Notnoop/java-apns Github:https://github.com/notnoop/java-apns Introduction
Java-apns is a Java client that serves the APNs service, which is designed to provide a highly scalable, simple, modular interface to the Apple server.
These interfaces require very little code to do most of the cases, and you can also reconfigure the Java-apns library with your own network link library or JSON library.

Apns is a message push mechanism for iOS. For more information, see the final reference list. Here we emphasize some key steps.
1. Generate a certificate.
Interacting with Apple's apns server involves iOS devices and providers that provide push services. Both require certificate verification. IOS devices interact with apns through the underlying layer, and applicationsProgramYou do not need to refere

principle
To put it simply, the app has to dynamically update the message on its own, one of which is polling, which brings additional traffic to the user. Another scenario is for the Push,app client and server to keep a long connection directly, with new messages when the server push to the app client.
Both of these "push" implement
Simply say the implementation of Apple Notification Push Service (APNS) client some of the areas to note:
Use long connections;
Sanbox server is useless, debugging directly with the "gateway.push.apple.com" domain name;
For the wrong notification,
A set of APNs push platform developed in the previous period is very inefficient, and through the further study of Apple's message push service, summed up a lot of experience. At the same time also referred to some of the online technology blog blog, to complete the previous written a PHP class, the code is as follows:
The code is as follows

Just a few things to note about implementing the Apple Notification Push Service (APNs) client:
Use long connections;
Sanboxserver is useless, debugging directly with the "gateway.push.apple.com" domain name;
For the wrong notification.
Get the failed push token from the feedback server of Apple apns, apnsfeedback
When developing your own apple PUSH Service, you must properly control the tokens of ios devices. This Token is generated by the Apns server on the
test in a simple way );
2. The obtained token is added with the feedback service when the last push failed to your application. The specific time of the failure will be returned.
3. The returned data is composed of three parts. See the figure below.
The structure contains three parts: The first part is the timestamp of the last

Feedback Service
Apple also provides a feedback service that
