问题 I'm working with Firebase for the first time on a practice project and I'm having a very difficult time setting up the ability for users to log in to their accounts. I've successfully set up registration but so far I can't get log in and check auth state to work properly. The error I keep receiving in the console is "Uncaught ReferenceError: Firebase is not defined" I've done some research on my own but the only answers I seem to find are ones saying you need to include the script tags for

问题 My app has gmail and facebook authentication integrated through Firebase. I noticed if someone signs up with their gmail then signs up with Facebook, if the Facebook had the same email as their gmail then they'll get the error: "The email address is already in use by another account." Is the only reasonable way to handle this to tell the user to sign in with different credentials? Maybe show a message like "Email already in use, please sign up with different account"? 回答1: There are 3 ways in

问题 I want to detect if a user has signed in using Facebook or email, etc... I found an answer for Android, but I am programming in Swift for iOS and I am not sure how to translate the code entirely. The android/java code is : for (UserInfo user:FirebaseAuth.getInstance().getCurrentUser().getProviderData()) { if (user.getProviderId().equals("facebook.com")) { System.out.println("User is signed in with Facebook"); } } I have tried to translate it, but I can't seem to figure out how to access the

问题 I'm introducing Google Sign-In to my app and whilst both Google and Firebase documentation is thorough enough, what I have done as they suggested is not sufficient... I am still getting this error. Hopefully this will help others with finding a solution to the problem when implementing their SDK....thanks in advance for reviewing this chunky one: Here's the Firebase guide and the Google guide: So Added Google to podfile - CHECK Added line into Bridging-Header - CHECK Added GoogleService-Info

问题 I'm using in my app Google sign-in method and I have updated today my dependencies to: implementation "com.google.firebase:firebase-core:17.1.0" implementation "com.google.firebase:firebase-auth:19.0.0" And I stared to get warnings about deprecated classes.

How to fix it ? 回答1: For Android and iOS, the App store and Play store name are used as those are already vetted before release. If this is a web app, the page's domain name is used as the app name. The reason is because this is the only verifiable identifier associated with the web app. The same thing is used for OAuth redirects. When

问题 Two apps are in the same Firebase project. One app deleted a user from Firebase Auth. But another app still get user uid from somewhere, maybe cache, and access the data in Firebase database with Auth's uid too. I mean I can still get "user.uid" by let user = FIRAuth.auth().currentUser , if keeping sign-in. The apps both set FIRDatabase.database().persistenceEnabled = true . I would like to sing out or refresh cache at all apps if the user was deleted from Auth accordingly. 回答1: You can

Do NOT use this value to // authenticate with your
