apache - htaccess 表达式无法正常工作

Question

仅当主机名等于“dev.local”时，我才尝试设置 RewriteBase，但我的 if 语句似乎不起作用。

虚拟主机：

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    ServerName dev.local
    DocumentRoot /var/www-shared

    Alias /frontoffice /var/www-shared/frontoffice-laravel/public

    <Directory /var/www-shared>
        Options -Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

访问：

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On
    <If "%{SERVER_NAME} == 'dev.local'">
        RewriteBase /frontoffice
    </If>

    # Redirect Trailing Slashes...
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>
