如果用户仅在浏览器上直接访问图像文件，如何重定向？ [nginx]

Question

如果用户尝试仅在浏览器中直接访问图像文件，我该如何重定向？ 我想保留使用<img src="...">嵌入图像的能力。 如何从重定向

https://img.example.com/c/600x1200_90_webp/img-master/img/2022/01/03/08/04/54/95259215_p0_master1200.jpg

至

https://example.com/detail?id=95259215

这是我的 nginx conf

proxy_cache_path /var/www/img.example.com/htdocs/cache-store levels=1:2 keys_zone=pixstore:10m max_size=5g inactive=7d use_temp_path=off;
server {


    server_name img.example.com www.img.example.com;


    access_log /var/log/nginx/img.example.com.access.log ;
    error_log /var/log/nginx/img.example.com.error.log;

    add_header X-Proxy-Cache $upstream_cache_status;
    location / {
        proxy_cache pixstore;
        proxy_cache_revalidate on;
        proxy_cache_use_stale error timeout updating http_500 http_502 http_503 http_504;
        proxy_cache_lock on;
        add_header X-Cache-Status $upstream_cache_status;
        proxy_pass http://xxx.xxx.xxx.xxx:8090;
        proxy_redirect off;
        include proxy_params;
        add_header Access-Control-Allow-Origin *;
        proxy_cache_valid 200 7d;
        proxy_cache_valid 404 5m;
    }

location ~ "^/c/600x1200_90_webp/img-master/img/*/*/*/*/*/(?<filename>.+\.(jpg|png))$" {
    return 301 https://example.com/detail?id=$filename;
}


    # Security settings for better privacy
    # Deny hidden files
    location ~ /\.(?!well-known\/) {
        deny all;
    }
    # letsencrypt validation
    location /.well-known/acme-challenge/ {
        alias /var/www/html/.well-known/acme-challenge/;
        allow all;
        auth_basic off;
    }

    include /var/www/img.example.com/conf/nginx/*.conf;

}
