Azure 通知中心，ios 返回“提供的通知负载无效”

Question

Following example Azure Notifications to React Native

Android works, but no matter what payload I pass to SendAppleNativeNotificationAsync I get the same error

Unexpected error sending notification:  The supplied notification payload is invalid

I've even passed a simple string such as this

iOSPayload = "{\"aps\":{\"alert\":\"Notification Hub test notification\"}}"
_hub.SendAppleNativeNotificationAsync(iOSPayload, tags, token)

The escaped quotes seem ok to me, but even with any other combination its not working.

Answer 1

The error may occur if payload is malformed. You may want to know that the standard way to send push notifications is to send, for each notification that is to be sent, a specific payload to platform notification services (WNS, APNS).

For example, to send an alert to APNS, the payload is a JSON object of the following form:

{"aps": {"alert" : "Hello!" }}

When using concatenation, the entire expression must be surrounded with {}

Check this document on Notification Hubs Templates for more details on this.
