Nginx URL重写为2个不同的CMS

I'm using Joomla/MariaDB and another CMS/PostgreSQL in the same server with Nginx as web server. The rewriting rules for joomla works as well, but doesn't work for the other one. The URL's structures from the PostgreSQL CMS looks like this:

http://example.com/dir/Something.php?somename=Blah_Setup/Otherstring.php
http://example.com/dir/Something.php?somename=Blah_Setup/Otherstring.php&new_blah=true
http://example.com/dir/Something.php?somename=Blah_Setup/Otherstring.php&include=General_Info&worker_id=new

This is what I have:

location /sis/ {
     rewrite ^(/sis)/Modules.php?modname=(.*/)\..*$ $1/$2  last;
}

Can anyone point out where I'm going wrong, please?

There are two problems with your rewrite rule:

• The location /sis/ does not process URIs ending with .php, so they will never see your rewrite rule
• The query string (from the ? onwards) is not considered as part of the rewrite pattern

You can easily extract the value of the modname parameter by using the predefined variable $arg_modname.

If all of the /sys/Modules.php URLs need to be rewritten, the solution is easily accomplished with an exact match location:

location = /sis/Modules.php {
    rewrite ^ /sis/$arg_modname last;
}

If only those URIs with an $arg_modname require a rewrite, you will need to wrap it inside an if ($arg_modname) { ... } block. But it does increase complexity so a simple example is more difficult to provide without seeing your entire server configuration.
