我对开发很陌生,在这个主题上找不到很多端到端的支持.我使用firebase帮助页面做了我能做的事情.
我无法在我的ios设备上收到通知,但FCM在android上完美运行.
这是我从xcode的appdelegate

import UIKit
import Firebase
import FirebaseMessaging
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {

    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        UIApplication.shared.applicationIconBadgeNumber = 0
        // Override point for customization after application launch.
        if #available(iOS 10.0, *) {
            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.current().delegate = self

            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: {_, _ in })

            // For iOS 10 data message (sent via FCM)
            //FIRMessaging.messaging().remoteMessageDelegate = self

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

        application.registerForRemoteNotifications()

        FirebaseApp.configure()
        return true
    }

    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let token1 = Messaging.messaging().fcmToken
        print("FCM token: \(token1 ?? "")")
        var request = URLRequest(url: URL(string: "http://www.myurl.com/register.php")!)
        request.httpMethod = "POST"
        let postString = "Token="+token1!
        request.httpBody = postString.data(using: .utf8)
        let task = URLSession.shared.dataTask(with: request) { data, response, error in
            guard let data = data, error == nil else {                                                 // check for fundamental networking error
                print("error=\(String(describing: error))")
                return
            }

            if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {           // check for http errors
                print("statusCode should be 200, but is \(httpStatus.statusCode)")
                print("response = \(String(describing: response))")
            }

            let responseString = String(data: data, encoding: .utf8)
            print("responseString = \(String(describing: responseString))")
        }
        task.resume()
    }

    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        print("Registration failed!")
    }

    func applicationWillResignActive(_ application: UIApplication) {
        // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
        // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
    }

    func applicationDidEnterBackground(_ application: UIApplication) {
        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
    }

    func applicationWillEnterForeground(_ application: UIApplication) {
        // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
    }

    func applicationDidBecomeActive(_ application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    }

    func applicationWillTerminate(_ application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    }

    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter,  willPresent notification: UNNotification, withCompletionHandler   completionHandler: @escaping (_ options:   UNNotificationPresentationOptions) -> Void) {

        // custom code to handle push while app is in the foreground
        print("Handle push from foreground\(notification.request.content.userInfo)")

        let dict = notification.request.content.userInfo["aps"] as! NSDictionary
        let d : [String : Any] = dict["alert"] as! [String : Any]
        let body : String = d["body"] as! String
        let title : String = d["title"] as! String
//        print("Title:\("FOSG NOTIFICATION") + body:\(body)")
        self.showAlertAppDelegate(title: "Federation Of Safety Glass",message:body,buttonTitle:"ok",window:self.window!)

    }

    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        // if you set a member variable in didReceiveRemoteNotification, you  will know if this is from closed or background
        print("Handle push from background or closed\(response.notification.request.content.userInfo)")
    }

    func showAlertAppDelegate(title: String,message : String,buttonTitle: String,window: UIWindow){
        let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.alert)
        alert.addAction(UIAlertAction(title: buttonTitle, style: UIAlertActionStyle.default, handler: nil))
        window.rootViewController?.present(alert, animated: false, completion: nil)
    }
    // Firebase ended here

}

这是我在php上的服务器端的代码

  $tokens = array(); $mess = '';
    // queries from db to set the values of variables.
    function send_notification ($tokens, $message)
    {
        $url = 'https://fcm.googleapis.com/fcm/send';
        $fields = array(
             'registration_ids' => $tokens,
             'data' => $message
            );
        $headers = array(
            'Authorization:key = **key ',
            'Content-Type: application/json'
            );
       $ch = curl_init();
       curl_setopt($ch, CURLOPT_URL, $url);
       curl_setopt($ch, CURLOPT_POST, true);
       curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
       curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
       curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);  
       curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
       curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
       $result = curl_exec($ch);           
       if ($result === FALSE) {
           die('Curl failed: ' . curl_error($ch));
       }
       curl_close($ch);
       return $result;
    }
    $message = array(
        "body" => $mess,
        "message" => $mess,
        "title" => "FOSG NOTIFICATION",
        "sound" => 1,
        "vibrate" => 1,
        "badge" => 1,
    );
    $t = implode('',$tokens);
    if(t != '') $message_status = send_notification($tokens, $message);

请帮我学习并解决我的问题

解决方法:

刚刚发送json之前更改了字段名称

改变以下内容：

$fields = array(
             'registration_ids' => $tokens,
             'data' => $message
            );

至

$fields = array(
             'registration_ids' => $tokens,
             'notification' => $message,
             'priority' => 'high'
            );
