微信平台自带的统计功能太简单，有时我们需要统计有哪些微信个人用户阅读、分享了微信公众号的手机网页，以及微信个人用户访问手机网页的来源：朋友圈分享访问、好友分享消息访问等。本系统实现了手机网页阅读、分享与来源统计及手机网页在朋友圈的传播路径分析。
本系统使用最传统的三层架构。本文是微统计的第三篇，主要介绍如下内容：
1. 为页面HighCharts画图控件提供数据
2. 接收分享记录信息并保存到数据库
3. 访问记录统计图
4. 阅读统计界面
5. 处理文字请求
前端开发框架使用Bootstrap，没有注明前台的页面表示前台不用显示任何内容
1. 为页面HighCharts画图控件提供数据 Data.aspx
public partial class Data : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string result = "";
string typeStr = System.Web.HttpContext.Current.Request.QueryString["type"];
if (!string.IsNullOrEmpty(typeStr))
{
switch (typeStr)
{
case "navChart": //页面访问图
result = JsonConvert.SerializeObject(GetPageNavStatistics());
break;
case "shareChart": //页面分享图
result = JsonConvert.SerializeObject(GetPageShareStatistics());
break;
}
}
//将HighCharts绘图所需的数据返回给页面
HttpResponse response = System.Web.HttpContext.Current.Response;
response.ContentType = "application/json";
response.Write(result);
response.End();
}
///
/// 获取页面访问统计信息
///
///
private ChartData GetPageNavStatistics()
{
//取过去两天的数据进行统计
DateTime startTime = DateTime.Now.AddDays(-3);
DateTime endTime = DateTime.Now.AddDays(1);
Listtemp = new PageNavBll().GetPageNavList();
List<decimal> statistics = new List<decimal>();
//HighCharts时间轴的起始时间
ChartData chartData = new ChartData
{
StartYear = startTime.Year,
StartDay = startTime.Day,
StartMonth = startTime.Month
};
//生成按小时统计的数据
while (startTime < endTime)
{
statistics.Add(temp.FindAll(e => e.VisitTime >= startTime && e.VisitTime < startTime.AddHours(1)).Count());
startTime = startTime.AddHours(1);
}
chartData.Statistics = statistics.ToArray();
return chartData;
}
///
/// 获取页面分享统计信息
///
///
private ChartData GetPageShareStatistics()
{
//取过去两天的数据进行统计
DateTime startTime = DateTime.Now.AddDays(-3);
DateTime endTime = DateTime.Now.AddDays(1);
Listtemp = new PageShareBll().GetPageShareList();
List<decimal> statistics = new List<decimal>();
//HighCharts时间轴的起始时间
ChartData chartData = new ChartData
{
StartYear = startTime.Year,
StartDay = startTime.Day,
StartMonth = startTime.Month
};
//生成按小时统计的数据
while (startTime < endTime)
{
statistics.Add(temp.FindAll(e => e.ShareTime >= startTime && e.ShareTime < startTime.AddHours(1)).Count());
startTime = startTime.AddHours(1);
}
chartData.Statistics = statistics.ToArray();
return chartData;
}
}
2. 接收分享记录信息并保存到数据库 Share.aspx
public partial class Share : System.Web.UI.Page
{
ILog m_Log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
protected void Page_Load(object sender, EventArgs e)
{
string typeStr = Request.QueryString["type"];
m_Log.Info("share type: " + typeStr);
m_Log.Info("share url: " + Request["url"]);
if (!string.IsNullOrEmpty(typeStr))
{
//识别分享类型
ShareType type = ShareType.Unknown;
switch (typeStr)
{
case "timeline":
type = ShareType.Timeline;
break;
case "friend":
type = ShareType.Friend;
break;
}
//构造分享记录
var pageShare = new PageShareEntity()
{
Id = Guid.NewGuid(),
Url = GetOrigenalUrl(Request["url"]),
ParentShareOpenId = Request["s"],
ShareOpenId = Request["u"],
From = type,
ShareTime = DateTime.Now
};
//保存分享记录
bool insertShare = new PageShareBll().InsertPageShare(pageShare);
