vue项目微信端清理缓存问题解决

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：

manifest="IGNORE.manifest">
  
    
    
    
    
    
......

 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) => {})
    }
  }
})
