Chapter 6. APNS
Apns Component Copier lienLien copié sur presse-papiers!
Copier lienLien copié sur presse-papiers!
Available as of Camel 2.8
The apns component is used for sending notifications to iOS devices. The apns components use javapns library. The component supports sending notifications to Apple Push Notification Servers (APNS) and consuming feedback from the servers.
The consumer is configured with a default polling time of 3600 seconds. It is advisable to consume the feedback stream from Apple Push Notification Servers regularly at larger intervals to avoid flooding the servers.
The feedback stream gives information about inactive devices. This information can be consumed infrequently (every two or three hours) if your mobile application is not heavily used.
Maven users will need to add the following dependency to their
pom.xml
for this component:

When Camel fetches feedback data corresponding to inactive devices, it retrieves a List of InactiveDevice objects. Each InactiveDevice object on the retrieved list will be set as the In body, and then processed by the consumer endpoint.
Message Headers Copier lienLien copié sur presse-papiers!
