-## 为什么使用 frp ？
-
-通过在具有公网 IP 的节点上部署 frp 服务端，可以轻松地将内网服务穿透到公网，同时提供诸多专业的功能特性，这包括：
-
-* 客户端服务端通信支持 TCP、QUIC、KCP 以及 Websocket 等多种协议。
-* 采用 TCP 连接流式复用，在单个连接间承载更多请求，节省连接建立时间，降低请求延迟。
-* 代理组间的负载均衡。
-* 端口复用，多个服务通过同一个服务端端口暴露。
-* 支持 P2P 通信，流量不经过服务器中转，充分利用带宽资源。
-* 多个原生支持的客户端插件（静态文件查看，HTTPS/HTTP 协议转换，HTTP、SOCK5 代理等），便于独立使用 frp 客户端完成某些工作。
-* 高度扩展性的服务端插件系统，易于结合自身需求进行功能扩展。
-* 服务端和客户端 UI 页面。

 ## 开发状态
 
-frp 目前已被很多公司广泛用于测试、生产环境。
+frp 仍然处于开发阶段，未经充分测试与验证，不推荐用于生产环境。
 
 master 分支用于发布稳定版本，dev 分支用于开发，您可以尝试下载最新的 release 版本进行测试。
 
-我们正在进行 v2 大版本的开发，将会尝试在各个方面进行重构和升级，且不会与 v1 版本进行兼容，预计会持续较长的一段时间。
+**目前的交互协议可能随时改变，不保证向后兼容，升级新版本时需要注意公告说明同时升级服务端和客户端。**
 
-现在的 v0 版本将会在合适的时间切换为 v1 版本并且保证兼容性，后续只做 bug 修复和优化，不再进行大的功能性更新。
+## 架构
 
-### 关于 v2 的一些说明
+![architecture](/doc/pic/architecture.png)
 
-v2 版本的复杂度和难度比我们预期的要高得多。我只能利用零散的时间进行开发，而且由于上下文经常被打断，效率极低。由于这种情况可能会持续一段时间，我们仍然会在当前版本上进行一些优化和迭代，直到我们有更多空闲时间来推进大版本的重构，或者也有可能放弃一次性的重构，而是采用渐进的方式在当前版本上逐步做一些可能会导致不兼容的修改。
+## 使用示例
 
-v2 的构想是基于我多年在云原生领域，特别是在 K8s 和 ServiceMesh 方面的工作经验和思考。它的核心是一个现代化的四层和七层代理，类似于 envoy。这个代理本身高度可扩展，不仅可以用于实现内网穿透的功能，还可以应用于更多领域。在这个高度可扩展的内核基础上，我们将实现 frp v1 中的所有功能，并且能够以一种更加优雅的方式实现原先架构中无法实现或不易实现的功能。同时，我们将保持高效的开发和迭代能力。
+根据对应的操作系统及架构，从 [Release](https://github.com/fatedier/frp/releases) 页面下载最新版本的程序。
 
-除此之外，我希望 frp 本身也成为一个高度可扩展的系统和平台，就像我们可以基于 K8s 提供一系列扩展能力一样。在 K8s 上，我们可以根据企业需求进行定制化开发，例如使用 CRD、controller 模式、webhook、CSI 和 CNI 等。在 frp v1 中，我们引入了服务端插件的概念，实现了一些简单的扩展性。但是，它实际上依赖于简单的 HTTP 协议，并且需要用户自己启动独立的进程和管理。这种方式远远不够灵活和方便，而且现实世界的需求千差万别，我们不能期望一个由少数人维护的非营利性开源项目能够满足所有人的需求。
+将 **frps** 及 **frps.ini** 放到具有公网 IP 的机器上。
 
-最后，我们意识到像配置管理、权限验证、证书管理和管理 API 等模块的当前设计并不够现代化。尽管我们可能在 v1 版本中进行一些优化，但确保兼容性是一个令人头疼的问题，需要投入大量精力来解决。
+将 **frpc** 及 **frpc.ini** 放到处于内网环境的机器上。
 
