我正在尝试在使用WebForms创建的项目中实现IHTTPCLIENTFACTORY，.NET FREMERWORK 4.7.2：

global.asax：

 公共静态iserviceProvider ServiceProvider;

  void application_start（对象发送者，EventArgs e）
  {
      var容器= this.addunity（）;
      container.RegisterType＆lt; ihttpClientFactoryProvider，httpclientFactoryProvider＆gt;（）;
      container.RegisterType＆lt; imyanager，mymanager＆gt;（）;

      var hostbuilder = new hostbuilder（）;
      hostbuilder.configureservices（configureservices）;
      var host = hostbuilder.build（）;

      ServiceProvider = host.Services;

      //在应用程序启动上运行的代码
      RouteConfig.RegisterRoutes（Routetable.Routes）;
      Bundleconfig.RegisterBundles（Bondletable.Bundles）;
  }

  void configureservices（iservCollection Services）
  {
      services.addhttpclient（）;
  }

呼叫ihttpclientFactory的类：

 公共类HTTPCLIENTFACTORYPROVIDER：IHTTPCLIENTFACTORYPROVIDER
  {
  私有ReadOnly IHTTPClientFactory _httpClientFactory;

  公共HTTPCLIENTFACTORYPROVIDER（IHTTPCLIENTFACTORY HTTPCLIENTFACTORY）
  {
      _httpClientFactory = httpClientFactory;
  }

  公共字符串getData（）
  {
      var test = _httpClientFactory.CreateClient（）;

      返回 ””;
  }
  }

mymanager注入httpclientfactoryprovider：

 公共类Mymanager：Imyanager
   {
    私有Readonly IHTTPCLIENTFACTORYPROVIDER _httpClientFactoryProvider;

    公共Mymanager（IHTTPCLIENTFACTORYPROVIDER HTTPCLIENTFACTORYPROVIDER）
   {
      _httpClientFactoryProvider = httpClientFactoryProvider;
   }

   公共字符串getData（）
   {
      返回_httpClientFactoryProvider.getData（）;
   }
 }

page default.aspx：

 公共部分类_DEFAULT：页面
  {
   私人读书imyanager _mymanager;

   public _default（Imyanager Mymanager）
   {
      _mymanager = mymanager;
   }

   public _default（）
   {

   }

   受保护的void page_load（对象发送者，EventArgs e）
   {
      如果（！iSpostback）
      {
          var结果= _mymanager.getData（）;
      }
  }
}

问题是_mymanager始终是空的，我做了所有可能的解决方案，但什么也没有。

I'm trying to implement IHttpClientFactory in my project created with webforms, .NET Framework 4.7.2 :

Global.asax :

  public static IServiceProvider ServiceProvider;

  void Application_Start(object sender, EventArgs e)
  {
      var container = this.AddUnity();
      container.RegisterType<IHttpClientFactoryProvider, HttpClientFactoryProvider>();
      container.RegisterType<IMyanager, MyManager>();

      var hostBuilder = new HostBuilder();
      hostBuilder.ConfigureServices(ConfigureServices);
      var host = hostBuilder.Build();

      ServiceProvider = host.Services;

      // Code that runs on application startup
      RouteConfig.RegisterRoutes(RouteTable.Routes);
      BundleConfig.RegisterBundles(BundleTable.Bundles);
  }

  void ConfigureServices(IServiceCollection services)
  {
      services.AddHttpClient();
  }

The class that call IHttpClientFactory:

  public class HttpClientFactoryProvider : IHttpClientFactoryProvider
  {
  private readonly IHttpClientFactory _httpClientFactory;

  public HttpClientFactoryProvider(IHttpClientFactory httpClientFactory)
  {
      _httpClientFactory = httpClientFactory;
  }

  public string GetData()
  {
      var test = _httpClientFactory.CreateClient();

      return "";
  }
  }

MyManager that inject HttpClientFactoryProvider :

  public class MyManager : IMyanager
   {
    private readonly IHttpClientFactoryProvider _httpClientFactoryProvider;

    public MyManager(IHttpClientFactoryProvider httpClientFactoryProvider)
   {
      _httpClientFactoryProvider = httpClientFactoryProvider;
   }

   public string GetData()
   {
      return _httpClientFactoryProvider.GetData();
   }
 }

Page Default.aspx:

  public partial class _Default : Page
  {
   private readonly IMyanager _mymanager;

   public _Default(IMyanager mymanager)
   {
      _mymanager = mymanager;
   }

   public _Default()
   {

   }

   protected void Page_Load(object sender, EventArgs e)
   {
      if (!IsPostBack)
      {
          var result = _mymanager.GetData();
      }
  }
}

The problem is that _mymanager is always null, i have done all possible solutions but nothing.
