关于javascript：如何获取Firebase实时数据库AuthToken


How to get the Firebase Realtime Database AuthToken

我从开发人员那里获得了基于Firabase Realtime DB的Ionic App的代码。 尝试启动应用程序时，我会收到此错误消息。

[ng] src / app / data-service.service.ts(14,36)中的错误：错误TS2339：类型'{apiKey：string;类型不存在属性'authToken' authDomain：字符串; databaseURL：字符串; projectId：字符串； storageBucket：字符串； messagesSenderId：字符串； }'。

不幸的是，我无法弄清楚如何从Firebase获取authToken。

提前致谢！

我发现这种方法：

firebase.auth().currentUser.getIdToken(/* forceRefresh */
true).then(function(idToken) {
  // Send token to your backend via HTTPS

}).catch(function(error) {
  // Handle error
});
