在使用firebase配置typescript时,我收到以下错误:Argument of type 'User | null' is not assignable to parameter of type 'User'. Type 'null' is not assignable to type 'User'.
- 错误在这里:auth. currentUser**我不清楚它是什么类型。
updateProfile(auth.currentUser, {
displayName: name
}
完整代码:
import { getAuth, createUserWithEmailAndPassword, signOut, onAuthStateChanged, signInWithEmailAndPassword, updateProfile } from "firebase/auth";
import { useEffect, useState } from "react";
import FirebaseInitialization from "../Firebase/Firebase.init";
FirebaseInitialization()
interface IUseFirebaseProps {
}
const UseFirebase: React.FunctionComponent<IUseFirebaseProps> = (props) => {
const [user, setUser] = useState({})
const [error, setError] = useState('')
const [admin, setAdmin] = useState(false)
const [isLoading, setIsLoading] = useState(true)
const auth = getAuth()
// REGISTER WITH EMAIL AND PASSWORD
const RegisterUser = (email: string, password:string, name:string, history: any) => {
setIsLoading(true)
createUserWithEmailAndPassword(auth, email, password)
.then((userCredential) => {
const newUser = { email, displayName: name };
setUser(newUser);
setError('')
updateProfile(auth.currentUser, {
displayName: name
}).then(() => {
}).catch((error) => {
});
history.replace('/');
})
.catch((error) => {
const errorMessage = error.message;
setError(errorMessage)
}).finally(() => setIsLoading(false));
}
return <h2>Firebase</h2>
};
export default UseFirebase;
我该怎么解决这个问题,有人能帮我吗?

按热度按时间xzv2uavs1#
auth.currentUser
的值可以是null
。在这种情况下,您可以直接从UserCredential
对象传递User
对象。请尝试如下所示重构代码:
