NAME

Router::Simple - simple HTTP router

SYNOPSIS

    use Router::Simple;
    my $router = Router::Simple->new();
    $router->connect('/', {controller => 'Root', action => 'show'});
    $router->connect('/blog/{year}/{month}', {controller => 'Blog', action => 'monthly'});
    my $app = sub {
        my $env = shift;
        if (my $p = $router->match($env)) {
            # $p = { controller => 'Blog', action => 'monthly', ... }
        } else {
            [404, [], ['not found']];
        }
    };

DESCRIPTION

Router::Simple is a simple router class.

Its main purpose is to serve as a dispatcher for web applications.

Router::Simple can match against PSGI $env directly, which means it's easy to use with PSGI supporting web frameworks.

HOW TO WRITE A ROUTING RULE

    $router->connect( '/foo', { controller => 'Root', action => 'foo' } );

    $router->connect( '/wiki/:page', { controller => 'WikiPage', action => 'show' } );
    ...
    $router->match('/wiki/john');
    # => {controller => 'WikiPage', action => 'show', page => 'john' }

    $router->connect( '/download/*.*', { controller => 'Download', action => 'file' } );
    ...
    $router->match('/download/path/to/file.xml');
    # => {controller => 'Download', action => 'file', splat => ['path/to/file', 'xml'] }

    $router->connect( '/blog/{year}', { controller => 'Blog', action => 'yearly' } );
    ...
    $router->match('/blog/2010');
    # => {controller => 'Blog', action => 'yearly', year => 2010 }

    $router->connect( '/blog/{year:[0-9]+}/{month:[0-9]{2}}', { controller => 'Blog', action => 'monthly' } );
    ...
    $router->match('/blog/2010/04');
    # => {controller => 'Blog', action => 'monthly', year => 2010, month => '04' }

    $router->connect( qr{/blog/(\d+)/([0-9]{2})', { controller => 'Blog', action => 'monthly' } );
    ...
    $router->match('/blog/2010/04');
    # => {controller => 'Blog', action => 'monthly', splat => [2010, '04'] }

METHODS

my $router = Router::Simple->new();

Creates a new instance of Router::Simple.

$router->method_not_allowed() : Boolean

This method returns last "$router->match()" call is rejected by HTTP method or not.

$router->connect([$name, ] $pattern, \%destination[, \%options])

Adds a new rule to $router.

    $router->connect( '/', { controller => 'Root', action => 'index' } );
    $router->connect( 'show_entry', '/blog/:id',
        { controller => 'Blog', action => 'show' } );
    $router->connect( '/blog/:id', { controller => 'Blog', action => 'show' } );
    $router->connect( '/comment', { controller => 'Comment', action => 'new_comment' }, {method => 'POST'} );
    

"\%destination" will be used by match method.

You can specify some optional things to "\%options". The current version supports 'method', 'host', and 'on_match'.

"$router->submapper($path, [\%dest, [\%opt]])"

    $router->submapper('/entry/', {controller => 'Entry'})
    

This method is shorthand for creating new instance of Router::Simple::Submapper.

The arguments will be passed to "Router::Simple::SubMapper->new(%args)".

"$match = $router->match($env|$path)"

Matches a URL against one of the contained routes.

The parameter is either a PSGI $env or a plain string that represents a path.

This method returns a plain hashref that would look like:

    {
        controller => 'Blog',
        action     => 'daily',
        year => 2010, month => '03', day => '04',
    }
    

It returns undef if no valid match is found.

"my ($match, $route) = $router->routematch($env|$path);"

Match a URL against one of the routes contained.

Will return undef if no valid match is found, otherwise a result hashref and a Router::Simple::Route object is returned.

"$router->as_string()"

Dumps $router as string.

Example output:

    home         GET  /
    blog_monthly GET  /blog/{year}/{month}
                 GET  /blog/{year:\d{1,4}}/{month:\d{2}}/{day:\d\d}
                 POST /comment
                 GET  /

SEE ALSO

Router::Simple is inspired by routes.py <http://routes.groovie.org/>.

Path::Dispatcher is similar, but so complex.

Path::Router is heavy. It depends on Moose.

HTTP::Router has many dependencies. It is not well documented.

HTTPx::Dispatcher is my old one. It does not provide an OO-ish interface.
