[Python] 用python代码扫码登陆QQ空间获取Cookie值,QQ登陆协议,python模拟登陆QQ

前几天研究了下QQ群的几个接口，但是最后面都需要手动输入Cookie才可以运行，然后今天又研究了一下QQ空间的登陆接口，然后就有了下面这些代码，最终的返回值是登录成功的Cookie值。需要手动打开目录下的qrcode.png然后进行扫码。

import re
import time
from random import random

import requests


def hash33(t):
    e = 0
 for i in range(len(t)):
        e += (e << 5) + ord(t[i])
    return 2147483647 & e


def login():
    ss = requests.session()
    url = 'https://ssl.ptlogin2.qq.com/ptqrshow?appid=549000912&e=2&l=M&s=3&d=72&v=4&t=' + str(
        '0.' + str(int(random() * 10000000000000000)))
    response = ss.get(url=url)
    with open('qrcode.png', 'wb') as f:
        f.write(response.content)
    cookie = response.cookies
    headers = requests.utils.dict_from_cookiejar(cookie)
    print(headers)
    while True:
        url = f'https://ssl.ptlogin2.qq.com/ptqrlogin?u1=https%3A%2F%2Fqzs.qzone.qq.com%2Fqzone%2Fv5%2Floginsucc.html'

 html = ss.get(url=url, headers=headers)
        type = re.findall('[u4e00-u9fa5]+', html.text)[0]
        if type == '二维码未失效':
            print(type)
        elif type == '二维码认证中':
            print(type)
        elif type == '登录成功':
            print(type)
            return html.cookies
        else:
            print("二维码已失效，请重新扫码！")
            login()
        time.sleep(2)


if __name__ == '__main__':
    print(login())
