29-课程详情页之前台

课程详情页之前台

一、流程

'''
1. 课程详情页面创建 FreeCourseDetail.vue
2. 配置课程详情页面路由 /free/detail/:id
3. 课程详情页面从路由中获取 this.$route.params.id
4. 直接拿课程详情页面
5. 下载视频组件 vue-video-player
6. main.js中配置刚刚下载好的视频组件vue-video-player
'''

二、依赖：在柳扶风因此同意目录下的命令

npm install vue-video-player

三、配置：main.js

// vue-video播放器
require('video.js/dist/video-js.css');
require('vue-video-player/src/custom-theme.css');
import VideoPlayer from 'vue-video-player'
Vue.use(VideoPlayer);

四、资源：图片防止asset/ing文件夹下

"""
enum.svg
chapter-player.svg
cart-yellow.svg
"""

五、路由：router.js

import FreeCourseDetail from './views/FreeCourseDetail.vue'
export default new Router({
    routes: [
        // ...
        {
            path: '/free/detail/:pk',
            name: 'free-detail',
            component: FreeCourseDetail
        }
    ]
}

六、组件
