    使用ws作为websocket的server，在onconnect的回调中返回一个WebSocket对象，现在需要针对每个连接上来的WebSocket对象处理，自己创建了一个Conn的对象，用于解析协议并处理。

    那怎么把回调里的WebSocket和自己的Conn关联起来呢？这样在下一次回调的时候，直接就可以访问到Conn了。一般c/c++的方法可以通过set_user_data()和get_user_data()来设置和获取，那node里怎么做？直接用 ws.cOnn= new Conn()？

    我怎么知道原来有没有ws.conn呢？

    有什么好的方法吗？
  • conn
  • ws
  • WebSocket

    额，是不是通过闭包就可以了？

    ws.on("connection",function(ws) {
    cOnn= new Conn(ws)
    ws.on("message",function("message") {
    conn.handleMessage(message);
    })
    })
