Luffy项目：4、导入/出项目依赖，前端主页设计，轮播图组件前后端对接
Luffy项目
一、导入项目依赖
为什么导出项目依赖：
本地开发环境和项目上线依赖的环境不相同，所以需要导出项目依赖
如何导出项目依赖：
导出项目依赖的方法有两种，第一种是自己手动编写，第二种是使用插件
# 使用插件生成项目依赖
- 生成：pip freeze # 显示当前环境安装的所以依赖
pip freeze > requirements.txt # 将当前项目依赖生成一个txt文本
- 安装依赖
pip install -r requirements.txt # 上线环境环境
pip install -r dev.txt # 开发环境
二、前端主页功能
# 首页页面组件
# 头部组件(小组件)
# 轮播图组件(小组件)
# 尾部组件(小组件)
1、header组件
<template>
<div class="header">
<div class="slogan">
<p>老男孩IT教育 | 帮助有志向的年轻人通过努力学习获得体面的工作和生活</p>
</div>
<div class="nav">
<ul class="left-part">
<li class="logo">
<router-link to="/">
<img src="../assets/img/head-logo.svg" alt="">
</router-link>
</li>
<li class="ele">
<span @click="goPage('/free-course')" :class="{active: url_path === '/free-course'}">免费课</span>

</template>
<script>
export default {
name: "Header",
data() {
return {
// 当前所在路径，去sessionStorage取的，如果取不到，就是 /
url_path: sessionStorage.url_path || '/',
}
},
methods: {
goPage(url_path) {
// 已经是当前路由就没有必要重新跳转
if (this.url_path !== url_path) {
this.$router.push(url_path);
}
sessionStorage.url_path = url_path;
},
},
created() {
// 组件加载万成，就取出当前的路径，存到sessionStorage this.$route.path
sessionStorage.url_path = this.$route.path;
// 把url_path = 当前路径
this.url_path = this.$route.path;
}
}
