前台vue配置

前台

vue环境

1.傻瓜式安装node: 
官网下载：https://nodejs.org/zh-cn/

2.安装cnpm: 
>: npm install -g cnpm --registry=https://registry.npm.taobao.org

3.安装vue最新脚手架: 
>: cnpm install -g @vue/cli

注：如果2、3步报错，清除缓存后重新走2、3步
>: npm cache clean --force

创建项目

"""
前提：在目标目录新建luffy文件夹
>: cd 建立的luffy文件夹
>: vue create luffycity
"""

全局配置：全局样式、配置文件

global.css

/* 声明全局样式和项目的初始化样式 */
body, h1, h2, h3, h4, h5, h6, p, table, tr, td, ul, li, a, form, input, select, option, textarea {
    margin: 0;
    padding: 0;
    font-size: 15px;
}

a {
    text-decoration: none;
    color: #333;
}

ul {
    list-style: none;
}

table {
    border-collapse: collapse; /* 合并边框 */
}

settings.js

export default {
    base_url: 'http://127.0.0.1:8000'
}

main.js

// 配置全局样式
import '@/assets/css/global.css'

// 配置全局自定义设置
import settings from '@/assets/js/settings'
Vue.prototype.$settings = settings;
// 在所有需要与后台交互的组件中：this.$settings.base_url + '再拼接具体后台路由'
