抓包能力有限,分析了一下网易云音乐的一些api接口,但是关于它很多post请求都是加了密,没有弄太明白。之前在知乎看到过一个豆瓣工程师写的教程,但是被投诉删掉了,请问有网友fork了的吗?因为我觉得他写的代码都比较pythonic,符合pep8规范。知乎另外几名大V比如@路人甲虽然经常分享数据,但是很少分享源代码,github也没有公布,公开过的代码我觉得他很多基础的pep8细节都忽略了,而且他的爬虫的效率非常低,比如爬网易10k+评论,在专栏说爬了6个小时之类的很辛苦之类的话,但是看他的代码别提异步了,甚至连多线程/多进程都没有使用,觉得有点水。前面那位大神还是真的有很多干货。

不一定要是python,任意语言都行,各位网友能否分享一些分析网易云音乐api接口的设计博客教程/大型项目

点这里,nodejs版网易云音乐接口。可以看官网的js源码,也可以抓客户端包看接口。现在客户端都采用最新的接口,加密算法不知道。但是官网的weapi接口上面有加密的算法。主要还是要猜字段。很多最老的api也可以用没有加密,但是一些接口被废弃,而且和新接口返回字段也不一样。我上面写的应该够你用的。不够就自己去抓包分析猜字段。基本所有接口都能找到
