明文解析请求不会再进入规则模块做处理。
-
-
-### 如何引用
-
-如下几种方案都可以用来引用规则模块:
-
-* 使用本地路径
-```bash
-anyproxy --rule ./rule.js
-```
-* 使用在线地址
-```bash
-anyproxy --rule https://sample.com/rule.js
-```
-
-* 使用npm包
-  * AnyProxy使用`require()`加载本地规则,你可以在参数里传入一个本地的npm包路径,或是某个全局安装的npm包
-
-  ```bash
-anyproxy --rule ./myRulePkg/ #本地包
-npm i -g myRulePkg && anyproxy --rule myRulePkg #全局包
-  ```
-
-
-# rule接口文档
-
-规则模块应该符合cmd规范,一个典型的规则模块代码结构如下。模块中所有方法都是可选的,只需实现业务感兴趣的部分即可。
-
-```js
-module.exports = {
-  // 模块介绍
-  summary: 'my customized rule for AnyProxy',
-  // 发送请求前拦截处理
-  *beforeSendRequest(requestDetail) { /* ... */ },
-  // 发送响应前处理
-  *beforeSendResponse(requestDetail, responseDetail) { /* ... */ },
-  // 是否处理https请求
-  *beforeDealHttpsRequest(requestDetail) { /* ... */ },
-  // 请求出错的事件
-  *onError(requestDetail, error) { /* ... */ },
-  // https连接服务器出错
-  *onConnectError(requestDetail, error) { /* ... */ }
-};
-```
-
-> 规则文件中,除了summary,都是由 [co](https://www.npmjs.com/package/co) 驱动的,函数需要满足yieldable。可以返回promise或使用generator函数。
-
-### summary
-
-#### summary(): string | summary:string
-
-* 规则模块的介绍文案,用于AnyProxy提示用户, 可以是一个函数,也可以是一个普通的字符串
-
-### beforeSendRequest
-#### beforeSendRequest(requestDetail)
-
-* AnyProxy向服务端发送请求前,会调用`beforeSendRequest`,并带上参数`requestDetail`
-* `requestDetail`
-  * `protocol` {string} 请求使用的协议,http或者https
-  * `requestOptions` {object} 即将发送的请求配置,供require('http').request作为使用。详见:https://nodejs.org/api/http.html#http_http_request_options_callback
-  * `requestData` {object} 请求Body
-  * `url` {string} 请求url
-  * `_req` {object} 请求的原始request
-* 举例:请求 *anyproxy.io* 时,`requestDetail`参数内容大致如下
-
-  ```js
-  {
-    protocol: 'http',
-    url: 'http://anyproxy.io/',
-    requestOptions: {
-      hostname: 'anyproxy.io',
-      port: 80,
-      path: '/',
-      method: 'GET',
-      headers: {
-        Host: 'anyproxy.io',
-        'Proxy-Connection': 'keep-alive',
-        'User-Agent': '...'
-      }
-    },
-    requestData: '...',
-    _req: { /* ... */}
-  }
-  ```
-
-* 以下几种返回都是合法的
-  * 不做任何处理,返回null
-
-  ```js
-  return null;
-  ```
-
-  * 修改请求协议,如强制改用https发起请求
-
-  ```js
-  return {
-    protocol: 'https'
-  };
-  ```
-
-  * 修改请求参数
-
-  ```js
-  var newOption = Object.assign({}, requestDetail.requestOptions);
-  newOption.path = '/redirect/to/another/path';
-  return {
-    requestOptions: newOption
-  };
-  ```
-  * 修改请求body
-
-  ```js
-  return {
-    requestData: 'my new request data'
-    //这里也可以同时加上requestOptions
-  };
-  ```
-  * 直接返回客户端,不再发起请求,其中`statusCode` `header` 是必选字段
-
-  ```js
-  return {
-    response: {
-      statusCode: 200,
-      header: { 'content-type': 'text/html' },
-      body: 'this could be a <string> or <buffer>'
-    }
-  };
-  ```
-
-### beforeSendResponse
-
-#### beforeSendResponse(requestDetail, responseDetail)
-
-* AnyProxy向客户端发送请求前,会调用`beforeSendResponse`,并带上参数`requestDetail` `responseDetail`
-* `requestDetail` 同`beforeSendRequest`中的参数
-* `responseDetail`
-  * `response` {object} 服务端的返回信息,包括`statusCode` `header` `body`三个字段
-  * `_res` {object} 原始的服务端返回对象
-* 举例,请求 *anyproxy.io* 时,`responseDetail`参数内容大致如下
-
-  ```js
-  {
-    response: {
-      statusCode: 200,
-      header: {
-        'Content-Type': 'image/gif',
-        Connection: 'close',
-        'Cache-Control': '...'
-      },
-      body: '...'
-    },
-    _res: { /* ... */ }
-  }
-  ```
-
-* 以下几种返回都是合法的
-  * 不做任何处理,返回null
-
-  ```js
-  return null;
-  ```
-
-  * 修改返回的状态码
-
-  ```js
-  var newResponse = Object.assign({}, responseDetail.response);
-  newResponse.statusCode = 404;
-  return {
-    response: newResponse
-  };
-  ```
-
-  * 修改返回的内容
-
-  ```js
-  var newResponse = Object.assign({}, responseDetail.response);
-  newResponse.body += '--from anyproxy--';
-  return {
-    response: newResponse
-  };
-  ```
-
-### beforeDealHttpsRequest
-
-#### beforeDealHttpsRequest(requestDetail)
-
-* AnyProxy收到https请求时,会调用`beforeDealHttpsRequest`,并带上参数`requestDetail`
-* 如果配置了全局解析https的参数,则AnyProxy会略过这个调用
-* 只有返回`true`时,AnyProxy才会尝试替换证书、解析https。否则只做数据流转发,无法看到明文数据。
-* 注意:https over http的代理模式中,这里的request是CONNECT请求
-* `requestDetail`
-  * `host` {string} 请求目标的Host,受制于协议,这里无法获取完整url
-  * `_req` {object} 请求的原始request
-* 返回值
-  * `true`或者`false`,表示是否需要AnyProxy替换证书并解析https
-
-### onError
-
-#### onError(requestDetail, error)
-
-* 在请求处理过程中发生错误时,AnyProxy会调用`onError`方法,并提供对应的错误信息
-* 多数场景下,错误会在请求目标服务器的时候发生,比如DNS解析失败、请求超时等
-* `requestDetail` 同`beforeSendRequest`中的参数
-* 以下几种返回都是合法的
-  * 不做任何处理。此时AnyProxy会返回一个默认的错误页。
-
-  ```js
-  return null;
-  ```
-
-  * 返回自定义错误页
-
-  ```js
-  return {
-    response: {
-      statusCode: 200,
-      header: { 'content-type': 'text/html' },
-      body: 'this could be a <string> or <buffer>'
-    }
-  };
-  ```
-
-### onConnectError
-
-#### onConnectError(requestDetail, error)
-
-* AnyProxy在与目标HTTPS服务器建立连接的过程中,如果发生错误,AnyProxy会调用这个方法
-* `requestDetail` 同`beforeDealHttpsRequest`中的参数
-* 此处无法控制向客户端的返回信息,无需返回值。
-
-# rule样例
-
-* 这里提供一些样例,来讲解规则模块的常见用法
-* 你可以通过 `anyproxy --rule http://....js` 来加载模块并体验
-* 用curl发请求测试的方法如下
-  * 直接请求服务器:`curl http://httpbin.org/`
-  * 通过代理服务器请求:`curl http://httpbin.org/ --proxy http://127.0.0.1:8001`
-
-### 使用本地数据
-  * 拦截发送到 http://httpbin.org 的请求,使用本地数据代替服务端返回
-
-```bash
-anyproxy --rule rule_sample/sample_use_local_response.js
-```
-```js
-/* 
-  sample: 
-    intercept all requests toward httpbin.org, use a local response
-  test:
