automate the test case to validate the response “US” when the value for the input parameter “CurrencyCode” is “USD” Using C# RestSharp

I have developed a API using RapidAPI to get and automate test cases to validate response “US” when the value for the input parameter “CurrencyCode” is “USD” Using C# RestSharp.but it is fowing an error when its opening on .net console as below on get and IRestresponse.I need help to fix it.
here is my code.
using RestSharp;
using System;
using RestSharp.Authenticators;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace IFSAPI
{
internal class Program
{
static void Main(string[] args)
{
//arrange
var client = new RestClient("https://wft-geo-db.p.rapidapi.com/v1/geo/countries?currencyCode=LKR");
var request = new RestRequest(Method.GET);
//
request.AddHeader("X-RapidAPI-Key", "2ade609583msh867a2c95e9e419dp1a1668jsnf1f880a47cc5");
request.AddHeader("X-RapidAPI-Host", "wft-geo-db.p.rapidapi.com");
//act
IRestResponse response = client.Execute(request);
//var content = response.Content;
//Console.WriteLine(content);
//Console.ReadKey();
}
}
}

POST function in RestSharp

I want to POST a file to an API by RestSharp, but the Method.Post encounter error as cannot convert from 'RestSharp.Method' to 'string?', and the error for the Method.POST is 'Method' does not contain a definition for 'POST'?
using RestSharp;
using System;
using System.Net;
using System.Net.Http;
namespace UploadToAzure
{
class Program
{
static void Main()
{
var client = new RestClient("http://localhost:7071/api/Function1");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddFile("File", "/D:/sample Files/audio0001.mp3");
IRestResponse response = (IRestResponse)client.Execute(request);
Console.WriteLine(response.Content);
}
}
}
Thanks for your answers!

It solved when I add string of destination to RestRequest and change IRestResponse to RestResponse. In addition correct the path of file.
using RestSharp;
using System;
using System.Net;
using System.Net.Http;
namespace UploadToAzure
{
class Program
{
static void Main()
{
var client = new RestClient("http://localhost:7071/api/Function1");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddFile("File", #"D:/sample Files/audio0001.mp3");
RestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
}
}
}

I had similar issue, but solved it by doing the following two things
Changed POST to Post.
Putting Method.Post in double quotes "", i.e treating it as a string.

Google Sheets API v4, SocketException: An existing connection was forcibly closed by the remote host

I have gone through many solutions. I also tried one solution here, but it did not work for me. So please don't mark this one as duplicate. I am working with Google Sheets API v4, and I got the following exceptions:
System.AggregateException: 'One or more errors occurred.'
Inner Exceptions:
HttpRequestException: An error occurred while sending the request.
WebException: The underlying connection was closed: An unexpected error occurred on a send.
IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
SocketException: An existing connection was forcibly closed by the remote host
when I try to get the result of HttpResponseMessage. Below are my codes:
using System;
using System.Collections.Generic;
using System.Linq;
using System.IO;
using System.Net;
using System.Text;
using System.Net.Http;
using System.Configuration;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System.Net.Security;
using System.Net.Http.Headers;
using System.Security.Cryptography.X509Certificates;
namespace ConsoleApp3
{
static class Program
{
static string _apiKey;
static string _sheetID;
static string _baseUrl;
static HttpClient _client;
static Program()
{
_apiKey = ConfigurationManager.AppSettings["apiKey"];
_sheetID = ConfigurationManager.AppSettings["sheetID"];
_client = new HttpClient();
_client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls | SecurityProtocolType.Ssl3;
_baseUrl = "https://sheets.googleapis.com/v4/spreadsheets/{0}/values/{1}!{2}";
}
static void Main(string[] args)
{
using(HttpRequestMessage __request = new HttpRequestMessage())
{
__request.Method = HttpMethod.Post;
__request.RequestUri = new Uri(string.Format(_baseUrl, _sheetID, "Sheet1", "A1:D3"));
Dictionary<string, object> __parameters = new Dictionary<string, object>();
__parameters.Add("key", _apiKey);
__request.Content = new StringContent(__parameters.ToJson(), Encoding.UTF8, "application/json");
using (HttpResponseMessage ___response = _client.SendAsync(__request).Result) // Error Here
{
}
}
Console.ReadKey();
}
}
}

