我不知道我想的对不对哈，因为这个是get，不是Post,，我就没用json，但是后来还是尝试了一下，如果用json.loads(这个文件)会报错

用import re 正则表达式
re.search(r"=({.*})};",a).group(1)
然后用eval()或是 import json.loads()

最后就当作 dict 操作就可以了

谢谢，用你的r'=({.*});'才行，后面多了右括号，我最先拿到的时候是这样用的
re.search(r'try{var jsondata=({.+})').group(1)这种可不可以

这个我知道，我就是最先不知道怎么剥离出来
我最先想的是re.search(r'try{var jsondata=({.+})').group(1)用这个方法，然后json.loads()剥离出来
但是报错了

哦，我知道，我最先想用json.loads()一直在报错，后来我只是用了({.+})，看来必须用({.+}); 才行
看来最后那个分号不能省，不然要报错

现在我又发现了个问题，这是网址http://www.kuwo.cn/yinyue/5899379?catalog=yueku2016
1楼是我用requests.get()得到的内容，但是下面评论的内容倒是有，但是评论人除了第一个weiT能正常显示意外，其他的都是乱码，是服务器隐藏了吗还是用的编码方式不对,我用的是utf-8，我刚改了下gbk要报错

最先评论,加密了 Access-Control-Allow-Origin: *
Connection: keep-alive
Content-Encoding: gzip
Content-Length: 3258
Content-Type: text/javascript; charset=utf-8
Date: Thu, 19 Apr 2018 14:54:15 GMT

这个要 import gzip 去解密,这个要去百度一下用法,没有了解过

html=gzip.decompress(text).decode("utf-8")

就是说服务器加密了，现在必须解密才能显示出评论人对吧
