1、第一次登录的时候前端调后端的登陆接口发送用户名和密码
2、后端收到请求验证用户名和密码验证成功就给前端返回一个token
3、前端拿到token将token存储到localStorage和vuex中并跳转路由页面
4、前端每次跳转路由就判断 localStroage 中有无 token 没有就跳转到登录页面有则跳转到对应路由页面
5、每次调后端接口都要在请求头中加token
6、后端判断请求头中有无token有token就拿到token并验证token验证成功就返回数据验证失败例如token过期就返回401请求头中没有token也返回401
7、如果前端拿到状态码为401就清除token信息并跳转到登录页面
. . . . 实操代码
1.login页(账号密码登录完成后将后台返回的token储存到本地)最后附上了登录页完整代码
handleSubmit(e) {var that this;this.userName this.userName.trim();this.password this.password.trim();if (this.userName this.password ) {that.$message.warning(账号和密码无内容);return;}if (this.userName ) {that.$message.warning(账号无内容);return;}if (this.password ) {that.$message.warning(密码无内容);return;}var username document.getElementById(username).value;var password document.getElementById(password).value;e.preventDefault();this.form.validateFields((err, values) {//这一步将用户名储存在vuex ||||||||||目前域账号和用户名都是写一样了||||||||||||||||||||||||||||||||||||||||||||||||axios.post(this.$store.state.windowCONTENT sysConfig/getUserRole, {loginUser: this.userName,}).then((res) {if (res.data.success 0) {//有权限this.$store.state.loginUser this.userName;this.$store.state.userName this.userName;this.$store.state.roleCode res.data.data.roleCode;//存入tokenlocalStorage.setItem(token,JSON.stringify(res.data.data.token));// console.log(res.data.data,this.$store.state.roleCode);if (!err) {this.$router.push(/layout);this.$message.success(登陆成功);}} else {//无权限this.$message.error(res.data.data);}});});},2.marn.js配置请求拦截器每次请求携带token后端进行验证配置响应拦截器根据后端验证返回的结果判断token是否过期
import babel-polyfill;
import Vue from vue;
import App from ./App.vue;
import router from ./router;
import store from ./store;
import { Button, message } from ant-design-vue;
import Antd from ant-design-vue;
import ant-design-vue/dist/antd.css;
import zh_CN from ant-design-vue/lib/locale-provider/zh_CN;
import moment from moment;
import moment/locale/zh-cn;
import ./assets/iconfont/iconfont;
import axios from axios;Vue.component(Button.name, Button);Vue.config.productionTip false;Vue.use(Antd);
Vue.prototype.$message message;// 设置axios全局默认的BASE-URL 只要设置了全局的默认base_url以后的请求会自动拼接上base_url
//axios.defaults.baseURL http://localhost:8888/api/private/v1/// 配置axios的请求拦截器-(每次在请求头上携带后台分配的token-后台判断token是否有效等问题)
axios.interceptors.request.use(function(config) {// 在发送请求之前做些什么// console.log(请求到了哟, config.headers.Authorization)// 统一的给config设置 tokenconfig.headers.Authorization JSON.parse(localStorage.getItem(token));config.headers[Token] JSON.parse(localStorage.getItem(token));return config;},function(error) {// 对请求错误做些什么return Promise.reject(error);}
);//响应拦截器 与后端定义状态是100时候是错误 跳转到登录界面
axios.interceptors.response.use(function (response) {// 对响应数据做点什么console.log(response)//当返回信息为未登录或者登录失效的时候重定向为登录页面if (response.data.status 100 || response.data.message 用户未登录或登录超时请登录) {router.push({path: /login,querry: { redirect: router.currentRoute.fullPath }//从哪个页面跳转})message.warning(response.data.message);}return response;
}, function (error) {// 对响应错误做点什么return Promise.reject(error)
})moment.locale(zh-cn);
new Vue({zh_CN,router,watch: {// 监听路由变化$route.path: function(newVal, oldVal) {console.log(new_path ${newVal}, old_path ${oldVal});},},store,render: (h) h(App),
}).$mount(#app);
3.router.js配置导航守卫有token或者是去登录页就通过否则定向到登录页
import Vue from vue
import VueRouter from vue-router
import Home from ../views/Home.vue
import Layout from ../components/Layout.vue
import Login from ../components/Login.vueVue.use(VueRouter)const routes [{path: /,redirect: login},{path: /login,name: Login,component: Login},{path: /layout,name: Layout,component: Layout},{path: /about,name: About,// route level code-splitting// this generates a separate chunk (about.[hash].js) for this route// which is lazy-loaded when the route is visited.component: () import(/* webpackChunkName: about */ ../views/About.vue)}
]const router new VueRouter({routes
})// to 到哪去
// from 从哪来
// next 是否放行 next() 放行 next(/login) 拦截到登录
// 如果准备去登录, 不需要拦截
// 如果已经登录过了, 有token, 不需要拦截
// 如果不是去登陆, 且没有 token, 拦截到登录页
router.beforeEach((to, from, next) {const token JSON.parse(localStorage.getItem(token));console.log(token);// console.log(to)if (to.path /login || token) {next()} else {next(/login)}
})export default router
4.退出清除本地储存的token
//退出登录signOut() {console.log(点击了退出, this.$route.query.sessionId);localStorage.clear(token);this.$route.push(/)//将vuex的数据初始化和清除默认的数据},. . . . . .
完整登录页
