.htaccess多变量重写

Question

I managed to put together .htaccess like this and it is working fine

RewriteRule ^$ /splash [L,R=301]        
RewriteCond %{HTTP_HOST}  ^example.com
RewriteRule (.*) http://www.examle.com/$1 [R=301,QSA,L]
RewriteRule ^([A-Za-z0-9-]+)?$ /index.php?cat=$1 [L]

This redirects things like example.com/one to http://www.example.com/index.php?cat=one

However, I would like to add more functionality for my current project so that multiple variables get parsed. So for example:

example.com/category-one?another_variable=some_data&even_more=more_data, etc... 

get parsed to

http://www.example.com/index.php?cat=category-one&another_variable=some_data&even_more=more_data

Also, is solution like this seo-friendly?

Answer 1

Add QSA flag in last rule:

RewriteRule ^$ /splash [L,R=301]

RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L,NE]

RewriteRule ^([a-z0-9-]+)/?$ /index.php?cat=$1 [L,NC,QSA]

• QSA (Query String Append) flag preserves existing query parameters while adding a new one.

试试这个RewriteRule ^ mydir /（[0-9] +）/（。*）$ myfile.php？var1 = $ 1＆var2 = $ 2 [NC，L]
