JSON-RPC 2.0 允许通知有一个错误响应？
JSON-RPC 2.0 allow Notifications to have an Error response?
阅读 JSON-RPC 2.0 规范后，我仍然不能 100% 确定：规范是否允许通知的发送者能够接收回错误对象？例如，如果 Notification 的接收者未能解析 Notification 的有效载荷，它是否可以回复说它解析失败？甚至不允许？
如果允许，那么错误对象响应是否需要 "id": null 或不存在？
谢谢。

是的，如果它不是有效的 JSON-RPC 请求，您应该以错误响应。
If there is not enough progression through the process to determine that the
request object is a notification, it should default to normal request
handling, which would include sending a response... which probably is also
always an error.
至于你问题的第二部分，是的，你必须包括"id": null。
id
This member is REQUIRED.
If there was an error in detecting the id in the Request object (e.g. Parse error/Invalid Request), it MUST be Null.
