我正在开发我的项目与reactjs和redux,所以我想显示不同的链接在导航栏时,我登录或注销。当我点击登录它的确定和一切工作正常,但当我点击注销它不改变导航栏automaticclly,我必须刷新页面。任何人可以帮助我吗?这里是我的Navbar.js:

import React, { useEffect, useState} from 'react'
import { useDispatch, useSelector } from 'react-redux';
import { Link,useHistory } from 'react-router-dom';
import { selectAccessToken } from '../features/authentications/authenticationsSlice';

import axios from 'axios';

import './Navbar.css';

export const Navbar = (props) => {
   const [loggedIn , setLoggedIn] = useState(false)

   let accessToken = useSelector(selectAccessToken);
   const [token, setToken] = useState(accessToken)
   const dispatch = useDispatch()

   const [loggedOut, setLoggedOut] = useState([]);

   const [errors, setErrors] = useState([]);

   const LOGOUT_URL = 'http://127.0.0.1:8000/accounts_api/v1/dj-rest-auth/logout/';

   const history = useHistory()

   const removeTokens  = async () => {

      try {
         const response = await axios.post(`${LOGOUT_URL}`, { headers: { "Authorization": `Bearer ${accessToken}` }})
         const data = response.data;
         setLoggedOut(data)      

         console.log("data: ", data)
      }
      catch (err) {
         console.log('err', err)
         setErrors(err)
      }

    }

  const handleLogout = async () => {
   await logout();
   history.push("login/");
 };

  const logout = () => {

      removeTokens()
      localStorage.removeItem("access_token")
      localStorage.removeItem("refresh_token")
      console.log('localstrorage token after logout: ', localStorage.getItem("access_token"))
      setLoggedIn(false);
      accessToken = null

      console.log('accesstoken after logout:', accessToken)
 }

   if (accessToken) {
      return (
         <nav>
            <ul className="menu">

            <li className="logo"> My logo </li>

            <li className="item">
            <Link to="/">
               articles
            </Link>

            </li>
            <li>
               <Link to="/topics">Topics</Link>
            </li>

            <li>
               <Link to="/articles">Seconds</Link>
            </li>

            <li className="item">
               <Link to="/management">
                  management
               </Link>
             </li>

            <li className="item">
               <Link to="/" onClick={handleLogout}>
                  Logout
               </Link>
            </li>

            </ul>

         </nav>
     )
   } else if (!accessToken) {

      return (
         <nav>
            <ul className="menu">

            <li className="logo"> My logo </li>

            <li className="item">
            <Link to="/">
               articles
            </Link>

            </li>
            <li>
               <Link to="/topics">Topics</Link>
            </li>

            <li>
               <Link to="/articles">Seconds</Link>
            </li>

            <li className="item">
         <Link 
            to="/login" 
            onClick={() => {
                 localStorage.setItem("access_token", true);
                 setLoggedIn(true);
               }
             }
            >
            Login
         </Link>
      </li>

            </ul>

         </nav>
     )
   }

您不能在注销时将accessToken设置为null。此accessToken是redux状态中的访问标记的引用。redux状态仍包含访问标记。

accessToken = null

您必须创建action,并将redux中的accessToken设置为null,然后在注销时调用该函数。
