senekis/pushmeup

This gem is a wrapper to send push notifications to devices. Currently it only sends to Android or iOS devices, but more platforms will be added soon. With APNS (Apple Push Notifications Service) you can send push notifications to Apple devices. With GCM (Google Cloud Messaging) you can send push notifications to Android devices.

Pushmeup

a gem for various push notification services.

Goals

Pushmeup is an attempt to create an push notifications center that could send push to devices like:

• Android
• iOS
• Mac OS X
• Windows Phone
• And many others

Currently we have only support for iOS and Android but we are planning code for more plataforms.

Installation

$ gem install pushmeup

or add to your Gemfile

gem 'pushmeup'

and install it with

$ bundle install

APNS (Apple iOS)

Configure

1. In Keychain access export your certificate and your private key as a p12.


2. Run the following command to convert the p12 to a pem file

    $ openssl pkcs12 -in cert.p12 -out cert.pem -nodes -clcerts
   

3. After you have created your pem file. Set the host, port and certificate file location on the APNS class. You just need to set this once:

    APNS.host = 'gateway.push.apple.com' 
    # gateway.sandbox.push.apple.com is default and only for development
    # gateway.push.apple.com is only for production
    
    APNS.port = 2195 
    # this is also the default. Shouldn't ever have to set this, but just in case Apple goes crazy, you can.
    
    APNS.pem  = '/path/to/pem/file'
    # this is the file you just created
    
    APNS.pass = ''
    # Just in case your pem need a password
   

Usage

Sending a single notification:

device_token = '123abc456def'
APNS.send_notification(device_token, 'Hello iPhone!' )
APNS.send_notification(device_token, :alert => 'Hello iPhone!', :badge => 1, :sound => 'default')

Sending multiple notifications

device_token = '123abc456def'
n1 = APNS::Notification.new(device_token, 'Hello iPhone!' )
n2 = APNS::Notification.new(device_token, :alert => 'Hello iPhone!', :badge => 1, :sound => 'default')
APNS.send_notifications([n1, n2])

All notifications passed as a parameter will be sent on a single connection, this is done to improve reliability with APNS servers.

Another way to send multiple notifications is to send notifications in a persistent connection (thread safe)

# Define that you want persistent connection
APNS.start_persistence

device_token = '123abc456def'

# Send single notifications
APNS.send_notification(device_token, 'Hello iPhone!' )
APNS.send_notification(device_token, :alert => 'Hello iPhone!', :badge => 1, :sound => 'default')

# Send multiple notifications
n1 = APNS::Notification.new(device_token, 'Hello iPhone!' )
n2 = APNS::Notification.new(device_token, :alert => 'Hello iPhone!', :badge => 1, :sound => 'default')
APNS.send_notifications([n1, n2])

...

# Stop persistence, from this point each new push will open and close connections
APNS.stop_persistence

Sending more information along

APNS.send_notification(device_token, :alert => 'Hello iPhone!', :badge => 1, :sound => 'default', 
                                    :other => {:sent => 'with apns gem', :custom_param => "value"})

this will result in a payload like this:

{"aps":{"alert":"Hello iPhone!","badge":1,"sound":"default"},"sent":"with apns gem", "custom_param":"value"}

Getting your iOS device token

- (void)applicationDidFinishLaunching:(UIApplication *)application {
    // Register with apple that this app will use push notification
    ...
    
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeBadge)];
    
    ...
    
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // Show the device token obtained from apple to the log
    NSLog("deviceToken: %", deviceToken);
}

GCM (Google Cloud Messaging)

Configure

	GCM.host = 'https://android.googleapis.com/gcm/send'
	# https://android.googleapis.com/gcm/send is default

	GCM.format = :json
	# :json is default and only available at the moment

	GCM.key = "123abc456def"
	# this is the apiKey obtained from here https://code.google.com/apis/console/

Usage

Sending a single notification:

	destination = ["device1", "device2", "device3"]
	# can be an string or an array of strings containing the regIds of the devices you want to send

	data = {:key => "value", :key2 => ["array", "value"]}
	# must be an hash with all values you want inside you notification

	GCM.send_notification( destination )
	# Empty notification

	GCM.send_notification( destination, data )
	# Notification with custom information

	GCM.send_notification( destination, data, :collapse_key => "placar_score_global", :time_to_live => 3600, :delay_while_idle => false )
	# Notification with custom information and parameters

for more information on parameters check documentation: GCM | Android Developers

Sending multiple notifications:

	destination1 = "device1"
	destination2 = ["device2"]
	destination3 = ["device1", "device2", "device3"]
	# can be an string or an array of strings containing the regIds of the devices you want to send

	data1 = {:key => "value", :key2 => ["array", "value"]}
	# must be an hash with all values you want inside you notification
	
	options1 = {:collapse_key => "placar_score_global", :time_to_live => 3600, :delay_while_idle => false}
	# options for the notification
	
	n1 = GCM::Notification.new(destination1, data1, options1)
	n2 = GCM::Notification.new(destination2, data2)
	n3 = GCM::Notification.new(destination3, data3, options2)

	GCM.send_notifications( [n1, n2, n3] )
	# In this case, every notification has his own parameters

for more information on parameters check documentation: GCM | Android Developers

Getting your Android device token (regId)

Check this link GCM: Getting Started

(Optional) You can add multiple keys for GCM

You can use multiple keys to send notifications, to do it just do this changes in the code

Configure

	GCM.key = { :key1 => "123abc456def", :key2 => "456def123abc" }
	# the ``:key1`` and the ``:key2`` can be any object, they can be the projectID, the date, the version, doesn't matter.
	# The only restrain is: they need to be valid keys for a hash.

Usage

	# For single notification
	GCM.send_notification( destination, :identity => :key1 )
	# Empty notification

	GCM.send_notification( destination, data, :identity => :key1 )
	# Notification with custom information

	GCM.send_notification( destination, data, :collapse_key => "placar_score_global", :time_to_live => 3600, :delay_while_idle => false, :identity => :key1 )
	# Notification with custom information and parameters

	# For multiple notifications
	options1 = {}
	options2 = {..., :identity => :key2}
	n1 = GCM::Notification.new(destination1, data1, options1.merge({:identity => :key2}))
	n2 = GCM::Notification.new(destination2, data2, :identity => :key1)
	n3 = GCM::Notification.new(destination3, data3, options2)

	GCM.send_notifications( [n1, n2, n3] )
	# In this case, every notification has his own parameters, options and key
