php/asp/asp.net中判断百度移动和PC蜘蛛的实现代码

 <"" && 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";
    }

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。
