java - SMTP Gmail Oauth2 の問題でメールを送信

Question

Google の例に従って、SMTP に認証できます。

しかし、今の問題は、メールを送信できないことです。メールを送信しようとすると、次のエラーが表示されます。

com.sun.mail.smtp.SMTPSendFailedException: 530-5.5.1 Authentication Required. Learn more at
530 5.5.1 http://support.google.com/mail/bin/answer.py?answer=14257 f5sm19578172pav.22

    at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:2114)
    at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:1618)
    at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:1119)
    at javax.mail.Transport.send0(Transport.java:195)
    at javax.mail.Transport.send(Transport.java:124)

まず、ローカルホストに接続できないというメッセージが表示されるため、以下のようなセッションのプロパティに数行のコードを OAuth2Authenticator クラスに追加しましたが、それでも正常に認証されました。しかし、メールを送信することはできません。

props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");

最初に認証に成功したときに OAuth2Authenticator クラスから返される同じセッションオブジェクトと SMTP トランスポートオブジェクトを使用しています。

            Message message = new MimeMessage(session);


        message.setFrom(new InternetAddress(msg.getFrom()));
        message.setRecipients(Message.RecipientType.TO,
            InternetAddress.parse(msg.getTo()));
        message.setSubject(msg.getSubject());
        message.setText(msg.getBody());

        transport.send(message);

編集: 私は今、AUTH コマンドを明示的にそのように呼び出しました。

 byte[] response = String.format("user=%s\1auth=Bearer %s\1\1",
                    emailAddress, accessToken.getToken()).getBytes();
            response = BASE64EncoderStream.encode(response);

これは古いスレッドですが、多数のフォーラムを調べた後、これを理解するのに非常に長い時間がかかりました (正しい答えはありませんでした)。上記の回答の多くは、間違ったパスワードを使用することを提案しています

OAuth2 で最新の Google API を使用し、サンプルコード @ http://code.google.com/p/google-mail-oauth2-tools/downloads/detail?name=oauth2-java-sample-20120904も使用している場合.zip&can=2&q=

例外が発生しています com.sun.mail.smtp.SMTPSendFailedException: 530-5.5.1 Authentication Required。詳細については、530 5.5.1 http://support.google.com/mail/bin/answer.py?answer=14257 vo6sm6969236pbc.8 - gsmtpをご覧ください。

問題を解決する手順は次のとおりです

oauth2.pyzip ダウンロードの指示に従って、python を実行します。Argument は、OAuth2コードで使用する必要がある oauthtoken です。

OAuth2Authenticator.connectToSmtp("smtp.googlemail.com", 587, email, oauthToken, true)メソッドを実行してSMTPTransport. メッセージを送信するには:

  //create the message
  //Note that you do need to get the same session object that gets created within the connectToSmtp method.
  MimeMessage message = new MimeMessage(session);
  message.setFrom(new InternetAddress("from@gmail.com"));
  message.addRecipient(Message.RecipientType.TO, new InternetAddress("to@gmail.com"));
  message.setSubject("This is the Subject Line!");
  message.setText("This is actual message");

  //this was the magic line that is needed - for authentication
  transport.issueCommand("AUTH XOAUTH2 " + oauthToken, 235);

  //send the message
  transport.sendMessage(message, message.getAllRecipients());

それはあなたのユーザー名の認証を求めていると思います。

session=Session.getInstance(props,
         new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(fromUsername, password);
            }
          });

次に、上記のセッションをコードで使用します。

上記のグーグルリンクで指定されたコードを使用していませんが、JavaメールAPIを使用してGmailアカウントからメールを送信しています。認証には上記のコードを使用してください

これらを小道具の設定に追加してみてください。

  props.put("mail.smtp.auth", true);
  props.put("mail.smtp.starttls.enable", true);

こんにちは友人、ついに OAUTH を使用してメッセージを送信できるようになりました。私の OAuth2Authenticator ソースを投稿しています。
