我试图收到从firebase云信使发送到单个设备的通知。我已经安装了firebase,当我运行程序时,控制台打印出我尝试用来向该设备发送消息的fcm令牌(我使用的是真正的iPhone)。消息发送正常但我的iPhone上没有任何内容。我在App Delegate中实现了以下代码:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UIApplication.shared.setMinimumBackgroundFetchInterval(UIApplicationBackgroundFetchIntervalMinimum)
if #available(iOS 10.0, *)
{
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .sound, .alert]) { (granted, error) in
if granted
{
//self.registerCategory()
}
}
// For iOS 10 data message (sent via FCM)
Messaging.messaging().delegate = self
}
else
{
let settings: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert,.badge,.sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
//Configuring Firebase
FirebaseApp.configure()
// Add observer for InstanceID token refresh callback.
NotificationCenter.default.addObserver(self, selector: #selector(self.tokenRefreshNotification), name: NSNotification.Name.InstanceIDTokenRefresh, object: nil)
return true
}
//Receive Remote Notification on Background
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void)
{
Messaging.messaging().appDidReceiveMessage(userInfo)
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{
Messaging.messaging().apnsToken = deviceToken
}
@objc func tokenRefreshNotification(notification: NSNotification)
{
if let refreshedToken = InstanceID.instanceID().token()
{
print("InstanceID token: \(refreshedToken)")
}
// Connect to FCM since connection may have failed when attempted before having a token.
connectToFcm()
}
func connectToFcm()
{
Messaging.messaging().shouldEstablishDirectChannel = true
}
func applicationDidBecomeActive(application: UIApplication)
{
connectToFcm()
}
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Firebase registration token: \(fcmToken)")
// TODO: If necessary send token to application server.
// Note: This callback is fired at each app startup and whenever a new token is generated.
}
This is the response I get from the Firebase end
所以它说没有发送消息,我很困惑,因为它是我的设备刚刚输出的令牌。
如何了解或解决此问题?

从fcm控制台运行messege之前检查.p12文件已上传
然后实现消息处理方法 在前景和背景
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
Messaging.messaging().appDidReceiveMessage(userInfo)
if let messageID = userInfo[gcmMessageIDKey] {
}
print(userInfo)
completionHandler([.alert, .badge, .sound])
}
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: @escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
completionHandler()
}
extension AppDelegate : MessagingDelegate {
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
print("Firebase registration token: (fcmToken)")
}
Messaging.messaging().shouldEstablishDirectChannel to true.
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
print("Received data message: (remoteMessage.appData)")
}
}
