C# winform 模擬鍵盤輸入自動(dòng)接入訪問(wèn)網(wǎng)絡(luò)的實(shí)例

 更新時(shí)間:2016年11月17日 11:03:15   作者:vicky liang  
本篇文章主要介紹了C# winform 模擬鍵盤輸入自動(dòng)接入訪問(wèn)網(wǎng)絡(luò),有興趣的可以了解一下。

背景:

由于所在辦公室網(wǎng)絡(luò)限制,筆者每天都使用網(wǎng)絡(luò)都要先連接無(wú)線網(wǎng)。如下圖,輸入授權(quán)用戶信息登錄后才能使用WIFI。

喪心病狂的是該網(wǎng)頁(yè)Cookie 過(guò)期時(shí)間為24小時(shí),所以每天重復(fù)以下動(dòng)作:打開瀏覽器 -> 手動(dòng)輸入 工號(hào)密碼、密碼 -> 點(diǎn)擊“登錄”按鈕。

作為一個(gè)懶出天際的程序員,逃避這種重復(fù)勞動(dòng)是必須滴~~

解決方案:

創(chuàng)建一個(gè)C# 應(yīng)用程序,使用WebBrowser控件加載該頁(yè)面,模擬鍵盤輸入賬號(hào)、密碼,把用戶配置分別賦值給兩個(gè)控件,然后調(diào)用按鈕的點(diǎn)擊事件。

具體步驟:

1. 打開登錄頁(yè)面,按F12查看網(wǎng)頁(yè)源碼,可以看到2個(gè)輸入控件名分別為 "user", "password",登錄按鈕名為"Login",如下圖:

2. 模擬事件

模擬過(guò)程具體又可分為以下4個(gè)步驟:

step 1. 讀取配置文件中的 登錄網(wǎng)址

step 2. 加載網(wǎng)頁(yè)

step 3. 模擬鍵盤操作

step 4. 退出程序

關(guān)鍵部分代碼

/// <summary>
/// 加載網(wǎng)頁(yè),模擬登錄動(dòng)作處理
/// </summary>
private void ProcessLogin()
{
  // 驗(yàn)證配置文件
  if (string.IsNullOrEmpty(url))
  {
    ShowMsg("配置文件錯(cuò)誤");
    return;
  }
 
  ShowMsg("正在加載登錄網(wǎng)頁(yè)...");
  // 加載網(wǎng)頁(yè)
  webBrowser1.Navigate(url);
  //等待瀏覽器控件加載完成
  while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)
  {
    Application.DoEvents();
  }
  ShowMsg("加載完畢!");
  //模擬登錄事件
  LoginSimulation(webBrowser1);
}
//模擬登錄事件
private void LoginSimulation(WebBrowser wb)
{
  try
  {
    ShowMsg(string.Format("賬戶名:[{0}],輸入賬戶密碼...", userName));
    ShowMsg(string.Format("請(qǐng)確保配置文件中的用戶及登錄密碼準(zhǔn)確可用"));
 
    // 網(wǎng)頁(yè)元素
    HtmlDocument doc = wb.Document;
    HtmlElement emuser = doc.GetElementById("user");
    SetHtmlValue(emuser, userName);//設(shè)置賬戶
    HtmlElement empassword = doc.GetElementById("password");
    SetHtmlValue(empassword, password);//設(shè)置密碼
    HtmlElement btn = doc.GetElementById("Login");
    InvokeMethod(btn, "click");//調(diào)用 登錄按鈕的 Click 事件 提交配置
 
    ShowMsg("完成!");
    TimeSpan used = DateTime.Now - begin;//用時(shí)
    ShowMsg(string.Format("用時(shí): {0}.{1}s" , used.Seconds, used.Milliseconds));
    ShowMsg("即將自動(dòng)退出...");
 
    //啟動(dòng)計(jì)時(shí)器,4s 后自動(dòng)退出當(dāng)前程序
    Timer timer = new Timer();
    timer.Interval = 4000;
    timer.Tick += new EventHandler(timer_Tick);
    timer.Start();
  }
  catch (Exception ex)
  {
    ShowMsg(ex.Message);
  }
}

 編譯應(yīng)用程序,把快捷方式添加到開機(jī)啟動(dòng)項(xiàng)。這樣開機(jī)時(shí)就會(huì)自動(dòng)運(yùn)行程序接入網(wǎng)絡(luò)啦?。?!

不足之處:

1. 接入網(wǎng)絡(luò)成功后網(wǎng)頁(yè)會(huì)彈出如下的對(duì)話框,因此模擬登錄成功后也會(huì)啟動(dòng)瀏覽器打開頁(yè)面。如果能禁用就更好了。

2. 只能簡(jiǎn)單地提示模擬操作完成,調(diào)用登錄按鈕事件后沒(méi)有檢測(cè)是否登錄成功。

關(guān)于以上2點(diǎn)不足,如果有人找到解決辦法,就請(qǐng)大膽大意地私信筆者或留言吧 ^_^

適用場(chǎng)景:

本應(yīng)用演示了如何在客戶端加載頁(yè)面并模擬鍵盤鼠標(biāo)操作,適用于用戶訪問(wèn)許可配置保存于服務(wù)器的登錄網(wǎng)站,那些配置要保存到 Session(會(huì)話)的網(wǎng)站訪問(wèn) 例如淘寶登錄 就不適用了,除非繼續(xù)使用應(yīng)用程序中的 WebBrowser 控件操作而不用外部瀏覽器。
