You can use the code below and hope it works out for you:
export interface AuthResponseData {
kind: string;
idToken: string;
email: string;
refreshToken: string;
localId: string;
expiresIn: string;
registered?: boolean;
}
export class AuthService implements OnDestroy {
private _user = new BehaviorSubject<User>(null);
get token() {
return this._user.asObservable().pipe(
map(user => {
if (user) {
return user.token;
} else {
return false;
}
})
);
}
constructor(private http: HttpClient) { }
signup(email: string, password: string) {
return this.http
.post<AuthResponseData>(
`https://identitytoolkit.googleapis.com/v1/accounts:signUp?key=${yourAPIKey}`,
{ email, password, returnSecureToken: true })
.pipe(tap(this.setUserData.bind(this)));
}
login(email: string, password: string) {
return this.http
.post<AuthResponseData>(
`https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=${yourAPIKey}`,
{ email, password, returnSecureToken: true })
.pipe(tap(this.setUserData.bind(this)));
}
private setUserData(userData: AuthResponseData) {
const expirationTime = new Date(new Date().getTime() + +userData.expiresIn * 1000);
const user = new User(userData.localId, userData.email, userData.idToken, expirationTime);
this._user.next(user);
this.storeAuthData(userData.localId, userData.idToken, expirationTime.toISOString(), userData.email);
}
private storeAuthData(userId: string, token: string, tokenExpirationDate: string, email: string) {
const data = JSON.stringify({ userId, token, tokenExpirationDate, email });
Plugins.Storage.set({ key: 'authData', value: data });
}
}
