Vue回炉重造之三次封装axios

在src目录下建立一个request文件夹。里面建立两个文件：

http.js
api.js

源码内容

http.js

import axios from ‘axios’ // 引入axios
import store from ‘…/store/index’ // 引入Vuex
import router from ‘…/router’ // 引入vue-router
import { Message } from ‘element-ui’ //局部引入UI框架组件
// 环境的切换
if (process.env.NODE_ENV === ‘development’) {
axios.defaults.baseURL = ‘https://xxx/’ // 开发环境
} else if (process.env.NODE_ENV === ‘debug’) {
axios.defaults.baseURL = ‘’ // 调试环境
} else if (process.env.NODE_ENV === ‘production’) {
axios.defaults.baseURL = ‘https://xxx/’ // 生产环境
}
axios.defaults.timeout = 10000;
// 请求拦截器
axios.interceptors.request.use(
config => {
if (localStorage.getItem(‘Authorization’)) {
config.headers.Authorization = Bearer + " " + localStorage.getItem(‘Authorization’); //查看是否存在token
return config;
} else if (config.isUpload) {
config.headers = { ‘Content-Type’: ‘multipart/form-data’} // 根据参数是否启用form-data方式
return config;
} else {
config.headers = { ‘Content-Type’: ‘application/json’ }
return config;
}
},
error => {
return Promise.error(error)
})

// 响应拦截器
axios.interceptors.response.use(
// 服务码是200的情况
response => {
if (response.status === 200) {
switch (response.data.code) {
// 未登录
case 3:
Message({
message: ‘未登录’,
type: ‘error’,
offset:380,
duration:1000
});
// 清除登录状态，返回首页
localStorage.removeItem(‘Authorization’)
localStorage.removeItem(‘info’)
store.commit(“changeNull”)
if (router.app._route.name != ‘home’) {
setTimeout(() => {
router.push({
path: ‘/’,
})
}, 1000)
}
break;
// 课程已添加
case 100:
Message({
message: ‘课程已添加’,
type: ‘error’,
offset:380,
duration:1000
});
break;
// token过期
case 5:
Message({
message: ‘登录过期，请重新登录’,
type: ‘error’,
offset:380,
duration:1000
});
