如何使用Fuel

Question

尝试使用Fuel将图像发送到服务器时出现问题。 我正在尝试使用Fuel.upload方法。

        Fuel.upload(urlfile).source { request, url ->
            File(photopath)
        }.responseString { request, response, result ->

        }

图片类似于：/storage/emulated/0/Android/data/fr.tais.riodi/files/Pictures/MyPicture4945313277123614993.jpg

$target_dir = "images/";
$target_file_name = $target_dir .basename($_FILES["file"]["name"]);
$response = array();

// Check if image file is a actual image or fake image
if (isset($_FILES["file"])) 
{
   if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_file_name)) 
   {
     $success = true;
     $message = "Successfully Uploaded";
   }
   else 
   {
      $success = false;
      $message = "Error while uploading";
   }
}
else 
{
      $success = false;
      $message = "Required Field Missing";
}
$response["success"] = $success;
$response["message"] = $message;
echo json_encode($response);

我试图找到此操作的示例。你有例子或想法吗？

谢谢
