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http://support.google.com/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）;

解决方案
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.

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

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.
这篇关于通过SMTP Gmail Oauth2问题发送邮件的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