-    curl http://httpbin.org/user-agent --proxy http://127.0.0.1:8001
-*/
-module.exports = {
-  *beforeSendRequest(requestDetail) {
-    const localResponse = {
-      statusCode: 200,
-      header: { 'Content-Type': 'application/json' },
-      body: '{"hello": "this is local response"}'
-    };
-    if (requestDetail.url.indexOf('http://httpbin.org') === 0) {
-      return {
-        response: localResponse
-      };
-    }
-  },
-};
-
-```
-
-### 修改请求头
-  * 修改发送到 httpbin.org 的user-agent
-
-```bash
-anyproxy --rule rule_sample/sample_modify_request_header.js
-```
-```js
-/* 
-  sample: 
-    modify the user-agent in requests toward httpbin.org
-  test:
-    curl http://httpbin.org/user-agent --proxy http://127.0.0.1:8001
-*/
-module.exports = {
-  *beforeSendRequest(requestDetail) {
-    if (requestDetail.url.indexOf('http://httpbin.org') === 0) {
-      const newRequestOptions = requestDetail.requestOptions;
-      newRequestOptions.headers['User-Agent'] = 'AnyProxy/0.0.0';
-      return {
-        requestOptions: newRequestOptions
-      };
-    }
-  },
-};
-
-```
-
-### 修改请求数据
-  * 修改发送到 http://httpbin.org/post 的post数据
-
-```bash
-anyproxy --rule rule_sample/sample_modify_request_data.js
-```
-```js
-/*
-  sample:
-    modify the post data towards http://httpbin.org/post
-  test:
-    curl -H "Content-Type: text/plain" -X POST -d 'original post data' http://httpbin.org/post --proxy http://127.0.0.1:8001
-  expected response:
-    { "data": "i-am-anyproxy-modified-post-data" }
-*/
-module.exports = {
-  summary: 'Rule to modify request data',
-  *beforeSendRequest(requestDetail) {
-    if (requestDetail.url.indexOf('http://httpbin.org/post') === 0) {
-      return {
-        requestData: 'i-am-anyproxy-modified-post-data'
-      };
-    }
-  },
-};
-
-```
-
-### 修改请求的目标地址
-  * 把所有发送到 http://httpbin.org/ 的请求全部改到 http://httpbin.org/user-agent
-
-```bash
-anyproxy --rule rule_sample/sample_modify_request_path.js
-```
-```js
-/* 
-  sample: 
-    redirect all httpbin.org requests to http://httpbin.org/user-agent
-  test:
-    curl http://httpbin.org/any-path --proxy http://127.0.0.1:8001
-  expected response:
-    { "user-agent": "curl/7.43.0" }
-*/
-module.exports = {
-  *beforeSendRequest(requestDetail) {
-    if (requestDetail.url.indexOf('http://httpbin.org') === 0) {
-      const newRequestOptions = requestDetail.requestOptions;
-      newRequestOptions.path = '/user-agent';
-      newRequestOptions.method = 'GET';
-      return {
-        requestOptions: newRequestOptions
-      };
-    }
-  },
-};
-
-```
-
-### 修改请求协议
-  * 把用http协议请求的 http://httpbin.org 改成https并发送
-
-```bash
-anyproxy --rule rule_sample/sample_modify_request_protocol.js
-```
-```js
-/* 
-  sample: 
-    redirect all http requests of httpbin.org to https
-  test:
-    curl 'http://httpbin.org/get?show_env=1' --proxy http://127.0.0.1:8001
-  expected response:
-    { "X-Forwarded-Protocol": "https" }
-*/
-module.exports = {
-  *beforeSendRequest(requestDetail) {
-    if (requestDetail.url.indexOf('http://httpbin.org') === 0) {
-      const newOption = requestDetail.requestOptions;
-      newOption.port = 443;
-      return {
-        protocol: 'https',
-        requestOptions: newOption
-      };
-    }
-  }
-};
-
-```
-
-### 修改返回状态码
-  * 把 所有http://httpbin.org 的返回状态码都改成404
-
-```bash
-anyproxy --rule rule_sample/sample_modify_response_statuscode.js
-```
-```js
-/* 
-  sample: 
-    modify all status code of http://httpbin.org/ to 404
-  test:
-    curl -I 'http://httpbin.org/user-agent' --proxy http://127.0.0.1:8001
-  expected response:
-    HTTP/1.1 404 Not Found
-*/

-# 证书配置
-
-### OSX系统信任CA证书
-
-* 类似这种报错都是因为系统没有信任AnyProxy生成的CA所造成的

-# FAQ
-
-#### Q: 为什么https请求不能进入处理函数?
- A: 以下任意一项都能用来改变https的处理特性:
-     1. 命令行启动AnyProxy时配置`--intercept`参数,按npm模块启动时配置`forceProxyHttps`参数,所有Https请求都会被替换证书并解析
-     2. 规则文件内提供`beforeDealHttpsRequest`方法,返回 *true* 的https请求会被解析
-
-#### Q: 提示 *function is not yieldable*
- * A: 规则模块是用 [co](https://www.npmjs.com/package/co) 驱动的,函数需要满足yieldable。可以使用generator方法或是返回Promise。
-
-#### Q: The connection is not private
-当访问特定的HTTPS站点,AnyProxy会提示该站点不是一个安全的网站,这通常是因为站点的证书设置不能被正确识别导致的(比如,站点的证书是自签发的)。如果您信任该网站,可以用以下方式来继续访问:
-- 命令行直接启动
-
-  通过启动参数 `--ignore-unauthorized-ssl` 来忽略证书认证的错误。需要注意的是,该参数是全局生效的,如果你在此期间访问了其他未知的网站,他们的证书问题也会被忽略,这可能会带来安全隐患。
-
-  ```bash
-  anyproxy -i --ignore-unauthorized-ssl
-  ```
-
-- 在Nodejs代码中启动
-
-  在构造AnyProxy实例的时候,传入参数`dangerouslyIgnoreUnauthorized:true`, 如下:
-
-  ```js
-   const options = {
-    ...,
-    dangerouslyIgnoreUnauthorized: true
-   };
-
-   const anyproxyIns = new AnyProxy.ProxyCore(options);
-   anyproxyIns.start();
-  ```
-
-  *通过这种方式初始化的AnyProxy,其配置也是全局性的,所有网站的证书问题都会被忽略*
-
-- 通过自定义的Rule来修改
-
-  我们自然也可以借助自定义的Rule来实现这个效果,而且我们还可以控制到只允许指定网址的证书错误,对不在列表的网址,进行证书的强验证。
-
-  ```js
-  module.exports = {
-    *beforeSendRequest(requestDetail) {
-      if (requestDetail.url.indexOf('https://the-site-you-know.com') === 0) {
-        const newRequestOptions = requestDetail.requestOptions;
-        // 设置属性 rejectUnauthorized 为 false
-        newRequestOptions.rejectUnauthorized = false;
-        return {
-          requestOptions: newRequestOptions
-        };
-      }
-    },
-  };
-  ```

-
-# Proxy Https
-
-* AnyProxy does NOT intercept https requests by default. To view decrypted info, you have to config the CA certificate.
