用c#开发微信 (8) 微渠道 - 推广渠道管理系统 3 UI设计及后台处理
我们可以使用微信的“生成带参数二维码接口”和 “用户管理接口”，来实现生成能标识不同推广渠道的二维码，记录分配给不同推广渠道二维码被扫描的信息。这样就可以统计和分析不同推广渠道的推广效果。
前面二篇《 用c#开发微信 (6) 微渠道 - 推广渠道管理系统 1 基础架构搭建 》， 《 用c#开发微信 (7) 微渠道 - 推广渠道管理系统 2 业务逻辑实现 》分别介绍了数据访问层和业务逻辑层。 本文是微渠道的第三篇，主要介绍如下内容：
1. 接收二维码扫描事件
2. 推广渠道类型管理
3. 推广渠道管理
4. 推广渠道二维码扫描记录列表
5. 下载渠道二维码
6. 微信用户列表
下面是详细的实现方法：
1. 接收二维码扫描事件
可参考前面的 《 用c#开发微信 (4) 基于Senparc.Weixin框架的接收事件推送处理 （源码下载） 》,这里就不过多讲解了：
/// <summary> /// 自定义MessageHandler /// 把MessageHandler作为基类，重写对应请求的处理方法 /// </summary> public partial class CustomMessageHandler : MessageHandler<MessageContext<IRequestMessageBase, IResponseMessageBase>>
{ /// <summary> /// 构造函数 /// </summary> /// <param name="inputStream"></param> /// <param name="maxRecordCount"></param> public CustomMessageHandler(Stream inputStream, int maxRecordCount = 0)
: base(inputStream, null, maxRecordCount)
{ //这里设置仅用于测试，实际开发可以在外部更全局的地方设置， //比如MessageHandler<MessageContext>.GlobalWeixinContext.ExpireMinutes = 3。 WeixinContext.ExpireMinutes = 3;
}
public override void OnExecuting()
{ //测试MessageContext.StorageData if (CurrentMessageContext.StorageData == null)
{ CurrentMessageContext.StorageData = 0;
}
base.OnExecuting(); }
public override void OnExecuted()
{ base.OnExecuted(); CurrentMessageContext.StorageData = ((int)CurrentMessageContext.StorageData) + 1; }
/// <summary> /// 处理扫描请求 /// 用户扫描带场景值二维码时，如果用户已经关注公众号，则微信会将带场景值扫描事件推送给开发者。 /// </summary> /// <returns></returns> public override IResponseMessageBase OnEvent_ScanRequest(RequestMessageEvent_Scan requestMessage)
{ int sceneId = 0; int.TryParse(requestMessage.EventKey, out sceneId);
if (sceneId > 0) { new ChannelScanBll().SaveScan(requestMessage.FromUserName, sceneId, ScanType.Scan); }
var responseMessage = CreateResponseMessage<ResponseMessageText>();
responseMessage.Content = "扫描已记录"; return responseMessage; }
/// <summary> /// 处理关注请求 /// 用户扫描带场景值二维码时，如果用户还未关注公众号，则用户可以关注公众号，关注后微信会将带场景值关注事件推送给开发者。 /// </summary> /// <returns></returns> public override IResponseMessageBase OnEvent_SubscribeRequest(RequestMessageEvent_Subscribe requestMessage)
{ if (!string.IsNullOrWhiteSpace(requestMessage.EventKey))
{ string sceneIdstr = requestMessage.EventKey.Substring(8); int sceneId = 0; int.TryParse(sceneIdstr, out sceneId);
if (sceneId > 0) { new ChannelScanBll().SaveScan(requestMessage.FromUserName, sceneId, ScanType.Subscribe); }
}
var responseMessage = CreateResponseMessage<ResponseMessageText>();
responseMessage.Content = "扫描已记录"; return responseMessage; }
public override IResponseMessageBase DefaultResponseMessage(IRequestMessageBase requestMessage)
{ //所有没有被处理的消息会默认返回这里的结果 var responseMessage = this.CreateResponseMessage<ResponseMessageText>(); responseMessage.Content = "这条消息来自DefaultResponseMessage。"; return responseMessage; }
}
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
2. 推广渠道类型管理
主要是对推广渠道类型的新增、修改、删除及列表显示等
1) 渠道新增、修改页面
前台：
<html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head1" runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>修改渠道类型</title>
</head>
<body>
<form id="Form1" class="form-horizontal" type="post" runat="server">
<%if (ViewState["channelType"] != null)
{%> <%-- 修改表单 --%>
<input type="hidden" name="ID" value="<%=(ViewState["channelType"] as ChannelSystem.ViewEntity.ChannelTypeEntity).ID%>" />

