Question

我正在使用firebase函数和firestore发送推送通知。更改Firestore数据库时，该功能运行良好，甚至说该消息已成功发送。但是我的设备在后台或前台都没有收到该消息。

我已确保注册令牌正确。用于生产和开发的.p12都包含在项目中。

在didfinishlaunchingwithoptions函数中


Messaging.messaging().delegate = self

InstanceID.instanceID().instanceID { (result, error) in
            if let error = error {
                print("Error fetching remote instance ID: \(error)")
            } else if let result = result {

                let token = result.token

                let db = Firestore.firestore()

                if let driverID = UserDefaults.standard.string(forKey: "driverID"){

                    db.collection("drivers").document(driverID).updateData(["registrationToken":token])

                }

            }

        }

和didreceiveregistrationtoken委托方法

func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {

        print("Firebase registration token: \(fcmToken)")

        let dataDict:[String: String] = ["token": fcmToken]
        NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)

        let db = Firestore.firestore()

        if let driverID = UserDefaults.standard.string(forKey: "driverID"){

            db.collection("drivers").document(driverID).updateData(["registrationToken":fcmToken])

        }

    }

最后将功能部署到Firebase

出于调试目的，我复制粘贴了令牌，而不是从数据库中获取令牌。

exports.sendDispatchedNotification = functions.firestore.document('/dispatching/{cityID}/{dateID}/trips/uncomplete/{tripID}')
    .onUpdate(async (change) => {

      const payload = {
        notification: {
          title: 'Trip Ready',
          body: 'There is a trip ready for you to start.'
        }
      }

      admin.messaging().sendToDevice("TOKEN", payload)
        .then(response => {
          console.log("successfully sent message:", response)
          return
        })
        .catch(error => {
          console.log("Error sending message:", error);
        })

    })

它记录“成功发送的消息：”很好，但是我的设备没有收到消息。

Firebase函数说消息已成功发送，但未收到
