### 插件
### 客户端插件
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)。

### Manage Plugin
frp manage plugin is aim to extend frp's ability without modifing self code.
It runs as a process and listen on a port to provide RPC interface. Before frps doing some operations, frps will send RPC requests to manage plugin and do operations by it's response.
### RPC request
Support HTTP first.
When manage plugin accept the operation request, it can give three different responses.
* Reject operation and return the 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. Assume here is `/handler`.
Request
```
POST /handler
{
"version": "0.1.0",
"op": "Login",
"content": {
... // Operation info
}
}
Request Header
X-Frp-Reqid: for tracing
```
Response
Error if not return 200 http code.
Reject opeartion
```
{
"reject": true,
"reject_reason": "invalid user"
}
```
Allow operation and keep original content
```
{
"reject": false,
"unchange": true
}
```
Allow opeartion and modify content
```
{
"unchange": "false",
"content": {
... // Replaced content
}
}
```
### Operation
Now it supports `Login` and `NewProxy`.
#### Login
Client login operation
```
{
"content": {
"version": <string>,
"hostname": <string>,
"os": <string>,
"arch": <string>,
"user": <string>,
"timestamp": <int64>,
"privilege_key": <string>,
"run_id": <string>,
"pool_count": <int>,
"metas": map<string>string
}
}
```
#### NewProxy
Create new proxy
```
{
"content": {
"user": {
"user": <string>,
"metas": map<string>string
},
"proxy_name": <string>,
"proxy_type": <string>,
"use_encryption": <bool>,
"use_compression": <bool>,
"group": <string>,
"group_key": <string>,
// tcp and udp only
"remote_port": <int>,
// http and https only
"custom_domains": []<string>,
"subdomain": <string>,
"locations": <string>,
"http_user": <string>,
"http_pwd": <string>,
"host_header_rewrite": <string>,
"headers": map<string>string,
"metas": map<string>string
}
}
```
### manage plugin configure
```ini
[common]
bind_port = 7000
[plugin.user-manager]
addr = 127.0.0.1:9000
path = /handler
ops = Login
[plugin.port-manager]
addr = 127.0.0.1:9001
path = /handler
ops = NewProxy
```
addr: plugin listen on.
path: http request url path.
ops: opeartions plugin needs handle.
### meta data
Meta data will be sent to manage plugin in each RCP request.
Meta data start with `meta_`. It can be configured in `common` and each proxy.
```
# frpc.ini
[common]
server_addr = 127.0.0.1
server_port = 7000
user = fake
meta_token = fake
meta_version = 1.0.0
[ssh]
type = tcp
local_port = 22
remote_port = 6000
meta_id = 123
```

### 服务端管理插件
frp 管理插件的作用是在不侵入自身代码的前提下,扩展 frp 服务端的能力。
frp 管理插件会以单独进程的形式运行,并且监听在一个端口上,对外提供 RPC 接口,响应 frps 的请求。
frps 在执行某些操作前,会根据配置向管理插件发送 RPC 请求,根据管理插件的响应来执行相应的操作。
### RPC 请求
管理插件接收到操作请求后,可以给出三种回应。
* 拒绝操作,需要返回拒绝操作的原因。
* 允许操作,不需要修改操作内容。
* 允许操作,对操作请求进行修改后,返回修改后的内容。
### 接口
接口路径可以在 frps 配置中为每个插件单独配置,这里以 `/handler` 为例。
Request
```
POST /handler
{
"version": "0.1.0",
"op": "Login",
"content": {
... // 具体的操作信息
}
}
请求 Header
X-Frp-Reqid: 用于追踪请求
```
Response
非 200 的返回都认为是请求异常。
拒绝执行操作
```
{
"reject": true,
"reject_reason": "invalid user"
}
```
允许且内容不需要变动
```
{
"reject": false,
"unchange": true
}
```
允许且需要替换操作内容
```
{
"unchange": "false",
"content": {
... // 替换后的操作信息,格式必须和请求时的一致
}
}
```
### 操作类型
目前插件支持管理的操作类型有 `Login``NewProxy`
#### Login
用户登录操作信息
```
{
"content": {
"version": <string>,
"hostname": <string>,
"os": <string>,
"arch": <string>,
"user": <string>,
"timestamp": <int64>,
"privilege_key": <string>,
"run_id": <string>,
"pool_count": <int>,
"metas": map<string>string
}
}
```
#### NewProxy
创建代理的相关信息
```
{
"content": {
"user": {
"user": <string>,
"metas": map<string>string
},
"proxy_name": <string>,
"proxy_type": <string>,
"use_encryption": <bool>,
"use_compression": <bool>,
"group": <string>,
"group_key": <string>,
// tcp and udp only
"remote_port": <int>,
// http and https only
"custom_domains": []<string>,
"subdomain": <string>,
"locations": <string>,
"http_user": <string>,
"http_pwd": <string>,
"host_header_rewrite": <string>,
"headers": map<string>string,
"metas": map<string>string
}
}
```
### frps 中插件配置
```ini
[common]
bind_port = 7000
[plugin.user-manager]
addr = 127.0.0.1:9000
path = /handler
ops = Login
[plugin.port-manager]
addr = 127.0.0.1:9001
path = /handler
ops = NewProxy
```
addr: 插件监听的网络地址。
path: 插件监听的 HTTP 请求路径。
ops: 插件需要处理的操作列表,多个 op 以英文逗号分隔。
### 元数据
为了减少 frps 的代码修改,同时提高管理插件的扩展能力,在 frpc 的配置文件中引入自定义元数据的概念。元数据会在调用 RPC 请求时发送给插件。
元数据以 `meta_` 开头,可以配置多个,元数据分为两种,一种配置在 `common` 下,一种配置在各个 proxy 中。
```
# frpc.ini
[common]
server_addr = 127.0.0.1
server_port = 7000
user = fake
meta_token = fake
meta_version = 1.0.0
[ssh]
type = tcp
local_port = 22
remote_port = 6000
meta_id = 123
```
