通过SMTP Gmail Oauth2问题发送邮件

时间：2012-12-28 04:08:56

标签： java smtp gmail smtp-auth google-oauth

我可以通过the google example来验证SMTP。

但现在问题是我无法发送邮件。每当我尝试发送邮件时，我都会收到以下错误。

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.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)

首先我得到的是无法连接到本地主机，因此我添加了几行代码以便像下面的OAuth2Authenticator类一样进行会话，仍然成功地进行了身份验证。但不能发出邮件。

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

我正在使用相同的会话对象和SMTP传输对象，当我第一次成功验证时，它将从OAuth2Authenticator类返回。

            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);

编辑： 我现在明确地称之为AUTH命令。<​​/ p> 

 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);

但反应仍然相同。

6 个答案:

答案 0 :(得分：2)

对不起的人，回答在这里：Javamail api in android using XOauth我测试过，它有效。

“短信样式登录”失败 - 通过2步登录（通过电话短信）安全帐户拒绝通过SMTP发送电子邮件（RAW密码和OAuth样式，失败并出现身份验证错误）。他们会让您创建OAuth令牌，但不会发送电子邮件。

答案 1 :(得分：0)

您只需要进行身份验证即可。按照这个例子，它也使用gmail： http://www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/

答案 2 :(得分：0)

这是一个老线程，但是经过很多论坛后我花了很长时间来解决这个问题（并且他们都没有得到正确的答案）所以如果有人帮助我会发布它。上面的许多答案建议使用不正确的密码

如果您使用最新的Google API与OAuth2，并使用示例代码@ http://code.google.com/p/google-mail-oauth2-tools/downloads/detail?name=oauth2-java-sample-20120904.zip&can=2&q=

并且正在获得例外 com.sun.mail.smtp.SMTPSendFailedException: 530-5.5.1 Authentication Required。了解更多信息 530 5.5.1 http://support.google.com/mail/bin/answer.py?answer=14257 vo6sm6969236pbc.8 - gsmtp

以下是解决问题的步骤

完全按照zip下载中的说明运行python oauth2.py。 OAuth2参数是您必须在代码中使用的oauthtoken。

运行OAuth2Authenticator.connectToSmtp("smtp.googlemail.com", 587, email, oauthToken, true)方法后获取SMTPTransport。发送消息：

  //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());

答案 3 :(得分：-1)

我认为这是要求验证您的用户名。 

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

然后在代码中使用上面的会话。

我没有使用你提到的google链接中指定的代码，但是我使用java mail api从我的gmail帐户发送电子邮件。使用上面的代码进行身份验证

答案 4 :(得分：-1)

尝试将这些添加到您的道具配置.. 

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

答案 5 :(得分：-1)

嗨朋友终于我能够使用OAUTH发送消息，发布我的OAuth2Authenticator来源，
