problem description
because the request is to be rewritten, the old version uses an action parameter in body to execute different code. My plan is to use openResty .
to minimize the problem and restore it, using location
location ~ ^/oldpath/interface.php {
set $target "";
access_by_lua_file /var/www/script.lua;
if ($target != "") { -sharp $target
proxy_pass https://$target;
}
}tested that the $targe variable has indeed been set (verified with the echo output), but there is something wrong with the if judgment, which clearly has a value, but does not execute the fragment in if.
