javascript - Firebase 身份验证异步等待

Question

我刚开始使用异步等待，我正在尝试在 firebase 中使用 Auth createUserWithEmailAndPassword。

注册

exports.signup = async (req, res) => {
    const { email, password, confirmPassword, handle } = req.body

    const newUser = {
        email,
        password,
        confirmPassword,
        handle
    }

    try {
        const response = await firebase.auth().createUserWithEmailAndPassword(newUser.email, newUser.password)
        const token = response.getIdToken()
        console.log('THIS IS THE RESPONSE', token)
        // return token
        return res.status(200).json({
            message: 'User Successfully Added!',
            token: token
        })

    } catch (err) {
        if (err.code === 'auth/email-already-in-use') {
            return res.status(400).json({
                message: 'Email already taken!'
            })
        } else {
            return res.status(500).json({
                message: 'Something went wrong, Please try again later'
            })
        }
    }
}

我的问题是，这实际上是在创建一个帐户，但总是返回 500 出现错误，请稍后重试

编辑:

console.log(err) 给出以下输出:

TypeError: response.getIdToken is not a function

我会尝试调查一下。

createUserWithEmailAndPassword 返回 Promise< UserCredential >而 getIdToken 是用户的方法 ( Documentation )

const response = await firebase.auth().createUserWithEmailAndPassword(newUser.email, newUser.password);
const token = await response.user.getIdToken(); // getIdToken is a method of user
console.log('THIS IS THE RESPONSE', token);
// return token
return res.status(200).json({
    message: 'User Successfully Added!',
    token: token
});
