# QueryList
`QueryList` is a simple, elegant, extensible PHP crawler (spider) ,based on phpQuery.
# QueryList 简介
`QueryList`是一套简洁、优雅、可扩展的PHP采集工具(爬虫)基于phpQuery。
## Features
- Have the same CSS3 DOM selector as jQuery
- Have the same DOM manipulation API as jQuery
- Have a generic list crawling program
- Have a strong HTTP request suite, easy to achieve such as: simulated landing, forged browser, HTTP proxy and other complex network requests
- Have a messy code solution
- Have powerful content filtering, you can use the jQuey selector to filter content
- Has a high degree of modular design, scalability and strong
- Have an expressive API
- Has a wealth of plug-ins
## 特性
- 拥有与jQuery完全相同的CSS3 DOM选择器
- 拥有与jQuery完全相同的DOM操作API
- 拥有通用的列表采集方案
- 拥有强大的HTTP请求套件轻松实现如模拟登陆、伪造浏览器、HTTP代理等意复杂的网络请求
- 拥有乱码解决方案
- 拥有强大的内容过滤功能可使用jQuey选择器来过滤内容
- 拥有高度的模块化设计,扩展性强
- 拥有富有表现力的API
- 拥有高质量文档
- 拥有丰富的插件
- 拥有专业的问答社区和交流群
Through plug-ins you can easily implement things like:
- Multithreaded crawl
- Crawl JavaScript dynamic rendering page (PhantomJS/headless WebKit)
- Image downloads to local
- Simulate browser behavior such as submitting Form forms
- Web crawler
通过插件可以轻松实现诸如:
- 多线程采集
- 采集JavaScript动态渲染的页面 (PhantomJS/headless WebKit)
- 图片本地化
- 模拟浏览器行为提交Form表单
- 网络爬虫
- .....
## Requirements
## 环境要求
- PHP >= 7.0
## Installation
By Composer installation:
> 如果你的PHP版本还停留在PHP5或者不会使用Composer,你可以选择使用QueryList3,QueryList3支持php5.3以及手动安装。
QueryList3 文档:http://v3.querylist.cc
## 安装
通过Composer安装:
```
composer require jaeger/querylist
```

#### HTTP Client
- Carry cookie login GitHub
```php
//采集新浪微博需要登录才能访问的页面
$ql = QueryList::get('http://weibo.com','param1=testvalue & params2=somevalue',[
//Crawl GitHub content
$ql = QueryList::get('https://github.com','param1=testvalue & params2=somevalue',[

echo $ql->find('title')->text();
//输出: 我的首页 微博-随时随地发现新鲜事
$userName = $ql->find('.header-nav-current-user>.css-truncate-target')->text();
echo $userName;
```
- 使用Http代理
- Use the Http proxy
```php
$urlParams = ['param1' => 'testvalue','params2' => 'somevalue'];
$opts = [
// 设置http代理
// Set the http proxy
'proxy' => 'http://222.141.11.17:8118',
//设置超时时间,单位:秒
//Set the timeout time in seconds
'timeout' => 30,
// 伪造http头

- 模拟登录
- Analog login
```php
// 用post登录
// Post login
$ql = QueryList::post('http://xxxx.com/login',[
'username' => 'admin',
'password' => '123456'
])->get('http://xxx.com/admin');
//采集需要登录才能访问的页面
// Crawl pages that need to be logged in to access
$ql->get('http://xxx.com/admin/page');
//echo $ql->getHtml();
```
#### Form表单操作
模拟登陆GitHub
#### Submit forms
Login GitHub
```php
// 获取QueryList实例
// Get the QueryList instance
$ql = QueryList::getInstance();
//获取到登录表单
// Get the login form
$form = $ql->get('https://github.com/login')->find('form');
//填写GitHub用户名和密码
// Fill in the GitHub username and password
$form->find('input[name=login]')->val('your github username or email');
$form->find('input[name=password]')->val('your github password');
//序列化表单数据
// Serialize the form data
$fromData = $form->serializeArray();
$postData = [];
foreach ($fromData as $item) {
$postData[$item['name']] = $item['value'];
}
//提交登录表单
// Submit the login form
$actionUrl = 'https://github.com'.$form->attr('action');
$ql->post($actionUrl,$postData);
//判断登录是否成功
// To determine whether the login is successful
// echo $ql->getHtml();
$userName = $ql->find('.header-nav-current-user>.css-truncate-target')->text();
if($userName)
{
echo '登录成功!欢迎你:'.$userName;
echo 'Login successful ! Welcome:'.$userName;
}else{
echo '登录失败!';
echo 'Login failed !';
}
```
#### Bind功能扩展
自定义扩展一个`myHttp`方法:
#### Bind function extension
Customize the extension of a `myHttp` method:
```php
$ql = QueryList::getInstance();
//绑定一个myHttp方法到QueryList对象
//Bind a `myHttp` method to the QueryList object
$ql->bind('myHttp',function ($url){
$html = file_get_contents($url);
$this->setHtml($html);
return $this;
});
//然后就可以通过注册的名字来调用
// And then you can call by the name of the binding
$data = $ql->myHttp('https://toutiao.io')->find('h3 a')->texts();
print_r($data->all());
```
或者把实现体封装到class然后这样绑定:
Or package to class, and then bind:
```php
$ql->bind('myHttp',function ($url){
return new MyHttp($this,$url);
});
```
#### 插件使用
- 使用PhantomJS插件采集JavaScript动态渲染的页面:
#### Plugin used
- Use the PhantomJS plugin to crawl JavaScript dynamically rendered pages:
```php
// 安装时设置PhantomJS二进制文件路径
// Set the PhantomJS binary file path during installation
$ql = QueryList::use(PhantomJs::class,'/usr/local/bin/phantomjs');
// 采集今日头条手机版
$data = $ql->browser('https://m.toutiao.com')->find('p')->texts();
// Crawl「500px」all picture links
$data = $ql->browser('https://500px.com/editors')->find('img')->attrs('src');
print_r($data->all());
// 使用HTTP代理
$ql->browser('https://m.toutiao.com',false,[
// Use the HTTP proxy
$ql->browser('https://500px.com/editors',false,[
'--proxy' => '192.168.1.42:8080',
'--proxy-type' => 'http'
])
```
- 使用CURL多线程插件,多线程采集GitHub排行榜:

```php
$ql = QueryList::use(CurlMulti::class);
