无法张贴在脸书墙上。 （＃200）用户尚未授权应用程序执行此操作android facebook SDK错误

Question

我知道这个问题之前已被多次询问过。但这些答案都不适合我。这似乎是许可的一些问题。它似乎没有存储发布权限，并且每次用户尝试发布内容时都会不断询问权限。这是我的代码。

public class MainActivity extends Activity {

    private Session.StatusCallback statusCallback = new SessionStatusCallback();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button btn = (Button) findViewById(R.id.btn_post);
        btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                postToFaceBook();
            }

        });

        Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
        //get the active Facebook session
        Session session = Session.getActiveSession();
        //If no active sessions found
        if (session == null) {
            if (savedInstanceState != null) {
                //Restore the saved session from bundle if any
                session = Session.restoreSession(this, null, statusCallback, savedInstanceState);
            }
            if (session == null) {
                //If the session has not been stored in bundle, create a new session
                session = new Session(this);
            }
            //set session as current active session
            Session.setActiveSession(session);
            //If the session has not been opened yet, log the user into facebook
            //It does not involve interaction of user with facebook
            if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
                session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
            }
        }

    }

    @Override
    protected void onStart() {
        super.onStart();
        Session.getActiveSession().addCallback(statusCallback);
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        Session session = Session.getActiveSession();
        Session.saveSession(session, outState);
    }


    @Override
    protected void onStop() {
        super.onStop();
        Session.getActiveSession().removeCallback(statusCallback);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);
        Session.getActiveSession().onActivityResult(this, requestCode, resultCode, intent);
    }

    private class SessionStatusCallback implements Session.StatusCallback {
        @Override
        public void call(Session session, SessionState state, Exception exception) {

            if (exception != null) {
                exception.printStackTrace();
            }
        }

    }

    private void postToFaceBook() {
        Log.i("fb", "inside share via facebook");
        Session session = Session.getActiveSession();
        if (!session.isOpened() && !session.isClosed()) {
            //Interact with the user to get user name and password for facebook
            session.openForRead(new Session.OpenRequest(MainActivity.this).setCallback(statusCallback));
        } else {
            Session.openActiveSession(MainActivity.this, true, statusCallback);
        }

        Bundle postParams = new Bundle();
        postParams.putString("message", "testing");
        postParams.putString("link", "https://www.youtube.com/watch?v=GcNNx2zdXN4");


        //get the current active facebook session
        session = Session.getActiveSession();
        //If the session is open
        if(session.isOpened()) {
            Log.i("fb", "inside isopened");
            //Get the list of permissions associated with the session
            List<String> permissions = session.getPermissions();
            //if the session does not have video_upload permission
            if(!permissions.contains("publish_actions") || !permissions.contains("publish_stream")) {
                Log.i("fb", "doesn't contain permission");
                //Get the permission from user to upload the video to facebook
                Session.NewPermissionsRequest newPermissionsRequest = new Session
                        .NewPermissionsRequest(MainActivity.this, Arrays.asList("publish_actions" , "publish_stream"));
                session.requestNewPublishPermissions(newPermissionsRequest);
            }

            Request.Callback callback= new Request.Callback() {
                public void onCompleted(Response response) {
                    Log.i("fb", "On completed");
                    FacebookRequestError error = response.getError();
                    if (error != null) {
                        //AppUtils.showToastMessage(th, error.getErrorMessage());
                        Toast.makeText(MainActivity.this, error.getErrorMessage(), Toast.LENGTH_SHORT).show();
                    } else {
                        //AppUtils.showToastMessage(mActivity, mResources.getString(R.string.posted_successfully));
                        //AppUtils.setSharedOrigami(mActivity, mPortraitKey);
                        Toast.makeText(MainActivity.this, "success", Toast.LENGTH_SHORT).show();
                    }

                    //mFacebookDialog.dismiss();
                }
            };

            Request request = new Request(session,

在使用publish_action权限之前，是否需要提交应用以供审核？任何帮助，将不胜感激。谢谢！

你所拥有的是一个常见问题。问题是您在调用requestNewPublishPermissions后立即向我发送请求/提要。

但是，requestNewPublishPermissions是一个异步请求，因此当您向我/ Feed发帖时，您实际上还没有发布权限。您需要保存您即将发布的事实，请求发布权限，然后当该请求返回时（在onActivityResult中或在回调中），请将帖子发送到＆＃34; me / feed＆＃34 ;然后

查看SDK附带的Hello Facebook示例应用程序，它会向您展示如何请求发布权限，并推迟发布，直到您拥有所有权限。
