Question

我在我的应用中添加了google firebase - 创建谷歌帐户，创建谷歌应用程序，上传APNS认证（.pem和在另一项服务中工作），并从控制台发送推送通知，我的应用程序没有收到它。在Firebase控制台中，我看到状态已完成，但设备的近似数量为＆＃34; - ＆＃34;

当然，我更新了条款配置文件和APNS证书

service docker stop

rm -r /var/lib/docker/*

service docker start

Answer 1

我看到的第一件事是没有连接到FIRMessaging的电话。尝试将其添加到AppDelegate：

func applicationDidBecomeActive(application: UIApplication) {
    FIRMessaging.messaging().connectWithCompletion { error in
        print(error)
    }
}

使用以下代码。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
    if #available(iOS 10.0, *)
    {
        // For iOS 10 display notification (sent via APNS)
        UNUserNotificationCenter.currentNotificationCenter().delegate = self
        UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert])          { (granted, error) in
                if granted
                {
                //self.registerCategory()
             }
         }
         // For iOS 10 data message (sent via FCM)
         FIRMessaging.messaging().remoteMessageDelegate = self
    }
    else
    {
        let settings: UIUserNotificationSettings =  UIUserNotificationSettings(forTypes: [.Alert,.Badge,.Sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }          
    application.registerForRemoteNotifications()        
    //Configuring Firebase
    FIRApp.configure()
    // Add observer for InstanceID token refresh callback.
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotification), name: kFIRInstanceIDTokenRefreshNotification, object: nil)     
     return true
}

//Receive Remote Notification on Background
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void)
{
    FIRMessaging.messaging().appDidReceiveMessage(userInfo)
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData)
{
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Sandbox)
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Prod)
}

func tokenRefreshNotification(notification: NSNotification)
{
    if let refreshedToken = FIRInstanceID.instanceID().token()
    {
            print("InstanceID token: \(refreshedToken)")
    }
    // Connect to FCM since connection may have failed when attempted before having a token.
    connectToFcm()
}

func connectToFcm()
{
    FIRMessaging.messaging().connectWithCompletion { (error) in
            if (error != nil)
            {
                print("Unable to connect with FCM. \(error)")
            }
            else
            {
                print("Connected to FCM.")
            }
    }
}

func applicationDidBecomeActive(application: UIApplication)
{            
    connectToFcm()
}

您可能在PUSH JSON中使用了Data或aps键，该键用于向设备发送通知。它应该可以正常工作，但在极少数情况下，它即使在fcm / send api会给您带来成功的情况下也无法正常工作，但通知不会到达特定的设备。此问题通常发生在iOS设备中。

对我有用的解决方案是添加通知键而不是数据。

          <div class="field">
            <label class="label">Category</label>
           <%= f.collection_select :category_id, Category.all, :id, :name %>  
          </div>

            <div class="field">
                   <label class="label">Sub Category</label>
                   <%= f.select :subcategory_id, options_for_select([])  %>  
             </div>



               <script>

                 $(document).ready(function(){
                 var getSubcategories = function(category_id){
                 var subcategories = $('#service_subcategory_id');
                 $($subcategories).empty();

                $.service('/subcategories/find_by_category', { category_id: category_id},  
                function(data){
                $.each(data.subcategories, function(index, subcategory){
                var option = $('<option />');
                option.attr('value', subcategory.id);
                option.text(subcategory.name);
                option.appendTo($subcategories);

                 });

                   })

                    };

              var getSelectedCategory = function(){
                return $('#service_category_id').val();

              };

               $('#service_category_id').change(function() {
             var category_id = getSelectedCategory();
           getSubcategories (category_id);

            });

           getSubcategories(getSelectedCategory());


             });

          </script>

如果您是从后端发送的，或者您无权访问Firebase控制台。然后，您也可以通过POSTMAN测试并发送通知。但是您必须具有SERVER KEY，它可以从Firebase控制台的Cloud Messaging设置中获取。

readyException.js:6 Uncaught ReferenceError: $subcategories is not defined
at getSubcategories (edit:493)
at HTMLDocument.<anonymous> (edit:520)
at mightThrow (deferred.js:97)
at process (deferred.js:139)

如果您需要了解我们可以在FIREBASE通知中发送的内容，则另外提供详细且完整的有效载荷：

{ 
    "to" : "device token",
    "notification":{
            "body": "test",
            "title": "test"
                }
}

firebase iOS没有收到推送通知
