java - 通过 SMTP Gmail Oauth2 问题发送邮件

Question

我可以通过以下 the google example 向 SMTP 进行身份验证.

但是现在的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消息。

com.sun.mail.smtp.SMTPSendFailedException: 530-5.5.1 Authentication Required. Learn more at

    at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:1618)

    at javax.mail.Transport.send0(Transport.java:195)
    at javax.mail.Transport.send(Transport.java:124)

首先我无法连接到本地主机，因此我向 OAuth2Authenticator 类的 session 属性添加了几行代码，仍然成功验证。但是发不了邮件。

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

我正在使用相同的 session 对象和 SMTP 传输对象，当我第一次成功通过身份验证时，它们将从 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:我现在像那样显式调用 AUTH 命令。

 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);

但响应还是一样。

Answer 1

抱歉，答案在这里:Javamail api in android using XOauth我测试过，它有效。

“SMS 样式登录”失败 - 使用 2 步登录(通过电话 SMS)的安全帐户拒绝通过 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 token ，但不会发送电子邮件。
