50 | =head1 DESCRIPTION |
51 | |
52 | Catalyst::Controller::REST implements a mechanism for building |
53 | RESTful services in Catalyst. It does this by extending the |
db8bb647 |
54 | normal Catalyst dispatch mechanism to allow for different |
55 | subroutines to be called based on the HTTP Method requested, |
398c5a1b |
56 | while also transparently handling all the serialization/deserialization for |
57 | you. |
58 | |
59 | This is probably best served by an example. In the above |
60 | controller, we have declared a Local Catalyst action on |
db8bb647 |
61 | "sub thing", and have used the ActionClass('REST'). |
398c5a1b |
62 | |
63 | Below, we have declared "thing_GET" and "thing_PUT". Any |
db8bb647 |
64 | GET requests to thing will be dispatched to "thing_GET", |
65 | while any PUT requests will be dispatched to "thing_PUT". |
398c5a1b |
66 | |
e601adda |
67 | Any unimplemented HTTP methods will be met with a "405 Method Not Allowed" |
68 | response, automatically containing the proper list of available methods. You |
69 | can override this behavior through implementing a custom |
db8bb647 |
70 | C<thing_not_implemented> method. |
e601adda |
71 | |
72 | If you do not provide an OPTIONS handler, we will respond to any OPTIONS |
73 | requests with a "200 OK", populating the Allowed header automatically. |
74 | |
75 | Any data included in C<< $c->stash->{'rest'} >> will be serialized for you. |
76 | The serialization format will be selected based on the content-type |
77 | of the incoming request. It is probably easier to use the L<STATUS HELPERS>, |
78 | which are described below. |
398c5a1b |
79 | |
10bcd217 |
80 | "The HTTP POST, PUT, and OPTIONS methods will all automatically |
81 | L<deserialize|Catalyst::Action::Deserialize> the contents of |
82 | C<< $c->request->body >> into the C<< $c->request->data >> hashref", based on |
83 | the request's C<Content-type> header. A list of understood serialization |
84 | formats is L<below|/AVAILABLE SERIALIZERS>. |
398c5a1b |
85 | |
e601adda |
86 | If we do not have (or cannot run) a serializer for a given content-type, a 415 |
db8bb647 |
87 | "Unsupported Media Type" error is generated. |
398c5a1b |
88 | |
89 | To make your Controller RESTful, simply have it |
90 | |
5cb5f6bb |
91 | BEGIN { extends 'Catalyst::Controller::REST' } |
398c5a1b |
92 | |
9cd203c9 |
93 | =head1 CONFIGURATION |
94 | |
95 | See L<Catalyst::Action::Serialize/CONFIGURATION>. Note that the C<serialize> |
96 | key has been deprecated. |
97 | |
398c5a1b |
98 | =head1 SERIALIZATION |
99 | |
100 | Catalyst::Controller::REST will automatically serialize your |
e601adda |
101 | responses, and deserialize any POST, PUT or OPTIONS requests. It evaluates |
102 | which serializer to use by mapping a content-type to a Serialization module. |
db8bb647 |
103 | We select the content-type based on: |
e601adda |
104 | |
5cb5f6bb |
105 | =over |
e601adda |
106 | |
107 | =item B<The Content-Type Header> |
108 | |
109 | If the incoming HTTP Request had a Content-Type header set, we will use it. |
110 | |
111 | =item B<The content-type Query Parameter> |
112 | |
113 | If this is a GET request, you can supply a content-type query parameter. |
114 | |
115 | =item B<Evaluating the Accept Header> |
116 | |
117 | Finally, if the client provided an Accept header, we will evaluate |
db8bb647 |
118 | it and use the best-ranked choice. |
e601adda |

121 | |
122 | =head1 AVAILABLE SERIALIZERS |
123 | |
124 | A given serialization mechanism is only available if you have the underlying |
125 | modules installed. For example, you can't use XML::Simple if it's not already |
db8bb647 |
126 | installed. |
e601adda |
127 | |
95318468 |
128 | In addition, each serializer has its quirks in terms of what sorts of data |
e601adda |
129 | structures it will properly handle. L<Catalyst::Controller::REST> makes |
db8bb647 |
130 | no attempt to save you from yourself in this regard. :) |

