Flutter:Firebase身份验证无需自动登录即可创建用户 [英] Flutter: Firebase Authentication Create User Without Automatically Logging In
问题描述
我的flutter应用程序中具有使用Firebase身份验证的用户管理功能.我可以使用 firebase_auth
的 createUserWithEmailAndPassword()
函数注册新的用户帐户.
I have a user management feature in my flutter app that uses firebase authentication. I can register new user accounts using firebase_auth
's createUserWithEmailAndPassword()
function.
return await FirebaseAuth.instance.
createUserWithEmailAndPassword(email: email, password: password);
问题是注册成功后,即使我已经登录,它也会自动将我的 FirebaseAuth
实例认证为新用户.
The problem is when the registration is successful it automatically authenticates my FirebaseAuth
instance as the new user even though I am already logged in.
我遇到了以下答案: Firebase淘汰了当前用户 ,但这是在javascript和api稍有不同.
I came across this answer: Firebase kicks out current user but it's in javascript and has a slightly different api.
我该如何在飞镖上做同样的事情?
How can I do the equivalent in dart?
推荐答案
已更新: firebase_core ^ 0.5.0
和 firebase_auth ^ 0.18.0 + 1
已弃用了adadion的 answer 中共享的一些旧类.
Updated: firebase_core ^0.5.0
and firebase_auth ^0.18.0+1
has deprecated some of the old classes as shared in adadion's answer.
以下是为 firebase_core ^ 0.5.1
和 firebase_auth ^ 0.18.2
更新的代码.
Below is code updated for firebase_core ^0.5.1
and firebase_auth ^0.18.2
.
static Future<UserCredential> register(String email, String password) async {
FirebaseApp app = await Firebase.initializeApp(
name: 'Secondary', options: Firebase.app().options);
try {
UserCredential userCredential = await FirebaseAuth.instanceFor(app: app)
.createUserWithEmailAndPassword(email: email, password: password);
}
on FirebaseAuthException catch (e) {
// Do something with exception. This try/catch is here to make sure
// that even if the user creation fails, app.delete() runs, if is not,
// next time Firebase.initializeApp() will fail as the previous one was
// not deleted.
}
await app.delete();
return Future.sync(() => userCredential);
}
原始答案
我试用了Firebase身份验证api,目前可以使用的解决方案是:
I experimented with the firebase authentication api and my current working solution is:
// Deprecated as of `firebase_core ^0.5.0` and `firebase_auth ^0.18.0`.
// Use code above instead.
static Future<FirebaseUser> register(String email, String password) async {
FirebaseApp app = await FirebaseApp.configure(
name: 'Secondary', options: await FirebaseApp.instance.options);
return FirebaseAuth.fromApp(app)
.createUserWithEmailAndPassword(email: email, password: password);
}
从本质上讲,这归结于创建 FirebaseAuth
的新实例,因此从 createUserWithEmailAndPassword()
进行的自动登录不会影响默认实例.
Essentially it comes down to creating a new instance of FirebaseAuth
so the automatic login from createUserWithEmailAndPassword()
do not affect the default instance.
