我正在尝试使用angularjs请求jason文件。我正在使用yeoman。这是我的3个文件。

在视图文件夹中：main.html

<div class="jumbotron">


Choose A Category1
 <div class="wrap" ng-controller="MainCtrl">
<select ng-model="selectedValue" ng-change="loadData()" >
  <option value="1">Category 1</option>
  <option value="2">Category 2</option>
  <option value="3">Category 3</option>
  <option value="4">Category 4</option>
  <option value="5">Category 5</option>
</select>



<div ng-show="selectedValue != null" class="main">
  <center><h2>Results For Category  {{ selectedValue }}</h2></center> <br><br>

</div>


<div  class="main"  >
  <ul class="cloudlist">
    <li class="service" ng-repeat="item in services" ng-click="select(item)">
      <div class="info">

        <h3>{{item.service_name}}</h3>
        <b>{{item.status_page}}</b><br>
        <b>Is Billed : {{item.is_billed.billing_term._identifier}}</b>


      </div>
    </li>
  </ul>
  <br>
</div>

</div>

在controllers文件夹中：main.js

'use strict';


angular.module('frontendApp')
.controller('MainCtrl', ['$scope', '$http','Services', function ($scope, $http, Services) {
    $scope.loadData = function () {
        $scope.services = Services.query();
    };






$scope.select = function (item) {
       // do something with the item here when the service is clicked  
  };


}]);

在services文件夹中：services.js

'use strict';

angular.module('frontendApp').factory('Services', function($resource) {
  return $resource('/services/:serviceId', {
    serviceId: '@_id'
  }, {});
});

我得到一个错误

错误：[$ injector：unpr]未知提供程序：ServicesProvider <-服务< -MainCtrl http://errors.angularjs.org/1.3.15/ $ injector / unpr？p0 = ServicesProvider％20％3C-％20Services％20％ 3C-％20MainCtrl minErr / <@ http：// localhost：9000

解决方案：当我使用yeoman时，我忘记了执行命令 yo angular:service Services

在您的main.js中尝试此代码

var module = angular.module('frontendApp', ['ngResource']);

module.factory('MyServices', ['$resource', function($resource) {
    return $resource('/services/:serviceId', {
        serviceId: '@_id'
    }, {});
}]);

module.controller('MainCtrl', ['$scope', '$http','MyServices', function ($scope, $http, MyServices) {
    $scope.loadData = function () {
        $scope.services = MyServices.query();
    };
}]);
