Question

我目前正在开发一个处理约会和重复活动的Web API。我发现quartz-scheduler.net是合适的，但问题是它与asp.NET Core版本不兼容。

有没有办法将quartz.NET实现到asp.NET核心，还是有某种替代或替代？

Answer 1

Quartz.NET 3.0 Alpha 1发布：支持.NET Core / netstandard 1.3。请参阅此announcement。

您可以监控此故障单中的进度：Support for .NET Core or vNext #355

我设法按照以下步骤进行：

创建.NET核心服务扩展（QuartzExtension.cs）：

public static class QuartzExtensions
{
    public static void UseQuartz(this IApplicationBuilder app)
    {
        app.ApplicationServices.GetService<IScheduler>();
    }

    public static async void AddQuartz(this IServiceCollection services)
    {
        var properties = new NameValueCollection
        {
            // json serialization is the one supported under .NET Core (binary isn't)
            ["quartz.serializer.type"] = "json",

            // the following setup of job store is just for example and it didn't change from v2
            ["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz",
            ["quartz.jobStore.useProperties"] = "false",
            ["quartz.jobStore.dataSource"] = "default",
            ["quartz.jobStore.tablePrefix"] = "QRTZ_",
            ["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.SqlServerDelegate, Quartz",
            ["quartz.dataSource.default.provider"] = "SqlServer-41", // SqlServer-41 is the new provider for .NET Core
            ["quartz.dataSource.default.connectionString"] = @"Server=(localdb)\MSSQLLocalDB;Database=sta-scheduler-quartz;Integrated Security=true"
        };

        var schedulerFactory = new StdSchedulerFactory(properties);
        var scheduler = schedulerFactory.GetScheduler().Result;
        scheduler.Start().Wait();

        services.AddSingleton<IScheduler>(scheduler);
    }
}

在Startup.cs中使用它如下

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.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();

        // Authentication service
        JwtAuthentication.AddJwtAuthentication(services);

        services.AddQuartz(); // <======== THIS LINE

        services.AddSingleton<IHttpRequestScheduler, HttpRequestScheduler>();
    }

    // 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,
                          IApplicationLifetime lifetime)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseMvc();

        app.UseAuthentication();

        // Add JWT generation endpoint:
        var options = new TokenProviderOptions
        {
            Audience = "ExampleAudience",
            Issuer = "ExampleIssuer",
            SigningCredentials = new SigningCredentials(JwtAuthentication.SIGNING_KEY, SecurityAlgorithms.HmacSha256),
        };

        app.UseMiddleware<TokenProviderMiddleware>(Options.Create(options));

        app.UseQuartz(); // <======== THIS LINE
    }
}

现在每当我想使用调度程序对象时，我都可以使用DependecyInjection来获取它，就像这个例子一样：

public class HttpRequestScheduler : IHttpRequestScheduler
{
    private IScheduler _scheduler;

    public HttpRequestScheduler(IScheduler scheduler)
    {
        _scheduler = scheduler;
    }

    public void Schedule()
    {
        // Whatever you want to do with the scheduler
        ...
    }
}
