在工程化项目中对 axios 异步请求做一些封装可以方便使用，本文记录一种我习惯的 axios 封装及使用方法。

// service.js 创建 axios 实例，添加请求和响应拦截
const service = axios.create({
  baseURL: ''
})
service.interceptors.request.use(
  config => {
    ...
    return config
  },
  err => {
    return Promise.rject(err)
  }
)
service.interceptors.response.use(
  response => {
    return response.data
  },
  err => {
    return Promise.reject(err)
  }
)

// useAxios.js 声明不同的 Method 方法

  const { url, method, params, data } = option
  const staticParams = {} // 通用参数，如 uid 等

    url,
    method,
    params: Object.assign(params || {}, staticParams),

// 在组件中引入需要的请求方法使用
import { methodGet, methodPost } from '@/src/axios/common.js'

methodGet('api/xxx', {}).then(res => {
  console.log(res)
})

methodPost('api/xxx', {}).then(res => {
  console.log(res)
})
