老师，你好，帮我看看这个路由器管理界面的ip怎么抓取？
1.通过get请求访问登录页面
http://172.18.21.254/login.htm
Request Headers：
GET /login.htm HTTP/1.1
Host: 172.18.21.254
Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9
Accept-Encoding: gzip, deflate
Accept-Language: zh-CN,zh;q=0.9,en-US;q=0.8,en;q=0.7,zh-TW;q=0.6,und;q=0.5
输入账号密码点击登录
2. post访问页面(不知道为什么是post的根目录的？)
http://172.18.21.254/
Request Headers：
POST / HTTP/1.1
Host: 172.18.21.254
Connection: keep-alive
Content-Length: 71
Pragma: no-cache
Cache-Control: no-cache
Accept: text/plain, */*; q=0.01
X-Requested-With: XMLHttpRequest
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36
Content-Type: application/json; charset=UTF-8
Origin: http://172.18.21.254
Referer: http://172.18.21.254/login.htm
Accept-Encoding: gzip, deflate
Accept-Language: zh-CN,zh;q=0.9,en-US;q=0.8,en;q=0.7,zh-TW;q=0.6,und;q=0.5
Request Payload（这里出现了这个参数，而不是form data）
{"method":"do","login":{"username":"800","password":"42zK46b09TefbwK"}}
3.get http://172.18.21.254/ （这里为什么有发起了个get根目录的请求？）
Request Headers：
GET / HTTP/1.1
Host: 172.18.21.254
Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9
Referer: http://172.18.21.254/login.htm
Accept-Encoding: gzip, deflate
Accept-Language: zh-CN,zh;q=0.9,en-US;q=0.8,en;q=0.7,zh-TW;q=0.6,und;q=0.5
最后我代码运行的结果是一堆报错。。。。
import requests
# requests.session,创建一个保持登录凭据的session实例
login_session = requests.session()
# 1、get请求，获取token信息

# 一定要使用login_session
index_response = login_session.post(url=index_url, headers=header)
print(index_response.text)
