How to access the HTTP request body using RestSharp?
The request body is a type of parameter. To add one, you can do one of these...
req.AddBody(body);
req.AddBody(body, xmlNamespace);
req.AddParameter("text/xml", body, ParameterType.RequestBody);
req.AddParameter("application/json", body, ParameterType.RequestBody);
To retrieve the body parameter you can look for items in the req.Parameters
collection where the Type
is equal to ParameterType.RequestBody
.
See code for the RestRequest
class here.
Here is what the RestSharp docs on ParameterType.RequestBody
has to say:
If this parameter is set, it’s value will be sent as the body of the request. The name of the Parameter is ignored, and so are additional RequestBody Parameters – only 1 is accepted.
RequestBody only works on POST or PUT Requests, as only they actually send a body.
If you have GetOrPost parameters as well, they will overwrite the RequestBody – RestSharp will not combine them but it will instead throw the RequestBody parameter away.
For reading/updating the body parameter on-the-fly, you can try:
var body = req.Parameters.FirstOrDefault(p => p.Type == ParameterType.RequestBody);
if (body != null)
{
Console.WriteLine("CurrentBody={0}", body.Value);
body.Value = "NewBodyValue";
}
Or failing that, create a new copy of the RestRequest
object with a different body.

I'm building a RESTful API client in C# .NET 3.5.
I first started building it with the good old
HttpWebClient
(andHttpWebResponse
), I could do whatever I wanted with. I were happy. The only thing I was stuck on was the automatic deserialization from JSON response.So, I've heard about a wonderful library called RestSharp (104.1) which eases the development of RESTful API clients, and automatically deserialize JSON and XML responses. I switched all my code on it, but now I realize I can't do things I could do with
HttpWebClient
andHttpWebResponse
, like access and edit the raw request body.Anyone has a solution ?
Edit : I know how to set the request body (with
request.AddBody()
), my problem is that I want to get this request body string , edit it, and re-set it in the request (updating the request body on the fly) -

.Where([lambda]).FirstOrDefault()
you can simply do.FirstOrDefault([lambda])

req.JsonSerializer.Serialize(request.Parameters[1])
