Convert cURL to Guzzle POST with --form-params and --header - forms

Question

I'm struggling with a given curl-request which I want to handle over guzzle.
The curl-request looks like this:
curl --location --request POST "https://apis.myrest.com" \
--header "Content-Type: multipart/form-data" \
--header "Authorization: Bearer YOUR-BEARER-TOKEN" \
--form "mediaUrl=https://myfile.mpg" \
--form "configuration={
\"speechModel\": { \"language\": \"en-US\" },
\"publish\": {
\"callbacks\": [{
\"url\" : \"https://example.org/callback\"
}]
}
}
And I want it to send via guzzle like that:
// 1. build guzzle client:
//----------------------------------------------------------------------
$this->client = new Client([
'base_uri' => $this->config->getBaseUri(),
]);
// 2. build guzzle request:
//----------------------------------------------------------------------
$request = new Request(
'POST',
'myendpoint',
[
'authorization' => 'Bearer ' . $this->config->getApiToken(),
'cache-control' => 'no-cache',
'content-type' => 'application/json',
// maybe here, or not?
form_params => ['mediaUrl' => 'www.media.com'],
]
);
// 3. send via client
//----------------------------------------------------------------------
response = $this->client->send($request, ['timeout' => self::TIMEOUT]);
My problem now is, that I have no clue how to handle this. In guzzle's documentation i found "form_params":
http://docs.guzzlephp.org/en/stable/quickstart.html#making-a-request#post-form-requests
But it does not seem to work. If I add the form_params-array to my request, the receiver does not get them. Can anybody tell me, how to write the exact curl-command with guzzle?
Thanks

Try using multipart instead of form_params.
http://docs.guzzlephp.org/en/latest/request-options.html#form-params
From Guzzle documentation:
form_params cannot be used with the multipart option. You will need to
use one or the other. Use form_params for
application/x-www-form-urlencoded requests, and multipart for
multipart/form-data requests.
Additionally try setting Guzzle Client with debug on, as it will display raw HTTP request that it sends, so you can compare it more easily with the curl command.
http://docs.guzzlephp.org/en/latest/request-options.html#debug
It is difficult to understand what is the exact request you would like to send, because there is incosistencies between the curl example and your code. I tried to replicate the curl as best as I could. Please note that Request 3rd parameter only expects headers, and for request options you have to use the 2nd parameter of send.
$client = new Client([
'base_uri' => 'https://example.org',
'http_errors' => false
]);
$request = new Request(
'POST',
'/test',
[
'Authorization' => 'Bearer 19237192837129387',
'Content-Type' => 'multipart/form-data',
]
);
$response = $client->send($request, [
'timeout' => 10,
'debug' => true,
'multipart' => [
[
'name' => 'mediaUrl',
'contents' => 'https://myfile.mpg'
],
[
'name' => 'configuration',
'contents' => json_encode([
'speechModel' => [
'language' => 'en-US'
],
'publish' => [
'callbacks' =>
[
[
'url' => 'https://example.org/callback'
]
]
]
])
]
]
]);
