Java 使用 Netty DefaultFullHttpRequest 實現Post發送數據包的功能

		// 向SQLMAPAPI傳送開始測試的指令
		NioEventLoopGroup workerGroup = new NioEventLoopGroup();
		try {
			Bootstrap bootstrap = new Bootstrap();
			bootstrap.group(workerGroup).channel(NioSocketChannel.class).option(ChannelOption.SO_KEEPALIVE, true)
					.handler(new ChannelInitializer<SocketChannel>() {
						@Override
						protected void initChannel(SocketChannel socketChannel) throws Exception {
							socketChannel.pipeline().addLast(new HttpRequestEncoder());// 客戶端對發送的httpRequest進行編碼
							socketChannel.pipeline().addLast(new HttpResponseDecoder());// 客戶端需要對服務端返回的httpresopnse解碼
							socketChannel.pipeline().addLast(new StartTestResponse());
						}
					});

			Channel channel = bootstrap.connect("127.0.0.1", 8775).sync().channel();

			URI uri = new URI("/scan/" + taskid + "/start");

            // *** 設置POST數據包中傳輸的數據 ***
