接上篇，看ResponseXML(postString);方法如下
/// <summary>
/// 获取用户发送的消息
/// </summary>
/// <param name="postString"></param>
private void ResponseXML(string postString)
{
//使用XMLDocument加载信息结构
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(postString);
XmlElement rootElement = xmlDoc.DocumentElement;//获取文档的根
XmlNode MsgType = rootElement.SelectSingleNode("MsgType"); //获取消息的文本类型
RequestXML requestXML = new RequestXML();//声明实例，获取各个属性并赋值
requestXML.ToUserName = rootElement.SelectSingleNode("ToUserName").InnerText;//公众号
requestXML.FromUserName = rootElement.SelectSingleNode("FromUserName").InnerText;//用户
requestXML.CreateTime = rootElement.SelectSingleNode("CreateTime").InnerText;//创建时间
requestXML.MsgType = MsgType.InnerText;//消息类型
///对消息的不同类型进行赋值
if (requestXML.MsgType == "text")
{
//赋值文本信息内容
requestXML.Content = rootElement.SelectSingleNode("Content").InnerText;
}
if (requestXML.MsgType.Trim() == "location")
{
///赋值地理位置纬度，经度，地图缩放比例，地理位置说明
requestXML.Location_X = rootElement.SelectSingleNode("Location_X").InnerText;
requestXML.Location_Y = rootElement.SelectSingleNode("Location_Y").InnerText;
requestXML.Scale = rootElement.SelectSingleNode("Scale").InnerText;
requestXML.Label = rootElement.SelectSingleNode("Label").InnerText;
}
if (requestXML.MsgType.Trim().ToLower() == "event")
{
///赋值事件名称和事件key值
requestXML.EventName = rootElement.SelectSingleNode("Event").InnerText;
requestXML.EventKey = rootElement.SelectSingleNode("EventKey").InnerText;
}
ResponseMsg(requestXML);
}
requestXML是我单独创建的一个类，该类声明了消息中常用的属性字段，如下：
/// <summary>
/// 接收消息的实体类
/// </summary>
public class RequestXML
{
private String toUserName = String.Empty;
/// <summary>
/// 本公众号
/// </summary>
public String ToUserName{get;set;}
/// <summary>
/// 用户微信号
/// </summary>
public String FromUserName{get;set;}
/// <summary>
/// 创建时间
/// </summary>
public String CreateTime{get;set;}
/// <summary>
/// 信息类型
/// </summary>
public String MsgType{get;set;}
/// <summary>
/// 信息内容
/// </summary>
public String Content{get;set;}
/*以下为事件类型的消息特有的属性*/
/// <summary>
/// 事件名称
/// </summary>
public String EventName{get;set;}
/// <summary>
/// 事件值
/// </summary>
public string EventKey { get; set; }
/*以下为图文类型的消息特有的属性*/
/// <summary>
/// 图文消息的个数
/// </summary>
public int ArticleCount { get; set; }
/// <summary>
/// 图文消息的标题
/// </summary>
public string Title { get; set; }
/// <summary>
/// 图文消息的简介
/// </summary>
public string Description { get; set; }
/// <summary>
/// 图文消息图片的链接地址
/// </summary>
public string PicUrl { get; set; }
/// <summary>
/// 图文消息详情链接地址
/// </summary>
public string Url { get; set; }
/// <summary>
/// 图文消息集合
/// </summary>
public List<RequestXML> Articles { get; set;}
/*以下为地理位置类型的消息特有的属性*/
/// <summary>
/// 地理位置纬度
/// </summary>
public String Location_X { get; set; }
/// <summary>
/// 地理位置经度
/// </summary>
public String Location_Y { get; set; }
/// <summary>
/// 地图缩放比例
/// </summary>
public String Scale { get; set; }
/// <summary>
/// 地图位置说明
/// </summary>
public String Label { get; set; }
}
继续关注 ResponseMsg(requestXML);方法如下,
private void ResponseMsg(RequestXML requestXML)
{
string MsgType = requestXML.MsgType;
try
{
//根据消息类型判断发送何种类型消息
switch (MsgType)
{
case "text":
SendTextCase(requestXML);//发送文本消息
break;
case "event"://发送事件消息
if (!string.IsNullOrWhiteSpace(requestXML.EventName) && requestXML.EventName.ToString().Trim().Equals("subscribe"))
{
SendWelComeMsg(requestXML);//关注时返回的图文消息
}
else if (!string.IsNullOrWhiteSpace(requestXML.EventName) && requestXML.EventName.ToString().Trim().Equals("CLICK"))
{
SendEventMsg(requestXML);//发送事件消息
}
break;
case "location"://发送位置消息
SendMapMsg(requestXML);
break;
default:
break;
}
}
catch (Exception ex)
{
HttpContext.Current.Response.Write(ex.ToString());
}
}
先来关注发送文本消息，SendTextCase(requestXML);//发送文本消息
/// <summary>
/// 发送文本
/// </summary>
/// <param name="requestXML"></param>
private void SendTextCase(RequestXML requestXML)
{