m_Log.Info("insert share: " + insertShare.ToString());
}
}
///
/// 获取不含统计相关参数的页面地址
///
/// 网址
/// 不含统计相关参数的页面地址
private string GetOrigenalUrl(string url)
{
url = System.Web.HttpUtility.UrlDecode(url);
Uri uri = new Uri(url);
StringBuilder urlBuilder = new StringBuilder();
//获取不含QueryString的URL
urlBuilder.Append("http://")
.Append(uri.Host)
.Append(uri.AbsolutePath)
.Append("?");
//构造移除统计相关参数的Query
Dictionary<string, string> queryString = uri.Query.Replace("?", "").Split('&').Where(p => !string.IsNullOrEmpty(p)).ToDictionary(p => p.Split('=')[0], p => p.Split('=')[1].Split('#')[0]);
foreach (var key in queryString.Keys)
{
if (key != "s" && key != "u" && key != "from" && key != "code" && key != "state")
{
urlBuilder.Append(key).Append("=").Append(queryString[key]).Append("&");
}
}
return urlBuilder.ToString();
}
}
当发送朋友或朋友圈时保存分享数据。
3. 访问记录统计图 StatisticsPage.aspx
前台：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="StatisticsPage.aspx.cs" Inherits="Statistics.StatisticsPage" %>
"http://www.w3.org/1999/xhtml">
"server">
"Content-Type" content="text/html; charset=utf-8" />
统计
<%-- Bootstrap --%>
"Css/bootstrap.min.css" rel="stylesheet" type="text/css" />
<%-- HighCharts用于图表显示 --%>
"Css/highcharts/charts.css" rel="stylesheet" type="text/css" />
class="container">class="row-fluid">class="span12">访问记录
<%-- 访问记录统计图 --%>class="box">class="box-content">class="row" style="margin-top: 30px; ">class="area">"page-nav-chart"><%-- 访问记录列表 --%>class="maincontentinner1" >"Div12" class="dataTables_wrapper">"page-nav-table" class="table table-bordered responsive dataTable">
<%-- 访问记录列表列名 --%>页面地址 访问来源 访问者openid 分享自openid 访问时间 "page-nav-table-body"><%-- 一行一行生成访问记录列表 --%><% foreach (Statistics.ViewEntity.PageNavEntity entity in (ViewState["NavList"] as List)) { %>class="gradeX odd"> class=" "> <%= entity.From.ToString()%>class=" "> <%= entity.NavOpenId%>class=" "> <%= entity.ShareOpenId%>class=" "> <%= entity.VisitTime.ToString()%><% } %>
用HighCharts来图表显示数据。
后台：
protected void Page_Load(object sender, EventArgs e)
{
//传递给页面显示的记录列表
ViewState["NavList"] = new PageNavBll().GetPageNavList();
ViewState["ShareList"] = new PageShareBll().GetPageShareList();
}
通过业务逻辑层获取数据。
4. 阅读统计界面 WeixinPageIndex.aspx
前台：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WeixinPageIndex.aspx.cs" Inherits="Statistics.WeixinPageIndex" %>
"http://www.w3.org/1999/xhtml">
"server">
"Content-Type" content="text/html; charset=utf-8" />
利用JS-SDK来获取分享者，并通过Share页面来保存分享数据。
后台：
public partial class WeixinPageIndex : System.Web.UI.Page

}

ViewState["shareOpenId"] = shareOpenId;

保存访问者记录，识别访问者和分享者。
5. 处理文字请求
在CustomMessageHandler里处理文字请求，详细的使用方法可参考《用c#开发微信（2）扫描二维码，用户授权后获取用户基本信息 （源码下载）》：
public override IResponseMessageBase OnTextRequest(RequestMessageText requestMessage)
{
var responseMessage = CreateResponseMessage();
responseMessage.Articles.Add(new Article()
{
Title = "首页",
Description = "点击进入首页",
PicUrl = "",
Url = System.Configuration.ConfigurationManager.AppSettings["site"] + "/WeixinPageIndex.aspx?u=" + requestMessage.FromUserName
});
return responseMessage;
}
这里把访问者的OpenId带上，为了方便识别访问者和分享者。
所有界面如下：
