vue项目中axios的封装(简单版)
代码结构:
axios-json.js 的代码:
import axios from 'axios'import storage from '@/util/storage'// import Qs from 'qs'import router from '@/router/index'import store from '@/store/index'import Element from 'element-ui'import {openPageLoading,closePageLoading} from "@/util"function getRootPath_dc() { let pathName = window.location.pathname.substring(1); let webName = pathName =='' ?'' : pathName.substring(0, pathName.indexOf('/')); if (webName =="") { return window.location.protocol +'//' + window.location.host; } else { return window.location.protocol +'//' + window.location.host +'/' + webName; }}let apiJsonpParam = null;if(process.env.NODE_ENV=='development'){ apiJsonpParam = { headers: {'Content-Type': 'application/json;charset=utf-8'}, timeout: 5000, responseType: 'json' }} else { apiJsonpParam = { headers: {'Content-Type': 'application/json;charset=utf-8'}, timeout: 5000, responseType: 'json', baseURL:getRootPath_dc() }}const apiJson = axios.create(apiJsonpParam)let serviceLoadingNum = 0let serviceLoadingTem = nullapiJson.interceptors.request.use( request => { // 打开遮罩层 if(request.loading==undefined || request.loading==true){ clearTimeout(serviceLoadingTem) openPageLoading() serviceLoadingNum ++ } if(store.state.user.token){ request.headers['access_token']=store.state.user.token; storage.local.remove('tokenid') } if(storage.local.get('tokenid')){ request.headers['tokenid']=storage.local.get('tokenid'); } if(request.method=='get'){ let url = request.url; if(request.url.indexOf('?')>-1){ request.url= url+'&randomnumber='+Math.random(); } else { request.url= url+'?randomnumber='+Math.random(); } } return request }, error=>{ return Promise.reject(error) })apiJson.interceptors.response.use( response => { // 关闭遮罩层 if(response.config.loading==undefined || response.config.loading==true){ serviceLoadingNum -- if(serviceLoadingNum==0){ serviceLoadingTem = setTimeout(()=>{ closePageLoading() },10) } } // 系统内接口业务报错统一处理 if (!response.data.success) { // console.log(response.data,"response.data"); let message = response.data.message || response.data.msg || response.msg; if(response.data.code){ handleError(response.data.code, message); return Promise.reject(response.data) } } else { return Promise.resolve(response.data.result); } }, error => { if(error && error.response){ if(error.response.config.loading==undefined || error.response.config.loading==true){ serviceLoadingNum -- if(serviceLoadingNum==0){ serviceLoadingTem = setTimeout(()=>{ closePageLoading() },10) } } handleError(error.response.status) return Promise.reject(error.response) } return Promise.reject(error) })export function handleError(errorCode,errormsg=''){ switch (errorCode) { // 401: 未登录 case 401: Element.Message.error("登录失效,请重新登录!") break; // 404请求不存在 case 404: Element.Message.error("请求接口不存在!"); break; case 400: Element.Message.error('400') break; case 500: let errMsg=errormsg||"服务正在维护中,请稍后..."; // Element.Message(errMsg); Element.Message({ showClose: true, message: errMsg, type: 'error' }); break; // 其他错误,直接抛出错误提示 default: Element.Message({ showClose: true, message:'服务发生异常,请稍后重试!', type: 'error' }) }}export default
针对 axios-json.js 中的 import {openPageLoading,closePageLoading} from "@/util" ,其中 util 文件夹下 index.js 里面的这两个方法为:
import Element from 'element-ui'// 打开遮罩层export function openPageLoading(){ Element.Loading.service({ fullscreen: true, lock: true, text: '正在加载中,请稍候 ...', spinner: 'el-icon-loading', // spinner: 'ri-loader-2-line', background: 'rgba(255, 255, 255, 0.4)' })}// 关闭遮罩层export function closePageLoading(){ Element.Loading.service().close();}
main.js 中的相关代码:
import apiJson, {handleError} from './api/axios-json'Vue.prototype.$apiJson = apiJsonVue.prototype.$handleError=handleError; //此方法可能没用,做个参考
用法:
async getFuncExample(){ let url = "xxx"; let params={id:"xxx"} let res; await res = apiJson.get(url, { params });}async postFuncExample(){ let url = "xxx"; let params={id:"xxx"} let res; await res = apiJson.get(url, params);}
