=head1 DESCRIPTION
=head1 METHODS
-=over 4
-
-=item $req->action
+=head2 $req->action
-Returns the requested action as a L<Catalyst::Action> object.
+[DEPRECATED] Returns the name of the requested action.
-=cut
-sub action { shift->{_context}->action(@_) }
+Use C<< $c->action >> instead (which returns a
+L<Catalyst::Action|Catalyst::Action> object).
-=item $req->address
+=head2 $req->address
Returns the IP address of the client.
-=item $req->arguments
+=head2 $req->arguments
Returns a reference to an array containing the arguments.
For example, if your action was
- package MyApp::C::Foo;
-
- sub moose : Local {
- ...
- }
+ 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.
-=item $req->args
+=head2 $req->args
Shortcut for arguments.
-=item $req->base
+=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};
-}
-
-=item $req->body
+=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;
-}
-
-=item $req->body_parameters
+=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.
These are the parameters from the POST part of the request, if any.
-=item $req->body_params
+=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};
-}
-
-=item $req->content_encoding
+=head2 $req->content_encoding
Shortcut for $req->headers->content_encoding.
-=item $req->content_length
+=head2 $req->content_length
Shortcut for $req->headers->content_length.
-=item $req->content_type
+=head2 $req->content_type
Shortcut for $req->headers->content_type.
-=item $req->cookie
+=head2 $req->cookie
A convenient method to access $req->cookies.
}
}
-=item $req->cookies
+=head2 $req->cookies
Returns a reference to a hash containing the cookies.
The cookies in the hash are indexed by name, and the values are L<CGI::Cookie>
objects.
-=item $req->header
+=head2 $req->header
Shortcut for $req->headers->header.
-=item $req->headers
+=head2 $req->headers
Returns an L<HTTP::Headers> object containing the headers for the current request.
print $c->request->headers->header('X-Catalyst');
-=item $req->hostname
+=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 );
- }
+=head2 $req->input
- if ( @_ == 1 ) {
- $self->{hostname} = shift;
- }
+Alias for $req->body.
- return $self->{hostname};
-}
+=head2 $req->query_keywords
-=item $req->input
+Contains the keywords portion of a query string, when no '=' signs are
+present.
-Alias for $req->body.
+ http://localhost/path?some+keywords
+
+ $c->request->query_keywords will contain 'some keywords'
-=item $req->match
+=head2 $req->match
This contains the matching part of a Regex action. Otherwise
-it returns the same as 'action'.
+it returns the same as 'action', except for default actions,
+which return an empty string.
-=item $req->method
+=head2 $req->method
Contains the request method (C<GET>, C<POST>, C<HEAD>, etc).
-=item $req->param
+=head2 $req->param
Returns GET and POST parameters with a CGI.pm-compatible param method. This
is an alternative method for accessing parameters in $c->req->parameters.
Like L<CGI>, and B<unlike> earlier versions of Catalyst, passing multiple
arguments to this method, like this:
- $c->request->param( 'foo', 'bar', 'gorch', 'quxx' );
+ $c->request->param( 'foo', 'bar', 'gorch', 'quxx' );
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>
}
}
-=item $req->parameters
+=head2 $req->parameters
Returns a reference to a hash containing GET and POST parameters. Values can
be either a scalar or an arrayref containing scalars.
This is the combination of C<query_parameters> and C<body_parameters>.
-=item $req->params
+=head2 $req->params
Shortcut for $req->parameters.

-
-=item $req->path
+=head2 $req->path
Returns the path, i.e. the part of the URI after $req->base, for the current request.
-=item $req->path_info
+=head2 $req->path_info
Alias for path, added for compability with L<CGI>.
=cut