134 | =item * C<text/x-yaml> => C<YAML::Syck> |
e601adda |
135 | |
136 | Returns YAML generated by L<YAML::Syck>. |
137 | |
95318468 |
138 | =item * C<text/html> => C<YAML::HTML> |
e601adda |
139 | |
140 | This uses L<YAML::Syck> and L<URI::Find> to generate YAML with all URLs turned |
141 | to hyperlinks. Only useable for Serialization. |
142 | |
95318468 |
143 | =item * C<application/json> => C<JSON> |
e601adda |
144 | |
db8bb647 |
145 | Uses L<JSON> to generate JSON output. It is strongly advised to also have |
e540a1fa |
146 | L<JSON::XS> installed. The C<text/x-json> content type is supported but is |
147 | deprecated and you will receive warnings in your log. |

149 | =item * C<text/x-data-dumper> => C<Data::Serializer> |
e601adda |
150 | |
151 | Uses the L<Data::Serializer> module to generate L<Data::Dumper> output. |
152 | |
95318468 |
153 | =item * C<text/x-data-denter> => C<Data::Serializer> |
e601adda |

155 | Uses the L<Data::Serializer> module to generate L<Data::Denter> output. |
156 | |
95318468 |
157 | =item * C<text/x-data-taxi> => C<Data::Serializer> |

163 | Uses the L<Data::Serializer> module to generate L<Storable> output. |
164 | |
95318468 |
165 | =item * C<application/x-freezethaw> => C<Data::Serializer> |
e601adda |
166 | |
167 | Uses the L<Data::Serializer> module to generate L<FreezeThaw> output. |
168 | |
95318468 |
169 | =item * C<text/x-config-general> => C<Data::Serializer> |
e601adda |
170 | |
171 | Uses the L<Data::Serializer> module to generate L<Config::General> output. |
172 | |
95318468 |
173 | =item * C<text/x-php-serialization> => C<Data::Serializer> |
e601adda |
174 | |
175 | Uses the L<Data::Serializer> module to generate L<PHP::Serialization> output. |
176 | |
95318468 |
177 | =item * C<text/xml> => C<XML::Simple> |
e601adda |
178 | |
179 | Uses L<XML::Simple> to generate XML output. This is probably not suitable |
180 | for any real heavy XML work. Due to L<XML::Simple>s requirement that the data |
181 | you serialize be a HASHREF, we transform outgoing data to be in the form of: |
182 | |
183 | { data => $yourdata } |
184 | |
95318468 |
185 | =item * L<View> |
9a76221e |
186 | |
db8bb647 |
187 | Uses a regular Catalyst view. For example, if you wanted to have your |
3d8a0645 |
188 | C<text/html> and C<text/xml> views rendered by TT, set: |
189 | |
190 | __PACKAGE__->config( |
191 | map => { |
192 | 'text/html' => [ 'View', 'TT' ], |
193 | 'text/xml' => [ 'View', 'XML' ], |
194 | } |
5cb5f6bb |
195 | ); |
3d8a0645 |
196 | |
197 | Your views should have a C<process> method like this: |
198 | |
199 | sub process { |
200 | my ( $self, $c, $stash_key ) = @_; |
5cb5f6bb |
201 | |
3d8a0645 |
202 | my $output; |
203 | eval { |
204 | $output = $self->serialize( $c->stash->{$stash_key} ); |
205 | }; |
206 | return $@ if $@; |
5cb5f6bb |
207 | |
3d8a0645 |
208 | $c->response->body( $output ); |
209 | return 1; # important |
210 | } |
211 | |
212 | sub serialize { |
213 | my ( $self, $data ) = @_; |
5cb5f6bb |
214 | |
3d8a0645 |
215 | my $serialized = ... process $data here ... |
5cb5f6bb |
216 | |
3d8a0645 |
217 | return $serialized; |
218 | } |
9a76221e |
219 | |
e601adda |
220 | =back |
221 | |
95318468 |
222 | By default, L<Catalyst::Controller::REST> will return a |
223 | C<415 Unsupported Media Type> response if an attempt to use an unsupported |
224 | content-type is made. You can ensure that something is always returned by |
225 | setting the C<default> config option: |
398c5a1b |
226 | |
5cb5f6bb |
227 | __PACKAGE__->config(default => 'text/x-yaml'); |
398c5a1b |
228 | |
95318468 |
229 | would make it always fall back to the serializer plugin defined for |
230 | C<text/x-yaml>. |
398c5a1b |

