为什么打印的是登录页面的html,而不是登录后首页的html

Question

import requests
import time
import urllib3
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

# 验证码的url地址
new_time = time.time() * 1000
image_url = "https://passport.tuniu.com/ajax/captcha/v/%s" % (new_time)

# 输入你的手机号，密码，验证码
tel=int(input('请输入手机号'))

identify_code=input('请输入验证码')

    'intlCode': '',

# 发起登录请求
res = req.post(url=login_url, headers=headers, data=data, verify=False)
# print(res.content.decode('utf-8'))
html=req.get(url,verify=False)
print(html.content.decode())

Answer 1

应该是自动登录没成功吧。 验证码输入错误， 页面有提示码？

print(res.content.decode('utf-8')
这个内容是啥？
