nginx通过https和http提供静态文件

Question

所以，我想只保护我网站的登录和管理部分。问题是管理员使用一般站点上使用的一些常见静态文件。这意味着当我在管理员中时，这些文件应通过 https 提供，而当我在常规网站上时，应将其作为 http提供

如何配置nginx以这种方式运行？

到目前为止我使用的配置如下：

server {
    listen 80;
    server_name site.com www.site.com;
    root /home/site_folder/web;
    index index.php;

    location ~ /(get-involved|contribute|api) {
        return 301 https://$server_name$request_uri;
    }

    location ~ \.php$ {
        include /etc/nginx/fastcgi_params;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param HTTPS on;
        fastcgi_param SCRIPT_FILENAME /home/site_folder/web/index.php;
    }

    location / {
        root /home/site_folder/web;

        if (-f $request_filename) {
            expires max;
            break;
        }

        try_files $uri $uri/index.php;
        rewrite ^(.*) /index.php last;
    }
}

server {
    listen 443 ssl;

    ssl_certificate path_to_ssl.crt;
    ssl_certificate_key path_to_key.key;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:!aNULL:!MD5;

    server_name site.com www.site.com;
    root /home/site_folder/web;
    index index.php;

    location ~ /(get-involved|contribute|api) {
        root /home/site_folder/web;

        if (-f $request_filename) {
            expires max;
            break;
        }

        try_files $uri $uri/index.php;
        rewrite ^(.*) /index.php last;
    }

    location ~ \.php$ {
        include /etc/nginx/fastcgi_params;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param HTTPS on;
        fastcgi_param SCRIPT_FILENAME /home/site_folder/web/index.php;
    }

    location / {
        return 301 http://$server_name$request_uri;
    }
}
