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) {

});

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: '
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"'
})
