【问题描述】：

当我尝试查询 facebook 时，出现以下异常： "必须使用活动访问令牌来查询有关当前用户的信息。"

这是请求：

AccessToken accessToken = AccessToken.getCurrentAccessToken();
            GraphRequest request = GraphRequest.newMeRequest(
                    accessToken,
                    new GraphRequest.GraphJSONObjectCallback() 
                        @Override
                        public void onCompleted(JSONObject object, GraphResponse response) 
                            FacebookRequestError responseError = response.getError();
                            if(responseError != null)
                                if(responseError.getCategory().equals(FacebookRequestError.Category.LOGIN_RECOVERABLE))
                                    LoginManager.getInstance().resolveError(MainActivity.this, response);
                                 else 
                                    Toast.makeText(MainActivity.this, getString(R.string.facebookError), Toast.LENGTH_LONG).show();

                                    Log.e(TAG, Helper.isFacebookLogin() + "");
                                    return;
                                
                             else 
                                try 
                                    Log.e(TAG + " newMeRequest id", object.getString("id"));
                                 catch (JSONException e) 
                                    Log.e(TAG + " newMeRequest JSONerror", e.getMessage());
                                
                            


                        

                    );
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,gender");
            request.setParameters(parameters);
            reques

t.executeAsync();

Helper.isFacebookLogin() 是：

public static boolean isFacebookLogin()
    return accessToken != null && !accessToken.isExpired();

并返回true。

如果返回 true，为什么我会收到错误消息？

尝试使用以下代码，此代码已在多个边界条件下进行了广泛测试并多次使用：

//on click of fb button
        private void handleFBLogin() 
                AccessToken accessToken = AccessToken.getCurrentAccessToken();
                LoginManager.getInstance().logOut();
                boolean isLoggedIn = accessToken != null && !accessToken.isExpired();
                LoginManager.getInstance().logInWithReadPermissions(ActivityLogin.this, Arrays.asList("public_profile", "email"));
                LoginManager.getInstance().registerCallback(callbackManager,
                        new FacebookCallback<LoginResult>() 
                            @Override
                            public void onSuccess(final LoginResult loginResult) 
                                runOnUiThread(new Runnable() 
                                    @Override
                                    public void run() 
                                        setFacebookData(loginResult, d);

                            @Override
                            public void onCancel() 
    Toast.makeText(getApplicationContext(), "Canceled login ", Toast.LENGTH_SHORT); toast.show();

                                        LoginManager.getInstance().logOut();

            parameters.putString("fields", "id,email,first_name,last_name,gender");
            request.setParameters(parameters);
            request.executeAsync();
