我尝试将Firebase中onAuth()
请求的回调绑定到RxJS可观察对象。
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:
无法阅读财产' O'在BoundCallbackObservable.X.Ig [as callbackFunc]
中未定义
提前感谢您的帮助!

似乎问题是执行了错误的上下文回调函数。这应该解决它:
let auth = Observable.bindCallback(ref.onAuth.bind(ref));
