適用於Android的Twitter的oAuth錯誤

Question

我正在使用一個應用程序通過Twitter4j庫在Twitter中授權用戶。 我想合並一個功能，我的移動應用程序打開。 它具有一個登錄按鈕，單擊它會顯示Twitter登錄對話框，並允許您輸入登錄信息。 登錄完成后，將打開另一個屏幕。

import android.widget.Toast;

public class AndTweetVJActivity extends Activity {
    /** Called when the activity is first created. */


    Twitter twitter;
    RequestToken requestToken;
    public final static String consumerKey = "myKey"; // "your key here";
    public final static String consumerSecret = "myKey"; // "your secret key here";
    private final String CALLBACKURL = "T4JOAuth://main";  //Callback URL that tells the WebView to load this activity when it finishes with twitter.com. (see manifest)


        //Calls the OAuth login method as soon as its started
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            OAuthLogin();
        }

        /* Creates object of Twitter and sets consumerKey and consumerSecret
         * - Prepares the URL accordingly and opens the WebView for the user to provide sign-in details
         * - When user finishes signing-in, WebView opens your activity back  */

        void OAuthLogin() {
            try {
                twitter = new TwitterFactory().getInstance();
                twitter.setOAuthConsumer(consumerKey, consumerSecret);
                requestToken = twitter.getOAuthRequestToken(CALLBACKURL);
                String authUrl = requestToken.getAuthenticationURL();
                this.startActivity(new Intent(Intent.ACTION_VIEW, Uri
                        .parse(authUrl)));
            } catch (TwitterException ex) {
                Toast.makeText(this, ex.getMessage(), Toast.LENGTH_LONG).show();
                Log.e("in Main.OAuthLogin", ex.getMessage());
            }
        }


        /*
         * - Called when WebView calls your activity back.(This happens when the user has finished signing in)
         * - Extracts the verifier from the URI received
         * - Extracts the token and secret from the URL 
         */
        @Override
        protected void onNewIntent(Intent intent) {
            super.onNewIntent(intent);
            Uri uri = intent.getData();
            try {
                String verifier = uri.getQueryParameter("oauth_verifier");
                AccessToken accessToken = twitter.getOAuthAccessToken(requestToken,verifier);
                String token = accessToken.getToken(), secret = accessToken.getTokenSecret();
                //displayTimeLine(token, secret); //after everything, display the first tweet 

            } catch (TwitterException ex) {
                Log.e("Main.onNewIntent", "" + ex.getMessage());
            }

        }
    }

但是在運行此應用程序時，它在logcat中給我錯誤：

11-18 10:36:27.727: E/in Main.OAuthLogin(282): 401:Authentication credentials (https://dev.twitter.com/docs/auth) were missing or incorrect. Ensure that you have set valid conumer key/secret, access token/secret, and the system clock in in sync.

11-18 10:36:27.727: E/in Main.OAuthLogin(282): </hash>

我相信我沒有設置回調URL，但是我在我的應用程序中也對https://dev.twitter.com/pages/welcome-anywhere進行了設置。

Answer 1

確保尚未在Twitter應用程序注冊時在“桌面應用程序”類別中注冊您的應用程序。

Answer 2

糟糕...我的Web服務器已關閉，直到5分鍾前我才注意到它。 感謝所有建議。 我已經做了這些事情。
