Silent push notification not working in ios 13

问题

Silent notification is not working in iPadOS. But, in 12.4 OS it is working fine.

{ "aps": { "content-available" : "1" }, "BuildingId":13, "NotificationTypeId":214, "CustomerName":"Test", "Amount":"6778", "CustomerID":32752, "Environment":"TEST", "Title":"" }

回答1:

Adding "apns-push-type" header field solved the issue. Please note this is a APNS POST request header field, not a new key in push JSON.

回答2:

"apns-push-type" is Required when delivering notifications to devices running iOS 13 and later, or watchOS 6 and later. Ignored on earlier system versions. Apple document APNS Silent push notification.
