Hello, I’m trying to send a file through the API response and download it using Guzzle for a web app project, the problem is that when I try to save the file the size is always 0 bytes. Is this approach missing something?
API Code
if ($document[0]->exists) {
$payload[] = $document[0]->fileOutput();
$file = $document[0]->file_url;
$openFile = fopen($file, 'rb');
$stream = new \Slim\Http\Stream($openFile);
return $response->withStatus(200)
->withHeader('Content-Type', 'application/force-download')
->withHeader('Content-Type', 'application/octet-stream')
->withHeader('Content-Type', 'application/download')
->withHeader('Content-Description', 'File Transfer')
->withHeader('Content-Transfer-Encoding', 'binary')
->withHeader('Content-Disposition', 'attachment; filename="' . basename($file) . '"')
->withHeader('Expires', '0')
->withHeader('Content-Length', filesize($file))
->withHeader('Cache-Control', 'must-revalidate')
->withHeader('Pragma', 'public')
->withBody($stream)
->withJson([
'message' => 'Success',
'code' => 204,
'documents' => $payload
]);
} Web App Code
public function requestFile($path)
{
$credentials = BaseMiddleware::getToken();
try {
$this->api_response = $this->client->get(
$this->api_address . $path, [
'headers' => [
'Authorization' => 'Bearer ' . $credentials
],
]);
} catch (ServerException $server_exception) {
$this->api_response = $server_exception;
} catch (ClientException $client_exception) {
$this->api_response = $client_exception;
} catch (BadResponseException $response_exception) {
$this->api_response = $response_exception;
}
return $this->api_response;
} public function requestDocumentAttachment($request, $response, $args)
{
$path = "/documents/" . $args['document_id'] . '/attachment';
$api_request = $this->requestFile($path);
if (method_exists($api_request, 'getCode')) {
$result = $api_request;
$result_code = $result->getCode();
} else {
$result = $api_request->getBody()->getContents();
$result_code = json_decode($result)->code;
}
if ($result_code == 204) {
// need to figure out how to download file correctly, currently the download size is zero.
return $api_request;
} else if ($result_code == 500) {
$_SESSION['result_error'] = "Invalid request, try again";
} else if ($result_code == 401) {
$_SESSION['result_error'] = "Not authorized";
}
