nginx配置文件 #user nobody;
worker_processes 6;#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;#pid logs/nginx.pid;events {worker_connections 65535 ;

}
Java代码 // header 传入nginx里的key即可 就会指定到对应的目标server里URL url new URL(urlString);URLConnection connection url.openConnection();connection.setRequestProperty(X-Target-Server, header);验证方式 可以在响应头中查看具体访问的代理地址。
