NAME ^

Dancer::HTTP - helper for rendering HTTP status codes for Dancer

DESCRIPTION ^

Helper for rendering HTTP status codes for Dancer

METHODS ^

status( $status )

Returns the numerical status of $status.

    # all three are equivalent, and will return '405'

    $x = Dancer::HTTP->status( 405 );
    $x = Dancer::HTTP->status( 'Method Not Allowed' );
    $x = Dancer::HTTP->status( 'method_not_allowed' );

codes

Returns a hashref of all HTTP status known to Dancer. The keys are the numerical statuses and the values their string equivalents.

    print Dancer::HTTP->codes->{404}; # prints 'File Not Found'

HTTP CODES ^

The following codes/aliases are understood by any status() call made from a Dancer script. The aliases can be used as-is (e.g., Moved Permanently), or as lower-case string with all non-alphanumerical characters changed to underscores (e.g., moved_permanently).

    get '/user/:user' => sub {
        my $user = find_user( param('user') );

        unless ( $user ) {
            status 404;

            # or could be
            status 'not_found';

            # or even
            status 'Not Found';
        }

        ...
    };
