我尝试在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。我已经实现了以下代码,可以非常好地创建用户。但是我不确定如何接收用户ID(我需要一个唯一的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?
我试图实现firebase.auth().onAuthStateChanged
函数但我收到超时错误
如果您没有收集,这是一个网络应用程序。
<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>

为了在客户端获取用户ID,您应该这样做:
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
});
如下所述:
https://firebase.google.com/docs/reference/js/firebase.auth.Auth#createUserWithEmailAndPassword
返回 非null firebase.Promise包含非null firebase.User

好像firebase在此方法上做了一些更改。接受的解决方案需要一点修复:
firebase.auth().createUserWithEmailAndPassword(textUser, textPassword)
.then(function(data){
console.log('uid',data.user.uid)
//Here if you want you can sign in the user
}).catch(function(error) {
//Handle error
});
现在您可以通过data.user
来访问该用户。希望这会有所帮助:)

createUserWithEmailAndPassword()
函数返回一个所谓的Promise,它有方法catch()
和then()
。您已经在使用catch()
来处理问题。要处理&#34;非问题&#34;,您需要使用then()
:
firebase.auth().createUserWithEmailAndPassword(textUser, textPassword)
.then(function(user) {
console.log(user); // see https://firebase.google.com/docs/reference/js/firebase.User
})
.catch(function(error) {
// Handle Errors here.
var errorCode = error.code;
var errorMessage = error.message;
return Result = "false";
// ...
});

firebase.auth().createUserWithEmailAndPassword(email.value, password.value).then(function (user) {
//var user = firebase.auth().currentUser;
alert('Cadastro feito com sucesso!', "success");
console.log("New user Id: "+ user.uid);
}).catch(function (error) {
// Handle Errors here.
var errorCode = error.code;
var errorMessage = error.message;
// [START_EXCLUDE]
if (errorCode == 'auth/weak-password') {
alert('A senha é muito fraca.', "warning");
//alert('A senha é muito fraca.');
} else if (errorMessage == "The email address is already in use by another account.") {
errorMsg = "Esse email já está sendo usado por outra conta";
alert(errorMsg, "danger");
//alert(errorMessage);
}else{
alert(errorMessage);
}
// [END_EXCLUDE]
});
