В моем проекте я использую триггер для создания пользовательского документа в Firestore, когда пользователь входит в систему. И это здорово - все отлично работает для входа в Google и входа в Facebook.
Вот этот триггер:
exports.createAccountDocument = functions.auth.user().onCreate(async user => {
const { uid, displayName } = user
const username = displayName;
const email = user.email || user.providerData[0].email;
const profileImageUrl = uid;
const status = "active";
const str = username;
const qwery = [];
for (let i = 0; i < str.length; ++i) {
qwery[i] = str.substring(0, i + 1).replace(/\s/g, "").toLowerCase();
}
const keywords = qwery;
const bio = "";
return await admin
.firestore()
.collection("users")
.doc(uid)
.set({ bio, email, keywords, profileImageUrl, status, uid, username })
})
Например - это метод входа в Facebook:
import SwiftUI
import FBSDKLoginKit
import Firebase
struct FacebookAuthView: UIViewRepresentable {
@Binding var showAnimation: Bool
@Binding var showSheet: Bool
init(showAnimation: Binding<Bool>, showSheet: Binding<Bool>) {
self._showAnimation = showAnimation
self._showSheet = showSheet
}
func makeCoordinator() -> FacebookAuthView.Coordinator {
return FacebookAuthView.Coordinator(showAnimation: self.$showAnimation, showSheet: self.$showSheet)
}
class Coordinator: NSObject, LoginButtonDelegate {
@Binding var showAnimation: Bool
@Binding var showSheet: Bool
init(showAnimation: Binding<Bool>, showSheet: Binding<Bool>) {
self._showAnimation = showAnimation
self._showSheet = showSheet
}
func loginButton(_ loginButton: FBLoginButton, didCompleteWith result: LoginManagerLoginResult?, error: Error?) {
if let error = error {
print(error.localizedDescription)
return
}
guard let token = AccessToken.current else {
return
}
self.showAnimation = true
self.showSheet = false
let credential = FacebookAuthProvider.credential(withAccessToken: token.tokenString)
Auth.auth().signIn(with: credential) { (authResult, error) in
if let error = error, (error as NSError).code == AuthErrorCode.credentialAlreadyInUse.rawValue {
Auth.auth().signIn(with: credential) { result, error in
// continue
print("signIn result: " + authResult!.user.email!)
if let token = firebaseRegistrationPushToken {
checkUserAuthSettings(pushToken: token)
}
}
} else {
// continue
print("Facebook Sign In")
if let token = firebaseRegistrationPushToken {
checkUserAuthSettings(pushToken: token)
}
}
}
}
func loginButtonDidLogOut(_ loginButton: FBLoginButton) {
try! Auth.auth().signOut()
}
}
func makeUIView(context: UIViewRepresentableContext<FacebookAuthView>) -> FBLoginButton {
let view = FBLoginButton()
view.permissions = ["email"]
view.delegate = context.coordinator
return view
}
func updateUIView(_ uiView: FBLoginButton, context: UIViewRepresentableContext<FacebookAuthView>) { }
}
Но когда я пытаюсь создать документ, когда пользователь входит в систему с помощью Swign in с Apple, это не работает. В консоли Firebase в разделе Firebase Authentication я вижу нового пользователя, но в Firestore документ не отображается вообще.
Вот мой метод входа с помощью Apple:
import Foundation
import SwiftUI
import AuthenticationServices
import CryptoKit
import Firebase
struct AppleAuthView: UIViewRepresentable {
@Binding var showAnimation: Bool
@Binding var showSheet: Bool
init(showAnimation: Binding<Bool>, showSheet: Binding<Bool>) {
self._showAnimation = showAnimation
self._showSheet = showSheet
}
func makeCoordinator() -> AppleAuthView.Coordinator {
return AppleAuthView.Coordinator(showAnimation: self.$showAnimation, showSheet: self.$showSheet)
}
class Coordinator: NSObject, ASAuthorizationControllerPresentationContextProviding, ASAuthorizationControllerDelegate {
@Binding var showAnimation: Bool
@Binding var showSheet: Bool
fileprivate var currentNonce: String?
init(showAnimation: Binding<Bool>, showSheet: Binding<Bool>) {
self._showAnimation = showAnimation
self._showSheet = showSheet
super.init()
}
func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor {
let viewController = UIApplication.shared.windows.last?.rootViewController
return (viewController?.view.window!)!
}
func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) {
if let appleIDCredential = authorization.credential as? ASAuthorizationAppleIDCredential {
guard let nonce = currentNonce else {
fatalError("Invalid state: A login callback was received, but no login request was sent.")
