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：

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);
}