-
-> Under the hood, AnyProxy decryptes https requests by man-in-the-middle attack. Users have to trust the CA cert in advance. Otherwise, client side will issue errors about unsecure network.
-
-* generate certifycates and intercept
-
-```bash
-anyproxy-ca #generate root CA. manually trust it after that.
-anyproxy --intercept #launch anyproxy and intercept all https traffic
-```
-
-* [Appendix:how to trust CA](#config-certification)
-
-# Rule Introduction
-
-AnyProxy provides the ability to load your own rules written in javascript. With rule module, you could customize the logic to handle requests.
-
-> Make sure your rule file is got from a trusted source. Otherwise, you may face some unknown security risk.
-
-Rule module could do the following stuff:
-* intercept and modify the request which is being sent
-  * editable fields include request header, body, target address
-* intercept and modify the response from server
-  * editable fields include response status code, header, body
-* intercept https requests, modify request and response
-
-### sample
-
-* Target
-  * write a rule module to append some text to the response of GET http://httpbin.org/user-agent, and delay the response for 5 seconds
-
-* Step 1,Write the rule file, save as sample.js
-
-  ```js
-  // file: sample.js
-  module.exports = {
-    summary: 'a rule to modify response',
-    *beforeSendResponse(requestDetail, responseDetail) {
-      if (requestDetail.url === 'http://httpbin.org/user-agent') {
-        const newResponse = responseDetail.response;
-        newResponse.body += '-- AnyProxy Hacked! --';
-        return new Promise((resolve, reject) => {
-          setTimeout(() => { // delay
-            resolve({ response: newResponse });
-          }, 5000);
-        });
-      }
-    },
-  };
-  ```
-
-* Step 2, start AnyProxy and load the rule file
-  * run `anyproxy --rule sample.js`
-
-* Step 3, test
-
-  * use curl
-    ```bash
-    curl http://httpbin.org/user-agent --proxy http://127.0.0.1:8001
-    ```
-
-  * use browser. Point the http proxy of browser to 127.0.0.1:8001, then visit http://httpbin.org/user-agent
-
-  * the expected response from proxy is
-
-  ```
-  {
-    "user-agent": "curl/7.43.0"
-  }
-  - AnyProxy Hacked!
-  ```
-
-* Step 4, view the request log
-
-  * visit http://127.0.0.1:8002, the request just sent should be listed here
-
-### how does it work
-
-* The flow chart is as follows
-
-<img src="https://zos.alipayobjects.com/rmsportal/TWyNuSJtEZBdrdcOMRjE.png" width="550" />
-
-* When got an http request, the entire process of proxy server is
-  * AnyProxy collects all the quest info, include method, header, body
-  * AnyProxy calls `beforeSendRequest` of the rule module. Rule module deal the request, return new request param or response content
-  * If `beforeSendRequest` returns the response content, AnyProxy will send the response to client without sending to target server. The process ends here.
-  * Send request to target server, collect response
-  * Call `beforeSendResponse` of the rule module. Rule module deal the response data
-  * Send response to client
-
-* When AnyProxy get https request, it could replace the certificate and decrypt the request data
-  * AnyProxy calls `beforeDealHttpsRequest` of the rule module
-  * If the function returns `true`, AnyProxy will do the man-in-the-middle attack to it. Otherwise, the request will not be dealed.
-
-### how to load rule module
-
-* use local file
-```bash
-anyproxy --rule ./rule.js
-```
-
-* use an online rule file
-```bash
-anyproxy --rule https://sample.com/rule.js
-```
-
-* use an npm module
-  * AnyProxy uses `require()` to load rule module. You could either load a local npm module or a global-installed one.
-
-  ```bash
-anyproxy --rule ./myRulePkg/ #local module
-npm i -g myRulePkg && anyproxy --rule myRulePkg #global-installed module
-  ```
-
-# Rule module interface
-
-A typical rule module is as follows. All the functions are optional, just write the part you are interested in.
-
-```js
-module.exports = {
-  // introduction
-  summary: 'my customized rule for AnyProxy',
-  // intercept before send request to server
-  *beforeSendRequest(requestDetail) { /* ... */ },
-  // deal response before send to client
-  *beforeSendResponse(requestDetail, responseDetail) { /* ... */ },
-  // if deal https request
-  *beforeDealHttpsRequest(requestDetail) { /* ... */ },
-  // error happened when dealing requests
-  *onError(requestDetail, error) { /* ... */ },
-  // error happened when connect to https server
-  *onConnectError(requestDetail, error) { /* ... */ }
-};
-```
-
-> All functions in your rule file, except summary, are all driven by [co](https://www.npmjs.com/package/co) . They should be yieldable, i.e. return a promise or be a generator function.
-
-### summary
-
-#### summary
-
-* Introduction of this rule file. AnyProxy will read this field and give some tip to user.
-
-### beforeSendRequest
-#### beforeSendRequest(requestDetail)
-
-* Before sending request to server, AnyProxy will call `beforeSendRequest` with param `requestDetail`
-* `requestDetail`
-  * `protocol` {string} the protocol to use, http or https
-  * `requestOptions` {object} the options of the request-to-go, a param of require('http').request . ref: https://nodejs.org/api/http.html#http_http_request_options_callback
-  * `requestData` {object} request body
-  * `url` {string} request url
-  * `_req` {object} the native node.js request object
-* e.g. When requesting  *anyproxy.io*, `requestDetail` is something like the following

-    url: 'http://anyproxy.io/',
-    requestOptions: {
-      hostname: 'anyproxy.io',
-      port: 80,
-      path: '/',
-      method: 'GET',
-      headers: {
-        Host: 'anyproxy.io',
-        'Proxy-Connection': 'keep-alive',
-        'User-Agent': '...'
