1. 在main.js导入axios

2. 通过axios对象定义拦截器

import {createApp} from 'vue'
import App from './App.vue'
import Antd from 'ant-design-vue';
import 'ant-design-vue/dist/antd.css';
import axios from "axios";
import router from './router'
import store from './store'

/**
 * axios拦截器  ---request拦截器
 */
axios.interceptors.request.use(config => {
    console.log('请求参数', config)
    return config
},error => {
    console.log('请求错误', error)
    return Promise.reject(error)
})

/**
 * axios拦截器  ---response拦截器
 */
axios.interceptors.response.use(response => {
    console.log('响应参数', response)
    return response
},error => {
    console.log('响应错误', error)
    return Promise.reject(error)
})

createApp(App).use(Antd).use(store).use(router).mount('#app')
