HTTP::Router::Blind
A simple, framework-agnostic HTTP Router for Perl6
Example
With the HTTP::Easy server:
use v6;
use HTTP::Easy::PSGI;
use HTTP::Router::Blind;
my $http = HTTP::Easy::PSGI.new(:port(8080));
my $router = HTTP::Router::Blind.new();
# simple string-match route
$router.get("/", sub (%env) {
[200, ['Content-Type' => 'text/plain'], ["Home is where the heart is"]]
});
$router.get("/about", sub (%env) {
[200, ['Content-Type' => 'text/plain'], ["About this site"]]
});
# string match with keyword params,
# the second parameter to the handler function is a hash of params
# extracted from the URL
$router.get("/user/:id", sub (%env, %params) {
my $user-id = %params<id>;
[200, ['Content-Type' => 'text/plain'], ["It's user $user-id"]]
});
# regex match, with named capture-group,
# will match a request like '/items/42253',
# the second parameter to the handler is the Regex match object;
$router.get(/\/items\/$<id>=(.*)/, sub (%env, $params) {
my $id = $params<id>;
[200, ['Content-Type' => 'text/plain'], ["got request for item $id"]]
});
# you can pass multiple handler functions
# which will be chained together in order
sub do-something-special (%env) { ...; return %env; }
$router.get('/secret', &do-something-special, sub (%env) {
[200, ['Content-Type' => 'text/plain'], ["it's a secret"]]
});
# in our app function, we just call $router.dispatch
my $app = sub (%env) {
$router.dispatch(%env<REQUEST_METHOD>, %env<REQUEST_URI>, %env);
};
$http.handle($app);
CHANGELOG
- 2.0.0 : for keyword and regex matches, pass the matched
params
as a second
parameter to the handler function, instead of setting %env<params>
.
