Question

我正在使用Ratchet WebSockets和Autobahn.js进行双向客户端 - 服务器通信。我已经安装了所有东西，打开了端口，这已经是几周了（是的，确实是几个星期），它仍然无法正常工作。我想我已经把它缩小到Autobahn的订阅方法不能正常工作。

我正在使用的是稍微修改此处的示例代码：

http://socketo.me/docs/push

这是我的客户代码：

<script>
    window.define = function(factory) {
        try{ delete window.define; } catch(e){ window.define = void 0; } // IE
        window.when = factory();
    };
    window.define.amd = {};
</script>
<script src="/apps/scripts/when.js"></script> 
<script src="http://autobahn.s3.amazonaws.com/js/autobahn.min.js"></script>
<script>
    var conn = new ab.Session(
        'ws://light-speed-games.com:8080' // The host (our Ratchet WebSocket server) to connect to
      , function() {            // Once the connection has been established
            console.log('Connection established.');
            conn.subscribe('kittensCategory', function(topic, data) {
                // This is where you would add the new article to the DOM (beyond the scope of this tutorial)
                console.log('New article published to category "' + topic + '" : ' + data.title);
            });
        }
      , function() {            // When the connection is closed
            console.warn('WebSocket connection closed');
        }
      , {                       // Additional parameters, we're ignoring the WAMP sub-protocol for older browsers
            'skipSubprotocolCheck': true
        }
    );
</script>

我认为问题出在这里：

function() {            // Once the connection has been established
                console.log('Connection established.');
                conn.subscribe('kittensCategory', function(topic, data) {
                    // This is where you would add the new article to the DOM (beyond the scope of this tutorial)
                    console.log('New article published to category "' + topic + '" : ' + data.title);
                });
            }

行console.log('Connection established.');完成其工作 - 它在控制台中记录其消息。但是，conn.subscribe方法不执行任何操作。如果我将kittensCategory更改为任何其他字符串并不重要，它仍然无效。但是kittensCategory是唯一有意义的东西（通过上面的链接看Ratchet的示例代码）。

有什么想法吗？

Autobahn.js - subscribe不适用于websockets
