496 | =head1 DESCRIPTION |
497 | |
3e19f4f6 |
498 | This is the Catalyst Request class, which provides an interface to data for the |
499 | current client request. The request object is prepared by L<Catalyst::Engine>, |
500 | thus hiding the details of the particular engine implementation. |

502 | =head1 METHODS |
fc7ec1d9 |
503 | |
b5ecfcf0 |
504 | =head2 $req->address |
0556eb49 |
505 | |
3e19f4f6 |
506 | Returns the IP address of the client. |
61b1e958 |
507 | |
b5ecfcf0 |
508 | =head2 $req->arguments |
61b1e958 |
509 | |
b22c6668 |
510 | Returns a reference to an array containing the arguments. |
fc7ec1d9 |
511 | |
512 | print $c->request->arguments->[0]; |
513 | |
c436c1e8 |
514 | For example, if your action was |
515 | |
7d7519a4 |
516 | package MyApp::Controller::Foo; |
85d9fce6 |
517 | |
518 | sub moose : Local { |
519 | ... |
520 | } |
c436c1e8 |
521 | |
3e19f4f6 |
522 | and the URI for the request was C<http://.../foo/moose/bah>, the string C<bah> |
c436c1e8 |
523 | would be the first and only argument. |
524 | |
6d920953 |
525 | Arguments get automatically URI-unescaped for you. |

526 | |
b5ecfcf0 |
527 | =head2 $req->args |
3e19f4f6 |
528 | |
01011731 |
529 | Shortcut for L</arguments>. |
3e19f4f6 |
530 | |
b5ecfcf0 |
531 | =head2 $req->base |
fc7ec1d9 |
532 | |
328f225e |
533 | Contains the URI base. This will always have a trailing slash. Note that the |
f4dda4a8 |
534 | URI scheme (e.g., http vs. https) must be determined through heuristics; |
328f225e |
535 | depending on your server configuration, it may be incorrect. See $req->secure |
536 | for more info. |
c436c1e8 |
537 | |
3e19f4f6 |
538 | If your application was queried with the URI |
539 | C<http://localhost:3000/some/path> then C<base> is C<http://localhost:3000/>. |
fc7ec1d9 |
540 | |
b5ecfcf0 |
541 | =head2 $req->body |
06e1b616 |
542 | |
843871cf |
543 | Returns the message body of the request, as returned by L<HTTP::Body>: a string, |
544 | unless Content-Type is C<application/x-www-form-urlencoded>, C<text/xml>, or |
545 | C<multipart/form-data>, in which case a L<File::Temp> object is returned. |
e060fe05 |
546 | |
974733c0 |
547 | =head2 $req->body_data |
548 | |
549 | Returns a Perl representation of POST/PUT body data that is not classic HTML |
550 | form data, such as JSON, XML, etc. By default, Catalyst will parse incoming |
551 | data of the type 'application/json' and return access to that data via this |
552 | method. You may define addition data_handlers via a global configuration |
553 | setting. See L<Catalyst\DATA HANDLERS> for more information. |
554 | |
b94f8e72 |
555 | If the POST is malformed in some way (such as undefined or not content that |
556 | matches the content-type) we raise a L<Catalyst::Exception> with the error |
557 | text as the message. |
558 | |
566678d0 |
559 | If the POSTed content type does not match an available data handler, this |
b94f8e72 |
560 | will also raise an exception. |
561 | |
b5ecfcf0 |
562 | =head2 $req->body_parameters |
fbcc39ad |
563 | |
3e19f4f6 |
564 | Returns a reference to a hash containing body (POST) parameters. Values can |
fbcc39ad |
565 | be either a scalar or an arrayref containing scalars. |
566 | |
567 | print $c->request->body_parameters->{field}; |
568 | print $c->request->body_parameters->{field}->[0]; |
c436c1e8 |
569 | |
d631b5f9 |
570 | These are the parameters from the POST part of the request, if any. |
e5ecd5bc |
571 | |
0d94e986 |
572 | B<NOTE> If your POST is multipart, but contains non file upload parts (such |
b0ff1be8 |
573 | as an line part with an alternative encoding or content type) we do our best to |
574 | try and figure out how the value should be presented. If there's a specified character |
575 | set we will use that to decode rather than the default encoding set by the application. |
576 | However if there are complex headers and we cannot determine |
577 | the correct way to extra a meaningful value from the upload, in this case any |
0d94e986 |
578 | part like this will be represented as an instance of L<Catalyst::Request::PartData>. |
579 | |
b0ff1be8 |
580 | Patches and review of this part of the code welcomed. |

