Apache通过rewrite实现，url后追加“/”

由于apache对未以"/"结尾的url视为资源，故需对url进行加"/"处理

LoadModule rewrite_module modules/mod_rewrite.so

<Directory />

RewriteEngine on

RewriteCond %{REQUEST_URI} .*[^//]$

RewriteRule .*/htdocs/(.+)$ $1/ [L,R=301]

Options FollowSymLinks

AllowOverride All

Order allow,deny

Allow from all

</Directory>     //解决不以"/"结尾请求问题
