我在我的应用程序中使用 Auth Context Provider，它在此文件中初始化：

authState.js

import React, { useReducer, createContext, useContext } from "react";
import authReducer from "./authReducer";

const initialState = {
  user: null,
};

const AuthContext = createContext();

export const AuthStateProvider = ({ children }) => {
  const [state, dispatch] = useReducer(authReducer, initialState);

  return (
    <AuthContext.Provider value={[state, dispatch]}>
      {children}
    </AuthContext.Provider>
  );
};

export const useAuthContext = () => useContext(AuthContext);

然后将此上下文导入 App.js 以获取用户身份验证详细信息：

App.js

...
...
import { useAuthContext } from './context/auth/authState';
...
...
const [{ user }, authDispatch] = useAuthContext();

我在 const [{ user }, authDispatch] = useAuthContext(); 行收到错误。