It may be an issue with URL encoding of the ":" character in your request
use System.Web.HttpUtility.UrlEncode() to make sure any characters in your sheetId, sheet name or cell location are encoded correctly.
In your code this line;
__request.RequestUri = new Uri(string.Format(_baseUrl, HttpUtility.UrlEncode(_sheetID), "Sheet1", HttpUtility.UrlEncode("A1:D3")));

Web API: FromBody always null

I'm trying to develop a web API, and when I test the POST method, the body is always null. I have tried everything when sending the request:
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:1748/api/SomeAPI");
req.Method = "post";;
var aaa = Encoding.Default.GetBytes("Test");
req.ContentType = "application/xml";
req.ContentLength = aaa.Length;
req.GetRequestStream().Write(aaa, 0, aaa.Length);
HttpWebResponse res = (HttpWebResponse)req.GetResponse();
using (System.IO.StreamReader sr = new System.IO.StreamReader(res.GetResponseStream())) {
Console.WriteLine(sr.ReadToEnd());
}
I use a breakpoint, and the API is called properly, but the body member is always null:
[HttpPost]
public void Post([FromBody]String test) {
}

try
[HttpPost]
public void SomeApi()
{
var test = HttpContext.Current.Request.Form["Test"];
}
If u send correctly the value,this will work 100%

Your Content Type is set to XML so you must pass the data as XML. This means wrapping your data in <string> element.
I would recommend using RestSharp (http://restsharp.org/) for making WebAPI calls from .Net.
var client = new RestClient("http://localhost:1748/");
var request = new RestRequest("api/SomeAPI", Method.POST);
request.AddBody("Test");
var response = client.Execute(request);
Update
I have created a sample project and it works absolutely fine:
Server side:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
namespace WebApplication1.Controllers
{
public class HomeController : ApiController
{
[Route("api/TestAPI")]
[HttpPost]
public IHttpActionResult Post([FromBody]String test)
{
return Ok(string.Format("You passed {0}.", test));
}
}
}
Client side:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:1748/api/TestAPI");
req.Method = "post"; ;
var aaa = Encoding.Default.GetBytes("\"Test\"");
req.ContentType = "application/json";
req.ContentLength = aaa.Length;
req.GetRequestStream().Write(aaa, 0, aaa.Length);
HttpWebResponse res = (HttpWebResponse)req.GetResponse();
using (System.IO.StreamReader sr = new System.IO.StreamReader(res.GetResponseStream()))
{
Console.WriteLine(sr.ReadToEnd());
}
}
}
}
After installing the WEB API service in IIS and running the console app it prints:
"You passed Test."
Please note the quotes around the response.
If you want to use XML then you need to modify the content type and data you are sending:
var aaa = Encoding.Default.GetBytes("<string xmlns=\"http://schemas.microsoft.com/2003/10/Serialization/\">Test</string>");
The response you will get is
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">You passed Test.</string>
Both samples in the debugger will have correct value passed in the test parameter.

Two things to try, 1st, try your request using a tried and tested tool like Postman. This will eliminate any chance your request is malformed in any way. 2nd, try changing your ContentType to text/plain. It's possible the request pipeline is seeing application/xml but your request body is invalid xml which really should be a bad request but is just being serialized as null.

authorization header does not have the right format

Akamai api using purge my url i got eror he authorization header does not have the right format

using (var response = await httpClient.PostAsync("ccu/v2/queues/default", content))
{
string responseData = await response.Content.ReadAsStringAsync();
var b = responseData.Replace('"', ' ');
var r = b.Split(',', '\n');
// Response.Write(r[1]);
}
}
}
}
}

You need to use an Akamai signing library. There is a library for C# here:
https://github.com/akamai-open/AkamaiOPEN-edgegrid-C-Sharp
The library's README includes sample code to get started integrating it into your system.
