NAME

       Catalyst::Action::DeserializeMultiPart - Deserialize Data in a Multipart Request

SYNOPSIS

           package Foo::Controller::Bar;

           __PACKAGE__->config(
               # see Catalyst::Action::Deserialize for standard config
           );

           sub begin :ActionClass('DeserializeMultiPart') DeserializePart('REST') {}

DESCRIPTION

       This action will deserialize multipart HTTP POST, PUT, OPTIONS and DELETE requests.  It is
       a simple extension of Catalyst::Action::Deserialize with the exception that rather than
       using the entire request body (which may contain multiple sections), it will look for a
       single part in the request body named according to the "DeserializePart" attribute on that
       action (defaulting to "REST").  If a part is found under that name, it then proceeds to
       deserialize the request as normal based on the content-type of that individual part.  If
       no such part is found, the request would be processed as if no data was sent.

       This module's code will only come into play if the following conditions are met:

       •   The "Content-type" of the request is "multipart/*"

       •   The request body (as returned by "$c-"request->body> is not defined

       •   There is a part of the request body (as returned by
           "$c-"request->upload($DeserializePart)>) available

CONFIGURING HTTP::Body

       By default, HTTP::Body parses "multipart/*" requests as an HTTP::Body::OctetStream.
       HTTP::Body::OctetStream does not separate out the individual parts of the request body.
       In order to make use of the individual parts, HTTP::Body must be told which content types
       to map to HTTP::Body::MultiPart.  This module makes the assumption that you would like to
       have all "multipart/mixed" requests parsed by HTTP::Body::MultiPart module.  This is done
       by a package variable inside HTTP::Body: $HTTP::Body::Types (a HASH ref).

       WARNING: As this module modifies the behaviour of HTTP::Body globally, adding it to an
       application can have unintended consequences as multipart bodies will be parsed
       differently from before.

       Feel free to add other content-types to this hash if needed or if you would prefer that
       "multipart/mixed" NOT be added to this hash, simply delete it after loading this module.

           # in your controller
           use Catalyst::Action::DeserializeMultiPart;

           delete $HTTP::Body::Types->{'multipart/mixed'};
           $HTTP::Body::Types->{'multipart/my-crazy-content-type'} = 'HTTP::Body::MultiPart';
