在main.js中引入axios

import Vue from "vue";
import App from "./App.vue";
import router from "./router";
import axios from "axios";// 挂载后台数据
Vue.prototype.$http = axios;
axios.defaults.baseURL = "http://127.0.0.1:8888/api/private/v1/";
// 请求拦截
axios.interceptors.request.use((config) => {// 添加请求令牌config.headers.Authorization = window.sessionStorage.getItem("token");return config;
});
