如果是apache服务器的话，在httpd-vhosts.conf文件中加上

<VirtualHost *:80>

   ServerAdmin webmaster@iwebshop.com

   DocumentRoot "F:/www/test"

   ServerName xxx.test.com

   ErrorLog "logs/my.iwebshop.com-error.log"

   CustomLog "logs/my.iwebshop.com-access.log" common

   <Directory "F:\www\test">

       Options Indexes FollowSymLinks

       AllowOverride All

       Require all granted

   </Directory>

</VirtualHost>

然后在hosts文件中最下面加上 127.0.0.1  xxx.test.com

重启apache即可
