Sends a push notifications to an iOS and an Android device from Amazon SNS V2
require 'rubygems'
require 'aws-sdk'
# This code snippet sends a push notification to a device using the Amazon SNS service.
#
# It is using the preview V2 amazon gem as per:
# https://aws.amazon.com/sdk-for-ruby/
#
# This was installed using:
# $ gem install aws-sdk --pre
#
# Refer to gem doc:
# http://docs.aws.amazon.com/sdkforruby/api/Aws/SNS/Client.html
#
# SNS was set up in:
# http://console.aws.amazon.com/sns/home
#
# ie. we first set up a GCM, an APNS_SANDBOX and an APNS app in the AWS SNS dashboard.
#
# This guide helped with configuring the iOS apps:
# http://www.adventuresofanentrepreneur.net/creating-a-mobile-appsgames-company/setting-up-aws-sns-to-send-push-notifications-to-ios-devices
#
# Note: In the code below, we are using an IAM user instead of the root Amazon account for this access key and
# secret access key authorization for security purposes.
#
# Refer:
# http://docs.aws.amazon.com/IAM/latest/UserGuide/ManagingCredentials.html
# http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSGettingStartedGuide/AWSCredentials.html
#
# ie.
# 1/ Navigate to:
# https://console.aws.amazon.com/iam/home
#
# 2/ Go to 'Groups' and create a new group and select 'Amazon SNS Full Access'
#
# 3/ Go to 'Users' and create a user and associate the group you created
#
# 4/ Click 'Create Access Key' and 'Download Credentials'. Secret key will not be available again so make sure to make a copy of it.
