Healtcheck url 不起作用:无法匹配任何路由

Question

我正在开发一个.net Core 2.2/Angular 8应用程序。 我听说过运行状况检查，我想在我的应用程序中实现它。 这是我的创业.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
});
}
}

}

当我启动应用程序 (https://localhost:44328/( 时，我尝试访问中间件中所述的运行状况检查 URL： https://localhost:44328/healthcheck 它应该显示信息。 相反，我有这个错误： 错误 错误：未捕获(在承诺中(：错误：无法匹配任何路由。网址细分："运行状况检查">

我错过了什么吗？ 谢谢

你的管道顺序不正确，应该是这样的

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");
}
});
