115地址加密解密分析

手工解析115网盘地址方法
例如 115 网盘上某文件的下载地址为

http://u.115.com/file/t6d903d466

这其中的 t6d903d466 称之为提取码。

把提取码加到下面的地址后面，然后打开就可以看到真实的文件下载地址了。

http://u.115.com/?ct=upload_api&ac=get_pick_code_info&version=1160&pickcode=

加上提取码后，地址为

http://u.115.com/?ct=upload_api&ac=get_pick_code_info&version=1160&pickcode=t6d903d466

打开上面的地址，看到的是一串 JSON，

,”Message”:”ok”,”Version”:1160}

其中”Url”:后面的字符串就是文件真实下载地址，一般会有三个地址(分别表示电信、网通、备份)。

第一个地址为

http://15.tel.115cdn.com/pickdown/M00/4F/EE/d5NqvEyb7m0AAAAABv1h

AEk82Tw6352427/00-00.zip?key=a31a1b535f809a96a5fca0f75c5dfed5&key1=4ca05

67b&file=00-00.zip&key2=35382e3231322e37342e313631

把其中的转义字符”/”替换为”/”得到的就是真实地址