-      }
-    },
-    requestData: '...',
-    _req: { /* ... */}
-  }
-  ```
-
-* Any of these return values are valid
-  * do nothing, and return null
-
-  ```js
-  return null;
-  ```
-
-  * modify the request protocol,i.e. force use https
-
-  ```js
-  return {
-    protocol: 'https'
-  };
-  ```
-
-  * modify request param
-
-  ```js
-  var newOption = Object.assign({}, requestDetail.requestOptions);
-  newOption.path = '/redirect/to/another/path';
-  return {
-    requestOptions: newOption
-  };
-  ```
-  * modify request body
-
-  ```js
-  return {
-    requestData: 'my new request data'
-    // requestOptions can also be used here
-  };
-  ```
-  * give response to the client, not sending request any longer. `statusCode` `headers`are required is this situation.
-
-  ```js
-  return {
-    response: {
-      statusCode: 200,
-      header: { 'content-type': 'text/html' },

-    }
-  };
-  ```
-
-### beforeSendResponse
-
-#### beforeSendResponse(requestDetail, responseDetail)

-* `responseDetail`
-  * `response` {object} the response from server, includes `statusCode` `header` `body`
-  * `_res` {object} the native node.js response object
-* e.g. When requesting *anyproxy.io*, `responseDetail` is something like the following

-      },
-      body: '...'
-    },
-    _res: { /* ... */ }
-  }
-  ```
-* Any of these return values are valid
-  * do nothing, and return null
-
-  ```js
-  return null;
-  ```
-
-  * modify the response status code
-
-  ```js
-  var newResponse = Object.assign({}, responseDetail.response);
-  newResponse.statusCode = 404;
-  return {
-    response: newResponse
-  };
-  ```
-
-  * modify the response content
-
-  ```js
-  var newResponse = Object.assign({}, responseDetail.response);
-  newResponse.body += '--from anyproxy--';
-  return {
-    response: newResponse
-  };
-  ```
-
-### beforeDealHttpsRequest
-
-#### beforeDealHttpsRequest(requestDetail)
-
-* When receiving https request, AnyProxy will call `beforeDealHttpsRequest` with param `requestDetail`
-* If configed with `forceProxyHttps` in launching, AnyProxy will skip calling this method
-* Only by returning true, AnyProxy will try to replace the certificate and intercept the https request.
-* `requestDetail`
-  * `host` {string} the target host to request. Due to the request protocol, full url couldn't be got here
-  * `_req` {object} the native node.js request object. The `_req` here refers to the CONNECT request.
-* return value
-  * `true` or `false`, whether AnyProxy should intercept the https request
-
-### onError
-
-#### onError(requestDetail, error)
-
-* AnyProxy will call this method when an error happened in request handling.
-* Errors usually are issued during requesting, e.g. DNS failure, request timeout
-* `requestDetail` is the same one as in `beforeSendRequest`
-* Any of these return values are valid
-  * do nothing, and AnyProxy will response a default error page
-
-  ```js
-  return null;
-  ```
-
-  * return a customized error page
-
-  ```js
-  return {
-    response: {
-      statusCode: 200,

-### onConnectError
-
-#### onConnectError(requestDetail, error)
-
-* AnyProxy will call this method when failed to connect target server in https request
-* `requestDetail` is the same one as in `beforeDealHttpsRequest`
-* no return value is required

-# FAQ
-
-
-### Q: can not deal https request in rule module.
- * A: Any of these options could be used to change the way AnyProxy deall https requests
-     1. config `--intercept` when luanching AnyProxy via cli, or use `forceProxyHttps` when using as an npm module
-     2. place a `beforeDealHttpsRequest` function in your rule file and determine which request to intercept by your own.
-
-### Q: get an error says *function is not yieldable*
- * A: Rule module is driven by [co](https://www.npmjs.com/package/co). The functions inside should  be yieldable, i.e. return a promise or be a generator function.
-
-### Q: The connection is not private
-AnyProxy will propmt this message when the certification of the site you're visiting is not issued by a common known CA. This happens when the certification is self-signed. If you know and trust it, you can ignore the error as below.
-
-- If you run AnyProxy by command line
-  Pass in the option `--ignore-unauthorized-ssl` to ignore the certification errors, please mind that the option will be active for all connections.
-
-  ```bash
-  anyproxy -i --ignore-unauthorized-ssl
-  ```
-- If you run AnyProxy by Nodejs
-  Pass in the option `dangerouslyIgnoreUnauthorized:true`, like this:
-
-  ```js
-  const options = {
-   ...,
-   dangerouslyIgnoreUnauthorized: true
-  };
-
-  const anyproxyIns = new AnyProxy.ProxyCore(options);
-  anyproxyIns.start();
-  ```
-
-  *This is also a global option, all certification errors will be ignored*
-
-- With the help of AnyProxy Rule
-  You can change the request with rule of course. For this scenario, all you need is to pass in an option to Nodejs `Http.rquest`, as we do in AnyProxy. A simple demo below:
-
-  ```js
-  module.exports = {
-    *beforeSendRequest(requestDetail) {
-      if (requestDetail.url.indexOf('https://the-site-you-know.com') === 0) {
-        const newRequestOptions = requestDetail.requestOptions;
-        // set rejectUnauthorized as false
-        newRequestOptions.rejectUnauthorized = false;
-        return {
-          requestOptions: newRequestOptions
-        };
-      }
-    },
-  };
-  ```
-
-  And we get a bonous here, AnyProxy will only ignore the errors for the site(s) we want it to!

