用户已登录FB时的FaceBook Javascript SDK OAuth授权

我正在尝试找到用户从我的应用程序注销时的情况解决方案,但仍然在Facebook上登录,并尝试通过OAuth再次登录我的应用程序。
我正在通过收听'auth.login'事件检查授权状态 当用户在这种情况下单击facebook-connect按钮时,弹出窗口会自动关闭,然后没有任何反应(因为用户已登录facebook,登录事件未被触发)。如果我添加getLoginStatus()检查,那么用户在打开页面时会自动登录到我的应用程序,即使他没有点击facebook-connect按钮(这就是我不想要的)任何想法?谢谢!

当用户已登录此FB事件时,请在此处指定执行代码。

 FB.getLoginStatus(function(response) {
  if (response.status === 'connected') {
   // the user is logged in and has authenticated your
   // app, and response.authResponse supplies
   // the user's ID, a valid access token, a signed
   // request, and the time the access token 

   // and signed request each expire
    var uid = response.authResponse.userID;
    var accessToken = response.authResponse.accessToken;

 } else if (response.status === 'not_authorized') {
    // the user is logged in to Facebook, 
    // but has not authenticated your app
  } else {
    // the user isn't logged in to Facebook.
  }
});
