Unable to POST multiple multipart parameters

[Arjan]

It's seems that POST-ing multiple multipart paramaters is not possible; the GuzzleHttp\Command\Guzzle\RequestLocation\MultiPartLocation overwrites the body for every parameter. So we end up with only the last parameter in the body.

use GuzzleHttp\Client;
use GuzzleHttp\Command\Guzzle\GuzzleClient;
use GuzzleHttp\Command\Guzzle\Description;

$client = new Client();
$description = new Description([
    'baseUri' => 'http://httpbin.org/',
    'operations' => [
        'testing' => [
            'httpMethod' => 'POST',
            'uri' => '/post',
            'responseModel' => 'postResponse',
            'parameters' => [
                'foo' => [
                    'type' => 'string',
                    'location' => 'multipart'
                ],
                'baz' => [
                    'type' => 'string',
                    'location' => 'multipart'
                ]
            ]
        ]
    ],
    'models' => [
        'postResponse' => [
            'type' => 'object',
            'additionalProperties' => [
                'location' => 'json'
            ]
        ]
    ]
]);

$guzzleClient = new GuzzleClient($client, $description);

$result = $guzzleClient->testing(['foo' => 'bar', 'baz' => 'qux']);
echo (string) $result;

Will result in:

GuzzleHttp\Command\Result Object
(
    [args] => Array
        (
        )
    [data] => 
    [files] => Array
        (
        )
    [form] => Array
        (
            [baz] => qux
        )
    [headers] => Array
        (
            [Content-Length] => 106
            [Content-Type] => multipart/form-data; boundary=585a331a19fcb
            [Host] => httpbin.org
            [User-Agent] => GuzzleHttp/6.2.1 curl/7.49.1 PHP/7.1.0
        )
    [json] => 
    [origin] => 127.0.0.1
    [url] => http://httpbin.org/post
)

Can you try latest develop branch. In case you want to send a file use any as param type.
