Autobahn异常WebSockets协议违反

Question

在我的android应用程序中，我想使用autobahn库来使用websockets。

我认为服务器正在使用草案-17。有人能告诉我，如何设置客户端来使用这个协议吗？

我有这样的代码：

      mConnection.connect(url,new String[] {"protocolname?"}, new WebSocketHandler() {

         //some functions
      },options);

问候

在我的服务器上使用更新，在8.1版中使用Jetty。

UPDATE LogCat的输出是：

Answer 1

您指的是WebSocket协议版本还是WebSocket子协议？

对于前者: AutobahnAndroid实现了RFC6455 (最后也是最后一个WebSocket协议版本)。没有办法降级到旧版本，但基本上，没有重大的变化，从Hybi-10+到RFC6455。

关于后者: WebSocket子协议是在打开WebSocket连接时指定的，比如这。
