ASP.net Web API Core

Question

Hello everyone,

 

Need help in web api post request.

 

For below code i am getting 401 unauthorized error. But it works with POSTMAN. Can someone help me why is it failing via code. Below is a POST method.

 

using (StreamReader sr = new StreamReader(json))

{

string json = sr.ReadToEnd().Trim();

var request = (HttpWebRequest)WebRequest.Create("url");

var data = Encoding.ASCII.GetBytes(json);

request.ContentType= "application/json";

request.ContentLength=data.Length;

request.Headers.Add("RequestToken", XXX);

request.Headers.Add("Key", XXX);

request.Headers.Add("Client", XXX);

request.Headers.Add("TimeStamp", XXX);

request.Method = "POST";

using (var stream = request.GetRequestStream())

{

stream.Write(data, 0, data.Length);

}

var response = (HttpWebResponse)request.GetResponse();// at this stage I am getting "'The remote server returned an error: (401) Unauthorized.'"

var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

}
