nginx 设置某个目录只允许访问指定后缀文件

server {
        listen 80;
        server_name your_domain.com;
         
        location /example_directory/ {
            # 允许访问 特定 后缀的文件
            location ~* \.(png|jpg|jpeg|PNG|JPG|JPEG)$ {
                allow all;
                try_files $uri $uri/ =404;
            }
         
            # 拒绝其他所有请求
            deny all;
        }
         
        # 其他配置...
