微信机器人开发教程的实例详解
微信公众平台开发教程（四） 实例入门：机器人(附源码)上一篇文章，写了基本框架，可能很多人会觉得晕头转向，这里提供一个简单的例子来予以说明，希望能帮你解开谜团。 一、功能介绍通过微信公众平台实现在线客服机器人功能。主要的功能包括：简单对话、查询天气等服务。 这里只是提供比较简单的功能，重在通过此实例来说明公众平台的具体研发过程。只是一个简单DEMO，如果需要的话可以在此基础上进行扩展。 当然后续我们还会推出比较复杂的应用实例。 二、具体实现1、提供访问接口这里不再赘述，参照上一章，微信公众账号开发教程（二） 基础框架搭建 2、签名认证和分发请求这里不再赘述，参照上一章，微信公众账号开发教程（二） 基础框架搭建 3、处理请求，并响应1）关注当微信用户关注公众账号时，可以给其适当的提示。可以是欢迎词，可以是帮助提示。 直接上代码： class EventHandler : IHandler { /// <summary> /// 请求的xml /// </summary> private string RequestXml { get; set; } /// <summary> /// 构造函数 /// </summary> /// <param name="requestXml"></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.Event.Equals("subscribe",StringComparison.OrdinalIgnoreCase)) { //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"; response = tm.GenerateContent(); } return response; } }2）问候简单的交流问候，比如你好、帮助等等，跟我们使用微信聊天一样，不过回应是由我们的程序响应。具体功能，可以根据自己的需要进行添加。 代码如下： /// <summary> /// 文本信息处理类 /// </summary> public class TextHandler : IHandler { /// <summary> /// 请求的XML /// </summary> private string RequestXml { get; set; } /// <summary> /// 构造函数 /// </summary> /// <param name="requestXml">请求的xml</param> public TextHandler(string requestXml) { this.RequestXml = requestXml; } /// <summary> /// 处理请求 /// </summary> /// <returns></returns> public string HandleRequest() { string response = string.Empty; TextMessage tm = TextMessage.LoadFromXml(RequestXml); string content = tm.Content.Trim(); if (string.IsNullOrEmpty(content)) { response = "您什么都没输入，没法帮您啊，%>_<%。"; } else { if (content.StartsWith("tq", StringComparison.OrdinalIgnoreCase)) { string cityName = content.Substring(2).Trim(); response = WeatherHelper.GetWeather(cityName); } else { response = HandleOther(content); } } tm.Content = response; //进行发送者、接收者转换 string temp = tm.ToUserName; tm.ToUserName = tm.FromUserName; tm.FromUserName = temp; response = tm.GenerateContent(); return response; } /// <summary> /// 处理其他消息 /// </summary> /// <param name="tm"></param> /// <returns></returns> private string HandleOther(string requestContent) { string response = string.Empty; if (requestContent.Contains("你好") || requestContent.Contains("您好")) { response = "您也好~"; } else if (requestContent.Contains("傻")) { response = "我不傻！哼~ "; } else if (requestContent.Contains("逼") || requestContent.Contains("操")) { response = "哼，你说脏话！ "; } else if (requestContent.Contains("是谁")) { response = "我是大哥大，有什么能帮您的吗？~"; } else if (requestContent.Contains("再见")) { response = "再见！"; } else if (requestContent.Contains("bye")) { response = "Bye！"; } else if (requestContent.Contains("谢谢")) { response = "不客气！嘿嘿"; } else if (requestContent == "h" || requestContent == "H" || requestContent.Contains("帮助")) { response = @"查询天气，输入tq 城市名称/拼音/首字母"; } else { response = "您说的，可惜，我没明白啊，试试其他关键字吧。"; } return response; } }3）查询天气这个功能需要请求实时查询的，请求官方的天气发布网站，然后解析其返回值，按照我们需要的格式，组织天气信息，最后发送给微信客户。 回复的消息：（以北京为例） 北京2013年11月6日 星期三今天：(17℃~4℃)晴北风4-5级转3-4级4-5级转3-4级24小时穿衣指数:天气冷，建议着棉服、羽绒服、皮夹克加羊毛衫等冬季服装。年老体弱者宜着厚棉衣、冬大衣或厚羽绒服。明天：(14℃~3℃)晴转多云微风小于3级48小时穿衣指数:天气冷，建议着棉服、羽绒服、皮夹克加羊毛衫等冬季服装。年老体弱者宜着厚棉衣、冬大衣或厚羽绒服。 来看源码吧： class WeatherHelper { /// <summary> /// 城市集合字段 /// </summary> private static Dictionary<string, City> mCities;
