视频播放组件：vue-core-video-player的使用
# 第一步：安装 npm install --save vue-core-video-player
# 第二步：main.js 引入
import VueCoreVideoPlayer from 'vue-core-video-player'
Vue.use(VueCoreVideoPlayer) # 默认是英文的
# 第二步(补充)国际化
Vue.use(VueCoreVideoPlayer, {
lang: 'zh-CN'
})
# 第三步：在组件的html中使用
<div id="app">
<div class="player-container">
<vue-core-video-player src="http://img.ksbbs.com/asset/Mon_1703/05cacb4e02f9d9e.mp4"></vue-core-video-player>
</div>
</div>
https://www.cnblogs.com/liuqingzheng/p/16204851.html # 组件详细说明
https://github.com/core-player/vue-core-video-player-examples
4、课程详情接口
# 课程列表(所有课程:分页，排序。。。)，再加一个课程详情
# 基于原来的课程列表接口，只需要再加入继承一个类：RetrieveModelMixin
class CourseView(GenericViewSet, ListModelMixin,RetrieveModelMixin):
queryset = Course.objects.all().filter(is_delete=False, is_show=True).order_by('orders')
serializer_class = CourseSerializer
5、课程章节接口
思路# 查询所有章节---》章节跟课程有关联，根据课程id号，过滤章节 # 比如：查询课程id为1的所有章节 # 本质就是查询所有章节，带过滤功能
路由
router.register('chapter', CourseChapterView, 'chapter')
课程章节接口
class CourseChapterView(GenericViewSet, ListModelMixin):
queryset = CourseChapter.objects.all().filter(is_show=True,is_delete=False).order_by('orders')
serializer_class =CourseChapterSerializer
filter_backends = [DjangoFilterBackend]
# 加入过滤---》按照课程id过滤--》第三方django-filter
filter_fields = ['course_id']
序列化类
class CourseSectionSerializer(serializers.ModelSerializer):
class Meta:
model = CourseSection
fields = ['name', 'orders', 'section_link', 'duration', 'free_trail']
class CourseChapterSerializer(serializers.ModelSerializer):
# 使用子序列化
coursesections = CourseSectionSerializer(many=True)
class Meta:
model = CourseChapter
# CourseChapter表中隐藏了一个coursesections字段，对象.coursesections
fields = ['id', 'name', 'chapter', 'summary', 'coursesections'] # 返回该章节下的课时
6、搜索功能接口
思路
# 搜索功能--》配合搜索接口
# 类比：淘宝，京东，抖音，微博，百度---》这个接口本应该是最复杂，最有技术含量的接口
-不同的人搜出来的结果都不一样，因为有个性化推荐
-淘宝搜 [连体衣]--->【电饭煲】 199以下
# 咱们是最简单的实现，后期学完es：分布式全文检索引擎，基于es，写个百度
# 正常来讲：搜索可以搜索所有类型课程---》免费课，实战课，轻课--》咱们只写了实战课，只能搜出实战课
# 咱么如果只有实战课，实际上可以和查询所有实战课课程接口放一起---》为了方便后期的扩展，我们要单独写
# 咱么你的可以按照课程名字模糊匹配
# 速度慢的问题---》总共课程就不多--》mysql完全顶得住
# 课程名字和id 在redis中缓存
# 只要用搜索，对数量比较大，就上专业的搜索引擎---》es ---》倒排索引
# http://127.0.0.1:8000/api/v1/course/search/?search=%E5%85%A5%E9%97%A8
View Code
视图类
# 只针对于实战课的搜索接口
class CourseSearchView(GenericViewSet, ListModelMixin):
queryset = Course.objects.all().filter(is_delete=False, is_show=True).order_by('orders')
serializer_class = CourseSerializer
filter_backends = [SearchFilter]
search_fields = ['name', ]
# 加入分页类
pagination_class = CommonPageNumberPagination
# 方便后期扩展
# def list(self, request, *args, **kwargs):
# # 这个查的是实战课
# res=super().list(request, *args, **kwargs)
# # res2=查询免费课
# # res3=查询轻课
#
# # 上面全是取数据库查询
# # 后期改成取es中查询，
# return APIResponse(result={'free_course':'字典','actual_course':res.data})
View Code
7、搜索功能前段
思路
# 头部组件中的搜索框 # 搜索结果展示页面
搜索结果展示页面 header.vue

8、视频托管
什么是视频托管
# 为什么会用到视频托管平台
图片，视频，一般不放在自己项目中，因为只要访问一次图片，就向后端发一次请求，会消耗服务器资源
所以，我们通常把静态类型文件，托管到第三方平台，这个操作会花钱，它使用的是第三方平台的服务器资源和带宽
# 视频托管到云平台了
-阿里 oss
-七牛云存储。。。
# 公司里托管视频的多种方案
1.托管到云平台：阿里 oss， 七牛云存储
2.公司自己搭建文件服务器
-fastdfs：搭建笔记 搭建完毕用python上传（上传比较麻烦）：https://zhuanlan.zhihu.com/p/372286804
-Minio：自己搭建Minio，阿里云上--》搭建笔记--》上传下载比较简单
-图形化界面后台，登陆上看到文件
-ceph：大型文件服务器，搭建比较码放
3.如果文件小可以直接放到项目中
# 七牛云---》国内go语言推崇者--》项目基本都是go开发的---》许式伟
我们的项目使用七牛云托管视频，七牛云是国内go语言推崇者，项目基本都是go开发的，掌门许式伟
go的国内镜像：goproxy.cn 就是七牛云的
-豆瓣python---》python写的
# 七牛云上传
-手动上传---》手动配置视频地址--（不采取）
-前端上传，返回连接地址，提交到咱们自己的后端，存到数据库
-前端把视频传到咱们后端，咱们后端通过python传到七牛云，生成连接，存到数据库:https://developer.qiniu.com/kodo/1242/python
View Code
七牛云快速使用
左上角—点击展开产品浮层—对象存储kodo—空间管理—新建空间
存储空间名称（不允许重复）—存储区域—访问控制
空间创建成功—绑定域名/立即绑定自定义域名（使用立即绑定自定义域名，平台会分配一个30天的试用域名）
文件管理—上传文件—选择文件
空间设置—可以选择访问控制为共有/私有
生成文件链接
可以把文件链接放入数据库中
七牛云上传文件
from qiniu import Auth, put_file, etag
q = Auth('--', '-') # 个人中心——秘钥管理
#要上传的空间
bucket_name = 'lqz'
#上传后保存的文件名
key = '致命诱惑.png'
#生成上传 Token，可以指定过期时间等
token = q.upload_token(bucket_name, key, 3600)
#要上传文件的本地路径
localfile = './default.png'
ret, info = put_file(token, key, localfile, version='v2')
print(info)
