Question

非常感谢任何帮助...我想要做的就是使用我的PHP代码向订阅主题＆＃34; global＆＃34;的所有用户发送通知。有谁知道为什么它可能不起作用？由于我希望每个人都使用该应用程序来获取通知，我将订阅所有人（除非有更好的方法）。这是我的PHP尝试将通知发送到我的主题全球：

<?php
    define( 'API_ACCESS_KEY', 'hidden...hidden' );

    $msg = array
    (
        'message'   => 'here is a message. message',
        'title'     => 'This is a title. title',
        'vibrate'   => 1,
        'sound'     => 1
    );

    $fields = array
    (
        'to'            => "/topics/global",
        'data'          => $msg,
        'priority'      => 'high'
    );

    $headers = array
    (
        'Authorization: key=' . API_ACCESS_KEY,
        'Content-Type: application/json'
    );

    $ch = curl_init();
    curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send' );
    curl_setopt( $ch,CURLOPT_POST, true );
    curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
    curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
    curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
    curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );

    $result = curl_exec( $ch );
    curl_close( $ch );
    echo $result;
?>

我缺乏知识但是从$结果回显它看起来不像任何失败信息。这就是我得到的：

{"message_id":7591682951632927615}

在我的Firebase控制台中，我甚至看不到主题＆＃34; global＆＃34;所以我无法测试发送到我的设备上的主题。根据我在线阅读的内容，订阅主题可能需要一段时间才能显示在控制台中。 只是澄清一下，使用设置为应用程序的用户段向所有设备发送通知即可在控制台中使用！

我能做些什么来验证我的应用实际上是在订阅用户主题＆＃34;全球＆＃34;？也许这就是问题所在。这是相关的快速代码：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    FIRApp.configure()

    if #available(iOS 10.0, *) {
        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,
            completionHandler: {_, _ in })

        // For iOS 10 display notification (sent via APNS)
        UNUserNotificationCenter.current().delegate = self
        // For iOS 10 data message (sent via FCM)
        FIRMessaging.messaging().remoteMessageDelegate = self

    } else {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }

    application.registerForRemoteNotifications()

    return true
}


func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
    print("applicationReceivedRemoteMessage")
}


func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    if let refreshedToken = FIRInstanceID.instanceID().token() {
        print("InstanceID token: \(refreshedToken)")
        FIRMessaging.messaging().subscribe(toTopic: "/topics/global")
    }
}


func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.

    /*
     // Print message ID.
     if let messageID = userInfo["gcmMessageIDKey"] {
     print("Message ID: \(messageID)")
     }

     // Print full message.
     print(userInfo)
     */
}


func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.

    if application.applicationState == UIApplicationState.active {

        print("GOT IN HERE")

        var pushNotificationMessage = ""
        if let aps = userInfo["aps"] as? NSDictionary {
            if let alert = aps["alert"] as? NSDictionary {
                if let message = alert["message"] as? NSString {
                    pushNotificationMessage = message as String
                }
            } else if let alert = aps["alert"] as? NSString {
                pushNotificationMessage = alert as String
            }
        }

        let notificationAlert = UIAlertController(title: nil, message: pushNotificationMessage, preferredStyle: .alert)

        let defaultAction = UIAlertAction(title: "OK", style: .default, handler: {
            (alert: UIAlertAction!) -> Void in
        })
        defaultAction.setValue(Constants.activePushNotificationOKColor, forKey: "titleTextColor")

        notificationAlert.addAction(defaultAction)
        self.window?.rootViewController?.present(notificationAlert, animated: true, completion: nil)
    }
}

要发送notification，请将参数存储在notification中，而不是数据：

$fields = array
(
    'to'            => "/topics/global",
    'notification'  => $msg, // <= CHANGED
    'priority'      => 'high'
);

另请参阅Notification payload support文档中的表2a 。 message。

为什么我的Firebase通知发送到某个主题的请求无效（HTTP POST）？
