=head1 DESCRIPTION |
32
|
|
|
|
|
|
|
|
33
|
|
|
|
|
|
|
This is a simple subclass of HTTP::Request that does two things. |
34
|
|
|
|
|
|
|
First of all, it sets the Accept header to C as soon |
35
|
|
|
|
|
|
|
as it's created. Secondly, it implements a L |
36
|
|
|
|
|
|
|
method that adds the supplied data structure to the request, as JSON, |
37
|
|
|
|
|
|
|
or returns the current JSON contents as a Perl structure. |

|

|
|
|
|
A mutator for the request's JSON contents. |
61
|
|
|
|
|
|
|
|
62
|
|
|
|
|
|
|
As a setter, supplied with a valid JSON data structure, sets the request |
63
|
|
|
|
|
|
|
contents to be the JSON-encoded version of that data structure, and sets the |
64
|
|
|
|
|
|
|
Content-Type header to C. Will throw an exception if the |
65
|
|
|
|
|
|
|
data structure cannot be converted to JSON. Returns the resulting string |
66
|
|
|
|
|
|
|
contents. |
67
|
|
|
|
|
|
|
|
68
|
|
|
|
|
|
|
All strings in $perl_data must be Unicode strings, or you will get |
69
|
|
|
|
|
|
|
encoding errors. |
70
|
|
|
|
|
|
|
|
71
|
|
|
|
|
|
|
As a getter, decodes the request contents from JSON |
72
|
|
|
|
|
|
|
into a Perl structure, and returns the resulting data structure. |
