Question

我正在将Nginx与fastcgi缓存一起使用。我想在我的网站上使用安全标头。我已经在虚拟主机配置中添加了add header字段，但是除非我在fastcgi_main.conf文件中禁用add_header X-fastcgi cache $ upstream缓存状态，否则我将无法获得任何标题。 virualhost文件：

    }
   include /etc/nginx/bots.d/blockbots.conf;
   include /etc/nginx/bots.d/ddos.conf;
   include /etc/nginx/skip_cache.conf ;
   include /etc/nginx/purge_location.conf ;
   include /etc/nginx/gzip_location.conf ;
   include /etc/nginx/security_wp.conf;
        add_header Referrer-Policy 'origin';
        add_header "X-Frame-Options: sameorigin" always;
    location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass  unix:/var/run/php/php7.3-fpm.sock;
    include "/etc/nginx/customfastcgi" ;
    proxy_connect_timeout 300;
    proxy_send_timeout 300;
    proxy_read_timeout 300;
    send_timeout 300;
#    underscores_in_headers on;
client_max_body_size 256M;
    include /etc/nginx/fastcgi_main.conf ;
    }

}

FASTCGI_main.conf

        fastcgi_no_cache $skip_cache;
        fastcgi_cache phpcache;
        fastcgi_cache_valid 200 1m;
        fastcgi_cache_valid 301 1m;
        fastcgi_cache_valid 302 1m;
        fastcgi_cache_valid 307 1m;
        fastcgi_cache_valid 404 1m;
        fastcgi_cache_use_stale error timeout invalid_header http_500 http_503;
        fastcgi_cache_min_uses 1;
        fastcgi_cache_methods GET HEAD;
        fastcgi_ignore_headers Cache-Control Expires Set-Cookie;
       add_header X-FastCGI-Cache $upstream_cache_status;
    ```

RESULT:
curl -I https://dev-kuhicbury.$domain

您已踏入add_header指令的一个非常常见的配置陷阱。与NGINX中的所有其他类似数组的指令类似，如果当前上下文中没有其他add_header，则仅继承。

典型的解决方案是（通过不可避免的复制）将所需的标头复制粘贴（在特定位置）：

在FASTCGI_main.conf中：

        fastcgi_no_cache $skip_cache;
        fastcgi_cache phpcache;
        fastcgi_cache_valid 200 1m;
        fastcgi_cache_valid 301 1m;
        fastcgi_cache_valid 302 1m;
        fastcgi_cache_valid 307 1m;
        fastcgi_cache_valid 404 1m;
        fastcgi_cache_use_stale error timeout invalid_header http_500 http_503;
        fastcgi_cache_min_uses 1;
        fastcgi_cache_methods GET HEAD;
        fastcgi_ignore_headers Cache-Control Expires Set-Cookie;
        add_header X-FastCGI-Cache $upstream_cache_status;
        add_header Referrer-Policy 'origin';
        add_header "X-Frame-Options: sameorigin" always;

NGINX的这种非直觉行为已成为许多问题的根源。

这里有一些有趣的模块，可以解决相同的问题（例如，“更好的add_header”）：

ngx_headers_more
ngx_security_headers，更适合您的情况
