一款域名監(jiān)控小工具 Domain(IP)Watcher 實現(xiàn)代碼

更新時間：2011年11月30日 21:01:46 作者：

域名是否正常，網(wǎng)站是否可以正常訪問是很頭痛的問題，怎樣簡單地監(jiān)控域名是否可以正常訪問呢，這里發(fā)布一款域名監(jiān)控小工具：Domain(IP)Watcher

監(jiān)控給定的域名，一旦域名連續(xù)30秒(這是默認值，可以在源碼中修改)無法Ping通，立刻發(fā)郵件到指定郵箱，并發(fā)短信給站長

原理：

　　用后臺線程循環(huán)每隔5秒鐘Ping結定的域名，如果連接5次Ping不通則發(fā)送郵件到給定郵箱。發(fā)短信是通過其他途徑實現(xiàn)的，現(xiàn)在最常用的有兩種方式：

　　一是利用QQ郵箱的手機綁定功能實現(xiàn)收到郵件短信提示

　　二是用www.ifttt.com提供的gmail跟sms服務實現(xiàn)收到郵件發(fā)短信提示

　　本工具用的是第一種。
主要程序：
　　主要是后臺線程ping域名的應用，界面上顯示記錄的是一個richtextbox控件，其他幾個就不說了，代碼如下：
　　窗體后臺程序：

復制代碼代碼如下:

 
public partial class FormMain : Form, IFormWorkThread 
{ 
private delegate void ControlDelegate(string record); 
private WorkThread wtObj; 
ControlDelegate cdObj; 
public FormMain() 
{ 
InitializeComponent(); 
cdObj = SetRecord; 
} 
private void FormMain_Load(object sender, EventArgs e) 
{ 
} 
private void btnBegin_Click(object sender, EventArgs e) 
{ 
if (txtDomain.Text.Trim() == "") 
{ 
MessageBox.Show("Domain(IP) can not be empty!"); 
return; 
} 
if (txtEmail.Text.Trim() == "") 
{ 
MessageBox.Show("Email address can not be empty!"); 
return; 
} 
Regex regex = new Regex(@"\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"); 
if (!regex.IsMatch(txtEmail.Text.Trim())) 
{ 
MessageBox.Show("Email address error!"); 
return; 
} 
wtObj = new WorkThread(this, 0, 3, txtDomain.Text.Trim(), txtEmail.Text.Trim()); 
wtObj.StartShowResult(); 
} 
private void SetRecord(string record) 
{ 
rtxtRecord.AppendText(record); 
if (rtxtRecord.Lines.Length > 5 * 60 * 24 * 7) 
{ 
rtxtRecord.Clear(); 
} 
} 
public void ShowResult(string record) 
{ 
if (rtxtRecord.InvokeRequired) 
{ 
Invoke(cdObj, record); 
} 
else 
{ 
SetRecord(record); 
} 
} 
private void btnEnd_Click(object sender, EventArgs e) 
{ 
if (wtObj != null) 
{ 
wtObj.EndShowResult(); 
} 
} 
private void FormMain_FormClosing(object sender, FormClosingEventArgs e) 
{ 
if (wtObj != null) 
{ 
wtObj.EndShowResult(); 
} 
} 
private void tslblName_Click(object sender, EventArgs e) 
{ 
OpenMyBlog(); 
} 
private void OpenMyBlog() 
{ 
var Info = new System.Diagnostics.ProcessStartInfo("http://artwl.cnblogs.com"); 
System.Diagnostics.Process.Start(Info); 
} 
} 

IFormWorkThread接口：

復制代碼代碼如下:

 
public interface IFormWorkThread 
{ 
void ShowResult(string record); 
} 

WorkThread代碼：

復制代碼代碼如下:

 
public class WorkThread 
{ 
private IFormWorkThread _formWorkThread; 
private Thread thread; 
private int count = 0, maxcount = 5; 
private string domain = ""; 
private string emailaddress = ""; 
public WorkThread(IFormWorkThread formWorkThread,int count,int maxcount,string domain,string email) 
{ 
this.count = count; 
this.maxcount = maxcount; 
this.domain = domain; 
this.emailaddress = email; 
_formWorkThread = formWorkThread; 
} 
private string Ping(string domainname) 
{ 
Ping ping = new Ping(); 
PingReply pr = ping.Send(domainname); 
if (pr.Status == IPStatus.Success) 
{ 
count = count > 0 ? count - 1 : 0; 
} 
else 
{ 
count++; 
if (count > maxcount) 
{ 
EmailHelp.SendEmail(emailaddress, 
string.Format("【 {0} 】不能訪問啦！",domainname), 
string.Format("【 {0} 】不能訪問啦！<br/><br/>【時間】{1}<br/><br/>【Ping】當前ping的結果為：{2}", domainname,DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), pr.Status), 
true); 
count = 0; 
} 
} 
return "【Time】:" + DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + "\t【Domain】:" + domainname + "\t【Status】:" + pr.Status.ToString() + "\t【RoundtripTime】:" + pr.RoundtripTime.ToString() + "\n"; 
} 
public void Deal() 
{ 
while (true) 
{ 
Thread.Sleep(5000); 
string result = Ping(domain); 
_formWorkThread.ShowResult(result); 
} 
} 
public void StartShowResult() 
{ 
thread = new Thread(new ThreadStart(Deal)); 
thread.Name = "TimeThread"; 
thread.Start(); 
} 
public void EndShowResult() 
{ 
thread.Abort(); 
} 
} 

發(fā)郵件代碼：

復制代碼代碼如下:

 
public class EmailHelp 
{ 
public static void SendEmail(string[] emailAddress, string subject, string body, bool ishtml) 
{ 
MailMessage msg = new MailMessage(); 
foreach (string o in emailAddress) 
{ 
msg.To.Add(o); 
} 
msg.Subject = subject;//郵件標題 
msg.Body = body;//郵件內容 
msg.IsBodyHtml = ishtml;//是否是HTML郵件 
Thread sendemail = new Thread(SendReplyEmail); 
sendemail.Start(msg); 
} 
public static void SendEmail(string to, string subject, string body, bool ishtml) 
{ 
SendEmail(new string[] { to }, subject, body, ishtml); 
} 
private static void SendEmail(MailMessage mailMessage) 
{ 
mailMessage.From = new MailAddress("emailaddress", "網(wǎng)站檢測郵件", System.Text.Encoding.UTF8); 
mailMessage.SubjectEncoding = System.Text.Encoding.UTF8;//郵件標題編碼 
mailMessage.BodyEncoding = System.Text.Encoding.UTF8;//郵件內容編碼 
mailMessage.Priority = MailPriority.Normal;//郵件優(yōu)先級 
SmtpClient client = new SmtpClient(); 
//注冊的郵箱和密碼 
client.Credentials = new System.Net.NetworkCredential("emailaddress", "password"); 
client.Port = 25; 
client.Host = "smtp.qq.com"; 
client.EnableSsl = false; 
try 
{ 
client.Send(mailMessage); 
} 
catch (System.Net.Mail.SmtpException ex) 
{ 
//log.Error(ex.Message); 
} 
} 
private static void SendReplyEmail(object model) 
{ 
SendEmail((MailMessage)model); 
} 
}
