我有一个 angular.js 应用程序,我需要做 CORS 请求。

我想使用角度资源定义我的休息服务“角度”,如下所述:http: //docs.angularjs.org/tutorial/step_11

但我还没有找到让这个工作的方法。在谷歌上,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 和其他服务

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 与使用 $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'});
  });

这是来自工作请求的标头(来自 chrome devtools):

这些是来自不工作请求的标头:

使用角度资源时,请求 url 看起来是错误的。但为什么?

谢谢!

URL$resource接受使用冒号作为参数。因此,在 url 中使用端口时,您需要为端口转义冒号。这在$resource 文档中进行了解释
