Question

我正在尝试通过另一台服务器上的curl上传文件。我已为此创建了一个脚本，但我无法获取$_FILES参数。它是空的。

$request = curl_init('http://localhost/pushUploadedFile.php');
$file_path = $path.$name;
curl_setopt($request, CURLOPT_POST, true);
curl_setopt(
     $request,
     CURLOPT_POSTFIELDS,
     array(
      'file' => '@' . $file_path,
      'test' => 'rahul'
));
curl_setopt($request, CURLOPT_RETURNTRANSFER, true);
echo curl_exec($request);exit();

pushUploadedFile.php：

print_r($_FILES['file']);

Answer 1

您使用的是哪个版本的PHP？在PHP 5.5中引入了curl选项CURLOPT_SAFE_UPLOAD，从PHP 5.6.0开始，它始终默认为true。如果true使用@/path/to/file上传文件被禁用。因此，如果您使用的是PHP 5.6或更高版本，则必须将其设置为false以允许上传：

curl_setopt($request, CURLOPT_SAFE_UPLOAD, false);

但是上传的@/path/to/file格式已经过时并且在PHP 5.5.0之后已弃用，您现在应该使用CurlFile类：

$request = curl_init();
$file_path = $path.$name;
curl_setopt($request, CURLOPT_URL, 'http://localhost/pushUploadedFile.php');
curl_setopt($request, CURLOPT_POST, true);
curl_setopt(
     $request,
     CURLOPT_POSTFIELDS,
     array(
      'file' => new CurlFile( $file_path ),
      'test' => 'rahul'
));
curl_setopt($request, CURLOPT_RETURNTRANSFER, true);
echo curl_exec($request);

Answer 2

// When initialization must be separate from declaration, e.g. class members, 
// initialize with nullptr to make your programming intent explicit.
shared_ptr<Song> sp5(nullptr);
//Equivalent to: shared_ptr<Song> sp5;

        $target_url ="http://www.localwork.com/pushUploadedFile.php";     
        $file_full_path = $path.$img_name;            
        $file_name_with_full_path = new CurlFile($file_full_path, 'image/png', $name);

        $post = array('path' => $path,'file_contents'=>$file_name_with_full_path);
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,$target_url);
        curl_setopt($ch, CURLOPT_POST,1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
        $result=curl_exec ($ch);
        curl_close ($ch);
