不推荐使用Firebase InstanceID.instanceID().token()方法 [英] Firebase InstanceID.instanceID().token() method is deprecated

问题描述

我正在使用swift和firebase.以前，我使用以下方法获取firebase令牌，然后将其用于存储到数据库中以发送通知.

I am working with swift and firebase. Previously I was using following method to get firebase token which then I was using to store into database to send notifications.

InstanceID.instanceID().token()

现在，由于我已经更新了Firebase，因此该方法已被弃用.

Now this method is showing as deprecated since i have updated my firebase.

'token()' is deprecated: Use instanceIDWithHandler: instead.

我不知道如何使用我尝试过的instanceIDWithHandler，但不知道如何获得令牌.

I don't know how to use instanceIDWithHandler i have tried following but don't know how to get token.

func instanceID(handler: @escaping InstanceIDResultHandler){

    }

请帮助. 预先谢谢你.

Please help. Thank you in advance.

推荐答案

获取当前注册令牌

注册令牌是通过方法messaging:didReceiveRegistrationToken:传递的.通常每个应用程序以FCM令牌开始一次调用此方法.调用此方法时，是进行以下操作的理想时间:

Registration tokens are delivered via the method messaging:didReceiveRegistrationToken:. This method is called generally once per app start with an FCM token. When this method is called, it is the ideal time to:

• 如果注册令牌是新的，请将其发送到您的应用程序服务器.
• 为主题注册注册令牌.仅对于新订阅或用户重新安装应用程序的情况，才需要这样做.

您可以直接使用 instanceIDWithHandler: 检索令牌.该回调提供了一个 InstanceIDResult ，其中包含令牌.如果InstanceID检索以任何方式失败，将提供一个非null的错误.

You can retrieve the token directly using instanceIDWithHandler:. This callback provides an InstanceIDResult, which contains the token. A non null error is provided if the InstanceID retrieval failed in any way.

您应该导入FirebaseInstanceID

You should import FirebaseInstanceID

  import FirebaseInstanceID

目标C

在您的getTokenMethod上

on your getTokenMethod

[[FIRInstanceID instanceID] instanceIDWithHandler:^(FIRInstanceIDResult * _Nullable result,
                                                NSError * _Nullable error) {
if (error != nil) {
NSLog(@"Error fetching remote instance ID: %@", error);
} else {
NSLog(@"Remote instance ID token: %@", result.token);
}
}];

快速

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