Http Post 二进制通信

客户端请求和接收（使用了httpclient4.3 和netty3.5）

public static void httpPost11() {
    CloseableHttpClient httpClient = HttpClients.createDefault();
    HttpPost httpPost = new HttpPost(
            "http://192.168.1.74:4321/v1/user/get_notice");
    MultipartEntityBuilder d=MultipartEntityBuilder.create();
    int a=10,b=11;
    d.addBinaryBody("id", HighLowByteConvert.toHH(a));
    d.addBinaryBody("ids", HighLowByteConvert.toHH(b));
    try {
        httpPost.setEntity(d.build());
        CloseableHttpResponse httppHttpResponse2 = httpClient
                .execute(httpPost);
        if (httppHttpResponse2.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
            byte []c=EntityUtils.toByteArray(httppHttpResponse2.getEntity());
            ChannelBuffer channelBuffer = ChannelBuffers.copiedBuffer(c);
            System.out.println(channelBuffer.readInt());
            System.out.println(channelBuffer.readInt());
        }
        else
        {
        }
        httppHttpResponse2.close();
        httpClient.close();
    } catch (Exception e) {
        e.printStackTrace();
    }

}

服务端接收和发送

public void handle(HttpRequest request, Channel channel) throws Exception {
        
        HttpMethod method = request.getMethod();
        if(method.equals(HttpMethod.GET)){
            handle(request.getUri(), channel);
        }else if(method.equals(HttpMethod.POST)){
             HttpPostRequestDecoder decoder = new HttpPostRequestDecoder(new DefaultHttpDataFactory(false), request);
             List< InterfaceHttpData> datas = decoder.getBodyHttpDatas();
             for (InterfaceHttpData interfaceHttpData : datas) {
                 if(interfaceHttpData.getHttpDataType() == HttpDataType.Attribute)
                 {
                     Attribute attribute = (Attribute) interfaceHttpData;
                     System.out.println("id :" +   attribute.getChannelBuffer().readInt());
                 }
            }
             sendResponse("", channel);
        }
    }

protected void sendResponse(String contextString, Channel channel){
        
        HttpResponse response = new DefaultHttpResponse(HTTP_1_1, HttpResponseStatus.OK);
        ChannelBuffer channelBuffer = ChannelBuffers.dynamicBuffer();
        channelBuffer.writeInt(1);
        channelBuffer.writeInt(2);
        response.setContent(channelBuffer);
        response.setHeader(CONTENT_TYPE, "text/plain; charset=UTF-8"); //application/octet-stream 也可以
        channel.write(response).addListener(ChannelFutureListener.CLOSE);
    }
