封装 axios+promise通用请求函数操作

我就废话不多说了，大家还是直接看代码吧~

import axios from "axios";
import baseUrl from "../../setBaseUrl";
axios.defaults.baseURL = baseUrl;
import { Loading, Message } from "element-ui";
const loadingOptions = {
 lock: true,
 text: "拼命加载中",
 spinner: "el-icon-loading",
 background: "rgba(0, 0, 0, 0.7)"
};
if (localStorage.token) {
 axios.defaults.headers.common["x-token"] = localStorage.token;
}
const Http = {
 get: function(url: string, data: any, isLoading: boolean) {
  if (localStorage.token) {
   axios.defaults.headers.common["x-token"] = localStorage.token;
  }
  let loading: any;
  if (isLoading) {
   loading = Loading.service(loadingOptions);
  }
  return new Promise<any>((resolve, reject) => {
   axios
    .get(url, { params: data })
    .then(function(res) {
     if (isLoading) {
      loading.close();
     }
     if (res.data.code === 200) {
      resolve(res.data.data);
     } else {
      // console.warn("Http error Info ===> ", res.data);
      reject(res.data.message);
     }
    })
    .catch(function(err) {
     if (isLoading) {
      loading.close();
     }
     // console.warn("Http error Info ===> ", err);

     });

   });
  });
 }
};
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？

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))
  })
 },
