[JavaScript知识库]VUE封装request.js拦截过滤器

1、创建request.js

import axios from 'axios'
import { MessageBox, Message } from 'element-ui'
import store from '@/store'
import { getToken } from '@/utils/auth'

const service = axios.create({
  baseURL: process.env.VUE_APP_BASE_API,
  timeout: 5000 
})

// request interceptor
service.interceptors.request.use(
  config => {
    if (store.getters.token) {
      config.headers['token'] = getToken()
    }
    return config
  },
  error => {
    return Promise.reject(error)
  }
)

// response interceptor
service.interceptors.response.use(
  response => {
    const res = response.data  
    if (res.code != 200) {
      console.log(res)
      Message({
        message: res.message || 'Error',
        type: 'error',
        duration: 5 * 1000
      })
      /*if (res.code === 50008 || res.code === 50012 || res.code === 50014) {
        MessageBox.confirm('You have been logged out, you can cancel to stay on this page, or log in again', 'Confirm logout', {
          confirmButtonText: 'Re-Login',
          cancelButtonText: 'Cancel',
          type: 'warning'
        }).then(() => {
          store.dispatch('user/resetToken').then(() => {
            location.reload()
          })
        })
      }*/
      return Promise.reject(new Error(res.message || 'Error'))
    } else {
      return res
    }
  },
  error => {
    Message({
      message: error.message,
      type: 'error',
      duration: 5 * 1000
    })
    return Promise.reject(error)
  }
)

export default service

2、在api文件下创建js对接口进行二次封装

import request from '@/utils/request'//导入上面的requset.js 

export function getAllMessageInfo(pages) {
    return request({
        url: '/messageInfo/getAllMessageInfo',
        method: 'post',
        data: pages
    })
}

3、在组件vue文件上对于自己写的方法进行调用

<script>
 import {getAllMessageInfo} from "@/api/messageInfo/messageInfo"//导入方法
  okgetAllMessageInfo() {
      const pages={}
      pages.current=this.current
      pages.size=this.size
      getAllMessageInfo(pages).then(response=>{
         console.log(response)//这里可以做自己想做的事情
      })
  },
 </script>
