问题:模拟post的参数全部正确,但是返回的结果是错误的,登陆后的页面内容是错误的.

代码:

import requests

import json
import re
from bs4 import BeautifulSoup

def main():

session = requests.session()
headers = {

}

    'client_id': '',
    'code': '',
    'qq': '',

    'hfp': ''

}
login_url = 'https://passport.weibo.cn/signin/login'
username = input('请输入用户名:\n')
password = input('请输入密码：\n')
post_data['username'] = username
post_data['password'] = password
r = session.post(login_url, data=post_data, headers=headers)
cookies=requests.utils.dict_from_cookiejar(session.cookies)
print(cookies)
print(r.content.decode('gbk'))
with open('cookies.json', 'wb') as f:
    # 保存cookies到本地
    f.write((json.dumps(cookies).encode("utf-8")))
    # f.write(json.dumps(cookies))
    print("保存成功")

if name == '__main__':

main()

这个是登陆成功或不成功状态码都是200,然后返回的内容不是登录成功的界面.cookie错误.
求各位大佬解答.或者帮忙小弟测试一下.实在整不明白了.
