php到htaccess重写-如果没有$ _POST数据则重定向

Question

if( count( $_POST ) < 1 ) {
    // determine if this was a secure request - we use a non standard HTTPS port so the SERVER_HTTPS_PORT define should always be used in place of 443
    $protocol = $_SERVER['SERVER_PORT'] == SERVER_HTTPS_PORT ? 'https' : 'http';
    header( "HTTP/1.0 301 Moved Permanently" ); 
    header( "Status: 301" ); // this is for chrome compliance
    header( "Location: $protocol://".CLIENT_DOMAIN."{$_SERVER['REQUEST_URI']}" );       
    session_write_close();
    exit;
}

Can this functionality be rewritten with .htaccess rules?

Logic:

If not a POST request, redirect to equivalent page with whole query string by issuing 301 header and status, whilst maintaining protocol.

Answer 1

Try this:

RewriteCond %{REQUEST_METHOD} !=POST
RewriteCond %{SERVER_PORT}s ^443(s)|.*
RewriteRule ^foo/bar$ http%1://www.example.com%{REQUEST_URI} [L,R=301]

Not you just need to replace 443 by your SERVER_HTTPS_PORT value and www.example.com by your CLIENT_DOMAIN value.

Answer 2

This should work for you (replace www.google.com with your CLIENT_DOMAIN ).

RewriteEngine on
RewriteCond %{SERVER_PORT} ^80$
RewriteCond %{REQUEST_METHOD} !^POST$ [NC]
RewriteRule ^(.*)$ http://www.google.com/$1 [L,QSA,R=301]
RewriteCond %{SERVER_PORT} ^443$
RewriteCond %{REQUEST_METHOD} !^POST$ [NC]
RewriteRule ^(.*)$ https://www.google.com/$1 [L,QSA,R=301]

Answer 3

Lookink at the documentation of Apache's mod_rewrite , there might be a way, using %{REQUEST_METHOD} in a RewriteCond condition ; something like this might do the trick :

RewriteCond %{REQUEST_METHOD} !=POST

Followed, of course, by the needed RewriteRule to redirect everything to the non-POST page.

I have no way of testing right now, so this might not be perfect, but something like this could maybe do the trick -- or, at least, guide you to the solution :

RewriteRule ^(.*)$ $1 [QSA,R=301,L]

The idea beeing to

• match everything
• redirect to what was matched
• keeping the Query String (QSA flag)
• and redirecting with a 301 code
• and stopping there
