vue(32) : win10创建vue2基础前端框架

vue2
element-ui
axios

1.创建vue2项目

开发工具为HBuilderX 3.7.3

1.1.新建项目

1.2.普通项目-vue项目(2.6.10)

等待创建项目

2.安装element-ui组件

2.1右键左下角开始图标

2.2.cd进入项目目录,执行安装element-ui

npm i element-ui -S

2.3.main.js引入配置

import {Pagination,Dialog,Autocomplete,Dropdown,DropdownMenu,DropdownItem,Menu,Submenu,MenuItem,MenuItemGroup,Input,InputNumber,Radio,RadioGroup,RadioButton,Checkbox,CheckboxButton,CheckboxGroup,Switch,Select,Option,OptionGroup,Button,ButtonGroup,Table,TableColumn,DatePicker,TimeSelect,TimePicker,Popover,Tooltip,Breadcrumb,BreadcrumbItem,Form,FormItem,Tabs,TabPane,Tag,Tree,Alert,Slider,Icon,Row,Col,Upload,Progress,Spinner,Badge,Card,Rate,Steps,Step,Carousel,CarouselItem,Collapse,CollapseItem,Cascader,ColorPicker,Transfer,Container,Header,Aside,Main,Footer,Timeline,TimelineItem,Link,Divider,Image,Calendar,Backtop,PageHeader,CascaderPanel,Loading,MessageBox,Message,Notification

Vue.prototype.$confirm = MessageBox.confirm;
Vue.prototype.$prompt = MessageBox.prompt;
Vue.prototype.$notify = Notification;
Vue.prototype.$message = Message;
import 'element-ui/lib/theme-chalk/index.css';

3.安装axios

3.1.npm安装axios

npm install --save axios

3.2.项目根目录创建[vue.config.js]文件, 内容如下

'use strict'
const path = require('path')function resolve(dir) {return path.join(__dirname, dir)
}const port = process.env.port || process.env.npm_config_port || 9527 // dev port
const name =  '测试' // page title// All configuration item explanations can be find in https://cli.vuejs.org/config/
module.exports = {/*** You will need to set publicPath if you plan to deploy your site under a sub path,* for example GitHub Pages. If you plan to deploy your site to https://foo.github.io/bar/,* then publicPath should be set to "/bar/".* In most cases please use '/' !!!* Detail: https://cli.vuejs.org/config/#publicpath*/publicPath: '/',outputDir: 'dist',assetsDir: 'static',lintOnSave: process.env.NODE_ENV === 'development',productionSourceMap: false,devServer: {port: port,open: true,overlay: {warnings: false,errors: true},proxy: {// 代理test开头的uri'/test': {target: 'http://192.168.1.1:8080', // 后端地址// target: 'localhost:8080/manage', // 原始地址changeOrigin: true, // 开启代理，在本地创建一个虚拟服务端pathRewrite: {'^/test': '/test'}}}//before: require('./mock/mock-server.js')},configureWebpack: {// provide the app's title in webpack's name field, so that// it can be accessed in index.html to inject the correct title.name: name,resolve: {alias: {'@': resolve('src')}}},chainWebpack(config) {// it can improve the speed of the first screen, it is recommended to turn on preload// it can improve the speed of the first screen, it is recommended to turn on preloadconfig.plugin('preload').tap(() => [{rel: 'preload',// to ignore runtime.js// https://github.com/vuejs/vue-cli/blob/dev/packages/@vue/cli-service/lib/config/app.js#L171fileBlacklist: [/\.map$/, /hot-update\.js$/, /runtime\..*\.js$/],include: 'initial'}])// when there are many pages, it will cause too many meaningless requestsconfig.plugins.delete('prefetch')// set svg-sprite-loaderconfig.module.rule('svg').exclude.add(resolve('src/icons')).end()config.module.rule('icons').test(/\.svg$/).include.add(resolve('src/icons')).end().use('svg-sprite-loader').loader('svg-sprite-loader').options({symbolId: 'icon-[name]'}).end()config.when(process.env.NODE_ENV !== 'development',config => {config.plugin('ScriptExtHtmlWebpackPlugin').after('html').use('script-ext-html-webpack-plugin', [{// `runtime` must same as runtimeChunk name. default is `runtime`inline: /runtime\..*\.js$/}]).end()config.optimization.splitChunks({chunks: 'all',cacheGroups: {libs: {name: 'chunk-libs',test: /[\\/]node_modules[\\/]/,priority: 10,chunks: 'initial' // only package third parties that are initially dependent},elementUI: {name: 'chunk-elementUI', // split elementUI into a single packagepriority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or apptest: /[\\/]node_modules[\\/]_?element-ui(.*)/ // in order to adapt to cnpm},commons: {name: 'chunk-commons',test: resolve('src/components'), // can customize your rulesminChunks: 3, //  minimum common numberpriority: 5,reuseExistingChunk: true}}})// https:// webpack.js.org/configuration/optimization/#optimizationruntimechunkconfig.optimization.runtimeChunk('single')})}
}

代理后端配置如下, 三个test改成相同的uri前缀即可, uri该签注会代理到后端

proxy: {
// 代理test开头的uri
'/test': {
target: 'http://192.168.1.1:8080', // 后端地址
changeOrigin: true, // 开启代理，在本地创建一个虚拟服务端
pathRewrite: {
'^/test': '/test'
}
}
}

3.3.src下创建util目录, util文件夹下创建request.js, 内容如下

const res = response.data

这个需要根据后端接口格式修改

/*引入axios*/
import axios from 'axios'
import { MessageBox, Message } from 'element-ui'const request = axios.create({baseURL: '', // 基础路径,将统一的部分全部封装withCredentials: true // 表示请求可以携带cookie
})axios.defaults.headers['Content-Type'] = 'application/x-www-form-urlencoded'// response interceptor
request.interceptors.response.use(/*** If you want to get http information such as headers or status* Please return  response => response*//*** Determine the request status by custom code* Here is just an example* You can also judge the status by HTTP Status Code*/response => {const res = response.data// if the custom code is not 20000, it is judged as an error.if (res.code !== '0') {Message({message: res.message || 'Error',type: 'error',duration: 3 * 1000})// return Promise.reject(new Error(res.message || 'Error'))return null} else {return res}},error => {console.log('err' + error) // for debugMessage({message: error.message,type: 'error',duration: 5 * 1000})return Promise.reject(error)}
)//前端采用export.default，在写后端代码时用module.export
export default request

4.创建测试调用http

4.1.src下创建api目录, api下创建test.js, 内容如下

import request from '@/util/request'export function add(data) {return request({url: '/my-boke',headers: { 'Content-Type': 'application/json' },method: 'post',data})
}export function update(data) {return request({url: '/my-boke',headers: { 'Content-Type': 'application/json' },method: 'put',data})
}export function del(data) {return request({url: '/my-boke',method: 'delete',params: data})
}export function env() {return request({url: '/fsa/env',method: 'get'})
}

4.2. vue.js调用http

<template></template><script>import {add,update,del,env} from '@/api/fsa'export default {name: 'app',data() {return {}},created() {this.t1()},methods: {t1() {env().then(response => {console.log(response)})}}}
</script><style>#app {font-family: 'Avenir', Helvetica, Arial, sans-serif;-webkit-font-smoothing: antialiased;-moz-osx-font-smoothing: grayscale;text-align: center;color: #2c3e50;margin-top: 60px;}
</style>
