python处理json时遇到一些特殊的字符

需要把特殊字符替换到才能使用loads方法：

import json
import re
import requests

headers = {
    'authority': 'www.ixigua.com',
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/93.0.4577.82 Safari/537.36',

}

response = requests.get(
    'https://www.ixigua.com/search/100%5E%%5EE5%5E%%5E85%5E%%5E83%5E%%5EE5%5E%%5E90%5E%%5E83%5E%%5EE9%5E%%5E81%5E%%5E8D%5E%%5EE7%5E%%5EBE%5E%%5E8E%5E%%5EE9%5E%%5EA3%5E%%5E9F%5E%%5EE8%5E%%5E8A%5E%%5E82/',
    headers=headers)


pattern = re.compile("_SSR_HYDRATED_DATA=(.*?)</script>")
res = pattern.search(response.text).group(1)
aa = res.replace("\u002F", "/").replace("\u003C", "<").replace("\u003E", ">").replace("\"", "'").replace(
    "undefined", """")

print(json.loads(aa))
