=head1 NAME
Dancer2::Plugin::HTTP::Bundle - The missing HTTP bits of Dancer2 Bundled
=head1 VERSION
Version 0.02
=cut
our $VERSION = '0.02';
=head1 SYNOPSIS
There are a few Dancer2 Plugins to help building REST api's. This wrapper helps
loading them all at once, in the right order and will demonstrate the combined
use of them.
use Dancer2::Plugin::HTTP::Bundle
get '/secrets/:id' => http_auth_handler_can('find_something') => sub {
my $secret_object = http_auth_handler->find_something(param->{id})
or return sub { status (404 ) };
http_conditional (
etag => $secret_object->etag,
last_modified => $secret_object->date_last_modified
) =>sub { http_choose_accept (
'application/json' => sub { to_json $secret_object },
'application/xml' => sub { to_xml $secret_object },
{ default => undef }
) }
};
Or a little more verbose
use Dancer2::Plugin::HTTP:::Bundle
get '/secrets/:id' => http_auth_handler_can('find_something') => sub {
# what content-type does the client want
http_choose_accept (
[ 'application/json', 'application/xml' ] => sub {
# find the resource
my $secret_object =
http_auth_handler->find_something(param->{id});
unless ( $secret_object ) {
status (404); # Not Found
return;
}
# set caching information
http_cache_max_age 3600;
http_cache_private;
# make the request conditional
# maybe we do not need to serialize
http_conditional (
etag => $secret_object->etag,
last_modified => $secret_object->date_last_modified
) => sub {
for (http_accept) {
when ('application/json') {
return to_json ( $secret_object )
}
when ('application/xml') {
return to_xml ( $secret_object )
}
}
}
},
[ 'image/png', 'image/jpeg' ] => sub {
...
},
{ default => undef }
)
};
=head1 HTTP... and the RFC's
=item RFC 7234 - Hypertext Transfer Protocol (HTTP/1.1): Caching
The Hypertext Transfer Protocol (HTTP) is a stateless application-
level protocol for distributed, collaborative, hypertext information
systems. This document defines HTTP caches and the associated header
fields that control cache behavior or indicate cacheable response
messages.
