javascript - 工厂方法 HTTP 不工作

Question

我无法从我的工厂 jsonLanguage 获取此 json 调用。

我的代码:

var App = angular.module('App', []);
var theLanguage = 'english';
App.factory('jsonLanguage', function($http){
    var theLanguage = 'english';
    return {

        get: function(theLanguage){
            var url = theLanguage + '.json';
            $http.get(url);
        }
    }

});
App.controller('mainController', function($scope, $http, $log, jsonLanguage) {

  //$http.get(theLanguage + '.json')

       jsonLanguage.success(function(res){  //here is the problem I tried .then and tried res.data no luck :(
          $scope.language = res;
$log.debug($scope.language);


        });
$log.debug($scope.language);
angular.forEach($scope.letter, function(single) {
        $log.log("hello worldsss");
 $log.log(single);
    });
});

App.controller('intervalController', function($scope, $log) {
    this.$log = $log;
    //var name = $scope.single;
    angular.forEach($scope.letter, function(single) {
        $log.log("hello worldsss");
 $log.log(single);
    });
    //$log.log(name);
  $log.log('Hello World!');

});

App.controller('clickController', function($scope) {

});

我尝试了 jsonLanguage，然后尝试了 res.data，但没有成功。

在这里你错过了几件事:

1. 返回$http服务 promise get method

   get: function(theLanguage){
       return $http.get(url);
   }
   

2. 调用工厂get method & 通过将 .then 放入其 promise 成功中获取数据通过该方法调用。

   jsonLanguage.get($scope.language).then(function(res){ 
      $scope.language = res.data;
   });
