如何获取当前登录用户authservice的用户名

我想获取当前登录的用户名，以便我可以显示它。但是我不知道该怎么做？有任何想法吗 ？我正在使用authservice这是我想在其中获取用户名的我的角度控制器。

myApp.controller('meetupsController', ['$scope', '$resource', function ($scope, $resource) {
  var Meetup = $resource('/api/meetups');
$scope.meetups = []

  Meetup.query(function (results) {
    $scope.meetups = results;
  });


  $scope.createMeetup = function () {
    var meetup = new Meetup();
    meetup.name = $scope.meetupName;
    meetup.$save(function (result) {
      $scope.meetups.push(result);
      $scope.meetupName = '';
    });
  }
}]);

我的主要角度控制器代码var myApp = angular.module（'myApp'，['ngResource'，'ngRoute']）;

myApp.config(function ($routeProvider) {
  $routeProvider
    .when('/', {
      templateUrl: 'partials/main.html',
      access: {restricted: true}
    })
    .when('/api/meetups', {
      templateUrl: 'partials/main.html',
      access: {restricted: true}
    })
    .when('/login', {
      templateUrl: 'partials/login.html',
      controller: 'loginController',
      access: {restricted: false}
    })
    .when('/prive', {
      templateUrl: 'partials/prive.html',
      controller: 'userController',
      access: {restricted: true}
    })
    .when('/logout', {
      controller: 'logoutController',
      access: {restricted: true}
    })
    .when('/register', {
      templateUrl: 'partials/register.html',
      controller: 'registerController',
      access: {restricted: false}
    })
    .when('/one', {
      template: '<h1>This is page one!</h1>',
      access: {restricted: true}
    })
    .when('/two', {
      template: '<h1>This is page two!</h1>',
      access: {restricted: false}
    })
    .otherwise({
      redirectTo: '/'
    });
});

myApp.run(function ($rootScope, $location, $route, AuthService) {
  $rootScope.$on('$routeChangeStart',
    function (event, next, current) {
      AuthService.getUserStatus()
      .then(function(){
        if (next.access.restricted && !AuthService.isLoggedIn()){
          $location.path('/login');
          $route.reload();
        }
      });
  });
});







myApp.controller('meetupsController', ['$scope', '$resource', function ($scope, $resource) {
  var Meetup = $resource('/api/meetups');
$scope.meetups = []

  Meetup.query(function (results) {
    $scope.meetups = results;
  });


  $scope.createMeetup = function () {
    var meetup = new Meetup();
    meetup.name = $scope.meetupName;
    meetup.$save(function (result) {
      $scope.meetups.push(result);
      $scope.meetupName = '';
    });
  }





}]);

我的第二个角度代码：

var app = angular.module('myApp');

app.controller('loginController',
  ['$scope', '$location', 'AuthService',
  function ($scope, $location, AuthService) {

    $scope.login = function () {

      // initial values
      $scope.error = false;
      $scope.disabled = true;

      // call login from service
      AuthService.login($scope.loginForm.username, $scope.loginForm.password)
        // handle success
        .then(function () {
          $location.path('/');
          $scope.disabled = false;
          $scope.loginForm = {};
        })
        // handle error
        .catch(function () {
          $scope.error = true;
          $scope.errorMessage = "Invalid username and/or password";
          $scope.disabled = false;
          $scope.loginForm = {};
        });

    };

  $scope.posts = [];
  $scope.newPost = {created_by: '', text: '', created_at: ''};

  $scope.post = function(){
    $scope.newPost.created_at = Date.now();
    $scope.posts.push($scope.newPost);
    $scope.newPost = {created_by: '', text: '', created_at: ''};
  };
}]);

app.controller('logoutController',
  ['$scope', '$location', 'AuthService',
  function ($scope, $location, AuthService) {

    $scope.logout = function () {

      // call logout from service
      AuthService.logout()
        .then(function () {
          $location.path('/login');
        });

    };

    $scope.gotoregister = function () {




          $location.path('/register');


    };
    $scope.gotoprive = function () {




          $location.path('/prive');


    };

}]);

app.controller('registerController',
  ['$scope', '$location', 'AuthService',
  function ($scope, $location, AuthService) {

    $scope.register = function () {

      // initial values
      $scope.error = false;
      $scope.disabled = true;

      // call register from service
      AuthService.register($scope.registerForm.username, $scope.registerForm.password)
        // handle success
        .then(function () {
          $location.path('/login');
          $scope.disabled = false;
          $scope.registerForm = {};
        })
        // handle error
        .catch(function () {
          $scope.error = true;
          $scope.errorMessage = "Something went wrong!";
          $scope.disabled = false;
          $scope.registerForm = {};
        });

    };

}]);

和我的服务

angular.module('myApp').factory('AuthService',
  ['$q', '$timeout', '$http',
  function ($q, $timeout, $http) {

    // create user variable
    var user = null;

    // return available functions for use in the controllers
    return ({
      isLoggedIn: isLoggedIn,
      getUserStatus: getUserStatus,
      login: login,
      logout: logout,
      register: register
    });

    function isLoggedIn() {
      if(user) {
        return true;
      } else {
        return false;
      }
    }

    function getUserStatus() {
      return $http.get('/user/status')
      // handle success
      .success(function (data) {
        if(data.status){
          user = true;
        } else {
          user = false;
        }
      })
      // handle error
      .error(function (data) {
        user = false;
      });
    }

    function login(username, password) {

      // create a new instance of deferred
      var deferred = $q.defer();

      // send a post request to the server
      $http.post('/user/login',
        {username: username, password: password})
        // handle success
        .success(function (data, status) {
          if(status === 200 && data.status){
            user = true;
            deferred.resolve();
          } else {
            user = false;
            deferred.reject();
          }
        })
        // handle error
        .error(function (data) {
          user = false;
          deferred.reject();
        });

      // return promise object
      return deferred.promise;

    }

    function logout() {

      // create a new instance of deferred
      var deferred = $q.defer();

      // send a get request to the server
      $http.get('/user/logout')
        // handle success
        .success(function (data) {
          user = false;
          deferred.resolve();
        })
        // handle error
        .error(function (data) {
          user = false;
          deferred.reject();
        });

      // return promise object
      return deferred.promise;

    }

    function register(username, password) {

      // create a new instance of deferred
      var deferred = $q.defer();

      // send a post request to the server
      $http.post('/user/register',
        {username: username, password: password})
        // handle success
        .success(function (data, status) {
          if(status === 200 && data.status){
            deferred.resolve();
          } else {
            deferred.reject();
          }
        })
        // handle error
        .error(function (data) {
          deferred.reject();
        });

      // return promise object
      return deferred.promise;

    }

}]);
