Vue项目中API设计及拦截器使用

合理添加拦截器、明确API设计的好处：

• 统一管理接口
• 减少参数重传
• 规范前端开发
• 提升开发效率

合理设计拦截器

import axios from 'axios'
import Router from '@/router'
import { Notification } from 'element-ui'
// 获取全局baseURL
const baseUrl = window.g.baseURL
// 设置axios默认URL
axios.defaults.baseURL = baseUrl
// 对token添加过期处理
export default async (url, data) => {
  const res = await axios.post(url, data)
  // access_token过期
  if (res.data.res === 1100) {
    Notification.error({
      title: '错误',
      message: res.data.msg,
      duration: 1500
    })
    Router.push('/')
  }
  return res
}

// 一、请求拦截器
axios.interceptors.request.use(function (config) {
  // 拦截器处理（这里使用FormData传参，并简单添加token）
  const fm = new FormData()
  if (config.data) {
    // 添加access_token
    if (sessionStorage.access_token) {
      fm.append('access_token',sessionStorage.access_token)
    }
  config.data = fm
  return config
}, function (error) {
  // 对请求错误做些什么
  Notification.error({
    title: '系统错误',
    message: '服务器连接失败',
    duration: 1500
  })
  return Promise.reject(error)
})
// 二、响应拦截器
axios.interceptors.response.use(function (response) {
  return response
}, function (error) {
  // 对响应错误做点什么
  Notification.error({
    title: '系统错误',
    message: '服务器连接失败',
    duration: 1500
  })
  return Promise.reject(error)
})

统一设计管理API

import axios from './axios'

const SUPERKET= 'superket'

// 登录
const ADMIN = '/admin'
export const adminLogin = (data) => axios(SUPERKET+ ADMIN + '/login', data)
// 管理员管理
export const adminList = (data) => axios(SUPERKET+ ADMIN + '/list', data)
export const adminAdd = (data) => axios(SUPERKET+ ADMIN + '/add', data)
export const adminEdit = (data) => axios(SUPERKET+ ADMIN + '/changePassword', data)
export const adminDel = (data) => axios(SUPERKET+ ADMIN + '/del', data)

// 系统设置
const SYSTEM = '/system'
export const systemList = (data) => axios(SUPERKET+ SYSTEM + '/list', data)
export const systemEdit = (data) => axios(SUPERKET+ SYSTEM + '/edit', data)

// 人员管理
const MEMBER = '/member'
export const memberList = (data) => axios(SUPERKET+ MEMBER + '/list', data)
export const memberAdd = (data) => axios(SUPERKET+ MEMBER + '/add', data)
export const memberEdit = (data) => axios(SUPERKET+ MEMBER + '/edit', data)
export const memberDel = (data) => axios(SUPERKET+ MEMBER + '/del', data)
