Question

我已成功将FB与我的应用程序集成。我希望在从facebook帐户授予应用程序权限后自动将一些文本，链接，图像发布到我的Facebook墙上。我尝试使用以下提供的逻辑但是我正在

{Response: responseCode: 403,graphObject: null,error: {errorCode: 200,errorType: 
OAuthException,errorMessege: (#200) The user hasn't authorized the application
to perform this action}, isFromCache:false

    requestWindowFeature(Window.FEATURE_NO_TITLE);

    if (savedInstanceState == null) {
        // Add the fragment on initial activity setup
        mainFragment = new MainFragment();
        getSupportFragmentManager()
        .beginTransaction()
        .add(android.R.id.content, mainFragment)
        .commit();
    } else {
        // Or set the fragment from restored state info
        mainFragment = (MainFragment) getSupportFragmentManager()
        .findFragmentById(android.R.id.content);

Answer 1

错误消息表示您未使用publish_actions授权用户。在调试器中测试访问令牌以找出授权的权限：https://developers.facebook.com/tools/debug/

顺便说一句，在审核过程中，您不会获得read_stream批准：https://developers.facebook.com/docs/facebook-login/permissions/v2.3#reference-read_stream

...意思是，它仅适用于在App（Admin，Developer，Tester）中具有角色的用户。

经过大量研究后，我正确地修改了我的课程。在这里，我发布了修改后的代码，可以帮助其他人。

public class MainFragment extends Fragment {
private static final String TAG = "MainFragment";
private UiLifecycleHelper uiHelper; 

private Session.StatusCallback callback=new Session.StatusCallback(){
    @Override
    public void call(Session session, SessionState state, Exception exception) {
        onSessionStateChange(session, state, exception);
    }

};  

private void onSessionStateChange(Session session, SessionState state, Exception exception) {
    if (state.isOpened()) {
        Log.i(TAG, "Logged in...");
        publishStory(session);
    } else if (state.isClosed()) {
        Log.i(TAG, "Logged out...");
    }
}


public void publishStory(Session currentSession) {
     Bundle params = new Bundle();
     params.putString("message", "Hey I am using this app");
        params.putString("name", "Dexter");
        params.putString("caption", "londatiga.net");
        params.putString("link", "http://www.londatiga.net");

        params.putString("picture", "http://twitpic.com/show/thumb/6hqd44");                                                

     WebDialog feedDialog = (new WebDialog.FeedDialogBuilder(getActivity(),currentSession, params))
       .setOnCompleteListener(new OnCompleteListener() {

       @Override

        if (error == null) {
         // When the story is posted, echo the success
         // and the post Id.
         final String postId = values.getString("post_id");
         if (postId != null) {
             Intent i=new Intent(getActivity(),MainActivity.class);//FacebookActivity.class);
             startActivity(i);
             getActivity().finish();                               // do some stuff
         } else {

       }

      }).setFrom("").build();
