使用FluentScheduler-ASP.NET Core MVC [英] Using FluentScheduler - ASP.NET Core MVC

问题描述

我目前使用ASP.NET Core MVC(.NET 4.6.1)进行了简单的网站设置，并且我希望定期进行一些操作，例如每天结束时自动向注册会员发送电子邮件.

I currently have a simple website setup with ASP.NET Core MVC (.NET 4.6.1), and I would like to periodically do some processes like automatically send emails at the end of every day to the registered members.

进行搜索后，我遇到了两个常见的解决方案-Quartz.NET和FluentScheduler.

After doing some searching, I came across two common solutions - Quartz.NET and FluentScheduler.

基于此 SO线程，我发现了使用FluentScheduler的方法更易于消化和用于我的简单任务.在将以下代码行快速实现到Program.cs类中之后，我每分钟都会成功发送一封电子邮件(出于测试目的).

Based on this SO thread, I found the approach of using FluentScheduler more easier to digest and use for my simple task. After quickly implementing the following lines of code into my Program.cs class, I had the emails going out successfully every minute (for testing purposes).

public class Program
{
    public static void Main(string[] args)
    {
        var host = new WebHostBuilder()
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseIISIntegration()
            .UseStartup<Startup>()
            .Build();

            var registry = new Registry();
            JobManager.Initialize(registry);

            JobManager.AddJob(() => MyEmailService.SendEmail(), s => s
                  .ToRunEvery(1)
                  .Minutes());

            host.Run();

    }
}

但是，除了发送电子邮件之外，我还需要进行一些后端处理，例如发送邮件时，更新数据库中的用户记录.为此，我通常将实体框架上下文注入到控制器的构造函数中，并使用它来获取/更新SQL记录.

However, now apart from sending emails I also need to do some back-end processing for e.g. updating the user records in the DB when mails are being sent out. For this, I normally inject my Entity Framework Context into the constructor of my controllers and use it to get/update SQL records.

我的问题是，由于我无法真正将这些服务注入main方法中，因此初始化注册表和添加作业以进行调度的合适位置在哪里?

My question is, since I cannot really inject these services into the main method, where would be the appropriate place to initialize the registry and add jobs for scheduling?

感谢您的帮助，我对此有些陌生，因此非常感谢您提供一些指导！

Thanks for the help, I am a little new to this so a little guidance would be much appreciated!

推荐答案

不是在程序的Main函数中，而是在Startup.cs中在app.UseMvc ...

Instead of Program's Main function, I initialized the same in Startup.cs before app.UseMvc..

public void Configure(...., IDependencyObject dependencyObject)
{
           ....
           JobManager.Initialize(new MyRegistry(dependencyObject));

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "api/{controller}/{action}/{id?}");
            });
}

我的注册表类如下:

public class MyRegistry: Registry
{
    public MyRegistry(IDependencyObject dependencyObject)
    {            
        Schedule(() => new SyncUpJob(dependencyObject)).ToRunNow().AndEvery(10).Seconds();
    }
}

我的Job类如下:

public class SyncUpJob: IJob
{
    public SyncUpJob(IDependencyObject dependencyObject)
    {
        DependencyObject= dependencyObject;
    }

    public IDependencyObject DependencyObject{ get; set; }

    public void Execute()
    {
        // call the method to run weekly here
    }
}
