标签：QQ function 全部歌曲 get pop sign 爬取 length data
前景介绍## 标题
最近小伙伴们听歌的兴趣大涨，网抑云综合症已经遍布各地。
咱们再来抬高一波QQ音乐的热度吧。
爬它！
目标：歌手列表
任务：将A到Z的歌手以及全部页数的歌存到本地和数据库
观察网页url结构
当我们进入网页时发现此时是一个无参数的html网页加载。
寻找我们想要拿到的位置寻找变化，但我们点击A开头的网页跳转时，发现 url 改变了，index 参数应该是首字母，page 参数应该
是页数变化。
这样的话就减少一个找参数的时间啦。
找到XML
还是习惯的点开检查按键，找到首字母的作者提供的XML都需要什么参数，随便点点A-Z发现 XML 有一个请求蹦出来，里面返回
了是个 json 数据集，都点开看看发现找到了每个作者的参数了。成功了一小半！
既然拿到了XML的网站，POST请求是一定的啦，接下来就该分析分析网站所需要的参数都是什么了，大致猜测一下，这么多数
据中sign和data参数有点诡异，不像是正常的参数，加密参数也找到了。
破解sign加密参数
search 找一下sign都在哪里。因为sign应该是个变量，所以说在他后面加个=会查找的更精确一些。找到一个sign参数的位置，这
应该是个JavaScript代码，那就应该是这里面了。点进去！
在JavaScript中找到了 sign 的位置，找到了一个JavaScript调用的网站，我们进去看看是什么代码在里面。
当我们进入网站之后，代码有点乱我们在线格式化一下看看里面是什么。
格式化代码后发现这个里面含有sign参数。这个应该是sign的加密算法，但是其中传了一个参数进入，我们需要了解一下他传了什
么参数，这样我们的sign就出来了。
回到我们调用JavaScript网站的文件中，继续往下看，我们发现 sign 传数值就在他的下部。我们看到了传了个data给这个sign加
密函数，点断点看看data参数是什么。这data值看的好眼熟，这不是一开始很奇怪那个参数data么。原来data弄出来了sign就能给
出来的。
我们继续找刚才的sign。点击下一次跳转我们发现我们找到另一个函数在里面，产生了一种疑惑，这个函数是做什么的，他为什
么会跳向这里。
那我们先看看我们格式化出来的JavaScript到底能不能运行吧。说不定能运行呢。
哦吼，能运行，那就好办了，看看他返回的参数到底是啥，在开头定义一个sign=null，将t返回给sign，再把sign打印出来。这是
刚才的那个跳转过去的方法。
原来如此，那我们将sign调用一下加个()，我们就能发现sign的值就出现了。但我们重复运行发现我们无法得到他的加密值，因为
这些都是一样的。
回想我们刚才说的话，他需要加一个data参数才可以获得加密参数，那好再改一下。
首先我们先下载一个python调用JavaScript的库。pip install PyExecJS
开始写python代码
Python学习交流Q群：906715085###
import execjs
def get_sign(data):
with open('a.js','r',encoding='utf-8')
as f:
text = f.read()
js_data = execjs.compile(text)
sign = js_data.call('get_sign',data)
return sign
if __name__ == "__main__":
data = '{"comm":{"ct":24,"cv":0},"singerList":{"module":"Music.SingerListServer","method":"get_singer_list","param":{"area":-100,"sex":-100,"genre":-100,"index":2,"sin":0,"cur_page":1}}}'
sign = get_sign(data)
print(data)
print(sign)
这是多次调用代码的结果，发现data传入成功了。
获取歌手个数以及页数
个数其实一开始我们已经拿到了，只不过那时候没介绍，仔细的童鞋们应该是看到了总数到底为多少个。我们点开刚才的返回
json结果就能看到total已经给出来当前的个数了。
现在该分析一下data参数，盲猜一通估计page和index都在data里面，要不然这个参数传不上去呀。好的分析一下data到底有啥，
咱拿过来看看。data里面看到了get_singer_list这个应该是主要的东西。
#这个是 A开头 第一页
#{"comm":{"ct":24,"cv":0},"singerList":
{"module":"Music.SingerListServer","method":"get_singer_list","param":{"area":-100,"sex":-100,"genre":-100,"index":1,"sin":0,"cur_page":1}}}
#这个是 B开头 第一页
#{"comm":{"ct":24,"cv":0},"singerList":
{"module":"Music.SingerListServer","method":"get_singer_list","param":{"area":-100,"sex":-100,"genre":-100,"index":2,"sin":0,"cur_page":1}}}
#这个是 B开头 第二页
#{"comm":{"ct":24,"cv":0},"singerList":
