139 Catalyst::Request - provides information about the current client request
150 $req->body_parameters;
151 $req->content_encoding;
152 $req->content_length;
160 $req->query_keywords;
168 $req->query_parameters;
172 $req->captures; # previously knows as snippets
179 See also L<Catalyst>, L<Catalyst::Request::Upload>.
183 This is the Catalyst Request class, which provides an interface to data for the
184 current client request. The request object is prepared by L<Catalyst::Engine>,
185 thus hiding the details of the particular engine implementation.
191 [DEPRECATED] Returns the name of the requested action.
194 Use C<< $c->action >> instead (which returns a
195 L<Catalyst::Action|Catalyst::Action> object).
199 Returns the IP address of the client.
201 =head2 $req->arguments
203 Returns a reference to an array containing the arguments.
205 print $c->request->arguments->[0];
207 For example, if your action was
209 package MyApp::C::Foo;
215 and the URI for the request was C<http://.../foo/moose/bah>, the string C<bah>
216 would be the first and only argument.
220 Shortcut for arguments.
224 Contains the URI base. This will always have a trailing slash.
226 If your application was queried with the URI
227 C<http://localhost:3000/some/path> then C<base> is C<http://localhost:3000/>.
231 Returns the message body of the request, unless Content-Type is
232 C<application/x-www-form-urlencoded> or C<multipart/form-data>.
234 =head2 $req->body_parameters
236 Returns a reference to a hash containing body (POST) parameters. Values can
237 be either a scalar or an arrayref containing scalars.
239 print $c->request->body_parameters->{field};
240 print $c->request->body_parameters->{field}->[0];
242 These are the parameters from the POST part of the request, if any.
244 =head2 $req->body_params
246 Shortcut for body_parameters.
248 =head2 $req->content_encoding
250 Shortcut for $req->headers->content_encoding.
252 =head2 $req->content_length
254 Shortcut for $req->headers->content_length.
256 =head2 $req->content_type
258 Shortcut for $req->headers->content_type.
262 A convenient method to access $req->cookies.
264 $cookie = $c->request->cookie('name');
265 @cookies = $c->request->cookie;
273 return keys %{ $self->cookies };
280 unless ( exists $self->cookies->{$name} ) {
284 return $self->cookies->{$name};
290 Returns a reference to a hash containing the cookies.
292 print $c->request->cookies->{mycookie}->value;
294 The cookies in the hash are indexed by name, and the values are L<CGI::Cookie>
299 Shortcut for $req->headers->header.
303 Returns an L<HTTP::Headers> object containing the headers for the current request.
305 print $c->request->headers->header('X-Catalyst');
307 =head2 $req->hostname
309 Returns the hostname of the client.
313 Alias for $req->body.
315 =head2 $req->query_keywords
317 Contains the keywords portion of a query string, when no '=' signs are
320 http://localhost/path?some+keywords
322 $c->request->query_keywords will contain 'some keywords'
326 This contains the matching part of a Regex action. Otherwise
327 it returns the same as 'action', except for default actions,
328 which return an empty string.
332 Contains the request method (C<GET>, C<POST>, C<HEAD>, etc).
336 Returns GET and POST parameters with a CGI.pm-compatible param method. This
337 is an alternative method for accessing parameters in $c->req->parameters.
339 $value = $c->request->param( 'foo' );
340 @values = $c->request->param( 'foo' );
341 @params = $c->request->param;
343 Like L<CGI>, and B<unlike> earlier versions of Catalyst, passing multiple
344 arguments to this method, like this:
346 $c->request->param( 'foo', 'bar', 'gorch', 'quxx' );
348 will set the parameter C<foo> to the multiple values C<bar>, C<gorch> and
349 C<quxx>. Previously this would have added C<bar> as another value to C<foo>
350 (creating it if it didn't exist before), and C<quxx> as another value for
359 return keys %{ $self->parameters };
366 unless ( exists $self->parameters->{$param} ) {
367 return wantarray ? () : undef;
370 if ( ref $self->parameters->{$param} eq 'ARRAY' ) {
372 ? @{ $self->parameters->{$param} }
373 : $self->parameters->{$param}->[0];
377 ? ( $self->parameters->{$param} )
378 : $self->parameters->{$param};
383 $self->parameters->{$field} = [@_];
387 =head2 $req->parameters
389 Returns a reference to a hash containing GET and POST parameters. Values can
390 be either a scalar or an arrayref containing scalars.
