Netty服务器接收两个单独的请求而不是一个

Question

我正在制作一台Netty Http服务器，而且我遇到了一个问题。每当我从浏览器或java程序发送请求时，它都会发送两次（是的，我在我的管道中使用HttpObjectAggregator。）例如：

INFO: [id: 0x8f2a1b64, L:/0:0:0:0:0:0:0:0:8080] READ: [id: 0x006ab104, L:/0:0:0:0:0:0:0:1:8080 - R:/0:0:0:0:0:0:0:1:62690]

这一切都来自一个浏览器请求。

这是我的处理程序channelRead方法：

public void channelRead0(ChannelHandlerContext ctx, Object msg) { // (2)

        if(!(msg instanceof HttpRequest)) {
            System.out.println("not http");
            System.out.println(msg.toString());
            System.out.println(msg.getClass());
            //ctx.write("hi");
            return;
        }

        HttpRequest request = (HttpRequest) msg;
        QueryStringDecoder queryStringDecoder = new QueryStringDecoder(request.getUri());

        Map<String, java.util.List<String>> params = queryStringDecoder.parameters();
        try {
        System.out.println("message: "+ params.get("message").get(0));
        }catch(Exception e) {
            //e.printStackTrace();
            System.out.println("no message");
        }

        ByteBuf bytes = Unpooled.copiedBuffer("test", CharsetUtil.UTF_8);
        DefaultFullHttpResponse resp = new DefaultFullHttpResponse(HttpVersion.HTTP_1_1, HttpResponseStatus.OK,bytes);
        resp.headers().set(HttpHeaderNames.CONTENT_TYPE, "text/plain; charset=UTF-8");
        //resp.addHeader(, buffer.readableBytes());
      //ctx.writeAndFlush("hi");
      //ChannelFuture cf=ctx.writeAndFlush(Unpooled.copiedBuffer("Ack", CharsetUtil.UTF_8));
        System.out.println(msg+"s");
        HttpUtil.setContentLength(resp, 4);
        ChannelFuture cf=ctx.writeAndFlush(resp);
        System.out.println("Send failed2: " + cf.cause());
    }

这真让我难过，所以任何帮助都会非常感激。如果我需要提供更多代码，请告诉我。

编辑：

这是我的管道：

          //p.addLast(new HttpRequestDecoder());
          // Uncomment the following line if you don't want to handle HttpChunks.
          p.addLast(new HttpServerCodec());
          p.addLast(new HttpObjectAggregator(1048576));

          //p.addLast(new HttpResponseEncoder());
          // Remove the following line if you don't want automatic content compression.
          //p.addLast(new HttpContentCompressor());
          p.addLast(new Handler());
