稍微研究了一下，服务器如何获取用户的信息做了一个整理。
cs代码 通过反射来访问类的实例属性和属性值
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Text;
using System.Reflection;
using System.Text.RegularExpressions;
namespace Whoru
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
System.Web.HttpBrowserCapabilities bCaps;
// 请求者的浏览器信息
bCaps = Request.Browser;
// 获取bCaps对象的类型
Type type = bCaps.GetType();
object obj = Activator.CreateInstance(type);
// 属性信息数组
PropertyInfo[] props = type.GetProperties();
string str = string.Empty;
// 遍历实例的所有属性，及属性值
foreach (PropertyInfo pi in props)
{
// 属性名
string name = pi.Name;
try
{
str += string.Format("{0}：{1}", pi.Name, pi.GetValue(bCaps, null).ToString());
str += "<br>";
}
catch (Exception ex)
{
//Response.Write("error:"+ex.Message);
str += "<br>";
}
}
// 为了加强准确性，防止支持wap的浏览器如opera，加入操作系统验证。openwave|后为pc操作系统
// Chrome浏览器有点捣蛋，它的agent信息里会包括Mozilla，Chrome，Safari等信息，所以必要时要做一些特殊的判断
string osPat = "mozilla|m3gate|winwap|openwave|Windows NT|Windows 3.1|95|Blackcomb|98|ME|X Window|Longhorn|ubuntu|AIX|Linux|AmigaOS|BEOS|HP-UX|OpenBSD|FreeBSD|NetBSD|OS/2|OSF1|SUN";
string osMob = "Android|iPhone|iPod|iPad|Windows Phone|MQQBrowser";
string uAgent = Request.ServerVariables["HTTP_USER_AGENT"];
Regex reg = new Regex(osPat);
Regex regMob = new Regex(osMob);
if (reg.IsMatch(uAgent))
{
str += "电脑访问";
}
else if (regMob.IsMatch(uAgent))
{
str += "手机访问";
}
else
{
str += "未知的设备";
}
str += "<br/>" + uAgent;
divContent.InnerHtml = str;
}
}
}
html代码
把div定义为服务器控件，然后在后台把信息输出。
