nginx禁止垃圾蜘蛛访问

现在很多ai蜘蛛，大数据蜘蛛，天天偷偷抓取网站信息，不给流量也罢。
关键是没底线：来了就不走，一直反复抓取，浪费大量服务器资源，如果您有需要，立刻屏蔽吧：

/zzzyk.com/nginx/conf文件夹下建立zzzyk_deny.conf文件
nginx配置文件里加入include zzzyk_deny.conf;

server
{
    include zzzyk_deny.conf;

    listen 80;

#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为空的访问
if ($http_user_agent ~ "opensiteexplorer|BLEXBot|MauiBot|SemrushBot|DotBot|WinHttp|WebZIP|FetchURL|node-superagent|java/|yisouspider|FeedDemon|Jullo|JikeSpider|Indy Library|Alexa Toolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|Java|Feedly|Apache-HttpAsyncClient|UniversalFeedParser|ApacheBench|M

#禁止非GET|HEAD|POST方式的抓取
if ($request_method !~ ^(GET|HEAD|POST)$) {
    return 403;

}
