using System; using System.Xml.Linq; using Newtonsoft.Json; namespace Yank.WeiXin.Robot.Utility { class XmlUtility { /// <summary> /// /// </summary> /// <param></param> /// <param></param> /// <returns></returns> public static XDocument ParseJson(string json,string rootName) { return JsonConvert.DeserializeXNode(json, rootName); } } }
5、事件处理
设置了菜单，这下需要处理事件了。跟我们之前设计ASPX或者WinForm一样，都要绑定按钮的事件。这里只是通过XML消息将请求传递过来。
通过“2、设置菜单"中具体的菜单内容，我们便已经知道需要进行哪些事件处理了。对于按钮类型为view的，无须处理，它会自动跳转至指定url.
需要处理的点击事件：
1）赞一下
2）查询某城市的天气，北京、上海、武汉
3）帮助
这个还要沿用上章中的事件处理器EventHandler来扩展处理。
具体的实现代码吧：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using Yank.WeiXin.Robot.Messages; namespace Yank.WeiXin.Robot.Handlers { class EventHandler : IHandler { /// <summary> /// 请求的xml /// </summary> private string RequestXml { get; set; } /// <summary> /// 构造函数 /// </summary> /// <param></param> public EventHandler(string requestXml) { this.RequestXml = requestXml; } /// <summary> /// 处理请求 /// </summary> /// <returns></returns> public string HandleRequest() { string response = string.Empty; EventMessage em = EventMessage.LoadFromXml(RequestXml); if (em != null) { switch (em.Event.ToLower()) { case ("subscribe"): response = SubscribeEventHandler(em); break; case "click": response = ClickEventHandler(em); break; } } return response; } /// <summary> /// 关注 /// </summary> /// <param></param> /// <returns></returns> private string SubscribeEventHandler(EventMessage em) { //回复欢迎消息 TextMessage tm = new TextMessage(); tm.ToUserName = em.FromUserName; tm.FromUserName = em.ToUserName; tm.CreateTime = Common.GetNowTime(); tm.Content = "欢迎您关注***，我是大哥大，有事就问我，呵呵！\n\n"; return tm.GenerateContent(); } /// <summary> /// 处理点击事件 /// </summary> /// <param></param> /// <returns></returns> private string ClickEventHandler(EventMessage em) { string result = string.Empty; if (em != null && em.EventKey != null) { switch (em.EventKey.ToUpper()) { case "BTN_GOOD": result = btnGoodClick(em); break; case "BTN_TQ_BEIJING": result = searchWeather("beijing", em); break; case "BTN_TQ_SHANGHAI": result = searchWeather("shanghai", em); break; case "BTN_TQ_WUHAN": result = searchWeather("wuhai", em); break; case "BTN_HELP": result = btnHelpClick(em); break; } } return result; } /// <summary> /// 赞一下 /// </summary> /// <param></param> /// <returns></returns> private string btnGoodClick(EventMessage em) { //回复欢迎消息 TextMessage tm = new TextMessage(); tm.ToUserName = em.FromUserName; tm.FromUserName = em.ToUserName; tm.CreateTime = Common.GetNowTime(); tm.Content = @"谢谢您的支持！"; return tm.GenerateContent(); } /// <summary> /// 帮助 /// </summary> /// <param></param> /// <returns></returns> private string btnHelpClick(EventMessage em) { //回复欢迎消息 TextMessage tm = new TextMessage(); tm.ToUserName = em.FromUserName; tm.FromUserName = em.ToUserName; tm.CreateTime = Common.GetNowTime(); tm.Content = @"查询天气，输入tq 城市名称\拼音\首字母"; return tm.GenerateContent(); } /// <summary> /// 查询天气 /// </summary> /// <param></param> /// <param></param> /// <returns></returns> private string searchWeather(string cityName, EventMessage em) { TextMessage tm = new TextMessage(); tm.Content = WeatherHelper.GetWeather(cityName); //进行发送者、接收者转换 tm.ToUserName = em.FromUserName; tm.FromUserName = em.ToUserName; tm.CreateTime = Common.GetNowTime(); return tm.GenerateContent(); } } }
