如何使用angular.js-resource启用cors请求

angularjs

我有一个angular.js应用程序,我需要做CORS请求。

我想使用以下角度资源定义我的休息服务“角度”:http :
//docs.angularjs.org/tutorial/step_11。

但是我还没有找到一种方法来使它工作。在google上,我找到了以下示例代码:http
:
//jsfiddle.net/ricardohbin/E3YEt/,但这似乎不适用于angular-
resources。

这是我的app.js

'use strict';

angular.module('corsClientAngularApp', ['helloServices'])
  .config(function ($routeProvider) {
    $routeProvider
      .when('/', {
        templateUrl: 'views/main.html',
        controller: 'MainCtrl'
      })
      .otherwise({
        redirectTo: '/'
      });
  });

这是我的services.js和其余的服务

angular.module('helloServices', ['ngResource']).
    factory('Hello', function($resource){
  return $resource('http://localhost:8080/cors-server/hello/:name', {}, {
    query: {method:'GET', params:{name:'name'}, isArray:false}
  });
});

这是我的main.js和使用$ http的控制器,这有效!

'use strict';

angular.module('corsClientAngularApp')
  .controller('MainCtrl', function ($scope, $http, Hello) {
    $http.defaults.useXDomain = true;


    $http.get('http://localhost:8080/cors-server/hello/stijn')
        .success(function(data) {
            $scope.hello = data;
        });
  });

这是我使用角度资源的main.js的另一个版本。这不起作用:(

'use strict';

angular.module('corsClientAngularApp')
  .controller('MainCtrl', function ($scope, $http, Hello) {
    $http.defaults.useXDomain = true;
    $scope.hello = Hello.query({name:'stijn'});
  });

这是工作请求的标题(来自chrome devtools):

Request URL:http://localhost:8080/cors-server/hello/stijn
Request Method:OPTIONS
Status Code:200 OK

这些是NOt工作请求中的标头:

使用angular-resources时,请求网址似乎是错误的。但为什么?

谢谢!

$resource使用冒号作为参数接受的URL 。因此,在url中使用port时,您需要将冒号转义为port。在$ resource
docs中
对此进行了解释
