75 | =head1 DESCRIPTION |
76 | |
3e19f4f6 |
77 | This is the Catalyst Request class, which provides an interface to data for the |
78 | current client request. The request object is prepared by L<Catalyst::Engine>, |
79 | thus hiding the details of the particular engine implementation. |

81 | =head1 METHODS |
fc7ec1d9 |
82 | |
b5ecfcf0 |
83 | =head2 $req->action |
fc7ec1d9 |
84 | |
aae8d418 |
85 | [DEPRECATED] Returns the name of the requested action. |
86 | |
87 | |
88 | Use C<< $c->action >> instead (which returns a |
89 | L<Catalyst::Action|Catalyst::Action> object). |
fc7ec1d9 |
90 | |
b5ecfcf0 |
91 | =head2 $req->address |
0556eb49 |
92 | |
3e19f4f6 |
93 | Returns the IP address of the client. |
61b1e958 |
94 | |
b5ecfcf0 |
95 | =head2 $req->arguments |
61b1e958 |
96 | |
b22c6668 |
97 | Returns a reference to an array containing the arguments. |
fc7ec1d9 |
98 | |
99 | print $c->request->arguments->[0]; |
100 | |
c436c1e8 |
101 | For example, if your action was |
102 | |
85d9fce6 |
103 | package MyApp::C::Foo; |
104 | |
105 | sub moose : Local { |
106 | ... |
107 | } |
c436c1e8 |
108 | |
3e19f4f6 |
109 | and the URI for the request was C<http://.../foo/moose/bah>, the string C<bah> |
c436c1e8 |
110 | would be the first and only argument. |
111 | |
b5ecfcf0 |
112 | =head2 $req->args |
3e19f4f6 |
113 | |
114 | Shortcut for arguments. |
115 | |
b5ecfcf0 |
116 | =head2 $req->base |
fc7ec1d9 |
117 | |
c436c1e8 |
118 | Contains the URI base. This will always have a trailing slash. |
119 | |
3e19f4f6 |
120 | If your application was queried with the URI |
121 | C<http://localhost:3000/some/path> then C<base> is C<http://localhost:3000/>. |

b5ecfcf0 |
272 | =head2 $req->match |
fc7ec1d9 |
273 | |
3e19f4f6 |
274 | This contains the matching part of a Regex action. Otherwise |
2c83fd5a |
275 | it returns the same as 'action', except for default actions, |
276 | which return an empty string. |
fc7ec1d9 |
277 | |

278 | =head2 $req->method |
b5176d9e |

282 | =head2 $req->param |
e7c0c583 |
283 | |
3e19f4f6 |
284 | Returns GET and POST parameters with a CGI.pm-compatible param method. This |
285 | is an alternative method for accessing parameters in $c->req->parameters. |
e7c0c583 |
286 | |
a82c2894 |
287 | $value = $c->request->param( 'foo' ); |

289 | @params = $c->request->param; |
290 | |
3e705254 |
291 | Like L<CGI>, and B<unlike> earlier versions of Catalyst, passing multiple |
a82c2894 |
292 | arguments to this method, like this: |
293 | |
85d9fce6 |
294 | $c->request->param( 'foo', 'bar', 'gorch', 'quxx' ); |
a82c2894 |
295 | |
296 | will set the parameter C<foo> to the multiple values C<bar>, C<gorch> and |
297 | C<quxx>. Previously this would have added C<bar> as another value to C<foo> |
3e19f4f6 |
298 | (creating it if it didn't exist before), and C<quxx> as another value for |
299 | C<gorch>. |
