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

我可以按照 谷歌示例.

但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.

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.

首先我无法连接到本地主机，因此我在会话的属性中添加了几行代码，如下面的 OAuth2Authenticator 类，仍然成功验证.但发不出邮件.

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");

我正在使用相同的会话对象和 SMTP 传输对象，当我第一次成功进行身份验证时，它将从 OAuth2Authenticator 类返回.

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);

我现在像这样明确地调用 AUTH 命令.

Edited: I now called AUTH command explicitly like that .

byte[] response = String.format("user=%s1auth=Bearer %s11", emailAddress, accessToken.getToken()).getBytes(); response = BASE64EncoderStream.encode(response); System.out.println("token check : " + new String(response)); transport.issueCommand("AUTH XOAUTH2 " + new String(response), 235);

但反应还是一样.

推荐答案

对不起，答案在这里:Javamail api in android using XOauth 我测试过，它可以工作.

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

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).他们将允许您创建 OAuth 令牌，但不会发送电子邮件.

"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.
