我試圖通過以下示例在我的Android應用中實現tumblr登錄：https://github.com/jansanz/TumblrOAuthDemo。Tumblr用Android登錄Android使用SignPost
我可以得到請求令牌。但是當我試圖檢索AccessToken時，它給了我一個例外。 下面是代碼：
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");
}
}
的provider.retrieveRequestToken()第一個電話就可以了。我可以檢索令牌和tokenSecret。但是當我嘗試通過調用provider.retrieveAccessToken(consumer,oauth_verifier);得到的accessToken我得到了OAuthCommunicationException的OAuthCommunicationException 堆棧跟蹤是：
