nop 中创建任务(Task)

Posted 2021-02-18 hpbkin

NopCommerce 中Task 原理是服务端开启线程定时跑。

1.在数据表ScheduleTask中添加一条数据，

 

 2.自定义类，继承ITask 即可

using Data.Log4Net;
using Data.Services.Tasks;
using System;
using System.Net;
using System.Security.Policy;
using System.Web;

namespace Data.Services.Common
{
    /// <summary>
    /// Represents a task for keeping the site alive
    /// </summary>
    public partial class KeepAliveTask : ITask
    {
        //private readonly IStoreContext _storeContext;

        //public KeepAliveTask(IStoreContext storeContext)
        //{
        //    this._storeContext = storeContext;
        //}

        /// <summary>
        /// Executes a task
        /// </summary>
        public void Execute()
        {
            //WriteLog.Info("KeepAliveTask,Execute");
            string domainUrl = System.Configuration.ConfigurationManager.AppSettings["domainUrl"];
            string url = domainUrl + "/keepalive/index";//"http://localhost:8060/keepalive/index";
            WriteLog.Info("KeepAliveTask,url=" + url);
            using (var wc = new WebClient())
            {
                var down = wc.DownloadString(url);
                WriteLog.Info("KeepAliveTask,down=" + down);
            }
        }
    }
}

OK，服务端会每隔60秒 跑 Execute()方法。
