返回ASP.NET Core应用程序根目录的特定响应

Question

我创建了一个ASP.NET Core应用程序，其中一些控制器工作正常。

路由系统的结构类似于https://something.com/api/controller。

但是，我使用的是在Azure中始终选择选项以保持Web应用程序始终处于活动状态并且不会在空闲时暂停。

问题是，每次5分钟，天青坪我的应用程序的地址https://something.com和回来了这是在我的应用分析报表，记录一个404错误。

我想知道如何处理对我的应用程序根目录的请求，并返回200 HTTP结果。

这里是我的启动类：

public class Startup 
{ 
    public Startup(IHostingEnvironment env) 
    { 
     var builder = new ConfigurationBuilder() 
      .SetBasePath(env.ContentRootPath) 
      .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true) 
      .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true) 
      .AddEnvironmentVariables(); 
     Configuration = builder.Build(); 
    } 

    private IConfigurationRoot Configuration { get; } 

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

     services.AddSingleton<ICachingService>(e => new CachingService(Configuration["Redis:ConnectionString"])); 

     var loggingService = new LoggingService(Configuration["ApplicationInsights:InstrumentationKey"]); 
     services.AddSingleton(typeof(ILoggingService), loggingService); 
    } 

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. 
    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) 
    { 
     loggerFactory.AddConsole(Configuration.GetSection("Logging")); 
     loggerFactory.AddDebug(); 

     app.UseMvc(); 
    } 
}

好吧，其实它是出奇的简单：

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) 
    { 
     app.UseMvc(); 
     app.Run(async context => 
     { 
      await context.Response.WriteAsync("API"); // returns a 200 with "API" as content. 
     }); 
    }