-非常感谢您对 frp 的支持。
+### 通过 ssh 访问公司内网机器
 
-## 文档
+1. 修改 frps.ini 文件，这里使用了最简化的配置：
 
-完整文档已经迁移至 [https://gofrp.org](https://gofrp.org)。
+  ```ini
+  # frps.ini
+  [common]
+  bind_port = 7000
+  ```
+
+2. 启动 frps：
+
+  `./frps -c ./frps.ini`
+
+3. 修改 frpc.ini 文件，假设 frps 所在服务器的公网 IP 为 x.x.x.x；
+
+  ```ini
+  # frpc.ini
+  [common]
+  server_addr = x.x.x.x
+  server_port = 7000
+  
+  [ssh]
+  type = tcp
+  local_ip = 127.0.0.1
+  local_port = 22
+  remote_port = 6000
+  ```
+
+4. 启动 frpc：
+
+  `./frpc -c ./frpc.ini`
+
+5. 通过 ssh 访问内网机器，假设用户名为 test：
+
+  `ssh -oPort=6000 test@x.x.x.x`
+
+### 通过自定义域名访问部署于内网的 web 服务
+
+有时想要让其他人通过域名访问或者测试我们在本地搭建的 web 服务，但是由于本地机器没有公网 IP，无法将域名解析到本地的机器，通过 frp 就可以实现这一功能，以下示例为 http 服务，https 服务配置方法相同， vhost_http_port 替换为 vhost_https_port， type 设置为 https 即可。
+
+1. 修改 frps.ini 文件，设置 http 访问端口为 8080：
+
+  ```ini
+  # frps.ini
+  [common]
+  bind_port = 7000
+  vhost_http_port = 8080
+  ```
+
+2. 启动 frps；
+
+  `./frps -c ./frps.ini`
+
+3. 修改 frpc.ini 文件，假设 frps 所在的服务器的 IP 为 x.x.x.x，local_port 为本地机器上 web 服务对应的端口, 绑定自定义域名 `www.yourdomain.com`:
+
+  ```ini
+  # frpc.ini
+  [common]
+  server_addr = x.x.x.x
+  server_port = 7000
+
+  [web]
+  type = http
+  local_port = 80
+  custom_domains = www.yourdomain.com
+  ```
+
+4. 启动 frpc：
+
+  `./frpc -c ./frpc.ini`
+
+5. 将 `www.yourdomain.com` 的域名 A 记录解析到 IP `x.x.x.x`，如果服务器已经有对应的域名，也可以将 CNAME 记录解析到服务器原先的域名。
+
+6. 通过浏览器访问 `http://www.yourdomain.com:8080` 即可访问到处于内网机器上的 web 服务。
+
+### 转发 DNS 查询请求
+
+DNS 查询请求通常使用 UDP 协议，frp 支持对内网 UDP 服务的穿透，配置方式和 TCP 基本一致。
+
+1. 修改 frps.ini 文件：
+
+  ```ini
+  # frps.ini
+  [common]
+  bind_port = 7000
+  ```
+
+2. 启动 frps：
+
+  `./frps -c ./frps.ini`
+
+3. 修改 frpc.ini 文件，设置 frps 所在服务器的 IP 为 x.x.x.x，转发到 Google 的 DNS 查询服务器 `8.8.8.8` 的 udp 53 端口：
+
+  ```ini
+  # frpc.ini
+  [common]
+  server_addr = x.x.x.x
+  server_port = 7000
+  
+  [dns]
+  type = udp
+  local_ip = 8.8.8.8
+  local_port = 53
+  remote_port = 6000
+  ```
+
+4. 启动 frpc：
+
+  `./frpc -c ./frpc.ini`
+
+5. 通过 dig 测试 UDP 包转发是否成功，预期会返回 `www.google.com` 域名的解析结果：
+
+  `dig @x.x.x.x -p 6000 www.google.com`
+
+### 转发 Unix域套接字
+
+通过 tcp 端口访问内网的 unix域套接字(例如和 docker daemon 通信)。
+
+frps 的部署步骤同上。
+
+1. 启动 frpc，启用 `unix_domain_socket` 插件，配置如下：
+
+  ```ini
+  # frpc.ini
+  [common]
+  server_addr = x.x.x.x
+  server_port = 7000
+  
+  [unix_domain_socket]
+  type = tcp
+  remote_port = 6000
+  plugin = unix_domain_socket
+  plugin_unix_path = /var/run/docker.sock
+  ```
+
+2. 通过 curl 命令查看 docker 版本信息
+
+  `curl http://x.x.x.x:6000/version`
+
+### 对外提供简单的文件访问服务
+
+通过 `static_file` 插件可以对外提供一个简单的基于 HTTP 的文件访问服务。
+
+frps 的部署步骤同上。
+
+1. 启动 frpc，启用 `static_file` 插件，配置如下：
+
+  ```ini
+  # frpc.ini
+  [common]
+  server_addr = x.x.x.x
+  server_port = 7000
+
+  [test_static_file]
+  type = tcp
+  remote_port = 6000
+  plugin = static_file
+  # 要对外暴露的文件目录
+  plugin_local_path = /tmp/file
+  # 访问 url 中会被去除的前缀，保留的内容即为要访问的文件路径
+  plugin_strip_prefix = static
+  plugin_http_user = abc
+  plugin_http_passwd = abc
+  ```
+
+2. 通过浏览器访问 `http://x.x.x.x:6000/static/` 来查看位于 `/tmp/file` 目录下的文件，会要求输入已设置好的用户名和密码。
+
+### 安全地暴露内网服务
+
+对于某些服务来说如果直接暴露于公网上将会存在安全隐患。
+
+使用 **stcp(secret tcp)** 类型的代理可以避免让任何人都能访问到要穿透的服务，但是访问者也需要运行另外一个 frpc。
+
+以下示例将会创建一个只有自己能访问到的 ssh 服务代理。
+
+frps 的部署步骤同上。
+
+1. 启动 frpc，转发内网的 ssh 服务，配置如下，不需要指定远程端口：
+
+  ```ini
+  # frpc.ini
+  [common]
+  server_addr = x.x.x.x
+  server_port = 7000
+
+  [secret_ssh]
+  type = stcp
+  # 只有 sk 一致的用户才能访问到此服务
+  sk = abcdefg
+  local_ip = 127.0.0.1
+  local_port = 22
