ASP.NET Core中的Startup.cs中的Kestrel关闭功能

Question

使用时是否有关机功能Microsoft.AspNet.Server.Kestrel？ASP.NET Core(以前的ASP.NET vNext)显然有一个启动序列,但没有提到关闭序列以及如何处理干净关闭.

Answer 1

在ASP.NET Core中,您可以注册到提供的取消令牌 IApplicationLifetime

public class Startup 
{
    public void Configure(IApplicationBuilder app, IApplicationLifetime applicationLifetime) 
    {
        applicationLifetime.ApplicationStopping.Register(OnShutdown);
    }

    private void OnShutdown()
    {
         // Do your cleanup here
    }
}

IApplicationLifetime还暴露了取消标记ApplicationStopped和ApplicationStarted以及一个StopApplication()方法来停止该应用程序.

Answer 2

除了原始答案,我在尝试连接构造函数中的IApplicationLifetime时遇到错误.

我解决了这个问题:

public class Startup 
{
    public void Configure(IApplicationBuilder app) 
    {
        var applicationLifetime = app.ApplicationServices.GetRequiredService<IApplicationLifetime>();
        applicationLifetime.ApplicationStopping.Register(OnShutdown);
    }

    private void OnShutdown()
    {
         // Do your cleanup here
    }
}
