DNN Schedule

1. 创建一个class library项目 (把xxx替换成你自己的实际名字)

Demo code:

Code
using System;
using System.Collections.Generic;
using System.Text;
using DotNetNuke.Services.Scheduling;
using DotNetNuke.Services.Exceptions;
using System.Net;
using System.IO;


namespace Com.xxx.KeepAlive
{
    public class KeepAlive : SchedulerClient
    {
        //REQUIRED
        public KeepAlive(ScheduleHistoryItem objScheduleHistoryItem)
        {
            this.ScheduleHistoryItem = objScheduleHistoryItem;
        }

        public override void DoWork()
        {
            HttpWebResponse webRes = null;
            Stream objStream = null;
            StreamReader objStreamReader = null;

            try
            {
                webRes = (HttpWebResponse)WebRequest.Create("http://www.xxx.cn/KeepAlive.aspx").GetResponse();
                objStream = webRes.GetResponseStream();
                objStreamReader = new StreamReader(objStream, Encoding.Default);
                string content = objStreamReader.ReadToEnd();

                //Optional
                base.ScheduleHistoryItem.AddLogNote(content + " -- " + DateTime.Now);
                
                //objStreamReader.Close();
                //objStream.Close();
                //webRes.Close();

                //REQUIRED
                base.ScheduleHistoryItem.Succeeded = true;
            }
            catch (Exception exce)
            {
                //REQUIRED
                base.ScheduleHistoryItem.Succeeded = false;
                base.Errored(ref exce);

                //Optional
                DotNetNuke.Services.Exceptions.Exceptions.LogException(exce);
            }
            finally
            {
                if (objStreamReader != null)
                {
                    objStreamReader.Close();
                }

                if (objStream != null)
                {
                    objStream.Close();
                }

                if (webRes != null) { webRes.Close(); }
            }
        }
    }
}

之后，编译成dll，并放到dnn的bin目录下

2. DNN里面的Schedule配置。

用host用户登陆后，到Host->Schedule里面，点击“Add new item to Schedule”

如下图：

需要注意的就是：Full class Name and Assembly。

比如本例的Full class Name 就是：Com.xxx.KeepAlive.KeepAlive,

Assembly的Name就是Com.xxx.KeepAlive (这个名字是我自己取的，你可以在项目-》右键属性中修改和查看。)

ok,my story is over.