+  ```
+
+2. 在要访问这个服务的机器上启动另外一个 frpc，配置如下：
+
+  ```ini
+  # frpc.ini
+  [common]
+  server_addr = x.x.x.x
+  server_port = 7000
+
+  [secret_ssh_visitor]
+  type = stcp
+  # stcp 的访问者
+  role = visitor
+  # 要访问的 stcp 代理的名字
+  server_name = secret_ssh
+  sk = abcdefg
+  # 绑定本地端口用于访问 ssh 服务
+  bind_addr = 127.0.0.1
+  bind_port = 6000
+  ```
+
+3. 通过 ssh 访问内网机器，假设用户名为 test：
+
+  `ssh -oPort=6000 test@127.0.0.1`
+
+### 点对点内网穿透
+
+frp 提供了一种新的代理类型 **xtcp** 用于应对在希望传输大量数据且流量不经过服务器的场景。
+
+使用方式同 **stcp** 类似，需要在两边都部署上 frpc 用于建立直接的连接。
+
+目前处于开发的初级阶段，并不能穿透所有类型的 NAT 设备，所以穿透成功率较低。穿透失败时可以尝试 **stcp** 的方式。
+
+1. frps 除正常配置外需要额外配置一个 udp 端口用于支持该类型的客户端:
+
+  ```ini
+  bind_udp_port = 7001
+  ```
+
+2. 启动 frpc，转发内网的 ssh 服务，配置如下，不需要指定远程端口:
+
+  ```ini
+  # frpc.ini
+  [common]
+  server_addr = x.x.x.x
+  server_port = 7000
+
+  [p2p_ssh]
+  type = xtcp
+  # 只有 sk 一致的用户才能访问到此服务
+  sk = abcdefg
+  local_ip = 127.0.0.1
+  local_port = 22
+  ```
+
+3. 在要访问这个服务的机器上启动另外一个 frpc，配置如下:
+
+  ```ini
+  # frpc.ini
+  [common]
+  server_addr = x.x.x.x
+  server_port = 7000
+
+  [p2p_ssh_visitor]
+  type = xtcp
+  # xtcp 的访问者
+  role = visitor
+  # 要访问的 xtcp 代理的名字
+  server_name = p2p_ssh
+  sk = abcdefg
+  # 绑定本地端口用于访问 ssh 服务
+  bind_addr = 127.0.0.1
+  bind_port = 6000
+  ```
+
+4. 通过 ssh 访问内网机器，假设用户名为 test:
+
+  `ssh -oPort=6000 test@127.0.0.1`
+
+## 功能说明
+
+### 配置文件
+
+由于 frp 目前支持的功能和配置项较多，未在文档中列出的功能可以从完整的示例配置文件中发现。
+
+[frps 完整配置文件](./conf/frps_full.ini)
+
+[frpc 完整配置文件](./conf/frpc_full.ini)
+
+### 配置文件模版渲染
+
+配置文件支持使用系统环境变量进行模版渲染，模版格式采用 Go 的标准格式。
+
+示例配置如下:
+
+```ini
+# frpc.ini
+[common]
+server_addr = {{ .Envs.FRP_SERVER_ADDR }}
+server_port = 7000
+
+[ssh]
+type = tcp
+local_ip = 127.0.0.1
+local_port = 22
+remote_port = {{ .Envs.FRP_SSH_REMOTE_PORT }}
+```
+
+启动 frpc 程序:
+
+```
+export FRP_SERVER_ADDR="x.x.x.x"
+export FRP_SSH_REMOTE_PORT="6000"
+./frpc -c ./frpc.ini
+```
+
+frpc 会自动使用环境变量渲染配置文件模版，所有环境变量需要以 `.Envs` 为前缀。
+
+### Dashboard
+
+通过浏览器查看 frp 的状态以及代理统计信息展示。
+
+**注：Dashboard 尚未针对大量的 proxy 数据展示做优化，如果出现 Dashboard 访问较慢的情况，请不要启用此功能。**
+
+需要在 frps.ini 中指定 dashboard 服务使用的端口，即可开启此功能：
+
+```ini
+[common]
+dashboard_port = 7500
+# dashboard 用户名密码，默认都为 admin
+dashboard_user = admin
+dashboard_pwd = admin
+```
+
+打开浏览器通过 `http://[server_addr]:7500` 访问 dashboard 界面，用户名密码默认为 `admin`。
+
+![dashboard](/doc/pic/dashboard.png)
+
+### Admin UI
+
+Admin UI 可以帮助用户通过浏览器来查询和管理客户端的 proxy 状态和配置。
+
+需要在 frpc.ini 中指定 admin 服务使用的端口，即可开启此功能：
+
+```ini
+[common]
+admin_addr = 127.0.0.1
+admin_port = 7400
+admin_user = admin
+admin_pwd = admin
+```
+
+打开浏览器通过 `http://127.0.0.1:7400` 访问 Admin UI，用户名密码默认为 `admin`。
+
+如果想要在外网环境访问 Admin UI，将 7400 端口映射出去即可，但需要重视安全风险。
+
+### 身份验证
+
+服务端和客户端的 common 配置中的 `token` 参数一致则身份验证通过。
+
+### 加密与压缩
+
+这两个功能默认是不开启的，需要在 frpc.ini 中通过配置来为指定的代理启用加密与压缩的功能，压缩算法使用 snappy：
+
+```ini
+# frpc.ini
+[ssh]
+type = tcp
+local_port = 22
+remote_port = 6000
+use_encryption = true
+use_compression = true
+```
+
+如果公司内网防火墙对外网访问进行了流量识别与屏蔽，例如禁止了 ssh 协议等，通过设置 `use_encryption = true`，将 frpc 与 frps 之间的通信内容加密传输，将会有效防止流量被拦截。
+
+如果传输的报文长度较长，通过设置 `use_compression = true` 对传输内容进行压缩，可以有效减小 frpc 与 frps 之间的网络流量，加快流量转发速度，但是会额外消耗一些 cpu 资源。
+
+#### TLS
+
+从 v0.25.0 版本开始 frpc 和 frps 之间支持通过 TLS 协议加密传输。通过在 `frpc.ini` 的 `common` 中配置 `tls_enable = true` 来启用此功能，安全性更高。
+
+为了端口复用，frp 建立 TLS 连接的第一个字节为 0x17。
+
+**注意: 启用此功能后除 xtcp 外，不需要再设置 use_encryption。**
+
+### 客户端热加载配置文件
+
+当修改了 frpc 中的代理配置，可以通过 `frpc reload` 命令来动态加载配置文件，通常会在 10 秒内完成代理的更新。
+
+启用此功能需要在 frpc 中启用 admin 端口，用于提供 API 服务。配置如下：
+
