angularjs – 使用Firebase注销

<button ng-click="logOut(user)">
        GOING OUT
      </button>

这是他们如何登录

$scope.signIn = function (user) {
    $scope.signInErrorShow = false;
    if (user && user.email && user.pwdForLogin) {
      auth.$authWithPassword({
        email: user.email,password: user.pwdForLogin
      }).then(function (authData) {
        console.log("Logged in as:" + authData.password.email);
        ref.child("users").child(authData.uid).once('value',function (snapshot) {
          var val = snapshot.val();
          $scope.$apply(function () {
            $rootScope.displayName = val;
          });
        });
        $scope.userLogin = true;
        $ionicLoading.hide();
        $scope.closeModal();
        $rootScope.$broadcast('');
      }).catch(function (error) {
        $ionicLoading.hide();
      });
    } else
    $scope.signInErrorShow = true;
  };

而我正在尝试调用logOut

$scope.logOut = function(user) {
    ref.unauth();
  };

一旦我呼叫退出,我没有看到任何帖子或进入浏览器的网络部分.

在Firebase文档中,他们所说的注销就是这个

Logging Users Out

Calling unauth() invalidates the user’s token and logs them out of your application:

Copy
ref.unauth();
If you had previously used the onAuth() method to listen for authentication state,your callback would now be invoked with null for authData.

那我该怎么办？
