Answer 1

试试下面的方法。我想你现在得到了有效的答复。关于有效负载参数仍然有些混乱，因为我无法以正确的方式检查它，因为我无法访问该页面。确保在payload字段中输入email和password。试一试：

import requests
from bs4 import BeautifulSoup

url = 'https://epaper.thehindu.com/'
req_url = 'https://epaper.thehindu.com/Login/ValidateLogin'

with requests.Session() as session:
    res = session.get(url)
    soup = BeautifulSoup(res.text,"lxml")

    payload={
        '__RequestVerificationToken':soup.select_one("[name='__RequestVerificationToken']")['value'],
        'Email':'',  #your email
        'Password':'', #your password
        'hiddenTab':'' 
        }
    r = session.post(req_url,data=payload)
    soup = BeautifulSoup(r.text,"lxml")
    print(soup.title)

您可以尝试检查请求会话cookie是否已更改。登录通常会将一个cookie添加到您的会话cookiejar中，您可以通过编程方式进行检查。在

import requests

target_url = 'url'
target_user = 'user'
target_pw = 'password'

payload = {
    'username': target_user,
    'password': target_pw
}

with requests.Session() as session:
    print(session.cookies)
    r = session.post(target_url, data=payload)
    print(session.cookies)
    session.close()
