=head1 DESCRIPTION
-The Catalyst Request.
+This is the Catalyst Request class, which provides an interface to data for the
+current client request. The request object is prepared by L<Catalyst::Engine>,
+thus hiding the details of the particular engine implementation.
-=head2 METHODS
+=head1 METHODS
-=head3 action
+=head2 $req->action
-Contains the action.
+Returns the requested action as a L<Catalyst::Action> object.
- print $c->request->action;
+=head2 $req->address
-=head3 arguments (args)
+Returns the IP address of the client.
-Returns an arrayref containing the arguments.
+=head2 $req->arguments
+
+Returns a reference to an array containing the arguments.
print $c->request->arguments->[0];
-=head3 base
+For example, if your action was
+
+ package MyApp::C::Foo;
+
+ sub moose : Local {
+ ...
+ }
+
+and the URI for the request was C<http://.../foo/moose/bah>, the string C<bah>
+would be the first and only argument.
+
+=head2 $req->args
+
+Shortcut for arguments.
+
+=head2 $req->base
+
+Contains the URI base. This will always have a trailing slash.
+
+If your application was queried with the URI
+C<http://localhost:3000/some/path> then C<base> is C<http://localhost:3000/>.
+
+=cut
+
+sub base {
+ my ( $self, $base ) = @_;
+
+ return $self->{base} unless $base;
+
+ $self->{base} = $base;
+
+ # set the value in path for backwards-compat
+ if ( $self->uri ) {
+ $self->path;
+ }
+
+ return $self->{base};
+}
+
+=head2 $req->body
+
+Returns the message body of the request, unless Content-Type is
+C<application/x-www-form-urlencoded> or C<multipart/form-data>.
+
+=cut
+
+sub body {
+ my ( $self, $body ) = @_;
+ $self->{_context}->prepare_body;
+ return $self->{_body}->body;
+}
+
+=head2 $req->body_parameters
+
+Returns a reference to a hash containing body (POST) parameters. Values can
+be either a scalar or an arrayref containing scalars.
+
+ print $c->request->body_parameters->{field};
+ print $c->request->body_parameters->{field}->[0];
+
+These are the parameters from the POST part of the request, if any.
+
+=head2 $req->body_params
+
+Shortcut for body_parameters.
+
+=cut
+
+sub body_parameters {
+ my ( $self, $params ) = @_;
+ $self->{_context}->prepare_body;
+ $self->{body_parameters} = $params if $params;
+ return $self->{body_parameters};
+}
+
+=head2 $req->content_encoding
-Contains the uri base.
+Shortcut for $req->headers->content_encoding.
-=head3 cookies
+=head2 $req->content_length
-Returns a hashref containing the cookies.
+Shortcut for $req->headers->content_length.
+
+=head2 $req->content_type
+
+Shortcut for $req->headers->content_type.
+
+=head2 $req->cookie
+
+A convenient method to access $req->cookies.
+
+ $cookie = $c->request->cookie('name');
+ @cookies = $c->request->cookie;
+
+=cut
+
+sub cookie {
+ my $self = shift;
+
+ if ( @_ == 0 ) {
+ return keys %{ $self->cookies };
+ }
+
+ if ( @_ == 1 ) {
+
+ my $name = shift;
+
+ unless ( exists $self->cookies->{$name} ) {
+ return undef;
+ }
+
+ return $self->cookies->{$name};
+ }
+}
+
+=head2 $req->cookies
+
+Returns a reference to a hash containing the cookies.
print $c->request->cookies->{mycookie}->value;
-=head3 headers
+The cookies in the hash are indexed by name, and the values are L<CGI::Cookie>
+objects.
-Returns a L<HTTP::Headers> object containing the headers.
+=head2 $req->header
+
+Shortcut for $req->headers->header.
+
+=head2 $req->headers
+
+Returns an L<HTTP::Headers> object containing the headers for the current request.
print $c->request->headers->header('X-Catalyst');
-=head3 match
+=head2 $req->hostname
+
+Returns the hostname of the client.
+
+=cut
+
+sub hostname {
+ my $self = shift;
+
+ if ( @_ == 0 && not $self->{hostname} ) {
+ $self->{hostname} =
+ gethostbyaddr( inet_aton( $self->address ), AF_INET );
+ }
+
+ if ( @_ == 1 ) {
+ $self->{hostname} = shift;
+ }
+
+ return $self->{hostname};
+}
+
+=head2 $req->input
+
+Alias for $req->body.
+
+=head2 $req->match
+
+This contains the matching part of a Regex action. Otherwise
+it returns the same as 'action', except for default actions,
+which return an empty string.
+
+=head2 $req->method
+
+Contains the request method (C<GET>, C<POST>, C<HEAD>, etc).
-Contains the match.
+=head2 $req->param
- print $c->request->match;
+Returns GET and POST parameters with a CGI.pm-compatible param method. This
+is an alternative method for accessing parameters in $c->req->parameters.
-=head3 parameters (params)
+ $value = $c->request->param( 'foo' );
+ @values = $c->request->param( 'foo' );
+ @params = $c->request->param;
-Returns a hashref containing the parameters.
+Like L<CGI>, and B<unlike> earlier versions of Catalyst, passing multiple
+arguments to this method, like this:
- print $c->request->parameters->{foo};
+ $c->request->param( 'foo', 'bar', 'gorch', 'quxx' );
-=head3 path
+will set the parameter C<foo> to the multiple values C<bar>, C<gorch> and
+C<quxx>. Previously this would have added C<bar> as another value to C<foo>
+(creating it if it didn't exist before), and C<quxx> as another value for
+C<gorch>.
-Contains the path.

+
