這篇文章主要介紹了如何通過微信公眾平臺實現(xiàn)在線客服機器人功能，具有一定借鑒價值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。
通過微信公眾平臺實現(xiàn)在線客服機器人功能。主要的功能包括：簡單對話、查詢天氣等服務。
當微信用戶關注公眾賬號時，可以給其適當?shù)奶崾尽？梢允菤g迎詞，可以是幫助提示。
直接上代碼：
class EventHandler : IHandler
{ /// <summary>
/// 請求的xml /// </summary>
private string RequestXml { get; set; } /// <summary>
/// 構造函數(shù) /// </summary>
/// <param name="requestXml"></param>
public EventHandler(string requestXml)
{ this.RequestXml = requestXml;
} /// <summary>
/// 處理請求 /// </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 = "歡迎您關注***，我是大哥大，有事就問我，呵呵！\n\n";
response = tm.GenerateContent();
} return response;
}
}簡單的交流問候，比如你好、幫助等等，跟我們使用微信聊天一樣，不過回應是由我們的程序響應。具體功能，可以根據(jù)自己的需要進行添加。
微信本來就是溝通的平臺。這個案例，可以用于在線服務機器人，類似于淘寶的客服機器人，可是我們這個是微信版的。呵呵
其實，很簡單，獲取請求消息，根據(jù)關鍵字來匹配回應。當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>
/// 請求的XML /// </summary>
private string RequestXml { get; set; } /// <summary>
/// 構造函數(shù) /// </summary>
/// <param name="requestXml">請求的xml</param>
public TextHandler(string requestXml)
{ this.RequestXml = requestXml;
} /// <summary>
/// 處理請求 /// </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; //進行發(fā)送者、接收者轉換
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，試試其他關鍵字吧。";
} return response;
}
}這個功能需要請求實時查詢的，請求官方的天氣發(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。
用戶請求，只需輸入：tq 城市名稱/拼音/首字母，即可獲取消息。
回復的消息：（以北京為例）
北京 2013年11月6日 星期三 今天：(17℃~4℃)晴北風4-5級轉3-4級4-5級轉3-4級 24小時穿衣指數(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℃)晴轉多云微風小于3級 48小時穿衣指數(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。
來看源碼吧：
