微信公共服务平台开发（.Net 的实现）3-------发送文本消息

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/:rose\n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;
}

/// <summary>
/// 发送文字消息
/// </summary>
/// <param name="wx">获取的收发者信息
/// <param name="content">内容
/// <returns></returns>
private string sendTextMessage(wxmessage wx, string content)
{
string res = string.Format(@" ",
wx.FromUserName, wx.ToUserName, DateTime.Now, content);
return res;
}
