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>.
147 my ( $self, $body ) = @_;
148 $self->{_context}->prepare_body;
150 return unless $self->{_body};
152 $self->{_body}->body($body) if $body;
153 return $self->{_body}->body;
156 =head2 $req->body_parameters
158 Returns a reference to a hash containing body (POST) parameters. Values can
159 be either a scalar or an arrayref containing scalars.
161 print $c->request->body_parameters->{field};
162 print $c->request->body_parameters->{field}->[0];
164 These are the parameters from the POST part of the request, if any.
166 =head2 $req->body_params
168 Shortcut for body_parameters.
172 sub body_parameters {
173 my ( $self, $params ) = @_;
174 $self->{_context}->prepare_body;
175 $self->{body_parameters} = $params if $params;
176 return $self->{body_parameters};
179 =head2 $req->content_encoding
181 Shortcut for $req->headers->content_encoding.
183 =head2 $req->content_length
185 Shortcut for $req->headers->content_length.
187 =head2 $req->content_type
189 Shortcut for $req->headers->content_type.
193 A convenient method to access $req->cookies.
195 $cookie = $c->request->cookie('name');
196 @cookies = $c->request->cookie;
204 return keys %{ $self->cookies };
211 unless ( exists $self->cookies->{$name} ) {
215 return $self->cookies->{$name};
221 Returns a reference to a hash containing the cookies.
223 print $c->request->cookies->{mycookie}->value;
225 The cookies in the hash are indexed by name, and the values are L<CGI::Cookie>
230 Shortcut for $req->headers->header.
234 Returns an L<HTTP::Headers> object containing the headers for the current request.
236 print $c->request->headers->header('X-Catalyst');
238 =head2 $req->hostname
240 Returns the hostname of the client.
247 if ( @_ == 0 && not $self->{hostname} ) {
249 gethostbyaddr( inet_aton( $self->address ), AF_INET );
253 $self->{hostname} = shift;
256 return $self->{hostname};
261 Alias for $req->body.
265 This contains the matching part of a Regex action. Otherwise
266 it returns the same as 'action', except for default actions,
267 which return an empty string.
271 Contains the request method (C<GET>, C<POST>, C<HEAD>, etc).
275 Returns GET and POST parameters with a CGI.pm-compatible param method. This
276 is an alternative method for accessing parameters in $c->req->parameters.
278 $value = $c->request->param( 'foo' );
279 @values = $c->request->param( 'foo' );
280 @params = $c->request->param;
282 Like L<CGI>, and B<unlike> earlier versions of Catalyst, passing multiple
283 arguments to this method, like this:
285 $c->request->param( 'foo', 'bar', 'gorch', 'quxx' );
287 will set the parameter C<foo> to the multiple values C<bar>, C<gorch> and
288 C<quxx>. Previously this would have added C<bar> as another value to C<foo>
289 (creating it if it didn't exist before), and C<quxx> as another value for
298 return keys %{ $self->parameters };

326 =head2 $req->parameters
328 Returns a reference to a hash containing GET and POST parameters. Values can
329 be either a scalar or an arrayref containing scalars.
331 print $c->request->parameters->{field};
332 print $c->request->parameters->{field}->[0];
334 This is the combination of C<query_parameters> and C<body_parameters>.
338 Shortcut for $req->parameters.
343 my ( $self, $params ) = @_;
344 $self->{_context}->prepare_body;

350 $self->{_context}->log->warn(
351 "Attempt to retrieve '$params' with req->params(), " .
352 "you probably meant to call req->param('$params')" );
355 return $self->{parameters};
360 Returns the path, i.e. the part of the URI after $req->base, for the current request.
362 =head2 $req->path_info
364 Alias for path, added for compability with L<CGI>.
369 my ( $self, $params ) = @_;
372 $self->uri->path($params);
375 return $self->{path} if $self->{path};
378 my $path = $self->uri->path;
379 my $location = $self->base->path;
380 $path =~ s/^(\Q$location\E)?//;
382 $self->{path} = $path;
387 =head2 $req->protocol
389 Returns the protocol (HTTP/1.0 or HTTP/1.1) used for the current request.
391 =head2 $req->query_parameters
393 Returns a reference to a hash containing query string (GET) parameters. Values can
394 be either a scalar or an arrayref containing scalars.
396 print $c->request->query_parameters->{field};
397 print $c->request->query_parameters->{field}->[0];
399 =head2 $req->read( [$maxlength] )
401 Reads a chunk of data from the request body. This method is intended to be
402 used in a while loop, reading $maxlength bytes on every call. $maxlength
403 defaults to the size of the request if not specified.
405 You have to set MyApp->config->{parse_on_demand} to use this directly.
409 sub read { shift->{_context}->read(@_); }
413 Shortcut for $req->headers->referer. Returns the referring page.
417 Returns true or false, indicating whether the connection is secure (https).
419 =head2 $req->captures
421 Returns a reference to an array containing regex captures.
423 my @captures = @{ $c->request->captures };
425 =head2 $req->snippets
427 C<captures> used to be called snippets. This is still available for backwoards
428 compatibility, but is considered deprecated.
432 A convenient method to access $req->uploads.

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

477 $_ = [$_] unless ref($_) eq "ARRAY";
478 push( @$_, $upload );
482 $self->uploads->{$field} = $upload;
490 Returns a reference to a hash containing uploads. Values can be either a
491 L<Catalyst::Request::Upload> object, or an arrayref of
492 L<Catalyst::Request::Upload> objects.

508 Returns a URI object for the current request. Stringifies to the URI text.
510 =head2 $req->uri_with( { key => 'value' } );
512 Returns a rewritten URI object for the current request. Key/value pairs
513 passed in will override existing parameters. Unmodified pairs will be
519 my( $self, $args ) = @_;
521 carp( 'No arguments passed to uri_with()' ) unless $args;

525 for ( ref $value eq 'ARRAY' ? @$value : $value ) {
531 my $uri = $self->uri->clone;
534 %{ $uri->query_form_hash },
542 Returns the currently logged in user. Deprecated. The method recommended for
543 newer plugins is $c->user.
545 =head2 $req->user_agent
547 Shortcut to $req->headers->user_agent. Returns the user agent (browser)
