GoIyov

介绍

golang 代理

安装教程

 go get -u github.com/nicecp/GoIyov

支持特性

• HTTP/HTTPS代理
• TLS/SSL解密
• MITM(中间人攻击)
• 自定义DNS
• Certificate缓存
• Statistic统计(开发中)

证书安装

$ go run main.go [-cert]
    -cert 安装服务端证书，支持MacOS(需root权限)/Windows系统

使用说明

// 生成代理类
func (proxy *Proxy) New() *Proxy

type Delegate interface {
	BeforeRequest(entity *entity.Entity)
	BeforeResponse(entity *entity.Entity, err error)
	ErrorLog(err error)
}
// 生成代理类, MITM事件处理
func (proxy *Proxy) NewWithDelegate(delegate Delegate) *Proxy

// 将host解析至remote地址
func (proxy *Proxy) AddDnsRecord(host,remote string)

代理

package main
import (
	"github.com/nicecp/GoIyov"
	"net/http"
	"time"
)

func main() {
	proxy := GoIyov.New()
	// 添加自定义DNS
	proxy.AddDnsRecord("localhost-x","127.0.0.1")
	server := &http.Server{
		Addr:         ":8888",
		Handler:	  http.HandlerFunc(func(rw http.ResponseWriter, req *http.Request) {
			proxy.ServerHandler(rw, req)
		}),
		ReadTimeout:  30 * time.Second,
		WriteTimeout: 30 * time.Second,
	}
	err := server.ListenAndServe()
	if err != nil {
		panic(err)
	}
}

MITM(中间人攻击)

package main

import (
	"fmt"
	"github.com/nicecp/GoIyov"
	"github.com/nicecp/GoIyov/entity"
	"net/http"
	"time"
)

type Handler struct {
	GoIyov.Delegate
}

func (handler *Handler) BeforeRequest(entity *entity.Entity) {
	fmt.Printf("%+v",entity.GetRequestBody())
}
func (handler *Handler) BeforeResponse(entity *entity.Entity, err error) {
	fmt.Printf("%+v",entity.GetResponseBody())
}
func (handler *Handler) ErrorLog(err error) {}

func main() {
	proxy := GoIyov.NewWithDelegate(&Handler{})
	server := &http.Server{
		Addr: ":8888",
		Handler: http.HandlerFunc(func(rw http.ResponseWriter, req *http.Request) {
			proxy.ServerHandler(rw, req)
		}),
		ReadTimeout:  30 * time.Second,
		WriteTimeout: 30 * time.Second,
	}
	err := server.ListenAndServe()
	if err != nil {
		panic(err)
	}
}

移动端如何调试

请确保手机及电脑连接同一个局域网，并将移动设备HTTP代理设置为本机`IP:PORT`
1. 浏览器打开 `goiyov.io/ssl`
2. 安装并信任证书

建议使用MITM特性，以便查看明文内容
