我正在实现一个云功能来更新当前用户的密码。
基本上,我想要遵循的逻辑是:
(Client side)
0. Complete form and submit the data (current password and new password).
(Backend)
1. Get the current user email from the callable function context.
2. Re-authenticate the current user using the provided current password.
2.1. If success, change the password and send a notification email.
2.2. Else, throw an error.
这是我当前的代码:
const { auth, functions } = require("../../services/firebase");
...
exports.updatePassword = functions
.region("us-central1")
.runWith({ memory: "1GB", timeoutSeconds: 120 })
.https.onCall(async (data, context) => {
const { currentPassowrd, newPassword } = data;
const { email, uid: userId } = context.auth.token;
if (!userId) {
// throw ...
}
try {
//
// Problem: `firebase-admin` authentication doesn't include
// the `signInWithEmailAndPassword()` method...
//
await auth.signInWithEmailAndPassword(email, currentPassowrd);
await auth.updateUser(userId, {
password: newPassword,
});
sendPasswordUpdateEmail(email);
} catch (err) {
// ...
throw AuthErrors.cannotUpdatePassword();
}
});
我的问题是
firebase-admin
包不包含 signInWithEmailAndPassword
,我需要一种方法来处理这个问题,以检查我的函数内的“currentPassword”是否正确。
如果我所描述的方法不可行,我的另一种选择是在客户端使用 firebase sdk 更新密码,然后调用 firebase 函数发送通知电子邮件。
严格来说,您不需要在云函数中重新对用户进行身份验证:如果您在 Callable Cloud Function 中获得
context.auth.uid
的值,则意味着用户已在前端进行了身份验证,因此您可以安全地调用 updateUser()
方法。
如果您想处理用户打开设备并且有人更新密码时的情况(如您问题下的评论中所述),我建议您在前端使用
reauthenticateWithCredential()
方法,它使用新的凭据重新对用户进行身份验证。
执行以下操作:
import {
EmailAuthProvider,
getAuth,
reauthenticateWithCredential,
} from 'firebase/auth'
const email = auth.currentUser.email;
// Capture the password value
// e.g. via a pop-up window
const password = ...;
const auth = getAuth();
const credential = EmailAuthProvider.credential(
email,
password
);
await reauthenticateWithCredential(
auth.currentUser,
credential
);
// If no error is thrown, you can call the Callable Cloud Function, knowing the user has just re-signed-in.
