Guzzle Not Sending Headers From Form MultiPart - php

Question

I am using "guzzlehttp/guzzle": "~6.0", and trying to post a file to an API endpoint. The file posts fine when using RequestBin but the API is not getting the header it requires. The Header is not sent to Request bin either. According to the docs, I need to do an array of associative arrays. http://docs.guzzlephp.org/en/latest/quickstart.html#post-form-requests
However, this is not working. Here's the Guzzle request:
$client = new GuzzleHttp\Client(['base_uri' => '127.0.0.1:3000']);
$response = $client->request('POST', '/process', [
'multipart' => [
[
'name' => 'file',
'contents' => $file,
'bucketName' => 'test',
'headers' => ['X-API-Key' => 'abc345']
],
]
]);
What am I doing wrong that it's not sending the header?
Thank you very much,
Josh

Answer 1

Headers is an $option, that's mean it must be at the same level as multipart.
<?php
$response = $client->request('POST', '/process', [
'multipart' => [
[
'name' => 'file',
'contents' => 'test',
'bucketName' => 'test',
],
],
'headers' => ['X-API-Key' => 'abc345'] // <------- HERE
]);

You were probably using multipart in conjunction with form_params , this is not explicitly explained in the documentation of laravel but guzzle won't work with both
Note
multipart cannot be used with the form_params 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.
This option cannot be used with body, form_params, or json
To solve this problem you will need to parse all the params to multipart, if you are using laravel or lumen you can do it in this way
if(!empty($this->files))
{
//if there is an image parse all the rest parameters to
// multipart
$file_keys=array_keys($this->files);
foreach($this->files as $k => $file)
{
$http = $http->attach($k, file_get_contents($file),$k);
}
foreach($this->data as $dk =>&$d)
{
if(!in_array($dk,$file_keys))
{
if(is_array($d))
{
$d=json_encode($d);
}
$http = $http->attach($dk,$d);
}
}
return $http=$http->post($this->url);
}
//if there isn't any file just send all as form_params
return $http=$http->post($this->url,$this->data);
