firebase-authentication

问题 I added Firebase auth to my Reactjs (and Redux) web app and everything works perfectly. I'm using email / password sign in, and call firebase.auth().signInWithEmailAndPassword which persists on reloads, tab changes, etc. However, after about an hour, the auth session appears to expire and currentUser is set to null. It feels like there should be a setting somewhere in the Firebase console, but after searching through it, I can't find anything. Any help would be really appreciated! 来源： https:/

问题 I created a Firebase project based on Polymer Starter Kit and made some modifications to fix routing, but the sign-in popup immediately closes and logs an error: The popup has been closed by the user before finalizing the operation. The _authenticate function (in the code below) is called to authenticate the user. I was able to properly set it up both on Facebook and Google console, so I'm not sure what the error means. Here's my code: <dom-module id="my-app"> <template> !-- Firebase Setup --

问题 I have a Firebase WebApp which provides info to a user. In addition to the app I need to send push notifications via Firebase Cloud Messaging to users with an Android App. Goal: The user should have one login to the app which both registers them for notifications and loads the WebApp through a WebView. Problem: I can't find an approach which achieves this with a single login. In every case I need to login once for the native app and then once again through the webView. First, some references

问题 I wan't to allow only logged in users to access a certain site. What's the proper way of checking if a user is logged in on load? The code below is my first try, don't really know if it works though. Of course I already wrote db rules, now I want to complete the behavior visually for the user. this.af.auth.subscribe(auth => { if (auth) { //route to other view } else { //do whatever } }); 回答1: You should consider use angular 2 guards, like canActivate. They can help you to do validation before
