如何通过IMAP和OAuth从hotmail接收电子邮件？

Question

我想通过IMAP从Hotmail接收电子邮件，但我必须通过OAuth进行身份验证。从Microsoft文档，它支持，http://msdn.microsoft.com/en-us/library/dn440163.aspx;

但我不得不知道如何在java中使用它（通过Javamail）。我试图使用谷歌代码示例（正确的电子邮件和access_toket），但失败了。

String email = "stony@hotmail.com"; 
String oauthToken = "XXXXXXXX"; 

initialize(); 

IMAPStore imapStore = connectToImap("imap-mail.outlook.com", 
            993, 
            email, 
            oauthToken, 
            true); 
System.out.println("Successfully authenticated to IMAP.\n"); 


Folder folder = imapStore.getDefaultFolder(); 
folder.open(Folder.READ_ONLY); //****The linke throw exception**** 
for (Message msg : folder.getMessages()) { 
    String subject = msg.getSubject(); 
    System.out.println(":" + subject); 
}

Answer 1

我试验成功！我验证了3件事，

1. 我们可以使用谷歌代码示例收集到Outlook的IMAP。示例代码的链接是https://code.google.com/p/google-mail-oauth2-tools/wiki/JavaSampleCode
2. 必须使用范围wl.imap和wl.offline_access
3. 在我的Hotmail acccount不工作，我甚至无法获得的access_token;但在我使用我的另一个真实帐户后，它可以正常工作。

您正在使用旧版本的JavaMail。如果您使用latest版本，OAuth2 support is built in。
