.htaccess rewrite wildcard subsubdomain and params

问题

I'm trying to write a mod_rewrite to work like this

• wildcard.subdomain.domain.com => subdomain.domain.com/data.php?q=wildcard
• wildcard.subdomain.domain.com/?repeat=1 => subdomain.domain.com/data.php?q=wildcard&repeat=1
• subdomain.domain.com => data.php
• www.subdomain.domain.com => data.php

What I've done so far in my .htaccess

<IfModule mod_rewrite.c>
  Options +FollowSymlinks
  RewriteEngine On
  RewriteCond %{HTTP_HOST} ^([^.]+)\.abc\.def\.com\.br$ [NC]
  RewriteCond %1 !^(www)$ [NC]
  RewriteRule ^.*$ data.php?q=%1 
</IfModule>`

回答1:

Try these:

  # This should cover the first 2 cases
  RewriteCond %{HTTP_HOST} ^([^.]+)\.abc\.def\.com\.br$ [NC]
  RewriteCond %1 !^(www)$ [NC]
  RewriteRule ^$ /data.php?q=%1&%{QUERY_STRING} [L,QSA]

  # This should cover the last 2
  RewriteCond %{HTTP_HOST} ^([^.]+)\.abc\.def\.com\.br$ [NC]
  RewriteCond %1 ^(www)$ [NC]
  RewriteRule ^$ /data.php?%{QUERY_STRING} [L,QSA]

Note that this does nothing in the cases where the request is: wildcard.subdomain.domain.com/some/path/to/file.html These only match request URI's that are /.

For repeat parameter use

RewriteRule ^.*$ data.php?q=%1&%{QUERY_STRING}

if you are using a cpanel , you can create a * sub domain (*.domain.com) and connect it to a directory , then create a index.php in that directory :

<?php
echo "<pre>";
print_r($_SERVER);
echo "</pre>";
?>

test the result , you can export sub domain names from server name or server host