+```ini
+# frpc.ini
+[common]
+admin_addr = 127.0.0.1
+admin_port = 7400
+```
+
+之后执行重启命令：
+
+`frpc reload -c ./frpc.ini`
+
+等待一段时间后客户端会根据新的配置文件创建、更新、删除代理。
+
+**需要注意的是，[common] 中的参数除了 start 外目前无法被修改。**
+
+### 客户端查看代理状态
+
+frpc 支持通过 `frpc status -c ./frpc.ini` 命令查看代理的状态信息，此功能需要在 frpc 中配置 admin 端口。
+
+### 端口白名单
+
+为了防止端口被滥用，可以手动指定允许哪些端口被使用，在 frps.ini 中通过 `allow_ports` 来指定：
+
+```ini
+# frps.ini
+[common]
+allow_ports = 2000-3000,3001,3003,4000-50000
+```
+
+`allow_ports` 可以配置允许使用的某个指定端口或者是一个范围内的所有端口，以 `,` 分隔，指定的范围以 `-` 分隔。
+
+### 端口复用
+
+目前 frps 中的 `vhost_http_port` 和 `vhost_https_port` 支持配置成和 `bind_port` 为同一个端口，frps 会对连接的协议进行分析，之后进行不同的处理。
+
+例如在某些限制较严格的网络环境中，可以将 `bind_port` 和 `vhost_https_port` 都设置为 443。
+
+后续会尝试允许多个 proxy 绑定同一个远端端口的不同协议。
+
+### TCP 多路复用
+
+从 v0.10.0 版本开始，客户端和服务器端之间的连接支持多路复用，不再需要为每一个用户请求创建一个连接，使连接建立的延迟降低，并且避免了大量文件描述符的占用，使 frp 可以承载更高的并发数。
+
+该功能默认启用，如需关闭，可以在 frps.ini 和 frpc.ini 中配置，该配置项在服务端和客户端必须一致：
+
+```ini
+# frps.ini 和 frpc.ini 中
+[common]
+tcp_mux = false
+```
+
+### 底层通信可选 kcp 协议
+
+从 v0.12.0 版本开始，底层通信协议支持选择 kcp 协议，在弱网环境下传输效率提升明显，但是会有一些额外的流量消耗。
+
+开启 kcp 协议支持：
+
+1. 在 frps.ini 中启用 kcp 协议支持，指定一个 udp 端口用于接收客户端请求：
+
+  ```ini
+  # frps.ini
+  [common]
+  bind_port = 7000
+  # kcp 绑定的是 udp 端口，可以和 bind_port 一样
+  kcp_bind_port = 7000
+  ```
+
+2. 在 frpc.ini 指定需要使用的协议类型，目前只支持 tcp 和 kcp。其他代理配置不需要变更：
+
+  ```ini
+  # frpc.ini
+  [common]
+  server_addr = x.x.x.x
+  # server_port 指定为 frps 的 kcp_bind_port
+  server_port = 7000
+  protocol = kcp
+  ```
+
+3. 像之前一样使用 frp，需要注意开放相关机器上的 udp 的端口的访问权限。
+
+### 连接池
+
+默认情况下，当用户请求建立连接后，frps 才会请求 frpc 主动与后端服务建立一个连接。当为指定的代理启用连接池后，frp 会预先和后端服务建立起指定数量的连接，每次接收到用户请求后，会从连接池中取出一个连接和用户连接关联起来，避免了等待与后端服务建立连接以及 frpc 和 frps 之间传递控制信息的时间。
+
+这一功能比较适合有大量短连接请求时开启。
+
+1. 首先可以在 frps.ini 中设置每个代理可以创建的连接池上限，避免大量资源占用，客户端设置超过此配置后会被调整到当前值：
+
+  ```ini
+  # frps.ini
+  [common]
+  max_pool_count = 5
+  ```
+
+2. 在 frpc.ini 中为客户端启用连接池，指定预创建连接的数量：
+
+  ```ini
+  # frpc.ini
+  [common]
+  pool_count = 1
+  ```
+
+### 负载均衡
+
+可以将多个相同类型的 proxy 加入到同一个 group 中，从而实现负载均衡的功能。
+目前只支持 tcp 类型的 proxy。
+
+```ini
+# frpc.ini
+[test1]
+type = tcp
+local_port = 8080
+remote_port = 80
+group = web
+group_key = 123
+
+[test2]
+type = tcp
+local_port = 8081
+remote_port = 80
+group = web
+group_key = 123
+```
+
+用户连接 frps 服务器的 80 端口，frps 会将接收到的用户连接随机分发给其中一个存活的 proxy。这样可以在一台 frpc 机器挂掉后仍然有其他节点能够提供服务。
+
+要求 `group_key` 相同，做权限验证，且 `remote_port` 相同。
+
+### 健康检查
+
+通过给 proxy 加上健康检查的功能，可以在要反向代理的服务出现故障时，将这个服务从 frps 中摘除，搭配负载均衡的功能，可以用来实现高可用的架构，避免服务单点故障。
+
+在每一个 proxy 的配置下加上 `health_check_type = {type}` 来启用健康检查功能。
+
+**type** 目前可选 tcp 和 http。
+
+tcp 只要能够建立连接则认为服务正常，http 会发送一个 http 请求，服务需要返回 2xx 的状态码才会被认为正常。
+
+tcp 示例配置如下：
+
+```ini
+# frpc.ini
+[test1]
+type = tcp
+local_port = 22
+remote_port = 6000
+# 启用健康检查，类型为 tcp
+health_check_type = tcp
+# 建立连接超时时间为 3 秒
+health_check_timeout_s = 3
+# 连续 3 次检查失败，此 proxy 会被摘除
+health_check_max_failed = 3
+# 每隔 10 秒进行一次健康检查
+health_check_interval_s = 10
+```
+
+http 示例配置如下：
+
+```ini
+# frpc.ini
+[web]
+type = http
+local_ip = 127.0.0.1
+local_port = 80
+custom_domains = test.yourdomain.com
+# 启用健康检查，类型为 http
+health_check_type = http
+# 健康检查发送 http 请求的 url，后端服务需要返回 2xx 的 http 状态码
+health_check_url = /status
+health_check_interval_s = 10
+health_check_max_failed = 3
+health_check_timeout_s = 3
+```
+
+### 修改 Host Header
+
+通常情况下 frp 不会修改转发的任何数据。但有一些后端服务会根据 http 请求 header 中的 host 字段来展现不同的网站，例如 nginx 的虚拟主机服务，启用 host-header 的修改功能可以动态修改 http 请求中的 host 字段。该功能仅限于 http 类型的代理。
+
+```ini
+# frpc.ini
+[web]
+type = http
