cURL 將請求 php 發布到 spring

Question

我必須使用 PHP 和 cURL 將文件數組發送到 spring 服務器。

這是彈簧控制器：

@RequestMapping(value = "/upload/teacher" ,method = RequestMethod.POST) 
public HttpStatus uploadFiles(@RequestParam("files") MultipartFile[] inputFiles, 
                              @RequestParam("assignmentID") String assignmentID) throws IOException { ... }

PHP 卷曲：

<?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;

但是使用此代碼，后端不會收到任何內容。

如果我從終端發送 curl 請求，它會起作用：

 curl -F files=@"pathfile1","pathfile2" -F assignmentID="1" http://localhost:8090/upload/teacher

它也適用於郵遞員：

有人能告訴我為什么當我從 php 運行請求時后端沒有收到文件嗎？

如果使用@CrossOrigin注釋 spring 控制器方法會發生什么？

@CrossOrigin
@RequestMapping(value = "/upload/teacher" ,method = RequestMethod.POST) 
public HttpStatus uploadFiles(@RequestParam("files") MultipartFile[] inputFiles, 
                              @RequestParam("assignmentID") String assignmentID) throws IOException { ... }