</div>
<%}
else {%> <%-- 新增表单 --%>
<div class="control-group">

后台：
/// <summary> /// 新增或修改渠道类型 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Page_Load(object sender, EventArgs e)

{ ViewState["channelType"] = new ChannelTypeBll().GetEntityById(id);
}
}
else { //将渠道类型新增或修改的数据保存到数据库 var entity = new ChannelTypeEntity() { ID = Request.Form["ID"] == null ? 0 : int.Parse(Request.Form["ID"]),
Name = Request.Form["Name"] };
new ChannelTypeBll().UpdateOrInsertEntity(entity); //回到渠道类型列表页面 Response.Redirect("ChannelTypeList.aspx"); Response.End();
}
}
2) 渠道类型列表页面

4. 推广渠道二维码扫描记录列表

5. 下载渠道二维码
后台：
/// <summary> /// 下载渠道二维码 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Page_Load(object sender, EventArgs e)
{ //获取渠道ID int id; if (int.TryParse(Request.QueryString["id"], out id))

Response.End();
}
}
6. 微信用户列表
前台：
<html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head1" runat="server">

<tbody>
<% foreach (ChannelSystem.ViewEntity.WeixinUserInfoEntity weixinUserInfo in (ViewState["WeixinUserInfoList"] as List<ChannelSystem.ViewEntity.WeixinUserInfoEntity>))

</form>
</div>
</body>
</html>
后台：
protected void Page_Load(object sender, EventArgs e)
{ //获取微信用户列表数据 ViewState["WeixinUserInfoList"] = new WeixinUserInfoBll().GetEntities();
}
上一篇，讲过同步微信用户的线程只会在这个页面第一次打开时被调用。
同样地，我们也要建一个Index页面作为入口：
private readonly string Token = ConfigurationManager.AppSettings["token"];//与微信公众账号后台的Token设置保持一致，区分大小写。
protected void Page_Load(object sender, EventArgs e)
{ string signature = Request["signature"];
string timestamp = Request["timestamp"];
string nonce = Request["nonce"];
string echostr = Request["echostr"];
if (Request.HttpMethod == "GET")
{ //get method - 仅在微信后台填写URL验证时触发 if (CheckSignature.Check(signature, timestamp, nonce, Token)) { WriteContent(echostr); //返回随机字符串则表示验证通过 }
else { WriteContent("failed:" + signature + "," + CheckSignature.GetSignature(timestamp, nonce, Token) + "。" +
"如果你在浏览器中看到这句话，说明此地址可以被作为微信公众账号后台的Url，请注意保持Token一致。"); }
Response.End();
}
else { //post method - 当有用户想公众账号发送消息时触发 if (!CheckSignature.Check(signature, timestamp, nonce, Token)) { WriteContent("参数错误！"); return; }
//设置每个人上下文消息储存的最大数量，防止内存占用过多，如果该参数小于等于0，则不限制 var maxRecordCount = 10;
//自定义MessageHandler，对微信请求的详细判断操作都在这里面。 var messageHandler = new CustomMessageHandler(Request.InputStream, maxRecordCount); try { //测试时可开启此记录，帮助跟踪数据，使用前请确保App_Data文件夹存在，且有读写权限。 messageHandler.RequestDocument.Save(
Server.MapPath("~/App_Data/" + DateTime.Now.Ticks + "_Request_" +
messageHandler.RequestMessage.FromUserName + ".txt")); //执行微信处理过程 messageHandler.Execute();
//测试时可开启，帮助跟踪数据 messageHandler.ResponseDocument.Save(
Server.MapPath("~/App_Data/" + DateTime.Now.Ticks + "_Response_" +
messageHandler.ResponseMessage.ToUserName + ".txt")); WriteContent(messageHandler.ResponseDocument.ToString());
return; }
catch (Exception ex) { //将程序运行中发生的错误记录到App_Data文件夹 using (TextWriter tw = new StreamWriter(Server.MapPath("~/App_Data/Error_" + DateTime.Now.Ticks + ".txt")))
{ tw.WriteLine(ex.Message);
tw.WriteLine(ex.InnerException.Message);
if (messageHandler.ResponseDocument != null)
{ tw.WriteLine(messageHandler.ResponseDocument.ToString());
}
tw.Flush();
tw.Close();
}
WriteContent(""); }
finally { Response.End();
}
}
}
private void WriteContent(string str)
{ Response.Output.Write(str);
}
最后整个View就如下图：
