Firebase 推送通知不适用于 iOS

Question

我想使用 Firebase 云消息传递实现推送通知

我已经按照说明设置了我的项目并上传了 APN 证书 并且我正在使用fcmtoken向我的真实设备发送测试消息

我的配置在应用程序代表中如下

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
registerForPushNotifications(app: application)
return true
}
func registerForPushNotifications(app: UIApplication) {
UNUserNotificationCenter.current().delegate = self
Messaging.messaging().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(options: authOptions) { (authorized, error) in
if let error = error {
print(error.localizedDescription)
return
}
if authorized {
print("authorized")
DispatchQueue.main.async {
UIApplication.shared.registerForRemoteNotifications()
}
} else {
print("denied")
}
}
app.registerForRemoteNotifications()
}
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Firebase registration token: (fcmToken)")
let dataDict:[String: String] = ["token": fcmToken]
NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
// TODO: If necessary send token to application server.
// Note: This callback is fired at each app startup and whenever a new token is generated.
}
func application(_ application: UIApplication,
didReceiveRemoteNotification notification: [AnyHashable : Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
print("notofication arrivied")
if Auth.auth().canHandleNotification(notification) {
completionHandler(.noData)
return
}
// This notification is not auth related, developer should handle it.
}

它应该看到notofication arrivied但它没有也设置了一个喙点似乎这部分从未被原谅，因此消息不会到来

Answer 1

除非您启用了重排，否则我在您的应用程序代表中看不到此内容

func application(application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
Messaging.messaging().apnsToken = deviceToken
}

此代码将您的 APNs 设备令牌映射到 FCM 令牌，这是必需的，因为 APNs 令牌是发送推送通知的唯一方式。

func sendPushNotification(to token: String, title: String, body: String, userInfo: [String: Any]) {
let payload: [String: Any] = ["title": title, "body": body, "sound": "sound.caf"]
let paramString: [String: Any] = ["to": token, "notification": payload, "data": userInfo]

let urlString = "https://fcm.googleapis.com/fcm/send"
let url = NSURL(string: urlString)!
let request = NSMutableURLRequest(url: url as URL)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject:paramString, options: [.prettyPrinted])
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("key=(Keys.gmsServerKey)", forHTTPHeaderField: "Authorization")
let task =  URLSession.shared.dataTask(with: request as URLRequest)  { (data, response, error) in
do {
if let data = data {
if let object  = try JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.allowFragments) as? [String: Any] {
NSLog("Received data: (object))")
}
}
} catch let err as NSError {
print(err.debugDescription)
}
}
task.resume()
}
