利用WebBrowser实现自动登入功能

公司内部改革，对考勤方面做出调整，要求实现办公自动化，在OA进行上下班考勤；作为程序员，突发奇想如何实现自动化考勤应用？

需求如下：

可设置考勤地址、用户信息、上下班时间；

根据设置的上下班时间，定时实现自动考勤。

具体实现步骤如下：

窗体界面添加考勤地址、用户信息、上班下班时间、WebBrowser控件；

将WebBrowser地址更改为考勤地址

判断WebBrowser加载完毕后，输入用户、密码信息，点登录进入系统

采用线程阻塞形式，预估登入进入系统时间，再进入考勤菜单进行考勤

代码实现如下：

public partial class Form1 : Form
{
/// <summary>
/// 计数器判断网页是否加载完毕
/// </summary>
int i = 0;
//登入计时器
int j = 0;
//上班计时器
int m = 0;
public Form1()
{
InitializeComponent();
txtUrl.Enabled = false;
txtUser.Enabled = false;
txtPwd.Enabled = false;
tdtstartTime.Enabled = false;
tdtendTime.Enabled = false;

wm = GetWork();
webBrowser.Url = wm.Url;

webBrowser.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBw_DocumentCompleted);
webBrowser.Navigated += new WebBrowserNavigatedEventHandler(webBrowser_Navigated);

}

/// <summary>
/// 用计数器判断界面是否加载完成
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
void webBrowser_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
i++;
}
void webBw_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
i--;
if (0 == i)
{
if (j < 1)
{
Lognin();
j++;
}
if (m < 1 && j > 0)
{
HtmlDocument htmlDoc = webBrowser.Document;
HtmlElement txtMenuCodeQuick = htmlDoc.All["MenuCodeQuick"];
if (txtMenuCodeQuick != null)
{
txtMenuCodeQuick.Focus();
txtMenuCodeQuick.SetAttribute("value", "HR43B");
SendKeys.SendWait("{ENTER}");
m++;
}
}
}
}

/// <summary>
/// 登录
/// </summary>
void Lognin()
{
HtmlDocument htmlDoc = webBrowser.Document;
HtmlElement txtUser = htmlDoc.All["txtUserCodeL"];
txtUser.Focus();
if (txtUser != null)
{
txtUser.SetAttribute("value", wm.User);
}
SendKeys.SendWait(Keys.Tab.ToString());
HtmlElement txtPassword = htmlDoc.GetElementById("txtPasswordL");
if (txtPassword != null)
{
txtPassword.SetAttribute("value", wm.Password);
}
Thread.Sleep(1000);

HtmlElement btnDl = htmlDoc.GetElementById("ctl00$ctl00$c1$CB$btnLogin");
btnDl.InvokeMember("click");
Thread.Sleep(1000);
}

private Workmanger GetWork()
{
Uri u = new Uri(txtUrl.Text);
wm.Url = u;
wm.User = txtUser.Text;
wm.Password = txtPwd.Text;
wm.StratTime = tdtstartTime.Time;
wm.EndTime = tdtendTime.Time;
return wm;
}

//根据指定url地址打开页面
void OpenIE(Uri url)
{
webBrowser.Url = url;
}

private Workmanger wm = new Workmanger();

void EndWork()
{
HtmlDocument htmlDoc = webBrowser.Document;
HtmlElement rtbText = htmlDoc.All["ctl00_ctl00_c1_H1_WsdBasicToolBar1"];
StringBuilder sb = new StringBuilder();
foreach (HtmlElement item in htmlDoc.All)
{
sb.AppendLine(item.Id);
}
File.WriteAllText(@"d:\html.txt", sb.ToString(), Encoding.UTF8);
}
}
