Change/update 通过代码强制使用 Firebase 通知令牌或实例 ID？

Question

我应该如何更改或请求 firebase 中的令牌？ firebase 根据设备信息生成的唯一令牌。

Answer 1

在为推送通知生成新的或更改的 firebase 令牌时遇到许多麻烦后，现在我得到了答案。

1) 删除旧的 Firebase 令牌

let instance = FIRInstanceID.instanceID()
_ = FIRInstanceID.delete(instance)
FIRInstanceID.instanceID().delete { (err:Error?) in
    if err != nil{
        print(err.debugDescription);
    } else {
        print("Token Deleted");
    }
}

2) 请求新的 Firebase 令牌

if let token = FIRInstanceID.instanceID().token() {
    print("Token \(token) fetched");
} else {
    print("Unable to fetch token");
}

FIRMessaging.messaging().connect { (error) in
    if (error != nil) {
        print("Error connecting to FCM. \(error.debugDescription)")
    } else {
        print("Connected to FCM.")
    }
}

更新 SWIFT 4 和 Firebase 4.8.2（执行简单的两个步骤）

1) 删除旧令牌

let instance = InstanceID.instanceID()
instance.deleteID { (error) in
    print(error.debugDescription)
}

2) 请求新令牌

if let token = InstanceID.instanceID().token() {
    print("Token : \(token)");
} else {
    print(“Error: unable to fetch token");
}

Messaging.messaging().shouldEstablishDirectChannel = true

您可以在 MessagingDelegate 方法 didReceiveRegistrationToken 和刷新令牌中获取更新的令牌。

func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
    print("Firebase Token :  \(fcmToken)")
}

Answer 2

我了解到您想更改或更新 firebase 令牌。

创建以下两个方法

func registerFirebaseToken() {
    if let token = InstanceID.instanceID().token() {
        print("FIREBASE: Token \(token) fetched")
    } else {
        print("FIREBASE: Unable to fetch token");
    }

    Messaging.messaging().shouldEstablishDirectChannel = true
}

func unregisterFirebaseToken(completion: @escaping (Bool)->()) {
    // Delete the Firebase instance ID
    InstanceID.instanceID().deleteID { (error) in
        if error != nil{
            print("FIREBASE: ", error.debugDescription);
            completion(false)
        } else {
            print("FIREBASE: Token Deleted");
            completion(true)
        }
    }
}

调用

unregisterFirebaseToken(:)

并在闭包中检查是否为真然后调用

registerFirebaseToken()

这将是第一次失败，并且将调用其中一个委托方法，即

extension AppDelegate: MessagingDelegate {
    func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
        registerFirebaseToken()
    }
}

这次

registerFirebaseToken()

将从委托方法中再次调用，您将获得一个新令牌。

Answer 3

Updated Answer for Swift 4, FireBase 4.8.2, FirebaseMessaging (2.0.8)

debugPrint("Existing Token :- \(Messaging.messaging().fcmToken!)")

let instance = InstanceID.instanceID()
instance.deleteID { (error) in
    print(error.debugDescription)
}

if let token = InstanceID.instanceID().token() {
    print("Token \(token) fetched");
} else {
    print("Unable to fetch token");
}
Messaging.messaging().shouldEstablishDirectChannel = true

We receive this updated token in MessagingDelegate method as well as in Refresh Token

func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
    print("Firebase registration token: \(fcmToken)")
}

Answer 4

目前 InstanceID.instanceID().token() 已弃用。

你应该使用这个：

let instance = InstanceID.instanceID()
instance.deleteID { (error) in
  print(error.debugDescription)
}

instance.instanceID { (result, error) in
  if let error = error {
    print("Error fetching remote instange ID: \(error)")
  } else {
    print("Remote instance ID token: \(String(describing: result?.token))")
  }
}
Messaging.messaging().shouldEstablishDirectChannel = true

然后在 AppDelegate 中：

extension AppDelegate: MessagingDelegate {

func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
    //Here is your new FCM token
    print("Registered with FCM with token:", fcmToken)
}

已针对 Firebase 消息传递 7.3.0 更新

class func regenerateFCM(){
    Installations.installations().delete { (err) in
        if let err = err {
            print(err)
        }else{
            Installations.installations().authTokenForcingRefresh(true) { (result,err) in
                if let result = result {
                    print(result)
                   
                    Messaging.messaging().deleteToken { (err) in
                        if let err = err {
                            print(err)
                        }else{
                            print("FCM TOKEN DELETED")
                            Messaging.messaging().token { (token, err) in
                                if let token = token {
                                    print("NEW FCM TOKEN GENERATED")
                                    print(token)
                                }
                                if let err = err {
                                    print("ERROR WHILE GENERATING NEW FCM TOKEN")
                                    print(err)
                                }
                            }
                        }
                    }
                    
                }else if let err = err {
                    print(err)
                }
            }
        }
    }
}

Firebase 8.5.0 更新

Messaging.messaging().deleteToken { err in
        if let err = err {
            print("Error while generating new FCM Token")
            print(err)
        }else{
            Messaging.messaging().token { token, err in
                 if let token = token {
                    print("NEW FCM TOKEN GENERATED")
                    print(token)
                }
            }
        }
    }
