重写 Apache Query_String

Question

I have a query string URL: http://localhost/cgi-bin/qgis_mapserv.fcgi?map=/home/qgis/project/map.qgs. I want to hind the map.qgs path in the variable MAP. Besides the map variable, there are some variables (version, request, service, etc). Here is what I need:

RewriteRule: Pattern: ^cgi-bin/qgis_mapserv.fcgi?map=map.qgs&(. )$ Substitution: ^cgi-bin/qgis_mapserv.fcgi?map=/home/qgis/project/map.qgs&(. )$

Find bellow my unsuccessful attempt:

RewriteEngine On
RewriteCond %{REQUEST_URI}  ^/cgi-bin/qgis_mapserv.fcgi$
RewriteCond %{QUERY_STRING} ^map=([A-Za-z0-9.-_]+)$
RewriteRule ^cgi-bin/qgis_mapserv.fcgi?(.*)$ cgi-bin/qgis_mapserv.fcgi?$1

Note: The map variable can show up in the pattern uRL anywhere among the other variables.

I wonder what I am missing on the code above

Answer 1

You are almost there. The reason why your rule isn't working is because you can't test queryString in pattern of a RewriteRule.

You need to change your rule's pattern to

  RewriteRule ^cgi-bin/qgis_mapserv.fcgi$

With this change your htaccess rules will look like:

RewriteEngine On
RewriteCond %{REQUEST_URI}  ^/cgi-bin/qgis_mapserv.fcgi$
RewriteCond %{QUERY_STRING} ^map=([A-Za-z0-9./-_]+)/map.qgs$
RewriteRule ^/?cgi-bin/qgis_mapserv.fcgi$ /cgi-bin/qgis_mapserv.fcgi?%1 [R,L]
