firebase-authentication

问题 I followed the Firebase docs for web development and I used the user.updateProfile method to add a display name to the user's profile. After signing in, I used console.log(user) and it worked but when I call updateProfile() , the value of user is null. Any solutions? Here is the relevant code: var button = document.getElementById("profile-button"); var username = document.getElementById("username-Box").value; var user = firebase.auth().currentUser; auth.onAuthStateChanged(user =>{ console.log

问题 In my system I need to create users from an authenticated user, but for this I need to create a user through the createUserWithEmailAndPassword method and when I create the user through this method the authentication status changes to the user that was created at the moment. Is there a way to create users from an authenticated user without making signIn for the user created after it was created by the createUserWithEmailAndPassword method? I have a system developed in Angular + Node.js

问题 When I log into a firebase app using signInWithEmailAndPassword(email, password) , the user is logged in. Then, if I reload the page, the user is no longer logged in. If I go to another webpage with the same firebase apiKey and everything, the user still isn't logged in. How would I go about making sure the user stays logged in until firebase.auth().signOut() is called? 回答1: Simply using firebase.auth().currentUser usually won't work because when that's loaded, Firebase usually hasn't

问题 I am building a server route that I wish to restrict for use only by authenticated users. I plan to send a user.uid with a POST to this route, and I want to validate the UID is one that exists in Firebase. I know I can add UIDs manually in Firebase and check against this data, but is it possible to see what UIDs Firebase authentication is tracking? I think this approach would be better then checking against my own list. The purpose for this is to ensure that these routes are not accessed with

问题 I need to create and use a database entry with all details (uid, name etc) for each user that logs in to the application I am having trouble storing user data in order to use and retrieve user profile info using Firebase in Android. I found this documentation on the old version of Firebase but this does not seem to work any longer. Does anyone know how to reproduce the above code so it works with the new version of Firebase? Many thanks in advance. Edit - code below: final Firebase ref = new

问题 Within the Firebase console I have specifically set it to only allow "One account per email address". This is found on the sign-in method tab under "advanced". I have an account created using the Google login method that has an address like "me@gmail.com". If I then choose to sign-in via Facebook using an account that also uses "me@gmail.com", Firebase is allowing it with the exception that the email address in the Users entity is null. The Firebase documentation states: if you don't allow
