1. 安装vue项目 npm init webpack project
2 安装iview npm i iview --save (这里是结合iview框架使用的 可根据自己的需求安装 当然也可以不安装)
3 在src目录下建一个utils文件夹 里面需要放5个js 都是封装好的js文件 功能不仅仅局限于加密 可以研究一下 你会学到很多东西
1.api.js
/** * 为vue实例添加http方法 * Vue.use(http) */ import http from './http' export default { /** * install钩子 * @param {Vue} Vue Vue */ install (Vue) { Vue.prototype.http = http } }
2. filters.js
// 公共使用的filters import Vue from 'vue'; import {getTime, getPrdType} from '../utils/time'; // 区分支付方式的filter Vue.filter('paywayType', function (value) { return value; }); // 时间 Vue.filter('newdate', function (value) { return getTime(value); }); // 时间-分钟 Vue.filter('minute', function (str, n) { const num = parseInt(n); return str.split(' ')[num]; }); // 分割以:连接多个参数的string Vue.filter('valStr', function (str, n) { const num = parseInt(n); return str.split(':')[num]; }); // 根据提供时间计算倒计时 Vue.filter('countDown', function (str) { const dateStr = new Date(str).getTime(); const timeNow = new Date().getTime(); const countDown = dateStr - timeNow; const countDownDay = Math.floor((dateStr - timeNow) / 86400000);// 计算剩余天数 const countDownHour = Math.floor((dateStr - timeNow) / 3600000 % 24);// 计算剩余小时 const countDownMin = Math.floor((dateStr - timeNow) / 60000 % 60);// 计算剩余分钟 // const countDownSec = Math.floor((dateStr - timeNow) / 1000 % 60);// 计算剩余秒 if (countDown <= 0) { return '- - - -'; } else { return countDownDay + '天' + countDownHour + '小时' + countDownMin + '分钟'; } }); // 取绝对值 Vue.filter('numberFn', function (numberStr) { return Math.abs(numberStr); }); // 处理图片地址的filter Vue.filter('imgSrc', function (src) { const env = getPrdType(); switch (env) { case 'pre': return `https://preres.bldz.com/${src}`; case 'pro': return `https://res.bldz.com/${src}`; case 'test': default: return `https://testimg.bldz.com/${src}`; } }); // 直接转化剩余时间 Vue.filter('dateShow', function (dateStr) { const countDownDay = Math.floor(dateStr / 86400);// 计算剩余天数 const countDownHour = Math.floor(dateStr / 3600 % 24);// 计算剩余小时 const countDownMin = Math.floor(dateStr / 60 % 60);// 计算剩余分钟 // const countDownSec = Math.floor((dateStr - timeNow) / 1000 % 60);// 计算剩余秒 if (dateStr <= 0) { return '- - - -'; } else if (countDownDay <= 0 && countDownHour <= 0) { return countDownMin + '分钟'; } else if (countDownDay <= 0) { return countDownHour + '小时' + countDownMin + '分钟'; } else { return countDownDay + '天' + countDownHour + '小时' + countDownMin + '分钟'; } }); // 处理图片 Vue.filter('imgLazy', function (src) { return { src, error: '../static/images/load-failure.png', loading: '../static/images/default-picture.png' }; }); Vue.filter('imgHandler', function (src) { return src.replace(/,jpg/g, '.jpg'); });
3.http.js
import axios from 'axios' import utils from '../utils/utils' import {Modal} from 'iview' // import qs from 'qs'; axios.defaults.timeout = 1000*60 axios.defaults.baseURL = '' const defaultHeaders = { Accept: 'application/json, text/plain, */*; charset=utf-8', 'Content-Type': 'application/json; charset=utf-8', Pragma: 'no-cache', 'Cache-Control': 'no-cache' } // 设置默认头 Object.assign(axios.defaults.headers.common, defaultHeaders) const methods = ['get', 'post', 'put', 'delete'] const http = {} methods.forEach(method => { http[method] = axios[method].bind(axios) }) export default http export const addRequestInterceptor = axios.interceptors.request.use.bind(axios.interceptors.request) // request前自动添加api配置 addRequestInterceptor( (config) => { if (utils.getlocal('token')) { // 判断是否存在token,如果存在的话,则每个http header都加上token config.headers.Authentication = utils.getlocal('token') } // config.url = `/api${config.url}` return config }, (error) => { return Promise.reject(error) } ) export const addResponseInterceptor = axios.interceptors.response.use.bind(axios.interceptors.response) addResponseInterceptor( (response) => { // 在这里统一前置处理请求响应 if (Number(response.status) === 200) { // 全局notify有问题,还是自己处理吧 // return Promise.reject(response.data) // window.location.href = './' // this.$router.push({ path: './' }) } return Promise.resolve(response.data) }, (error) => { if (error.response) { const title = '温馨提示'; const content = '<p>登录过期请重新登录</p>' switch (error.response.status) { case 401: // 返回 401 跳转到登录页面 Modal.error({ title: title, content: content, onOk: () => { localStorage.removeItem("lefthidden") localStorage.removeItem("leftlist") localStorage.removeItem("token") localStorage.removeItem("userInfo") localStorage.removeItem("headace") localStorage.removeItem("sideleft") utils.delCookie("user"); window.location.href = './' } }) break } } return Promise.reject(error || '出错了') } )
