上一篇文章,寫了基本框架,可能很多人會(huì)覺(jué)得暈頭轉(zhuǎn)向,這里提供一個(gè)簡(jiǎn)單的例子來(lái)予以說(shuō)明,希望能幫你解開(kāi)謎團(tuán)。
通過(guò)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(guò)此實(shí)例來(lái)說(shuō)明公眾平臺(tái)的具體研發(fā)過(guò)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。
這里不再贅述,參照上一章,微信公眾賬號(hào)開(kāi)發(fā)教程(二) 基礎(chǔ)框架搭建

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(wèn)我,呵呵!\n\n"; response = tm.GenerateContent(); } return response; } }
簡(jiǎn)單的交流問(wèn)候,比如你好、幫助等等,跟我們使用微信聊天一樣,不過(guò)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(lái)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(lái)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(méi)輸入,沒(méi)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(shuō)臟話! "; } else if (requestContent.Contains("是誰(shuí)")) { response = "我是大哥大,有什么能幫您的嗎?~"; } else if (requestContent.Contains("再見(jiàn)")) { response = "再見(jiàn)!"; } 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(shuō)的,可惜,我沒(méi)明白啊,試試其他關(guān)鍵字吧。"; } return response; } }
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。
