/attachable端点用于链接现有附件到对象，而Content-Type是：

• application/json

文档在这里：https://developer.intuit.com/app/developer/qbo/docs/develop/tutorials/attach-images-and-notes#attaching-a-note-to-an-object

/upload终结点用于上传新附件，Content-Type是：

• multipart/form-data

文档：https://developer.intuit.com/app/developer/qbo/docs/develop/tutorials/attach-images-and-notes#uploading-files-to-the-attachment-list
