如何在firebase身份验证中为.reauthenticateWithCredential()创建凭据参数？

var user = firebase.auth().currentUser;
var credential = user.credential;

var email = "user@example.com";
var password = "password";
var credential = firebase.auth.EmailAuthProvider.credential(email, password);

var phoneNumber = "+1234567890";
var verificationCode = "123456";
var credential = firebase.auth.PhoneAuthProvider.credential(verificationId, verificationCode);

var googleProvider = new firebase.auth.GoogleAuthProvider();
var credential = googleProvider.credential(idToken, accessToken);

var facebookProvider = new firebase.auth.FacebookAuthProvider();
var credential = facebookProvider.credential(accessToken);

user.reauthenticateWithCredential(credential)
  .then(function() {
    // 身份验证成功
  })
  .catch(function(error) {
    // 身份验证失败
  });
