示例1: waitForNotification
func waitForNotification(l *pq.Listener) {
for {
select {
case notify := <-l.Notify:
payload := strings.SplitN(notify.Extra, "|", 3)
id, err := strconv.ParseInt(payload[0], 10, 64)
if err != nil {
panic(err)
}
var roomId int64
roomId, err = strconv.ParseInt(payload[1], 10, 64)
if err != nil {
panic(err)
}
msg := models.GetMessage(id)
revel.INFO.Printf("received notification with payload: '%d' '%d' '%s' '%s'\n", msg.Id, msg.RoomId, msg.Text, msg.ImageUrl)
Publish(EVENT_MSG, int64(roomId), *msg)
case <-time.After(200 * time.Millisecond):
go func() {
if err := l.Ping(); err != nil {
panic(err)
}
}()
}
}
