首先建立一个微信消息类。
class wxmessage {
public string FromUserName { get; set; } public string ToUserName { get; set; }
public string MsgType { get; set; } public string EventName { get; set; }
public string Content { get; set; } public string EventKey { get; set; }
}
后台代码如下
protected void Page_Load(object sender, EventArgs e) {
wxmessage wx = GetWxMessage(); string res = "";
if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "subscribe")
{//刚关注时的时间，用于欢迎词 string content = "";
content = "/:rose欢迎北京永杰友信科技有限公司/:rosen直接回复“你好”"; res = sendTextMessage(wx, content);
} else
{ if (wx.MsgType == "text" && wx.Content == "你好")
{ res = sendTextMessage(wx, "你好,欢迎使用北京永杰友信科技有限公司公共微信平台!");
} else
{ res = sendTextMessage(wx, "你好,未能识别消息!");
} }
Response.Write(res);
}
private wxmessage GetWxMessage() {
wxmessage wx = new wxmessage(); StreamReader str = new StreamReader(Request.InputStream, System.Text.Encoding.UTF8);
XmlDocument xml = new XmlDocument(); xml.Load(str);
wx.ToUserName = xml.SelectSingleNode("xml").SelectSingleNode("ToUserName").InnerText; wx.FromUserName = xml.SelectSingleNode("xml").SelectSingleNode("FromUserName").InnerText;
wx.MsgType = xml.SelectSingleNode("xml").SelectSingleNode("MsgType").InnerText; if (wx.MsgType.Trim() == "text")
{ wx.Content = xml.SelectSingleNode("xml").SelectSingleNode("Content").InnerText;
} if (wx.MsgType.Trim() == "event")
{ wx.EventName = xml.SelectSingleNode("xml").SelectSingleNode("Event").InnerText;
}
return wx;
}
/// /// 发送文字消息
/// /// 获取的收发者信息
