我正在使用 vuex 进行状态管理这是我的 vuex 代码，

这里我的逻辑是，如果令牌存在于本地存储中，那么它将设置 isAuthenticated 为 true，这样就可以很容易地检查路由。但是有些它是如何不起作用的。

import axios from "axios";
import router from "../../router";

const state = {
  token: localStorage.getItem("tkn") || "",
  isAuth: false,
};

const getters = {
  isAuthenticated: (state) => !!state.token,
  authStatus: (state) => state.isAuth,
};

const actions = {
  login({ commit }, loginData) {
    // commit('auth_request')
    axios
      .post("/api/adminuser/auth/login", loginData)
      .then((resp) => {
        console.log(resp);
        localStorage.setItem("tkn", resp.data.token);

        axios.defaults.headers.common["Authorization"] = resp.data.token;

        commit("setToken", resp.data.token);

        router.push("/");
      })
      .catch((err) => {
        console.log(err);

        commit("authError", err);
        localStorage.removeItem("token");
      });
  },
};

const mutations = {
  setToken: (state, token) => ((state.token = token), (state.isAuth = true)),
  authError: (state) => (state.isAuth = false),
};

export default {
  state,
  getters,
  actions,
  mutations,
};

这是我的路由器代码

import Vue from "vue";
import VueRouter from "vue-router";
import auth from "../store/modules/auth.js";

Vue.use(VueRouter);

const routes = [
  {
    path: "/signin",
    name: "signin",
    component: () => import("../components/Authentication/Signin.vue"),
  },

  {
    path: "/",
    name: "dashboard",
    component: () => import("../components/Dashboard/Dashboard.vue"),
    meta: {
      requiresAuth: true,
    },
  },
];

const router = new VueRouter({
  mode: "history",
  routes,
});

router.beforeEach((to, from, next) => {
  if (to.name !== "signin" && auth.getters.isAuthenticated == false)
    next({ name: "signin" });
  else next();
});


export default router;

目前，如果我登录仍然可以进入登录页面，甚至可以在没有身份验证的情况下进入仪表板。

请制作如下函数，在某个文件中说 helper.js 并在 main.js 中初始化它

助手.js

import axios from 'axios';
export function initialize(store, router) 
{  router.beforeEach((to,from,next)=>{ 
   const requiresAuth= to.matched.some(record=>record.meta.requiresAuth)
   const currentUser = store.state.isAuthenticated;
   if(requiresAuth && !currentUser){ next('/signin');} 
   else if(to.path=='/signin' && currentUser){ next('/')}
   else { next()}
  })
}

在你的 main.js

import {initialize} from './helper';
import router from './router'
import store from './store'
initialize(store, router);

登录页面

methods: {
...mapActions(["login"]),
loginUser: function(event) {
       event.preventDefault();
       this.login({ email: this.email, password: this.password })
           .then(()=>{ this.$router.replace({name:'dashboard'})
                        //forward to this path after login
                     }).catch(()=>{console.log('login fail')   });
      }
},

您应该在使用之前创建商店

// auth.js
import Vue from 'vue'
import Vuex from 'vuex'
import router from "../../router";

Vue.use(Vuex)
// ....
export default new Vuex.Store({
 state,
 getters,
 actions,
 mutations,
});

否则 auth.getters.isAuthenticated将是函数，而不是 vuex getter。
