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/:rose\n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);
}
这样当我们发送一个地理位置信息的时候就可以反馈响应的信息了。值得一提的是:这里的地理信息位置无需授权,因为自己发送的地理信息位置不一定是自己的真实位置,我们可以在输入界面进行任意选择,不会涉及隐私。 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; }
public string Latitude { get; set; }
public string Longitude { get; set; }
public string Precision { get; set; }
}
改造一下GetWxMessage()函数和OnLoad函数:
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;
WriteLog("MsgType:"+wx.MsgType);
if (wx.MsgType.Trim() == "event")
{
wx.EventName = xml.SelectSingleNode("xml").SelectSingleNode("Event").InnerText;
WriteLog(wx.EventName);
if (wx.EventName.ToUpper() == "LOCATION")
{
wx.Latitude = xml.SelectSingleNode("xml").SelectSingleNode("Latitude").InnerText;
wx.Longitude = xml.SelectSingleNode("xml").SelectSingleNode("Longitude").InnerText;
wx.Precision = xml.SelectSingleNode("xml").SelectSingleNode("Precision").InnerText;
}
else
{
wx.EventKey = xml.SelectSingleNode("xml").SelectSingleNode("EventKey").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() == "voice")
{
wx.Recognition = xml.SelectSingleNode("xml").SelectSingleNode("Recognition").InnerText;
}
return wx;
}
当MsgType为event的时候我们之前用到的是菜单的事件,现在我们需要加入其EventName为"LOCATION"的代码段,因为现在还没有涉及其他的event我后面就用else好了,后面我会把代码写的规范些。在这里分别给新增的三个属性赋值,然后修改一下Onload函数
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/:rose\n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 if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "LOCATION")
{
res = sendTextMessage(wx, "您的位置是经度:" + wx.Latitude + ",维度是:" + wx.Longitude+",地理经度为:"+wx.Precision);
}
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 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);
}
好了,完成,这样当你开启你的微信“获得用户位置信息”的时候微信平台会提醒你,是仅进入会话第一次获取,还是每个5秒获取一次,如果你选择了后者,你就会看到,每5秒会反馈给你一个地理位置的信息。微信公共服务平台开发(.Net 的实现)10-------地理位置,布布扣,bubuko.com
