vue3 ts 封装axios,配置axios前置拦截器，让所有axios请求携带token

---

http.ts

import axios from 'axios' // 引入axios
import router from '@/router'
import Qs from 'qs'
import { ElMessage } from 'element-plus'


const { prefixBasePath } = require('../../../config/basePath')
axios.defaults.baseURL = prefixBasePath;

// 配置axios前置拦截器，作用是让所有axios请求携带token，后台需要token校验是否登录
axios.interceptors.request.use(config => {
  // 1.从缓存中获取到token,这里的Authorization时登录时你给用户设置token的键值
  let authorization = localStorage.getItem("Authorization");
  // 2.如果token不为null，那么设置到请求头中，此处哪怕为null，我们也不进行处理，因为后台会进行拦截
  if (authorization) {
  //后台给登录用户设置的token的键时什么，headers['''']里的键也应该保持一致
    config.headers['Authorization'] = authorization;
  }
  // 3.放行
  return config;
}, error => {
//失败后抛出错误
  Promise.reject(error);
})

//  *   --------------------  get请求  --------------------
// get请求
// 1、根据id查看一条信息
// 2、获取所有数据，展示表格数据
export function getOneOrAllData(url: any, params: any, hideTips: any) {
  return new Promise((resolve, reject) => {
    showLoading()
    axios.get(url, {
      params: params,
      // 解决get传数组问题，主要是以下五行代码
      paramsSerializer: {
        serialize: function (params) {
          return Qs.stringify(params, { arrayFormat: 'repeat' })
        }
      },
    })
