package HTTP::Server::Simple::Mason; use base qw/HTTP::Server::Simple::CGI/; use strict; our $VERSION = '0.09'; =head1 NAME HTTP::Server::Simple::Mason - An abstract baseclass for a standalone mason server =head1 SYNOPSIS my $server = MyApp::Server->new(); $server->run; package MyApp::Server; use base qw/HTTP::Server::Simple::Mason/; sub mason_config { return ( comp_root => '/tmp/mason-pages' ); } =head1 DESCRIPTION =head1 INTERFACE See L and the documentation below. =cut use HTML::Mason::CGIHandler; use HTML::Mason::FakeApache; use Hook::LexWrap; wrap 'HTML::Mason::FakeApache::send_http_header', pre => sub { my $r = shift; my $status = $r->header_out('Status') || '200 H::S::Mason OK'; print STDOUT "HTTP/1.0 $status\n"; }; =head2 mason_handler Returns the server's C object. The first time this method is called, it creates a new handler by calling C. =cut sub mason_handler { my $self = shift; $self->{'mason_handler'} ||= $self->new_handler; return $self->{'mason_handler'}; } =head2 handle_request CGI Called with a CGI object. Invokes mason and runs the request =cut sub handle_request { my $self = shift; my $cgi = shift; if ( ( !$self->mason_handler->interp->comp_exists( $cgi->path_info ) ) && ( $self->mason_handler->interp->comp_exists( $cgi->path_info . "/index.html" ) ) ) { $cgi->path_info( $cgi->path_info . "/index.html" ); } eval { my $m = $self->mason_handler; $m->handle_cgi_object($cgi) }; if ($@) { my $error = $@; $self->handle_error($error); } } =head2 handle_error ERROR If the call to C dies, C is called with the exception (that is, C<$@>). By default, it does nothing; it can be overriden by your subclass. =cut sub handle_error { my $self = shift; return; } =head2 new_handler Creates and returns a new C, with configuration specified by the C and C methods. You don't need to call this method yourself; C will automatically call it the first time it is called. =cut sub new_handler { my $self = shift; my $handler_class = $self->handler_class; my $handler = $handler_class->new( $self->default_mason_config, $self->mason_config, # Override mason's default output method so # we can change the binmode to our encoding if # we happen to be handed character data instead # of binary data. # # Cloned from HTML::Mason::CGIHandler out_method => sub { my $m = HTML::Mason::Request->instance; my $r = $m->cgi_request; # Send headers if they have not been sent by us or by user. # We use instance here because if we store $request we get a # circular reference and a big memory leak. unless ($r->http_header_sent) { $r->send_http_header(); } { $r->content_type || $r->content_type('text/html; charset=utf-8'); # Set up a default if ($r->content_type =~ /charset=([\w-]+)$/ ) { my $enc = $1; binmode *STDOUT, ":encoding($enc)"; } # We could perhaps install a new, faster out_method here that # wouldn't have to keep checking whether headers have been # sent and what the $r->method is. That would require # additions to the Request interface, though. print STDOUT grep {defined} @_; } }, @_, ); $self->setup_escapes($handler); return ($handler); } =head2 handler_class Returns the name of the Mason handler class invoked in C. Defaults to L, but in your subclass you may wish to change it to a subclass of L. =cut sub handler_class { "HTML::Mason::CGIHandler" } =head2 setup_escapes $handler Sets up the Mason escapes for the handler C<$handler>. For example, the C in <% $name | h %> By default, sets C to C and C to C, but you can override this in your subclass. =cut sub setup_escapes { my $self = shift; my $handler = shift; $handler->interp->set_escape( h => \&HTTP::Server::Simple::Mason::escape_utf8 ); $handler->interp->set_escape( u => \&HTTP::Server::Simple::Mason::escape_uri ); return; } =head2 mason_config Returns a subclass-defined mason handler configuration; you almost certainly want to override it and specify at least C. =cut sub mason_config { (); # user-defined } =head2 default_mason_config Returns the default mason handler configuration (which can be overridden by entries in C). =cut sub default_mason_config { ( default_escape_flags => 'h', # Turn off static source if we're in developer mode. autoflush => 0 ); } # {{{ escape_utf8 =head2 escape_utf8 SCALARREF does a css-busting but minimalist escaping of whatever html you're passing in. =cut sub escape_utf8 { my $ref = shift; my $val = $$ref; use bytes; $val =~ s/&/&/g; $val =~ s//>/g; $val =~ s/\(/(/g; $val =~ s/\)/)/g; $val =~ s/"/"/g; $val =~ s/'/'/g; $$ref = $val; Encode::_utf8_on($$ref); } # }}} # {{{ escape_uri =head2 escape_uri SCALARREF Escapes URI component according to RFC2396 =cut use Encode qw(); sub escape_uri { my $ref = shift; $$ref = Encode::encode_utf8($$ref); $$ref =~ s/([^a-zA-Z0-9_.!~*'()-])/uc sprintf("%%%02X", ord($1))/eg; Encode::_utf8_on($$ref); } # }}} =head1 CONFIGURATION AND ENVIRONMENT For most configuration, see L. You can (and must) configure your mason CGI handler by subclassing this module and overriding the subroutine C. It's most important that you set a component root (where your pages live) by adding comp_root => '/some/absolute/path' See the Synopsis section or C in the distribution for a complete example. =head1 DEPENDENCIES L L =head1 INCOMPATIBILITIES None reported. =head1 BUGS AND LIMITATIONS Please report any bugs or feature requests to C, or through the web interface at L. =head1 AUTHOR Jesse Vincent C<< >> =head1 LICENCE AND COPYRIGHT Copyright (c) 2001-2005, Jesse Vincent C<< >>.
