Python开发网站目录扫描器的实现

有人问为什么要去扫描网站目录：懂的人自然懂

这个Python脚本的特点：

1.基本完善

2.界面美观（只是画了个图案）

3.可选参数增加了线程数

4.User Agent细节处理

5.多线程显示进度

扫描目标：Metasploitable Linux

代码：WebDirScanner.py：

需要一个字典文件：

我存进去了一些，一部分是确定存在的目录

dict.txt

index.php
login
dvwa
phpMyAdmin
dav
twiki
login.php

结果：得到一个HTML文件：

<a href="http://192.168.232.129/twiki" rel="external nofollow" target="_blank">http://192.168.232.129/twiki</a>

</br><a href="http://192.168.232.129/index.php" rel="external nofollow" target="_blank">http://192.168.232.129/index.php</a>

</br><a href="http://192.168.232.129/phpMyAdmin" rel="external nofollow" target="_blank">http://192.168.232.129/phpMyAdmin</a>
