netty与cocos creator交互

一直没有写过服务器,练习一下服务器开发的流程和思想。

        ChannelPipeline pipeline = ch.pipeline();
        if (sslCtx != null) {
            pipeline.addLast(sslCtx.newHandler(ch.alloc()));
        }
        pipeline.addLast(new HttpServerCodec());
        pipeline.addLast(new HttpObjectAggregator(65536));
        pipeline.addLast(new WebSocketServerCompressionHandler());
        pipeline.addLast(new WebSocketServerProtocolHandler(WEBSOCKET_PATH, null, true));
        pipeline.addLast(new WebSocketIndexPageHandler(WEBSOCKET_PATH));
        pipeline.addLast(new WebSocketFrameHandler());

通过http进行注册,webscocket登录与服务器交互。

先启动minesweep服务之后再启动gate服务

gate服务会发送一个命令号给minesweep,双方持有各自的ctx，从而实现远程调用。

gate维护与服务端的链接,如果查找不到新消息的命令号就转发给clinet的远程node;

    public void processMessage(ChannelHandlerContext ctx , String msg )
    {
        try
        {
            JSONObject jo = new JSONObject(msg);
            int cmdID = jo.getInt("cmdID");
            MsgHander handle = null;
            switch (cmdID)
            {
                case USER_LOGIN:
                    handle = new LoginHandler(ctx,msg);
                    break;
                case ENTER_MINESWEEP:
                    enterGame(ENTER_MINESWEEP,ctx);
                    break;
                case RCP:
                    handle = nodeToClientMsg(jo);
                    break;
                case BACK_HALL:
                    handle = backHall(jo);
                    break;
                default:
                    handle = clientToNodeMsg(ctx,jo);
                    break;
            }
            Worker.dispath(handle);
        }
        catch (JSONException e)
        {
            System.out.print(e.getStackTrace());
        }
    }

minesweep服务

                        public void initChannel(SocketChannel ch) throws Exception {
                            ChannelPipeline pipeline = ch.pipeline();
                            ByteBuf[] by = new ByteBuf[]{ Unpooled.wrappedBuffer(new byte[]{0})};
                            pipeline.addLast("frameEncoder",new LengthFieldPrepender(4));
                            pipeline.addLast("encoder", new StringEncoder(Charset.forName("UTF-8")));
                            pipeline.addLast("frameDecoder",new LengthFieldBasedFrameDecoder(1048576,0,4,0,4));
                            pipeline.addLast("decoder", new StringDecoder(Charset.forName("UTF-8")));
                            pipeline.addLast(new ServerHandler());
                        }

用netty自带的编码解码器,frameEncoder 和 frameDecoder负责分包。

消息处理

    public void processMessage(ChannelHandlerContext ctx , String msg )
    {
        try
        {
            JSONObject jo = new JSONObject(msg);
            int cmdID = jo.getInt("cmdID");
            switch (cmdID)
            {
                case ENTER_MINESWEEP:
                    enterGame(jo.getJSONObject("data"));
                    break;
                case READY_ROOM:
                    readyRoom(jo.getJSONObject("data"));
                    break;
                case KICK_PLAYER:
                    kickPlayer(KICKED_BY_OTHER,jo.getJSONObject("data"));
                    break;
                case EXIT_ROOM:
                    kickPlayer(KICKED_BY_SELF,jo.getJSONObject("data"));
                    break;
                case SELECT_GIRD:
                    selectGird(jo.getJSONObject("data"));
                    break;
                default:
                    break;
            }
        }
        catch (JSONException e)
        {
            System.out.print(e.getStackTrace());
        }
    }

客服端creator通过Notification注册命令号对应的处理。

接下来还是应该深入图形渲染。
