通过Facebook App登录到我的Web应用程序时未显示“权限”对话框

Question

我已经在我的Web应用程序中实现了Facebook Login。它工作正常，但不显示登录时间“权限”对话框。

window.fbAsyncInit = function() {
            FB.init({
              appId      : '',
              oauth: true,
               autoLogAppEvents : true,
              xfbml            : true,
              version          : ''
            });
            FB.getLoginStatus(function(response) {
                if (response.status === 'connected') {
                    //console.log('connected');
                    //document.getElementById('status').innerHTML = 'We are connected.';
                     //document.getElementById('loginFbBtn').style.visibility = 'hidden';
                    //getInfo();
                } else if (response.status === 'not_authorized') {
                      // console.log('not_authorized');
                    //document.getElementById('status').innerHTML = 'We are not logged in.'
                } else {
                     //  console.log('not logged into Facebook');
                    //document.getElementById('status').innerHTML = 'You are not logged into Facebookfccvyh.';
                }
            });
        };

        (function(d, s, id){
            var js, fjs = d.getElementsByTagName(s)[0];
            if (d.getElementById(id)) {return;}
            js = d.createElement(s); js.id = id;
            js.src = "//connect.facebook.net/en_US/sdk.js";
            fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'facebook-jssdk'));

        function fbRegistration() {
             FB.getLoginStatus(function(response) {
                  //console.log(response);  
                  if (response && response.status === 'connected') {

                  }else{
                      FB.login(function(response) {
                            showLoader();
                        if (response.status === 'connected') {
                           FB.api('/me', 'GET', {fields: 'first_name,last_name,name,id,email,gender,birthday,picture.width(150).height(150)'}, function(response) {

                                if(response.gender === 'male'){

                                });

                            });
                        } else if (response.status === 'not_authorized') {
