创建帐户后，Firebase返回用户对象

问题描述

我正在尝试在Firebase中创建用户，然后在Web服务器上的数据库中创建用户配置文件.我实现了以下代码，可以很好地创建用户.但是我不确定如何接收用户ID(我需要一个唯一ID)来创建数据库结构.调用createUserWithEmailAndPassword时，是否可以返回用户对象?

Im trying to create a user within Firebase and then create a user profile within the database on a web server. I have implemented the following code which creates the user quite nicely. However im not sure on how to receive the user id (which i need for a unique ID) to create the database structure. Is there a way to return a user object when the createUserWithEmailAndPassword is called?

我尝试实现firebase.auth().onAuthStateChanged函数，但是随后收到超时错误

I have tried to implement a firebase.auth().onAuthStateChangedfunction but i then receive a timeout error

如果您还没有收集到，则用于网络应用程序.

If you havn't gathered this is for a web app.

<script>
function createUser() {
var Result = "true";
var textUser = document.getElementById('userName').value;
var textPassword = document.getElementById('userPassword').value;
var textAccountID = document.getElementById('accountRef').value;
var textDateCreated = document.getElementById('dateCreated').value;
var textDisplayName = document.getElementById('displayName').value;
var UID;

firebase.auth().createUserWithEmailAndPassword(textUser, textPassword).catch(function(error) {
  // Handle Errors here.
  var errorCode = error.code;
  var errorMessage = error.message;
  return Result = "false";
  // ...
});

writeUserData(UID, textDisplayName, textAccountID, textDateCreated);

return Result;

}

function writeUserData(userId, displayName, accountID, dateCreated) {
  firebase.database().ref('User/' + userId).set({
  userId:{
    AccountID: accountID,
    Created: dateCreated,
    Name: displayName}
  });
}


</script>

推荐答案

为了在客户端获取用户ID，您应该执行以下操作:

In order to get the user id in the client side you should do this:

firebase.auth().createUserWithEmailAndPassword(textUser, textPassword)
.then(function(user){
  console.log('uid',user.uid)

  //Here if you want you can sign in the user
}).catch(function(error) {
    //Handle error
});

如此处所述:

退货非空Firebase.Promise包含非空Firebase.User

Returnsnon-null firebase.Promise containing non-null firebase.User
