看，田野里的玉米露出了笑脸，秋风吹过，闪烁着太阳的光芒，秋天是金色的。看满山的枫叶，红得就像一团火焰在熊熊燃烧，散发着生机，秋天是红色的。呵呵，我们都错了，秋天不是金黄的，也不是红色的，秋天是五颜六色的。
我就废话不多说了，大家还是直接看代码吧~

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))
})
},
以上这篇封装 axios+promise通用请求函数操作就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
