我正在尝试使用 JavaMail 通过 IMAP 连接到 gmail

这是我在做什么的代码片段

public class OAuth2Authenticator {
private static final Logger logger = Logger
        .getLogger(OAuth2Authenticator.class.getName());
private static Session mSession;

public static final class OAuth2Provider extends Provider {
    private static final long serialVersionUID = 1L;

    public OAuth2Provider() {
        super("Google OAuth2 Provider", 1.0,
                "Provides the XOAUTH2 SASL Mechanism");
        put("SaslClientFactory.XOAUTH2",
                "org.scribe.examples.OAuth2SaslClientFactory");
    }
}

public static void initialize() {
    Security.addProvider(new OAuth2Provider());
}

public static IMAPStore connectToImap(String host, int port,
        String userEmail, String oauthToken, boolean debug)
        throws Exception {
    Properties props = new Properties();
    props.put("mail.imaps.sasl.enable", "true");
    props.put("mail.imaps.sasl.mechanisms", "XOAUTH2");
    props.put(OAuth2SaslClientFactory.OAUTH_TOKEN_PROP, oauthToken);
    Session session = Session.getInstance(props);
    session.setDebug(debug);

    final URLName unusedUrlName = null;
    IMAPSSLStore store = new IMAPSSLStore(session, unusedUrlName);
    final String emptyPassword = "";
    store.connect(host, port, userEmail, emptyPassword);
    return store;
}



public static synchronized void testImap(String user, String oauthToken) {
    try {

        initialize();



        IMAPStore imapStore = connectToImap("imap.gmail.com", 993, user,
                oauthToken, true);

    } catch (Exception e) {

        System.out.println("Failed");
        e.printStackTrace();
    }

}


    public static void main (String[] args){

        String username="username@gmail.com";
        String oauthToken=GoogleExample.getOAuthCode();// explained below
        testImap(username, oauthToken);
    }
}

为了获得 OauthToken，我正在使用这样的抄写员

private static final String NETWORK_NAME = "Google";
  private static final String AUTHORIZE_URL = "https://www.google.com/accounts/OAuthAuthorizeToken?oauth_token=";
  private static final String PROTECTED_RESOURCE_URL = "https://mail.google.com/mail/feed/atom";
  private static final String SCOPE = "https://mail.google.com/mail"; 


  public static String getOAuthCode(){

      OAuthService service = new ServiceBuilder()
      .provider(GoogleApi.class)
      .apiKey("anonymous")
      .apiSecret("anonymous")
      .scope(SCOPE)
      .build();
      Scanner in =new Scanner(System.in);
      System.out.println("=== " + NETWORK_NAME + "'s OAuth Workflow ===");
      System.out.println();

      //Obtain Request token
      System.out.println("Fetching request token");
      Token requestToken = service.getRequestToken();
      System.out.println("The request token"+requestToken);
      System.out.println("Authorizing Scribe");
      System.out.println();
      System.out.println(AUTHORIZE_URL + requestToken.getToken());
      System.out.println("And paste the verifier here");
      System.out.print(">>");
      Verifier verifier = new Verifier(in.nextLine());
      System.out.println();

      System.out.println("Trading the Request Token for an Access Token...");
        Token accessToken = service.getAccessToken(requestToken, verifier);
        System.out.println("Got the Access Token!");
        System.out.println("(if your curious it looks like this: " + accessToken + " )");
        System.out.println();

      return accessToken.getToken();



  }

这是我运行程序时得到的调试日志

猜测一下，你的令牌是坏的。

1/hKn9r0lSf1QWp0ESgn7J18PDnpE80buxvjcaGRLm9wM , -SGAHMqlD6kaxneB3evD5SMX

这不是访问令牌通常的样子。它看起来更像是用逗号分隔的访问令牌和刷新令牌。
