Upload File Via PHP Curl PUT - php

Question

Having quite a bit of trouble PUT-ting a PDF. I've managed to get it working fine in Postman, using the code below (large code block) and appending the PDF via the body as form-data. I'm trying to replicate this in PHP now. I'm having trouble attaching the PDF though.
I've tried numerous techniques trying to attach the PDF via "CURLOPT_INFILE", "CURLOPT_POSTFIELDS" to no avail.
I create the file via:
$pdf = $_SERVER['DOCUMENT_ROOT'] . '/pdf/temp/temp.pdf';
$file = curl_file_create($pdf, 'application/pdf', 'receipt');`
or
$file = new CURLFile($pdf, 'application/pdf', 'receipt');
I've tried using:
$file = fopen($pdf, 'rb');
$file = array('file' => $file);
CURLOPT_POSTFIELDS => $file,
CURLOPT_INFILESIZE => $fileSize,
CURLOPT_INFILE => $file
No luck though.
<?php
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://staging-tallie.com/v2/enterprise/ENTERPRISEID/MyReceipt/",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "PUT",
CURLOPT_POSTFIELDS => "-----011000010111000001101001\r\nContent-Disposition: form-data; name=\"file\"\r\n\r\n\r\n-----011000010111000001101001--",
CURLOPT_HTTPHEADER => array(
"accept: application/json; charset=utf-8",
"cache-control: no-cache",
"content-type: multipart/form-data; boundary=---011000010111000001101001",
"token: TOKEN",
"upload-filename: receipt.pdf"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
Error reads:
<?xml version="1.0" encoding="utf-8"?>
<ErrorResponse xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ResponseCode>400</ResponseCode>
<Message>Unable to Save the file to the Storage Service.</Message>
</ErrorResponse>

Answer 1

400 is an HTTP response code indicating that the request was impossible to satisfy. That, along with the accompanying message text, suggest that the PHP process does not have write access to the destination directory.

Answer 2

This code worked for me in order to upload a file to bluemix Cloud Object Storage. File is uploaded from temporary folder after form submit using PUT method. Don't forget to validate file mime and extension before upload.
if (is_uploaded_file($_FILES['my_file']['tmp_name'])){
$ch = curl_init();
$url = IBM_BLUEMIX_BUCKET_END_POINT.$bucket_name."/".$file_name; // give the file a unique name
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_PUT, true); //PUT REQUEST
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'x-amz-acl: public-read', //header required for bluemix
'Authorization: Bearer '.$access_token, // authorization for bluemix iam
'Content-Type: '.$conten_type, //application/pdf or image/jpg
'Expect: '
));
$image_or_file = fopen($_FILES['my_file']['tmp_name'], "rb");
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($ch, CURLOPT_INFILE, $image_or_file);
curl_setopt($ch, CURLOPT_INFILESIZE, $_FILES[$fieldName]['size']);
curl_setopt(
$ch,
CURLOPT_POSTFIELDS,
array(
'file' =>
'#' . $_FILES['my_file']['tmp_name']
. ';filename=' . $_FILES['my_file']['name']
. ';type=' . $conten_type //application/pdf or image/jpg
));
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT ,16);
curl_setopt($ch,CURLOPT_TIMEOUT, 20);
curl_setopt($ch, CURLINFO_HEADER_OUT, true); // enable tracking
$response = curl_exec($ch);
$headerSent = curl_getinfo($ch ); // request headers from response (check if something wrong)
curl_close ($ch);
fclose($image_or_file);
if(!$response){ // or response
// do something...
}
}else{
//File did not upload, do something ...
}
