问题 How can I retrieve a photo of the user with decent resolution that can be used from a mobile app? I looked at the guides and the api docs and the recommended way seemed to be to use FirebaseUser#getPhotoUrl(). This however gives back a url to a photo with resolution 50x50 px, which is too low to be useful. Is there a way for the client to request a higher res photo of the user? I've tested the sdks of Facebook Login and Google Sign-in separately, and in both cases the resolutions of the

问题 I've seen a lot of questions about this, but what confuses me is on the documentation of firebase x nodejs there is a function createUserWithEmailAndPassword() . Everytime I print firebase.auth() it only has these functions : { createCustomToken: [Function], verifyIdToken: [Function], INTERNAL:{ delete: [Function], getToken: [Function], addAuthTokenListener: [Function], removeAuthTokenListener: [Function] } } Also, under the same nodejs documentation, the firebase.auth() says : auth(app)

问题 I'm using AngularFire2 (2.0.0-beta.2) incombination with angular2 (2.0.0-rc.4). I'd like to get access to the native firebase object (not the AngularFire root object) from Angularfire2.

问题 How can I add extra attributes phone number and address to this data set? It seems like Firebase documentation doesn't specify anything about that. I have implemented the login, register and update using firebase.auth() Login : //Email Login firebase.auth().signInWithEmailAndPassword(email, password).then( ok => { console.log("Logged in User",ok.user); }, error => { console.log("email/pass sign in error", error); } ); Register: //Sign Up firebase.auth().createUserWithEmailAndPassword(email,

问题 Thank to Firebase the user can logged with the help of G+, Facebook or Twitter. When they are logged, everything is fine. When the Android app is closed and re-opened, how to reenable the previous succeed logged user with the Firebase API. It is not explained neither in the app demo or in the documentation. For exemple for Facebook, the sdk seems to save the token, that 's why the button is at connected state (showing that you can disconnect). But what about Firebase and for other

问题 I am using firebase to authenticate users in my android app. I provide user an option to reset password in login window. When user click on button, it sends email successfully. However when user clicks on link, it always showing " Try resetting your password again .

问题 Is there a way to check if a user is firebase-authorized before triggering a cloud function? (Or within the function) 回答1: Yes. You will need to send the Firebase ID token along with the request (for example in the Authorization header of an AJAX request), then verify it using the Firebase Admin SDK. There is an in-depth example in the Cloud Functions for Firebase samples repository. It looks something like this (made shorter for SO post): const functions = require('firebase-functions');

问题 I'm trying to check user's phone number on the server side with C++. Client side looks ok, but on the server side I can only decode JWT from client and find out Firebase ID of the user, but of course this is not what I need. I still need to know phone number of the user, and I understand that I can do this with user ID and Firebase admin SDK, but I can't find admin SDK for C++ or any web-API which I could use from everywhere. So, how can I know user's phone number from C++? 回答1: There is no
