Vue - vue-admin-template模板项目改造：增加TopHeader（顶栏）

GitHub Demo 地址

在线预览

前言

demo中的项目已经添加了TagsView功能和权限控制
关于TagsView功能的添加可以看：Vue - vue-admin-template模板项目改造：增加TagsView功能

有时项目需要在顶部显示一个header，在顶栏中显示项目标题和用户信息，这时需要对模块项目进行改造
demo项目中在原有的基础上进行了扩展，即可以支持原有方式展示，又可以通过setting配置显示顶栏

效果图

tagsView

topHeader + 隐藏logo

topHeader+fixedHeader

topHeader+fixedHeader+tagsView

涉及文件

因为顶栏要显示标题和用户信息，顶栏下方要显示面包屑和tagsView，所以新增了topHeader和Hamburger文件
原有代码改造涉及layout 和 setting相关文件，主要是在src\layout\index.vue文件进行功能扩展

src\layout\components\index.js
src\layout\index.vue
src\store\modules\settings.js
src\settings.js

涉及代码

src\layout\components\index.js 新增

export { default as TopHeader } from './TopHeader/TopHeader.vue' // TopHeader
export { default as Hamburger } from './TopHeader/Hamburger.vue' // Hamburger

src\layout\index.vue 全部代码
