asp.net 访问页面访问统计实现

0x00、背景：

1、用户访问网站所有页面就将访问统计数加1 ，按每月存放。

2、站点并没有用到母版面来实现，所有各个页面都很独立。

3、网站是很早这前的网站，尽量省改动以前的代码。按理说我们应该做一个第三方统计来处理会更好，

但应客户要求还要弄到一个站点下！实际情况是尽量小改页面就好！

0x01、核心代码：

1、实现Http拦截操作，核心代码就是这一个了：

    {

            }

                    var curNode = doc.SelectSingleNode(string.Format("//Visit[@Year=‘{0}‘ and @Month=‘{1}‘]", time.Year, time.Month));
                    if (curNode != null)

                        countAttr.Value = (count + curVisitCount.Count).ToString();
                    }
                    else
                    {
                        //有文件但没有本月数据
                        XmlNode root = doc.SelectSingleNode("Visits");
                        XmlElement element1 = doc.CreateElement("Visit");
                        element1.SetAttribute("Year", time.Year.ToString());
                        element1.SetAttribute("Month", time.Month.ToString());
                        element1.SetAttribute("VCount", curVisitCount.Count.ToString());
                        root.AppendChild(element1);
                    }
                }
                else
                {
                    XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", "utf-8", null);
                    doc.AppendChild(dec);

                    //创建一个根节点（一级）
                    XmlElement root = doc.CreateElement("Visits");
                    doc.AppendChild(root);
                    //创建节点（二级）
                    XmlElement element1 = doc.CreateElement("Visit");
                    element1.SetAttribute("Year", time.Year.ToString());
                    element1.SetAttribute("Month", time.Month.ToString());
                    element1.SetAttribute("VCount", curVisitCount.ToString());
                    root.AppendChild(element1);
                }
                doc.Save(_VisitPath);

                _Cache["VisitCountXml"] = GetVisitCountInXml();
                _Cache["VisitCount"] = _Cache["VisitCountXml"];
                _Cache["CurVisitCount"] = new CurVisitCount { BeginTime = DateTime.Now, Count = 0 };
            }
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            UpdateVisitCount(DateTime.Now);
        }
    }
}

2、web.config中添加配置

<!--
  有关如何配置 ASP.NET 应用程序的详细信息，请访问
  http://go.microsoft.com/fwlink/?LinkId=169433
  -->

<configuration>
  <appSettings>
    ......
    <!--设置更新访问统计Xml,间隔时间（分钟）默认为5分钟-->
    <add key="IntervalMinute" value="5"/>
  </appSettings>
　.......
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
      <add name="customerModule" type="HYSWare.Web.RequestHandler, HYSWare.Web"/>
    </modules>
        ......
  </system.webServer>
</configuration>

3、存放数据的XML文件

<?xml version="1.0" encoding="utf-8"?>
<Visits>
  <Visit Year="2017" Month="8" VCount="92" />
  <Visit Year="2017" Month="7" VCount="13000000" />
</Visits>

4、取得缓存的的访问数据 VisitCountHandler.ashx，VisitCountHandler.ashxcs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace HYSWare.Web
{
    /// <summary>
    /// VisitCountHandler 的摘要说明
    /// </summary>
    public class VisitCountHandler : IHttpHandler
    {
        private static System.Web.Caching.Cache _Cache;

        public VisitCountHandler() {
            if (_Cache == null)
            {
                _Cache = new System.Web.Caching.Cache();
            }
        }

        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
            if (_Cache["VisitCount"] == null)
                _Cache["VisitCount"] = "0";
            context.Response.Write(_Cache["VisitCount"].ToString());
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}

5、调用取访问统计数据的有js代码

var visitCount = 0;
        $.ajax({
            type: "Post",
            url: "VisitCountHandler.ashx",
            data: "{}",
            async: false,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (data) {
                visitCount = data;
            },
            error: function (err) {
                alert(err);
            }
        });

0x02、总结：

主要还是觉得缓存使用感觉有点不对的样子，也许有更好的方法！

还有觉得拦截方法也是挻好用的！