-# 快速开始
-## 作为全局模块
-### 安装
-
-对于Debian或者Ubuntu系统,在安装AnyProxy之前,可能还需要安装 `nodejs-legacy`
-
-```bash
-sudo apt-get install nodejs-legacy
-```
-
-然后,安装AnyProxy
-
-```bash
-npm install -g anyproxy@beta #本文档对应的AnyProxy为4.0Beta版
-```
-
-### 启动
-
-* 命令行启动AnyProxy,默认端口号8001
-
-```bash
-anyproxy
-```
-
-* 启动后将终端http代理服务器配置为127.0.0.1:8001即可
-* 访问http://127.0.0.1:8002 ,web界面上能看到所有的请求信息
-
-### 其他命令
-
-* 配置启动端口,如1080端口启动
-
-```bash
-anyproxy --port 1080
-```
-
-## 作为npm模块使用
-
-AnyProxy可以作为一个npm模块使用,整合进其他工具。
-
-> 如要启用https解析,请在代理服务器启动前自行调用`AnyProxy.utils.certMgr`相关方法生成证书,并引导用户信任安装。或引导用户使用`anyproxy-ca`方法。
-
-* 引入
-
-```bash
-npm i anyproxy@beta --save # 4.0版正在beta中
-```
-
-* 使用举例
-
-```js
-const AnyProxy = require('anyproxy');
-const options = {
-  port: 8001,
-  rule: require('myRuleModule'),
-  webInterface: {
-    enable: true,
-    webPort: 8002,
-    wsPort: 8003,
-  },
-  throttle: 10000,
-  forceProxyHttps: false,
-  silent: false
-};
-const proxyServer = new AnyProxy.ProxyServer(options);
-
-proxyServer.on('ready', () => { /* */ });
-proxyServer.on('error', (e) => { /* */ });
-proxyServer.start();
-
-//when finished
-proxyServer.close();
-```
-
-* Class: AnyProxy.proxyServer

-    * `dangerouslyIgnoreUnauthorized` {boolean} 是否忽略请求中的证书错误,默认`false`
-    * `webInterface` {object} web版界面配置
-      * `enable` {boolean} 是否启用web版界面,默认`false`
-      * `webPort` {number} web版界面端口号,默认`8002`
-  * Event: `ready`
-    * 代理服务器启动完成
-    * 示例
-
-    ```js
-    proxy.on('ready', function() { })
-    ```
-
-  * Event: `error`
-    * 代理服务器发生错误
-    * 示例
-
-    ```js
-    proxy.on('error', function() { })
-    ```
-  * Method: `start`
-    * 启动代理服务器

-    * 关闭代理服务器
-    * 示例
-
-    ```js
-    proxy.close();
-    ```
-* AnyProxy.utils.systemProxyMgr
-  * 管理系统的全局代理配置,方法调用时可能会弹出密码框
-  * 使用示例
-
-  ```js
-  // 配置127.0.0.1:8001为全局http代理服务器
-  AnyProxy.utils.systemProxyMgr.enableGlobalProxy('127.0.0.1', '8001');
-
-  // 关闭全局代理服务器
-  AnyProxy.utils.systemProxyMgr.disableGlobalProxy();
-  ```
-
-* AnyProxy.utils.certMgr
-  * 管理AnyProxy的证书
-  * `AnyProxy.utils.certMgr.ifRootCAFileExists()`
-    * 校验系统内是否存在AnyProxy的根证书
-  * `AnyProxy.utils.certMgr.generateRootCA(callback)`
-    * 生成AnyProxy的rootCA,完成后请引导用户信任.crt文件
-  * 样例
-
-  ```js
-    const AnyProxy = require('AnyProxy');
-    const exec = require('child_process').exec;
-
-    if (!AnyProxy.utils.certMgr.ifRootCAFileExists()) {
-      AnyProxy.utils.certMgr.generateRootCA((error, keyPath) => {
-        // let users to trust this CA before using proxy
-        if (!error) {
-          const certDir = require('path').dirname(keyPath);
-          console.log('The cert is generated at', certDir);
-          const isWin = /^win/.test(process.platform);
-          if (isWin) {
-            exec('start .', { cwd: certDir });
-          } else {
-            exec('open .', { cwd: certDir });
-          }
-        } else {
-          console.error('error when generating rootCA', error);
-        }
-      });
-    }
-  ```
-
-# 代理HTTPS
-* AnyProxy默认不对https请求做处理,如需看到明文信息,需要配置CA证书
-
-> 解析https请求的原理是中间人攻击(man-in-the-middle),用户必须信任AnyProxy生成的CA证书,才能进行后续流程
-
-* 生成证书并解析所有https请求
-
-```bash
-anyproxy-ca #生成rootCA证书,生成后需要手动信任
-anyproxy --intercept #启动AnyProxy,并解析所有https请求
-```
-
-* [附录:如何信任CA证书](#证书配置)
-
-# rule模块
-
-AnyProxy提供了二次开发的能力,你可以用js编写自己的规则模块(rule),来自定义网络请求的处理逻辑。
-
->注意:引用规则前,请务必确保文件来源可靠,以免发生安全问题
-
-规则模块的能力范围包括:
-
-* 拦截并修改正在发送的请求
-  * 可修改内容包括请求头(request header),请求体(request body),甚至是请求的目标地址等
-* 拦截并修改服务端响应
-  * 可修改的内容包括http状态码(status code)、响应头(response header)、响应内容等
-* 拦截https请求,对内容做修改
-  * 本质是中间人攻击(man-in-the-middle attack),需要客户端提前信任AnyProxy生成的CA
-
-### 开发示例
-
-* 举例
-  * 需要编写一个规则模块,在 GET http://httpbin.org/user-agent 的返回值里加上测试信息,并延迟5秒返回
-
-* Step 1,编写规则
-
-  ```js
-  // file: sample.js
-  module.exports = {
-    summary: 'a rule to modify response',
-    *beforeSendResponse(requestDetail, responseDetail) {
-      if (requestDetail.url === 'http://httpbin.org/user-agent') {
-        const newResponse = responseDetail.response;
-        newResponse.body += '-- AnyProxy Hacked! --';
-        return new Promise((resolve, reject) => {
-          setTimeout(() => { // delay
-            resolve({ response: newResponse });
-          }, 5000);
-        });
-      }
-    },
-  };
-  ```
-
-* Step 2, 启动AnyProxy,加载规则
-  * 运行 `anyproxy --rule sample.js`
-
-* Step 3, 测试规则
-
-  * 用curl测试
-    ```bash
-    curl http://httpbin.org/user-agent --proxy http://127.0.0.1:8001
-    ```
-
-  * 用浏览器测试:配置浏览器http代理为 127.0.0.1:8001,访问 http://httpbin.org/user-agent
-
-  * 经过代理服务器后,期望的返回如下
-
-  ```
-  {
-    "user-agent": "curl/7.43.0"
-  }
-  - AnyProxy Hacked!
