Vue中request.js封装及调用示例详解

import axios, { AxiosRequestConfig } from "axios";
import qs from "qs";
// 创建axios实例
const instance = axios.create({
  baseURL: process.env.VUE_APP_BASEURL,
  timeout: 6000,
  // headers: {
  //   "Content-Type": "application/x-www-form-urlencoded;charset=UTF-8",
  // token:
  //   "MTY1Mjk1Mjg4OC42ODM2Nzg0JjJkNzUyOWQwOWU3NTU2OTE0OTU4NzI3ODUxNzkwYTNjZGMwZmRjNjAzNGQ4MGE1YzFkODE1NGVmYzk4MmMyYjM=",
  // },
});
// 请求拦截器
instance.interceptors.request.use(
  (config) => {
    // 请求头和token判断等
    return config;
  },
  (err) => {
    return Promise.reject(err);
  }
);
//响应拦截器
instance.interceptors.response.use(
  (res) => {
    return res.data;
  },
