微信公共平台中涉及到地理位置的有两种情况:
第一、我发送一个自选的地理位置给微信，然后微信可以自动反馈响应的信息。
第二、让微信获取我们GPS定位地址位置，反馈响应的信息。
首先我们先来看第一种，在微信中除了可以发文本，图片，语音等还有一个信息就是地理位置，按照微信接受地理信息的XML信息，我们需要改造一下之前的wxmessage类加上几个属性：
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 Recognition { get; set; }
public string MediaId { get; set; }
public string EventKey { get; set; }
public string Location_X { get; set; }
public string Location_Y { get; set; }
public string Scale { get; set; }
public string Label { get; set; }
} 其中Location_X代表纬度，Location_Y代表经度，Scale代表缩放比例，Label代表位置的描述
和接受文本，语音消息一下样，地理信息的MsgType为“location”，修改一下之前的GetWxMessage()函数和OnLoad里面的消息处理：
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() == "location")
{
wx.Location_X = xml.SelectSingleNode("xml").SelectSingleNode("Location_X").InnerText;
wx.Location_Y = xml.SelectSingleNode("xml").SelectSingleNode("Location_Y").InnerText;
wx.Scale = xml.SelectSingleNode("xml").SelectSingleNode("Scale").InnerText;
wx.Label = xml.SelectSingleNode("xml").SelectSingleNode("Label").InnerText;
}
if (wx.MsgType.Trim() == "event")
{
wx.EventName = xml.SelectSingleNode("xml").SelectSingleNode("Event").InnerText;
wx.EventKey = xml.SelectSingleNode("xml").SelectSingleNode("EventKey").InnerText;
}
if (wx.MsgType.Trim() == "voice")
{
wx.Recognition = xml.SelectSingleNode("xml").SelectSingleNode("Recognition").InnerText;
}
return wx;
}
protected void Page_Load(object sender, EventArgs e)
{
wxmessage wx = GetWxMessage();
string res = "";
if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "subscribe")
{
string content = "";
if (!wx.EventKey.Contains("qrscene_"))
{
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
{
content = "二维码参数：n" + wx.EventKey.Replace("qrscene_", "");
res = sendTextMessage(wx, content);
}
}
else if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.ToLower() == "scan")
{
string str = "二维码参数：n" + wx.EventKey;
res = sendTextMessage(wx, str);
}
else if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "CLICK")
{
if(wx.EventKey=="HELLO")
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
{
WriteLog(wx.MsgType);
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 if (wx.MsgType == "voice")
{
res = sendTextMessage(wx, wx.Recognition);
}
else if (wx.MsgType == "location")
{
res = sendTextMessage(wx, "您发送的位置是:" + wx.Label + ";纬度是:" + wx.Location_X + ";经度是:" + wx.Location_Y + ";缩放比例为:" + wx.Scale);
}
else
{
res = sendTextMessage(wx, "你好,未能识别消息!");
}
}
Response.Write(res);
}
