compile 'org.msgpack:msgpack-core:+'

获取网络数据

OkHttpClient okHttpClient = new OkHttpClient();
        //构建一个请求对象
        Request request = new Request.Builder().url("https://b.yipinxiaobai.com/api/testmsgpack").build();
        //发送请求
        try {
            Response response = okHttpClient.newCall(request).execute();
// 请求下来的数据          response.body().bytes()  
MessageUnpacker unpacker = MessagePack.newDefaultUnpacker(response.body().bytes());
                Map<Value, Value> v = unpacker.unpackValue().asMapValue().map();
//id map 的key
//v.get(newString("id")).asStringValue().toString() map 的value
LogUtil.e("id", v.get(newString("id")).asStringValue().toString());
//big_cat map 的key
//v.get(newString("big_cat")).asStringValue().toString() map 的value               
 LogUtil.e("big_cat", v.get(newString("big_cat")).asStringValue().toString());
            unpacker.close();

        } catch (IOException e) {
            e.printStackTrace();
        }
