自动连接公共WIFI(二):python脚本自动登录

连载：自动连接公共WIFI（一）：连接方法分析

自动登录脚本思路如下：

1. 循环访问www.baidu.com网址，如果成功获取到百度页面，则网络在线。
2. 若1中返回的是WIFI认证页面，则解析该链接，获取我们需要的参数。
3. 拼接认证页面需要的参数，提交WIFI认证，解析返回结果判断是否认证成功。

需要引入requests包，访问baidu页面:

import requests
import time

response = requests.get("http://www.baidu.com")
response.encoding = "utf-8"
if "百度" in response.text:
    # 成功获取到百度首页
    print(time.strftime("%Y-%m-%d-%H:%M:%S", time.localtime()), "网络在线")

如果返回的是WIFI认证页面，解析认证页面链接中的参数：

# wifi认证redirect页面，截取wifi认证url和参数（IP、MAC等）
# redirectUrl = '<script type="text/javascript">location.href="http://10.131.6.1:8080/wsmAuth/iportal/?usermac=34-F7-16-79-XX-XX&userip=10.131.50.166&ssid=FREE%2dWIFI&nasip=10%2e131%2e6%2e1&devType=v7"</script>Authentication is required. Click <a href="http://10.131.6.1:8080/wsmAuth/iportal/?usermac=34-F7-16-79-XX-XX&userip=10.131.50.166&ssid=FREE%2dWIFI&nasip=10%2e131%2e6%2e1&devType=v7">here</a> to open the authentication page.'
redirectUrl = response.text.replace("\n", "")
#使用正则表达式获取参数
matchObjects = re.match(r'.*location.href="(http://.*)wsmAuth.*usermac=(.*)&userip=(.*)&ssid=(.*)&nasip=(.*)&devType=(.*)"</script>', redirectUrl, re.M|re.I)
if matchObjects:
    baseUrl = unquote(matchObjects.group(1))
    usermac = unquote(matchObjects.group(2))
    userip = unquote(matchObjects.group(3))
    ssid = unquote(matchObjects.group(4))
    nasip = unquote(matchObjects.group(5))
    devType = unquote(matchObjects.group(6))

拼接认证参数并提交认证：

# 模拟提交用户名密码登录
authResponse = requests.post(baseUrl+"wsmAuth/login", data={"userName":"135xxxxxxxx","signature":"XXXXXXXX","usermac":usermac,"userip":userip,"ssid":ssid,"nasip":nasip,"devType":devType,"operateType":"7","userAgreement":"1","rabbit":"h3c","templateId":"7","shopid":"1","groupid":"0","authCfgid":"1","ipmAuthType":"1","authPage":"/themeTemplate/1638770462964/auth.xml","onebutton":"0","needWechat":"1"})
if "succurl" in authResponse.text:
    print(time.strftime("%Y-%m-%d-%H:%M:%S", time.localtime()), "WIFI认证成功")
else:
    print(time.strftime("%Y-%m-%d-%H:%M:%S", time.localtime()), "WIFI认证失败", authResponse.status_code, authResponse.text)

完整代码如下：

import requests
from urllib.parse import unquote
import time
import re

while True:
    try:
        sleepTime = 60
        response = requests.get("http://www.baidu.com")
        response.encoding = "utf-8"
        if "百度" in response.text:
            # 成功获取到百度首页
            print(time.strftime("%Y-%m-%d-%H:%M:%S", time.localtime()), "网络在线")
        else:
            print(time.strftime("%Y-%m-%d-%H:%M:%S", time.localtime()), "网络不在线，尝试连接WIFI")
            # wifi认证redirect页面，截取wifi认证url和参数（IP、MAC等）
            # redirectUrl = '<script type="text/javascript">location.href="http://10.131.6.1:8080/wsmAuth/iportal/?usermac=34-F7-16-79-XX-XX&userip=10.131.50.166&ssid=FREE%2dWIFI&nasip=10%2e131%2e6%2e1&devType=v7"</script>Authentication is required.

                    sleepTime = 10