+local_port = 80
+custom_domains = test.yourdomain.com
+host_header_rewrite = dev.yourdomain.com
+```
+
+原来 http 请求中的 host 字段 `test.yourdomain.com` 转发到后端服务时会被替换为 `dev.yourdomain.com`。
+
+### 设置 HTTP 请求的 header
+
+对于 `type = http` 的代理，可以设置在转发中动态添加的 header 参数。
+
+```ini
+# frpc.ini
+[web]
+type = http
+local_port = 80
+custom_domains = test.yourdomain.com
+host_header_rewrite = dev.yourdomain.com
+header_X-From-Where = frp
+```
+
+对于参数配置中所有以 `header_` 开头的参数(支持同时配置多个)，都会被添加到 http 请求的 header 中，根据如上的配置，会在请求的 header 中加上 `X-From-Where: frp`。
+
+### 获取用户真实 IP
+
+目前只有 **http** 类型的代理支持这一功能，可以通过用户请求的 header 中的 `X-Forwarded-For` 和 `X-Real-IP` 来获取用户真实 IP。
+
+### 通过密码保护你的 web 服务
+
+由于所有客户端共用一个 frps 的 http 服务端口，任何知道你的域名和 url 的人都能访问到你部署在内网的 web 服务，但是在某些场景下需要确保只有限定的用户才能访问。
+
+frp 支持通过 HTTP Basic Auth 来保护你的 web 服务，使用户需要通过用户名和密码才能访问到你的服务。
+
+该功能目前仅限于 http 类型的代理，需要在 frpc 的代理配置中添加用户名和密码的设置。
+
+```ini
+# frpc.ini
+[web]
+type = http
+local_port = 80
+custom_domains = test.yourdomain.com
+http_user = abc
+http_pwd = abc
+```
+
+通过浏览器访问 `http://test.yourdomain.com`，需要输入配置的用户名和密码才能访问。
+
+### 自定义二级域名
+
+在多人同时使用一个 frps 时，通过自定义二级域名的方式来使用会更加方便。
+
+通过在 frps 的配置文件中配置 `subdomain_host`，就可以启用该特性。之后在 frpc 的 http、https 类型的代理中可以不配置 `custom_domains`，而是配置一个 `subdomain` 参数。
+
+只需要将 `*.{subdomain_host}` 解析到 frps 所在服务器。之后用户可以通过 `subdomain` 自行指定自己的 web 服务所需要使用的二级域名，通过 `{subdomain}.{subdomain_host}` 来访问自己的 web 服务。
+
+```ini
+# frps.ini
+[common]
+subdomain_host = frps.com
+```
+
+将泛域名 `*.frps.com` 解析到 frps 所在服务器的 IP 地址。
+
+```ini
+# frpc.ini
+[web]
+type = http
+local_port = 80
+subdomain = test
+```
+
+frps 和 frpc 都启动成功后，通过 `test.frps.com` 就可以访问到内网的 web 服务。
+
+**注：如果 frps 配置了 `subdomain_host`，则 `custom_domains` 中不能是属于 `subdomain_host` 的子域名或者泛域名。**
+
+同一个 http 或 https 类型的代理中 `custom_domains`  和 `subdomain` 可以同时配置。
+
+### URL 路由
+
+frp 支持根据请求的 URL 路径路由转发到不同的后端服务。
+
+通过配置文件中的 `locations` 字段指定一个或多个 proxy 能够匹配的 URL 前缀(目前仅支持最大前缀匹配，之后会考虑正则匹配)。例如指定 `locations = /news`，则所有 URL 以 `/news` 开头的请求都会被转发到这个服务。
+
+```ini
+# frpc.ini
+[web01]
+type = http
+local_port = 80
+custom_domains = web.yourdomain.com
+locations = /
+
+[web02]
+type = http
+local_port = 81
+custom_domains = web.yourdomain.com
+locations = /news,/about
+```
+
+按照上述的示例配置后，`web.yourdomain.com` 这个域名下所有以 `/news` 以及 `/about` 作为前缀的 URL 请求都会被转发到 web02，其余的请求会被转发到 web01。
+
+### 通过代理连接 frps
+
+在只能通过代理访问外网的环境内，frpc 支持通过 HTTP PROXY 和 frps 进行通信。
+
+可以通过设置 `HTTP_PROXY` 系统环境变量或者通过在 frpc 的配置文件中设置 `http_proxy` 参数来使用此功能。
+
+仅在 `protocol = tcp` 时生效。
+
+```ini
+# frpc.ini
+[common]
+server_addr = x.x.x.x
+server_port = 7000
+http_proxy = http://user:pwd@192.168.1.128:8080
+```
+
+### 范围端口映射
+
+在 frpc 的配置文件中可以指定映射多个端口，目前只支持 tcp 和 udp 的类型。
+
+这一功能通过 `range:` 段落标记来实现，客户端会解析这个标记中的配置，将其拆分成多个 proxy，每一个 proxy 以数字为后缀命名。
+
+例如要映射本地 6000-6005, 6007 这6个端口，主要配置如下：
+
+```ini
+# frpc.ini
+[range:test_tcp]
+type = tcp
+local_ip = 127.0.0.1
+local_port = 6000-6006,6007
+remote_port = 6000-6006,6007
+```
+
+实际连接成功后会创建 8 个 proxy，命名为 `test_tcp_0, test_tcp_1 ... test_tcp_7`。
+
+### 插件
+
+默认情况下，frpc 只会转发请求到本地 tcp 或 udp 端口。
+
+插件模式是为了在客户端提供更加丰富的功能，目前内置的插件有 `unix_domain_socket`、`http_proxy`、`socks5`、`static_file`。具体使用方式请查看[使用示例](#使用示例)。
+
+通过 `plugin` 指定需要使用的插件，插件的配置参数都以 `plugin_` 开头。使用插件后 `local_ip` 和 `local_port` 不再需要配置。
+
+使用 **http_proxy** 插件的示例:
+
+```ini
+# frpc.ini
+[http_proxy]
+type = tcp
+remote_port = 6000
+plugin = http_proxy
+plugin_http_user = abc
+plugin_http_passwd = abc
+```
+
+`plugin_http_user` 和 `plugin_http_passwd` 即为 `http_proxy` 插件可选的配置参数。