-  ```
-
-* Step 4, 查看请求信息
-
-  * 浏览器访问http://127.0.0.1:8002 ,界面上能看到刚才的请求信息
-
-### 处理流程
-
-* 处理流程图如下
-
-<img src="https://zos.alipayobjects.com/rmsportal/TWyNuSJtEZBdrdcOMRjE.png" width="550" />
-
-* 当http请求经过代理服务器时,具体处理过程是:
-  * 收集请求所有请求参数,包括method, header, body等
-  * AnyProxy调用规则模块`beforeSendRequest`方法,由模块做处理,返回新的请求参数,或返回响应内容
-  * 如果`beforeSendRequest`返回了响应内容,则立即把此响应返回到客户端(而不再发送到真正的服务端),流程结束。
-  * 根据请求参数,向服务端发出请求,接收服务端响应。
-  * 调用规则模块`beforeSendResponse`方法,由模块对响应内容进行处理
-  * 把响应信息返回给客户端
-
-* 当代理服务器收到https请求时,AnyProxy可以替换证书,对请求做明文解析。
-  * 调用规则模块`beforeDealHttpsRequest`方法,如果返回`true`,会明文解析这个请求,其他请求不处理
-  * 被明文解析后的https请求,处理流程同http一致。未明文解析请求不会再进入规则模块做处理。
-
-
-### 如何引用
-
-如下几种方案都可以用来引用规则模块:
-
-* 使用本地路径
-```bash
-anyproxy --rule ./rule.js
-```
-* 使用在线地址
-```bash
-anyproxy --rule https://sample.com/rule.js
-```
-
-* 使用npm包
-  * AnyProxy使用`require()`加载本地规则,你可以在参数里传入一个本地的npm包路径,或是某个全局安装的npm包
-
-  ```bash
-anyproxy --rule ./myRulePkg/ #本地包
-npm i -g myRulePkg && anyproxy --rule myRulePkg #全局包
-  ```
-
-
-# rule接口文档
-
-规则模块应该符合cmd规范,一个典型的规则模块代码结构如下。模块中所有方法都是可选的,只需实现业务感兴趣的部分即可。
-
-```js
-module.exports = {
-  // 模块介绍
-  summary: 'my customized rule for AnyProxy',
-  // 发送请求前拦截处理
-  *beforeSendRequest(requestDetail) { /* ... */ },
-  // 发送响应前处理
-  *beforeSendResponse(requestDetail, responseDetail) { /* ... */ },
-  // 是否处理https请求
-  *beforeDealHttpsRequest(requestDetail) { /* ... */ },
-  // 请求出错的事件
-  *onError(requestDetail, error) { /* ... */ },
-  // https连接服务器出错
-  *onConnectError(requestDetail, error) { /* ... */ }
-};
-```
-
-> 规则文件中,除了summary,都是由 [co](https://www.npmjs.com/package/co) 驱动的,函数需要满足yieldable。可以返回promise或使用generator函数。

-#### summary(): string | summary:string
-
-* 规则模块的介绍文案,用于AnyProxy提示用户, 可以是一个函数,也可以是一个普通的字符串
-
-### beforeSendRequest
-#### beforeSendRequest(requestDetail)
-
-* AnyProxy向服务端发送请求前,会调用`beforeSendRequest`,并带上参数`requestDetail`
-* `requestDetail`
-  * `protocol` {string} 请求使用的协议,http或者https
-  * `requestOptions` {object} 即将发送的请求配置,供require('http').request作为使用。详见:https://nodejs.org/api/http.html#http_http_request_options_callback
-  * `requestData` {object} 请求Body
-  * `url` {string} 请求url
-  * `_req` {object} 请求的原始request
-* 举例:请求 *anyproxy.io* 时,`requestDetail`参数内容大致如下
-
-  ```js
-  {
-    protocol: 'http',
-    url: 'http://anyproxy.io/',
-    requestOptions: {
-      hostname: 'anyproxy.io',
-      port: 80,
-      path: '/',
-      method: 'GET',
-      headers: {
-        Host: 'anyproxy.io',
-        'Proxy-Connection': 'keep-alive',
-        'User-Agent': '...'
-      }
-    },
-    requestData: '...',
-    _req: { /* ... */}
-  }
-  ```
-
-* 以下几种返回都是合法的
-  * 不做任何处理,返回null
-
-  ```js
-  return null;
-  ```
-
-  * 修改请求协议,如强制改用https发起请求
-
-  ```js
-  return {
-    protocol: 'https'
-  };
-  ```
-
-  * 修改请求参数
-
-  ```js
-  var newOption = Object.assign({}, requestDetail.requestOptions);
-  newOption.path = '/redirect/to/another/path';
-  return {
-    requestOptions: newOption
-  };
-  ```
-  * 修改请求body
-
-  ```js
-  return {
-    requestData: 'my new request data'
-    //这里也可以同时加上requestOptions
-  };
-  ```
-  * 直接返回客户端,不再发起请求,其中`statusCode` `header` 是必选字段
-
-  ```js
-  return {
-    response: {
-      statusCode: 200,
-      header: { 'content-type': 'text/html' },
-      body: 'this could be a <string> or <buffer>'
-    }
-  };
-  ```
-
-### beforeSendResponse
-
-#### beforeSendResponse(requestDetail, responseDetail)
-
-* AnyProxy向客户端发送请求前,会调用`beforeSendResponse`,并带上参数`requestDetail` `responseDetail`
-* `requestDetail` 同`beforeSendRequest`中的参数
-* `responseDetail`
-  * `response` {object} 服务端的返回信息,包括`statusCode` `header` `body`三个字段
-  * `_res` {object} 原始的服务端返回对象
-* 举例,请求 *anyproxy.io* 时,`responseDetail`参数内容大致如下
-
-  ```js
-  {
-    response: {
-      statusCode: 200,
-      header: {
-        'Content-Type': 'image/gif',
-        Connection: 'close',
-        'Cache-Control': '...'
-      },
-      body: '...'
-    },
-    _res: { /* ... */ }
-  }
-  ```
-
-* 以下几种返回都是合法的
-  * 不做任何处理,返回null
-
-  ```js
-  return null;
-  ```
-
-  * 修改返回的状态码
-
-  ```js
-  var newResponse = Object.assign({}, responseDetail.response);
-  newResponse.statusCode = 404;
-  return {
-    response: newResponse
-  };
-  ```
-
-  * 修改返回的内容
-
-  ```js
-  var newResponse = Object.assign({}, responseDetail.response);
-  newResponse.body += '--from anyproxy--';
-  return {
-    response: newResponse
-  };
-  ```
-
-### beforeDealHttpsRequest
-
-#### beforeDealHttpsRequest(requestDetail)
-
-* AnyProxy收到https请求时,会调用`beforeDealHttpsRequest`,并带上参数`requestDetail`
-* 如果配置了全局解析https的参数,则AnyProxy会略过这个调用
-* 只有返回`true`时,AnyProxy才会尝试替换证书、解析https。否则只做数据流转发,无法看到明文数据。
-* 注意:https over http的代理模式中,这里的request是CONNECT请求
-* `requestDetail`
-  * `host` {string} 请求目标的Host,受制于协议,这里无法获取完整url
-  * `_req` {object} 请求的原始request
-* 返回值
-  * `true`或者`false`,表示是否需要AnyProxy替换证书并解析https
-
-### onError
-
-#### onError(requestDetail, error)
-
-* 在请求处理过程中发生错误时,AnyProxy会调用`onError`方法,并提供对应的错误信息
-* 多数场景下,错误会在请求目标服务器的时候发生,比如DNS解析失败、请求超时等
-* `requestDetail` 同`beforeSendRequest`中的参数
-* 以下几种返回都是合法的
-  * 不做任何处理。此时AnyProxy会返回一个默认的错误页。
-
-  ```js
-  return null;
-  ```
-
-  * 返回自定义错误页
-
-  ```js
-  return {
-    response: {
-      statusCode: 200,
-      header: { 'content-type': 'text/html' },
-      body: 'this could be a <string> or <buffer>'
-    }
-  };
-  ```
-
-### onConnectError
-
-#### onConnectError(requestDetail, error)
-
-* AnyProxy在与目标HTTPS服务器建立连接的过程中,如果发生错误,AnyProxy会调用这个方法
-* `requestDetail` 同`beforeDealHttpsRequest`中的参数
-* 此处无法控制向客户端的返回信息,无需返回值。
-
-# rule样例
-
-* 这里提供一些样例,来讲解规则模块的常见用法
-* 你可以通过 `anyproxy --rule http://....js` 来加载模块并体验
-* 用curl发请求测试的方法如下
-  * 直接请求服务器:`curl http://httpbin.org/`
-  * 通过代理服务器请求:`curl http://httpbin.org/ --proxy http://127.0.0.1:8001`
-
-### 使用本地数据
-  * 拦截发送到 http://httpbin.org 的请求,使用本地数据代替服务端返回
-
-```bash
-anyproxy --rule rule_sample/sample_use_local_response.js
-```
-```js
-/* 
-  sample: 
-    intercept all requests toward httpbin.org, use a local response
