在FCM中使用UNNotificationServiceExtension不会被调用

如何解决在FCM中使用UNNotificationServiceExtension不会被调用

我不知道可能是什么问题，但是FCM的任何推送都不会调用我的unnotificationserviceextension。我从python3脚本调用了FCM，到目前为止，它仍然有效（我收到了推送通知，但始终带有默认文本，而不是修改后的文本）。

firebaseHeaders = {
    "Content-Type":"application/json","Authorization":"key=MY_KEY"
}

firebaseBody = {
    "to":device_token,"priority":"high","mutable-content":True,"apns-priority":5,"notification": { "title_loc_key":"push.goalReachedTitle","body_loc_key":"push.goalReachedContentRemote","body_loc_args":[str(entry['value']),entry['region']],"sound":"default","badge":1 },"data": { "values":data,"region":entry['region'],"value":entry['value'] }
}

firebaseResult = requests.post("https://fcm.googleapis.com/fcm/send",data=None,json=firebaseBody,headers=firebaseHeaders)

我的扩展程序也很基本（用于测试），我已经尝试将其删除并再次将其添加到我的主应用程序项目中。

class NotificationService: unnotificationserviceextension {

    var contentHandler: ((UNNotificationContent) -> Void)?
    var bestAttemptContent: UNMutableNotificationContent?

    override func didReceive(_ request: UNNotificationRequest,withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
        self.contentHandler = contentHandler
        bestAttemptContent = (request.content.mutablecopy() as? UNMutableNotificationContent)
        
        if let bestAttemptContent = bestAttemptContent {
            bestAttemptContent.title = bestAttemptContent.title + " [TEST 123]"            
            contentHandler(bestAttemptContent)
        }
    }
    
    override func serviceExtensionTimeWillExpire() {
        // Called just before the extension will be terminated by the system.
        // Use this as an opportunity to deliver your "best attempt" at modified content,otherwise the original push payload will be used.
        if let contentHandler = contentHandler,let bestAttemptContent =  bestAttemptContent {
            contentHandler(bestAttemptContent)
        }
    }
}

任何人都知道我仍然可以检查，测试或错过什么吗？
