    近来在做邮件项目时候，我发现as有那么强大的逻辑能力，为什么不用来发送email。发送email时候，我们还可以把压力留给用户，留在前台，那么后台可以减负，在一些需要大量发送信息的系统中，无疑有一定的用处的。

package com.shine.framework.mail.util<br /> {<br /> import flash.events.Event;<br /> import flash.events.ProgressEvent;<br /> import flash.events.SecurityErrorEvent;<br /> import flash.net.Socket;<br /> import flash.utils.ByteArray;</p> <p> import mx.controls.Alert; </p> <p> public class MailUtil<br /> {<br /> private var socket:Socket;<br /> private var smtp:String;<br /> private var _user:String;<br /> private var _pwd:String;<br /> private var _mailFrom:String;<br /> private var _mailTo:String;<br /> private var _subject:String;<br /> private var _content:String;<br /> private var num:int=99;</p> <p> public function MailUtil(smtp:String)<br /> {<br /> initSocket(smtp);<br /> }</p> <p> public function initSocket(smtp:String):void<br /> {<br /> this.smtp = smtp;<br /> if(socket==null || !socket.connected)<br /> {<br /> socket = new Socket();<br /> socket.connect(smtp,25);<br /> socket.addEventListener(Event.CONNECT,ConnectionHandler);<br /> socket.addEventListener(Event.CLOSE,CloseHandler);<br /> socket.addEventListener(ProgressEvent.SOCKET_DATA,ReceiveHandler);<br /> socket.addEventListener(SecurityErrorEvent.SECURITY_ERROR,ErrorHandler);<br /> }<br /> } </p> <p> private function ErrorHandler(evt:SecurityErrorEvent):void<br /> {<br /> Alert.show("error!");<br /> Alert.show(String(evt.text));<br /> } </p> <p> public function ConnectionHandler(evt:Event):void<br /> {<br /> Alert.show("链接成功");<br /> } </p> <p> public function CloseHandler(evt:Event):void<br /> {<br /> Alert.show("已经从服务器断开");<br /> } </p> <p> private function ReceiveHandler(evt:Event):void<br /> {<br /> var msg:String = "";<br /> while(socket.bytesAvailable)<br /> {<br /> msg += socket.readMultiByte(socket.bytesAvailable,"utf8");<br /> }<br /> //Alert.show(msg);<br /> if(num==0){<br /> sendUserName(_user);<br /> num++;<br /> }else if(num==1){<br /> sendPassword(_pwd);<br /> num++;<br /> }else if(num==2){<br /> setFromandTo(_mailFrom,_mailTo);<br /> num++;<br /> }else if(num==3){<br /> sendContent(_subject,_content);<br /> num++;<br /> }else if(num==4){<br /> Alert.show("发送成功");<br /> num++;<br /> }<br /> } </p> <p> public function Send(user:String, pwd:String, mailFrom:String, mailTo:String,subject:String,content:String):void<br /> {<br /> if(socket==null || !socket.connected)<br /> {<br /> initSocket(this.smtp);<br /> } </p> <p> this._user=user;<br /> this._pwd=pwd;<br /> this._mailFrom=mailFrom;<br /> this._mailTo=mailTo;<br /> this._subject=subject;<br /> this._content=content;</p> <p> sendHello();<br /> num=0;<br /> } </p> <p> private function sendHello():void{<br /> sendMessage("HELO mail");<br /> sendMessage("AUTH LOGIN");<br /> } </p> <p> private function sendUserName(user:String):void{<br /> sendMessage(Base64.encode(user));<br /> }</p> <p> private function sendPassword(pwd:String):void{<br /> sendMessage(Base64.encode(pwd));<br /> }</p> <p> private function setFromandTo(mailFrom:String,mailTo:String):void{<br /> sendMessage("MAIL FROM: <"+mailFrom+">");<br /> sendMessage("RCPT TO: <"+mailTo+">");<br /> sendMessage("DATA");<br /> }</p> <p> private function sendContent(subject:String,content:String):void{<br /> sendMessage("Content-Type: text/html");<br /> sendMessage("Subject: "+subject);<br /> sendMessage("");<br /> sendMessage("");<br /> sendMessage(content);<br /> sendMessage(".");<br /> }</p> <p> internal function sendMessage(msg:String):void<br /> {<br /> var message:ByteArray = new ByteArray();<br /> message.writeUTFBytes(msg+"/r/n");<br /> socket.writeBytes(message);<br /> socket.flush();<br /> }<br /> }<br /> } 

调用类

<?xml version="1.0" encoding="utf-8"?><br /> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="{init()}"><br /> <mx:Script><br /> <!--[CDATA[<br /> import com.shine.framework.mail.util.MailUtil;<br /> import com.shine.framework.mail.util.Mail;<br /> import com.shine.framework.mail.util.Base64;<br /> import mx.controls.Alert; </p> <p> private var xmlSocket:Socket;<br /> private var m:MailUtil; </p> <p> private function init():void<br /> {<br /> m = new MailUtil("smtp.163.com");<br /> } </p> <p> public function login():void<br /> {<br /> m.Send("arjick@163.com","password","arjick@163.com","348700730@qq.com","测试4","测试");<br /> }<br /> ]]--><br /> </mx:Script><br /> <mx:VBox width="100%"><br /> <mx:Button id="testEmail" label="测试" click="{login()}" /><br /> </mx:VBox><br /> </mx:Application> 

这个类发送还有有错误，安全策略问题和容错问题
