封装基础网络请求，前后端联调请求后端接口

npm install axios -S

src/network/requestConfig.js

import axios from 'axios';
import store from "@/store";
export function request(config){
	const instance = axios.create({
		baseURL:"http://127.0.0.1:8000/",
		// baseURL:process.env.VUE_APP_BASE_URL,
		timeout:5000,
	})
	
	// 请求拦截
	instance.interceptors.request.use(config=>{
		// 一般来说我们会在这里边给一些实例加上token
		const token = window.localStorage.getItem("token");
		if(token){
			// config.headers.Authorization="token";
			config.headers.Authorization=token;
		}
		
		// 直接放行
		return config;
	},err=>{
		// 这里写一些错误的代码在这里
	})
	
	// 响应拦截
	instance.interceptors.response.use(res=>{
		if(res.data.status==false){
			window.localStorage.setItem("token","");
			store.commit("setIsLogin",false);
		}

		return res.data?res.data:res;
	},err=>{
		// 响应错误的在这里处理，比如404  500这些特殊的状态码
		// 咱们跳转一个特定的处理页面
	})
	
	return instance(config);
} 

src/network/home.js

import {request} from "./requestConfig.js"


export function getMainMenu(){
	return request({
		url:"/main_menu",
	})
}

测试

<script setup>
	import {getMainMenu} from "@/network/home"
	getMainMenu().then(res=>{
		console.log(res)
	})
</script>

配置基础 router 信息

src/router/index.js

import { createRouter, createWebHistory } from 'vue-router'
import HomeView from '../views/HomeView.vue'

const routes = [
  {
    path: '/',
    name: 'home',
    component: HomeView,
    meta:{
      title:"慕西商城首页"
    }
  },

]

const router = createRouter({
  history: createWebHistory(process.env.BASE_URL),
  routes
})

router.beforeEach((to,from)=>{
	document.title = to.meta.title;
})

export default router

src/views/HomeView.vue

<template>
    <p>首页</p>
</template>

慕西商城首页顶层标题栏开发

src/assets/css/config.css
全局配置

@import './base.css';
/*定义全局变量*/
:root {
    --font-red: #f10215;
    --font-gray: #999;
    --content-width:1200px;
	--el-color-danger:#e2231a !important;
}

main.js
全局引入

import "@/assets/css/config.css"

这个宽度是1200 引用在src/assets/css/config.css全局中设置–content-width

<template>
    <div class="wrapper">
        <div class="header">
            <a href="#">你好，请登录</a>
             <a href="#">免费注册</a> |
              <a href="#">我的订单</a>
        </div>
    </div>
</template>

<style lang="less" scoped>
    //最外层
    .wrapper{
        background-color: #e3e4e5;
        height: 30px;
        .header{
            //引用全局变量中的宽度变量
            width: var(--content-width);
            margin: 0 auto;   //居中
            text-align: right; //右对齐
            line-height: 30px;  //上下对齐
            a{
                color: var(--font-gray);
                // 鼠标滑过的效果
                &:hover{
                    color: var(--font-red);
                }
                margin-left: 10px;
            }

        }
    }
</style>

取地址符空格增加免费注册和右边分割线的距离

<a href="#">免费注册</a> &nbsp;&nbsp;|

也可以把免费注册设置为一直是红色的

慕西商城首页头部结构开发

            border: 1px solid red;
        }

        .search-box{
            width: 800px;
        }
