Curl POST上传文件请求返回false

Question

I'm trying to use the gfycat API to create a gfycat with a file upload through curl with php but it doesn't work and var_dump($response) gives me bool(false).

My Code:

$file_path = $target_dir.$newfilename;
$cFile = curl_file_create($file_path);
$data = array(
     "file" => $cFile,
);
$target_url = "https://filedrop.gfycat.com";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $target_url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
     "Content-Type: multipart/form-data"
));            

$response = curl_exec($ch);
var_dump($response); // bool(false) here

curl_close($ch);

Help would be really appreciated. Thanks.

Btw I got it to work with this:

$file_path = "ABSOLUTE_FILE_PATH".$newfilename;
$cFile = curl_file_create(realpath($file_path));
$data = array(
"key" => $newfilename,
"file" => $cFile,
);
$target_url = "https://filedrop.gfycat.com";

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_URL, $target_url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Content-Type: multipart/form-data"
));

$response = curl_exec($ch);

curl_close($ch);
