怎么提取里面的文字？

用正则表达式取出字符串中{。。。。。。。。。}的内容，

再用json.loads()转成字典，就可以按照字典对象的方式提取字典中的键值了

例子

import re
import json
s = 'window._appState = {"aaa":"文字1","bbb":"文字2"};'
s = re.findall(r'\{.+\}', s, re.S)
dic = json.loads(s[0])
for k,v in dic.items():
    print(k,v)

使用split方法切割，然后对第二部分直接eval，就得到一个词典对象了，你按照词典操作直接取相关的数据即可

假设变量 a 的值是上边那一串

b = a.split('=',1)
c = eval(b[1])

先用正则提取大括号中所有内容，再用json.loads()将json字串转换成python中的字典dic，然后就可以用遍历dic['tittle']的方式获取文本信息。

如有帮助，请点采纳。
