我需要使用带有OAuth的javamail API通过我的应用发送电子邮件 但我需要如何使用我在下面添加的代码。
我的代码：
public class GMailOauthSender {
private Session session;
public SMTPTransport connectToSmtp(String host, int port, String userEmail,
String oauthToken, boolean debug) throws Exception {
Properties props = new Properties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.starttls.required", "true");
props.put("mail.smtp.sasl.enable", "false");
session = Session.getInstance(props);
session.setDebug(debug);
final URLName unusedUrlName = null;
SMTPTransport transport = new SMTPTransport(session, unusedUrlName);
// If the password is non-null, SMTP tries to do AUTH LOGIN.
final String emptyPassword = null;
transport.connect(host, port, userEmail, emptyPassword);
byte[] response = String.format("user=%s\1auth=Bearer %s\1\1", userEmail,
oauthToken).getBytes();
response = BASE64EncoderStream.encode(response);
transport.issueCommand("AUTH XOAUTH2 " + new String(response),
235);
return transport;
}
public synchronized void sendMail(String subject, String body, String user,
String oauthToken, String recipients) {
try {
SMTPTransport smtpTransport = connectToSmtp("smtp.gmail.com",
587,
user,
oauthToken,
true);
MimeMessage message = new MimeMessage(session);
DataHandler handler = new DataHandler(new ByteArrayDataSource(body.getBytes(), "text/plain"));
message.setSender(new InternetAddress(user));
message.setSubject(subject);
message.setDataHandler(handler);
if (recipients.indexOf(',') > 0)
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));
else
message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));
smtpTransport.sendMessage(message, message.getAllRecipients());
} catch (Exception e) {
Log.d("test", e.getMessage());
}
}
}
