SignPost在安卓系统中的Tumblr登录

Question

我正试图在我的安卓应用程序中实现一个tumblr登录，方法是遵循以下示例：https://github.com/jansanz/TumblrOAuthDemo。

我可以得到请求令牌。但是当我试图检索AccessToken时，它给了我一个例外。以下是代码：

public class TumblrDemoActivity extends Activity {

private static final String TAG = "TumblrDemo";

private static final String PREFS = "prefs_tumblr";
private static final String PREF_TOKEN = "pref_token_tumblr";
private static final String PREF_TOKEN_SECRET = "pref_token_secret_tumblr";

private static final String REQUEST_TOKEN_URL = "http://www.tumblr.com/oauth/request_token";
private static final String ACCESS_TOKEN_URL = "http://www.tumblr.com/oauth/access_token";
private static final String AUTH_URL = "http://www.tumblr.com/oauth/authorize";

// Taken from Tumblr app registration
private static final String CONSUMER_KEY = "consumer key from tumblr app";
private static final String CONSUMER_SECRET = "consumer secret from tumblr app";

private static final String CALLBACK_URL = "tumblrdemo://www.android-ios-tutorials.com";//"tumblrdemo://tumblrdemo.com/ok";

CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET); 
CommonsHttpOAuthProvider provider = new CommonsHttpOAuthProvider(
        REQUEST_TOKEN_URL,
        ACCESS_TOKEN_URL,
        AUTH_URL);

SharedPreferences prefs;

String token;
String tokenSecret;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    prefs = getSharedPreferences(PREFS, Context.MODE_PRIVATE);
    consumer.setMessageSigner(new HmacSha1MessageSigner());
    // It uses this signature by default
    // consumer.setMessageSigner(new HmacSha1MessageSigner());

    // To get the oauth token after the user has granted permissions
    Uri uri = this.getIntent().getData();
    if (uri != null) {

        Log.d(TAG, "accessToken       : "+consumer.getToken());
        Log.d(TAG, "accessTokenSecret : "+consumer.getTokenSecret());

        //retrieve token and tokenSecret saved in retrieveRequestToken() call
        this.token = prefs.getString(PREF_TOKEN, null);
        this.tokenSecret = prefs.getString(PREF_TOKEN_SECRET, null);
        Log.d(TAG, "this.token       : "+token);
        Log.d(TAG, "this.tokenSecret : "+tokenSecret);

        consumer.setTokenWithSecret(token, tokenSecret);

        Log.d(TAG, "consumer.token       : "+consumer.getToken());
        Log.d(TAG, "consumer.tokenSecret : "+consumer.getTokenSecret());

        String token = uri.getQueryParameter("oauth_token");
        String verifier = uri.getQueryParameter("oauth_verifier");

        Log.v(TAG, "Token:" +token);
        Log.v(TAG, "Verifier:" +verifier);

        try {
            provider.retrieveAccessToken(consumer, verifier);
            Log.d(TAG, "accessToken       retrieveAccessToken    : "+consumer.getToken());
            Log.d(TAG, "accessTokenSecret retrieveAccessToken    : "+consumer.getTokenSecret());

        } catch (OAuthMessageSignerException e) {
            e.printStackTrace();
        } catch (OAuthNotAuthorizedException e) {
            e.printStackTrace();
        } catch (OAuthExpectationFailedException e) {
            e.printStackTrace();
        } catch (OAuthCommunicationException e) {
            e.printStackTrace();
        }
    } else {
        String authUrl;
        try {
            authUrl = provider.retrieveRequestToken(consumer, CALLBACK_URL);
            Log.v(TAG, "Auth url:" + authUrl);
            Log.d(TAG, "accessToken       : "+consumer.getToken());
            Log.d(TAG, "accessTokenSecret : "+consumer.getTokenSecret());

            //save tokens in preferences
            SharedPreferences.Editor editor = prefs.edit();
            editor.putString(PREF_TOKEN, consumer.getToken());
            editor.putString(PREF_TOKEN_SECRET, consumer.getTokenSecret());
            editor.commit();

            startActivity(new Intent("android.intent.action.VIEW", Uri.parse(authUrl)));

        } catch (OAuthMessageSignerException e) {
            e.printStackTrace();
        } catch (OAuthNotAuthorizedException e) {
            e.printStackTrace();
        } catch (OAuthExpectationFailedException e) {
            e.printStackTrace();
        } catch (OAuthCommunicationException e) {
            e.printStackTrace();
        }
    }
}

@Override
protected void onResume() {
    super.onResume();
    Log.v(TAG, "onResume");
}

}

provider.retrieveRequestToken()的第一个调用是可以的。我可以检索令牌和tokenSecret。但是，当我试图通过调用accessToken获得provider.retrieveAccessToken(consumer,oauth_verifier);时，我得到了一个OAuthCommunicationException，OAuthCommunicationException的堆栈跟踪是：

任何帮助都会被接受。

Answer 1

我已经为Tumblr Login创建了一个小型库，使用oauth标志柱和大型for。你可以在这里找到它：

使用oauth标志柱的Tumblr登录API

我希望这个图书馆能对其他有同样问题的人有所帮助。

Answer 2

我知道这是一个相当古老的线索。但对于任何晚来的人来说..。我构建了一个库来实现登录过程的自动化。另外，这个链接被破坏了。可能想要更新一下。

它可以在Github上使用。
