我在项目中使用 Firebase 身份验证，并且遇到了一个问题：使用
127.0.0.1localhost<!DOCTYPE html>
<html>
<body>
<button id="btn1">Log in/Sign up</button>
<button id="btn2" disabled>Sign Out</button>
<script type="module">
import { initializeApp } from "https://www.gstatic.com/firebasejs/10.9.0/firebase-app.js"
import { getAuth, GoogleAuthProvider, signInWithPopup, signOut} from "https://www.gstatic.com/firebasejs/10.9.0/firebase-auth.js"
const firebaseConfig = {
// my config
}
const app = initializeApp(firebaseConfig)
const auth = getAuth()
const provider = new GoogleAuthProvider()
async function SignIn() {
await signInWithPopup(auth, provider)
btn1.disabled = true
btn2.disabled = false
}
async function SignOut() {
await signOut(auth)
btn1.disabled = false
btn2.disabled = true
}
btn1.addEventListener('click', SignIn)
btn2.addEventListener('click', SignOut)
</script>
</body>
</html>
