  Hi abfrank,

  • You need to add Microsoft.Extensions.Http and Microsoft.Extensions.DependencyInjection through NuGet.
  • Please refer to the following examples for specific usage.

  using Microsoft.Extensions.DependencyInjection;

          public async Task<string> GetAsync()
          {
  
              var serviceProvider = new ServiceCollection().AddHttpClient().BuildServiceProvider();
              var httpClientFactory = serviceProvider.GetService<IHttpClientFactory>();
              var client = httpClientFactory.CreateClient();
              var response = await client.SendAsync(new HttpRequestMessage(HttpMethod.Get, "https://localhost:44346/api/values/get?id=1"));
              var content = await response.Content.ReadAsStringAsync();
              return content;
          }
          public string Get(int id)
          {
              return "value";
          }

  Here is the result.

  instead of that old code, I'd use a JWT token as the payload instead. It well understood, and there are lots of libraries to encode and decode. They are just for bearer tokens

  Hi abfrank,

  • According to the link you provided, I tested the code and found that "HttpClientFactory.Create" can be used. You can check whether you have quoted "using System.Net.Http;". The following is an example of my test, please refer to it.
  • You can get the code of CustomDelegatingHandler from the link you gave.

          public async Task<string> GetAsync()
          {
              //string apiBaseAddress = "https://localhost:44346/api/values/get?id=1";
              string apiBaseAddress = "https://localhost:44346/";
              CustomDelegatingHandler customDelegatingHandler = new CustomDelegatingHandler();
              var test = new Test23 { Content= "Test"};
              HttpClient client = HttpClientFactory.Create(customDelegatingHandler);
              HttpResponseMessage response = await client.PostAsJsonAsync(apiBaseAddress + "api/values/Post", test);
              //HttpResponseMessage response = await client.GetAsync(apiBaseAddress);
              string content = "";
              if (response.IsSuccessStatusCode)
              {
                  content = await response.Content.ReadAsStringAsync();
              }
              return content;
          }
          public IHttpActionResult Post(Test23 test)
          {
              return Ok("success");
          }

  Here is the result.
