我有一个在 Openshift Free (redhat webhotel) 上运行的网络应用程序。
从这个应用程序中，我想通过我的 gmail 帐户使用 javax.mail-api 发送一封电子邮件。
当我尝试从我的开发人员机器运行我的代码尝试时，它在使用 SSL 和不使用 SSL 时都可以正常工作。
但是当我从 openshift 服务器中的 JSP 页面运行它时，它不起作用。我从 gmail 得到这个回复:

下面是没有 SSL 的代码:
public static void sendGmail(String to, String subject, String text) throws AddressException, MessagingException
{
final String SMTP_HOST = "smtp.gmail.com";
final String SMTP_PORT = "587";
final String GMAIL_USERNAME = "xxx@gmail.com";
final String GMAIL_PASSWORD = "xxx";
System.out.println("Process Started");
Properties prop = System.getProperties();
prop.setProperty("mail.smtp.starttls.enable", "true");
prop.setProperty("mail.smtp.host", SMTP_HOST);
prop.setProperty("mail.smtp.user", GMAIL_USERNAME);
prop.setProperty("mail.smtp.password", GMAIL_PASSWORD);
prop.setProperty("mail.smtp.port", SMTP_PORT);
prop.setProperty("mail.smtp.auth", "true");
Session session = Session.getInstance(prop, new Authenticator()
{
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(GMAIL_USERNAME,
GMAIL_PASSWORD);
}
});
session.setDebug(true);
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(GMAIL_USERNAME));
message.addRecipients(Message.RecipientType.TO,InternetAddress.parse(to));
message.setSubject(subject);
message.setText(text);
message.setRecipients(Message.RecipientType.TO,InternetAddress.parse(to));
Transport transport = session.getTransport("smtp");
transport.connect(SMTP_HOST, GMAIL_USERNAME, GMAIL_PASSWORD);
transport.sendMessage(message, message.getAllRecipients());
}
下面是带有 SSL 的代码:
public static void sendGmail(String to, String subject, String text) throws AddressException, MessagingException
{
String host = "smtp.gmail.com";
final String GMAIL_USERNAME = "xxx@gmail.com";
final String GMAIL_PASSWORD = "xxx";
Properties props = new Properties();
props.put("mail.smtps.host", host);
props.put("mail.smtps.auth", "true");
Session session = Session.getInstance(props, null);
session.setDebug(true);
MimeMessage msg = new MimeMessage(session);
msg.setSubject(subject);
msg.setText(text);
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
msg.setFrom(new InternetAddress(username));
msg.setHeader("X-Mailer", "smtpsend");
msg.setSentDate(new Date());
SMTPTransport t = (SMTPTransport)session.getTransport("smtps");
try
{
t.connect(host, username, password);
t.sendMessage(msg, msg.getAllRecipients());
}
finally
{
t.close();
}
}
如您所见，我在 session 的 Debug模式下运行我的尝试，因此以下是我尝试的输出:

你们知道为什么这在我的 openshift 服务器上不起作用吗？

最佳答案
感谢所有帮助。
似乎我需要在我的 gmail 帐户中激活 IMAP。
之后它工作得很好。