string responseContent = FormatTextXML(requestXML.FromUserName, requestXML.ToUserName, requestXML.Content);
HttpContext.Current.Response.ContentType = "text/xml";
HttpContext.Current.Response.ContentEncoding = Encoding.UTF8;
HttpContext.Current.Response.Write(responseContent);
HttpContext.Current.Response.End();
}
FormatTextXML方法制定格式
/// <summary>
/// 返回格式化的Xml格式内容
/// </summary>
/// <param name="p1">公众号</param>
/// <param name="p2">用户号</param>
/// <param name="p3">回复内容</param>
/// <returns></returns>
private string FormatTextXML(string p1, string p2, string p3)
{
return "<xml><ToUserName><![CDATA[" + p1 + "]]></ToUserName><FromUserName><![CDATA[" + p2 + "]]></FromUserName><CreateTime>" + DateTime.Now.Subtract(new DateTime(1970, 1, 1, 8, 0, 0)).TotalSeconds.ToString() + "</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[" + p3 + "]]></Content><FuncFlag>1</FuncFlag></xml>";
}
这样就能实现消息的应答，如果用户点击的按钮，如下代码：
case "event"://发送事件消息
if
(!string.IsNullOrWhiteSpace(requestXML.EventName) &&
requestXML.EventName.ToString().Trim().Equals("subscribe"))
{
SendWelComeMsg(requestXML);//关注时返回的图文消息
}
else if (!string.IsNullOrWhiteSpace(requestXML.EventName) &&
requestXML.EventName.ToString().Trim().Equals("CLICK"))
{
SendEventMsg(requestXML);//发送事件消息
}
break;
/// <summary>
/// 发送响应事件消息
/// </summary>
/// <param name="requestXML"></param>
private void SendEventMsg(RequestXML requestXML)
{
string keyStr = requestXML.EventKey.ToString();
switch (keyStr)
{
case "mypay":
SendPayDetails(requestXML);//发送薪资账单
break;
case "tianqiyubao":
SendWeaterMessage(requestXML);//发送天气预报
break;
case "kaixinyixiao":
SendKaiXinMessage(requestXML);//发送开心一笑结果集
break;
case "updateMessage":
SendUpdateMessage(requestXML);//发送修改信息链接
break;
case "yuangonghuodong":
SendYuanGongHuoDong(requestXML);//发送学生活动
break;
case "yuangongtongzhi":
SendYuanGongTongZhi(requestXML);//发送员工通知
break;
case "youwenbida":
SendWenti(requestXML);//发送员工提交问题链接
break;
case "mywen":
SendWentiList(requestXML);//发送问题列表链接
break;
case "PhoneSerices":
SendKeFuMessage(requestXML);//接入客服
break;
default:
String responseContent = String.Empty;
responseContent = FormatTextXML(requestXML.FromUserName, requestXML.ToUserName,"此功能暂未开放！敬请期待！");
HttpContext.Current.Response.ContentType = "text/xml";
HttpContext.Current.Response.ContentEncoding = Encoding.UTF8;
HttpContext.Current.Response.Write(responseContent);
HttpContext.Current.Response.End();
break;
}
}
SendWelComeMsg(requestXML);//关注时返回的图文消息
/// <summary>
/// 发送关注时的图文消息
/// </summary>
/// <param name="requestXML"></param>
private void SendWelComeMsg(RequestXML requestXML)
{
String responseContent = String.Empty;
string newdate = DateTime.Now.Subtract(new DateTime(1970, 1, 1, 8, 0, 0)).TotalSeconds.ToString();
string PUrlfileName = "http://www.deqiaohr.com.cn/weixin/welcome.jpg";
responseContent = string.Format(Message_News_Main, requestXML.FromUserName, requestXML.ToUserName, newdate, "1",
string.Format(Message_News_Item, "欢迎关注德桥员工服务中心", "苏州德桥人力资源创立于2002年...", PUrlfileName, "http://www.deqiaohr.com.cn/weixin/WxGsjianjie.aspx"));
HttpContext.Current.Response.ContentType = "text/xml";
HttpContext.Current.Response.ContentEncoding = Encoding.UTF8;
HttpContext.Current.Response.Write(responseContent);
HttpContext.Current.Response.End();
}
Message_News_Main 和Message_News_Item是图文消息格式化
/// <summary>
/// 返回图文消息主体
/// </summary>
public static string Message_News_Main
{
get
{
return @"<xml>
<ToUserName><![CDATA[{0}]]></ToUserName>
<FromUserName><![CDATA[{1}]]></FromUserName>
<CreateTime>{2}</CreateTime>
<MsgType><![CDATA[news]]></MsgType>
<ArticleCount>{3}</ArticleCount>
<Articles>
{4}
</Articles>
</xml> ";
}
}
/// <summary>
/// 返回图文消息项
/// </summary>
public static string Message_News_Item
{
get
{
return @"<item>
<Title><![CDATA[{0}]]></Title>
<Description><![CDATA[{1}]]></Description>
<PicUrl><![CDATA[{2}]]></PicUrl>
<Url><![CDATA[{3}]]></Url>
</item>";
}
}
