直接上图：
..
1.直接访问默认扫描当前IP的C段，获取标题、web容器.
2.可以自定义传入需要扫描的段，传入参数ip即可
3.代理访问参数为url，可简单的访问内网的web，对了，我还加载了网站里的css，做到尽量看上去和直接访问的效果一样

参数：
ip [需要探测的ip段]
url [需要请求的地址]
其他参数：
thread [指定线程数]
decode [指定编码]
referer [伪造referer]
cookie [伪造cookie]
待完善：
1.一个C段，可能有多种编码格式，所以指定一个参数是有问题的。
2.端口可以修改传入一个数组，支持探测多个端口80，8080..
3.代理访问功能并不完善，例如加载js、加载图片、超链接替换成代理访问的链接、表单替换支持真实请求..
对了，其实这个主要是用于偷懒或者内网渗透时，各种代理总是遇到问题出不来。坐等大神写个完善版本的。
（我自己来还得慢慢改。）
PS：很久没写代码，代码渣，多线程还是没学会。看来代码就是得天天写才能熟练。
