vue3学习——axios封装

安装

pnpm i axios

/src/utils/request.ts

import axios from 'axios'
import { ElMessage } from 'element-plus'
const request = axios.create({
  baseURL: import.meta.env.VITE_APP_BASE_API,
  timeout: 5000,
})
// 请求拦截器
request.interceptors.request.use((config) => {
  config.headers.token = '123'
  return config
})
//响应拦截器
request.interceptors.response.use(
  (response) => {
    return response.data
  },
  (error) => {
    //处理网络错误
    let msg
    let status = error.response.status
    switch (status) {
      case 401:
        msg = 'token过期'
        break
      case 403:
        msg = '无权访问'
        break
      case 404:
        msg = '请求地址错误'
        break
      case 500:
        msg = '服务器出现问题'
        break
      default:
        msg = '无网络'
    }
    ElMessage({
      type: 'error',
      message: msg,
    })
    return Promise.reject(error)
  },
)
export default request

使用

App.vue

import request from '@/utils/request.ts'
onMounted(() => {
  request.post('/user/login', {
    username: 'admin',
    password: '1112111',
  })
})
