Question

我在非Android环境下使用JavaMail连接GMail时遇到问题。我正在获得OAuth2访问令牌，我认为这是正确的。但是当我尝试使用此访问令牌进行连接时，我得到一个例外：

javax.mail.AuthenticationFailedException：[AUTHENTICATIONFAILED]凭据无效（失败）

对我来说，看起来像Java SASL代码期望有两个返回值（用户名和密码回调？），但只有一个。

我已将问题归结为此代码：

import java.io.IOException;
import java.util.Properties;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Store;

public class TestImap {

    private String userId;
    private String accessToken;

    public TestImap(String[] args) {
        userId = args[0];
        accessToken = args[1];
    }

    public void connectImap()
        throws MessagingException
    {
        System.out.println("Connecting to gmail with IMAP and OAUTH2.");
        Properties props = new Properties();
        props.put("mail.imaps.ssl.enable", "true");
        props.put("mail.imaps.sasl.enable", "true");
        props.put("mail.imaps.sasl.mechanisms", "XOAUTH2");
        props.put("mail.imaps.auth.login.disable", "true");
        props.put("mail.imaps.auth.plain.disable", "true");
        props.put("mail.debug.auth", "true");
        /*
        props.put("mail.imaps.sasl.mechanisms.oauth2.oauthToken",
                    accessToken);
        */
        System.out.println("Creating session...");
        Session session = Session.getInstance(props);
        session.setDebug(true);
        System.out.println("Creating store...");
        Store store = session.getStore("imaps");
        System.out.println("Connecting store...");
        store.connect("imap.gmail.com", 993, userId, accessToken);
        System.out.println("Store connected.  If we get here, things work.");
    }

    public static void main(String[] args) {
        TestImap test = new TestImap(args);
        try {
            test.connectImap();
        } catch (Throwable e) {
            System.out.println("Died throwing an exception: ");
            e.printStackTrace();
        }
    }

}

运行时，会给出以下输出：

这是JavaMail 1.5.3。我用谷歌搜索了这个问题，到目前为止我发现的大部分答案已经足够陈旧，我很确定它们早于JavaMail支持google本地化。

非常感谢任何帮助。感谢。
