本版本过旧,我不再提供支持!请看最新的发布版本!

(早猜出来了,看最新code。。。)

 

猜不出sign是怎么做的。

求大家一起动手。

            我在你代码里面只看到带appkey的 sign_this = calc_sign(‘appkey={APPKEY}&cid={cid}

            就像你那例子 参数里面不带appkey
            http://interface.bilibili.com/playurl?cid=1338722&player=1&ts=1406832881&sign=7037e644d3b4159c80372af8bd6fff72

            不带appkey的情况下
            md5(cid=1338722&player=1&ts=1406832881)
            可得不到 7037e644d3b4159c80372af8bd6fff72

            当然带key 连sign都不用验证就能直接访问 但不是想要这种方法 是想知道上面那种不带key的算法

    你把b站播放器 的play.swf 反编译一下 里边getsign的function 看看应该就能明白怎么算的了吧
    这里大概贴一点 不完整的
    package com.bilibili.interfaces {
    public function getSign(_arg1:string):string{ var _local4:int; var _local2 = null; var _local26:int; var _local25:int; var _local19:int; var _local15:int; var _local14:int; var _local7:int; var _local22:int;

          sign_this = calc_sign('appkey={APPKEY}&cid={cid}{SECRETKEY}'.format(APPKEY = APPKEY, cid = cid, SECRETKEY = SECRETKEY))
          #----------------------------------------------------------------------
          def calc_sign(string):
          """str/any->str
          return MD5."""
          return str(hashlib.md5(str(string).encode('utf-8')).hexdigest())

          我用FFDec.

      请问用什么工具反汇编的? 我用的工具 找不到getSign函数的具体实现 package com.bilibili.interfaces 下面也没有 只找到在其他地方调用的