}
guard let appleIDToken = appleIDCredential.identityToken else {
print("Unable to fetch identity token")
return
}
guard let idTokenString = String(data: appleIDToken, encoding: .utf8) else {
print("Unable to serialize token string from data: \(appleIDToken.debugDescription)")
return
}
let credential = OAuthProvider.credential(withProviderID: "apple.com", idToken: idTokenString, rawNonce: nonce)
Auth.auth().signIn(with: credential) { (authResult, error) in
if let error = error {
print(error.localizedDescription)
return
}
print("Apple Sign In")
if let token = firebaseRegistrationPushToken {
checkUserAuthSettings(pushToken: token)
}
}
}
}
func authorizationController(controller: ASAuthorizationController, didCompleteWithError error: Error) {
print("Sign in with Apple errored: \(error)")
}
@objc func startSignInWithAppleFlow() {
let nonce = randomNonceString()
currentNonce = nonce
let appleIDProvider = ASAuthorizationAppleIDProvider()
let request = appleIDProvider.createRequest()
request.requestedScopes = [.fullName, .email]
request.nonce = sha256(nonce)
let authorizationController = ASAuthorizationController(authorizationRequests: [request])
authorizationController.delegate = self
authorizationController.presentationContextProvider = self
authorizationController.performRequests()
}
private func randomNonceString(length: Int = 32) -> String {
precondition(length > 0)
let charset: Array<Character> = Array("0123456789ABCDEFGHIJKLMNOPQRSTUVXYZabcdefghijklmnopqrstuvwxyz-._")
var result = ""
var remainingLength = length
while remainingLength > 0 {
let randoms: [UInt8] = (0 ..< 16).map { _ in
var random: UInt8 = 0
let errorCode = SecRandomCopyBytes(kSecRandomDefault, 1, &random)
if errorCode != errSecSuccess {
fatalError("Unable to generate nonce. SecRandomCopyBytes failed with OSStatus \(errorCode)")
}
return random
}
randoms.forEach { random in
if remainingLength == 0 {
return
}
if random < charset.count {
result.append(charset[Int(random)])
remainingLength -= 1
}
}
}
return result
}
@available(iOS 13, *)
private func sha256(_ input: String) -> String {
let inputData = Data(input.utf8)
let hashedData = SHA256.hash(data: inputData)
let hashString = hashedData.compactMap {
return String(format: "%02x", $0)
}.joined()
return hashString
}
}
func makeUIView(context: Context) -> ASAuthorizationAppleIDButton {
let button = ASAuthorizationAppleIDButton(type: .signIn, style: .black)
button.addTarget(context.coordinator,action: #selector(Coordinator.startSignInWithAppleFlow),for: .touchUpInside)
return button
}
func updateUIView(_ uiView: ASAuthorizationAppleIDButton, context: Context) {
}
}
Я не понимаю, почему документ не может быть создан. В консоли я вижу nil.
Пожалуйста, помогите решить эту проблему.
Обновлено. Код ниже - это простая функция для создания пользовательского документа в хранилище в моем приложении.
func signup(username: String, email: String, password: String, imageData: Data, completed: @escaping(_ user: User) -> Void, onError: @escaping(_ errorMessage: String) -> Void) {
if !username.isEmpty && !email.isEmpty && !password.isEmpty && !imageData.isEmpty {
AuthService.signupUser(username: username, email: email, password: password, imageData: imageData, onSuccess: completed, onError: onError)
} else {
if username == "" {
errorString = "Please enter your name"
onError(errorString)
// showAlert = true
}
if email == "" {
errorString = "Please enter yor valid email"
onError(errorString)
// showAlert = true
}
if password == "" {
errorString = "Please create password"
onError(errorString)
// showAlert = true
}
if image == Image(IMAGE_USER_PLACEHOLDER) {
errorString = "Please upload your avatar"
onError(errorString)
// showAlert = true
}
}
}
и вот метод AuthService.signupUser
static func signupUser(username: String, email: String, password: String, imageData: Data, onSuccess: @escaping(_ user: User) -> Void, onError: @escaping(_ errorMessage: String) -> Void) {
//Firebase.createAccount(username: username, email: email, password: password, imageData: imageData)
Auth.auth().createUser(withEmail: email, password: password) { (authData, error) in
if error != nil {
print(error!.localizedDescription)
onError(error!.localizedDescription)
return
}
guard let userId = authData?.user.uid else { return }
let storageAvatarUserId = Ref.STORAGE_AVATAR_USERID(userId: userId)
let metadata = StorageMetadata()
metadata.contentType = "image/jpg"
StorageService.saveAvatar(userId: userId, username: username, email: email, imageData: imageData, metadata: metadata, storageAvatarRef: storageAvatarUserId, onSuccess: onSuccess, onError: onError)
}
}
Я знаю, что вход в систему Apple не может принимать изображения пользователей, и это нормально - мой облачный триггер заполняет это поле в документе users uid и в моем приложении, если user avatar = nil - это требует универсального графического изображения, это нормально, новый разум. А это пользовательский файл
import Foundation
struct User: Encodable, Decodable {
var uid: String
var email: String
var profileImageUrl: String
var username: String
var bio: String
var keywords: [String]
var status: String?
}
мои правила безопасности в firebase просты, вот они
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if request.auth != null;
}
}
}
