- Works with Rails 3 and Ruby 1.9 & 1.8.
- Supports multiple iOS apps.
- Add & remove apps without restarting or affecting the delivery of notifications to other apps.
- Uses a daemon process to keep open persistent connections to the APNs, as recommended by Apple.
- Uses the enhanced binary format so that delivery errors can be reported.
- Records feedback from The Feedback Service.
- Airbrake (Hoptoad) integration.
- Support for dictionary
alert
properties. - Mobile Device Management (MDM)
- Stable. Reconnects to the APNs and your database if connections are lost.
GateGuru, among others!
I'd love to hear if you use rapns - @ileitch on twitter.
Add rapns to your Gemfile:
gem 'rapns'
Generate the migration, rapns.yml and migrate:
rails g rapns
rake db:migrate
-
Open up Keychain Access and select the
Certificates
category in the sidebar. -
Expand the disclosure arrow next to the iOS Push Services certificate you want to export.
-
Select both the certificate and private key.
-
Right click and select
Export 2 items...
. -
Save the file as
cert.p12
, make sure the File Format isPersonal Information Exchange (p12)
. -
If you decide to set a password for your exported certificate, please read the 'Adding Apps' section below.
-
Convert the certificate to a .pem, where
<environment>
should bedevelopment
orproduction
, depending on the certificate you exported.openssl pkcs12 -nodes -clcerts -in cert.p12 -out <environment>.pem
app = Rapns::App.new
app.key = "my_app"
app.certificate = File.read("/path/to/development.pem")
app.environment = "development"
app.password = "certificate password"
app.connections = 1
app.save!
key
is a symbolic name to tie this app to notifications.certificate
is the contents of your PEM certificate, NOT its path on disk.environment
the certificate type, eitherdevelopment
orproduction
.password
should be left blank if you did not password protect your certificate.connections
(default: 1) the number of connections to keep open to the APNs. Consider increasing this if you are sending a large number of notifications to this app.
cd /path/to/rails/app
bundle exec rapns <Rails environment> [options]
-f
--foreground
Prevent rapns from forking into a daemon.-P N
--db-poll N
Frequency in seconds to check for new notifications. Default: 2.-F N
--feedback-poll N
Frequency in seconds to check for feedback. Default: 60.-e
--no-error-checks
Disables error checking after notification delivery. You may want to disable this if you are sending a very high number of notifications.-n
--no-airbrake-notify
Disables error notifications via Airbrake.-p PATH
--pid-file PATH
Path to write PID file. Relative to Rails root unless absolute.-b N
--batch-size N
ActiveRecord batch size of notifications. Increase for possible higher throughput but higher memory footprint. Default: 5000.
n = Rapns::Notification.new
n.app = "my_app"
n.device_token = "934f7a..."
n.alert = "This is the message shown on the device."
n.badge = 1
n.sound = "1.aiff"
n.expiry = 1.day.to_i
n.attributes_for_device = {"question" => nil, "answer" => 42}
n.deliver_after = 1.hour.from_now
n.save!
app
must matchkey
on anRapns::App
.sound
defaults to1.aiff
. You can either set it to a custom .aiff file, ornil
for no sound.expiry
is the time in seconds the APNs (not rapns) will spend trying to deliver the notification to the device. The notification is discarded if it has not been delivered in this time. Default is 1 day.attributes_for_device
is theNSDictionary
argument passed to your iOS app in eitherdidFinishLaunchingWithOptions
ordidReceiveRemoteNotification
.deliver_after
is not required, but may be set if you'd like to delay delivery of the notification to a specific time in the future.
n = Rapns::Notification.new
n.mdm = "magic"
n.save!
Please refer to Apple's documentation (Tables 3-1 and 3-2).
If you signal the rapns process with HUP
it will synchronize with the current Rapns::App
configurations. This includes adding an app, removing and increasing/decreasing the number of connections an app uses.
This synchronization process does not pause the delivery of notifications to other apps.
rapns logs activity to rapns.log
in your Rails log directory. This is also printed to STDOUT when running in the foreground. When running as a daemon rapns does not print to STDOUT or STDERR.
The APNs provides two mechanism for delivery failure notification:
Although rapns makes such errors highly unlikely due to validation, the APNs reports processing errors immediately after being sent a notification. These errors are all centred around the well-formedness of the notification payload. Should a notification be rejected due to such an error, rapns will update the following attributes on the notification and send a notification via Airbrake/Hoptoad (if enabled):
failed
flag is set to true.
failed_at
is set to the time of failure.
error
is set to Apple's code for the error.
error_description
is set to a (somewhat brief) description of the error.
rapns will not attempt to deliver the notification again.
rapns checks for feedback periodically and stores results in the Rapns::Feedback
model. Each record contains the device token and a timestamp of when the APNs determined that the app no longer exists on the device.
It is your responsibility to avoid creating new notifications for devices that no longer have your app installed. rapns does not and will not check Rapns::Feedback
before sending notifications.
Note: In my testing and from other reports on the Internet, it appears you may not receive feedback when using the APNs sandbox environment.
After updating you should run rails g rapns
to check for any new migrations.
Fork as usual and go crazy!
When running specs, please note that the ActiveRecord adapter can be changed by setting the ADAPTER
environment variable. For example: ADAPTER=postgresql rake
.
Available adapters for testing are mysql
, mysql2
and postgresql
.
