Vue3中全局配置 axios 的两种方式

import Vue from "vue";
/* 第一步下载 axios 命令：npm i axios 或者yarn add axios 或者pnpm i axios */
/* 第二步引入axios */
import axios from 'axios'
// 挂载一个自定义属性$http
Vue.prototype.$http = axios
// 全局配置axios请求根路径(axios.默认配置.请求根路径)
axios.defaults.baseURL = 'http://yufei.shop:3000'

import axios from "axios";
import { Notification, MessageBox, Message } from "element-ui";
import store from "@/store";
import { getToken } from "@/utils/auth";
import errorCode from "@/utils/errorCode";
import Cookies from "js-cookie";
import VFrame from "../framework/VFrame.js";
import CONSTANT from '@/CONSTANT.js'
axios.defaults.headers["Content-Type"] = "application/json;charset=utf-8";
// 创建axios实例
const service = axios.create({
  // axios中请求配置有baseURL选项，表示请求URL公共部分
  baseURL: process.env.VUE_APP_BASE_API,
  // 超时
  timeout: 120000
});
// request拦截器
service.interceptors.request.use(
  config => {
    // 是否需要设置 token
    const isToken = (config.headers || {}).isToken === false;
    if (getToken() && !isToken) {

    }
    var cultureName = Cookies.get(CONSTANT.UX_LANGUAGE);
    if (cultureName) {
      config.headers[CONSTANT.UX_LANGUAGE] = cultureName; // 让每个请求携带自定义token 请根据实际情况自行修改
    }
