Facebook登录不返回用户access_token

这是我的第一篇文章,如果我不遵守社区规则,请告诉我。

现在来问题了!我一直在尝试为应用程序设置Facebook登录过程,我已经获得了添加GUI元素(内置的Facebook登录按钮),并且按下按钮并要求用户/通行证,授予应用访问用户帐户的权限。我面临的问题是,当使用以下代码从应用程序获取回调值时,我什么也得不到(没有打印值)。现在我打印到LogCat任意值,但是一旦打印工作,我会查看用户access_token和其他信息(最初没有工作)。任何帮助表示赞赏!

protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_connect_accounts);

            Log.i("fromMe", "test1");
            FacebookSdk.sdkInitialize(this.getApplicationContext());
            callbackManager = CallbackManager.Factory.create();
            LoginButton loginButton = (LoginButton)findViewById(R.id.login_button);
            loginButton.registerCallback(callbackManager, new   FacebookCallback<LoginResult>(){

                public void onSuccess(LoginResult loginResult) {
                    Log.i("fromMe", "1");
                }

                public void onCancel() {
                    Log.i("fromMe", "2");
                }

                public void onError(FacebookException exception) {
                    Log.i("fromMe", "3");
                }
            });
        }

我从未使用内置的facebook按钮,而是使用普通按钮并单击一个监听器。我在onClick()

中调用此方法
 myButton.setOnClickListener(new View.OnClickListener(){
    @Override
    public void onClick(View v){
        //Starting facebook signIN
        startFbSignIn();
    }
});

<强> startFbSignIn();

private void startFbSignIn() {

        List<String> permissions = new ArrayList<>();
        permissions.add("email");

        Session.openActiveSession(this, true, permissions, new Session.StatusCallback() {
            @Override
            public void call(final Session session, SessionState sessionState, Exception e) {

                Log.d("X", "Call Called");

                if (session.isOpened()) {

                    Log.d("X", "SessionOpened" + session.getAccessToken());

                    //Showing some loading


                    Request.newMeRequest(session, new Request.GraphUserCallback() {
                        @Override
                        public void onCompleted(GraphUser graphUser, Response response) {

                            //FACEBOOOK SIGNIN SUCCESS
                            Log.i("X", "Facebook Login Success");
                            //Log
                            Log.d("X", "GRAPH USER:" + graphUser.toString());


                            String name = graphUser.getName();
                            //.....

                        }
                    }).executeAsync();

                } else {
                    Log.d("X", "SessioNOTopened");
                }

            }
        });

    }

上述方法成功地为我工作,您的onActivityResult()必须看起来像这样

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    //Facebook Session Manager
    Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

如果Log.i("fromMe", "1");有效,您可以致电:

AccessToken accessToken = loginResult.getAccessToken(); 

onSuccess()

并在onActivityResult(int requestCode, int resultCode, Intent data) 添加:

super.onActivityResult(requestCode, resultCode, data); 
callbackManager.onActivityResult(requestCode, resultCode, data);

可能导致facebook SDK中的错误无法直接获取accessToken。我们需要创建一个accessToken跟踪器,然后获取accessToken

    private AccessTokenTracker accessTokenTracker; 
    accessTokenTracker = new AccessTokenTracker() {


        @Override
        protected void onCurrentAccessTokenChanged(AccessToken oldAccessToken, AccessToken newAccessToken) {
            try {

                if (newAccessToken.getToken() != null) {
                    facebookAccessToken = newAccessToken.getToken();
                    //this is your accessToken here

                }
                else if (oldAccessToken.getToken() != null) {
                    facebookAccessToken = oldAccessToken.getToken();
                     //this is your accessToken here
                }else {
                    Toast.makeText(getBaseContext(), "Facebook Login Failed", Toast.LENGTH_LONG).show();
                }

                if(oldAccessToken.getToken()!=null)
                Log.e("old", oldAccessToken.getToken());
            }catch (Exception e){
                e.printStackTrace();
            }

        }
    };

成功完成后,在活动的onStop方法旁边,并确保在那里停止跟踪accessToken。

    accessTokenTracker.stopTracking();
