https://onesignal.com/api/v1//notifications：http.DefaultTransport和http.DefaultClient在App Engine中不可用

当我试图在golang App Engine中使用onesignal enviorment实现推送通知时，但iam出错“http.DefaultTransport和http.DefaultClient不是在App Engine中可用”。这是我的代码，https://onesignal.com/api/v1//notifications：http.DefaultTransport和http.DefaultClient在App Engine中不可用

func (c *PushNotificationController) CreateNotification() { 
    client := onesignal.NewClient(nil) 
    client.AppKey = "MyAppKey" 
    client.UserKey = "MyUserKey" 
    notifID := CreateNotifications(client) 
    log.Println(notifID) 
} 

func CreateNotifications(client *onesignal.Client) string { 
    playerID := "SamplePlayerId" // valid 
    notificationReq := &onesignal.NotificationRequest{ 
     AppID:   "MyAppKey", 
     Contents:   map[string]string{"en": "English message"}, 
     IsIOS:   true, 
     IncludePlayerIDs: []string{playerID}, 
    } 
    if createRes, res, err := client.Notifications.Create(notificationReq){ 
     if err != nil { 
      log.Fatal(err) 
     } 
     return createRes.ID 
    } 
    ... 
}
