将 Firebase onAuth 回调绑定到可观察对象

Question

我正在尝试将回调结果绑定到 Firebase 中的 onAuth() 请求到 RxJS observable。

let auth = Observable.bindCallback(ref.onAuth);
let source = auth();
let subscription = source.subscribe(
    (x) => console.log(x),
    (e) => console.log(e)
);

我收到错误：

Cannot read property 'O' of undefined at BoundCallbackObservable.X.Ig [as callbackFunc]

在此先感谢您的帮助！

看来问题是执行的上下文回调函数不正确。这应该可以解决：

let auth = Observable.bindCallback(ref.onAuth.bind(ref));
