.htaccess重写规则在它是目录时发生

With htaccess I look which page should be loaded and then I get the HTML document for that page.

The problem I have now, there is a directory called api and when this is called the rewrite should not take place, but it does.

My .htaccess file

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ([a-zA-Z0-9])\w+ index.php?page=$0 [QSA,NC]
    RewriteRule ^([^/]+)/([0-9]+)$ index.php?page=$1&id=$2 [QSA,NC,L]
</IfModule>

Can somebody tell me what I am doing wrong?

Fixed with the following condition

RewriteCond %{REQUEST_URI} !^/api/
