1.1 路由跳转的两种方式

# html中路由的跳转
<router-link to="/">
    <img src="../assets/img/head-logo.svg" alt="">
</router-link>

    .slogan {
        background-color: #eee;
        height: 40px;

    .slogan p {
         1200px;
        margin: 0 auto;
        color: #aaa;
        font-size: 13px;

    }

    .right-part span {
        line-height: 68px;
        cursor: pointer;
    }
</style>

1.3 配置全局的settings和css

• 在 assets下的js中加入settings.js

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

• 在assets下的css中加入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 */
}

• 在main.js中配置

//配置全局样式，@代表src的路径
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'

1.4 前台配置

# 安装相关框架
cnpm install axios
cnpm install vue-cookies
cnpm install element-ui
cnpm install jquery
cnpm install bootstrap@3

• 配置axios

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

• 配置vue-cookies

import cookies from 'vue-cookies'
Vue.prototype.$cookies = cookies;

• ElementUI的配置

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI);

• bootstrap配置

import 'bootstrap'
import 'bootstrap/dist/css/bootstrap.min.css'

• jquery的配置

# 项目根路径创建一个 vue.config.js

const webpack = require("webpack");

module.exports = {
    configureWebpack: {
        plugins: [
            new webpack.ProvidePlugin({
                $: "jquery",
                jQuery: "jquery",
                "window.jQuery": "jquery",
                "window.$": "jquery",
                Popper: ["popper.js", "default"]
            })
        ]
    }
};
