✅ Moving from HttpWebRequest to HttpClient

Hello, I'm in need of help refactoring from HttpWebRequest(obsolete) to HttpClient. I've tried to do it for hours but can't get it to work. Could someone please help me out? Here's my currently obsolete code

var request = (HttpWebRequest)WebRequest.Create("https://127.0.0.1:" + port + url);

                request.PreAuthenticate = true;
request.ContentType = "application/json";
request.Method = type;          request.Headers.Add("Authorization", "Basic " + token);

var httpResponse =(HttpWebResponse)request.GetResponse();

using (var
 streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
return streamReader.ReadToEnd();
}

var request = (HttpWebRequest)WebRequest.Create("https://127.0.0.1:" + port + url);

                request.PreAuthenticate = true;
request.ContentType = "application/json";
request.Method = type;          request.Headers.Add("Authorization", "Basic " + token);

var httpResponse =(HttpWebResponse)request.GetResponse();

using (var
 streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
return streamReader.ReadToEnd();
}

Two things to note: >HttpClient methods are asynchronous >You need to define a client first

async Task MakeTestGetRequest(){
  //Create Client, this can be reused if you want it too
  HttpClient client = new HttpClient();

  //Create the Request
  using (var requestMessage = HttpRequestMessage(HttpMethod.Get, "https://your.site.com"))
  {
    requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", your_token);
    await httpClient.GetAsync(requestMessage);
  }
}

async Task MakeTestGetRequest(){
  //Create Client, this can be reused if you want it too
  HttpClient client = new HttpClient();

  //Create the Request
  using (var requestMessage = HttpRequestMessage(HttpMethod.Get, "https://your.site.com"))
  {
    requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", your_token);
    await httpClient.GetAsync(requestMessage);
  }
}

MSDN: https://learn.microsoft.com/en-us/dotnet/api/system.net.http.httpclient?view=net-7.0

HttpClient Class (System.Net.Http)

Provides a class for sending HTTP requests and receiving HTTP responses from a resource identified by a URI.

Also, since you seem to have a generic method for requests, I think you might need multiple methods for different Requests (GET, POST, PATCH, etc) I don't think there is a way to generalize it

You can also see this stackoverflow answer, as a good example of an HttpClient request: https://stackoverflow.com/questions/10679214/how-do-you-set-the-content-type-header-for-an-httpclient-request

Stack Overflow

How do you set the Content-Type header for an HttpClient request?

I'm trying to set the Content-Type header of an HttpClient object as required by an API I am calling. I tried setting the Content-Type like below: using (var httpClient = new HttpClient()) {