-### Server Plugin
-
-frp server plugin is aimed to extend frp's ability without modifying the Golang code.
-
-An external server should run in a different process receiving RPC calls from frps.
-Before frps is doing some operations, it will send RPC requests to notify the external RPC server and act according to its response.
-
-### RPC request
-
-RPC requests are based on JSON over HTTP.
-
-When a server plugin accepts an operation request, it can respond with three different responses:
-
-* Reject operation and return a reason.
-* Allow operation and keep original content.
-* Allow operation and return modified content.
-
-### Interface
-
-HTTP path can be configured for each manage plugin in frps. We'll assume for this example that it's `/handler`.
-
-A request to the RPC server will look like:
-
-```
-POST /handler?version=0.1.0&op=Login
-{
-    "version": "0.1.0",
-    "op": "Login",
-    "content": {
-        ... // Operation info
-    }
-}
-
-Request Header:
-X-Frp-Reqid: for tracing
-```
-
-The response can look like any of the following:
-

-### Server Plugin Configuration
-
-```toml
-# frps.toml
-bindPort = 7000
-
-[[httpPlugins]]
-name = "user-manager"
-addr = "127.0.0.1:9000"
-path = "/handler"
-ops = ["Login"]
-
-[[httpPlugins]]
-name = "port-manager"
-addr = "127.0.0.1:9001"
-path = "/handler"
-ops = ["NewProxy"]
-```
-
-- addr: the address where the external RPC service listens. Defaults to http. For https, specify the schema: `addr = "https://127.0.0.1:9001"`.
-- path: http request url path for the POST request.
-- ops: operations plugin needs to handle (e.g. "Login", "NewProxy", ...).
-- tlsVerify: When the schema is https, we verify by default. Set this value to false if you want to skip verification.
-
-### Metadata
-
-Metadata will be sent to the server plugin in each RPC request.
-
-There are 2 types of metadata entries - global one and the other under each proxy configuration.
-Global metadata entries will be sent in `Login` under the key `metas`, and in any other RPC request under `user.metas`.
-Metadata entries under each proxy configuration will be sent in `NewProxy` op only, under `metas`.
-
-This is an example of metadata entries:
-
-```toml
-# frpc.toml
-serverAddr = "127.0.0.1"
-serverPort = 7000
-user = "fake"
-metadatas.token = "fake"
-metadatas.version = "1.0.0"
-
-[[proxies]]
-name = "ssh"
-type = "tcp"
-localPort = 22
-remotePort = 6000
-metadatas.id = "123"

