.NET核心3API-在一次请求后停止工作？

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // 其他配置

    app.UseShutdownMiddleware();

    // 其他中间件配置
}

public void ConfigureServices(IServiceCollection services)
{
    // 其他服务注册

    services.AddSingleton<IHostApplicationLifetime, HostApplicationLifetime>();

    // 其他服务注册
}

public class HostApplicationLifetime : IHostApplicationLifetime
{
    private readonly ILogger<HostApplicationLifetime> _logger;
    private readonly IApplicationLifetime _applicationLifetime;

    public HostApplicationLifetime(ILogger<HostApplicationLifetime> logger, IApplicationLifetime applicationLifetime)
    {
        _logger = logger;
        _applicationLifetime = applicationLifetime;
        _applicationLifetime.ApplicationStopping.Register(OnStopping);
    }

    public void OnStopping()
    {
        // 执行停止应用程序的操作
        _logger.LogInformation("Application is stopping...");
    }

    // 实现其他IHostApplicationLifetime接口成员
    // ...
