安卓推特回调问题

问题描述 投票:0回答:3

我在我的应用程序中实现了 Twitter,我在回调中遇到问题。

Twitter API 最近更新了,所以我无法发送回调 URL。

现在设置页面也发生了变化,没有用于选择基于 Web 的应用程序或桌面应用程序的选项。

如果我在此行中发送回调:

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.

但是如果我发送为 Null 重定向到 Twitter 登录页面,但在成功授权后它不会返回到我的应用程序。

显示密码后,我想重定向回我的应用程序。

注意:Twitter 已更新其 API,因此帖子中可用的旧代码无法使用。

我尝试了所有以下链接

链接 1, 链接 2, 链接 3, 链接4 , 链接5 , 链接 6

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

问题是回调 URl。 我们应该在应用程序设置页面的回调 URL 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调 URL,成功登录后将有一个名为Redirecting to your Application

的选项

你找到问题出在哪里了吗?我有同样的例外,最后我找到了它的来源。就是Twitter的设置页面发生了变化,您不能再选择基于Web的应用程序或桌面应用程序。但这里有一些提示:在您的 Twitter 应用程序的设置中,只需使用像 http://www.dummy.com 这样的虚拟网址填充回调 URL。这将隐式设置您的应用程序具有网络浏览器,然后当您发送自己的回调时,它将替换虚拟浏览器。 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
添加到应用程序中将解决问题。它将用户重定向到
Application
启动它以验证用户的
Twitter
帐户_

更新在

Manifest
_

<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>

在你的

TwitterManager
里,你拥有所有的
TwitterFactory
和所需的东西_

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";

终于可以得到你想要的一切了_ 例如,

getHost
getScheme
getEncodedQuery
getQuery
getEncodedSchemeSpecificPart
和更多根据您的需要使用通过回调返回的
intent
_

@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();
    }

希望对大家有所帮助_
