另外通过接口window.navigator.platform获得的结果：
UC浏览器为：Linux,ARM7
其它浏览器为：Linux armv7l
结论：
以上经过测试的浏览器中，以移动设备模式（包括iPad模式）浏览时，User Agent字符串中总会包含关键字“Mobile”，以桌面模式（电脑版）浏览时，User Agent字符串中都不含“Mobile"。

第3篇 由于移动流量日趋增多，我们统计网站流量的时候，需要把移动和PC的流量分开，而遇到百度蜘蛛的时候，为了更好更细的统计，也需要把百度蜘蛛的移动端和PC端分别来统计，这对网站分析有着非常重要的意义。
本文提供判断百度移动蜘蛛和百度PC蜘蛛的源代码，有php、asp、asp.net三个版本。 php版 <?php $ua=$_SERVER['HTTP_USER_AGENT']; $ua=strtolower($ua); if($ua!="" && strpos($ua,"baiduspider")){ if(strpos($ua,"android") || strpos($ua,"mobile")){ echo "是百度移动UA"; }else{ echo "是百度PCUA"; } } else{ echo"不是baiduspider UA"; } ?> 这个代码比较简单一点，这里为大家推荐看下这篇文章http://www.jb51.net/article/72211.htm。 asp版 <% ua=Request.ServerVariables("HTTP_USER_AGENT") ua=LCase(ua) if ua<>"" and InStr(ua,"baiduspider")<>0 then if InStr(ua,"android")<>0 or InStr(ua,"mobile")<>0 then response.write "是百度移动 UA" else response.write"是百度PC UA" end if else response.write "不是baiduspiderUA" end if %> 继续为大家推荐个asp中判断是否为搜索引擎的代码： function isspider() dim i,agent,searray agent="agent:"&LCase(request.servervariables("http_user_agent")) searray=array("googlebot","baiduspider","sogouspider","yahoo","Sosospider") isspider= false for i=0 to ubound(searray) if (instr(agent,searray(i))>0) then isspider=true next end function asp.net string ua = Request.ServerVariables["HTTP_USER_AGENT"]; ua=ua.ToLower (); if(ua != "" && ua.IndexOf("baiduspider") > -1){ if (ua.IndexOf("android") > -1 || ua.IndexOf("mobile") > -1) { Response .Write("是百度移动 UA"); } else{ Response .Write("是百度PC UA"); } } else{ Response .Write("不是baiduspiderUA"); } string agent = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_USER_AGENT"]; if (agent == null) { Response.Write("Other"); } else { Response.Write(agent); } 以上demo是通过ua来判断来访者是否Baiduspider，是比较普遍的方法。

For user OS system type, you can use User-Agent in request headers:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/93.0.4577.63 Safari/537.36 Edg/93.0.961.38For example the above value means Windows 10 x64 edition.
As there are many browsers and many system types and versions, it is not easy to do a holistic parsing. What you can do is to find out the most useful ones for you based on each browser User-Agent definitions.
For client local user machine name, it is not sent to the server in the request unless you are using Windows Authentication. Even for this authentication type, it doesn't necessarily represent the actual user name as user can use Run As to impersonate users.
