本篇文章给大家带来的内容是关于vue中axios请求的封装的介绍(代码),有一定的参考价值,有需要的朋友可以参考一下,希望对你有所帮助。
1、发送请求模块目录
2、/api/url中存放的是每个模块的URL
// 商品模块 product.js const product = { sku: { list: '/product/product/speclist', options: '/product/product/options' } } export default product // 公用请求模块 common.js const common = { region: { provinces: '/region/region/list', cities: '/region/region/list' }, upload: { image: '/product/product/upload' } } export default common
发送请求的时候只需要指定key(sku/list),如:this.$ajax('sku/list', param);假定axios设置的baseURL是http://prod.storm.com/api/,那么最终的请求地址:http://prod.storm.com/api/pro...
使用webpack提供的require.context将src/api/url下后缀为js的所有文件引入,并整理出一个对象。
let urls = {} const req = require.context('./url', false, /\.js$/) const requireAll = requireContext => requireContext.keys().map(i => { let url = requireContext(i) Object.assign(urls, url.default) }) requireAll(req) export default urls
整合common.js & product.js,最终得到的对象如下:
urls = { sku: { list: '/product/product/speclist', options: '/product/product/options' }, region: { provinces: '/region/region/list', cities: '/region/region/list' }, upload: { image: '/product/product/upload' } }
import axios from 'axios' import qs from 'qs' import jsd from 'js-file-download' import store from '@/store' import urlObj from './requireURLs' import { Message, MessageBox } from 'element-ui' import { getToken } from '@/utils/auth' const service = axios.create({ baseURL: `${process.env.BASE_API}/api/`, // 不同环境(dev/prod/test)使用不同的baseURL timeout: 5000 }) service.interceptors.request.use( config => { // 上传文件时,config.data的数据类型是FormData, // qs.stringify(FormData)的结果是空字符串,导致报出上传文件为空的错误 if (config.method === 'post' && config.data.constructor !== FormData) { config.data = qs.stringify(config.data) } if (store.getters.token) { config.headers.common['Auth-Token'] = getToken() // Auth-Token 登录过期后,重新登录不传token if (!config.headers.common['Auth-Token']) { delete config.headers.common['Auth-Token'] } } return config }, error => { Promise.reject(error) } ) service.interceptors.response.use( response => { const res = response.data if (response.headers['content-type'].indexOf('application/vnd.ms-excel') !== -1) { let fileName = response.headers['content-disposition'].split('=')[1] jsd(res, fileName) return } if (res.code === 0) { // 和后台约定code:0代表请求成功 return res } else { if (res.code === 18500) { // 和后台约定code:18500代表token未过期,但是被更新了 handleLogin('您已被登出,请重新登录') } else if (res.code === 18501) { // 和后台约定code:18500代表token过期 handleLogin('登录已失效,请重新登录') } else { // 统一处理接口的报错信息,如果需要具体到页面去处理,可以和后台另外约定一个code Message({ message: res.msg, type: 'error', duration: 3 * 1000 }) } return Promise.reject(res) } }, error => { console.log('err ' + error) let data = error.response.data Message({ message: data.msg, type: 'error', duration: 3 * 1000 }) return Promise.reject(data) } ) const handleLogin = title => { MessageBox.confirm(title, '提示', { confirmButtonText: '重新登录', showCancelButton: false, showClose: false, type: 'warning' }).then(() => { store.dispatch('FedLogout').then(() => { location.reload() }) }) } const ajax = (path, data = {}, options = {}) => { let url = path.indexOf('http') === -1 ? path.split('/').reduce((o, k) => { return o[k] }, urlObj) : path let method = options.method || 'post' let params = { url, method } if (options.method === 'get') { Object.assign(params, { params: data }, options) } else { Object.assign(params, { data }, options) } return service(params) } export default ajax
// ajaxPlugin.js import ajax from '@/api/ajax' let ajaxPlugin = {} ajaxPlugin.install = Vue => { Vue.prototype.$ajax = ajax } export default ajaxPlugin // main.js import ajaxPlugin from '@/plugins/ajaxPlugin' Vue.use(ajaxPlugin)
this.$ajax('sku/list').then(res => {})
