Consuming a ServiceStack service to get Raw Bytes - json

Question

I'm consuming a rest service with ServiceSatck framework. Now I want to get the raw bytes.
Suppose the url is http://xx.xxx.xxx.xx/Myservice/api/hello.
In this Seeing the Http Response content in ServiceStack it seems to be using get method but I used post method.
EDIT:
I used the code
`var x = "http://xx.xxx.xxx.xx/Myservice/api/hello".PostJsonToUrl(new MyRequestDTO() { RequestData = hello }).ToArray();
I did get the raw bytes. However comparing with RestSharp method, there are about 200 bytes lost.
Using RestSharp method, the code is:
var aResponse = restClient.Execute(MyRequestDTO);
byte[] bytes = aResponse.RawBytes;

The documentation for ServiceStack's typed .NET clients shows how you can access the raw bytes:
byte[] responseBytes = client.Get<byte[]>("/poco/World");
var dto = responseBytes.FromUtf8Bytes().FromJson<PocoResponse>();
dto.Result //Hello, World
Or as a Stream:
using (Stream responseStream = client.Get<Stream>("/poco/World")) {
var dto = responseStream.ReadFully().FromUtf8Bytes().FromJson<PocoResponse>();
dto.Result //Hello, World
}
You don't even need to use the type clients for getting raw bytes, you can just as easily use a HTTP Util extension method:
byte[] rawBytes = "http://example.org/Myservice/api/hello".GetBytesFromUrl();
HOW to POST JSON and retrieve bytes using HTTP Utils extensions
var dtoBytes = new MyRequestDTO { ... }.ToJson().ToUtf8Bytes();
var responseBytes = "http://example.org/Myservice/api/hello".PostBytesToUrl(
dtoBytes, contentType:"application/json");
