httpclient - dotnet 5 如何在 HttpClient 中使用 Windows 身份验证凭据

Question

.net 5 中没有发生在 .net core 3.1 中的问题 Windows 身份验证未传递给 HttpClient

在 .net core 3.1 上工作的相同代码：

[HttpGet("getuser")]
public async Task<ActionResult> GetUser()
{
   var handle = new HttpClientHandler
   {
     Credentials = CredentialCache.DefaultCredentials,
     //UseDefaultCredentials = true, //=> try this too
     AllowAutoRedirect = true,
    };
    var httpclient = new HttpClient(handle);
    var res = await httpclient.GetAsync("http://service/rest/getcurrentuser"); //get 401
    var result = await res.Content.ReadAsStringAsync();
    return Ok(result);
  }
