Post JSON Object RestSharp v107 - json

Question

I have to post this json data:
JSON.stringify(dataRest) is:
{"Ds_MerchantParameters":"eyJEU19NRVJDSEFOVF9BTU9VTlQiOiI3Myw4NCIsIkRTX01FUkNIQU5UX0NVUlJFTkNZIjoiOTc4IiwiRFNfTUVSQ0hBTlRfTUVSQ0hBTlRDT0RFIjoiMzUyNDM0NDM1IiwiRFNfTUVSQ0hBTlRfT1JERVIiOiIwMDAwMDAwMDA3NjUiLCJEU19NRVJDSEFOVF9JRE9QRVIiOiIxODExNzViOTBjNDM2ZDNlZDQ3ODg4OWEyMjdjNjI2Yjc0MDBiOTEyIiwiRFNfTUVSQ0hBTlRfVEVSTUlOQUwiOiIxIiwiRFNfTUVSQ0hBTlRfVFJBTlNBQ1RJT05UWVBFIjoiMCJ9","Ds_Signature":"X5IoP/ssIy+8gBFbD9znLoz4dFOH/mWRjMCaE/8kq65XJJVLywT05wVXE4Fqbbo6","Ds_SignatureVersion":"HMAC_SHA256_V1"}
To this endpoint https://sis-t.redsys.es:25443/sis/rest/trataPeticionREST
Using RestSharp (v107) (or httpclient).
I post above data to my api LaunchRequest via ajax:
$.ajax({
method: 'POST',
url: localhost + 'api/Redsys/LaunchRequest',
contentType: 'application/json',
data: JSON.stringify(dataRest)
}).done(function (response) {
console.log(response);
}).fail(function (error) {
console.error(error.status + '\n' + error.responseText);
});
This is the api that receive the above data and launch request to the endpoint:
[HttpPost("LaunchRequest")]
public async Task<string> LaunchRequest(DataRest dataRest)
{
string strDataRest = JsonConvert.SerializeObject(dataRest);
var client = new RestClient("https://sis-t.redsys.es:25443/");
var request = new RestRequest("sis/rest/trataPeticionREST", Method.Post);
request.RequestFormat = DataFormat.Json;
request.AddBody(strDataRest);
var response = await client.ExecuteAsync(request);
if (response.IsSuccessful)
{
return response.Content;
}
else
{
return response.ErrorMessage;
}
}
What is wrong?
Allways receive this message:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. (sis-t.redsys.es:25443)
Thank you in advance for your help.
I think one of my mistakes is serialize dataRest.
LaunchRequest should be like this:
[HttpPost("LaunchRequest")]
public async Task<string> LaunchRequest(DataRest dataRest)
{
var client = new RestClient("https://sis-t.redsys.es:25443/");
var request = new RestRequest("sis/rest/trataPeticionREST", Method.Post);
request.RequestFormat = DataFormat.Json;
request.AddBody(dataRest);
var response = await client.ExecuteAsync(request);
if (response.IsSuccessful)
{
return response.Content;
}
else
{
return response.ErrorMessage;
}
}
I don't know if the steps I follow in LaunchRequest are correct, but anyway I always get this error message:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. (sis-t.redsys.es:25443)
Thank you very much again for the help you can give me.

Answer 1

Your issue is most probably not related to RestSharp as it looks like a connection issue between the host running your API, and the external API host.
From the other issues, I am not sure why you deserialize the object just to serialize it back. You can just do this:
var request = new RestRequest("sis/rest/trataPeticionREST", Method.Post);
request.AddJsonBody(dataRest);
You also need to avoid creating the client for each request. Create a single client instance in the controller's constructor.
It's all described in the documentation by the way.
