帐户创建后 Firebase 返回用户对象 [英] Firebase Returning user object after account creation
问题描述
我试图在 Firebase 中创建一个用户,然后在网络服务器上的数据库中创建一个用户配置文件.我已经实现了以下代码,它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.有没有办法在调用 createUserWithEmailAndPassword 时返回用户对象?
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?
我试图实现一个 firebase.auth().onAuthStateChanged
函数,但我收到一个超时错误

如果您还没有收集到,这是针对网络应用程序的.
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,您应该这样做:
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
});
正如这里描述的那样:
https://firebase.google.com/docs/参考/js/firebase.auth.Auth#createUserWithEmailAndPassword
退货非空 firebase.Promise 包含非空 firebase.User
Returns non-null firebase.Promise containing non-null firebase.User
