如何使用 JavaScript（Firebase 身份验证）根据用户的 UID 登录用户

Question

我想根据用户 ID 登录一个用户并拒绝其余的用户。

这是我目前尝试过的：

function myFunction() {
    let email = document.getElementById("email").value
    console.log(email)
    let password = document.getElementById("password").value
    console.log(password)
    firebase.auth().signInWithEmailAndPassword(email, password).then((user) => {
        console.log("signed in", user)
        firebase.auth().signOut();
    })
    .catch((error) => {
        console.log("error")
        var errorCode = error.code;
        var errorMessage = error.message;
        console.log(errorCode, errorMessage)
        var x = document.getElementById("errorLogin");
        x.style.display = "block";
    })
  }
