Plack::App::URLMap - Map multiple apps in different paths
use Plack::App::URLMap; my $app1 = sub { ... }; my $app2 = sub { ... }; my $app3 = sub { ... }; my $urlmap = Plack::App::URLMap->new; $urlmap->map("/" => $app1); $urlmap->map("/foo" => $app2); $urlmap->map("http://bar.example.com/" => $app3); my $app = $urlmap->to_app;
Plack::App::URLMap is a PSGI application that can dispatch multiple applications based on URL path and hostnames (a.k.a "virtual hosting") and takes care of rewriting SCRIPT_NAME and PATH_INFO. This module is inspired by Rack::URLMap.
SCRIPT_NAME
PATH_INFO
$urlmap->map("/foo" => $app); $urlmap->map("http://bar.example.com/" => $another_app);
Maps URL path or an absolute URL to a PSGI application. The match order is sorted by host name length and then path length.
URL paths need to match from the beginning and should match completely till the path separator (or the end of the path). For example, if you register the path /foo, it will match with the request /foo, /foo/ or /foo/bar but it won't match with /foox.
/foo
/foo/
/foo/bar
/foox
Mapping URL with host names is also possible, and in that case the URL mapping works like a virtual host.
Alias for map.
map
my $handler = $urlmap->to_app;
Returns the PSGI application code reference. Note that the Plack::App::URLMap object is callable (by overloading the code dereference), so returning the object itself as a PSGI application should also work.
You can set the environment variable PLACK_URLMAP_DEBUG to see how this application matches with the incoming request host names and paths.
