HTTP

HTTP代理是利用HTTP协议的CONNECT方法实现的代理服务。

标准HTTP代理

一个最简单的无加密无认证的HTTP代理服务。

gost -L http://:8080

services:
- name: service-0
  addr: :8080
  handler:
    type: http
  listener:
    type: tcp

标准HTTP代理(开启认证)

一个无加密具有用户认证的HTTP代理服务。

gost -L http://user:pass@:8080

services:
- name: service-0
  addr: :8080
  handler:
    type: http
    auth:
      username: user
      password: pass
  listener:
    type: tcp

参数选项

自定义HTTP头

通过header选项可以自定义请求和响应头部信息。

services:
- name: service-0
  addr: :8080
  handler:
    type: http
    chain: chain-0
    header:
      Proxy-Agent: "gost/3.0"
      foo: bar
  listener:
    type: tcp
chains:
- name: chain-0
  hops:
  - name: hop-0
    nodes:
    - name: node-0
      addr: :8443
      connector:
        type: http
        metadata:
          header:
            User-Agent: "gost/3.0"
            foo: bar
      dialer:
        type: tcp

数据通道

HTTP代理可以与各种数据通道组合使用。

HTTP Over TLS

标准HTTPS代理服务。

gost -L https://:8443

等同于

gost -L http+tls://:8443

services:
- name: service-0
  addr: :8443
  handler:
    type: http
  listener:
    type: tls

HTTP Over Websocket

gost -L http+ws://:8080

gost -L http+wss://:8080

services:
- name: service-0
  addr: :8080
  handler:
    type: http
  listener:
    type: ws
    # type: wss

HTTP Over KCP

gost -L http+kcp://:8080

services:
- name: service-0
  addr: :8080
  handler:
    type: http
  listener:
    type: kcp

UDP数据转发

HTTP代理在标准协议基础之上扩展了对UDP数据的支持，实现UDP-Over-HTTP功能。 HTTP代理服务UDP转发功能默认关闭，需要通过udp选项开启。

服务端

gost -L http://:8080?udp=true

services:
- name: service-0
  addr: :8080
  handler:
    type: http
    metadata:
      udp: true
  listener:
    type: tcp

客户端

gost -L udp://:10053/1.1.1.1:53 -F http://:8080

services:
- name: service-0
  addr: :10053
  handler:
    type: udp
    chain: chain-0
  listener:
    type: udp
  forwarder:
    nodes:
    - name: target-0
      addr: 1.1.1.1:53
chains:
- name: chain-0
  hops:
  - name: hop-0
    nodes:
    - name: node-0
      addr: :8080
      connector:
        type: http
      dialer:
        type: tcp
