Flex实现简单的Email发送
?
? 本文主要介绍和实现怎么使用Flex-java来实现Email的发送。这尤其是在做用户回馈的时候需要用到。当然这实现的只要是一个简单的例子。正在执行发送Email功能还是使用java来实现的，Flex只不过提供了数据的输入和封装。使用的原理很简单：Flex-Form <--接受用户输入?? ||?? ||使用RemoteObject方式就用户输入的数据封装成json格式传递到后台java bean?? ||Java Bean()--->执行真正的Email发送----->回馈消息---->Flex-Form使用的界面如下图：
简单实现了用户输入的验证以及Email验证(更详细的可以参考Adobe数据验证)以下是实现的代码：1.后台java处理：【你需要两个jar: mail.jar and activation.jar】
package mail;import javax.mail.*;import javax.mail.internet.*;import java.util.*;import net.sf.json.JSONArray;import net.sf.json.JSONObject;public class SendFlexMail { private static final String SMTP_HOST_NAME = "smtp.163.com"; private static final String SMTP_AUTH_USER = "feixianryexin"; private static final String SMTP_AUTH_PWD = "yourpassword"; // Add List of Email address to who email needs to be sent to private String[] emailList; public String sendFlexMail(String flexMail){ String result=""; JSONArray flexJavaMail = JSONArray.fromObject(flexMail); emailList = new String[2]; JSONObject mailJsonObj = JSONObject.fromObject(flexJavaMail.getString(0)); emailList[0] = mailJsonObj.getString("senderEmail");//send mail to yourself emailList[1] = mailJsonObj.getString("sendToEmail"); String senderName = mailJsonObj.getString("senderName"); String sendToName = mailJsonObj.getString("sendToName"); String senderMail = mailJsonObj.getString("senderEmail"); String emailMessage = mailJsonObj.getString("emailMessage"); String emailTopic = sendToName+":A Letter From Your Friend "+senderName; try{ postMail(emailList,emailTopic, emailMessage,senderMail); result="Congratulations!"; }catch (MessagingException e){ e.printStackTrace(); } return result; } public void postMail( String recipients[ ], String subject, String message , String from) throws MessagingException { boolean debug = false; //Set the host smtp address Properties props = new Properties(); props.put("mail.smtp.host", SMTP_HOST_NAME); props.put("mail.smtp.auth", "true"); Authenticator auth = new SMTPAuthenticator(); Session session = Session.getDefaultInstance(props, auth); session.setDebug(debug); // create a message Message msg = new MimeMessage(session); // set the from and to address InternetAddress addressFrom = new InternetAddress(from); msg.setFrom(addressFrom); InternetAddress[] addressTo = new InternetAddress[recipients.length]; for (int i = 0; i < recipients.length; i++) { addressTo[i] = new InternetAddress(recipients[i]); } msg.setRecipients(Message.RecipientType.TO, addressTo); // Setting the Subject and Content Type msg.setSubject(subject); msg.setContent(message, "text/plain"); Transport.send(msg); } /** * SimpleAuthenticator is used to do simple authentication * when the SMTP server requires it. */ private class SMTPAuthenticator extends javax.mail.Authenticator { public PasswordAuthentication getPasswordAuthentication() { String username = SMTP_AUTH_USER; String password = SMTP_AUTH_PWD; return new PasswordAuthentication(username, password); } }}?2.前台的Flex-Form：??

1 楼 yexin218 2008-06-16 我一直在想，Flex本身有没有发送Email的功能呢？知道的朋友，不妨相告。谢谢 2 楼 hacker47 2008-07-13 FLEX几乎只是客户端的解决方案,AIR中有对数据库操作的相关类库,可以目前支持差强人意,据我所知,FLEX自身还不能发送EMAIL.
