Question

我编写了以下java代码来阅读收件箱消息：

let tbc = self.storyboard!.instantiateViewController(withIdentifier: "MyTabController") as! UITabBarController
        tbc.selectedIndex = 1

        // Suppose your viewcontroller is at tab bar first index.
        let transportJourneyViewControllerOBJ = tbc.viewControllers?[0] as! ViewController
        transportJourneyViewControllerOBJ.strValue = "Testvalue"
        self.present(tbc, animated: true, completion: nil)

我在行

上收到AuthenticationFailed Exception

public void readEMail() {
    try {
        String user = "<<MY_EMAIL_ADDRESS>>";
        String password = "<<MY_PASSWORD>>";

        Properties properties = System.getProperties();
        Session session = Session.getDefaultInstance(properties);

        Store store = session.getStore("pop3");
        store.connect(MY_HOST_NAME, user, password);

        Folder folder = store.getFolder("inbox");
        if (!folder.exists()) {
            System.out.println("inbox not found");
            System.exit(0);
        }
        folder.open(Folder.READ);

        Message[] msg = folder.getMessages();
        for (int i = 0; i < msg.length; i++) {
            String from = InternetAddress.toString(msg[i].getFrom());
            if (from != null) {
                System.out.println("From: " + from);
            }
            String replyTo = InternetAddress.toString(msg[i].getReplyTo());
            if (replyTo != null) {
                System.out.println("Reply-to: " + replyTo);
            }
            String to = InternetAddress.toString(msg[i].getRecipients(Message.RecipientType.TO));
            if (to != null) {
                System.out.println("To: " + to);
            }
            String subject = msg[i].getSubject();
            if (subject != null) {
                System.out.println("Subject: " + subject);
            }
            Date sent = msg[i].getSentDate();
            if (sent != null) {
                System.out.println("Sent: " + sent);
            }
            System.out.println("Message : ");
            System.out.println(msg[i].getContent());
        }
        folder.close(true);
        store.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

如果我将我的提供者从pop3更改为imap，我会得到异常store.connect(MY_HOST_NAME,user,password);

修改

使用IMAP并将debug设置为true时，将在控制台中打印以下内容：

javax.mail.AuthenticationFailedException: AUTHENTICATE failed

使用POP3时，输出为：
