CAC SMart购物车身份验证Nginx服务器

Question

我想为我的网站使用CAC智能卡进行智能卡身份验证，服务器是nginx我已经有了https，并且我试图了解nginx服务器将如何检测我的智能卡证书

我的问题是，没有注释#ssl_client_certificate ;的行，服务器就无法工作，但是我不知道我必须在该行中指出什么路径？因为在配置服务器之前不会加载客户端证书，所以一旦检测到智能卡就将加载客户端证书？ 谢谢您的帮助

  server {

          listen 8443 ssl;
          ssl_certificate             /etc/nginx/cert.pem;
          ssl_certificate_key         /etc/nginx/key.pem;
          ssl_verify_client on;
          #ssl_client_certificate ;
          error_page                  500 502 503 504  /50x.html;
          location = /50x.html {
                        root /usr/share/nginx/html;

        }
  }
