/ event-id facebook返回空数据

Question

我可以抓住Facebook帐户的个人资料信息：

var facebookExample = angular.module('starter', ['ionic', 'ngStorage', 'ngCordova'])

facebookExample.controller("ProfileController", function($scope, $http, $localStorage, $location) {

$scope.init = function() {
    if($localStorage.hasOwnProperty("accessToken") === true) {
        $http.get("https://graph.facebook.com/v2.2/me", { params: { access_token: $localStorage.accessToken, fields: "id,name,gender,location,website,picture,relationship_status", format: "json" }}).then(function(result) {
            $scope.profileData = result.data;
        }, function(error) {
            alert("There was a problem getting your profile.  Check the logs for details.");
            console.log(error);
        });
    } else {
        alert("Not signed in");
        $location.path("/login");
    }
};

});

现在，我正试图通过以下方式获取Facebook事件的信息：

facebookExample.controller("EventController", function($scope, $http, $localStorage, $location) {

$scope.init = function() {
    if($localStorage.hasOwnProperty("accessToken") === true) {
        $http.get("https://graph.facebook.com/v2.2/{event-id}", { params: { access_token: $localStorage.accessToken, fields: "id, name, cover, place, description", format: "json" }}).then(function(result) {
            $scope.eventData = result.data;
        }, function(error) {
            alert("There was a problem getting your profile.  Check the logs for details.");
            console.log(error);
        });
    } else {
        alert("Not signed in");
        $location.path("/login");
    }
};

});

但我的eventData返回空...我正在构建一个带有cordova和angular的离子应用程序。有人可以帮忙吗？
