PHP - POST request with binary body data - Works with CURL, but not with Laravel

Question

I have below 3rd party API that I am posting images to.

They require that the header's content-type must be set to: Content-Type: image/jpeg, and that the body contains the binary data of the actual image.

Below I am making this request using cURL in PHP - this works fine:

$url = "examle.org/images";
$pathToFile = "myfile.jpeg";
$auth = "Authorization: Bearer <Token>";

$auth = "Authorization: Bearer " . $this->token;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, file_get_contents($pathToFile));
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: image/jpeg', $auth]);
$result = curl_exec($ch);

The above POST using cURL works fine: I get a 200-response success error back. I thought, in order to make it more "Laravel-like", I would use Laravel's HTTP facade (Guzzle):

$post = Http::withHeaders(['Content-Type' => 'image/jpeg'])
          ->withToken("<Token>")
          ->attach('file', file_get_contents($pathToFile), 'myfile.jpeg')
          ->post($url);

The above does not work as expected. The 3rd party API services return a 400 response and tells me that it cannot read the image file.

What am I doing wrong?

Answer 1

I would try withBody

$post = Http::withBody(file_get_contents($pathToFile), 'image/jpeg')
      ->withToken("<Token>")
      ->post($url);
