问题 So if I have an E-commerce App that doesn't require Login/Auth, and my users buy in the store, then after verifying the transaction the backend writes the order in the database. The thing is that my Realtime Database just relies on Stripe transaction key (i.e, someone has paid for an item) to be able to write on the DB, because my rules are set so anyone can write, otherwise I would need every user to log in, but that's not what I want. Firebase recently notified me that my rules are weak.

问题 So, I am trying to create a sign-in and sign-up flow using firebase with primary requirement using phone number. But I found that I am only able to sing up the user using createUserWithEmailAndPassword only. Now the issue is how do I sign up the user using phone number. If not then how does firebase sign in user using phone number? 回答1: A Firebase Authentication user account is created when signing up/in with phone number when you call the signInWithCredential method. At that point you can

问题 Once the user signs in with Google, I want to take them to the home screen; however, the code does not fully execute this. This is the code: func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) { if let error = error { if (error as NSError).code == GIDSignInErrorCode.hasNoAuthInKeychain.rawValue { print("The user has not signed in before or they have since signed out.") } else { print("\(error.localizedDescription)") } return } let firstName = user

问题 I am trying to test my security rules using the Firestore emulator. I made a firestore.rules security rule that disallows all reads and writes: service cloud.firestore { match /databases/{database}/documents { allow read, write: if false; } } I started the Firestore emulator from the terminal: firebase emulators:start --only firestore I then initialized my Firestore client: import firebase_admin from firebase_admin import firestore firebase_app = firebase_admin.initialize_app() self.client =

问题 very new to ios development and Firebase. I have implemented a standard run-of-the-mill ui flow where the app opens to a splash-screen, where it's checked whether user is signed in or not and depending on the state the user is redirected to the login screen or home screen. I'm trying to get a user id from auth listener, and some of my getUserId calls from the userManager are happening before the firebase auth gives a non-nil user id, and the user always ends up going to the registration

问题 I'm trying to check if a user is logged in or not on my React webpage using Firebase, however I keep getting an error TypeError: Cannot read property 'onAuthStateChanged' of undefined , the line of code it links to is as followed: Login.js: authListener() { Fire.auth.onAuthStateChanged((user) => { if (user) { this.setState({ user }) } else { this.setState({ user: null }) } })} Fire.js: import firebase from 'firebase' const config = { apiKey: "xxx", authDomain: "xxx", databaseURL: "xxx",

问题 How one can forbid new users to sign in using Firebase Email Link? So only exiting customers can sign in. I want to register only users that will subscribe via Stripe and create new account server-side. Also, if I may do it in the same thread: how can I edit email template that is sent to the new user? In console this one is not available. 来源： https://stackoverflow.com/questions/61779992/firebase-email-link-only-for-existing-users-forbid-new-users
