通过SMTP Gmail Oauth2问题发送邮件

本文介绍了通过SMTP Gmail Oauth2问题发送邮件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我可以通过谷歌示例。

但现在的问题是我无法发送邮件。

com.sun.mail.smtp.SMTPSendFailedException：530- 5.5.1需要验证。请通过 530了解详情，网址为com.sun.mail，网址为support.google/mail/bin/answer.py?answer=14257 f5sm19578172pav.22 。 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）在javax.mail.Transport.send0（Transport.java:195）在javax.mail.Transport.send（Transport.java:124）

首先，我得到无法连接到本地主机，因此我添加了几行代码来执行会话下面到OAuth2Authenticator类，仍然成功地进行了身份验证。但不能发送邮件。

props.put（mail.smtp.host，smtp.gmail。 COM）; props.put（mail.smtp.port，587）;

我使用同一会话对象和SMTP传输对象当我第一次验证成功时，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：我现在明确称为AUTH命令。

解决方案

抱歉的人，答案在这里：我测试过，它的工作原理。短信登录失败 - 通过2步登录（通过手机短信）拒绝通过SMTP发送电子邮件的安全帐户（包括RAW密码和OAuth样式，失败时带有授权错误）。他们会让您创建OAuth令牌，但不会发送电子邮件。

I can authenticated to SMTP by following the google example.

But the problem now is I can't send out the mail. I am getting the following error whenever I try to send out mail.

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

First I am getting can't connect to local host , thus I added a few lines of code to propery of session like below to OAuth2Authenticator class , still authenicated successfully. But can't send out the mail.

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

I am using the same session object and SMTP transport object which will be returned from OAuth2Authenticator class when I first authenticated successfully.

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);

Edited: I now called AUTH command explicitly like that .

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);

but the response still the same.

解决方案

Sorry people, answer is here: Javamail api in android using XOauth I tested, it works.

"SMS style login" failure - Secure accounts with 2 step login (via phone SMS) reject sending email via SMTP (both RAW password & OAuth style, fail with a Authentication error). They will let you create the OAuth token but will not send email.
