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();
}
/// <summary>
/// 获取页面访问统计信息
/// </summary>
/// <returns></returns>
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);
List<PageNavEntity> temp = 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;
}
/// <summary>
/// 获取页面分享统计信息
/// </summary>
/// <returns></returns>
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);
List<PageShareEntity> temp = 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());
}
}
/// <summary>
/// 获取不含统计相关参数的页面地址
/// </summary>
/// <param name="url">网址</param>
/// <returns>不含统计相关参数的页面地址</returns>
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：

</div>
<script>
//图表参数
var pageNavChartOpts = {
getStatisticsUrl: 'Data.aspx?type=navChart', //读取数据的访问地址
titletext: "",

startyear: 0,
startmonth: 0,
startday: 0,
lineinterval: 3600 * 1000, //竖线以1小时为间隔显示
pointInterval: 3600 * 1000,//点以1小时为间隔显示
countArray: [],
formid: "page-nav-chart", //图表容器ID
seriesname: "访问次数",
unit: "次"
};
jQuery(function () {
//使用HighCharts绘制图表
highcharts.extFunction.PreDrawMethod = function (repJson) {
pageNavChartOpts.startyear = repJson.StartYear;
pageNavChartOpts.startmonth = repJson.StartMonth;
pageNavChartOpts.startday = repJson.StartDay;
highcharts.displayMode = repJson.DisplayMode;
pageNavChartOpts.lineinterval = repJson.LineInterval;
pageNavChartOpts.pointInterval = repJson.PointInterval;
};
highcharts.init(pageNavChartOpts);
});
</script>
</body>
</html>
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

};
wx.ready(function () {

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<ResponseMessageNews>();
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：
