개발환경 C# winforms 입니다.
1.웹뷰로 해서 https://kauth.kakao.com/oauth/authorize로 code는 가져왓습니다.
2.그런다음 api로 https://kauth.kakao.com를 호출하였습니다.
var client = new RestClient("https://kauth.kakao.com");
var request = new RestRequest("oauth/token/", Method.POST);
request.AddParameter("grant_type", "authorization_code");
request.AddParameter("client_id", "----");
request.AddParameter("redirect_uri", "http://localhost/oauth");
request.AddParameter("code", code);
request.AddHeader("Content-type", "application/x-www-form-urlencoded");
request.AddHeader("charset", "utf-8");
request.AddHeader("Connection", "Keep-Alive");
request.AddHeader("User-Agent", "RestSharp");
IRestResponse response = client.Execute(request);
var content = response.Content;
Console.WriteLine(content);
"{\"status\":-500,\"message\":\"An unexpected error has occurred. The error may have been caused by temporary errors in the server or in the network connection. The Kakao Team is working to solve the problem.\"}"
아래는 curl 호출 결과 입니다.

3.restsharp이라는 라이브러리를 사용중입니다.
라이브러리에서 https 문제인것 같아서 https://jsonplaceholder.typicode.com/를 호출해봤습니다.
var client = new RestClient("https://jsonplaceholder.typicode.com/");
var request = new RestRequest("users/", Method.POST);
request.AddParameter("name", "value");
IRestResponse response = client.Execute(request);
var content = response.Content; // raw content as string
Console.WriteLine(content);
위의 결과는 아래와 같습니다. 정상적으로 https 통신이 이뤄집니다.
"{\n \"name\": \"value\",\n \"id\": 11\n}"
