我一直在尝试使用 java 代码从我的 Microsoft Exchange 服务器检索电子邮件。
这是我的代码
Properties properties = new Properties();
properties.put("mail.pop3.host", host);
properties.put("mail.pop3.port", port);
// SSL setting
properties.setProperty("mail.pop3.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
properties.setProperty("mail.pop3.socketFactory.fallback", "false");
properties.setProperty("mail.pop3.socketFactory.port",String.valueOf(port));
properties.setProperty("mail.auth.debug","true");
String pid = "";
Boolean chkFlag = false;
Session session = Session.getInstance(properties);
try {
properties.setProperty("mail.store.protocol", "pop3");
session = Session.getDefaultInstance(properties, null);
Store store = session.getStore("pop3");
System.out.println("host,userName, password"+host +" " +userName + " "+password );
store.connect(host,userName, password);
Folder folderInbox = store.getFolder("Inbox");
folderInbox.open(Folder.READ_WRITE);
System.out.println("bffhb");
String MailsaveDirectory = saveDirectory;
Message[] arrayMessages = folderInbox.search(new FlagTerm(new Flags(
Flags.Flag.SEEN), false));
System.out.println("No. of Unread Messages : " + arrayMessages.length);
for (int i = 0; i < arrayMessages.length; i++) {
System.out.println("msgcnt");
Message message = arrayMessages[i];
Address[] fromAddress = message.getFrom();
Address[] toAddress = message.getRecipients(Message.RecipientType.TO);
String from = fromAddress[0].toString();
String to = toAddress[0].toString();
String subject = message.getSubject();
String queueId = "";
String sentDate = message.getSentDate().toString();
String contentType = message.getContentType();
String messageContent = "";
String attachFiles = "";
MailMht mh = new MailMht();
saveDirectory = MailsaveDirectory + File.separator + "Message-" + (i + 1);
System.out.println("saveDirectory "+saveDirectory);
pid = subject.substring(subject.lastIndexOf(":") + 1);
mh.parseMessages(message, folderInbox, saveDirectory);
if (contentType.contains("multipart")) {
}
if (true) {
File dir = new File(saveDirectory);
System.out.println("dir to be created:" + saveDirectory);
if (dir.exists() == false) {
System.out.println("Creating Dir...");
dir.mkdirs();
System.out.println("Created Dir...");
}
if (contentType.contains("multipart")) {
}
} else {
chkFlag = false;
}
try {
Folder folderI = null;
if (chkFlag) {
folderInbox.setFlags(arrayMessages, new Flags(Flags.Flag.DELETED), true);
folderInbox.close(true);
store.close();
chkFlag = true;
}
} catch (Exception e) {
chkFlag = false;
e.printStackTrace();
folderInbox.close(false);
store.close();
}
}
} catch (MessagingException ex) {
System.out.println("Could not connect to the message store");
ex.printStackTrace();
chkFlag = false;
}
return chkFlag;
}
我已经完成了几乎所有操作，但遇到了身份验证异常
javax.mail.AuthenticationFailedException: [AUTH] Authentication failed.
但是我可以通过live.com网站登录。
有人有摆脱这个问题的建议吗？
最佳答案
是的:您在获取邮件 session 时错过了身份 validator :
Authenticator authenticator=new Authenticator()
{
@Override
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(userName, password);
}
};
properties.setProperty("mail.pop3.auth", "true");
Session session=Session.getInstance(props, authenticator);
顺便说一句，您有两个 session 初始化:删除其中一个。
