一、Apache

①、通過修改 .htaccess 文件

修改網(wǎng)站目錄下的.htaccess，添加如下代碼即可(2 種代碼任選)：

可用代碼 (1)：

RewriteEngineOnRewriteCond%{HTTp_USER_AGENT}(^$|FeedDemon|IndyLibrary|AlexaToolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedparser|ApacheBench|MicrosoftURLControl|Swiftbot|ZmEu|oBot|jaunty|python–urllib|lightDeckReportsBot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms)[NC]RewriteRule^(.*)$–[F]

可用代碼 (2)：

SetEnvIfNoCase^User–Agent$.*(FeedDemon|IndyLibrary|AlexaToolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedparser|ApacheBench|MicrosoftURLControl|Swiftbot|ZmEu|oBot|jaunty|python–urllib|lightDeckReportsBot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms)BADBOTOrderAllow,DenyAllowfromallDenyfromenv=BADBOT

②、通過修改 httpd.conf 配置文件

找到如下類似位置，根據(jù)以下代碼 新增 / 修改，然后重啟 Apache 即可：

Shell

DocumentRoot/home/wwwroot/xxx<Directory“/home/wwwroot/xxx”>SetEnvIfNoCaseUser–Agent“.*(FeedDemon|IndyLibrary|AlexaToolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedparser|ApacheBench|MicrosoftURLControl|Swiftbot|ZmEu|oBot|jaunty|python-urllib|lightDeckReportsBot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms)”BADBOTOrderallow,denyAllowfromalldenyfromenv=BADBOT</Directory>

二、Nginx 代碼

進(jìn)入到 nginx 安裝目錄下的 conf 目錄，將如下代碼保存為 agent_deny.conf

cd/usr/local/nginx/confvimagent_deny.conf

#禁止Scrapy等工具的抓取if($http_user_agent~*(Scrapy|Curl|HttpClient)){return403;}#禁止指定UA及UA為空的訪問if($http_user_agent~*“FeedDemon|IndyLibrary|AlexaToolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedparser|ApacheBench|MicrosoftURLControl|Swiftbot|ZmEu|oBot|jaunty|python-urllib|lightDeckReportsBot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms|^$”){return403;}#禁止非GET|HEAD|pOST方式的抓取if($request_method!~^(GET|HEAD|pOST)$){return403;}

然后，在網(wǎng)站相關(guān)配置中的 location / { 之后插入如下代碼：

Shell

includeagent_deny.conf;

如下的配置：

Shell

[marsge@Mars_Server~]$cat/usr/local/nginx/conf/zhangge.conflocation/{try_files$uri$uri//index.php?$args;#這個(gè)位置新增1行：includeagent_deny.conf;rewrite^/sitemap_360_sp.txt$/sitemap_360_sp.phplast;rewrite^/sitemap_baidu_sp.xml$/sitemap_baidu_sp.phplast;rewrite^/sitemap_m.xml$/sitemap_m.phplast;

保存后，執(zhí)行如下命令，平滑重啟 nginx 即可：

Shell

/usr/local/nginx/sbin/nginx–sreload

三、pHp 代碼

將如下方法放到貼到網(wǎng)站入口文件 index.php 中的第一個(gè)

pHp

//獲取UA信息$ua=$_SERVER[‘HTTp_USER_AGENT’];//將惡意USER_AGENT存入數(shù)組$now_ua=array(‘FeedDemon‘,‘BOT/0.1(BOTforJCE)’,‘CrawlDaddy‘,‘Java’,‘Feedly’,‘UniversalFeedparser’,‘ApacheBench’,‘Swiftbot’,‘ZmEu’,‘IndyLibrary’,‘oBot’,‘jaunty’,‘YandexBot’,‘AhrefsBot’,‘MJ12bot’,‘WinHttp’,‘EasouSpider’,‘HttpClient’,‘MicrosoftURLControl’,‘YYSpider’,‘jaunty’,‘python-urllib’,‘lightDeckReportsBot’);//禁止空USER_AGENT，dedecms等主流采集程序都是空USER_AGENT，部分sql注入工具也是空USER_AGENTif(!$ua){header(“Content-type:text/html;charset=utf-8”);die(‘請(qǐng)勿采集本站，因?yàn)椴杉恼鹃L(zhǎng)木有小JJ！’);}else{foreach($now_uaas$value)//判斷是否是數(shù)組中存在的UAif(eregi($value,$ua)){header(“Content-type:text/html;charset=utf-8”);die(‘請(qǐng)勿采集本站，因?yàn)椴杉恼鹃L(zhǎng)木有小JJ！’);}}

四、測(cè)試效果

如果是 VpS，那非常簡(jiǎn)單，使用 curl -A 模擬抓取即可，比如：

模擬宜搜蜘蛛抓?。?/p>

Shell

curl–I–A‘YisouSpider’bizhi.bcoderss.com

模擬 UA 為空的抓取：

Shell

curl–I–A”bizhi.bcoderss.com

模擬百度蜘蛛的抓?。?/p>

Shell

curl–I–A‘Baiduspider’bizhi.bcoderss.com
