Python Tips - 迅雷,快车,qq下载地址转换

可以转换迅雷,快车和qq下载地址的模块

迅雷,快车和qq下载都有专用的地址,其转换规则如下:

1、普通地址转换为迅雷地址
在原地址前面加”AA”，后面加”ZZ”(注：不包括引号)，即AAhttp://**ZZ
然后用base64编码后,在地址前加thunder://.

2、普通地址转换为快车地址
在原地址前后都加上”[FLASHGET]“(注：不包括引号)，地址变为
[FLASHGET]http://**[FLASHGET]
用base64编码后,在地址前加flashget://，后面还要加上”&字符串”，字符串随便什么都行.

3、普通地址转换为旋风地址
旋风相对就简单多了，将原地址直接base64编码,然后在地址前加qqdl://

逆向及反着来一次.

python地址转换代码如下:

#! /usr/bin/env python
# PyThunder.py
# transfer special download address to the normal http address
# including thunder, flashget and qq download