4. time.js
// 常用的工具api const test = 'test'; const pre = 'pre'; const pro = 'pro'; export function judeType (param, typeString) { if (Object.prototype.toString.call(param) === typeString) return true; return false; }; export function isPrd () { return process.env.NODE_ENV === 'production'; }; export function getPrdType () { return ENV; }; export const ls = { put (key, value) { if (!key || !value) return; window.localStorage[key] = JSON.stringify(value); }, get (key) { if (!key) return null; const tem = window.localStorage[key]; if (!tem) return null; return JSON.parse(tem); }, // 设置cookie setCookie (key, value, time) { if (time) { let date = new Date(); date.setDate(date.getDate() + time); document.cookie = key + '=' + value + ';expires=' + date.toGMTString() + ';path=/'; } else { document.cookie = key + '=' + value + ';path=/'; } }, // 获取cookie getCookie (key) { let array = document.cookie.split('; '); array.map(val => { let [valKey, value] = val.split('='); if (valKey === key) { return decodeURI(value); } }); return ''; } }; /** * 判断元素有没有该class * @param {*} el * @param {*} className */ export function hasClass (el, className) { let reg = new RegExp('(^|\\s)' + className + '(\\s|$)'); return reg.test(el.className); } /** * 为元素添加class * @param {*} el * @param {*} className */ export function addClass (el, className) { if (hasClass(el, className)) return; let newClass = el.className.spilt(' '); newClass.push(className); el.className = newClass.join(' '); } export function removeClass (el, className) { if (!hasClass(el, className)) return; let reg = new RegExp('(^|\\s)' + className + '(\\s|$)', 'g'); el.className = el.className.replace(reg, ' '); } /** * 将数据存储在标签里 * @param {*} el * @param {*} name * @param {*} val */ export function getData (el, name, val) { let prefix = 'data-'; if (val) { return el.setAttribute(prefix + name, val); } return el.getAttribute(prefix + name); } export function isIphone () { return window.navigator.appVersion.match(/iphone/gi); } /** * 计算元素和视窗的位置关系 * @param {*} el */ export function getRect (el) { if (el instanceof window.SVGElement) { let rect = el.getBoundingClientRect(); return { top: rect.top, left: rect.left, width: rect.width, height: rect.height }; } else { return { top: el.offsetTop, left: el.offsetLeft, width: el.offsetWidth, height: el.offsetHeight }; } } /** * 获取不确定数据的方法api * @param {Array} p 参数数组 * @param {Object} o 对象 */ export function getIn (p, o) { return p.reduce(function (xs, x) { return (xs && xs[x]) ? xs[x] : null; }, o); } /** * 时间戳改为年月日格式时间 * @param {*} p 时间戳 */ export function getTime (p) { let myDate = new Date(p); let year = myDate.getFullYear(); let month = myDate.getMonth() + 1; let date = myDate.getDate(); if (month >= 10) { month = '' + month; } else { month = '0' + month; } if (date >= 10) { date = '' + date; } else { date = '0' + date; } return year + '-' + month + '-' + date; } export function debounce (method, delay) { let timer = null; return function () { let context = this; let args = arguments; clearTimeout(timer); timer = setTimeout(function () { method.apply(context, args); }, delay); }; }
5 utils.js
// 获取cookie、 export function getCookie (name) { if (document.cookie.length > 0){ let c_start = document.cookie.indexOf(name + '=') if (c_start != -1) { c_start = c_start + name.length + 1 let c_end = document.cookie.indexOf(';', c_start) if (c_end == -1) c_end = document.cookie.length return unescape(document.cookie.substring(c_start, c_end)) } } return '' } // 设置cookie,增加到vue实例方便全局调用 export function setCookie (cname, value, expiredays) { let exdate = new Date() exdate.setDate(exdate.getDate() + expiredays) document.cookie = cname + '=' + escape(value) + ((expiredays == null) ? '' : ';expires=' + exdate.toGMTString()) } // 删除cookie export function delCookie (name) { let exp = new Date() exp.setTime(exp.getTime() - 1) let cval = getCookie(name) if (cval != null) { document.cookie = name + '=' + cval + ';expires=' + exp.toGMTString() } } // 设置localstorage export function putlocal (key, value) { if (!key || !value) return