firebase-authentication

问题 I have a set of Firebase Functions that works as an API for an application. These Firebase Functions connect to the database with admin privileges as this: const serviceAccount = require(`./config/xxx-firebase-adminsdk.json`); admin.initializeApp({ credential: admin.credential.cert(serviceAccount), databaseURL: DATABASE_URL, }); I was able to create a custom token and I'm receiving/decoding it in the server but I cannot make use of the security rules because the Firebase function is

问题 I am trying to add document to my cloud firestore DB. In this manner. Future<String> currentlyIn()async{ FirebaseAuth auth = FirebaseAuth.instance; String fuser = await auth.currentUser(); }); return fuser.uid; } Map<String, dynamic> votedown() { Map<String, dynamic> comdata = <String, dynamic>{ 'user_Id':currentlyIn(), 'actual_vote':0, 'voteUp': false, }; return comdata; } DocumentReference storeReference =Firestore.instance.collection('htOne').document('docq'); await storeReference.setData

问题 according to the guide, the firebase auth state persistance is set before the actual login method is called: firebase.auth().setPersistence(firebase.auth.Auth.Persistence.SESSION) .then(function() { // Existing and future Auth states are now persisted in the current // session only. Closing the window would clear any existing state even // if a user forgets to sign out. // ... // New sign-in will be persisted with session persistence. return firebase.auth().signInWithEmailAndPassword(email,

问题 I finally got my authentication to work in terms of creating users and logging in and out. But now, I want to implement something that checks if the user already exists in Firebase. I've looked it up but can't seem to find a concrete answer. For example, if my email address is: abc12@gmail.com and someone else tries to signup with the same email address, how do I tell them it's already taken? login(e) { e.preventDefault(); fire.auth().signInWithEmailAndPassword(this.state.email, this.state

问题 In the past, I have used firebase.auth in the web client and once a user creates another user, I link certain security logic: Once the user has been created I send an email to verify your email with the function user.sendEmailVerification (). As the user was created by another user, I assign a default password and use the sendPasswordResetEmail () function so that the user registers his new password. That has worked well for me so far, but now for many reasons I need to move that logic to my

问题 I have a multi-module multi-flavor android project, the modules are as follows: core module, which is an android library that holds common stuff, including library dependencies. authentication module, which is as the name suggests, a module that contains a bunch of UI activities and is responsible for authenticating users.