598 | =head2 $req->cookie |
3ad654e0 |
599 | |
3e19f4f6 |
600 | A convenient method to access $req->cookies. |
3ad654e0 |
601 | |
602 | $cookie = $c->request->cookie('name'); |
603 | @cookies = $c->request->cookie; |

625 | |
b5ecfcf0 |
626 | =head2 $req->cookies |
fc7ec1d9 |
627 | |
b22c6668 |
628 | Returns a reference to a hash containing the cookies. |
fc7ec1d9 |
629 | |
630 | print $c->request->cookies->{mycookie}->value; |
631 | |
7e743798 |
632 | The cookies in the hash are indexed by name, and the values are L<CGI::Simple::Cookie> |
c436c1e8 |
633 | objects. |
634 | |
b5ecfcf0 |
635 | =head2 $req->header |
b5176d9e |

638 | |
b5ecfcf0 |
639 | =head2 $req->headers |
fc7ec1d9 |

642 | |
643 | print $c->request->headers->header('X-Catalyst'); |
644 | |
b5ecfcf0 |
645 | =head2 $req->hostname |
0556eb49 |
646 | |
178dca5f |
647 | Returns the hostname of the client. Use C<< $req->uri->host >> to get the hostname of the server. |
e5ecd5bc |
648 | |
b5ecfcf0 |
649 | =head2 $req->input |
61bacdcc |
650 | |
3e19f4f6 |
651 | Alias for $req->body. |
61bacdcc |
652 | |
3b4d1251 |
653 | =head2 $req->query_keywords |
654 | |
655 | Contains the keywords portion of a query string, when no '=' signs are |
656 | present. |
657 | |
658 | http://localhost/path?some+keywords |
b0ad47c1 |
659 | |
3b4d1251 |
660 | $c->request->query_keywords will contain 'some keywords' |
661 | |
b5ecfcf0 |
662 | =head2 $req->match |
fc7ec1d9 |
663 | |
3e19f4f6 |
664 | This contains the matching part of a Regex action. Otherwise |
2c83fd5a |
665 | it returns the same as 'action', except for default actions, |
666 | which return an empty string. |
fc7ec1d9 |
667 | |
b5ecfcf0 |
668 | =head2 $req->method |
b5176d9e |
669 | |
670 | Contains the request method (C<GET>, C<POST>, C<HEAD>, etc). |
671 | |
b5ecfcf0 |
672 | =head2 $req->param |
e7c0c583 |
673 | |
b0ad47c1 |
674 | Returns GET and POST parameters with a CGI.pm-compatible param method. This |
3e19f4f6 |
675 | is an alternative method for accessing parameters in $c->req->parameters. |
e7c0c583 |
676 | |
a82c2894 |
677 | $value = $c->request->param( 'foo' ); |
678 | @values = $c->request->param( 'foo' ); |
e7c0c583 |
679 | @params = $c->request->param; |
680 | |
3e705254 |
681 | Like L<CGI>, and B<unlike> earlier versions of Catalyst, passing multiple |
a82c2894 |
682 | arguments to this method, like this: |
683 | |
85d9fce6 |
684 | $c->request->param( 'foo', 'bar', 'gorch', 'quxx' ); |
a82c2894 |
685 | |
686 | will set the parameter C<foo> to the multiple values C<bar>, C<gorch> and |
687 | C<quxx>. Previously this would have added C<bar> as another value to C<foo> |
3e19f4f6 |
688 | (creating it if it didn't exist before), and C<quxx> as another value for |
689 | C<gorch>. |
a82c2894 |
690 | |
83312afd |
691 | B<NOTE> this is considered a legacy interface and care should be taken when |
692 | using it. C<< scalar $c->req->param( 'foo' ) >> will return only the first |
693 | C<foo> param even if multiple are present; C<< $c->req->param( 'foo' ) >> will |
694 | return a list of as many are present, which can have unexpected consequences |
695 | when writing code of the form: |
696 | |
697 | $foo->bar( |
698 | a => 'b', |
699 | baz => $c->req->param( 'baz' ), |
700 | ); |
701 | |
702 | If multiple C<baz> parameters are provided this code might corrupt data or |
703 | cause a hash initialization error. For a more straightforward interface see |
704 | C<< $c->req->parameters >>. |
705 | |
f384c848 |
