javascript - 运行状况检查网址无效:无法匹配任何路由

我正在开发.net Core 2.2 / Angular 8应用程序。
我听说过HealthCheck，并且想在我的应用程序中实现它。
 这是我的Startup.cs：

    using HealthChecks.UI.Client;
    using Microsoft.AspNetCore.Builder;
    using Microsoft.AspNetCore.Diagnostics.HealthChecks;
    using Microsoft.AspNetCore.Hosting;
    using Microsoft.AspNetCore.Http.Features;
    using Microsoft.AspNetCore.Mvc;
    using Microsoft.AspNetCore.SpaServices.AngularCli;
    using Microsoft.Extensions.Configuration;
    using Microsoft.Extensions.DependencyInjection;

    namespace OnlineXmlTools
    {
        public class Startup
        {
            public Startup(IConfiguration configuration)
            {
                Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {

        services.AddSwaggerDocument();
        services.AddSession();
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

        services.Configure<FormOptions>(x =>
        {
            x.ValueLengthLimit = int.MaxValue;
            x.MultipartBodyLengthLimit = int.MaxValue; // In case of multipart
        });
        // In production, the Angular files will be served from this directory
        services.AddSpaStaticFiles(configuration =>
        {
            configuration.RootPath = "ClientApp/dist";
        });
        services.AddHttpContextAccessor();

        services.AddAntiforgery(options =>
        {
            // Set Cookie properties using CookieBuilder properties†.
            options.FormFieldName = "AntiforgeryFieldname";
            options.HeaderName = "X-CSRF-TOKEN-HEADERNAME";
            options.SuppressXFrameOptionsHeader = false;
        });
        services.AddHealthChecks();
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        // Register the Swagger generator and the Swagger UI middlewares
        app.UseOpenApi();
        app.UseSwaggerUi3();
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Error");
            app.UseHsts();
        }

        app.UseHttpsRedirection();
        app.UseStaticFiles();
        app.UseSpaStaticFiles();

        app.UseSession();
        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller}/{action=Index}/{id?}");
        });

        app.UseSpa(spa =>
        {
            // To learn more about options for serving an Angular SPA from ASP.NET Core,
            // see https://go.microsoft.com/fwlink/?linkid=864501

            spa.Options.SourcePath = "ClientApp";

            if (env.IsDevelopment())
            {
                spa.UseAngularCliServer(npmScript: "start");
            }
        });
        app.UseHealthChecks("/healthcheck", new HealthCheckOptions
        {
            Predicate = _ => true,
            ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse
        });
    }
}

}

启动我的应用程序（https://localhost:44328/）时，我尝试按照中间件中的说明访问运行状况检查URL：
        https://localhost:44328/healthcheck
它应该显示信息。
相反，我有此错误：
        错误错误：未捕获（承诺）：错误：无法匹配任何路由。网址段：“运行状况检查”

我错过了什么 ？
谢谢

最佳答案

您的管道订单不正确，应该是这样

        app.UseHealthChecks("/healthcheck");

        app.UseSpa(spa =>
        {
            // To learn more about options for serving an Angular SPA from ASP.NET Core,
            // see https://go.microsoft.com/fwlink/?linkid=864501

            spa.Options.SourcePath = "ClientApp";

            if (env.IsDevelopment())
            {
                spa.UseAngularCliServer(npmScript: "start");
            }
        });
