每当下课后打开电脑联网都会跳出这个烦人的页面，每次都要手动登录，太麻烦了（

然后拿起python准备写一个登录脚本

对校园网登录表单进行抓包

我们可以看到登录时通过connect页面提交了一个表单

我们重点去看Request Headers和From Data

然后就可以根据表单信息去模拟post提交操作

    user = ""

    try:

    except BaseException as err:
        print("--------错误--------")
        print(str(err))
        os.system("pause")

最终效果

对之前的代码新加了ini存储功能，现在不用直接在程序中修改账号密码
