在 Firebase 中创建用户时出错？

Question

    var rootRef = firebase.database().ref();
    var vasu = rootRef("https://<my app>.firebaseio.com")
rootRef.createUser({
  email    : "swamy1234@gmail.com",
  password : "swamy1234"
}, function(error, userData) {
  if (error) {
    console.log("Error creating user:", error);
  } else {
    console.log("Successfully created user account with uid:", userData.uid);
  }
});

在浏览器中运行时出现错误

error : Uncaught TypeError: rootRef is not a function
    at (index):771
(anonymous) @ (index):771

请给我一个正确的代码

Answer 1

使用以下代码使用电子邮件地址和密码登录用户

firebase.auth().createUserWithEmailAndPassword({
      email    : "swamy1234@gmail.com",
      password : "swamy1234"
    }).catch(function(error) {
  // Handle Errors here.
  var errorCode = error.code;
  var errorMessage = error.message;
  // ...
});

var rootRef = firebase.database().ref();
let newTransactionRef = rootRef.child('user').push()
// here user is your database ref in which you may want to insert a new user data
newTransactionRef.set('user').push({
      email    : "swamy1234@gmail.com",
      password : "swamy1234"
    }).then(function (userData) {
    // successfully created
    console.log("Successfully created user account with uid:", userData.uid);
}).catch(function(error){
  //error
  console.log("Error creating user:", error);
})
