javaMail不适用于OAuth gmail发送电子邮件 [英] javaMail not working with OAuth gmail send email

问题描述

javaMail:使用Google oauth发送邮件导致javax.mail.AuthenticationFailedException.

javaMail: send mail using google oauth caused javax.mail.AuthenticationFailedException.

Properties props = new Properties();
props.put("mail.smtp.ssl.enable", "true"); // required for Gmail
props.put("mail.smtp.auth.mechanisms", "XOAUTH2");

Session session = Session.getInstance(props);
Transport transport = session.getTransport("smtps");
transport.connect("smtp.gmail.com", 465, [e-mail], oauth_access_token);

在运行代码之前大约20秒，oauth访问令牌是有效的，只是刷新了.

The oauth access token is valid, just refreshed, about 20 seconds before running the code.

错误:

javax.mail.AuthenticationFailedException: 535-5.7.8 Username and Password not accepted. Learn more at
535 5.7.8  https://support.google.com/mail/?p=BadCredentials s136sm158338qka.106 - gsmtp

        at com.sun.mail.smtp.SMTPTransport$Authenticator.authenticate(SMTPTransport.java:965)

        at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:780)
        at javax.mail.Service.connect(Service.java:366)

从日志记录来看，似乎auth使用的是用户名/密码，而不是OAUTH.指南: https://javaee.github.io/javamail/OAuth2

From the logging, it seems that auth is using username/password, not OAUTH. guide: https://javaee.github.io/javamail/OAuth2

推荐答案

尝试以下代码:

        Properties props = new Properties()
            props.setProperty("mail.smtp.host", "smtp.gmail.com")
            props.setProperty("mail.smtp.port", "587")
            props.put("mail.smtp.auth","true")
            props.put("mail.smtp.starttls.enable", "true")
            props.put("mail.smtp.starttls.required", "true")
            props.put("mail.smtp.auth.mechanisms", "XOAUTH2")
            props.put("mail.smtp.auth.login.disable", "true")
            props.put("mail.smtp.auth.plain.disable", "true")
            props.put("mail.smtp.auth.ntlm.disable", "true")
            props.put("mail.debug", "true")
            props.put("mail.debug.auth", "true")
            Session session = Session.getInstance(props)
            String emptyPassword = ""
            final URLName unusedUrlName = null
            SMTPTransport transport = new SMTPTransport(session, unusedUrlName)
            transport.connect("smtp.gmail.com", googleEmail, googleAccessToken)\
            Multipart multipart = new MimeMultipart()
            BodyPart messageBodyPart = new MimeBodyPart()
            def from = googleEmail
            def to = "[e-mail]"
            def subj = "TestOath2Gmail"
            def body = "TTT"
            message.setFrom(new InternetAddress(googleEmail))
            message.addRecipient(javax.mail.Message.RecipientType.TO, new InternetAddress(to))
            Date sentDate = new Date()
            message.setSentDate(sentDate)
            message.setSubject(subj)
            messageBodyPart.setContent(body, "text/html")
            multipart.addBodyPart(messageBodyPart)
            message.setContent(multipart)
            transport.send(message)
