Python爬取酷狗MP3音频

概述分析问题音频url点入某个音乐的播放界面，通过F12-Network，分析数据，可以看到有一个index.php?..返回数据中有一个play_url，打开后正是我们需要的音频。查看该url的headers，其params参数如下，通过反复不同的几次尝试，得知r、callback、dfid、mid、platid这几项不变，而通过初步的requests 分析问题音频url

点入某个音乐的播放界面，通过F12-Network，分析数据，可以看到有一个index.PHP?..返回数据中有一个play_url，打开后正是我们需要的音频。

查看该url的headers，其params参数如下，通过反复不同的几次尝试，得知r、callback、dfID、mID、platID这几项不变，而通过初步的requests尝试，发现最后一项'_'可有可无，改变的只有hash和album_ID两项。

搜索url

得知改变的只有两项后，那就容易多了，在搜索歌曲界面Network，发现song?...该url返回值中有hash和album_ID存在，我们之后只用搜索结果第一项（一般要搜的歌曲排名第一）。

同样分析其params参数，改变的只有keyword、signature、clIEnttime、mID、uuID。后三者可以比较容易看出其为毫秒级时间戳（13位），keyword也挺容易明白，signature哪里找呢？通过全局搜索signature，发现有一个Js文件中含有该关键词。

在274行发现h.signature = faultylabs.MD5(o.join("")),初步理解为signature是o内部元素拼接成字符串，对其加上断点并将o加入watch。

0: "NVPh5oo715z5DIWAeQlhmdsWXXQV4hwt"1: "bitrate=0"2: "callback=callback123"3: "clIEnttime=1612580098162"4: "clIEntver=2000"5: "dfID=-"6: "inputtype=0"7: "iscorrection=1"8: "isfuzzy=0"9: "keyword=花海"10: "mID=1612580098162"11: "page=1"12: "pagesize=30"13: "platform=WebFilter"14: "privilege_filter=0"15: "srcappID=2919"16: "tag=em"17: "userID=-1"18: "uuID=1612580098162"19: "NVPh5oo715z5DIWAeQlhmdsWXXQV4hwt"length: 20

在watch里不难发现o为一个长度为20的数组，之后我们按之前理解将字符串拼接。

之后要Js解密，这谁会？反正我不会 0.0，那也有办法，用python调用Js文件。在274行分析为md5加密，往前找看看有没有相关函数，果真有一个，将其保存为kugou.Js

之后用python的pyexecJs库调用， 但是注意调用的时候的名字是execJs。
