Curl Not Working in WordPress

I am facing an issue with uploading a file on another server using curl in wordpress, the code simply works outside wordpress, but when i use in a wordpress template then it throws an error “Error: couldn’t open file C:\wamp64\tmp\phpAFFB.tmp”
I have wamp installed and apache maven which is having one java project, there is an api which allows me to upload file on this url “https://localhost:8080/fileupload/?projectName=project” which returns some string through which i identify that file has been uploaded.

$tmpfile  = $_FILES['cvs_file']['tmp_name'];
$filename = basename($_FILES['cvs_file']['name']); 
$filetype = $_FILES['cvs_file']['type']; 

	$post_data = array(
   'uploadingFiles' => curl_file_create($tmpfile, $filetype, $filename)
	);

$curl_handle = curl_init("https://localhost:8080/fileupload/?projectName=project");  
curl_setopt($curl_handle, CURLOPT_POST, 1);
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, $post_data); 
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_handle, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl_handle, CURLOPT_SSL_VERIFYPEER,FALSE);
$returned_data = curl_exec($curl_handle);
if( $returned_data === false ){
	echo "Error: ". curl_error($curl_handle);
}
die;

curl_close ($curl_handle);

I have tried with wp_remote_post as well but file upload is not working, any help ?