{"module":"Music.SingerListServer","method":"get_singer_list","param":{"area":-100,"sex":-100,"genre":-100,"index":2,"sin":80,"cur_page":2}}}
#这个是 B开头 第三页
#{"comm":{"ct":24,"cv":0},"singerList":
{"module":"Music.SingerListServer","method":"get_singer_list","param":{"area":-100,"sex":-100,"genre":-100,"index":2,"sin":160,"cur_page":3}}}
大致我们能分析出来。
•字母的变化在 index 处，也就是A到Z以及后面的# 应该是一共27个在里面，也就是index从1到27我们需要传给他。
•页数的变化在 sin 这里，第一页是0，第二页就是80，第三页是160，冷静分析一下应该是从0开始以80为公差的等差数列。这个
八十应该是代表每一页都含有八十个歌手。
•cur_page应该就是当前页数的意思。那咱们跟着sin一起改变。
那在这我们拿到了总数，加上每一页总共能展示多少，因为多出来的个数需要占一页才可以，我们使用向下取整。
获取作者名字以及id号
我们根据上述写出来爬虫代码后，就可以成功获取 json 的返回值了，在里面我们能看到一个歌手的参数一共有五个，其中
singer_mid 和 singer_name 是我们所需要的。拿到这两个值后可以进入网站下载当前歌手的歌曲。
寻找歌手的歌曲
我们随意点进去一个歌手，进去后寻找XML的网站，我在这里找好了是 getSingerSong 变量。
在这里能获取歌手的每首歌的所能拿到的结果。
我们看一下里面都需要什么参数，好像和上次的差不多哦。sign已经获取到了，data是给定的变量。单纯的data有点变化，但问
题不大。那说明还是能正常访问这个XML的。
data中有点变化的位置就是 singerMid ，这个参数我们在刚才已经获取到了。直接在里面引用一下就好了。begin的参数是一个歌
手歌的页数，num是一页中包括多少歌曲。其实我们传参数可以将这个参数改一下的。把num的值改到一个很大的值，我们就可
以不需要改变begin的参数就能拿到所有的歌曲结果。
我们仔细找一下 json 里面的参数，点击音乐链接进入发现是https://y.qq.com/n/yqq/song/002MQlds19S8qy.html，我们能发现，
在这个歌曲里面的 mid 参数就是每首歌的格式化位置。
寻找下载歌曲的m4a链接
我们点入播放中。寻找里面的m4a链接看看都包含什么参数，发现存在七个链接都是。但我们仔细一看歌曲的大小我们就会发
现，前几个都是有问题的发包，一首歌怎么可能只有几kb呢。毫不犹豫点进去最后一个。
哦吼，这回参数不一样了哦。那我们在重新分析一下下吧别懒了。
我们先查找一下他给出来的一些包，看看能不能找到一个非加密参数出来。
果然，功夫不负有心人。vkey 就不是个加密参数！
破解参数前先学会"投机取巧"
我不知道刚才有没有仔细看这个位置，发现这个也是个很长的字符串，但是他很特殊，特殊到它和m4a的url是一样的。
为了让你们看到，我在这里把这俩写出来，发现到他们差了什么。不变的字符串前缀。。
#C400002wiewH40saXM.m4a?guid=9232644380&vkey=A6F8B706468C0ECFE0F8B6E5E8AAD783D5F852ED0CA66692EB1033B209080BE61208609BEBC2EAF66FA86AC887C8C9F03C02A152E2EF4E24&uin=0&fromtag=66 # https://isure.stream.qqmusic.qq.com/C400002wiewH40saXM.m4a?guid=9232644380&vkey=A6F8B706468C0ECFE0F8B6E5E8AAD783D5F852ED0CA66692EB1033B209080BE61208609BEBC2EAF66FA86AC887C8C9F03C02A152E2EF4E24
那我们先看看vkey到底需要什么参数给进去。其他参数还是都那些，还是差了一个data需要给进去的。咱们分析一下data都需要
给啥吧。
#{"req":{"module":"CDN.SrfCdnDispatchServer","method":"GetCdnDispatch","param":{"guid":"9232644380","calltype":0,"userip":""}},"req_0":{"module":"vkey.GetVkeyServer","method":"CgiGetVkey","param":{"guid":"9232644380","songmid":["002MQlds19S8qy"],"songtype":[0],"uin":"0","loginflag":1,"platform":"20"}},"comm":{"uin":0,"format":"json","ct":24,"cv":0}}
大致分析了一下
•guid是个无用参数。
•songmid 是歌曲的 mid，我们刚才已经获取了
•uin 需要加入一个qq号才可以获取，如果未登陆默认为0
•其他都是定死的参数
m4a文件是一个二进制文件。所以说我们写代码一定要写入二进制文件才可以。
代码优化
1.因为数据量过大，日常存入数据库
2.因为数据下载量大，使用多进程爬取。将A-Z及#各开一个进程
3.防止存入数据库在多线程阶段同时占用，上锁
