apns-ruby
This gem sends APNS notifications with proper error handling. Most importantly, it does this without all the nonsense other gems provide:
- Storing notifications in a database, and have a separate process consume them. Worse, only a single consumer is ever allowed.
- Opening a new SSL connection for every notification, which typically takes several hundred milliseconds. Imagine how long it would take to send a million notifications.
Example usage:
pem = path_to_your_pem_file
host = 'gateway.sandbox.push.apple.com' # or 'gateway.push.apple.com' on production
token = a_valid_apns_device_token
conn = APNS::Connection.new(pem: pem, host: host)
conn.error_handler = ->(code, notification) {
case code
when 8
if notification.nil?
puts "Insufficient buffer size to collect failed notifications, please set a larger buffer size when creating an APNS connection."
return
end
puts "Invalid token: #{notification.device_token}"
# Handle the invalid token per Apple's docs
else
# Consult Apple's docs
end
}
n1 = APNS::Notification.new(token, alert: 'hello')
ne = APNS::Notification.new('bogustoken', alert: 'error')
n2 = APNS::Notification.new(token, alert: 'world')
conn.push([n1, ne, n2])
# Should receive only a 'hello' notification on your device
# Wait for Apple to report an error and close the connection on their side, due to
# the bogus token in the second notification.
# We'll detect this and automatically retry and invoke your error handler.
sleep(7)
conn.push([APNS::Notification.new(token, alert: 'hello world 0')])
sleep(7)
conn.push([APNS::Notification.new(token, alert: 'hello world 1')])
# 'Invalid token: bogustoken' is printed out
# We should be receiving each and every successful notification with texts:
# 'world', 'hello world 0', and 'hello world 1'.
