模拟登陆csdn失败，帮忙看下哪里有问题

Question

从图中得知表单需要哪些数据

下面的两行代码保存cookies

session = requests.Session()
response = session.get(url, headers=headers).content

下面的代码获取表单所需数据

soup = BeautifulSoup(response, "lxml")
# 解析页面获取表单必须的数据
lt = soup.find(attrs={"type": "hidden", "name": "lt"})['value']
execution = soup.find(attrs={"type": "hidden", "name": "execution"})['value']
event_id = soup.find(attrs={"type": "hidden", "name": "_eventId"})['value']

最后还是登录失败

下面是完整代码

import requests
from bs4 import BeautifulSoup

url = 'https://passport.csdn.net/account/login'

headers = {
        "Host": "passport.csdn.net",
        "Referer": "https://passport.csdn.net/account/login",
        "User-Agent": 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.89'
                      ' Safari/537.36',
        "Origin": "https://passport.csdn.net"
    }


def login(username, password):
    captcha_solution = None
    captcha_id = None
    lt = None
    execution = None
    event_id = None
    post_data = {
        "username": username,
        "password": password,
        "rememberMe": "true",
    }
    session = requests.Session()
    response = session.get(url, headers=headers).content
    soup = BeautifulSoup(response, "lxml")
    # 解析页面获取表单必须的数据
    lt = soup.find(attrs={"type": "hidden", "name": "lt"})['value']
    execution = soup.find(attrs={"type": "hidden", "name": "execution"})['value']
    event_id = soup.find(attrs={"type": "hidden", "name": "_eventId"})['value']
    # print(lt)
    # print(execution)
    # print(event_id)
    # 将获取的数据加入表单
    post_data['lt'] = lt
    post_data['execution'] = execution
    post_data['_eventId'] = event_id
    #  所有参数准备完毕 开始登录
    html = session.post(url, data=post_data, headers=headers)
    print(type(html.cookies))
    for key, value in html.cookies.items():
        print(key+": "+value)
    print(html.text)
    # if html.url == 'https://www.csdn.net/':
    #     print(html.text)
    # else:
    #     print('fail')

Answer 1

可以通过捉包得出, 登录url 不是https://passport.csdn.net/acc...
而是这个https://passport.csdn.net/acc...
session.post(url，data=post_data, headers=headers)
中的url 改回 https://passport.csdn.net/acc... 就可以登录
