RestSharp 到 HttpClient

Question

var client = new RestClient("http://10.0.0.244:8885/terminal/info");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddHeader("apikey", "adasdsadasd");
var body = @"{}";
request.AddParameter("application/json", body,  ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);

Could someone, please, help me write this code with HttpClient? I try following code.

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri("http://10.0.0.244:8885/");
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Clear();
    HttpRequestMessage request = new HttpRequestMessage();
    request.Method = HttpMethod.Post;
    request.RequestUri = new Uri($"{client.BaseAddress}/terminal/info");
    request.Headers.Add("apikey", "adasdsadasd");
    var body = Newtonsoft.Json.JsonConvert.SerializeObject(new { });
    request.Content = new StringContent(body, Encoding.UTF8, "application/json");//CONTENT-TYPE header
    request.Content.Headers.Clear();
    request.Content.Headers.ContentLength = 2;
    request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    HttpResponseMessage response = client.SendAsync(request).GetAwaiter().GetResult();
    var x = response.Content.ReadAsStringAsync().GetAwaiter().GetResult();

}

But it response with Status Code 400 (ParseError)

You can accomplish what you are trying to do with much less code. Also this should be in an async method. Below is an example

internal async Task<string> GetResponse()
{
    using var client = new HttpClient();
    client.BaseAddress = new Uri("http://10.0.0.244:8885/");
    client.DefaultRequestHeaders.Clear();
    client.DefaultRequestHeaders.Add("apikey", "adasdsadasd");
    var content = new StringContent("{}", Encoding.UTF8, "text/plain");
    var response = await client.PostAsync("/terminal/info", content);
    if (response.IsSuccessStatusCode)
    {
        return await response.Content.ReadAsStringAsync();
    }
    return null;
}
