前言#
华北电力大学的校园网认证是向服务器发送一个POST请求，本教程使用Python代码实现这一过程。
准备工作#
-
安装Openwrt系统的路由器或内网服务器
-
Python2/3环境(Openwrt自带)
-
升级pip并安装Python库
pip install --upgrade pip
pip install requests宿舍端登录#
ssh连接Openwrt
vim ./AutoLogin.py写入以下代码：
import requests
import socket
import uuid
import subprocess
import platform
# Network connectivity check function
def check_network_connection(host="baidu.com", timeout=5):
"""
Check if network connection is available by pinging the specified host
Returns True if ping is successful, False otherwise
"""
try:
# Determine ping command based on operating system
system = platform.system().lower()
if system == "windows":
# Windows ping command: ping -n count -w timeout host
cmd = ["ping", "-n", "1", "-w", str(timeout * 1000), host]
else:
# Linux/Mac ping command: ping -c count -W timeout host
cmd = ["ping", "-c", "1", "-W", str(timeout), host]
# Execute ping command with no output to console
with open('nul' if system == "windows" else '/dev/null', 'w') as devnull:
result = subprocess.call(cmd, stdout=devnull, stderr=devnull)
# Return True if ping was successful (return code 0)
return result == 0
except Exception as e:
print("Network check failed: %s" % str(e))
return False
# Portal authentication URL after redirection
url = "http://10.99.0.16/portalAuthAction.do"
wlanuserip = 'xxx.xxx.xxx.xxx'
# mac_address = ':'.join(hex(uuid.getnode())[2:].zfill(12)[i:i + 2] for i in range(0, 12, 2))
mac_address = 'xx:xx:xx:xx:xx:xx'
# Modify to your own username
userid = 'xxxxx'
# Modify to your own password
passwd = 'xxxxx'

# Check network connectivity before attempting login
print("Checking network connectivity...")
if check_network_connection():
print("Network connection is available. No need to perform portal login.")
else:
print("Network connection is not available. Attempting portal login...")
# Send POST request for network login
response = requests.post(url, data, header)
response.encoding = 'GBK'
print("Login response:")
print(response.text)
此代码通过ping检查网络连接状态，若ping超时则触发POST登录
此代码中需修改的有：
-
宿舍网的账号和密码，即
userid和passwd -
url和header中的服务器地址，即在浏览器输入1.1.1.1重定向后的服务器地址 -
已登录过宿舍校园网的终端
wlanuserip和mac_address，以windows笔记本为例：打开浏览器F12开发人员选项—网络—保留日志
手动登录校园网后，找到
portalAuthAction.do，查看其载荷将载荷中的
wlanuserip和mac复制填写到代码中

-
打开浏览器F12开发人员选项—网络—保留日志
-
手动下线校园网后，找到
portalAuthAction.do，查看其载荷 -
将载荷中的
wlanuserip、mac、wlanacIp复制填写到代码中
设置定时任务#
编辑crontab计划任务
crontab -e添加如下代码
*/2 * * * * /usr/bin/python2 /root/AutoLogin.py每两分钟检测一次，断网自动重连
