.htaccess-重写规则中的匹配环境变量

Question

I am trying to match the words 'blogs' and 'news' in the following url according to the detected language via htaccess .

the url:

http://localhost/es/noticias

the language detection (working):

RewriteCond %{HTTP_HOST} ^(es)\. [OR]
RewriteCond %{REQUEST_URI} .*/(es)/.*
RewriteRule ^(.*) - [E=LANG:%1,E=NEWS:noticias,E=BLOGS:blogs]

the rule (not matching ENV:BLOGS nor ENV:NEWS)

RewriteRule ^([^\/]+/)?(%{ENV:BLOGS}|%{ENV:NEWS}) index.php?vd=%{ENV:LANG}/$1&m=$2 [NC,QSA,L]

How to match Env Variables in Rewrite Rule ?

EDIT 1 - the extended language translation

RewriteCond %{HTTP_HOST} ^(es)\. [OR]
RewriteCond %{REQUEST_URI} .*/(es)/.*
RewriteRule ^(.*) - [E=LANG:%1,E=NEWS:noticias,E=BLOGS:blogs]

RewriteCond %{HTTP_HOST} ^(en)\. [OR]
RewriteCond %{REQUEST_URI} .*/(en)/.*
RewriteRule ^(.*) - [E=LANG:%1,E=NEWS:news,E=BLOGS:blogs]

RewriteCond %{HTTP_HOST} ^(fr)\. [OR]
RewriteCond %{REQUEST_URI} .*/(fr)/.*
RewriteRule ^(.*) - [E=LANG:%1,E=NEWS:nouvelles,E=BLOGS:blogosphere]

Answer 1

Rather than RewriteRule you need to use RewriteCond for matching env variables. See this code snippet:

RewriteCond %{ENV:BLOGS} ^blogs$ [OR]
RewriteCond %{ENV:NEWS} ^noticias$
# some RewriteRule here
RewriteRule ^ - [L]

RewriteRule on the other hand is used for matching request URI only.
