Question

我想同时支持ws和http，但仍然坚持这个问题。我尝试访问/，但netty回复了带有消息的http 400。

不是WebSocket握手请求：缺少升级

这是来自Chrome浏览器的http://localhost:9001/请求的日志。

和代码段。

p.addLast(new HttpServerCodec())
        .addLast(new HttpObjectAggregator(65536))
        .addLast( new LoggingHandler(LogLevel.INFO))
        /**
         * For websocket chatting
         */
        .addLast(new WebSocketServerProtocolHandler("/chat"))
        .addLast(new WsUserAcceptHandler())
        .addLast(new WsChatServerHandler())
        /**
         * For accessing / or HTTP 404 
         */
        .addLast(new HttpStaticFileHandler("/", ChatServer.index))
        .addLast(new HttpNotFoundHandler());

在这个日志行中，我不明白为什么netty试图进行websocket握手？

io.netty.handler.codec.http.websocketx.WebSocketServerHandshaker[debug:81] - [id: 0xd2bd692e, L:/0:0:0:0:0:0:0:1:9001 - R:/0:0:0:0:0:0:0:1:53677] WebSocket version V00 server handshake
