firebase-authentication

问题 I am working on a sign-in page using AngularJS and Firebase. So far, most of my code has been working fine, until I tried to add notifications. It seems that the won't display when ng-show says that they should. It takes two clicks to work, which should never be the case. As of now, I have the following button. <button ng-click="cna()" type="button" class="btn btn-success ban block" style="width:50%">Create New Account</button> The cna() function is the Create New Account function. This looks

问题 I want to do an action for user that login for the first time (signed up) using google account and another action if the user has already login before. if some user has been and still logged in using their Google account, we can use this lines of code Auth.auth().addStateDidChangeListener { (auth, user) in if user == nil { self.goToLoginVC() } } but how can I differentiate if a user login for the first time (signed up) or not ? is there any particular method to accomplish this?

问题 I am using Firebase as backend for my Internet of Things app. Using python on my Raspberry Pi, I am storing data on Firebase. As of currently my database is public for r/w. I have created an dummy account using Console>Auth>Users. I want to use this account to sign in to my Firebase App through my Raspberry Pi using Python with REST or any lib.

问题 I would like to handle different errors that could happening in Dart. I am using try/catch but wondering how to determine between the different errors that can occur.

Whilst having this error when the username/password is incorrect: PlatformException(Error 17009, FIRAuthErrorDomain, The

问题 So I setup email/password register and login. That is working. I thought Firebase took care of this but apparently not. I want, after the user closes the app, to be logged in already next time they open the app. What is missing? class LoginActivity : AppCompatActivity(){ lateinit var auth: FirebaseAuth lateinit var user: FirebaseAuth override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_login) auth = FirebaseAuth.getInstance()

问题 I am writing to the database and trying to read it, it always says: failed: permission_denied when using the user rules from Firebase. I am trying to write and read from Firebase to write the first and last name. The tree layout is below. The user logs in on the first storyboard and the read and write are on different storyboards and view controllers. Do I need to authenticate on the same VC as where I am trying to get the information? I am able to generate the UserID on different VC's so I

问题 Everytime at the 3th relaunch, my app gets stuck on a dark screen. I have no clue why, I have checked out the Facebook and Firebase docs, followed examples (github).

问题 I'm coding an app which makes use of Firebase Authentication to authenticate with my backend server. I'm offering Google Sign-In and Email/Password based authentication. Email/Password is trivial. This is my flow for using Google Sign-In: 1) I create a mGoogleApiClient = new GoogleApiClient with .addApi(Auth.GOOGLE_SIGN_IN_API, gso) , where gso = GoogleSignInOptions with .requestIdToken(...)) and .requestEmail() 2) I call startActivityForResult( signInIntent , RC_GOOGLE_SIGN_IN); where
