由于htaccess而难以访问子目录文件

This is my .htaccess code

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-s
    RewriteRule ^(.*)$ api.php?rquest=$1 [QSA,NC,L]

    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^(.*)$ api.php [QSA,NC,L]

    RewriteCond %{REQUEST_FILENAME} -s
    RewriteRule ^(.*)$ api.php [QSA,NC,L]

    RewriteCond %{REQUEST_URI} !^/images/   

</IfModule>

My directory structure:

My problem is that I can access my api.php by calling /users or /getData etc. But if I go for images/someImage.jpg then it not allowing.

Try this simple rewrite rule

RewriteBase /your web directory

RewriteEngine On

RewriteRule ^([a-zA-Z0-9_-]+)$ api.php?rquest=$1

RewriteRule ^([a-zA-Z0-9_-]+)/$ api.php?rquest=$1

the following is the break down of the code

RewriteBase / #enter your directory root here

RewriteEngine On

the following rewrite rule will redirect for example www.example.com/home to example.com/api.php?rquest=$1

RewriteRule ^([a-zA-Z0-9_-]+)$ api.php?rquest=$1

and the following will redirect for example www.example/home/ to example.com/api.php?rquest=$1. notice the / after /home

RewriteRule ^([a-zA-Z0-9_-]+)/$ api.php?rquest=$1

the above lines of code excludes the rule to redirect www.example.com/images/someimages.jpg to www.example.com/

So this will work for now.
