后台模式的静默通知不起作用 iOS

Question

我正在使用 One Signal 接收通知。 Xcode.

上的原生 Swift 4.2

我需要向我的应用程序发送静默通知，只是为了更新数据。我不想打扰用户。

好的，我可以在前台执行此操作。但是我不能在后台。

我正在 One Signal 网站上测试的一些代码：

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                     fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {

        if let aps = userInfo["aps"] as? NSDictionary {
            if let alert = aps["alert"] as? NSDictionary {
                if let body = alert["body"] as? NSString {
                    print(body)
                    if body.isEqual(to: "Pedido") {
                        let strdata = PedidoDAO().getMostRecentDtPedido()
                        // >>>>>>> It works perfectly on FOREGROUND mode, without showing any notification, sound, or banner.**
                        self.loadOrdersFromLastSyncByApi(strdata)
                    }
                }
            }
        }

部分配置：

let onesignalInitSettings = [kOSSettingsKeyAutoPrompt: false, kOSSettingsKeyInAppAlerts: false, kOSSettingsKeyInAppLaunchURL: false]

        OneSignal.initWithLaunchOptions(launchOptions,
                                        appId: "yyyyyyyyy-zzzzz-hhhhh-gggg-xxxxxxxxxxxx",
                                        handleNotificationAction: {
                                            (result) in

                                            let payload = result?.notification.payload

                                            if let additionalData = payload?.additionalData {

                                                print("payload")
                                                //  >>>>>>> when app is on BACKGROUND, the notification comes and when I click on it, I can see the additional data. But I dont want to make user click on it.
                                                print(additionalData)
                                            }
                                        },
                                        settings: onesignalInitSettings)

        OneSignal.inFocusDisplayType = OSNotificationDisplayType.none;

        OneSignal.promptForPushNotifications(userResponse: { accepted in
            print("User accepted notifications: \(accepted)")
        })

我也可以在 Postman 上测试。它在前台模式下完美运行，但仅显示带有“。”的烦人通知。在背景模式下的横幅上：

https://onesignal.com/api/v1/notifications
Headers:
Authorization: Basic MY_REST_API_ONE_SIGNAL
Content-Type: application/json

Body raw:
{
  "app_id": "yyyyyyyyy-zzzzz-hhhhh-gggg-xxxxxxxxxxxx",
  "include_player_ids": ["MY_TEST_IPHONE_ID_"],
  "data": {"Pedido": "000"},
  "content-available" : true,
  "contents": {"en": "."}
}

我不知道是否可以不在后台显示通知，但强制用户单击它来更新数据对我来说没有意义。请问有人有解决方案或其他想法吗？

Answer 1

从 OneSignal 的 API 文档来看，您的推送负载应该是

{
  "app_id": "yyyyyyyyy-zzzzz-hhhhh-gggg-xxxxxxxxxxxx",
  "include_player_ids": ["MY_TEST_IPHONE_ID_"],
  "data": {"Pedido": "000"},
  "content_available" : true
}

注意 content_available 中的“_”。
