Golang写的一款子域名爆破工具

由于疫情的横行，只能躲在家里进行学习，根据这几天的学习成果，写了一款子域名爆破的工具。

该工具开源代码如下，哪里需要改进的可以自行修改，根据字典来爆破，支持多线程。

package main

import (
	"bufio"
	"fmt"
	"net"
	"net/http"
	"os"
	"strconv"
	"strings"
	"time"
)

type aoligei struct { // 结构体
	Channel chan string
	Domain string
	Dict string
	Num int
	Taskend int
} //整体结构体

func (this *aoligei) Sondomain() (resurl string) { //域名生成器
	var buffer=make([]byte,1024*9999)
	file,err:=os.Open(this.Dict)
	if err!=nil{
		fmt.Println("文件不存在")
		os.Exit(0)
	}
	f:=bufio.NewReader(file)
	n,_:=f.Read(buffer)
	url:=string(buffer[:n])
	urlok:=strings.Split(url,"\r\n")
	this.Num++
	if this.Num>=len(urlok){
		return "END"
	}
	if strings.Contains(this.Domain,"http"){
		this.Domain=strings.Replace(this.Domain,"http://","",-1)
	}
	if strings.Contains(this.Domain,"https"){
		this.Domain=strings.Replace(this.Domain,"https://","",-1)
	}
	resurl="http://" +urlok[this.Num]+"."+this.Domain
	return
}// 该方法控制域名的生成
func (this *aoligei) Geturl() { //中枢处理器

	}

下面是程序的测试结果，确实可以爆破出东西来。
