如何使用 Twitter4J api 对 Twitter 进行 oauth

Question

我想使用 Twitter4j api 验证 twitter，但它给出了以下错误：

   09-13 12:12:09.223: WARN/System.err(677): oauth.signpost.exception.OAuthNotAuthorizedException: Authorization failed (server replied with a 401). This can happen if the consumer key was not correct or the signatures did not match.

我使用下面的代码；

public class OAuthTwitter extends Activity {
public final static String CALLBACK_URL = "callback://twitter"; // ----
                                                                // (4)

private CommonsHttpOAuthConsumer commonHttpOAuthConsumer;
private OAuthProvider authProvider;

private Twitter twitter;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    commonHttpOAuthConsumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY,
            CONSUMER_SECRET); // ----- (5)
    authProvider = new DefaultOAuthProvider(
            "https://api.twitter.com/oauth/request_token",
            "https://api.twitter.com/oauth/access_token",
            "https://api.twitter.com/oauth/authorize");
    try {
        String oAuthURL = authProvider.retrieveRequestToken(
                commonHttpOAuthConsumer, CALLBACK_URL);

        this.startActivity(new Intent(Intent.ACTION_VIEW, Uri
                .parse(oAuthURL)));

    } catch (OAuthMessageSignerException e) {
        Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
        e.printStackTrace();
    } catch (OAuthNotAuthorizedException e) {
        Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
        e.printStackTrace();
    } catch (OAuthExpectationFailedException e) {
        Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
        e.printStackTrace();
    } catch (OAuthCommunicationException e) {
        Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
        e.printStackTrace();
    }
}

protected void onNewIntent(Intent intent) { // ---- (6)
    super.onNewIntent(intent);

    Uri uri = intent.getData(); // ---- (7)
    if (uri != null && uri.toString().startsWith(CALLBACK_URL)) {
        String verifier = uri
                .getQueryParameter(oauth.signpost.OAuth.OAUTH_VERIFIER);
        try {
            authProvider.retrieveAccessToken(commonHttpOAuthConsumer,
                    verifier); // ---- (8)

            AccessToken accessToken = new AccessToken(
                    commonHttpOAuthConsumer.getToken(),
                    commonHttpOAuthConsumer.getTokenSecret()); // ---- (9)

            twitter = new TwitterFactory().getInstance(); // ---- (10)
            twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);

            twitter.setOAuthAccessToken(accessToken); // ---- (11)

            // Tweet message to be updated.
            String tweet = "Hiee there, This is send from my application - OAuth, Twitter";
            twitter.updateStatus(tweet); // ---- (12)
        } catch (Exception e) {
            Toast.makeText(getBaseContext(), e.getMessage(),
                    Toast.LENGTH_LONG);
        }
    }
}
}

使用罐子：signpost-commonshttp4-1.2.1.1.jar,signpost-core-1.2.jar,twitter4j-core-android-2.2.4.jar 请任何人告诉我我错在哪里。

错误是消费者密钥...意味着它可能是错误的..或者您已经正确创建了它 为此你必须 单击 dev.twitter.com 上的创建应用程序链接 然后使用您的推特帐户登录后，您必须在下一页上提供姓名等详细信息 你得到了secrate key和consumer key，callback url等...... 将该密钥放入您的代码中
