问题描述

在我的应用程序正在使用smtp.i要附加图像文件mail.how可以附上它发送邮件?我试着在mail.its赠送小图标它。但是没有得到的图像。
请help.thanks提前。
下面是邮寄code和邮件的形象它的外观 -

 公共类MailImageFile扩展javax.mail.Authenticator {公共MailImageFile(){}
公共无效邮件(用户字符串,字符串传递){    属性道具=新特性();
    props.put(mail.smtp.host,smtp.gmail.com);
    props.put(mail.smtp.socketFactory.port,465);
    props.put(mail.smtp.socketFactory.class,javax.net.ssl​​.SSLSocketFactory);
    props.put(mail.smtp.auth,真);
    props.put(mail.smtp.port,465);    会话的会话=作为Session.getDefaultInstance(道具,新javax.mail.Authenticator(){
        受保护的PasswordAut​​hentication的getPasswordAut​​hentication(){
            返回新的PasswordAut​​hentication(用户名,密码);
        }
        });
    尝试{        消息消息=新的MimeMessage(会话);
        message.setFrom(新网际地址(用户名));
        message.setRecipients(Message.RecipientType.TO,InternetAddress.parse(TO));
        message.setSubject(测试题目);
       多部分多部分=新MimeMultipart的();
        MimeBodyPart messageBodyPart =新MimeBodyPart();
        数据源源=新FileDataSource(新文件(Environment.getExternalStorageDirectory()getAbsolutePath()+/ wallpaper.jpg));
        messageBodyPart.setDataHandler(新的DataHandler(源));
        messageBodyPart.setFileName(image.png);
        messageBodyPart.setDisposition(MimeBodyPart.ATTACHMENT);
        messageBodyPart.setHeader(内容ID,&所述;时尚>中);
        multipart.addBodyPart(messageBodyPart);                  message.setContent(多部分);        Transport.send(消息);
    }赶上(MessagingException E){
        抛出新的RuntimeException(E);
    }
}
 }


解决方案

在第二个想法:

使用 javax.mail.util.ByteArrayDataSource:

 多节多部分=新MimeMultipart的();
数据源源=新ByteArrayDataSource(镜像文件,图像/ BMP);//为消息造成的身体部位
MimeBodyPart messageBodyPart =新MimeBodyPart();
messageBodyPart.setContent(嗨......,text / html的;字符集= UTF-8);MimeBodyPart attachPart;
attachPart =新MimeBodyPart();
attachPart .setDataHandler(新的DataHandler(源));
attachPart .setFileName(文件名);multipart.addBodyPart(messageBodyPart);
multipart.addBodyPart(attachPart);message.setContent(多部分);

的构造预计为参数或者一个字节数组或一个InputStream。所以,如果你有在变量BMP位图,你会得到它的ByteArray是这样的:

  ByteArrayOutputStream流=新ByteArrayOutputStream();
bmp.com preSS(Bitmap.Com pressFormat.PNG,100,流);
字节[]的字节数组= stream.toByteArray();

和会使用它在这样的ByteArrayDataSource:

 数据源源=新ByteArrayDataSource(字节数组,图像/ PNG);

in my application i'm sending mail using smtp.i want to attach image file to mail.how can i attach it?i tried it.but not getting image in mail.its giving small icon.please help.thanks in advance.below is mailing code and image of mail how it looks-

 public class MailImageFile extends javax.mail.Authenticator {

public MailImageFile(){

}
public void Mail(String user, String pass) {

    Properties props = new Properties();
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.socketFactory.port", "465");
    props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", "465");

    Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(USERNAME, PASSWORD);
        }
        });
    try {

        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(USERNAME));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(TO));
        message.setSubject("Testing Subject");
       Multipart multipart = new MimeMultipart();


        MimeBodyPart messageBodyPart = new MimeBodyPart();
        DataSource source = new FileDataSource(new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/wallpaper.jpg"));
        messageBodyPart.setDataHandler(new DataHandler(source));
        messageBodyPart.setFileName("image.png");
        messageBodyPart.setDisposition(MimeBodyPart.ATTACHMENT);
        messageBodyPart.setHeader("Content-ID","<vogue>");
        multipart.addBodyPart(messageBodyPart);

                  message.setContent(multipart);

        Transport.send(message);
    } catch (MessagingException e) {
        throw new RuntimeException(e);
    }
}
 }
解决方案

On second thought:

Use javax.mail.util.ByteArrayDataSource:

Multipart multipart = new MimeMultipart();
DataSource source = new ByteArrayDataSource(imageFile, "image/bmp");

// creates body part for the message
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent("Hi...", "text/html; charset=utf-8");

MimeBodyPart attachPart;
attachPart = new MimeBodyPart();
attachPart .setDataHandler(new DataHandler(source));
attachPart .setFileName(filename);

multipart.addBodyPart(messageBodyPart);
multipart.addBodyPart(attachPart);

message.setContent(multipart);

ByteArrayDataSource's constructor expects as parameters either a byte array or an InputStream. So, if you have your Bitmap in the variable bmp you would get it to the byteArray like this:

ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();

and would use it in the ByteArrayDataSource like this:

DataSource source = new ByteArrayDataSource(byteArray, "image/png");
