node-apn从APN收到InvalidProviderToken (403) response错误。我需要在配置中更改什么才能发送推送消息？
Apple说：APNs supports only provider authentication tokens that are signed with the ES256 algorithm. Unsecured JWTs, or JWTs signed with other algorithms, are rejected, and your provider server receives the InvalidProviderToken (403) response.
