How to POST request using RestSharp

Question

I m trying to POST the request using RestSharp client as follows I m passing the Auth Code to following function

public void ExchangeCodeForToken(string code) {     if (string.IsNullOrEmpty(code))     {         OnAuthenticationFailed();     }     else     {                    var request = new RestRequest(this.TokenEndPoint, Method.POST);         request.AddParameter("code", code);         request.AddParameter("client_id", this.ClientId);         request.AddParameter("client_secret", this.Secret);         request.AddParameter("redirect_uri", "urn:ietf:wg:oauth:2.0:oob");         request.AddParameter("grant_type", "authorization_code");         request.AddHeader("content-type", "application/x-www-form-urlencoded");          client.ExecuteAsync<AuthResult>(request, GetAccessToken);     } }  void GetAccessToken(IRestResponse<AuthResult> response) {     if (response == null || response.StatusCode != HttpStatusCode.OK                          || response.Data == null                           || string.IsNullOrEmpty(response.Data.access_token))     {         OnAuthenticationFailed();     }     else     {         Debug.Assert(response.Data != null);         AuthResult = response.Data;         OnAuthenticated();     } } 

But i am getting response.StatusCode = Bad Request. Can anyone help me for how do i POST the request using Restsharp client.

Answer 1

My RestSharp POST method:

var client = new RestClient(ServiceUrl);  var request = new RestRequest("/resource/", Method.POST);  // Json to post. string jsonToSend = JsonHelper.ToJson(json);  request.AddParameter("application/json; charset=utf-8", jsonToSend, ParameterType.RequestBody); request.RequestFormat = DataFormat.Json;  try {     client.ExecuteAsync(request, response =>     {         if (response.StatusCode == HttpStatusCode.OK)         {             // OK         }         else         {             // NOK         }     }); } catch (Exception error) {     // Log }

This way works fine for me:

var request = new RestSharp.RestRequest("RESOURCE", RestSharp.Method.POST) { RequestFormat = RestSharp.DataFormat.Json }                 .AddBody(BODY);  var response = Client.Execute(request);  // Handle response errors HandleResponseErrors(response);  if (Errors.Length == 0) { } else { } 

Hope this helps! (Although it is a bit late)
