Angularjs工厂：在传球$范围，$路径，$ HTTP错误？ [英] Angularjs factory: errors on passing $scope,$route,$http?

问题描述

为什么下面我厂不断抛出一个错误，当 $范围，$路径，$ HTTP 是present？

  app.factory（factoryContacts功能（$范围，$路径，$ HTTP）{        返回{
            getContacts：功能（）{
               返回$ HTTP（{
                    方法：GET，
                    网址：PHP / listContacts.php
                }）。然后（功能（响应）{
                    $ scope.contacts = response.data;                 }）;
            }
        };
   }）;
 

我不能通 $范围，$路径，$ HTTP 进入工厂？

我这个基本一测试，它给了我同样的错误，

  app.provider（'的helloWorld'，函数（$范围内）{//注$范围为present
        //在提供的功能，你不能注入任何
        //服务或工厂。这只能在完成
        //$ get方法。        this.name =默认;        这一点。$ GET =功能（）{
            变量名称= this.name;
            返回{
                sayHello的：功能（）{
                    返回你好，+名字+！从供应商！
                }
            }
        };        this.setName =功能（名称）{
            this.name =名称;
        };
    }）;
 

我应该怎么办？

错误，

 错误：[$喷油器：unpr] http://errors.angularjs.org/1.2.6/$injector/unpr?p0=%24scopeProvider%20%3C-%20%24scope%20%3C-%20factoryContacts ...＆LT; NG-view类=NG-范围＆GT;
 

解决方案

  

我不能通$范围，$路径，$ HTTP到工厂？

为什么不$范围

您不能注入$范围到服务/工厂，其单并拥有的本地范围的。但是你可以使用 $ rootScope

要通过 $路线和 $ HTTP 使用注射这样写：

  app.factory（factoryContacts，['$路线'，'$ HTTP'，函数（$路径，$ HTTP）{        返回{
            getContacts：功能（）{
               返回$ HTTP（{
                    方法：GET，
                    网址：PHP / listContacts.php
                }）。然后（功能（响应）{
                    // ....                 }）;
            }
        };
   }]）;
 

Why my factory below keep throwing an error when the $scope, $route, $http are present?

app.factory("factoryContacts",function($scope,$route,$http){

        return {
            getContacts: function(){
               return $http({
                    method: 'GET', 
                    url:'php/listContacts.php'
                }).then(function(response) {
                    $scope.contacts = response.data;

                 });
            }
        };
   });

can't I pass $scope, $route, $http into a factory?

I tested with this basic one and it gives me the same error,

app.provider('helloWorld', function($scope) { // note $scope is present
        // In the provider function, you cannot inject any
        // service or factory. This can only be done at the
        // "$get" method.

        this.name = 'Default';

        this.$get = function() {
            var name = this.name;
            return {
                sayHello: function() {
                    return "Hello, " + name + "! From Provider!!"
                }
            }
        };

        this.setName = function(name) {
            this.name = name;
        };
    });

What should I do?

the error,

Error: [$injector:unpr] http://errors.angularjs.org/1.2.6/$injector/unpr?p0=%24scopeProvider%20%3C-%20%24scope%20%3C-%20factoryContacts ... <ng-view class="ng-scope">

解决方案

can't I pass $scope, $route, $http into a factory?

why not $scope

You can't inject $scope into service/factory, its singleton and has local scope. But you can use $rootScope

To pass $route and $http use injection and write like:

app.factory("factoryContacts",['$route','$http', function($route,$http){

        return {
            getContacts: function(){
               return $http({
                    method: 'GET', 
                    url:'php/listContacts.php'
                }).then(function(response) {
                    //....

                 });
            }
        };
   }]);
