export default Http;补充知识：vuex刷新页面是store被更新，如何解决数据备份？补充知识：补充知识：vuex刷新页面是store被更新，如何解决数据备份？我用的方法很简单，在App.vue中的生命周期函数created中，监听页面刷新，在页面刷新的时候，将store的数据及时存储在sessionStorage中，然后刷新完毕后就可以将sessionStorage中的数据再取出来用
created () { //页面刷新store数据备份

if (localStorage.cmstoken) {

this.$router.replace("/data");

}else {

this.$router.replace("/");

}

if (sessionStorage.getItem("store") ) { //在页面加载时读取sessionStorage里的状态信息

this.$store.replaceState(Object.assign({}, this.$store.state,JSON.parse(sessionStorage.getItem("store"))))

}

window.addEventListener("beforeunload",()=>{ //在页面刷新时将vuex里的信息保存到sessionStorage里

sessionStorage.setItem("store",JSON.stringify(this.$store.state))

})
},
created () { //页面刷新store数据备份

if (localStorage.cmstoken) {

this.$router.replace("/data");

}else {

this.$router.replace("/");

}

if (sessionStorage.getItem("store") ) { //在页面加载时读取sessionStorage里的状态信息

this.$store.replaceState(Object.assign({}, this.$store.state,JSON.parse(sessionStorage.getItem("store"))))

}

window.addEventListener("beforeunload",()=>{ //在页面刷新时将vuex里的信息保存到sessionStorage里

sessionStorage.setItem("store",JSON.stringify(this.$store.state))

})
