背景:
由于所在办公室网络限制,笔者每天都使用网络都要先连接无线网。如下图,输入授权用户信息登录后才能使用wifi。
丧心病狂的是该网页cookie 过期时间为24小时,所以每天重复以下动作:打开浏览器 -> 手动输入 工号密码、密码 -> 点击“登录”按钮。
作为一个懒出天际的程序员,逃避这种重复劳动是必须滴~~
解决方案:
创建一个c# 应用程序,使用webbrowser控件加载该页面,模拟键盘输入账号、密码,把用户配置分别赋值给两个控件,然后调用按钮的点击事件。
具体步骤:
1. 打开登录页面,按f12查看网页源码,可以看到2个输入控件名分别为 "user", "password",登录按钮名为"login",如下图:
2. 模拟事件
模拟过程具体又可分为以下4个步骤:
step 1. 读取配置文件中的 登录网址
step 2. 加载网页
step 3. 模拟键盘操作
step 4. 退出程序

编译应用程序,把快捷方式添加到开机启动项。这样开机时就会自动运行程序接入网络啦!!!
不足之处:
1. 接入网络成功后网页会弹出如下的对话框,因此模拟登录成功后也会启动浏览器打开页面。如果能禁用就更好了。
2. 只能简单地提示模拟操作完成,调用登录按钮事件后没有检测是否登录成功。
关于以上2点不足,如果有人找到解决办法,就请大胆大意地私信笔者或留言吧 ^_^
适用场景:
本应用演示了如何在客户端加载页面并模拟键盘鼠标操作,适用于用户访问许可配置保存于服务器的登录网站,那些配置要保存到 session(会话)的网站访问 例如淘宝登录 就不适用了,除非继续使用应用程序中的 webbrowser 控件操作而不用外部浏览器。
