我运行 Nginx 和 PHP-FPM。Nginx 在 www-data 下运行，PHP-FPM 作为每个网站的单独用户运行。我使用 Nginx FASTCGI 缓存并使用 WordPress 的 Nginx Helper 插件。不幸的是，由于用户不同，我们不能在插件中使用“Purge All”功能，因为 php 用户无权访问缓存。
由于安全原因，更改权限不是一种选择。
如果 URL 中存在以下参数，我想要做的是使用不同的 PHP-FPM 池。
nginx_helper_urls=all
我当前的 NGinx 配置如下：
upstream examplebackend {
server unix:/var/run/php-fcgi-example.sock;
}
upstream cachedeletebackend {
server unix:/var/run/php-fcgi-cachedelete.sock;
}
server {
listen 80 default;
server_name www.example.com;
return 301 https://www.example.com$request_uri;
}

}
# Don't cache uris containing the following segments

# Don't use the cache for logged in users or recent commenters
if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") {
set $skip_cache 1;
}
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
try_files $uri =404;
include fastcgi_params;
if ( $args ~ nginx_helper_urls=all ) { fastcgi_pass cachedeletebackend; }
fastcgi_pass examplebackend;

}
location = /robots.txt { access_log off; log_not_found off; }
location ~ /\. { deny all; access_log off; log_not_found off; }
}
不知道我哪里出错了，或者是否有可能。谢谢
