为什么不在blazor webassembly中发送承载令牌?

我正在尝试配置我的http客户端以发送jwt令牌

使用此代码

public class HttpClientWithToken
    {
        public HttpClientWithToken(HttpClient httpClient)
        {
            HttpClient = httpClient;
        }

        public HttpClient HttpClient { get; }
    }

public static async Task Main(string[] args)
            {
                var builder = WebAssemblyHostBuilder.CreateDefault(args);
                builder.RootComponents.Add<App>("#app");
    
                builder.Services.AddHttpClient<HttpClientWithToken>(
                     client => client.BaseAddress = new Uri(builder.HostEnvironment.BaseAddress))
                     .AddHttpMessageHandler<BaseAddressAuthorizationMessageHandler>();
    
                ConfigureServices(builder.Services);
    
                var host = builder.Build();

                await host.RunAsync();
            }

我得到错误:“没有注册类型为“microsoft.aspnetcore.components.webassembly.authentication.baseaddressauthorizationmessagehandler”的服务”

使用此代码

public static async Task Main(string[] args)
        {
            var builder = WebAssemblyHostBuilder.CreateDefault(args);
            builder.RootComponents.Add<App>("#app");

            builder.Services.AddSingleton<BaseAddressAuthorizationMessageHandler>();

            builder.Services.AddHttpClient<HttpClientWithToken>(
                 client => client.BaseAddress = new Uri(builder.HostEnvironment.BaseAddress))
                 .AddHttpMessageHandler<BaseAddressAuthorizationMessageHandler>();

            ConfigureServices(builder.Services);

            var host = builder.Build();

            await host.RunAsync();
        }

我收到错误:“在尝试激活“Microsoft.AspNetCore.Components.WebAssembly.Authentication.IAccessTokenProvider”时,无法解析类型为“Microsoft.Asp NetCore.Components.WebAssembly.Authentication.BaseAddressAuthorizationMessageHandler”的服务。”

我错过了什么? 基于我下面的示例,第一个代码应该在头中发送承载。

我可以调用我的api,并在设置HttpClient时获得承载令牌。DefaultRequestHeaders。授权,但我无法使用配置获取令牌。
