使用RewriteRule进行重定向，将密钥重定向到新的URL

Question

I got this url:

somesite.org/news.php?a=0&b=20

What I want - redirect it to

somesite.org/specialnews/20

If you see - key a means the type. So a=0 means specialnews. So I need redirect only those urls, that have a=0 and base url ( news.php ) also to /specialnews/ .

What I've tried is:

RewriteCond %{QUERY_STRING} ^a=0&b=(.*)$ 
RewriteRule ^news\.php\?a\=0&b\=(.*)$ specialnews/$2 [R=301]

didn't help ;) Need directions.

Answer 1

You can't match query string params in RewriteRule, but you can capture paramters via RewriteCond and use it (with %) in RewriteRule:

RewriteCond %{QUERY_STRING} a=0&b=(.*)
RewriteRule ^news.php /specialnews/%1? [R=301]
