新建文件agent_deny.conf，添加一下內(nèi)容：
#禁止Scrapy等工具的抓取
if ($http_user_agent ~* (Scrapy|Curl|HttpClient)) {
return 403;
}
#禁止指定UA及UA為空的訪問
if ($http_user_agent ~* "FeedDemon|Indy Library|Alexa Toolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedParser|ApacheBench|Microsoft URL Control|Swiftbot|ZmEu|oBot|jaunty|Python-urllib|lightDeckReports Bot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms|^$" ) {
return 403;
}
#禁止非GET|HEAD|POST方式的抓取
if ($request_method !~ ^(GET|HEAD|POST)$) {
return 403;
}
修改nginx配置文件，在需要處理的server中包含該文件，include agent_deny.conf（注意路徑）
附上常見的爬蟲UA，這個是在github上找到別人整理好的，還支持驗證，大叫有興趣的話可以自己去看看
部分UA：
