python爬取QQVIP音乐

QQ音乐相比于网易云音乐加密部分基本上没有,但是就是QQ音乐的页面与页面之间的联系太强了,,导致下载一个音乐需要分析前面多个页面,找数据。。太繁琐了

 

1、爬取链接:https://y.qq.com/

 

 

首先随便找一个页面先点进去

python爬取QQVIP音乐

 

 

 

2、点击播放歌曲会打开一个页面,按F12打开控制台,然后刷新页面并点击播放歌曲,network里面就会有数据包

python爬取QQVIP音乐

 

 

 

3、在控制台选中media,找到下图这样类型的文件,它的request url就是歌曲播放url,如下下图

当然,我们肯定不能每下载一首歌都这样,一是这样很麻烦,二是遇到vip等音乐,你在线都不能播放,你还怎么找到歌曲链接

所以,分析页面是必然的!!!我们首先分析一下这个歌曲播放链接的url

 

https://isure.stream.qqmusic.qq.com/C400002AskAI4LWf5i.m4a?guid=8487932120&vkey=65570474D22ADFAB32FE60DA30EA32CB618422B773A49AE5FA2158C071D4C51931D28B15D823E1BA87BCA837EC09A0FCF8BD9E2763D46B91&uin=0&fromtag=66

我们对这个url进行删减(因为url有些部分都不需要,我们为了看起来更直观要对其进行处理)

 

#精简后url
https://isure.stream.qqmusic.qq.com/C400002AskAI4LWf5i.m4a?guid=8487932120&vkey=65570474D22ADFAB32FE60DA30EA32CB618422B773A49AE5FA2158C071D4C51931D28B15D823E1BA87BCA837EC09A0FCF8BD9E2763D46B91

 

我们大致一看它的url,就知道页面提交用get将参数guid和vkey追加到url地址后面,那么我们就要去找vkey和guid参数是怎么来的

 

guid参数:

你多打开几个歌曲就会发现它的guid都是一样的,所以这个我们就不用管

 

vkey参数:

这个参数难为死我了,我刚开始以为它和网易云音乐一样也是加密一下,然后我就去js文件里面找,找了半天没找到赋值语句,我就纳闷了,以为这是更高级的加密,,,,然后看了半天js,最后终于确定,js和这个没啥关系。。。。。。。

 

之后感觉分析页面分析不动了,上网找了篇博客给了我灵感,虽然那篇博客代码已经过时了,但是它启发了我 “播放歌曲的链接可能不止一个”

于是我又开始找vkey在哪个数据包出现过,如下图

python爬取QQVIP音乐

 

我找到了vkey且对比了一下和之前链接上vkey的值一样,你再仔细看就会发现那个歌曲下载链接就是

https://isure.stream.qqmusic.qq.com/加上purl的值。(我giao!!)

 

然后就要去分析这个数据包的请求头了(呜呜呜~),请求头如下(好长~~~)

 

https://u.y.qq.com/cgi-bin/musics.fcg?-=getplaysongvkey6574047973093009&g_tk=1740745507&sign=zzaztgck8xaqpsxorw45ed952a339dbe91c7990f803cb9a6f1&loginUin=0&hostUin=0&format=json&inCharset=utf8&outCharset=utf-8&notice=0&platform=yqq.json&needNewCode=0&data=%7B%22req_0%22%3A%7B%22module%22%3A%22vkey.GetVkeyServer%22%2C%22method%22%3A%22CgiGetVkey%22%2C%22param%22%3A%7B%22guid%22%3A%228487932120%22%2C%22songmid%22%3A%5B%22003cGaJY10RAsX%22%5D%2C%22songtype%22%3A%5B0%5D%2C%22uin%22%3A%220%22%2C%22loginflag%22%3A1%2C%22platform%22%3A%2220%22%7D%7D%2C%22comm%22%3A%7B%22uin%22%3A0%2C%22format%22%3A%22json%22%2C%22ct%22%3A24%2C%22cv%22%3A0%7D%7D

 

这个时候我就遇到一个坑点(QQ音乐有毒),这么长的链接我们肯定要对其进行删减,好看看哪些参数有用,哪些参数用来混乱我们的视线

但是如果你前面的一段链接改为

 

https://u.y.qq.com/cgi-bin/musicu

 

你就能对很多参数进行删除,就最后一个字母不一样,但是对参数进行删除的时候前面那个链接就基本上参数都不能删除

这让我就很难受,我的访问链接就是 

https://u.y.qq.com/cgi-bin/musics

 这一部分,但是有些人访问链接是

 

https://u.y.qq.com/cgi-bin/musicu

 

 

化简之后链接就变成了

 

https://u.y.qq.com/cgi-bin/musicu.fcg?format=json&data=%7B%22req_0%22%3A%7B%22module%22%3A%22vkey.GetVkeyServer%22%2C%22method%22%3A%22CgiGetVkey%22%2C%22param%22%3A%7B%22guid%22%3A%22358840384%22%2C%22songmid%22%3A%5B%22{}%22%5D%2C%22songtype%22%3A%5B0%5D%2C%22uin%22%3A%221443481947%22%2C%22loginflag%22%3A1%2C%22platform%22%3A%2220%22%7D%7D%2C%22comm%22%3A%7B%22uin%22%3A%2218585073516%22%2C%22format%22%3A%22json%22%2C%22ct%22%3A24%2C%22cv%22%3A0%7D%7D".format(mid值)
            

 

 

 

与其他歌曲的这个链接对比一下就会发现只有songmid的值再改变

我们再去找songmid是什么,疯狂在文件中寻找,结果没有songmid字样,有也是在js中,songmid在js中还多以注释出现。。。

 

之后我在搜索歌曲之后,在歌曲信息的数据包里面发现了mid,然后我把url地址中编码过的mid解码后发现它们一样。。。(牛掰!!!)

下面给一个在多个文件中快速搜索关键子字的方法,如下图:

以搜索“夕阳红为例”

然后再看一下这个数据包的请求头(希望不要麻烦)

 

https://c.y.qq.com/soso/fcgi-bin/client_search_cp?ct=24&qqmusic_ver=1298&new_json=1&remoteplace=txt.yqq.song&searchid=70921863029222715&t=0&aggr=1&cr=1&catZhida=1&lossless=0&flag_qc=0&p=1&n=10&w=%E5%A4%95%E9%98%B3%E7%BA%A2&g_tk_new_20200303=1740745507&g_tk=1740745507&loginUin=0&hostUin=0&format=json&inCharset=utf8&outCharset=utf-8&notice=0&platform=yqq.json&needNewCode=0

 

 

 

删减之后

https://c.y.qq.com/soso/fcgi-bin/client_search_cp?ct=24&qqmusic_ver=1298&new_json=1&remoteplace=txt.yqq.song&searchid=70631360004412645&t=0&aggr=1&cr=1&catZhida=1&lossless=0&flag_qc=0&p=1&n=10&w=%E9%9D%9E%E9%B1%BC&g_tk_new_20200303=5381&g_tk=5381&loginUin=2272463882&hostUin=0&format=json&inCharset=utf8&outCharset=utf-8&notice=0&platform=yqq.json&needNewCode=0

 

通过归纳可以知道n代表搜索到的歌曲显示数目,w是搜索的关键字

所以我们n设定一个值就行,w就运行程序是输入就行

所有问题都解决了(呼~~~~~~~)
