nginx 服务器目录禁止索引

我是在 window 下用的 laragon 集成环境用来学习开发 laravel。启动 nginx 服务器可以打开 localhost:8080，但是打不开 WWW 目录下面的网站，也就是 XXX.dev ，会提示服务器拒绝连接请求。切换成 apache 服务器不存在该问题
错误日志提示：

2017/08/08 09:40:24 [error] 9928#9048: *4 directory index of "D:/laragon/www/poi/" is forbidden, client: 127.0.0.1, server: localhost, request: "GET /poi/ HTTP/1.1", host: "localhost:8080"


nginx.conf 的配置：

#user nobody;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;


events {
worker_connections 1024;
}
