fail to retrieve request token for yahoo integration in android?

问题

I am trying to integrate yahoo in my app. I am trying,

private static final String YAHOO_CALLBACK_URI = "MyApp://oauth";
public static final String YAHOO_REQUEST_TOKEN_URL = "http://api.login.yahoo.com/oauth/request_token";//api.login.yahoo.com
public static final String YAHOO_ACCESS_TOKEN_URL = "http://api.login.yahoo.com/oauth/access_token";
public static final String YAHOO_AUTHORIZE_URL = "http://api.login.yahoo.com/authorize";


CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(YAHOO_CONSUMER_KEY, YAHOO_CONSUMER_SERECT_KEY);
    OAuthProvider provider = new CommonsHttpOAuthProvider(YAHOO_REQUEST_TOKEN_URL, YAHOO_ACCESS_TOKEN_URL, YAHOO_AUTHORIZE_URL);
    provider.setOAuth10a(true);
    try {
        String authUrl = provider.retrieveRequestToken(consumer, YAHOO_CALLBACK_URI);// Can I pass Null for callback url.
        System.out.println("AuthURL = " + authUrl);
    } catch (OAuthMessageSignerException e) {
        e.printStackTrace();
    } catch (OAuthNotAuthorizedException e) {
        e.printStackTrace();
    } catch (OAuthExpectationFailedException e) {
        e.printStackTrace();
    } catch (OAuthCommunicationException e) {
        e.printStackTrace();
    }

getting

oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: Service provider responded in error: 404 (Not Found)

Why we are unable to retrieve request token.

回答1:

Make sure your app on Yahoo is registered as Web-Based. When you register as a Web-Based application, give a valid Application URL and App Domain of your choice (both should be the same domain), but has not been used by anyone else. I, for example, have the url of a website I own. This will also be used as the callback url in your consumer.
Instead of calling "MyApp://oauth", give a valid http callback url (the same one you used to register the app). With that much, your code above should work.
Open a new Webview and call the authUrl. Once your app is authorised, intercept the call to your application url by overriding the "onPageStarted" method. There, make a callback to your app by launching a new intent pointing to "MyApp://oauth".

Please let me know if any of the obove steps confuse you - I am more than happy to help.

I had followed the above mentioned 3#poits and able to do the call back to the application. The whole problem started with YAHOO OAUTH Process. Now Yahoo doesnt take the Custom Call back urls, It has to be a valid http url. n There are couple of issues i have it which i am solving on my own,like Having a CUSTOMi Dialog box which can be used to call the Web-view YAHOO Auth URL similar to FB Dialog.

Thanks for the
