PUSHER = Grocer.pusher( certificate: "./config/ck.pem",
    passphrase: ENV['grocer_dev_cert_passphrase'],
  gateway: ENV['grocer_pusher_gateway'],
  port: ENV['grocer_pusher_port'],
  retries: 3
  )

FEEDBACK = Grocer.feedback( certificate: "./config/ck.pem" ,
  passphrase: ENV['grocer_dev_cert_passphrase'],
  gateway: ENV['grocer_feedback_gateway'],
  port: ENV['grocer_feedback_port'] ,
  retries: 3
  )
notification = Grocer::Notification.new(
    device_token: "df67fbd000a631998a46289f798beb75249afc2db0c5ecff2cc83db5b0bf245a",
    alert: "This is God",
    badge: 1,
    sound: 'siren.aiff',
    expiry: Time.now + 60*60,
    content_available: true

PUSHER.push(notification)

通过APNS返回警报消息的字节数，但在Heroku中，推送通知尚未显示给相应的设备。请提前帮助我。谢谢。
