服务注入与AngularJS控制器 [英] Service injection into controller with AngularJS

问题描述

我已经写在AngularJS一个服务，但我不能让它与做事情的角度种子的方式工作。

I have written a service in AngularJS, but I can't get it to work with the angular-seed way of doing things.

控制器code是如下：

The controller code is as follows:

/*function PhotoCtrl($scope, Photo) {
    $scope.photos = Photo.query();
}*/

angular.module('myApp.controllers', []).
    controller('PhotoCtrl', [function($scope,Photo) {
    $scope.photos = Photo.query();
}])
.controller('MyCtrl2', [function() {

}]);

请注意，该注释部分工作正常，但我想有些处理它像（推荐），第二种方式。

Note that the commented out section works fine, but I would like to handle it somewhat like the (recommended) second way.

我得到的错误是，照片是不确定的，所以我的猜测是我传递（注入）这是错误的方法，但我不能找出如何做是正确的。

The error I get is that Photo is undefined, so my guess would be my method of passing (injecting) it is wrong, but I can't find out how to do it correctly

推荐答案

您需要定义照片服务：

angular.module('myApp.controllers', [])
    .service('Photo', ['$log', function ($log) {

        return {
            query: function() {
                // the query code here.
            }
        };

    }])
    .controller('PhotoCtrl', ['$scope', 'Photo', function ($scope, Photo) {
        $scope.photos = Photo.query();
    }])
    .controller('MyCtrl2', [function() {

    }]);

一对夫妇引用：

• http://docs.angularjs.org/api/angular.Module


• http://docs.angularjs.org/api/AUTO.$provide#service

在上面的示例code我使用的参数走样，这是我为了避免问题与缩小您的code时提示。

In the above sample code I used parameters aliasing, which I suggest in order to avoid issues when minifying your code.
