Ionic Firebase。現在のユーザーを取得

Question

私は現在のユーザーを取得し、ページに表示したいと思う。私はFirebaseの文書に従って{{}}を使用していますが、動作しません。別のコードを見逃したり、別の方法を使用する必要がありますか？誰かが例を挙げることができます。

.controller('dashCtrl', function($scope, $state, $ionicPopup, $ionicLoading, $firebaseAuth) { //library injection 

var user = firebase.auth().currentUser; // code from firebase docs 
var name, email, photoUrl, uid; //declare the variable 

//checking the user 
if (user != null) { 
    name = user.displayName; //fetch the name 
    email = user.email; // fetch the email 
    photoUrl = user.photoURL; // fetch 
    uid = user.uid; // fetch uid 
    //password = user.password; 
    // The user's ID, unique to the Firebase project. Do NOT use 
    // this value to authenticate with your backend server, if 
    // you have one. Use User.getToken() instead. 

    console.log(email); //log the email. success display at console 
    console.log(uid); 
} 
    //logout function 
    $scope.logout=function(){ 
    firebase.auth().signOut().then(function() { 
    console.log("Sign-out successful."); 

    $state.go('login'); 
    }, function(error) { 
     // An error happened. 
    }); 
} 

})