706 | B<NOTE> Interfaces like this, which are based on L<CGI> and the C<param> method |
ac1cf8d4 |
707 | are known to cause demonstrated exploits. It is highly recommended that you |
708 | avoid using this method, and migrate existing code away from it. Here's a |
f384c848 |
709 | whitepaper of the exploit: |
0810283f |
710 | |
711 | L<http://blog.gerv.net/2014/10/new-class-of-vulnerability-in-perl-web-applications/> |
712 | |
ac1cf8d4 |
713 | B<NOTE> Further discussion on IRC indicate that the L<Catalyst> core team from 'back then' |
714 | were well aware of this hack and this is the main reason we added the new approach to |
715 | getting parameters in the first place. |
716 | |
0810283f |
717 | Basically this is an exploit that takes advantage of how L<\param> will do one thing |
718 | in scalar context and another thing in list context. This is combined with how Perl |
719 | chooses to deal with duplicate keys in a hash definition by overwriting the value of |
720 | existing keys with a new value if the same key shows up again. Generally you will be |
566678d0 |
721 | vulnerable to this exploit if you are using this method in a direct assignment in a |
0810283f |
722 | hash, such as with a L<DBIx::Class> create statement. For example, if you have |
723 | parameters like: |
724 | |
725 | user?user=123&foo=a&foo=user&foo=456 |
726 | |
727 | You could end up with extra parameters injected into your method calls: |
728 | |
729 | $c->model('User')->create({ |
730 | user => $c->req->param('user'), |
731 | foo => $c->req->param('foo'), |
732 | }); |
733 | |
734 | Which would look like: |
735 | |
736 | $c->model('User')->create({ |
737 | user => 123, |
738 | foo => qw(a user 456), |
739 | }); |
740 | |
741 | (or to be absolutely clear if you are not seeing it): |
742 | |
743 | $c->model('User')->create({ |
744 | user => 456, |
745 | foo => 'a', |
746 | }); |
747 | |
748 | Possible remediations include scrubbing your parameters with a form validator like |
749 | L<HTML::FormHandler> or being careful to force scalar context using the scalar |
750 | keyword: |
751 | |
752 | $c->model('User')->create({ |
753 | user => scalar($c->req->param('user')), |
754 | foo => scalar($c->req->param('foo')), |
755 | }); |
756 | |
f384c848 |
757 | Upcoming versions of L<Catalyst> will disable this interface by default and require |
758 | you to positively enable it should you require it for backwards compatibility reasons. |

885 | PSGI servers may make this determination in different ways (as by |
886 | directly passing along information from the server, interpreting any of |

967 | =head2 $req->mangle_params( { key => 'value' }, $appendmode); |
bd917b94 |
968 | |
a375a206 |
969 | Returns a hashref of parameters stemming from the current request's params, |
970 | plus the ones supplied. Keys for which no current param exists will be |
971 | added, keys with undefined values will be removed and keys with existing |
972 | params will be replaced. Note that you can supply a true value as the final |
973 | argument to change behavior with regards to existing parameters, appending |
974 | values rather than replacing them. |
975 | |
976 | A quick example: |
977 | |
978 | # URI query params foo=1 |
979 | my $hashref = $req->mangle_params({ foo => 2 }); |
980 | # Result is query params of foo=2 |
981 | |
982 | versus append mode: |
983 | |
984 | # URI query params foo=1 |
985 | my $hashref = $req->mangle_params({ foo => 2 }, 1); |
986 | # Result is query params of foo=1&foo=2 |
