基于Redis实现的延时队列

DelayQueue.Redis

基于Redis实现的延时队列，参考 https://tech.youzan.com/queuing_delay/

使用

安装 Nuget 包

dotnet add package DelayQueue.Redis

定义作业

public class TestJob : Job
{
    public TestJob(TimeSpan delay, string body, string jobid) : base(delay, body)
    {
        JobId = jobid;
    }

    public sealed override string JobId { get; set; }
}


public class TestJobHandler : IRequestHandler<JobMessage<TestJob>, bool>
{
    private readonly ILogger<TestJobHandler> _logger;

    public TestJobHandler(ILogger<TestJobHandler> logger)
    {
        _logger = logger;
    }

    public Task<bool> Handle(JobMessage<TestJob> request, CancellationToken cancellationToken)
    {
        var data = request.Data;

        _logger.LogInformation(
            "TestJobHandler消费;Topic:{Topic},JobId:{JobId},Body:{Body}," +
            $"time:{DateTime.Now:yyyy-MM-dd HH:mm:ss}", request.Topic,
            data.JobId, data.Body);

        return Task.FromResult(true);
    }
}

发布延时作业

 public async Task<IActionResult> PubDelayJob([FromServices] IDelayer<TestJob> delayer)
 {
     var jobid = Guid.NewGuid().ToString();

     var delaySeconds = new Random().Next(1, 10);
     await delayer.PutDelayJob(
         new TestJob(TimeSpan.FromSeconds(delaySeconds), "abcde====" + jobid, jobid));

     return Content($"{jobid},{delaySeconds}s后执行,time:{DateTime.Now:yyyy-MM-dd HH:mm:ss}");
 }

配置

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

    services.AddDelayQueue(Configuration);
    //services.AddDealyQueue(
    //  "127.0.0.1:6379,password=ed4c3f25c68a932fef815,defaultDatabase=1");
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app.ApplicationServices.UseDelayQueue();	

}