-  test:
-    curl http://httpbin.org/user-agent --proxy http://127.0.0.1:8001
-*/
-module.exports = {
-  *beforeSendRequest(requestDetail) {
-    const localResponse = {
-      statusCode: 200,
-      header: { 'Content-Type': 'application/json' },
-      body: '{"hello": "this is local response"}'
-    };
-    if (requestDetail.url.indexOf('http://httpbin.org') === 0) {
-      return {
-        response: localResponse
-      };
-    }
-  },
-};
-
-```
-
-### 修改请求头
-  * 修改发送到 httpbin.org 的user-agent
-
-```bash
-anyproxy --rule rule_sample/sample_modify_request_header.js
-```
-```js
-/* 
-  sample: 
-    modify the user-agent in requests toward httpbin.org
-  test:
-    curl http://httpbin.org/user-agent --proxy http://127.0.0.1:8001
-*/
-module.exports = {
-  *beforeSendRequest(requestDetail) {
-    if (requestDetail.url.indexOf('http://httpbin.org') === 0) {
-      const newRequestOptions = requestDetail.requestOptions;
-      newRequestOptions.headers['User-Agent'] = 'AnyProxy/0.0.0';
-      return {
-        requestOptions: newRequestOptions
-      };
-    }
-  },
-};
-
-```
-
-### 修改请求数据
-  * 修改发送到 http://httpbin.org/post 的post数据
-
-```bash
-anyproxy --rule rule_sample/sample_modify_request_data.js
-```
-```js
-/*
-  sample:
-    modify the post data towards http://httpbin.org/post
-  test:
-    curl -H "Content-Type: text/plain" -X POST -d 'original post data' http://httpbin.org/post --proxy http://127.0.0.1:8001
-  expected response:
-    { "data": "i-am-anyproxy-modified-post-data" }
-*/
-module.exports = {
-  summary: 'Rule to modify request data',
-  *beforeSendRequest(requestDetail) {
-    if (requestDetail.url.indexOf('http://httpbin.org/post') === 0) {
-      return {
-        requestData: 'i-am-anyproxy-modified-post-data'
-      };
-    }
-  },
-};
-
-```
-
-### 修改请求的目标地址
-  * 把所有发送到 http://httpbin.org/ 的请求全部改到 http://httpbin.org/user-agent
-
-```bash
-anyproxy --rule rule_sample/sample_modify_request_path.js
-```
-```js
-/* 
-  sample: 
-    redirect all httpbin.org requests to http://httpbin.org/user-agent
-  test:
-    curl http://httpbin.org/any-path --proxy http://127.0.0.1:8001
-  expected response:
-    { "user-agent": "curl/7.43.0" }
-*/
-module.exports = {
-  *beforeSendRequest(requestDetail) {
-    if (requestDetail.url.indexOf('http://httpbin.org') === 0) {
-      const newRequestOptions = requestDetail.requestOptions;
-      newRequestOptions.path = '/user-agent';
-      newRequestOptions.method = 'GET';
-      return {
-        requestOptions: newRequestOptions
-      };
-    }
-  },
-};
-
-```
-
-### 修改请求协议
-  * 把用http协议请求的 http://httpbin.org 改成https并发送
-
-```bash
-anyproxy --rule rule_sample/sample_modify_request_protocol.js
-```
-```js
-/* 
-  sample: 
-    redirect all http requests of httpbin.org to https
-  test:
-    curl 'http://httpbin.org/get?show_env=1' --proxy http://127.0.0.1:8001
-  expected response:
-    { "X-Forwarded-Protocol": "https" }
-*/
-module.exports = {
-  *beforeSendRequest(requestDetail) {
-    if (requestDetail.url.indexOf('http://httpbin.org') === 0) {
-      const newOption = requestDetail.requestOptions;
-      newOption.port = 443;
-      return {
-        protocol: 'https',
-        requestOptions: newOption
-      };
-    }
-  }
-};
-
-```
-
-### 修改返回状态码
-  * 把 所有http://httpbin.org 的返回状态码都改成404
-
-```bash
-anyproxy --rule rule_sample/sample_modify_response_statuscode.js
-```
-```js
-/* 
-  sample: 
-    modify all status code of http://httpbin.org/ to 404
-  test:
-    curl -I 'http://httpbin.org/user-agent' --proxy http://127.0.0.1:8001
-  expected response:
-    HTTP/1.1 404 Not Found
-*/
-module.exports = {
-  *beforeSendResponse(requestDetail, responseDetail) {
-    if (requestDetail.url.indexOf('http://httpbin.org') === 0) {
-      const newResponse = responseDetail.response;
-      newResponse.statusCode = 404;
-      return {
-        response: newResponse
-      };
-    }
-  }
-};
-
-```
-
-### 修改返回头
-  * 在 http://httpbin.org/user-agent 的返回头里加上 X-Proxy-By:AnyProxy
-
-```bash
-anyproxy --rule rule_sample/sample_modify_response_header.js
-```
-```js
-/* 
-  sample: 
-    modify response header of http://httpbin.org/user-agent
-  test:
-    curl -I 'http://httpbin.org/user-agent' --proxy http://127.0.0.1:8001
-  expected response:
-    X-Proxy-By: AnyProxy
-*/
-module.exports = {
-  *beforeSendResponse(requestDetail, responseDetail) {
-    if (requestDetail.url.indexOf('http://httpbin.org/user-agent') === 0) {
-      const newResponse = responseDetail.response;
-      newResponse.header['X-Proxy-By'] = 'AnyProxy';
-      return {
-        response: newResponse
-      };
-    }
-  }
-};
-
-```
-
-### 修改返回内容并延迟
-  * 在 http://httpbin.org/user-agent 的返回最后追加AnyProxy的签名,并延迟5秒
-
-```bash
-anyproxy --rule rule_sample/sample_modify_response_data.js
-```
-```js
-/* 
-  sample: 
-    modify response data of http://httpbin.org/user-agent
-  test:
-    curl 'http://httpbin.org/user-agent' --proxy http://127.0.0.1:8001
-  expected response:
-    { "user-agent": "curl/7.43.0" } -- AnyProxy Hacked! --
-*/
-
-module.exports = {
-  *beforeSendResponse(requestDetail, responseDetail) {
-    if (requestDetail.url === 'http://httpbin.org/user-agent') {
-      const newResponse = responseDetail.response;
-      newResponse.body += '-- AnyProxy Hacked! --';
-      return new Promise((resolve, reject) => {
-        setTimeout(() => { // delay the response for 5s
-          resolve({ response: newResponse });
-        }, 5000);
-      });
-    }
-  },
-};
-
-```

-# 证书配置
-
-### OSX系统信任CA证书
-
-* 类似这种报错都是因为系统没有信任AnyProxy生成的CA所造成的
-
-<img src="https://zos.alipayobjects.com/rmsportal/CBkLGYgvoHAYwNVAYkpk.png" width="450" />
-
-> 警告:CA证书和系统安全息息相关,建议亲自生成,并妥善保管
-
-安装CA:
-
-* 双击打开*rootCA.crt*
-
-* 确认将证书添加到login或system
-
-<img src="https://zos.alipayobjects.com/rmsportal/bCwNUFFpvsmVuljQKrIk.png" width="350" />
-
-* 找到刚刚导入的AnyProxy证书,配置为信任(Always Trust)

-# FAQ
-
-#### Q: 为什么https请求不能进入处理函数?
