Add a GET parameter to a POST request with RestSharp

Question

I want to make a POST request to a URL like this:

http://localhost/resource?auth_token=1234

And I

Answer 1

The current version of RestSharp has a short method that makes use of a template:

var request = new RestRequest("resource?auth_token={token}", Method.POST);
request.AddUrlSegment("token", "1234");

Alternatively, you can add a parameter without a template:

var request = new RestRequest("resource", Method.POST);
request.AddQueryParameter("auth_token", "1234); 

or

var request = new RestRequest("resource", Method.POST);
request.AddParameter("auth_token", "1234", ParameterType.QueryString); 

Answer 2

This should work if you 1) add the token to the resource url and 2) specify ParameterType.UrlSegment like this:

var client = new RestClient("http://localhost");
var request = new RestRequest("resource?auth_token={authToken}", Method.POST);
request.AddParameter("auth_token", "1234", ParameterType.UrlSegment);    
request.AddBody(json);
var response = client.Execute(request);

This is far from ideal - but the simplest way I've found... still hoping to find a better way.
