微信公眾平臺(tái)開發(fā)教程（四）實(shí)例入門：機(jī)器人回復(fù)(附源碼)

更新時(shí)間：2016年12月02日 10:11:44 作者：停留的風(fēng)

本篇文章主要介紹了微信公眾平臺(tái)開發(fā)機(jī)器人，可以實(shí)現(xiàn)簡(jiǎn)單對(duì)話和查詢天氣等，有需要的可以了解一下。

上一篇文章，寫了基本框架，可能很多人會(huì)覺得暈頭轉(zhuǎn)向，這里提供一個(gè)簡(jiǎn)單的例子來予以說明，希望能幫你解開謎團(tuán)。

一、功能介紹

通過微信公眾平臺(tái)實(shí)現(xiàn)在線客服機(jī)器人功能。主要的功能包括：簡(jiǎn)單對(duì)話、查詢天氣等服務(wù)。

這里只是提供比較簡(jiǎn)單的功能，重在通過此實(shí)例來說明公眾平臺(tái)的具體研發(fā)過程。只是一個(gè)簡(jiǎn)單DEMO，如果需要的話可以在此基礎(chǔ)上進(jìn)行擴(kuò)展。

當(dāng)然后續(xù)我們還會(huì)推出比較復(fù)雜的應(yīng)用實(shí)例。

二、具體實(shí)現(xiàn)

1、提供訪問接口

這里不再贅述，參照上一章，微信公眾賬號(hào)開發(fā)教程（二）基礎(chǔ)框架搭建
http://www.dhdzp.com/article/98754.htm

2、簽名認(rèn)證和分發(fā)請(qǐng)求

這里不再贅述，參照上一章，微信公眾賬號(hào)開發(fā)教程（二）基礎(chǔ)框架搭建
http://www.dhdzp.com/article/98754.htm

3、處理請(qǐng)求，并響應(yīng)

1）關(guān)注

當(dāng)微信用戶關(guān)注公眾賬號(hào)時(shí)，可以給其適當(dāng)?shù)奶崾??？梢允菤g迎詞，可以是幫助提示。

直接上代碼：

class EventHandler : IHandler
  {
    /// <summary>
    /// 請(qǐng)求的xml
    /// </summary>
    private string RequestXml { get; set; }
    /// <summary>
    /// 構(gòu)造函數(shù)
    /// </summary>
    /// <param name="requestXml"></param>
    public EventHandler(string requestXml)
    {
      this.RequestXml = requestXml;
    }
    /// <summary>
    /// 處理請(qǐng)求
    /// </summary>
    /// <returns></returns>
    public string HandleRequest()
    {
      string response = string.Empty;
      EventMessage em = EventMessage.LoadFromXml(RequestXml);
      if (em.Event.Equals("subscribe",StringComparison.OrdinalIgnoreCase))
      {
        //回復(fù)歡迎消息
        TextMessage tm = new TextMessage();
        tm.ToUserName = em.FromUserName;
        tm.FromUserName = em.ToUserName;
        tm.CreateTime = Common.GetNowTime();
        tm.Content = "歡迎您關(guān)注***，我是大哥大，有事就問我，呵呵！\n\n";
        response = tm.GenerateContent();
      }

      return response;
    }
  }

2）問候

簡(jiǎn)單的交流問候，比如你好、幫助等等，跟我們使用微信聊天一樣，不過回應(yīng)是由我們的程序響應(yīng)。具體功能，可以根據(jù)自己的需要進(jìn)行添加。

微信本來就是溝通的平臺(tái)。這個(gè)案例，可以用于在線服務(wù)機(jī)器人，類似于淘寶的客服機(jī)器人，可是我們這個(gè)是微信版的。呵呵
其實(shí)，很簡(jiǎn)單，獲取請(qǐng)求消息，根據(jù)關(guān)鍵字來匹配回應(yīng)。當(dāng)然這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。

代碼如下：

/// <summary>
  /// 文本信息處理類
  /// </summary>
  public class TextHandler : IHandler
  {
    /// <summary>
    /// 請(qǐng)求的XML
    /// </summary>
    private string RequestXml { get; set; }
    /// <summary>
    /// 構(gòu)造函數(shù)
    /// </summary>
    /// <param name="requestXml">請(qǐng)求的xml</param>
    public TextHandler(string requestXml)
    {
      this.RequestXml = requestXml;
    }
    /// <summary>
    /// 處理請(qǐng)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 = "您什么都沒輸入，沒法幫您啊，%>_<%。";
      }
      else
      {
        if (content.StartsWith("tq", StringComparison.OrdinalIgnoreCase))
        {
          string cityName = content.Substring(2).Trim();
          response = WeatherHelper.GetWeather(cityName);
        }
        else
        {
          response = HandleOther(content);
        }
      }
      tm.Content = response;
      //進(jìn)行發(fā)送者、接收者轉(zhuǎn)換
      string temp = tm.ToUserName;
      tm.ToUserName = tm.FromUserName;
      tm.FromUserName = temp;
      response = tm.GenerateContent();
      return response;
    }
    /// <summary>
    /// 處理其他消息
    /// </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，你說臟話！ ";
      }
      else if (requestContent.Contains("是誰"))
      {
        response = "我是大哥大，有什么能幫您的嗎？~";
      }
      else if (requestContent.Contains("再見"))
      {
        response = "再見！";
      }
      else if (requestContent.Contains("bye"))
      {
        response = "Bye！";
      }
      else if (requestContent.Contains("謝謝"))
      {
        response = "不客氣！嘿嘿";
      }
      else if (requestContent == "h" || requestContent == "H" || requestContent.Contains("幫助"))
      {
        response = @"查詢天氣，輸入tq 城市名稱\拼音\首字母";
      }
      else
      {
        response = "您說的，可惜，我沒明白啊，試試其他關(guān)鍵字吧。";
      }

      return response;
    }
  }

3）查詢天氣

這個(gè)功能需要請(qǐng)求實(shí)時(shí)查詢的，請(qǐng)求官方的天氣發(fā)布網(wǎng)站，然后解析其返回值，按照我們需要的格式，組織天氣信息，最后發(fā)送給微信客戶。

采用文本消息方式處理。

用戶請(qǐng)求，只需輸入：tq 城市名稱/拼音/首字母，即可獲取消息。

回復(fù)的消息：（以北京為例）

北京
2013年11月6日星期三
今天：(17℃~4℃)晴北風(fēng)4-5級(jí)轉(zhuǎn)3-4級(jí)4-5級(jí)轉(zhuǎn)3-4級(jí)
24小時(shí)穿衣指數(shù):天氣冷，建議著棉服、羽絨服、皮夾克加羊毛衫等冬季服裝。年老體弱者宜著厚棉衣、冬大衣或厚羽絨服。
明天：(14℃~3℃)晴轉(zhuǎn)多云微風(fēng)小于3級(jí)
48小時(shí)穿衣指數(shù):天氣冷，建議著棉服、羽絨服、皮夾克加羊毛衫等冬季服裝。年老體弱者宜著厚棉衣、冬大衣或厚羽絨服。
