java – Apache Commons Email with attach with base64

我正在尝试通过apache.commons.mail发送一个base64编码的文件,我只是无法找到它应该去的Content-Transfer-Encoding：base64标头.

// Create the email
MultiPartEmail email = new MultiPartEmail();
email.setSmtpPort(587);
email.setDebug(false);
email.setHostName("smtp.gmail.com");
email.setAuthentication("from@gmail.com", "password");
email.setTLS(true);

email.addTo("to@example.com");
email.setFrom("from@example.com");
email.setSubject("subject");

email.attach(new ByteArrayDataSource(
     Base64.encodeBase64(attachFull.getBytes()), "text/plain"), 
     "samplefile.txt", 
     "sample file desc", 
     EmailAttachment.ATTACHMENT
);

而这正是收件人所获得的.

------=_Part_0_614021571.1334210788719
Content-Type: text/plain; charset=Cp1252; name=texto.txt
Content-Transfer-Encoding: quoted-printable
Content-Disposition: attachment; filename=samplefile.txt
Content-Description: sample file desc

我如何指定该文件是Base64编码？

解决方法:

您可以尝试覆盖attach方法并在其中设置Content-Transfer-Encoding标头.默认情况下,框架不会为您设置它或干净地公开MIME bodyPart.
