netty v3.9.4
做了个netty接websocket的例子，但是请求类型判断始终是HttpRequet，没有WebSocketFrame请求，结果是这样的：
message:class org.jboss.netty.handler.codec.http.DefaultHttpRequest
HttpRequest uri:/websocket
HttpRequest method:GET
message:class org.jboss.netty.handler.codec.http.DefaultHttpRequest
HttpRequest uri:/web4/http11client.jsp?q=a11
HttpRequest method:GET

Object message = e.getMessage();
System.out.println("message:"+message.getClass());
if(message instanceof WebSocketFrame){
if(message instanceof TextWebSocketFrame){
TextWebSocketFrame req = (TextWebSocketFrame) message;
System.out.println("wsRequest text:"+req.getText());
}
}else if(message instanceof HttpRequest){
HttpRequest req = (HttpRequest) message;
System.out.println("HttpRequest uri:"+req.getUri());
System.out.println("HttpRequest method:"+req.getMethod());
}
}
