梦学谷项目(下)
接上一篇的技术点分析，在整体项目汇中，由于在之前的项目中对mock.js假数据从未有过了解，所以对假数据的使用做出了总结。
第一步：
登录假数据平台：https://www.fastmock.site/#/，完成注册。
第二步：
创建新项目，设置项目的基准路径
第三步：
设置假数据，
设置假数据时，要注意的是请求数据时的数据路径也是需要进行设置的。
设置假的数据，在做项目的过程中，是为了方便在后端小伙伴还未完成接口的时候，方便我们能够提前的搭好框架。
小结：
通过对
axios的封装，能够方便我们日后对代码的维护。减少工作量。假数据的使用：可以很大程度的提高我们的工作进度
等这些准备工作都做完后，我们就可以进入我们的项目中进行逻辑的梳理。
纵观整个项目，其实技术点的体现并不明显，我们通过对axios的封装，以及mock.js假数据的使用，已经对整体项目的技术点已经有了体现，下面我通过会员管理模块的业务逻辑的梳理，对整个项目的技术点作出一个大概的总结。
首先：是对于api的封装
import request from '../utils/index'
export default {
list(page, size) {
return request({
url: `/userList/${
page}/${
size}`,
method: 'get',
})
},
add(addForm) {
return request({
url: `/mearge`,
method: 'post',
data: addForm,
})
},
del(id) {
return request({
url: `/del/${
id}`,
method: 'delete'
})
},
edit(id, editForm) {
return request({
url: `/edit/${
id}`,
method: 'put',
data: editForm
})
}
}

在会员管理中，由于修改用户跟添加用户对话框相同，通过
computed计算属性，设置状态，将修改用户的对话框跟添加用户的对话框写在一块，通过在不同的状态下，点击展示不同的对话框，从而节省代码，优化了页面。
封装面包屑导航
在components中新建bread文件，
<template>
<div class="bread">
<el-card>
<p>
<span></span>
<span v-for="(item, index) in breadList" :key="index">{
{
item }}</span>
</p></el-card
>
</div>
</template>
<script>
export default {
data() {
return {
breadList: [],
};
},
mounted() {
this.breadList = this.$route.meta.bread;
},
};
</script>
在router.js中
{
path: "/member",
component: () => import( /* webpackChunkName: "about" */ "../components/member.vue"),
meta: {
bread: ['会员管理']
}
},
在需要的页面中引入组件使用即可。
关于梦雪谷项目的技术难点，大概就是这些了，由于在没有其他特别突出的的项目难点。其余模块均可参考这一模块。完整代码请看梦学谷
