Windows 10中的xampp Vhosts无法正常工作

I have win 10 and i have installed xammp and i want to setup a virtual host

i have hosts file edited like that

# localhost name resolution is handled within DNS itself.
127.0.0.1       localhost
::1             localhost
127.0.0.1       unii

and i have the httpd-vhosts.conf like that

Listen 80 <VirtualHost 127.0.0.1:80>
DocumentRoot "C:/xampp/htdocs/unii/public"
ServerName "unii"
</VirtualHost>

the Vhost redirect to the root of htdoc act like "localhost"

what is missed ??
