json - Consuming a ServiceStack service to get Raw Bytes -

I am enjoying a comfortable service with service service framework. Now I want to get raw bytes. Let's say that the URL is

It seems that the method is being used but I have used the post method.

Edit:

I used the code

  `var x =" http: // xx. Xxx Xxx.xx / Myservice / api / hello ".PostJsonToUrl (New MyRequestDTO () {RequestData = hello}). ToArray ();   
 I received raw bytes. However, compared with the method, about 200 bytes have been lost.  
 Using the RestSharp method, the code is:  
  var aResponse = restClient.Execute (MyRequestDTO); Byte [] bytes = a response. Robates;    
 
 
 Displays how raw bytes you can use:  
  byte [] feedbackbites = clients. Get & lt; Byte [] & gt; ("/ Poco / world"); Var DTO = Responses. FruitUtF 8 Bits () By jonathan & lt; Pococortes & gt; (); Dto.Result // hello, world   
 or as a stream:  
 using  (stream responseflow = client.get & lt; Stream & gt; ("/ poco / world")) {var dto = responsestream.ReadFully () .Utf8Bytes () Jason & lt; PocoResponse & gt; (); Dto.Result // Hello, World}   
 You do not have to use Type client to get raw bytes, you can easily use it: < / P> 
  byte [] Raw Bows = "http://example.org/Myservice/api/hello" .GetBytesFromUrl ();   
 How to recover a byte by posting JSON and using HTTP utility extensions  
  var dtoBytes = new MyRequestDTO {...}. ToJson (). ToUtf8Bytes (); Var responsebits = "http://example.org/Myservice/api/hello". PostBytes TUURL (DTOBET, Content Type: "App / JS");
