我的管理中的Nginx URL重写规则

登录到后端后如何重写URL？我需要将以下内容从www.domain.com/administration/index.php，www.domain.com/administration/nextpage.php更改为www.domain.com/administration/index，www.domain.com/administration/nextpage 这是我的实际配置：

server {
    server_name domain.com;
    return 301 $scheme://www.domain.com$request_uri;
}

server {
        listen 80;
        root /usr/share/nginx/www;
        index index.php;
        server_name www.domain.com;



   location / {
        rewrite ^([^\.]*)$ /$1.php;
    }

    location = / {
        rewrite ^ /index.php;
    }


    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
    }

    location ~ /\.ht {
            deny all;
      }
}

---

当实际URI失败时，将尝试添加扩展名

PHP

location /administration {
  try_files $uri $uri/ /$uri.php$is_args$query_string;
}

将该块添加到配置中将从/administration请求中删除.php

location /administration { 
    rewrite ^([^\.]*)(\.php)?$ /$1; 
}
