ASP .NET Core 3.1 Windows Auth用户模拟来调用WebAPI

如何解决ASP .NET Core 3.1 Windows Auth用户模拟来调用WebAPI

我有一个使用Windows身份验证的.net core 3.1 Web应用程序。该Web应用程序需要以用户身份向.net Core 3.1 API发出请求，并且该API还需要以用户身份调用其他内部网服务。该应用程序和API托管在同一服务器上，并且都使用Windows身份验证。

模拟当前Windows身份验证用户发出API请求的正确方法是什么？（应用程序可以成功进行对API的调用而无需模拟，但是该请求将作为应用程序运行HomeController中的这两种测试方法是从搜寻MS文档和SO示例的几天中拼凑而成的，但是每种方法为版本FileLoadException生成了System.Net.Http，而该版本并未被引用。 csproj文件-仅在使用模拟时才会发生。

// impersonation in the method
public async Task<IActionResult> AskForSomethingWithImpersonationAsync()
{
    var apiBase = new Uri(configuration["Api"]);
    var response = string.Empty;
    var user = (WindowsIdentity)HttpContext.User.Identity;

    await WindowsIdentity.RunImpersonated(user.AccessToken,async () =>
    {
        var credentialsCache = new CredentialCache { { apiBase,"NTLM",CredentialCache.DefaultNetworkCredentials } };
        var handler = new HttpClientHandler() { Credentials = credentialsCache };
        var httpClient = new HttpClient(handler) { BaseAddress = apiBase,Timeout = new TimeSpan(0,10) };
        httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

        response = httpClient.GetStringAsync("/api/v2/log").Result;
    });

    return Content(response);
}

// impersonation middleware
[ServiceFilter(typeof(ImpersonationFilter))]
public async Task<IActionResult> AskForSomethingFilteredAsync()
{
    var apiBase = new Uri(configuration["Api"]);
    var response = string.Empty;
    var user = (WindowsIdentity)HttpContext.User.Identity;

    var credentialsCache = new CredentialCache { { apiBase,CredentialCache.DefaultNetworkCredentials } };
    var handler = new HttpClientHandler() { Credentials = credentialsCache };
    var httpClient = new HttpClient(handler) { BaseAddress = apiBase,10) };
    httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    response = await httpClient.GetStringAsync("/api/v2/log");

    return Content(response);
}

以下是模拟过滤器中间件：

using Microsoft.AspNetCore.Mvc.Filters;
using System.Security.Principal;
using System.Threading.Tasks;

namespace HBACaller.ActionFilter
{
    public class ImpersonationFilter : IAsyncActionFilter
    {
        public async Task OnActionExecutionAsync(
            ActionExecutingContext context,ActionExecutionDelegate next)
        {
            var user = (WindowsIdentity)context.HttpContext.User.Identity;

            await WindowsIdentity.RunImpersonated(user.AccessToken,async () =>
            {
                await next();
            });
        }
    }
}

这是我在网络浏览器的“网络响应”标签中看到的错误：

System.IO.FileLoadException: 
File name: 'System.Net.Http,Version=4.2.2.0,Culture=neutral,PublicKeyToken=b03f5f7f11d50a3a

据我所知，该版本未在任何地方引用。 .csproj具有以下功能：

<ItemGroup>
  <PackageReference Include="System.Net.Http" Version="4.3.4" />
  <PackageReference Include="System.Security.Principal" Version="4.3.0" />
</ItemGroup>

当此代码发布到测试IIS服务器而不是通过Visual Studio在本地运行时，在异常结束时会附加一条消息： Either a required impersonation level was not provided,or the provided impersonation level is invalid.
