Dropbox api file download and upload to s3 [duplicate]

im trying to download the file from dropbox using v2 api and upload it to amazon s3

to download file here is what i did:

$headers= array( 'Content-Type: ', "Authorization: Bearer EkOrS5mbVAwA....", "Dropbox-API-Arg: {\"path\": \"/clients/erbrecht, kenneth/2nd dispute erbrecht.docx\"}"); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'https://content.dropboxapi.com/2/files/download'); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_POST, 1); //curl_setopt($ch, CURLOPT_POSTFIELDS,json_encode($data)); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response = curl_exec($ch); curl_close($ch); 

the code above returned response in "application/octet-stream" i assume, so my first problem is to convert this stream to a file and upload it to s3

i have this code that takes physical path of the file and upload it to s3 but in the above case i have the stream

try{ $s3 = Aws\S3\S3Client::factory(array( 'region' => S3_REGION, 'version' => 'latest', 'credentials' => array( 'key' => S3_ACCESS_KEY, 'secret' => S3_SECRET_KEY, ) )); $s3->putObject([ 'Bucket' => $this->s3bucket, 'Key' => "uploads/{$name}", 'Body' => fopen($path,'rb'), 'ACL' => 'public-read' ]); return ''; }catch(S3Exception $e){ //return $e->getMessage(); return 'Error Uploading File, Please try again'; } 

so the problem is to convert stream to file and upload to s3, how can i change the above code to do that

Thanks in advance.
