34 | =head1 DESCRIPTION |
35 | |
8c464987 |
36 | Make subrequests to actions in Catalyst. Uses the catalyst |
37 | dispatcher, so it will work like an external url call. |
87c672db |
38 | Methods are provided both to get the body of the response and the full |
39 | response (L<Catalyst::Response>) object. |

45 | =item subreq [path as string or hash ref], [stash as hash ref], [parameters as hash ref] |
aae30f91 |
46 | |
47 | =item sub_request |
48 | |
4f38f6a7 |
49 | Takes a full path to a path you'd like to dispatch to. |
87c672db |
50 | |
51 | If the path is passed as a hash ref then it can include body, action, |
52 | match and path. |
53 | |
54 | An optional second argument as hashref can contain data to put into the |
55 | stash of the subrequest. |
56 | |
57 | An optional third argument as hashref can contain data to pass as |
58 | parameters to the subrequest. |
59 | |
60 | Returns the body of the response. |
61 | |
62 | =item subreq_res [path as string or hash ref], [stash as hash ref], [parameters as hash ref] |
63 | |
64 | =item sub_request_response |
65 | |
66 | Like C<sub_request()>, but returns a full L<Catalyst::Response> object. |
