实现爬虫记录本文从创建crawler 数据库，robot.php记录来访的爬虫从而将信息插入数据库crawler,然后从数据库中就可以获得所有的爬虫信息。实现代码具体如下：

create table crawler ( crawler_ID bigint() unsigned not null auto_increment primary key, crawler_category varchar() not null, crawler_date datetime not null default '-- ::', crawler_url varchar() not null, crawler_IP varchar() not null)default charset=utf; |
以下文件 robot.php 记录来访的爬虫，并将信息写入数据库：

<?php $ServerName = $_SERVER["SERVER_NAME"] ; $ServerPort = $_SERVER["SERVER_PORT"] ; $ScriptName = $_SERVER["SCRIPT_NAME"] ; $QueryString = $_SERVER["QUERY_STRING"]; $serverip = $_SERVER["REMOTE_ADDR"] ; $Url="http://".$ServerName; if ($ServerPort != "") { $Url = $Url.":".$ServerPort ; } $Url=$Url.$ScriptName; if ($QueryString !="") { $Url=$Url."?".$QueryString; } $GetLocationURL=$Url ; $agent = $_SERVER["HTTP_USER_AGENT"]; $agent=strtolower($agent); $Bot =""; if (strpos($agent,"bot")>-) { $Bot = "Other Crawler"; } if (strpos($agent,"googlebot")>-) { $Bot = "Google"; } if (strpos($agent,"mediapartners-google")>-) { $Bot = "Google Adsense"; } if (strpos($agent,"baiduspider")>-) { $Bot = "Baidu"; } if (strpos($agent,"sogou spider")>-) { $Bot = "Sogou"; } if (strpos($agent,"yahoo")>-) { $Bot = "Yahoo!"; } if (strpos($agent,"msn")>-) { $Bot = "MSN"; } if (strpos($agent,"ia_archiver")>-) { $Bot = "Alexa"; } if (strpos($agent,"iaarchiver")>-) { $Bot = "Alexa"; } if (strpos($agent,"sohu")>-) { $Bot = "Sohu"; } if (strpos($agent,"sqworm")>-) { $Bot = "AOL"; } if (strpos($agent,"yodaoBot")>-) { $Bot = "Yodao"; } if (strpos($agent,"iaskspider")>-) { $Bot = "Iask"; } require("./dbinfo.php"); date_default_timezone_set('PRC'); $shijian=date("Y-m-d h:i:s", time()); // 连接到 MySQL 服务器 $connection = mysql_connect ($host, $username, $password); if (!$connection) { die('Not connected : ' . mysql_error()); } // 设置活动的 MySQL 数据库 $db_selected = mysql_select_db($database, $connection); if (!$db_selected) { die ('Can\'t use db : ' . mysql_error()); } // 向数据库插入数据 $query = "insert into crawler (crawler_category, crawler_date, crawler_url, crawler_IP) values ('$Bot','$shijian','$GetLocationURL','$serverip')"; $result = mysql_query($query); if (!$result) { die('Invalid query: ' . mysql_error()); }?> |
成功了，现在访问数据库即可得知什么时候哪里的蜘蛛爬过你的什么页面。

以上代码就是PHP代码实现爬虫记录——超管用的全部内容，希望对大家有所帮助。
