Functions

func Listen

func Listen(senderId, apiKey string, h MessageHandler, stop <-chan bool) error

Listen blocks and connects to GCM waiting for messages, calling the handler for CCS message that can be of interest to the listener: upstream messages, delivery receipt notifications, errors. An optional stop channel can be provided to stop listening.

func SendXmpp

func SendXmpp(senderId, apiKey string, m XmppMessage) (string, int, error)

SendXmpp sends a message using the XMPP GCM connection server.

Types

type CcsMessage

type CcsMessage struct {
	From             string `json:"from, omitempty"`
	MessageId        string `json:"message_id, omitempty"`
	MessageType      string `json:"message_type, omitempty"`

	Data             Data   `json:"data,omitempty"`
	ControlType      string `json:"control_type,omitempty"`
}

CcsMessage is an Xmpp message sent from CCS.

type Data

type Data map[string]interface{}

The data payload of a GCM message.

type HttpMessage

type HttpMessage struct {
	To                    string        `json:"to,omitempty"`

	Notification          *Notification `json:"notification,omitempty"`
}

A GCM Http message.

type HttpResponse

type HttpResponse struct {
	MulticastId  int      `json:"multicast_id,omitempty"`
	Success      uint     `json:"success,omitempty"`

	RegistrationId string `json:"registration_id,omitempty"`
	Error          string `json:"error,omitempty"`
}

Result represents the status of a processed Http message.

type XmppMessage

type XmppMessage struct {
	To                       string        `json:"to,omitempty"`
	MessageId                string        `json:"message_id"`
