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
<"" && 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"; } "_blank" href="https://www.jb51.net/article/72211.htm">https://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 functionasp.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。

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。
据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
