ASP.NET 健康检查不适用于 Blazor 应用程序部署

Question

我有一个 ui Blazor 服务器应用程序并将其部署在 IIS 上。除了健康检查之外，它的所有核心功能都符合预期运行ning。当我通过 visual studio 运行 Blazor 应用程序时，我在 healthcheck-ui 中得到以下结果：

但是，当我转到已部署应用程序的健康检查 ui 页面时，我看到的是：

如您所见，状态是不健康的，sql 健康检查有 'disappeared' 而端点健康检查似乎有不同的名称？下面是我的 Startup.cs:

using AjuaBlazorServerApp.HealthChecks;
using HealthChecks.UI.Client;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Diagnostics.HealthChecks;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Diagnostics.HealthChecks;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;

namespace AjuaBlazorServerApp
{
    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.
        // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddRazorPages();
            services.AddServerSideBlazor();
            services.AddHostedService<PeriodicExecutor>();
            services.AddHealthChecks()
            .AddCheck<AjuaEndpointHealth>("AjuaEndpoint",null) 
            .AddSqlServer(Configuration["sqlString"],
                healthQuery: "select 1",
                failureStatus: HealthStatus.Degraded,
                name: "SQL Server");
            services.AddHealthChecksUI(opt =>
            {
                opt.SetEvaluationTimeInSeconds(5); //time in seconds between check    
                opt.MaximumHistoryEntriesPerEndpoint(60); //maximum history of checks    
                opt.SetApiMaxActiveRequests(1); //api requests concurrency    
                opt.AddHealthCheckEndpoint("Ajua API", "/health"); //map health check api    
            }).AddInMemoryStorage();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory)
        {
            loggerFactory.AddLog4Net("log4net.config");
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Error");
            }

            app.UseStaticFiles();

            app.UseRouting();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapBlazorHub();
                endpoints.MapFallbackToPage("/_Host");
                endpoints.MapHealthChecks("/health", new HealthCheckOptions()
                {
                    Predicate = _ => true,
                    ResponseWriter = UIResponseWriter.
                    WriteHealthCheckUIResponse
                });
                endpoints.MapHealthChecksUI();
            });
        }
    }
}

如果我们采用托管应用程序的以下示例 IP 1.1.1.1:80 是否有一些我应该在 Startup.cs 或任何地方设置的设置否则为了解决这个问题？

Answer 1

我找到了解决方案。基本上在 AddHealthCheckEndpoint 覆盖中添加 /health 前面的主机 ip 和端口。请记住 http 和 https 不可互换，因此请根据您在 IIS 中的配置使用正确的。

            services.AddHealthChecksUI(opt =>
            {
                opt.SetEvaluationTimeInSeconds(5); //time in seconds between check    
                opt.MaximumHistoryEntriesPerEndpoint(60); //maximum history of checks    
                opt.SetApiMaxActiveRequests(1); //api requests concurrency    
                opt.AddHealthCheckEndpoint("Ajua API", "http://1.1.1.1:80/health"); //map health check api    
            }).AddInMemoryStorage();
