NAME

Perinci::Object::EnvResultMulti - Represent enveloped result (multistatus)

VERSION

This document describes version 0.311 of Perinci::Object::EnvResultMulti (from Perl distribution Perinci-Object), released on 2020-01-02.

SYNOPSIS

 use Perinci::Object::EnvResultMulti;
 use Data::Dump; # for dd()

 sub myfunc {
     ...

     # if unspecified, the default status will be [200, "Success/no items"]
     my $envres = Perinci::Object::EnvResultMulti->new;

     # then you can add result for each item
     $envres->add_result(200, "OK", {item_id=>1});
     $envres->add_result(202, "OK", {item_id=>2, note=>"blah"});
     $envres->add_result(404, "Not found", {item_id=>3});
     ...

     # if you add a success status, the overall status will still be 200

     # if you add a non-success staus, the overall status will be 207, or
     # the non-success status (if no success has been added)

     # finally, return the result
     return $envres->as_struct;

     # the result from the above will be: [207, "Partial success", undef,
     # {results => [
     #     {success=>200, message=>"OK", item_id=>1},
     #     {success=>201, message=>"OK", item_id=>2, note=>"blah"},
     #     {success=>404, message=>"Not found", item_id=>3},
     # ]}]
 } # myfunc

To add a payload for each result:

 my $envres = Perinci::Object::EnvResultMulti->new;
 $envres->add_result(200, "OK", {item_id=>1, payload=>"a"});
 $envres->add_result(200, "OK", {item_id=>2, payload=>"b"});
 $envres->add_result(200, "OK", {item_id=>3, payload=>"c"});

 return $envres->as_struct;
 # => [200, "All success", ["a","b","c"], ...]

DESCRIPTION

This class is a subclass of Perinci::Object::EnvResult and provides a convenience method when you want to use multistatus/detailed per-item results (specified in Rinci 1.1.63: results result metadata property). In this case, response status can be 200, 207, or non-success. As you add more per-item results, this class will set/update the overall response status for you.

METHODS

new($res) => OBJECT

Create a new object from $res enveloped result array. If $res is not specified, the default is [200, "Success/no items"].

$envres->add_result($status, $message, \%extra)

Add an item result.

Extra keys:

  • item_id

  • payload

    If you want to add a payload for this result. The final overall payload will be an array composed from this payload.