- A: 以下任意一项都能用来改变https的处理特性:
-     1. 命令行启动AnyProxy时配置`--intercept`参数,按npm模块启动时配置`forceProxyHttps`参数,所有Https请求都会被替换证书并解析
-     2. 规则文件内提供`beforeDealHttpsRequest`方法,返回 *true* 的https请求会被解析
-
-#### Q: 提示 *function is not yieldable*
- * A: 规则模块是用 [co](https://www.npmjs.com/package/co) 驱动的,函数需要满足yieldable。可以使用generator方法或是返回Promise。
-
-#### Q: The connection is not private
-当访问特定的HTTPS站点,AnyProxy会提示该站点不是一个安全的网站,这通常是因为站点的证书设置不能被正确识别导致的(比如,站点的证书是自签发的)。如果您信任该网站,可以用以下方式来继续访问:
-- 命令行直接启动
-
-  通过启动参数 `--ignore-unauthorized-ssl` 来忽略证书认证的错误。需要注意的是,该参数是全局生效的,如果你在此期间访问了其他未知的网站,他们的证书问题也会被忽略,这可能会带来安全隐患。
-
-  ```bash
-  anyproxy -i --ignore-unauthorized-ssl
-  ```
-
-- 在Nodejs代码中启动
-
-  在构造AnyProxy实例的时候,传入参数`dangerouslyIgnoreUnauthorized:true`, 如下:
-
-  ```js
-   const options = {
-    ...,
-    dangerouslyIgnoreUnauthorized: true
-   };
-
-   const anyproxyIns = new AnyProxy.ProxyCore(options);
-   anyproxyIns.start();
-  ```
-
-  *通过这种方式初始化的AnyProxy,其配置也是全局性的,所有网站的证书问题都会被忽略*
-
-- 通过自定义的Rule来修改
-
-  我们自然也可以借助自定义的Rule来实现这个效果,而且我们还可以控制到只允许指定网址的证书错误,对不在列表的网址,进行证书的强验证。
-
-  ```js
-  module.exports = {
-    *beforeSendRequest(requestDetail) {
-      if (requestDetail.url.indexOf('https://the-site-you-know.com') === 0) {
-        const newRequestOptions = requestDetail.requestOptions;
-        // 设置属性 rejectUnauthorized 为 false
-        newRequestOptions.rejectUnauthorized = false;
-        return {
-          requestOptions: newRequestOptions
-        };
-      }
-    },
-  };
-  ```

-<h3 id="q-can-not-deal-https-request-in-rule-module">Q: can not deal https request in rule module.</h3>
-<ul>
-<li>A: Any of these options could be used to change the way AnyProxy deall https requests<ol>
-<li>config <code>--intercept</code> when luanching AnyProxy via cli, or use <code>forceProxyHttps</code> when using as an npm module</li>
-<li>place a <code>beforeDealHttpsRequest</code> function in your rule file and determine which request to intercept by your own.</li>
-</ol>
-</li>
-</ul>
-<h3 id="q-get-an-error-says-function-is-not-yieldable">Q: get an error says <em>function is not yieldable</em></h3>
-<ul>
-<li>A: Rule module is driven by <a href="https://www.npmjs.com/package/co" target="_blank">co</a>. The functions inside should  be yieldable, i.e. return a promise or be a generator function.</li>
-</ul>
-<h3 id="q-the-connection-is-not-private">Q: The connection is not private</h3>
-<p>AnyProxy will propmt this message when the certification of the site you&apos;re visiting is not issued by a common known CA. This happens when the certification is self-signed. If you know and trust it, you can ignore the error as below.</p>
-<ul>
-<li><p>If you run AnyProxy by command line
-Pass in the option <code>--ignore-unauthorized-ssl</code> to ignore the certification errors, please mind that the option will be active for all connections.</p>
-<pre><code class="lang-bash">anyproxy -i --ignore-unauthorized-ssl
-</code></pre>
-</li>
-<li><p>If you run AnyProxy by Nodejs
-Pass in the option <code>dangerouslyIgnoreUnauthorized:true</code>, like this:</p>
-<pre><code class="lang-js"><span class="hljs-keyword">const</span> options = {
- ...,
- dangerouslyIgnoreUnauthorized: <span class="hljs-literal">true</span>
-};
-
-<span class="hljs-keyword">const</span> anyproxyIns = <span class="hljs-keyword">new</span> AnyProxy.ProxyCore(options);
-anyproxyIns.start();
-</code></pre>
-<p><em>This is also a global option, all certification errors will be ignored</em></p>
-</li>
-<li><p>With the help of AnyProxy Rule
-You can change the request with rule of course. For this scenario, all you need is to pass in an option to Nodejs <code>Http.rquest</code>, as we do in AnyProxy. A simple demo below:</p>
-<pre><code class="lang-js"><span class="hljs-built_in">module</span>.exports = {
-  *beforeSendRequest(requestDetail) {
-    <span class="hljs-keyword">if</span> (requestDetail.url.indexOf(<span class="hljs-string">&apos;https://the-site-you-know.com&apos;</span>) === <span class="hljs-number">0</span>) {
-      <span class="hljs-keyword">const</span> newRequestOptions = requestDetail.requestOptions;
-      <span class="hljs-comment">// set rejectUnauthorized as false</span>
-      newRequestOptions.rejectUnauthorized = <span class="hljs-literal">false</span>;
-      <span class="hljs-keyword">return</span> {
-        requestOptions: newRequestOptions
-      };
-    }
-  },
-};
-</code></pre>
-<p>And we get a bonous here, AnyProxy will only ignore the errors for the site(s) we want it to!</p>
