NAME

Sisimai::Message::JSON - Convert bounce object (decoded JSON) to data structure.

SYNOPSIS

    use JSON;
    use Sisimai::Message;
    my $jsonparser = JSON->new;
    my $jsonobject = $jsonparser->decode($jsonstring);
    my $messageobj = Sisimai::Message->new('data' => $jsonobject, 'input' => 'json');

DESCRIPTION

Sisimai::Message::JSON convert bounce object (decode JSON) to data structure. When the email given as a argument of "new()" method is not a decoded JSON, the method returns "undef".

CLASS METHODS

"new(Hash reference)"

"new()" is a constructor of Sisimai::Message

    my $jsonparser = JSON->new;
    my $jsonstring = '{"neko":2, "nyaan": "meow", ...}';
    my $jsonobject = $jsonparser->decode($jsonstring);
    my $messageobj = Sisimai::Message->new('data' => $jsonobject, 'input' => 'json');

If you have implemented a custom MTA module and use it, set the value of "load" in the argument of this method as an array reference like following code:

    my $messageobj = Sisimai::Message->new(
                        'data'  => $jsonobject,
                        'load'  => ['Your::Custom::MTA::Module']
                        'input' => 'json',
                  );

Beginning from v4.19.0, `hook` argument is available to callback user defined method like the following codes:

    my $callbackto = sub {
        my $argv = shift;
        my $data = { 'feedback-id' => '', 'account-id' => '' };
        my $mesg = $argv->{'message'} || {};
        if( exists $mesg->{'feedbackId'} ) {
            $data->{'feedback-id'} = $mesg->{'feedback-Id'};
        }
        if( exists $mesg->{'sendingAccountId'} ) {
            $data->{'account-id'} = $mesg->{'sendingAccountId'};
        }
        return $data;
    };
    my $messageobj = Sisimai::Message->new(
                        'data'  => $jsonobject,
                        'hook'  => $callbackto,
                        'input' => 'json' );
    print $message->catch->{'feedback-id'};    # 01010157e48fa03f-c7e948fe-...
