DESCRIPTION

This is the Catalyst Request class, which provides a set of accessors to the request data. The request object is prepared by the specialized Catalyst Engine module thus hiding the details of the particular engine implementation.

METHODS

$req->action

Contains the requested action.

print $c->request->action;

$req->address

Contains the remote address.

print $c->request->address

$req->args

Shortcut for arguments

$req->arguments

Returns a reference to an array containing the arguments.

print $c->request->arguments->[0];

For example, if your action was

package MyApp::C::Foo;

sub moose : Local {
	...
}

And the URI for the request was http://.../foo/moose/bah the string bah would be the first and only argument.

$req->base

Contains the URI base. This will always have a trailing slash.

If your application was queried with the URI http://localhost:3000/some/path then base is http://localhost:3000/.

$req->body

Contains the message body of the request unless Content-Type is application/x-www-form-urlencoded or multipart/form-data.

print $c->request->body

$req->body_parameters

Returns a reference to a hash containing body 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.

$req->body_params

An alias for body_parameters.

$req->content_encoding

Shortcut to $req->headers->content_encoding

$req->content_length

Shortcut to $req->headers->content_length

$req->content_type

Shortcut to $req->headers->content_type

$req->cookie

A convenient method to $req->cookies.

$cookie  = $c->request->cookie('name');
@cookies = $c->request->cookie;

$req->cookies

Returns a reference to a hash containing the cookies.

print $c->request->cookies->{mycookie}->value;

The cookies in the hash are indexed by name, and the values are CGI::Cookie objects.

$req->header

Shortcut to $req->headers->header

$req->headers

Returns an HTTP::Headers object containing the headers.

print $c->request->headers->header('X-Catalyst');

$req->hostname

Lookup the current users DNS hostname.

print $c->request->hostname

$req->input

Shortcut for $req->body.

$req->match

This contains the matching part of a regexp action. Otherwise it returns the same as 'action'.

print $c->request->match;

$req->method

Contains the request method (GET, POST, HEAD, etc).

print $c->request->method;

$req->param

Get request parameters with a CGI.pm-compatible param method. This is a method for accessing parameters in $c->req->parameters.

$value  = $c->request->param( 'foo' );
@values = $c->request->param( 'foo' );
@params = $c->request->param;

Like CGI, and unlike previous versions of Catalyst, passing multiple arguments to this method, like this:

$c->request( 'foo', 'bar', 'gorch', 'quxx' );

will set the parameter foo to the multiple values bar, gorch and quxx. Previously this would have added bar as another value to foo (creating it if it didn't exist before), and quxx as another value for gorch.

$req->params

Shortcut for $req->parameters.

$req->parameters

Returns a reference to a hash containing parameters. Values can be either a scalar or an arrayref containing scalars.

print $c->request->parameters->{field};
print $c->request->parameters->{field}->[0];

This is the combination of query_parameters and body_parameters.

$req->path

Contains the path.

print $c->request->path;

$req->path_info

alias for path, added for compability with CGI

$req->protocol

Contains the protocol.

$req->query_parameters

Returns a reference to a hash containing query parameters. Values can be either a scalar or an arrayref containing scalars.

print $c->request->query_parameters->{field};
print $c->request->query_parameters->{field}->[0];

These are the parameters from the query string portion of the request's URI, if any.

$req->read( [$maxlength] )

Read a chunk of data from the request body. This method is designed to be used in a while loop, reading $maxlength bytes on every call. $maxlength defaults to the size of the request if not specified.

You have to set MyApp->config->{parse_on_demand} to use this directly.

$req->referer

Shortcut to $req->headers->referer. Referring page.

$req->secure

Contains a boolean denoting whether the communication is secure.

$req->snippets

Returns a reference to an array containing regex snippets.

my @snippets = @{ $c->request->snippets };

$req->upload

A convenient method to $req->uploads.

$upload  = $c->request->upload('field');
@uploads = $c->request->upload('field');
@fields  = $c->request->upload;

for my $upload ( $c->request->upload('field') ) {
    print $upload->filename;
}

$req->uploads

Returns a reference to a hash containing uploads. Values can be either a hashref or a arrayref containing Catalyst::Request::Upload objects.

my $upload = $c->request->uploads->{field};
my $upload = $c->request->uploads->{field}->[0];

$req->uri

Returns a URI object for the request.

$req->user

Returns the user.

$req->user_agent

Shortcut to $req->headers->user_agent. User Agent version string.
