工厂方法HTTP不起作用 [英] Factory method HTTP not working

问题描述

我无法从我的工厂 jsonLanguage 获得此json调用.

I cannot get this json call from my factory jsonLanguage.

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 ，然后又尝试了 res.data ，但是没有运气.

I tried jsonLanguage, and then and tried res.data with no luck.

推荐答案

在这里您错过了几件事:

Here you missed couple of things:

1. 从服务 get方法

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

调用工厂 get方法&通过将 .then 置于该方法调用之上，可以在其成功承诺范围内获取数据.

Call factory get method & get data inside its promise success by putting .then over that method call.

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