RsCode.WeChat中,接收到微信推送的消息，是通过IWeChatEventHandler类来处理的

收到微信消息后自定义逻辑

如果需要自定义收到微信消息的逻辑，可自定义类，并继承WeChatEventHandler,具体使用示例如下：

1. 自定义消息处理类CustomWxMsgHandler，继承WeChatEventHandler

2. 添加服务

services.AddScoped<IWeChatEventHandler, CustomWxMsgHandler>();

3. 示例代码

   public class CustomWxMsgHandler:WeChatEventHandler
   {
           //点击菜单要返回的事件,向用户发消息时，返回消息体加密后的字符串
        public override async Task<string> OnMenuClickEvent(MenuClickEventMessage menuClickEvent)
        {
            log.LogInformation("OnMenuClickEvent=" + JsonSerializer.Serialize(menuClickEvent));
           if (menuClickEvent.EventKey == "散财童子")
           {
               var fromUserName = menuClickEvent.FromUserName;
               var toUserName = menuClickEvent.ToUserName;
               TextMessage msg = new TextMessage(fromUserName, toUserName, "欢迎关注软商网络");
               var options = WeChatOptions.FirstOrDefault(c => c.Id == toUserName);
               wechat.UseAppId(options.AppId);
               var d = await wechat.SendMessageAsync<TextMessage>(msg);
               return d;
           }
           else
               return "success";
       }
       //微信后台推送的component_ticket
       public override async Task<string> OnComponentVerifyTicketEvent(ThirdPlatformMessage data)
       {
           var key = "component_verify_ticket";
           await cache.SetAsync(key,data,DateTime.Now.AddHours(11));//保存11个小时
           return "success";
       }
   }
