前景介绍
爬它！
观察网页url结构
找到XML
破解sign加密参数
import execjsdef 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 signif __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)
获取歌手个数以及页数
# 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}}}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。
获取作者名字以及id号
寻找歌手的歌曲
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。
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
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。
破解参数前先学会"投机取巧"
# C400002wiewH40saXM.m4a?guid=9232644380&vkey=A6F8B706468C0ECFE0F8B6E5E8AAD783D5F852ED0CA66692EB1033B209080BE61208609BEBC2EAF66FA86AC887C8C9F03C02A152E2EF4E24&uin=0&fromtag=66# https://isure.stream.qqmusic.qq.com/C400002wiewH40saXM.m4a?guid=9232644380&vkey=A6F8B706468C0ECFE0F8B6E5E8AAD783D5F852ED0CA66692EB1033B209080BE61208609BEBC2EAF66FA86AC887C8C9F03C02A152E2EF4E24&uin=0&fromtag=66
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}}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
代码优化
因为数据量过大，日常存入数据库
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
防止存入数据库在多线程阶段同时占用，上锁
全部代码
