背景:
由於所在辦公室網絡限制,筆者每天都使用網絡都要先連接無線網。如下圖,輸入授權用戶信息登錄后才能使用WIFI。
喪心病狂的是該網頁Cookie 過期時間為24小時,所以每天重復以下動作:打開瀏覽器 -> 手動輸入 工號密碼、密碼 -> 點擊“登錄”按鈕。
作為一個懶出天際的程序員,逃避這種重復勞動是必須滴~~

解決方案:
創建一個C# 應用程序,使用WebBrowser控件加載該頁面,模擬鍵盤輸入賬號、密碼,把用戶配置分別賦值給兩個控件,然后調用按鈕的點擊事件。
具體步驟:
1. 打開登錄頁面,按F12查看網頁源碼,可以看到2個輸入控件名分別為 "user", "password",登錄按鈕名為"Login",如下圖:

2. 模擬事件
模擬過程具體又可分為以下4個步驟:
step 1. 讀取配置文件中的 登錄網址、賬號、密碼
step 2. 加載網頁
step 3. 模擬鍵盤操作
step 4. 退出程序
關鍵部分代碼
/// <summary>
/// 加載網頁,模擬登錄動作處理
/// </summary>
private void ProcessLogin()
{
// 驗證配置文件
if (string.IsNullOrEmpty(url))
{
ShowMsg("配置文件錯誤");
return;
}
ShowMsg("正在加載登錄網頁...");
// 加載網頁
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("請確保配置文件中的用戶及登錄密碼准確可用"));
// 網頁元素
HtmlDocument doc = wb.Document;
HtmlElement emuser = doc.GetElementById("user");
SetHtmlValue(emuser, userName);//設置賬戶
HtmlElement empassword = doc.GetElementById("password");
SetHtmlValue(empassword, password);//設置密碼
HtmlElement btn = doc.GetElementById("Login");
InvokeMethod(btn, "click");//調用 登錄按鈕的 Click 事件 提交配置
ShowMsg("完成!");
TimeSpan used = DateTime.Now - begin;//用時
ShowMsg(string.Format("用時: {0}.{1}s" , used.Seconds, used.Milliseconds));
ShowMsg("即將自動退出...");
//啟動計時器,4s 后自動退出當前程序
Timer timer = new Timer();
timer.Interval = 4000;
timer.Tick += new EventHandler(timer_Tick);
timer.Start();
}
catch (Exception ex)
{
ShowMsg(ex.Message);
}
}
編譯應用程序,把快捷方式添加到開機啟動項。這樣開機時就會自動運行程序接入網絡啦!!!
不足之處:
1. 接入網絡成功后網頁會打開如下的頁面,因此模擬登錄成功后也會啟動瀏覽器打開頁面。如果能禁用就更好了。

2. 只能簡單地提示模擬操作完成,調用登錄按鈕事件后沒有檢測是否登錄成功。
關於以上2點不足,如果有人找到解決辦法,就請大膽大意地私信筆者或留言吧 ^_^
適用場景:
本應用演示了如何在客戶端加載頁面並模擬鍵盤鼠標操作,適用於用戶訪問許可配置保存於服務器的登錄網站,那些配置要保存到 Session(會話)的網站訪問 例如 某寶網站登錄 就不適用了,除非繼續使用應用程序中的 WebBrowser 控件操作而不用外部瀏覽器。
