url redirection working incorrect using .htacess in php

问题

I have one sub domain api.example.com.

my code is on /var/www/html/ folder.

my all sub domain is redirect to /var/www/html folder.

I am use api.example.com to redirect on /var/www/html/api folder. Using .htaccess

RewriteEngine On

RewriteCond %{HTTP_HOST} ^api\. [NC]
RewriteRule !^api/ api%{REQUEST_URI} [L,NC]

But the problem is, it is also change my url , api.example.com/api i don't want to change my URL.

when i type api.example.com in browser tab and press enter then it is change into the api.example.com/api and it is open index file of api folder but i don't want to change my URL and it will open index file of api folder.

回答1:

Change it to this

RewriteEngine On

RewriteCond %{HTTP_HOST} ^api\.example\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/?api(/.*)?$ [NC]
RewriteRule ^/?(.*)/?$ /api/$1 [L,NC]

Notice

Delete you Browser Cache before you test. If this still so not what you want, than you have somwere some other rule in place.
