Python 使用请求登录-不捕获重定向

我正在尝试学习请求模块，并练习登录网站，但由于某些原因，该模块无法工作，我无法登录

import requests
import sys

param1 = sys.argv[1]
param2 = sys.argv[2]

url2 = 'https://myhpgas.in/myHPGas/Login.aspx'

with requests.Session() as s:
    s.get(url2)
    print(r.headers)
    payload = {'ctl00$ContentPlaceHolder1$txtUserNameEmail': param1,
               'ctl00$ContentPlaceHolder1$txtPassword': param2}
    p = s.post(url2, data=payload, headers=headers)
    p.raise_for_status()
    r = s.get('https://myhpgas.in/myHPGas/HPGas/User/ConsumerConsole.aspx')
    print(r.text)

有人能告诉我这里缺少什么吗？

我能够解析GET响应，然后从html源中提取动态值，然后在POST请求中发布它们，这就解决了我的问题。

您需要在登录api代码中将

状态代码设置为
302
，您的
http post请求
将始终返回
200
，因为它只检查响应。请详细说明如何执行。我想我使用的网站只返回302，我检查这是firefox，post返回302。我得到
HTTP/1.1200 OK
作为响应您是否能够登录到该网站并查看欢迎信息？
