iis环境下，如何限制屏蔽恶意搜索引擎爬虫禁止抓取网站？

IIS7/IIS8/IIS10及以上web服务请在网站根目录下创建web.config文件,并写入如下代码即可:

1. <?xml version="1.0" encoding="UTF-8"?>
   
2. <configuration>
   
3.   <system.webServer>
   
4.    <rewrite>
   
5.     <rules>
   
6.      <rule name="Block spider">
   
7.       <match url="(^robots.txt$)" ignoreCase="false" negate="true" />
   
8.       <conditions>
   
9.       <add input="{HTTP_USER_AGENT}" pattern="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" />
   
10.       </conditions>
    
11.        <action type="AbortRequest"/>
    
12.      </rule>
    
13.     </rules>
    
14.    </rewrite>
    
15.   </system.webServer>
    
16. </configuration>

IIS6请在isapi重写组件中添加以下规则:

1. #Block spider
   
2. RewriteCond %{HTTP_USER_AGENT} (MegaIndex|MegaIndex.ru|BLEXBot|Qwantify|qwantify|semrush|Semrush|serpstatbot|hubspot|python|Bytespider|Go-http-client|Java|PhantomJS|SemrushBot|Scrapy|Webdup|AcoonBot|AhrefsBot|Ezooms|EdisterBot|EC2LinkFinder|jikespider|Purebot|MJ12bot|WangIDSpider|WBSearchBot|Wotbox|xbfMozilla|Yottaa|YandexBot|Jorgee|SWEBot|spbot|TurnitinBot-Agent|mail.RU|perl|Python|Wget|Xenu|ZmEu|^$) [NC]
   
3. RewriteRule !(^/robots.txt$) - [F]
