Payload
Optional. If you are including a payload in the message, you use the
data parameter to include your custom key/value pairs. The client app
handles the data payload for display or other processing purposes.
The notification parameter with predefined options indicates that GCM
will display the message on the client app’s behalf if the client app
implements GCMListenerService on Android, or if the notification
message is sent to an iOS device. This applies for both HTTP and XMPP.
The app server can send a message including both notifications and
data payloads. In such cases, GCM handles displaying the notification
payload and the client app handles the data payload.
See the Server Reference for details on sending and receiving
messages.

使用场景
Notification: GCM automatically displays the message to end user devices on behalf of the client app. Notifications have a pre-defined set of user-visible keys.
Data: Client app is responsible for processing data messages. Data messages have only custom key/value pairs.
如何发送
Notification: Set notification payload. May have optional data payload. Always collapsible.
Data: Set data payload only. Can be either collapsible or non-collapsible.
