AngularJS - ReferenceError:未定义成功

Question

当从控制器到我的node.js后端执行Restful调用时,我得到"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,它也返回数据,但无法在前端获取它.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success和error不存在的函数.

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

$q当你调用时$http,Angular会返回一个你正确使用的承诺.不推荐使用成功和错误解决方法.

$ http遗留承诺方法成功和错误已被弃用.
