问题描述
在我的项目中，当用户登录时，我使用触发器在 Firestore 中创建用户文档。这很棒 - 一切都非常适合 Google 登录和 Facebook 登录。
这是这个触发器：
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 })
})
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>) { }
}
但是当我尝试在用户使用 Apple 的 Swig in 登录时创建文档时，这不起作用。在 Firebase 身份验证下的 Firebase 控制台中，我可以看到新用户，但在 Firestore 中，根本没有显示任何文档。
import Foundation
import SwiftUI
import AuthenticationServices

self._showSheet = showSheet
}
func makeCoordinator() -> AppleAuthView.Coordinator {
return AppleAuthView.Coordinator(showAnimation: self.$showAnimation,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.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) {
}
}
我不明白为什么无法创建文档。在控制台中，我可以看到 nil。
请帮助解决此问题。
已更新。 下面的代码 - 是在我的应用程序的 firestore 中创建用户文档的简单功能
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
}
}
}
这里是 AuthService.signupUser 方法
static func signupUser(username: String,onSuccess: @escaping(_ user: User) -> Void,onError: @escaping(_ errorMessage: String) -> Void) {
//Firebase.createAccount(username: username,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,Metadata: Metadata,storageAvatarRef: storageAvatarUserId,onSuccess: onSuccess,onError: onError)
}
}
我知道苹果登录无法获取用户图像，这没关系 - 如果用户头像 = nil，我的云触发器会在文档用户 uid 和我的应用程序中填写此字段 - 它需要通用剪贴画，没关系，更新的想法。 这是用户文件
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?
}
我在 firebase 中的安全规则很简单，在这里
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read,write: if request.auth != null;
}
}
}
解决方法
这个问题是 - Apple 没有获得用户名。 问题已解决。
