asp.net实现识别客户端浏览器或操作系统


            1、通过 UserAgent







protected void Page_Load(object sender, EventArgs e)

  {

    //验证终端

    string agent = Request.Headers["User-Agent"];

    if (choose_net(agent))

    {

      Response.Redirect("/mobile/");

    }

  }



  //验证终端

  public bool choose_net(String userAgent)

  {

    if (userAgent.IndexOf("Noki") > -1 || // Nokia phones and emulators  

         userAgent.IndexOf("Eric") > -1 || // Ericsson WAP phones and emulators  

         userAgent.IndexOf("WapI") > -1 || // Ericsson WapIDE 2.0  

         userAgent.IndexOf("MC21") > -1 || // Ericsson MC218  

         userAgent.IndexOf("AUR") > -1 || // Ericsson R320  

         userAgent.IndexOf("R380") > -1 || // Ericsson R380  

         userAgent.IndexOf("UP.B") > -1 || // UP.Browser  

         userAgent.IndexOf("WinW") > -1 || // WinWAP browser  

         userAgent.IndexOf("UPG1") > -1 || // UP.SDK 4.0  

         userAgent.IndexOf("upsi") > -1 || //another kind of UP.Browser  

         userAgent.IndexOf("QWAP") > -1 || // unknown QWAPPER browser  

         userAgent.IndexOf("Jigs") > -1 || // unknown JigSaw browser  

         userAgent.IndexOf("Java") > -1 || // unknown Java based browser  

         userAgent.IndexOf("Alca") > -1 || // unknown Alcatel-BE3 browser (UP based)  

 

 

         userAgent.IndexOf("MITS") > -1 || // unknown Mitsubishi browser  

         userAgent.IndexOf("MOT-") > -1 || // unknown browser (UP based)  

         userAgent.IndexOf("My S") > -1 ||// unknown Ericsson devkit browser   

         userAgent.IndexOf("WAPJ") > -1 ||//Virtual WAPJAG www.wapjag.de  

         userAgent.IndexOf("fetc") > -1 ||//fetchpage.cgi Perl script from www.wapcab.de

 

  

         userAgent.IndexOf("ALAV") > -1 || //yet another unknown UP based browser  

         userAgent.IndexOf("Wapa") > -1 || //another unknown browser (Web based

 

"Wapalyzer")  

         userAgent.IndexOf("UCWEB") > -1 || //another unknown browser (Web based

 

"Wapalyzer")  

         userAgent.IndexOf("BlackBerry") > -1 || //another unknown browser (Web

 

based "Wapalyzer")          

         userAgent.IndexOf("J2ME") > -1 || //another unknown browser (Web based

 

"Wapalyzer")       

         userAgent.IndexOf("Oper") > -1 ||

         userAgent.IndexOf("Android") > -1 ||

      userAgent.IndexOf("mozilla") > -1)

    {

      return true;

    }

    else

    {

      return false;

    }

  }



2.考虑asp.net mvc 



里面有for mobile的模版

3.获取浏览器的属性

复制代码 代码如下:HttpBrowserCapabilities bc=Request.Browser; Response.Write("<script language='javascript'>alert('" + bc.Browser + "');</script>");

 4.js判断





<script type="text/javascript">

    var bro = navigator.userAgent;

    //alert(bro);

    // alert(bro.indexOf("Windows Phone"));

    // iPad 浏览器navigator.userAgent（包含iPad）

    if (bro.indexOf("NetFront") > 0 || bro.indexOf("UCWEB") > 0

      || bro.indexOf("iPhone") > 0 || bro.indexOf("Windows CE") > 0

      || bro.indexOf("MIDP-2.0") > 0 || bro.indexOf("Android") > 0

      || bro.indexOf("Opera Mini") > 0 || bro.indexOf("SymbianOS") > 0

      || bro.indexOf("Windows Phone") > 0) {

      window.open("Wap1/Index.aspx", "_top");

    }

    //    else if (bro.indexOf("Windows NT") > 0) {

    //      window.open("NewWeb/default.html", "_top");

    //    }

        else {

          window.open("NewWeb/default.html", "_top");

        }

  </script>







我们再来看下如何获取PC端的客户端信息呢





/// <summary>

/// 获取操作系统的名字

/// </summary>

/// <param name="userAgent"></param>

/// <returns></returns>

private string GetOSNameByUserAgent(string userAgent)

{

	string osVersion = "未知";

 

	if (userAgent.Contains("NT 10.0"))

	{

		osVersion = "Windows 10";

	}

	else if (userAgent.Contains("NT 6.3"))

	{

		osVersion = "Windows 8.1";

	}

	else if (userAgent.Contains("NT 6.2"))

	{

		osVersion = "Windows 8";

	}

	else if (userAgent.Contains("NT 6.1"))

	{

		osVersion = "Windows 7";

	}

	else if (userAgent.Contains("NT 6.1"))

	{

		osVersion = "Windows 7";

	}

	else if (userAgent.Contains("NT 6.0"))

	{

		osVersion = "Windows Vista/Server 2008";

	}

	else if (userAgent.Contains("NT 5.2"))

	{

		if (userAgent.Contains("64"))

			osVersion = "Windows XP";

		else

			osVersion = "Windows Server 2003";

	}

	else if (userAgent.Contains("NT 5.1"))

	{

		osVersion = "Windows XP";

	}

	else if (userAgent.Contains("NT 5"))

	{

		osVersion = "Windows 2000";

	}

	else if (userAgent.Contains("NT 4"))

	{

		osVersion = "Windows NT4";

	}

	else if (userAgent.Contains("Me"))

	{

		osVersion = "Windows Me";

	}

	else if (userAgent.Contains("98"))

	{

		osVersion = "Windows 98";

	}

	else if (userAgent.Contains("95"))

	{

		osVersion = "Windows 95";

	}

	else if (userAgent.Contains("Mac"))

	{

		osVersion = "Mac";

	}

	else if (userAgent.Contains("Unix"))

	{

		osVersion = "UNIX";

	}

	else if (userAgent.Contains("Linux"))

	{

		osVersion = "Linux";

	}

	else if (userAgent.Contains("SunOS"))

	{

		osVersion = "SunOS";

	}

	else

	{

		osVersion = HttpContext.Current.Request.Browser.Platform;

	}

	return osVersion;

}



基本上很全了，小伙伴们根据需求自由选择吧