window.localStorage[key] = JSON.stringify(value) } // 获取localstorage export function getlocal (key) { if (!key) return null const tem = window.localStorage[key] if (!tem) return null return JSON.parse(tem) } /** * use_iframe_download function - 通过 iframe 下载文件 * * @param {String} download_path 需下载文件的链接 * @return {Void} */ export const use_iframe_download = download_path => { const $iframe = document.createElement('iframe') $iframe.style.height = '0px' $iframe.style.width = '0px' document.body.appendChild($iframe) $iframe.setAttribute('src', download_path) setTimeout(function () { $iframe.remove() }, 20000) } function requestTimeout (xhr) { const timer = setTimeout(() => { timer && clearTimeout(timer) xhr.abort() }, 5000) return timer } // 导出 export function exporttable (httpUrl,token, formData, callback) { let i = formData.entries(); let param = "?Authentication="+token; do{ var v = i.next(); if(!v.done){ param+="&"+v.value[0]+"="+v.value[1]; } }while(!v.done); // console.log(param); window.open(httpUrl+param) // var xhr = new XMLHttpRequest() // if (xhr.withCredentials === undefined){ // return false // }; // xhr.open("post", httpUrl) // // xhr.timeout=5000 // xhr.setRequestHeader("Authentication", token) // xhr.responseType = "blob" // let timer = requestTimeout(xhr) // xhr.onreadystatechange = function () { // timer && clearTimeout(timer) // if (xhr.readyState !== 4) { // timer = requestTimeout(xhr) // return // } // if (this.status === 200) { // var blob = this.response // var contentType = this.getResponseHeader('content-type') // var fileName = contentType.split(";")[1].split("=")[1] // fileName = decodeURI(fileName) // let aTag = document.createElement('a') // // 下载的文件名 // aTag.download = fileName // aTag.href = URL.createObjectURL(blob) // aTag.click() // URL.revokeObjectURL(blob) callback && callback(true) // } else { // callback && callback(false) // } // } // xhr.send(formData); } // 获取当前时间 export function getNowFormatDate() { var date = new Date(); var seperator1 = "-"; var seperator2 = ":"; var month = date.getMonth() + 1; var strDate = date.getDate(); if (month >= 1 && month <= 9) { month = "0" + month; } if (strDate >= 0 && strDate <= 9) { strDate = "0" + strDate; } var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate + " " + date.getHours() + seperator2 + date.getMinutes() + seperator2 + date.getSeconds(); return currentdate; } // 时间格式化 export function formatDate(date, fmt) { if (/(y+)/.test(fmt)) { fmt = fmt.replace(RegExp.$1, (date.getFullYear() + '').substr(4 - RegExp.$1.length)); } let o = { 'M+': date.getMonth() + 1, 'd+': date.getDate(), 'h+': date.getHours(), 'm+': date.getMinutes(), 's+': date.getSeconds() }; for (let k in o) { if (new RegExp(`(${k})`).test(fmt)) { let str = o[k] + ''; fmt = fmt.replace(RegExp.$1, (RegExp.$1.length === 1) ? str : padLeftZero(str)); } } return fmt; }; function padLeftZero(str) { return ('00' + str).substr(str.length); } export default { getCookie, setCookie, delCookie, putlocal, getlocal, exporttable, getNowFormatDate, formatDate }
4.配置main.js
import Vue from 'vue' import App from './App' import router from './router' import VueRouter from 'vue-router'; import iView from 'iview'; import 'iview/dist/styles/iview.css' import http from './utils/http' import Api from './utils/api' import utils from './utils/utils' import './utils/filters' Vue.config.productionTip = false Vue.use(VueRouter); Vue.use(iView); Vue.use(http) Vue.use(Api) Vue.use(utils) /* eslint-disable no-new */ global.BASE_URL = process.env.API_HOST new Vue({ el: '#app', router, components: { App }, template: '<App/>' })
5.找到config文件夹下的dev.env.js
module.exports = merge(prodEnv, { NODE_ENV: '"development"', API_HOST: '"开发环境接口地址"' })
6.页面中具体使用方法
<template> <div class="hello"> <Select v-model="model8" clearable style="width:200px"> <Option v-for="item in cityList" :value="item.productCode" :key="item.productCode">{{item.productName }}</Option> </Select> </div> </template> <script> export default { name: 'HelloWorld', data () { return { cityList:[], model8:"code" } }, mounted(){ this.http .post(BASE_URL + "请求路径",{}) .then(data => { if (data.code == "success") { this.cityList = data.data; this.cityList.splice(0,0,{ productCode: "code", productName: "所有产品" }) } }) .catch(err => { console.log(err); }); } } </script> <style scoped> </style>
