我想使用带有2个附件的Javamail发送电子邮件。其中一个是json文件,另一个是txt文件(logcat.txt)。 logcat.txt的大小约为1mb。
如果我的代码中包含addAttachment(multipart,reportPath,"logcat.txt");
,它不会发送任何电子邮件。如果我删除addAttachment(multipart,reportPath,"logcat.txt");
,它可以工作。
当json文件变大时,在大约500kb的一点上,它都不发送。
我的代码:
public synchronized void sendReport(String subject, String body, String filepath, String filename, String reportPath, String sender, String recipients){
try {
Multipart multipart = new MimeMultipart("mixed"); //try adding "mixed" here as well but it doesn't work
MimeMessage message = new MimeMessage(session);
message.setSender(new InternetAddress(sender));
message.setSubject(subject);
//body
BodyPart messageBodyPart2 = new MimeBodyPart();
messageBodyPart2.setText(body);
Log.d(TAG, "sendReport: " + reportPath);
//this prints sendReport: /storage/emulated/0/Android/data/**app package name**/files/LOG-1472631395.json
Log.d(TAG, "sendReport: " + filepath);
//sendReport: /storage/emulated/0/Android/data/**app package name**/files/logcat.txt
addAttachment(multipart,filepath,filename);
addAttachment(multipart,reportPath,"logcat.txt");
multipart.addBodyPart(messageBodyPart2);
message.setContent(multipart);
if (recipients.indexOf(',') > 0)
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));
else
message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));
Transport.send(message);
} catch (Exception e) {
e.printStackTrace();
}
}
private static void addAttachment(Multipart multipart, String filepath, String filename) throws MessagingException
{
DataSource source = new FileDataSource(filepath);
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
multipart.addBodyPart(messageBodyPart);
}
我还使用另一种方法发送附件,但是它也不起作用:
private static void addAttachment(Multipart multipart, String filepath, String filename) throws Exception
{
MimeBodyPart mimeBodyPart = new MimeBodyPart();
mimeBodyPart.attachFile(filepath);
mimeBodyPart.setFileName(filename);
multipart.addBodyPart(mimeBodyPart);
}
有谁知道如何解决这个问题?先感谢您。
最佳答案
//In this list set the path from the different files you want to attach
String[] attachments;
Multipart multipart = new MimeMultipart();
//Add attachments
if(attachments != null && attachments.length > 0) {
for (String str : attachments) {
MimeBodyPart messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(str);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(source.getName());
multipart.addBodyPart(messageBodyPart);
}
}
message.setContent(multipart);
我上传大型文件没有问题,您可以尝试以下代码。
