upload video to DailyMotion using GuzzleHttp - php

Question

I'm trying to upload a video using Laravel and GuzzleHttp to DailyMotion. Here's my code:
$file = "3.mp4";
$fields["file"] = fopen($file, 'rb');
$res = $client->post($upload_url, [
'headers' => ['Content-Type' => 'multipart/form-data'],
$fields
]);
$data3 = $res->getBody();
$response_upload_video = json_decode($data3,true);
echo "<br>Getting dm upload video response: ";
print_r($response_upload_video);
$upload_url is a dynamically generated URL passed by DailyMotion. Upon executing the code above, I'll always get this error:
Production.ERROR: GuzzleHttp\Exception\ClientException:
Client error:
POST
http://upload-02.sg1.dailymotion.com/upload?uuid=werewkrewrewrwer&seal=pppppppppppppppp`resulted
in a 400 Bad Request response:
{"error":"invalid content range","seal":"yyyyyyyyyyyyyyyyyy"}
in /home/vagrant/Code/svc-titus/vendor/guzzlehttp/guzzle/src/Exception/RequestException.php:111
But I can upload video to the same upload URL using Postman, as displayed below:

i don't think you need to specify content-type header guzzle will decide it automatically when you provide it a resource also the path of your video here seems problematic if video is stored at public directory you need to use public_path or respective path helper function to get its physical path
below should work in guzzleHttp 6 check sending form files here
http://docs.guzzlephp.org/en/latest/quickstart.html#uploading-data
$file = "3.mp4";
$res = $client->post($upload_url, [
'multipart' => [
[
'name' => 'file',
'contents' => fopen(base_path($file), 'r') // give absolute path using path helper function
]
]
]);
$data3 = $res->getBody();
$response_upload_video = json_decode($data3,true);
echo "<br>Getting dm upload video response: ";
print_r($response_upload_video);
