Vue前端项目axios拦截实战使用(interceptors.request,interceptors.response)和Vue.use()

在main.js入口文件里：

// 安装VueAxios,让全局Vue含有this.$HTTP请求方法
import { VueAxios } from './utils/request.js'
Vue.use(VueAxios)

request.js文件：

• axios.interceptors.request.use(config=>{},err=>{})
• service.interceptors.response.use(response=>{}, err=>{})

import Vue from 'vue'
import axios from 'axios'
import store from '@/store'
import notification from 'ant-design-vue/es/notification'

import { ACCESS_TOKEN } from '@/store/mutation-types'

const baseURL = 'http://192.168.0.192:8080/api'
// 创建 axios 实例
const service = axios.create({
  baseURL: baseURL, // api base_url
  timeout: 6000 // 请求超时时间
})

const err = (error) => {
  if (error.response) {
    const data = error.response.data
    const token = Vue.ls.get(ACCESS_TOKEN)
    if (error.response.status === 403) {
      notification.error({
        message: 'Forbidden',
        description: data.message
      })
    }
    if (error.response.status === 401 && !(data.result && data.result.isLogin)) {
      notification.error({
        message: 'Unauthorized',
        description: 'Authorization verification failed'
      })
      if (token) {
        store.dispatch('Logout').then(() => {
          setTimeout(() => {
            window.location.reload()
          }, 1500)
        })
      }
    }
  }
  return Promise.reject(error)
}

// request interceptor
service.interceptors.request.use(config => {
  const token = Vue.ls.get(ACCESS_TOKEN)
  if (token) {
    config.headers['Access-Token'] = token // 让每个请求携带自定义 token 请根据实际情况自行修改
  }
  return config
}, err)

// response interceptor
service.interceptors.response.use((response) => {
  return response.data
}, err)

const installer = {
  vm: {},
  install: (Vue) => {
    if (this.installed) {
      return
    }
    Object.defineProperties(Vue.prototype, {
      $http: {
        get: function get () {
          return service
        }
      }
    })
    this.installed = true
  }
}

export {
  installer as VueAxios
}
