Android中Twitter的回调问题

标签: android twitter twitter-oauth

我已经在我的应用程序中实现了Twitter,我在Callback中面临问题。

Twitter API已于近期更新,因此我无法发送回拨网址。

此外,设置页面现在更改,没有选择基于Web的应用程序或桌面应用程序的选项。

如果我在此行发送回叫:

authUrl = provider.retrieveRequestToken(consumer,CALLBACK_URL);

它总是返回

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.

但如果我在重定向到Twitter登录页面中发送 Null ,但在成功授权后,它不会返回我的应用程序。

显示Pin编号后,我想重定向回我的应用程序。

注意:Twitter已经更新了他们的API,因此Post中提供的旧代码无效。

我尝试了所有以下链接

我的代码如下:

public class Main extends Activity {
OAuthConsumer consumer;
OAuthProvider provider;
Twitter twitter;
private static  String CALLBACK_URL = "twitterapptest://connect";


@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);

    consumer = new DefaultOAuthConsumer(
            "XXXXXXXXXXX",
            "XXXXXXXXXXXXX");

    provider = new DefaultOAuthProvider(
            "https://api.twitter.com/oauth/request_token",
            "https://api.twitter.com/oauth/access_token",
            "https://api.twitter.com/oauth/authorize");

    String authUrl = null;
    try {
        authUrl = provider.retrieveRequestToken(consumer,null);
         this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
    } catch (OAuthMessageSignerException e) {
        // TODO Auto-generated catch block

问题在于Callback URl。 我们应该在应用程序的设置页面中的CallBack URL的字段名称中提供一个虚拟回调URL。

如果我们这样做并在我们的代码中发送回拨网址,则在成功登录后会有一个名为重定向到您的应用的选项

您是否找到了问题的来源?我有同样的一个例外,最后我发现了它的来源。 Twitter的设置页面已经改变,你不能再选择基于Web的应用程序或桌面应用程序了。但是这里有一些提示:在你的Twitter应用程序的设置中,只需用http://www.dummy.com这样的虚拟URL填充回调URL。这将隐式设置您的应用程序具有Web浏览器,然后当您发送自己的回调时,它将重新设置虚拟的回调。 我花了很多时间才找到这个,所以我希望这个答案能帮助别人。

将以下Callback URL添加到应用中可以解决问题。它会将用户重定向到Application,启动它以验证用户的Twitter帐户_

Manifest _

中更新
<activity android:name="<YOUR ACTIVITY NAME>"
        android:launchMode="singleTask" android:theme="@android:style/Theme.Translucent.NoTitleBar"
        android:screenOrientation="portrait">
        <intent-filter>
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="x-oauthflow-twitter" android:host="callback" />
        </intent-filter>

TwitterManager中,您拥有所有TwitterFactory和所需内容_

final public static String  CALLBACK_SCHEME = "x-oauthflow-twitter";    
final public static String  CALLBACK_URL = CALLBACK_SCHEME + "://callback";
public static final String TWITTER_IEXTRA_OAUTH_VERIFIER = "oauth_verifier";

最后,您可以获得所需的一切_ 例如,getHostgetSchemegetEncodedQuerygetQuerygetEncodedSchemeSpecificPart等等根据您的需要使用 intent 通过回拨_返回

@Override
protected void onNewIntent(final Intent intent) {
    super.onNewIntent(intent);

    new AsyncTask<Void,Void,Void>(){
        @Override
        protected Void doInBackground(Void... arg0) {
            Uri uri = intent.getData();
            if (uri != null && uri.toString().startsWith(TwitterManager.TWITTER_CALLBACK_URL)) {
                String verifier = uri.getQueryParameter(TwitterManager.TWITTER_IEXTRA_OAUTH_VERIFIER);
                Log.e("---ActivityMain-onNewIntent---", "verifier:"+verifier+", uri- getQuery:"+uri.getQuery());
                Log.i(ApplicationPockets.TAG, "verifier : "+verifier);
                if(verifier != null){
                    try {
                     /*
                      *---Get the AccessToken and do what you like ... :)
                      */
                        AccessToken accessToken = twitter.getOAuthAccessToken(requestToken, verifier);
                       SharedPreferences.Editor e = context.getSharedPreferences(SF_TWITTER, Context.MODE_PRIVATE).edit();
                       e.putString(TWITTER_PREF_KEY_TOKEN, accessToken.getToken());
                       e.putString(TWITTER_PREF_KEY_SECRET, accessToken.getTokenSecret());
                      e.commit();
                     //Extra you would like to do...
                    } catch (TwitterException e) {
                        e.printStackTrace();
                    }
                }else{
                    //Logout Twitter.
                }
            }
            return null;
        }
    }.execute();
}

您的RequestToken _

  try {
         RequestToken requestToken = twitter.getOAuthRequestToken(TWITTER_CALLBACK_URL);
        //Toast.makeText(activity, "Please authorize this app!", Toast.LENGTH_LONG).show();
        activity.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(requestToken.getAuthenticationURL())));
      } catch (TwitterException e) {

          e.printStackTrace();
    }

我希望这对每个人都有帮助_
