Apache RewriteRule模式不起作用

Question

I wanna rewrite rule in order to allow ability the path like this:

http://example.com/api/somemethod/ Api is an api.php file that contains api class.

I've rewritten rules in .htaccess, but if i try to link above, i got an error:

Object not found! The requested URL was not found on this server. If
you entered the URL manually please check your spelling and try again.
If you think this is a server error, please contact the webmaster.
Error 404

Here is my .htaccess file:

RewriteEngine On

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

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

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

Answer 1

Since I can't yet comment on the question (yay karma), I will post one of the more common answers, as this is usually caused by the .htaccess file not being read/followed:

"try putting junk in your htaccess file. If it's being read, you will get an Internal Server Error when accessing that resource. If it doesn't cause an Internal Server Error, see AllowOverride. This won't work from 2.4 if AllowOverride is used with Nonfatal"
