apache、iis规则屏蔽拦截蜘蛛抓取

如果是正常的搜索引擎蜘蛛访问,不建议对蜘蛛进行禁止,否则网站在百度等搜索引擎中的收录和排名将会丢失,造成客户流失等损失。

可以优先考虑升级虚拟主机型号以获得更多的流量或升级为云服务器(不限流量)。更多详情请访问: http://www.yc-idc.net

Linux下规则文件.htaccess(手工创建.htaccess文件到站点根目录)

<IfModule mod_rewrite.c>
RewriteEngine On
#Block spider
RewriteCond %{HTTP_USER_AGENT} "Bytespider|Amazonbot|YisouSpider|ClaudeBot|GPTBot|meta-externalagent|SemrushBot|DotBot|BLEXBot|SMTBot|PetalBot|Apache-HttpClient|SemrushBot|Webdup|AcoonBot|AhrefsBot|Ezooms|EdisterBot|EC2LinkFinder|jikespider|Purebot|MJ12bot|WangIDSpider|WBSearchBot|Wotbox|xbfMozilla|Yottaa|YandexBot|Jorgee|SWEBot|spbot|TurnitinBot-Agent|mail.RU|curl|perl|Python|Wget|Xenu|ZmEu|^$" [NC]
RewriteRule !(^robots\.txt$) - [F]
</IfModule>

Windows2008、2012或更高系统下规则文件web.config (手工创建web.config文件到站点根目录)

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
   <rewrite>
    <rules>
     <rule name="Block spider">
      <match url="(^robots.txt$)" ignoreCase="false" negate="true" />
      <conditions>
      <add input="{HTTP_USER_AGENT}" pattern="Bytespider|Amazonbot|YisouSpider|ClaudeBot|GPTBot|meta-externalagent|SemrushBot|DotBot|BLEXBot|SMTBot|PetalBot|Apache-HttpClient|SemrushBot|Webdup|AcoonBot|AhrefsBot|Ezooms|EdisterBot|EC2LinkFinder|jikespider|Purebot|MJ12bot|WangIDSpider|WBSearchBot|Wotbox|xbfMozilla|Yottaa|YandexBot|Jorgee|SWEBot|spbot|TurnitinBot-Agent|mail.RU|curl|perl|Python|Wget|Xenu|ZmEu|^$" ignoreCase="true" />
      </conditions>
       <action type="AbortRequest"/>
     </rule>
    </rules>
   </rewrite>
  </system.webServer>
</configuration>
