使用微軟國際版的看：javamail微軟郵箱imap協(xié)議使用oauth2.0認(rèn)證–微軟郵箱國際版

一、賬號授權(quán)

imap協(xié)議使用oauth2.0身份認(rèn)證，必須先對帳號進(jìn)行授權(quán)，授權(quán)方式可以看我之前的文章：微軟郵箱oath2協(xié)議下，使用imap協(xié)議時對賬號授權(quán)，如果不進(jìn)行授權(quán)，即使認(rèn)證通過了，但是獲取郵件相關(guān)文件夾時，會報錯：A3 BAD User is authenticated but not connected.;
具體報錯如下：

二、直接上代碼

                token = map.get("access_token");
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            postMethod.releaseConnection();
        }

        try {
            String protocol = "imap";
            int port = 993;

            properties.setProperty("mail." + protocol + ".ssl.enable", "true");
            properties.setProperty("mail." + protocol + ".auth.mechanisms", "XOAUTH2");

            Session session = Session.getInstance(properties);
            //session.setDebug(true);

            Store store = session.getStore(protocol);

            store.connect(host, port, mailAddress, token);
            System.out.println("測試通過");
            Folder inboxFolder = getInboxFolder(store);
            Message[] messages = inboxFolder.getMessages();
            System.out.println(messages.length);

        } catch (Exception ex) {
            ex.printStackTrace();
            System.out.println("不通過");
        }

    }

    public static Folder getInboxFolder(Store store) throws Exception {
        Folder folder = null;
        if(store != null) {
            folder = store.getDefaultFolder();
            folder = folder.getFolder("INBOX");
            if(!folder.isOpen()) {
                folder.open(Folder.READ_ONLY);
            }
        }
        return folder;
    }

}

其實和國際版的比較，也就scope 、url 還有host 這三個參數(shù)不一樣，其他的都一樣文章來源地址http://www.zghlxwxcb.cn/news/detail-848479.html
