我的代码:
import React, { useState, useContext, useEffect } from "react";
import HeaderComponent from '../../components/header';
import { StoreContext } from '../../store';
import NotAuthView from '../../components/notAuth-view'
const RequiredAuth = (Component) => props => {
const { authFlag } = useContext(StoreContext)
if (!authFlag) {
return <NotAuthView />
}
return <Component {...props} />
}
export default RequiredAuth
import React,{useState,useContext,useffect}来自“React”;
从“../../components/header”导入HeaderComponent;
从“../../store”导入{StoreContext};
从“../../components/notAuth视图”导入NotAuthView
const RequiredAuth=(组件)=>props=>{
const{authFlag}=useContext(StoreContext)
如果(!authFlag){
返回
}
返回
}

有人有办法解决这个问题吗?非常感谢 我已经解决了这个问题! 感谢@lissettdm和@VietDinh。
这是我使用RequiredAuth时出现的问题。您如何使用RequiredAuth HOC?RequiredAuth(组件)(道具)?你能展示一下你是如何使用RequiredAuth的吗?你能分享一下你是如何解决这个问题的吗?
