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

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：

/// 请求的xml /// private string RequestXml { get; set; } ///

/// 构造函数 ///

/// public EventHandler(string requestXml) { this.RequestXml = requestXml; } ///

/// 处理请求 ///

/// 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。

微信本来就是沟通的平台。这个案例，可以用于在线服务机器人，类似于淘宝的客服机器人，可是我们这个是微信版的。呵呵其实，很简单，获取请求消息，根据关键字来匹配回应。当然这里可能要做的工作很多，如何支持智能匹配，如何支持模糊匹配等。

代码如下：

/// 文本信息处理类 /// public class TextHandler : IHandler { ///

/// 请求的XML ///

private string RequestXml { get; set; } ///

/// 构造函数 ///

/// public TextHandler(string requestXml) { this.RequestXml = requestXml; } ///

/// 处理请求 ///

/// 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; } ///

/// 处理其他消息 ///

/// /// 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。

采用文本消息方式处理。

用户请求，只需输入：tq 城市名称/拼音/首字母，即可获取消息。

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：

/// 城市集合字段 /// private static Dictionary mCities; ///

/// 城市集合 ///

public static Dictionary Cities { get { if (mCities == null) { LoadCities(); }

    return mCities;
  }
}
/// <summary>
/// 加载城市
/// </summary>
private static void LoadCities()
{
  mCities = new Dictionary<string,City>();
  mCities.Clear();
  mCities.Add("101010100",new City() { Code = "101010100",Name = "北京",PinYin = "beijing",FristLetter = "bj" });
  mCities.Add("101020100",new City() { Code = "101020100",Name = "上海",PinYin = "shanghai",FristLetter = "sh" });
  mCities.Add("101200101",new City() { Code = "101200101",Name = "武汉",PinYin = "wuhai",FristLetter = "wh" });

}

                where item.Value != null

                      || item.Value.PinYin.Equals(name,StringComparison.OrdinalIgnoreCase) 
                      || item.Value.FristLetter.Equals(name,StringComparison.OrdinalIgnoreCase))
                select item.Value.Code;
  if (codes != null && codes.Count() > 0)
  {
    cityCode = codes.First<string>();
  }

  //http请求，<a href="/tag/huoqu/" target="_blank" class="keywords">获取</a>天气
  if (!string.IsNullOrEmpty(cityCode))

    StreamReader reader = new StreamReader(response.GetResponseStream(),Encoding.UTF8);
    string weahterInfo = reader.ReadToEnd();
    if (string.IsNullOrEmpty(weahterInfo))
    {
      result = "暂时没有取到<a href="/tag/tianqishuju/" target="_blank" class="keywords">天气数据</a>,请稍后再试";
    }
    else
    {
      XmlDocument doc = JsonConvert.DeserializeXmlNode(weahterInfo);
      if (doc != null)
      {
        XmlNode node = doc.DocumentElement;
        if (node != null)
        {
          StringBuilder builder = new StringBuilder();
          builder.Append(node["city"].InnerText).Append("\n");
