E-Mail über SMTP senden Gmail Oauth2 Problem
Ich kann mich bei SMTP authentifizieren, indem ich folgedas google beispiel.
Aber das Problem ist jetzt, dass ich die Mail nicht versenden kann. Ich erhalte die folgende Fehlermeldung, wenn ich versuche, eine E-Mail zu versenden.

Zuerst kann ich keine Verbindung zum lokalen Host herstellen, daher habe ich der OAuth2Authenticator-Klasse, die immer noch erfolgreich authentifiziert wurde, ein paar Codezeilen hinzugefügt. Aber ich kann die Mail nicht versenden.
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Ich benutze diedasselbe Sitzungsobjekt und SMTP-Transportobjekt Dies wird von der OAuth2Authenticator-Klasse zurückgegeben, wenn ich mich zum ersten Mal erfolgreich authentifiziert habe.
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);

Bearbeitet: Ich habe jetzt den AUTH-Befehl explizit so aufgerufen.
byte[] response = String.format("user=%s\1auth=Bearer %s\1\1",
emailAddress, accessToken.getToken()).getBytes();
response = BASE64EncoderStream.encode(response);
System.out.println("token check : " + new String(response));
transport.issueCommand("AUTH XOAUTH2 " + new String(response), 235);
aber die antwort ist immer noch die selbe.
