vue为单页面前端框架，清理缓存，常规的方式是添加html头部meta，如果逻辑里面是需要使用缓存的，这种方式不建议使用，代码片段如下：
<html manifest="IGNORE.manifest"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" /> <meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Expires" content="0" /> ......
第二种方式就是在文件名后添加随机数，可以在路由里面进行设置，但如果路由是需要带参数的，会有影响
const routes = [
{ path: ‘/‘, redirect: ‘/userInfo‘},
{ path: ‘/home‘,component:home},
{ path: ‘/login?123232‘, component: login, meta: {title: ‘登录‘}},
{ path: ‘/userInfo‘, component: userInfo, meta: { requiresAuth: true, title: ‘账号管理‘ }},
{ path: ‘/toggleIdentity‘,component:toggleIdentity, meta: { requiresAuth: true, title: ‘身份切换‘ }},
{ path: ‘/myTracks‘, component: myTracks, meta: { requiresAuth: true, title: ‘我的足迹‘ }},
// { path: ‘/applicationCenter‘, component: applicationCenter, meta: { requiresAuth: true, title: ‘应用中心‘}},
{ path: ‘/topicList‘, component: topicList, meta: { requiresAuth: true, title: ‘话题探讨‘ }},
{ path: ‘/topicList/:id‘, component: topicDetail, meta: {title: ‘话题详情‘}},
{ path: ‘/activityList‘, component: activityList, meta: { requiresAuth: true, title: ‘精彩活动‘ }},
{ path: ‘/interactionList‘, component: InteractionList, meta: { requiresAuth: true, title: ‘家校互动‘ }},
{ path: ‘/officeMsg‘, component: OfficeMsg , meta: { requiresAuth: true, title: ‘办公短信‘ }},
{ path: ‘/msgInfo/:messageId/:type/:smsMessageType/:keyTime‘, component: MsgInfo, meta: { requiresAuth: true, title: ‘详情‘ } },
{ path: ‘/sendMessage‘, component: SendMessage , meta: { requiresAuth: true, title: ‘发消息‘ }},
{ path: ‘/msgStatusReport/:messageId/:msgType/:keyTime‘, component: MsgStatusReport , meta: { requiresAuth: true, title: ‘状态报告‘ }},
{ path: ‘/commentList‘,component:commentList},
{ path: ‘/DPlayer/:id‘,component:DPlayer},
{ path: ‘/application‘, component: Application , meta: { requiresAuth: true, title: ‘应用‘ }}
];
第三种就是在vue项目里面进行代码添加后缀，以随机数的形式，进入。原理上和第二种方式相似，url地址变化，就不会有上次的缓存了。参考地址https://blog.csdn.net/yelin042/article/details/79763061
import store from ‘./vuex/store‘
import cookie from ‘./libs/cookie‘
// 路由预先判断
router.beforeEach((to, from, next) => {
// 首先判断是否已有用户登录信息userInfo
if (store.state.user.info) {
next()
} else {
// 强制给index.html 加上时间戳
if (document.URL.indexOf(‘index.html?t=‘) < 0) {
let timestamp = (new Date()).valueOf()
window.location.href = ‘/index.html?t=‘ + timestamp + ‘#‘ + to.fullPath
}
let ua = window.navigator.userAgent.toLowerCase()
// 判断微信客户端
if (ua.indexOf(‘micromessenger‘) > 1) {
// 首先获取授权cookie authid
let authid = cookie.get(‘authid‘)
if (authid) {
Vue.http.post(‘/index.php/weixin/Auth/auth‘, {authid: authid}).then((response) => {
let res = response.data
if (res.code === ‘04‘) {
cookie.del(‘authid‘)
window.location.href = ‘404.html‘
} else if (res.code === ‘01‘) {
store.dispatch(‘setUserInfo‘, res.userInfo)
next()
}
}, (response) => {})
} else {
// 强制跳转，授权登录，并设置cookie
window.location.href = ‘/index.php/weixin/Auth/redirect?redirect=‘ + encodeURIComponent(document.URL)
}
} else {
// 非微信客户端
Vue.http.post(‘/index.php/weixin/Auth/auth‘, {openid: cookie.get(‘openid‘)}).then((response) => {
let res = response.data
if (res.code === ‘04‘) {
cookie.del(‘authid‘)
next()
// window.location.href = ‘/index.php/weixin/Auth/redirect?redirect=‘ + encodeURIComponent(document.URL)
} else if (res.code === ‘01‘) {
store.dispatch(‘setUserInfo‘, res.userInfo)
next()
}
}, (response) => {})
}
}
})
