toke验证

需要准备的东西：Vue+axios+Vuex+Vue-router 1.在login.vue中通过发送http请求获取token

//根据api接口获取token var url = this.HOST + "/session"; this.$axios.post(url, { username: this.loginForm.username, password: this.loginForm.pass }).then( res => { // console.log(res.data); this.$message.success( '登录成功'); let data = res.data; //根据store中set_token方法将token保存至localStorage/sessionStorage中，data["Authentication-Token"]，获取token的value值 this.$store.commit( 'set_token', data[ "Authentication-Token"]); if (store.state.token) { this.$router.push( '/') console.log(store.state.token) } else { this.$router.replace( '/login'); } }).catch( error => { // this.$message.error(error.status) this.loading = false this.loginBtn = "登录" this.$message.error( '账号或密码错误'); // console.log(error) }) 2.在store.js中对token状态进行监管 import Vue from 'vue' import Vuex from 'vuex' Vue.use(Vuex) export default new Vuex.Store({ state:{ token: '' }, mutations:{ set_token(state, token) { state.token = token sessionStorage.token = token }, del_token(state) { state.token = '' sessionStorage.removeItem( 'token') } } }) 3.在router/index.js中 // 页面刷新时，重新赋值token if (sessionStorage.getItem( 'token')) { store.commit( 'set_token', sessionStorage.getItem( 'token')) } const router = new Router({ mode: "history", routes }); router.beforeEach( (to, from, next) => { if (to.matched.some( r => r.meta.requireAuth)) { //这里的requireAuth为路由中定义的 meta:{requireAuth:true}，意思为：该路由添加该字段，表示进入该路由需要登陆的 if (store.state.token) { next(); } else { next({ path: '/login', query: { redirect: to.fullPath} }) } } else { next(); } }) 4.在main.js中定义全局默认配置：

Axios.defaults.headers.common['Authentication-Token'] = store.state.token; 5.在src/main.js添加拦截器 // 添加请求拦截器 Axios.interceptors.request.use( config => { // 在发送请求之前做些什么 //判断是否存在token，如果存在将每个页面header都添加token if(store.state.token){ config.headers.common[ 'Authentication-Token']=store.state.token } return config; }, error => { // 对请求错误做些什么 return Promise.reject(error); }); // http response 拦截器 Axios.interceptors.response.use( response => { return response; }, error => { if (error.response) { switch (error.response.status) { case 401: this.$store.commit( 'del_token'); router.replace({ path: '/login', query: { redirect: router.currentRoute.fullPath} //登录成功后跳入浏览的当前页面 }) } } return Promise.reject(error.response.data) }); ------------------------------------------------------------------------------------ ...................完成以上步骤就可以了.......................... ------------------------------------------------------------------------------------ 转载来源：https://blog.csdn.net/qq_34825875/article/details/79569579
