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draft-17。有人能告诉我，如何设置客户端使用此协议？

我有这段代码：

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

         //some functions
      },options);

问候

更新在我的服务器上，我在版本8.1中使用Jetty。

更新 LogCat的输出是：

您指的是WebSocket协议版本还是WebSocket子协议？

关于前者：AutobahnAndroid实现RFC6455（最后和最终的WebSocket协议版本）。没有办法降级到旧版本，但基本上，从Hybi-10 +到RFC6455没有发生重大变化。

关于后者：在打开像this这样的WebSocket连接时指定了WebSocket子协议。
