cURL post request php to spring - php

Question

I have to send array of a file to a spring server using PHP and cURL.
This is spring controller:
#RequestMapping(value = "/upload/teacher" ,method = RequestMethod.POST)
public HttpStatus uploadFiles(#RequestParam("files") MultipartFile[] inputFiles,
#RequestParam("assignmentID") String assignmentID) throws IOException { ... }
PHP cURL:
<?php
$filenames = array(pathfile1, pathfile2);
$postparameters = array(
'files' => array(
new CURLFile($filenames[0], "text/plain", pathinfo($filenames[0], PATHINFO_BASENAME)),
new CURLFile($filenames[1], "text/plain", pathinfo($filenames[1], PATHINFO_BASENAME))
),
'assignmentID' => "0008"
);
print_r($postparameters);
//init curl
$url = "http://localhost:8090/upload/teacher";
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => $postparameters,
CURLOPT_HTTPHEADER => array(
"Content-Type: multipart/form-data"
),
));
$response = curl_exec($curl);
curl_close($curl);
echo $response;
but with this code the backend does not receive anything.
if I send the curl request from the terminal, it works:
curl -F files=#"pathfile1","pathfile2" -F assignmentID="1" http://localhost:8090/upload/teacher
it also works on postman:

can someone tell me why if the backend does not receive the files when I run the request from php?

What happens if you annotate your spring controller method with #CrossOrigin ?
#CrossOrigin
#RequestMapping(value = "/upload/teacher" ,method = RequestMethod.POST)
public HttpStatus uploadFiles(#RequestParam("files") MultipartFile[] inputFiles,
#RequestParam("assignmentID") String assignmentID) throws IOException { ... }
