android - 高速公路异常 WebSockets 协议(protocol)违规

Question

在我的 android 应用程序中，我想使用高速公路库来使用 websockets。

我认为服务器正在使用 draft-17。谁能告诉我如何设置客户端以使用此协议(protocol)？

我有这个代码:

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

         //some functions
      },options);

问候

更新在我的服务器上，我使用 8.1 版的 Jetty。

更新LogCat 的输出是:

您指的是 WebSocket 协议(protocol)版本还是 WebSocket 子协议(protocol)？

关于前者:AutobahnAndroid 实现了 RFC6455(最后也是最终的 WebSocket 协议(protocol)版本)。没有办法降级到旧版本，但基本上，从 Hybi-10+ 到 RFC6455 没有重大变化。

关于后者:在打开 WebSocket 连接时指定 WebSocket 子协议(protocol)，如 this .
