如何在Netty 3.3中配置WebSockets（RFC 6455）？

我有Netty 3.3服务器与WebSockets从https://github.com/netty/netty/tree/3.2/src/main/java/org/jboss/netty/example/http/websocketx/server 如何在Netty 3.3中配置WebSockets（RFC 6455）？

我有客户端实现RFC 6455，但服务器无法解码它的默认消息。在调试时，我看到使用了WebSocket08FrameDecoder（而不是WebSocket13FrameDecoder）。当我将客户端降级到draft00时，一切正常。如何配置Netty来解码RFC 6455消息？

更新

客户端发送此握手包：

GET /websocket HTTP/1.1 
Upgrade: WebSocket 
Connection: Upgrade 
Sec-WebSocket-Version: 13 
Sec-WebSocket-Key: 5a087 
Host: 127.0.0.1 
Origin: 127.0.0.1

和服务器上的handshaker是WebSocketServerHandshaker13，但我仍然得到错误：

如果你在看WebSocketServerHandshakerFactory，它实现了基于HTTP头中传递的Web套接字版本的解码器。

public WebSocketServerHandshaker newHandshaker(HttpRequest req) { 

    String version = req.getHeader(Names.SEC_WEBSOCKET_VERSION); 
    if (version != null) { 
     if (version.equals(WebSocketVersion.V13.toHttpHeaderValue())) { 
      // Version 13 of the wire protocol - RFC 6455 (version 17 of the draft hybi specification). 
      return new WebSocketServerHandshaker13(webSocketURL, subprotocols, allowExtensions); 
     } else if (version.equals(WebSocketVersion.V08.toHttpHeaderValue())) { 
      // Version 8 of the wire protocol - version 10 of the draft hybi specification. 
      return new WebSocketServerHandshaker08(webSocketURL, subprotocols, allowExtensions); 
     } else { 
      return null; 
     } 
    } else { 
     // Assume version 00 where version header was not specified 
     return new WebSocketServerHandshaker00(webSocketURL, subprotocols); 
    } 
}

请检查您的客户端实施，以查看它在HTTP标头中发送的版本。它应该是Sec-WebSocket-Version: 13。

我添加客户端握手包和调试日志来回答 – Quiz

它应该是在客户端掩码问题。感谢您的答复。 – Quiz
