目录
一.环境准备
1.下载nodejs v16.x
下载地址:Node.js — Download Node.js®
2.设置淘宝镜像源
# 设置淘宝镜像
npm config set registry https://registry.npmmirror.com/
# 查看
vue config
Resolved path: C:\Users\oslee\.vuerc
{
"useTaobaoRegistry": false
}
3.安装脚手架
vue2.x语法参考官网(后续更新3.x教程):介绍 — Vue.js
npm install -g @vue/cli
# 可以用这个命令来检查其版本是否正确
vue --version
可能发生的问题
vue : 无法加载文件 C:\Users\XXX\AppData\Roaming\npm\vue.ps1,因为在此系统上禁止运行脚本
解决: 搜索powershell,以管理员的身份运行 输入下面的指令:set-ExecutionPolicy RemoteSigned 选择y
二.Vue项目
1.创建一个项目
vue create vue
# 启动
cd vue
npm run serve
2.项目修改
# 修改vue/vue.config.js
const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({
devServer: {
port: 7000
},
chainWebpack: config => {
config.plugin('html')
.tap(args=> {
args[0].title = "oslee好帅"
return args
})
}
})
# vue/src/App.vue
<template>
<div id="app">
<router-view/>
</div>
</template>
# vue/src/views/HomeView.vue
<template>
<div>
主页
</div>
</template>
<script>
export default {
name: 'HomeView',
}
</script>
# vue/src/router/index.js
import Vue from 'vue'
import VueRouter from 'vue-router'
Vue.use(VueRouter)
const routes = [
{
path: '/',
name: 'home',
component: () => import(/* webpackChunkName: "about" */ '../views/HomeView.vue')
}
]
const router = new VueRouter({
mode: 'history',
base: process.env.BASE_URL,
routes
})
export default router
# vue/src/assets/css/global.css
* {
box-sizing: border-box;
}
body{
color: #333;
font-size: 14px;
margin: 0;
padding: 0;
}
三.Vue使用Element-UI
1.安装Element-UI
Element-UI网址:Element - The world's most popular Vue UI framework
# 设置淘宝镜像
npm config set registry https://registry.npmmirror.com/
# 查看npm镜像
npm config get
# 也可安装nrm管理npm镜像
npm install nrm -g
# 切换镜像并查看
nrm ls
nrm use taobao
nrm current
# 安装element-ui
npm i element-ui -S
2.引入Element-UI
在main.js中写入以下内容:
import Vue from 'vue'
import App from './App.vue'
import router from './router'
import '@/assets/css/global.css'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI, {size:'small'});
new Vue({
router,
render: h => h(App)
}).$mount('#app')
四.Vue封装前后端数据交互工具
1.安装 axios
npm i axios -S
2.封装request.js
import axios from 'axios'
// 创建可一个新的axios对象
const request = axios.create({
baseURL: 'http://localhost:9090', // 后端的接口地址 ip:port
timeout: 30000
})
// request 拦截器
// 可以自请求发送前对请求做一些处理
// 比如统一加token,对请求参数统一加密
request.interceptors.request.use(config => {
config.headers['Content-Type'] = 'application/json;charset=utf-8';
// let user = localStorage.getItem("user") ? JSON.parse(localStorage.getItem("user")) : null
// config.headers['token'] = 'token' // 设置请求头
return config
}, error => {
console.error('request error: ' + error) // for debug
return Promise.reject(error)
});
// response 拦截器
// 可以在接口响应后统一处理结果
request.interceptors.response.use(
response => {
let res = response.data;
// 兼容服务端返回的字符串数据
if (typeof res === 'string') {
res = res ? JSON.parse(res) : res
}
return res;
},
error => {
console.error('response error: ' + error) // for debug
return Promise.reject(error)
}
)
export default request
五.使用particles动态粒子效果,优化登录页
1.引入插件
npm install vue-particles --save-dev
// main.js
import Vue from 'vue'
import App from './App.vue'
import router from './router'
import '@/assets/css/global.css'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import VueParticles from 'vue-particles'
Vue.use(VueParticles)
Vue.use(ElementUI, {size:'small'});
new Vue({
router,
render: h => h(App)
}).$mount('#app')
