使用php来实现:
1、推荐的一种方法:php判断搜索引擎蜘蛛爬虫还是人为访问代码,摘自Discuz x3.2
<?phpfunction checkrobot($useragent=''){static $kw_spiders = array('bot', 'crawl', 'spider' ,'slurp', 'sohu-search', 'lycos', 'robozilla');static $kw_browsers = array('msie', 'netscape', 'opera', 'konqueror', 'mozilla');$useragent = strtolower(empty($useragent) ? $_SERVER['HTTP_USER_AGENT'] : $useragent);if(strpos($useragent, 'http://') === false && dstrpos($useragent, $kw_browsers)) return false;if(dstrpos($useragent, $kw_spiders)) return true;return false;}function dstrpos($string, $arr, $returnvalue = false) {if(empty($string)) return false;foreach((array)$arr as $v) {if(strpos($string, $v) !== false) {$return = $returnvalue ? $v : true;return $return;}}return false;}if(checkrobot()){echo '机器人爬虫';}else{echo '人';}?>
实际应用中可以这样判断,直接不是搜索引擎才执行操作
<?phpif(!checkrobot()){//do something}?>
2、第二种方法:
使用PHP实现蜘蛛访问日志统计
$useragent = addslashes(strtolower($_SERVER['HTTP_USER_AGENT']));if (strpos($useragent, 'googlebot')!== false){$bot = 'Google';}elseif (strpos($useragent,'mediapartners-google') !== false){$bot = 'Google Adsense';}elseif (strpos($useragent,'baiduspider') !== false){$bot = 'Baidu';}elseif (strpos($useragent,'sogou spider') !== false){$bot = 'Sogou';}elseif (strpos($useragent,'sogou web') !== false){$bot = 'Sogou web';}elseif (strpos($useragent,'sosospider') !== false){$bot = 'SOSO';}elseif (strpos($useragent,'360spider') !== false){$bot = '360Spider';}elseif (strpos($useragent,'yahoo') !== false){$bot = 'Yahoo';}elseif (strpos($useragent,'msn') !== false){$bot = 'MSN';}elseif (strpos($useragent,'msnbot') !== false){$bot = 'msnbot';}elseif (strpos($useragent,'sohu') !== false){$bot = 'Sohu';}elseif (strpos($useragent,'yodaoBot') !== false){$bot = 'Yodao';}elseif (strpos($useragent,'twiceler') !== false){$bot = 'Twiceler';}elseif (strpos($useragent,'ia_archiver') !== false){$bot = 'Alexa_';}elseif (strpos($useragent,'iaarchiver') !== false){$bot = 'Alexa';}elseif (strpos($useragent,'slurp') !== false){$bot = '雅虎';}elseif (strpos($useragent,'bot') !== false){$bot = '其它蜘蛛';}if(isset($bot)){$fp = @fopen('bot.txt','a');fwrite($fp,date('Y-m-d H:i:s')."\t".$_SERVER["REMOTE_ADDR"]."\t".$bot."\t".'http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"]."\r\n");fclose($fp);}
3、第三种方法:
我们可以通过HTTP_USER_AGENT来判断是否是蜘蛛,搜索引擎的蜘蛛都有自己的独特标志,下面列取了一部分。
function is_crawler() {$userAgent = strtolower($_SERVER['HTTP_USER_AGENT']);$spiders = array('Googlebot', // Google 爬虫'Baiduspider', // 百度爬虫'Yahoo! Slurp', // 雅虎爬虫'YodaoBot', // 有道爬虫'msnbot' // Bing爬虫// 更多爬虫关键字);foreach ($spiders as $spider) {$spider = strtolower($spider);if (strpos($userAgent, $spider) !== false) {return true;}}return false;}
下面的php代码附带了更多的蜘蛛标识
function isCrawler() {echo $agent= strtolower($_SERVER['HTTP_USER_AGENT']);if (!empty($agent)) {$spiderSite= array("TencentTraveler","Baiduspider+","BaiduGame","Googlebot","msnbot","Sosospider+","Sogou web spider","ia_archiver","Yahoo! Slurp","YoudaoBot","Yahoo Slurp","MSNBot","Java (Often spam bot)","BaiDuSpider","Voila","Yandex bot","BSpider","twiceler","Sogou Spider","Speedy Spider","Google AdSense","Heritrix","Python-urllib","Alexa (IA Archiver)","Ask","Exabot","Custo","OutfoxBot/YodaoBot","yacy","SurveyBot","legs","lwp-trivial","Nutch","StackRambler","The web archive (IA Archiver)","Perl tool","MJ12bot","Netcraft","MSIECrawler","WGet tools","larbin","Fish search",);foreach($spiderSite as $val) {$str = strtolower($val);if (strpos($agent, $str) !== false) {return true;}}} else {return false;}}if (isCrawler()){echo "你好蜘蛛精!";}else{echo "你不是蜘蛛精啊!";}
4、第四种方法:
<?php$flag = false;$tmp = $_SERVER['HTTP_USER_AGENT'];if(strpos($tmp, 'Googlebot') !== false){$flag = true;} else if(strpos($tmp, 'Baiduspider') >0){$flag = true;} else if(strpos($tmp, 'Yahoo! Slurp') !== false){$flag = true;} else if(strpos($tmp, 'msnbot') !== false){$flag = true;} else if(strpos($tmp, 'Sosospider') !== false){$flag = true;} else if(strpos($tmp, 'YodaoBot') !== false || strpos($tmp, 'OutfoxBot') !== false){$flag = true;} else if(strpos($tmp, 'Sogou web spider') !== false || strpos($tmp, 'Sogou Orion spider') !== false){$flag = true;} else if(strpos($tmp, 'fast-webcrawler') !== false){$flag = true;} else if(strpos($tmp, 'Gaisbot') !== false){$flag = true;} else if(strpos($tmp, 'ia_archiver') !== false){$flag = true;} else if(strpos($tmp, 'altavista') !== false){$flag = true;} else if(strpos($tmp, 'lycos_spider') !== false){$flag = true;} else if(strpos($tmp, 'Inktomi slurp') !== false){$flag = true;}if($flag == false){header("Location: //www.jb51.net" . $_SERVER['REQUEST_URI']);// 自动转到//www.jb51.net 对应的网页// $_SERVER['REQUEST_URI'] 为域名后面的路径// 或换成header("Location: //www.jb51.net/abc/d.php");exit();}?>
5、另外,还可以使用js来实现:
<script type="text/javascript">if(window.name != 'ad_app6'){var r = document.referrer;r = r.toLowerCase(); //转为小写var aSites = new Array('google.','baidu.','soso.','so.','360.','yahoo.','youdao.','sogou.','gougou.');var b = false;for (i in aSites){if (r.indexOf(aSites[i]) > 0){b = true;break;}}if(b){self.location = '要跳转的网址';window.adworkergo = 'ad_app6';}}</script>