392 print $c->request->parameters->{field};
393 print $c->request->parameters->{field}->[0];
395 This is the combination of C<query_parameters> and C<body_parameters>.
399 Shortcut for $req->parameters.
403 Returns the path, i.e. the part of the URI after $req->base, for the current request.
405 =head2 $req->path_info
407 Alias for path, added for compability with L<CGI>.
412 my ( $self, @params ) = @_;
415 $self->uri->path(@params);
418 elsif ( $self->_has_path ) {
422 my $path = $self->uri->path;
423 my $location = $self->base->path;
424 $path =~ s/^(\Q$location\E)?//;
432 =head2 $req->protocol
434 Returns the protocol (HTTP/1.0 or HTTP/1.1) used for the current request.
436 =head2 $req->query_parameters
438 =head2 $req->query_params
440 Returns a reference to a hash containing query string (GET) parameters. Values can
441 be either a scalar or an arrayref containing scalars.
443 print $c->request->query_parameters->{field};
444 print $c->request->query_parameters->{field}->[0];
446 =head2 $req->read( [$maxlength] )
448 Reads a chunk of data from the request body. This method is intended to be
449 used in a while loop, reading $maxlength bytes on every call. $maxlength
450 defaults to the size of the request if not specified.
452 You have to set MyApp->config->{parse_on_demand} to use this directly.
456 Shortcut for $req->headers->referer. Returns the referring page.
460 Returns true or false, indicating whether the connection is secure (https).
462 =head2 $req->captures
464 Returns a reference to an array containing captured args from chained
465 actions or regex captures.
467 my @captures = @{ $c->request->captures };
469 =head2 $req->snippets
471 C<captures> used to be called snippets. This is still available for backwoards
472 compatibility, but is considered deprecated.
476 A convenient method to access $req->uploads.
478 $upload = $c->request->upload('field');
479 @uploads = $c->request->upload('field');
480 @fields = $c->request->upload;
482 for my $upload ( $c->request->upload('field') ) {
483 print $upload->filename;
492 return keys %{ $self->uploads };
499 unless ( exists $self->uploads->{$upload} ) {
500 return wantarray ? () : undef;
503 if ( ref $self->uploads->{$upload} eq 'ARRAY' ) {
505 ? @{ $self->uploads->{$upload} }
506 : $self->uploads->{$upload}->[0];
510 ? ( $self->uploads->{$upload} )
511 : $self->uploads->{$upload};
517 while ( my ( $field, $upload ) = splice( @_, 0, 2 ) ) {
519 if ( exists $self->uploads->{$field} ) {
520 for ( $self->uploads->{$field} ) {
521 $_ = [$_] unless ref($_) eq "ARRAY";
522 push( @$_, $upload );
526 $self->uploads->{$field} = $upload;
534 Returns a reference to a hash containing uploads. Values can be either a
535 L<Catalyst::Request::Upload> object, or an arrayref of
536 L<Catalyst::Request::Upload> objects.
538 my $upload = $c->request->uploads->{field};
539 my $upload = $c->request->uploads->{field}->[0];
543 Returns a URI object for the current request. Stringifies to the URI text.
545 =head2 $req->uri_with( { key => 'value' } );
547 Returns a rewritten URI object for the current request. Key/value pairs
548 passed in will override existing parameters. You can remove an existing
549 parameter by passing in an undef value. Unmodified pairs will be
555 my( $self, $args ) = @_;
557 carp( 'No arguments passed to uri_with()' ) unless $args;
559 foreach my $value ( values %$args ) {
560 next unless defined $value;
561 for ( ref $value eq 'ARRAY' ? @$value : $value ) {
563 utf8::encode( $_ ) if utf8::is_utf8($_);
567 my $uri = $self->uri->clone;
568 my %query = ( %{ $uri->query_form_hash }, %$args );
571 # remove undef values
572 map { defined $query{ $_ } ? ( $_ => $query{ $_ } ) : () } keys %query
579 Returns the currently logged in user. Deprecated. The method recommended for
580 newer plugins is $c->user.
582 =head2 $req->user_agent
584 Shortcut to $req->headers->user_agent. Returns the user agent (browser)
