javascript - AngularJS - 引用错误 : success is not defined

Question

当从 Controller 向我的 node.js 后端执行 Restful 调用时，我收到“ReferenceError: success is not defined”，如下所示:

authControllers.js:

authControllers.controller('authCtrl', ['$scope', '$location', '$window', 'UserService', 'AuthenticationService',
function authCtrl($scope, $location, $window, UserService, AuthenticationService) {
  $scope.me = function() {    
    UserService.me(function(res) {
      $scope.myDetails = res;
    }, function() {
      console.log('Failed to fetch details');
      $rootScope.error = 'Failed to fetch details';
    })
  };      
}]);

authServices.js:

authServices.factory('UserService',['$http', function($http) {
  return {        
    me:function() {
    return $http.get(options.api.base_url + '/me').success(success).error(error)
    }
  }
}]);

html:

<div class="row" data-ng-controller="authCtrl" data-ng-init="me()">
    <div class="col-lg-12">
        <div class="panel panel-primary">
            <div class="panel-heading">
                <strong>Your Details</strong>
            </div>
            <div class="panel-body">
                <p>{{myDetails.data.username}}</p>
                <p>{{myDetails.data.email}}</p>
            </div>
        </div>
    </div>
</div>

正在接收一个成功的 nodeJs 调用并且它也在返回数据，但是无法在前端获取它。请帮忙!

Answer 1

错误是:

return $http.get(options.api.base_url + '/me').success(success).error(error)

要修复它，请不要尝试引用不存在的 success 和 error 函数。

return $http.get(options.api.base_url + '/me')

当您正确使用 $http 时，Angular 会返回一个 $q promise。成功和错误解决方法已弃用。

The $http legacy promise methods success and error have been deprecated.
