第一次 储存cookie

import requests,json

s = requests.session()
a = s.get("https://www.baidu.com")
cookies = requests.utils.dict_from_cookiejar(s.cookies)
with open(".\cook.txt", "w") as fp:
    json.dump(cookies, fp)

第二次 读取使用cookie会错报    TypeError: string indices must be integers

import requests,json

f = open('./cook.txt', 'r',encoding='UTF-8')
cookies=f.read()
f.close()
s = requests.session() 
a = s.get("https://www.baidu.com",cookies=cookies)

a = s.get("https://www.baidu.com",cookies=eval(cookies))
这样试一下  那个read出来的是字符串  不是json

import requests
import json

with open("./cook.txt", "r") as fp:
    cookies = json.load(fp)

s = requests.session() 
a = s.get("https://www.baidu.com",cookies=cookies)