e601adda |
232 | =head1 CUSTOM SERIALIZERS |
233 | |
95318468 |
234 | Implementing new Serialization formats is easy! Contributions |
235 | are most welcome! If you would like to implement a custom serializer, |
236 | you should create two new modules in the L<Catalyst::Action::Serialize> |
237 | and L<Catalyst::Action::Deserialize> namespace. Then assign your new |
238 | class to the content-type's you want, and you're done. |
239 | |
240 | See L<Catalyst::Action::Serialize> and L<Catalyst::Action::Deserialize> |
241 | for more information. |

243 | =head1 STATUS HELPERS |
244 | |
e601adda |
245 | Since so much of REST is in using HTTP, we provide these Status Helpers. |
246 | Using them will ensure that you are responding with the proper codes, |
247 | headers, and entities. |
248 | |
398c5a1b |
249 | These helpers try and conform to the HTTP 1.1 Specification. You can |
db8bb647 |
250 | refer to it at: L<http://www.w3.org/Protocols/rfc2616/rfc2616.txt>. |
398c5a1b |
251 | These routines are all implemented as regular subroutines, and as |
252 | such require you pass the current context ($c) as the first argument. |

481 | =head1 MANUAL RESPONSES |
482 | |
483 | If you want to construct your responses yourself, all you need to |
484 | do is put the object you want serialized in $c->stash->{'rest'}. |
485 | |

486 | =head1 IMPLEMENTATION DETAILS |
487 | |
488 | This Controller ties together L<Catalyst::Action::REST>, |
489 | L<Catalyst::Action::Serialize> and L<Catalyst::Action::Deserialize>. It should be suitable for most applications. You should be aware that it: |

493 | =item Configures the Serialization Actions |
494 | |
495 | This class provides a default configuration for Serialization. It is currently: |
496 | |
497 | __PACKAGE__->config( |
95318468 |
498 | 'stash_key' => 'rest', |
499 | 'map' => { |
500 | 'text/html' => 'YAML::HTML', |
501 | 'text/xml' => 'XML::Simple', |
502 | 'text/x-yaml' => 'YAML', |
503 | 'application/json' => 'JSON', |
504 | 'text/x-json' => 'JSON', |
505 | 'text/x-data-dumper' => [ 'Data::Serializer', 'Data::Dumper' ], |
506 | 'text/x-data-denter' => [ 'Data::Serializer', 'Data::Denter' ], |
507 | 'text/x-data-taxi' => [ 'Data::Serializer', 'Data::Taxi' ], |
508 | 'application/x-storable' => [ 'Data::Serializer', 'Storable' ], |
509 | 'application/x-freezethaw' => [ 'Data::Serializer', 'FreezeThaw' ], |
510 | 'text/x-config-general' => [ 'Data::Serializer', 'Config::General' ], |
511 | 'text/x-php-serialization' => [ 'Data::Serializer', 'PHP::Serialization' ], |
512 | }, |
e601adda |
513 | ); |
514 | |
515 | You can read the full set of options for this configuration block in |
516 | L<Catalyst::Action::Serialize>. |
517 | |
518 | =item Sets a C<begin> and C<end> method for you |
519 | |
520 | The C<begin> method uses L<Catalyst::Action::Deserialize>. The C<end> |
521 | method uses L<Catalyst::Action::Serialize>. If you want to override |
522 | either behavior, simply implement your own C<begin> and C<end> actions |

547 | =head1 A MILD WARNING |
548 | |
549 | I have code in production using L<Catalyst::Controller::REST>. That said, |
550 | it is still under development, and it's possible that things may change |
551 | between releases. I promise to not break things unneccesarily. :) |