-### SSH Tunnel Gateway
-
-*Added in v0.53.0*
-
-### Concept
-
-SSH supports reverse proxy capabilities [rfc](https://www.rfc-editor.org/rfc/rfc4254#page-16).
-
-frp supports listening on an SSH port on the frps side to achieve TCP protocol proxying using the SSH -R protocol. This mode does not rely on frpc.
-
-SSH reverse tunneling proxying and proxying SSH ports through frp are two different concepts. SSH reverse tunneling proxying is essentially a basic reverse proxying accomplished by connecting to frps via an SSH client when you don't want to use frpc.
-
-```toml
-# frps.toml
-sshTunnelGateway.bindPort = 0
-sshTunnelGateway.privateKeyFile = ""
-sshTunnelGateway.autoGenPrivateKeyPath = ""
-sshTunnelGateway.authorizedKeysFile = ""
-```
-
-| Field | Type | Description | Required |
-| :--- | :--- | :--- | :--- |
-| bindPort| int | The ssh server port that frps listens on.| Yes |
-| privateKeyFile | string | Default value is empty. The private key file used by the ssh server. If it is empty, frps will read the private key file under the autoGenPrivateKeyPath path. It can reuse the /home/user/.ssh/id_rsa file on the local machine, or a custom path can be specified.| No |
-| autoGenPrivateKeyPath  | string |Default value is ./.autogen_ssh_key. If the file does not exist or its content is empty, frps will automatically generate RSA private key file content and store it in this file.|No|
-| authorizedKeysFile  | string |Default value is empty. If it is empty, ssh client authentication is not authenticated. If it is not empty, it can implement ssh password-free login authentication. It can reuse the local /home/user/.ssh/authorized_keys file or a custom path can be specified.| No |
-
-### Basic Usage
-
-#### Server-side frps
-
-Minimal configuration:
-
-```toml
-sshTunnelGateway.bindPort = 2200
-```
-
-Place the above configuration in frps.toml and run `./frps -c frps.toml`. It will listen on port 2200 and accept SSH reverse proxy requests.
-
-Note:
-
-1. When using the minimal configuration, a `.autogen_ssh_key` private key file will be automatically created in the current working directory. The SSH server of frps will use this private key file for encryption and decryption. Alternatively, you can reuse an existing private key file on your local machine, such as `/home/user/.ssh/id_rsa`.
-
-2. When running frps in the minimal configuration mode, connecting to frps via SSH does not require authentication. It is strongly recommended to configure a token in frps and specify the token in the SSH command line.
-
-#### Client-side SSH
-
-The command format is:
-
-```bash
-ssh -R :80:{local_ip:port} v0@{frps_address} -p {frps_ssh_listen_port} {tcp|http|https|stcp|tcpmux} --remote_port {real_remote_port} --proxy_name {proxy_name} --token {frp_token}
-```
-
-1. `--proxy_name` is optional, and if left empty, a random one will be generated.
-2. The username for logging in to frps is always "v0" and currently has no significance, i.e., `v0@{frps_address}`.
-3. The server-side proxy listens on the port determined by `--remote_port`.
-4. `{tcp|http|https|stcp|tcpmux}` supports the complete command parameters, which can be obtained by using `--help`. For example: `ssh -R :80::8080 v0@127.0.0.1 -p 2200 http --help`.
-5. The token is optional, but for security reasons, it is strongly recommended to configure the token in frps.
-
-#### TCP Proxy
-
-```bash
-ssh -R :80:127.0.0.1:8080 v0@{frp_address} -p 2200 tcp --proxy_name "test-tcp" --remote_port 9090
-```
-
-This sets up a proxy on frps that listens on port 9090 and proxies local service on port 8080.
-
-```bash
-frp (via SSH) (Ctrl+C to quit)
-
-User: 
-ProxyName: test-tcp
-Type: tcp
-RemoteAddress: :9090
-```
-
-Equivalent to:
-
-```bash
-frpc tcp --proxy_name "test-tcp" --local_ip 127.0.0.1 --local_port 8080 --remote_port 9090
-```
-
-More parameters can be obtained by executing `--help`.
-
-#### HTTP Proxy
-
-```bash
-ssh -R :80:127.0.0.1:8080 v0@{frp address} -p 2200 http --proxy_name "test-http"  --custom_domain test-http.frps.com
-```
-
-Equivalent to:
-```bash
-frpc http --proxy_name "test-http" --custom_domain test-http.frps.com
-```
-
-You can access the HTTP service using the following command:
-
-curl 'http://test-http.frps.com'
-
-More parameters can be obtained by executing --help.
-
-#### HTTPS/STCP/TCPMUX Proxy
-
-To obtain the usage instructions, use the following command:
-
-```bash
-ssh -R :80:127.0.0.1:8080 v0@{frp address} -p 2200 {https|stcp|tcpmux} --help
-```
-
-### Advanced Usage
-
-#### Reusing the id_rsa File on the Local Machine
-
-```toml
-# frps.toml
-sshTunnelGateway.bindPort = 2200
-sshTunnelGateway.privateKeyFile = "/home/user/.ssh/id_rsa"
-```
-
-During the SSH protocol handshake, public keys are exchanged for data encryption. Therefore, the SSH server on the frps side needs to specify a private key file, which can be reused from an existing file on the local machine. If the privateKeyFile field is empty, frps will automatically create an RSA private key file.
-
-#### Specifying the Auto-Generated Private Key File Path
-
-```toml
-# frps.toml
-sshTunnelGateway.bindPort = 2200
-sshTunnelGateway.autoGenPrivateKeyPath = "/var/frp/ssh-private-key-file"
-```
-
-frps will automatically create a private key file and store it at the specified path.
-
-Note: Changing the private key file in frps can cause SSH client login failures. If you need to log in successfully, you can delete the old records from the `/home/user/.ssh/known_hosts` file.
-
-#### Using an Existing authorized_keys File for SSH Public Key Authentication
-
-```toml
-# frps.toml
-sshTunnelGateway.bindPort = 2200
-sshTunnelGateway.authorizedKeysFile = "/home/user/.ssh/authorized_keys"
-```
-
-The authorizedKeysFile is the file used for SSH public key authentication, which contains the public key information for users, with one key per line.
-
-If authorizedKeysFile is empty, frps won't perform any authentication for SSH clients. Frps does not support SSH username and password authentication.
-
-You can reuse an existing `authorized_keys` file on your local machine for client authentication.
-
-Note: authorizedKeysFile is for user authentication during the SSH login phase, while the token is for frps authentication. These two authentication methods are independent. SSH authentication comes first, followed by frps token authentication. It is strongly recommended to enable at least one of them. If authorizedKeysFile is empty, it is highly recommended to enable token authentication in frps to avoid security risks.
-
-#### Using a Custom authorized_keys File for SSH Public Key Authentication
-
-```toml
-# frps.toml
-sshTunnelGateway.bindPort = 2200
-sshTunnelGateway.authorizedKeysFile = "/var/frps/custom_authorized_keys_file"
-```
-
-Specify the path to a custom `authorized_keys` file.
-
-Note that changes to the authorizedKeysFile file may result in SSH authentication failures. You may need to re-add the public key information to the authorizedKeysFile.

