How to use PHP cURL to send images with the correct Content
Objective:
I want to send multiple images using multipart/form-data. Below is a snippet of my code.
Problem:
On one PC, the multipart attachment is sent by the correct MIME header Content-Type: image/jpeg, but on another PC, the MIME header is Content-Type: application/octet.
Question:
How can I force cURL to set the correct Content-Type header for the MIME content?
$ch = curl_init();
$params = array('name' => '@D:globe.jpg');
$base_url = "https://example.com"."?".varEncode($test_data);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_VERBOSE, TRUE);
curl_setopt($ch, CURLOPT_URL,$base_url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
Use the CURLOPT_HTTPHEADER option:
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: image/jpeg"));
So specify Content-Type headers specifically for file uploads, use:
$params = array('name'=>'@D:globe.jpg;type=image/jpeg');
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
