vue+elementUI项目搭建

安装node

基于node之npm环境下操作vue，所以先部署node

wget https://npm.taobao.org/mirrors/node/latest-v13.x/node-v13.8.0-linux-x64.tar.gz
mkdir /usr/local/node 
tar -zxf node-v13.8.0-linux-x64.tar.gz  -C /usr/local/node/
ln -s /usr/local/node/node-v13.8.0-linux-x64/bin/npm  /usr/local/bin/npm
ln -s /usr/local/node/node-v13.8.0-linux-x64/bin/node  /usr/local/bin/node
npm -v

安装git

• 部署vue手脚架要用到git

wget http://mirror.centos.org/centos/7/extras/x86_64/Packages/epel-release-7-11.noarch.rpm
yum install -y epel-release-7-11.noarch.rpm 
yum install git -y

创建 vue 项目

• 安装全局vue-cli脚手架

npm install -g vue-cli
npm install --global webpack-cli
npm install --global webpack

ln -s /usr/local/node/node-v13.8.0-linux-x64/bin/webpack /usr/bin/webpack
ln -s /usr/local/node/node-v13.8.0-linux-x64/bin/vue  /usr/bin/vue
ln -s /usr/local/node/node-v13.8.0-linux-x64/bin/vue-init /usr/bin/vue-init
ln -s /usr/local/node/node-v13.8.0-linux-x64/bin/vue-list /usr/bin/vue-list

vue -V

# 创建项目 vuedemo
vue init webpack vuedemo
# 一路回车即可

运行项目

cd vuedemo
npm run dev

• 成功执行以上命令后访问 http://localhost:8080/
  

引入element

# 在vuedemo项目的根目录下执行
 npm i element-ui -S

• 引入 element, 在 src/main.js 中，编辑，添加如下代码

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'

import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'


Vue.config.productionTip = false

/* eslint-disable no-new */
Vue.use(ElementUI)
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})
~                                                                                                                            
~      

• 修改 src/components/HelloWorld.vue 文件，随便添加一个element组件

<template>
  <el-row>
  <el-button>默认按钮</el-button>
  <el-button type="primary">主要按钮</el-button>
  <el-button type="success">成功按钮</el-button>
  <el-button type="info">信息按钮</el-button>
  <el-button type="warning">警告按钮</el-button>
  <el-button type="danger">危险按钮</el-button>
  </el-row>
</template>

<script>
export default {
  name: 'HelloWorld',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  }
}
</script>

• 刷新页面，查看组件已成功导入
  

请求处理（axios）

还是用npm安装，安装命令 npm install axios （注意，一定是要在项目文件夹下）

• npm 安装

 npm install axios 

• 入口文件引入

# src/main.js 

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'

import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'

import axios from 'axios'
Vue.prototype.$http = axios

Vue.config.productionTip = false

/* eslint-disable no-new */
Vue.use(ElementUI)
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})
~                   

• 设置请求地址，跨域

# config/index.js 

'use strict'
// Template version: 1.3.1
// see http://vuejs-templates.github.io/webpack for documentation.

const path = require('path')

module.exports = {
  dev: {

    // Paths
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    proxyTable: {

        'api':{
           target:"http://localhost:8001",//后端请求域和端口
           changeOrigin:true,
           pathRewrite:{
              '^/api':''
           },
       }
    },

    // Various Dev Server settings
    //host: 'localhost', // can be overwritten by process.env.HOST

• 写一个简单的get请求

# src/components/HelloWorld.vue

<script>
export default {
  name: 'HelloWorld',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
},
methods:{
   firstGet(){
       this.$http.get('api/admin/move_article/test').then(response => {
           console.log(response)
           this.$message(response.data.msg);
        }, response => {
          console.log('error');
        });
     }
  },
created(){
    this.firstGet();
  }
}
</script>
