Safari Notifications not getting delivered using Pushy Library

[Jai Vaswani]

Hi,
I am using Pushy 0.9.3 for sending Push Notifications.
For sending push notification to IPhone device it is absolutely working fine. But, Safari the notifications on Mac are not getting delivered.
Although the code prints success while sending push notification on Safari, it is never delivered.

To cross check if the inputs were correct, I  tried using php-apns library and the safari notifications were delivered on my Mac.


I went through this issue  where someone tried the same and in the comments it was mentioned -

Connecting to api.push.apple.com works fine, but apnsClient.connect("gateway.push.apple.com", 2195) I want to use Pushy for sending safari notification gives the following exception. gateway.push.apple.com is the old binary-streaming server and does not support HTTP/2.

Also at developer.apple  it is mentioned -

Pushing Notifications

You send push notifications to clients in the same way that iOS and OS X apps push notifications to APNs. As a push notification provider, you communicate with APNs over a binary interface. This a high-speed, high-capacity interface uses a streaming TCP socket design with binary content. The binary interface is asynchronous.

The binary interface of the production environment is available through gateway.push.apple.com, port 2195. Do not connect to the development environment to send Safari Push Notifications. You may establish multiple parallel connections to the same gateway or to multiple gateway instances.

My concern is how do I use Pushy Library to Send Safari Notification ? Does Pushy Library really support sending Safari Notifications ?
If not, any other alternative library or working java code would be a great help.

Thanks.

Pushy went to the HTTP/2 interface for APNS in 0.5 so you will need to drop back, I believe, to 0.4.3 for binary interface support.  My head explodes that Safari push is not available via the much better HTTP/2 protocol.  Although reading through the safari push doc, Apple dealt with the crappy error reporting on the binary interface with a log-back interface to the web server.

Best of luck,

Are you certain that the HTTP/2 API won't deliver Safari push notifications? My understanding is that is *should* work, and maybe the docs are a little outdated. I'm reasonably confident other users have had success with the HTTP/2 API; can anybody on the list confirm that's the case?

Pushy is an open-source Java library for sending APNs (iOS and OS X) push notifications. Pushy is brought to you by the engineers at RelayRides.

Thanks a lot Kenneth.
I am able to send Safari notifications via Pushy 0.4.3 and they are successfully delivered.
The only problem that I faced is the payload creation. payloadBuilder.setAlertTitle("Title") doesn't add the title inside the payload and also there is no provision for adding url-args.
I managed to create the desired payload string and it works fine for me.

[Jai Vaswani]

Yes I am pretty sure that Safari notifications are delivered only through binary interface. It works using Pushy 0.4.3 but doesn't works with 0.9.3 .
Can't we have support for the old binary interface in the upcoming versions??
As I am already using 0.9.3 for sending IOS notifications in my application, Now I will have to create a separate application for sending Safari notifications through 0.4.3 .

Folks, I've received confirmation that Safari push notifications SHOULD work via the HTTP/2 APNs API. Further, I've received confirmation that the Safari push notification docs are simply out of date.

Hope that helps!
