如何使用 angular.js-resource 启用 cors 请求 [英] How to enable cors request with angular.js-resource

问题描述

我有一个 angular.js 应用程序，我需要执行 CORS 请求.

I have an angular.js application and i need to do CORS request.

我想使用角度资源定义我的休息服务角度"，描述如下:http://docs.angularjs.org/tutorial/step_11.

I want to define my rest services "the angular" using angular resources, described here: http://docs.angularjs.org/tutorial/step_11.

但我还没有找到让它工作的方法.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.

But i haven't found a way to get this working. On google i found the following sample code: http://jsfiddle.net/ricardohbin/E3YEt/, but this seems not to work with angular-resources.

这是我的 app.js

this is my 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

this is my services.js with the rest services

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，控制器使用 $http，这是有效的！:

This is my main.js with the controller using the $http, this works!:

'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;
        });
  });

这是我的 main.js 的另一个版本，使用 angular 资源.这不起作用:(

This is another version of my main.js using angular resources. This does NOT work :(

'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):

This is are the headers from the working request (from chrome devtools):

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

Request Headers
Accept:*/*
Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0.3

这些是来自不工作请求的标头:

And these are the headers from the NOt working request:

使用 angular-resources 时，请求 url 似乎是错误的.但为什么?

It looks like the request url is wrong when using angular-resources. But why?

谢谢！

推荐答案

$resource 的 URL 接受使用冒号作为参数.因此，在 url 中使用 port 时，您需要为 port 转义冒号.这在 $resource 文档

URL for $resource accepts using colon for parameters. Therefore when using port in url you need to escape the colon for port. This is explained in $resource docs
