Alice 向 Bob 发送推送通知，而 Bob 的电话是 .inactive 或 .background。 Bob 的手机应该会收到通知并立即触发代码。
问题
这个问题有很多答案，但我能找到的大部分内容都围绕着破解 PushKit 和 CallKit 原生 API 以发送 .voIP 推送。根据这个问题 (iOS 13 not getting VoIP Push Notifications in background)，Apple 不再允许您发送 .voIP 推送而不触发 CallKit 的本机电话响铃例程。
在 iOS 端，我在 AppDelegate.swift 中有以下位
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
registerForPushNotifications()
}
func application(_ application: UIApplication,
didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void)
{
print(">>> I would like this to be triggered even if the app is asleep")
switch application.applicationState {
case .active:
print(">>>>>>> the app is in [FOREGROUND]: \(userInfo)")
break
case .inactive, .background:
print(">>>>>>>> the app is in [BACKGROUND]: \(userInfo)")
break
default:
break
}
}
func registerForPushNotifications() {
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter
.current()
.requestAuthorization(options:[.alert, .sound, .badge]) {[weak self] granted, error in
guard granted else { return }
self?.getNotificationSettings()
}
}
func getNotificationSettings() {
UNUserNotificationCenter.current().getNotificationSettings { settings in
guard settings.authorizationStatus == .authorized else { return }
Messaging.messaging().delegate = self
DispatchQueue.main.async {
// Register with Apple Push Notification service
UIApplication.shared.registerForRemoteNotifications()
/// cache token client side and save in `didRegisterForRemoteNotificationsWithDeviceToken`
if let token = Messaging.messaging().fcmToken {
self.firebaseCloudMessagingToken = token
}
}
}
}
//@Use: listen for device token and save it in DB, so notifications can be sent to this phone
func application(_ application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
if (firebaseCloudMessagingToken != nil){
self.updateMyUserData(
name : nil
, pushNotificationToken: firebaseCloudMessagingToken!
)
}
}
func application(_ application: UIApplication,
didFailToRegisterForRemoteNotificationsWithError error: Error) {
///print(">>> Failed to register: \(error)")
}
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
// @NOTE: this fires when the app is open. So you can go the call screen right away
let payload = notification.request.content.userInfo as! [String:Any?]
let type = payload["notificationType"]
print(">> this fires if the app is currently open")
}
/// @NOTE: we are using backward compatible API to access user notification when the app is in the background
/// @source: https://firebase.google.com/docs/cloud-messaging/ios/receive#swift:-ios-10
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: @escaping () -> Void) {
print(" this fires when the user taps on the notification message")
}
在服务器/Node.js 端，我以这种方式发送推送通知：
// Declare app push notification provider for PushKit
const _ApnConfig_ = {
token: {
key : fileP8
, keyId : "ABCDEFG"
, teamId: "opqrst"
},
production: false
};
var apnProvider = new apn.Provider(_ApnConfig_);
exports.onSendNotification = functions.https.onRequest((request, response) => {
var date = new Date();
var timeStamp = date.getTime();
const deviceTok = "..."
var recepients = [apn.token( deviceTok )]
const notification = new apn.Notification();
notification.topic = "com.thisisnt.working"
notification.body = "Hello, world!";
notification.payload = {
from: "node-apn"
, source: "web"
, aps: {
"content-available": 1
, "data" : { "custom_key":"custom value", "custom_key_2":"custom value 2" }
}
};
notification.body = "Hello, world @ " + timeStamp;
return apnProvider.send(notification, recepients).then(function(res) {
console.log("res.sent: ", res.sent)
console.log("res.failed: ", res.failed)
res.failed.forEach( (item) => {
console.log(" \t\t\t failed with error:", item.error)
})
return response.send("finished!");
}).catch( function (error) {
console.log("Faled to send message: ", error)
return response.send("failed!");
})
})
两者都很标准。我已将content-availabe 设置为1。现在消息正在通过 Apple 推送通知中心显示并显示，它们只是没有按预期触发带有 didReceiveRemoteNotification 的块。
