1.前端HTML使用了Jquery，大家如果做演示不要忘記引入Jquery的庫
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head> <title></title> <script src="jquery-1.8.0.min.js" type="text/javascript"></script> <script type="text/javascript"> function sendemail() { var smtp = $('#txtSmtp').val(); var content = $('#txtContent').val(); var title = $('#txtTitle').val(); var from = $('#txtFrom').val(); var to = $('#txtTo').val(); $.post("Handler.ashx", { 'smtp': smtp, 'content': content,'title':title, 'from': from, 'to': to }, function (data) { var n = eval('(' + data + ')'); if (n.success) { alert(n.message); } }); } </script></head><body> <table> <tr><td>smtp:</td> <td><input type="text" id = "txtSmtp" value="Smtp Server" /> </td> </tr> <tr><td>from addr:</td> <td><input type="text" id = "txtFrom" value="xxx@xxx.com" /> </td> </tr> <tr><td>to addr:</td> <td><input type="text" id = "txtTo" value="xxx@xxx.com" /> </td> </tr> <tr><td>title:</td> <td><input type="text" id = "txtTitle" value="title" /> </td> </tr> <tr><td>content:</td> <td><input type="text" id = "txtContent" value="Content" /> </td> </tr> <tr> <td> <input type="button" id="btnSend" value="send" onclick="sendemail()"/> </td> </tr> </table></body></html>2.后臺代碼是一般處理類 ashx，供前臺異步調(diào)用
<%@ WebHandler Language="C#" class="Handler" %>using System;using System.Web;using Utility;public class Handler : IHttpHandler { public void ProcessRequest (HttpContext context) { context.Response.ContentType = "text/plain"; string smtp = HttpContext.Current.Request.Form["smtp"].ToString(); string title = HttpContext.Current.Request.Form["title"].ToString(); string content = HttpContext.Current.Request.Form["content"].ToString(); string from = HttpContext.Current.Request.Form["from"].ToString(); string to = HttpContext.Current.Request.Form["to"].ToString(); try { EmailClient emailClient = new EmailClient(smtp);// localhost::25 emailClient.SendEmail(from, to, title, content); System.Web.Script.Serialization.JavaScriptSerializer jss = new System.Web.Script.Serialization.JavaScriptSerializer(); System.Collections.Generic.Dictionary<string, object> d = new System.Collections.Generic.Dictionary<string, object>(); d.Add("message", "success"); d.Add("success", true); context.Response.Write(jss.Serialize(d)); } catch (Exception ex) { System.Web.Script.Serialization.JavaScriptSerializer jss = new System.Web.Script.Serialization.JavaScriptSerializer(); System.Collections.Generic.Dictionary<string, object> d = new System.Collections.Generic.Dictionary<string, object>(); d.Add("message", ex.Message); d.Add("success", true); context.Response.Write(jss.Serialize(d)); } } public bool IsReusable { get { return false; } }}3.最后是用到的SMTP輔助類
public class EmailClient { private string smtpServer; private string senderAddress; public EmailClient(string smtpServer) { this.smtpServer = smtpServer; this.senderAddress = string.Empty; } public void SendEmail(string fromAddress, string toAddress, string subject, string messageBody) { SmtpClient smtp = new SmtpClient(smtpServer); MailMessage email = new MailMessage(); email.From = new MailAddress(fromAddress); email.To.Add(toAddress); email.Subject = subject; email.Body = messageBody; smtp.Send(email); }}新聞熱點
