C#. How to fix error 415 Unsupported Media Type?

Question

C++ / C#

I started writing applications that interact with various APIs. Requests checked in the browser and in the application. GET requests to one of the servers in the application return a 415 Unsupported Media Type error . Other servers don't have this problem. Chrome gets a response.
On advice from google, I tried to add request.ContentType = "application/json" , but there was no result.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
            request.Method = "GET";
            request.ContentType = "application/json";
            
            Stream dataStream;
            HttpWebResponse WebResponse = (HttpWebResponse)request.GetResponse(); //  *(415) Unsupported Media Type.
            dataStream = WebResponse.GetResponseStream();
            StreamReader StreamReader = new StreamReader(dataStream);
            ResponseFromServer = StreamReader.ReadToEnd();
            dataStream.Close();
            WebResponse.Close();
            StatusCode = HttpStatusCode.OK;

Answer 3

What are you betting Content-Typeon in a GET request? This header is set by the side that sends the body - either the server, when sending a response with a body, or the client, when sending a request with a body (ie POST or PUT). As Oleg Pogrebnyak
already pointed out , you need an Accept header .
