我使用的是REST API的V2。此代码在旧版本的WordPress和WooCommerce上运行良好。我无法将图像上传到产品。
升级后我得到的第一个错误是：

array (
  'code' => 'woocommerce_product_image_upload_error',
  'message' => 'Invalid image: Sorry, this file type is not permitted for security reasons.',
  'data' => 
  array (
    'status' => 400,
  ),

通过将wp-config.php中的以下内容添加到文件底部解决：

define('ALLOW_UNFILTERED_UPLOADS', true);

第二个错误，我不能弄清楚。图像不会上传，并留下一个鬼图像的地方上传。