-# Virtual Network (VirtualNet)
-
-*Alpha feature added in v0.62.0*
-
-The VirtualNet feature enables frp to create and manage virtual network connections between clients and visitors through a TUN interface. This allows for IP-level routing between machines, extending frp beyond simple port forwarding to support full network connectivity.
-
-> **Note**: VirtualNet is an Alpha stage feature and is currently unstable. Its configuration methods and functionality may be adjusted and changed at any time in subsequent versions. Do not use this feature in production environments; it is only recommended for testing and evaluation purposes.
-
-## Enabling VirtualNet
-
-Since VirtualNet is currently an alpha feature, you need to enable it with feature gates in your configuration:
-
-```toml
-# frpc.toml
-featureGates = { VirtualNet = true }
-```
-
-## Basic Configuration
-
-To use the virtual network capabilities:
-
-1. First, configure your frpc with a virtual network address:
-
-```toml
-# frpc.toml
-serverAddr = "x.x.x.x"
-serverPort = 7000
-featureGates = { VirtualNet = true }
-
-# Configure the virtual network interface
-virtualNet.address = "100.86.0.1/24"
-```
-
-2. For client proxies, use the `virtual_net` plugin:
-
-```toml
-# frpc.toml (server side)
-[[proxies]]
-name = "vnet-server"
-type = "stcp"
-secretKey = "your-secret-key"
-[proxies.plugin]
-type = "virtual_net"
-```
-
-3. For visitor connections, configure the `virtual_net` visitor plugin:
-
-```toml
-# frpc.toml (client side)
-serverAddr = "x.x.x.x"
-serverPort = 7000
-featureGates = { VirtualNet = true }
-
-# Configure the virtual network interface
-virtualNet.address = "100.86.0.2/24"
-
-[[visitors]]
-name = "vnet-visitor"
-type = "stcp"
-serverName = "vnet-server"
-secretKey = "your-secret-key"
-bindPort = -1
-[visitors.plugin]
-type = "virtual_net"
-destinationIP = "100.86.0.1"
-```
-
-## Requirements and Limitations
-
-- **Permissions**: Creating a TUN interface requires elevated permissions (root/admin)
-- **Platform Support**: Currently supported on Linux and macOS
-- **Default Status**: As an alpha feature, VirtualNet is disabled by default
-- **Configuration**: A valid IP/CIDR must be provided for each endpoint in the virtual network
