useAuth返回的context和 有关系吗？是说一定要在 包含内的元素，使用useAuth返回的context就是<AuthContext.Provider children={children} value={{user, login, register, logout}} />中的value吗？？？？

const AuthContext = React.createContext<{
    user: User |null;
    login:(form:AuthForm) => Promise<void>;
    register:(form:AuthForm) => Promise<void>;
    logout:() => Promise<void>;
}|undefined>(undefined)
AuthContext.displayName = 'AuthContext'

export const AuthProvider = ({children}: {children: ReactNode}) => {
    const [user, setUser] = useState<User | null>(null)
    const login = (form: AuthForm) => auth.login(form).then(user => setUser(user))
    const register = (form: AuthForm) => auth.register(form).then(user => setUser(user))
    const logout = () => auth.logout().then(() => setUser(null))

    return <AuthContext.Provider children={children} value={{user, login, register, logout}} />
}

export const useAuth = () => {
    const context = React.useContext(AuthContext)
    if(!context){
        throw new Error('useAuth必须在AuthProvider中使用')
    }
    return context
}
