33 Catalyst::Request - provides information about the current client request
44 $req->body_parameters;

65 $req->captures; # previously knows as snippets
72 See also L<Catalyst>, L<Catalyst::Request::Upload>.
76 This is the Catalyst Request class, which provides an interface to data for the
77 current client request. The request object is prepared by L<Catalyst::Engine>,
78 thus hiding the details of the particular engine implementation.
84 [DEPRECATED] Returns the name of the requested action.
87 Use C<< $c->action >> instead (which returns a
88 L<Catalyst::Action|Catalyst::Action> object).
92 Returns the IP address of the client.
94 =head2 $req->arguments
96 Returns a reference to an array containing the arguments.
98 print $c->request->arguments->[0];
100 For example, if your action was
102 package MyApp::C::Foo;
108 and the URI for the request was C<http://.../foo/moose/bah>, the string C<bah>
109 would be the first and only argument.
113 Shortcut for arguments.
117 Contains the URI base. This will always have a trailing slash.
119 If your application was queried with the URI
120 C<http://localhost:3000/some/path> then C<base> is C<http://localhost:3000/>.
125 my ( $self, $base ) = @_;
127 return $self->{base} unless $base;
129 $self->{base} = $base;
131 # set the value in path for backwards-compat
136 return $self->{base};
141 Returns the message body of the request, unless Content-Type is
142 C<application/x-www-form-urlencoded> or C<multipart/form-data>.
148 $self->{_context}->prepare_body;
150 return unless $self->{_body};
152 return $self->{_body}->body;
155 =head2 $req->body_parameters
157 Returns a reference to a hash containing body (POST) parameters. Values can
158 be either a scalar or an arrayref containing scalars.
160 print $c->request->body_parameters->{field};
161 print $c->request->body_parameters->{field}->[0];
163 These are the parameters from the POST part of the request, if any.
165 =head2 $req->body_params
167 Shortcut for body_parameters.
171 sub body_parameters {
172 my ( $self, $params ) = @_;
173 $self->{_context}->prepare_body;
174 $self->{body_parameters} = $params if $params;
175 return $self->{body_parameters};
178 =head2 $req->content_encoding
180 Shortcut for $req->headers->content_encoding.
182 =head2 $req->content_length
184 Shortcut for $req->headers->content_length.
186 =head2 $req->content_type
188 Shortcut for $req->headers->content_type.
192 A convenient method to access $req->cookies.
194 $cookie = $c->request->cookie('name');
195 @cookies = $c->request->cookie;
203 return keys %{ $self->cookies };
210 unless ( exists $self->cookies->{$name} ) {
214 return $self->cookies->{$name};
220 Returns a reference to a hash containing the cookies.
222 print $c->request->cookies->{mycookie}->value;
224 The cookies in the hash are indexed by name, and the values are L<CGI::Cookie>
229 Shortcut for $req->headers->header.
233 Returns an L<HTTP::Headers> object containing the headers for the current request.
235 print $c->request->headers->header('X-Catalyst');
237 =head2 $req->hostname
239 Returns the hostname of the client.
246 if ( @_ == 0 && not $self->{hostname} ) {
248 gethostbyaddr( inet_aton( $self->address ), AF_INET );
252 $self->{hostname} = shift;
255 return $self->{hostname};
260 Alias for $req->body.
264 This contains the matching part of a Regex action. Otherwise
265 it returns the same as 'action', except for default actions,
266 which return an empty string.
270 Contains the request method (C<GET>, C<POST>, C<HEAD>, etc).
274 Returns GET and POST parameters with a CGI.pm-compatible param method. This
275 is an alternative method for accessing parameters in $c->req->parameters.
277 $value = $c->request->param( 'foo' );
278 @values = $c->request->param( 'foo' );
279 @params = $c->request->param;
281 Like L<CGI>, and B<unlike> earlier versions of Catalyst, passing multiple
282 arguments to this method, like this:
284 $c->request->param( 'foo', 'bar', 'gorch', 'quxx' );
286 will set the parameter C<foo> to the multiple values C<bar>, C<gorch> and
287 C<quxx>. Previously this would have added C<bar> as another value to C<foo>
288 (creating it if it didn't exist before), and C<quxx> as another value for
297 return keys %{ $self->parameters };

325 =head2 $req->parameters
327 Returns a reference to a hash containing GET and POST parameters. Values can
328 be either a scalar or an arrayref containing scalars.
330 print $c->request->parameters->{field};
331 print $c->request->parameters->{field}->[0];
333 This is the combination of C<query_parameters> and C<body_parameters>.
337 Shortcut for $req->parameters.
342 my ( $self, $params ) = @_;
343 $self->{_context}->prepare_body;
346 $self->{parameters} = $params;
349 $self->{_context}->log->warn(
350 "Attempt to retrieve '$params' with req->params(), " .
351 "you probably meant to call req->param('$params')" );
354 return $self->{parameters};
359 Returns the path, i.e. the part of the URI after $req->base, for the current request.
361 =head2 $req->path_info
363 Alias for path, added for compability with L<CGI>.
368 my ( $self, @params ) = @_;
371 $self->uri->path(@params);
374 elsif ( defined( my $path = $self->{path} ) ) {
378 my $path = $self->uri->path;

380 $path =~ s/^(\Q$location\E)?//;
382 $self->{path} = $path;
388 =head2 $req->protocol
390 Returns the protocol (HTTP/1.0 or HTTP/1.1) used for the current request.
392 =head2 $req->query_parameters
394 Returns a reference to a hash containing query string (GET) parameters. Values can
395 be either a scalar or an arrayref containing scalars.
397 print $c->request->query_parameters->{field};
398 print $c->request->query_parameters->{field}->[0];
400 =head2 $req->read( [$maxlength] )
402 Reads a chunk of data from the request body. This method is intended to be
403 used in a while loop, reading $maxlength bytes on every call. $maxlength
404 defaults to the size of the request if not specified.
406 You have to set MyApp->config->{parse_on_demand} to use this directly.
410 sub read { shift->{_context}->read(@_); }
414 Shortcut for $req->headers->referer. Returns the referring page.
418 Returns true or false, indicating whether the connection is secure (https).
420 =head2 $req->captures
422 Returns a reference to an array containing regex captures.
424 my @captures = @{ $c->request->captures };
426 =head2 $req->snippets
428 C<captures> used to be called snippets. This is still available for backwoards
429 compatibility, but is considered deprecated.
433 A convenient method to access $req->uploads.
435 $upload = $c->request->upload('field');
436 @uploads = $c->request->upload('field');
437 @fields = $c->request->upload;
439 for my $upload ( $c->request->upload('field') ) {

478 $_ = [$_] unless ref($_) eq "ARRAY";
479 push( @$_, $upload );
483 $self->uploads->{$field} = $upload;
491 Returns a reference to a hash containing uploads. Values can be either a
492 L<Catalyst::Request::Upload> object, or an arrayref of
493 L<Catalyst::Request::Upload> objects.
495 my $upload = $c->request->uploads->{field};

509 Returns a URI object for the current request. Stringifies to the URI text.
511 =head2 $req->uri_with( { key => 'value' } );
513 Returns a rewritten URI object for the current request. Key/value pairs
514 passed in will override existing parameters. Unmodified pairs will be
520 my( $self, $args ) = @_;
522 carp( 'No arguments passed to uri_with()' ) unless $args;
524 for my $value ( values %$args ) {

532 my $uri = $self->uri->clone;
535 %{ $uri->query_form_hash },
543 Returns the currently logged in user. Deprecated. The method recommended for
544 newer plugins is $c->user.
546 =head2 $req->user_agent
548 Shortcut to $req->headers->user_agent. Returns the user agent (browser)
