Socket.IO CORS 请求失败

Question

我在客户端有一个角度模块：

angular.module('App')
  .factory('socketClient', function(socketFactory, Auth) {

    // socket.io now auto-configures its connection when we ommit a connection url
    var ioSocket = io('', {
      // Send auth token on connection
      query: 'token=' + Auth.getToken(),
      path:  '/socket.io-client'
    });

    return socketFactory({
    ioSocket: ioSocket
  });;
  });

如果我想请求其他命名空间，我会进行下一个更改：

    var ioSocket = io('/test', {
      // Send auth token on connection
      query: 'token=' + Auth.getToken(),
      path:  '/socket.io-client'
    }

但是当我这样做时，我会在浏览器中获得以下登录信息。

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost/socket.io-client/?token=&EIO=3&transport=polling&t=1432867748704-8. (Reason: CORS request failed).

我只是在连接到命名空间时收到此错误。

对不起我的英语。 c:

我通过以下方式解决了这个问题：

angular.module('App')
.factory('socketClient', function(socketFactory, $window) {

  // with the full path: $window.location.origin + '/test'
  var ioSocket = io($window.location.origin + '/test', {
    // Send auth token on connection
    query: 'token=' + Auth.getToken(),
    path:  '/socket.io-client'
  });

  return socketFactory({
    ioSocket: ioSocket
  });
});
