分页显示数据

rest_framework 里面封装了有分页功能的组件，直接可以拿来即用

在courses/views.py 中新建一个分页器类 （类的嵌套）

from rest_framework.pagination import PageNumberPaginationclass StandardPageNumberPagination(PageNumberPagination):page_size_query_param = 'page_size'max_page_size = 1class CourseAPIView(ListAPIView):queryset = Course.objects.filter(status=0).order_by("-orders","-students")# 设置过滤的字段filter_fields = ('course_category',)serializer_class = CourseSerializerfilter_backends = [OrderingFilter]ordering_fields = ('id', 'students', 'price', 'course_category')pagination_class = StandardPageNumberPagination

客户端请求后端发送数据

CKEditor富文本编辑器

富文本即具备丰富样式格式的文本。在运营后台，运营人员需要录入课程的相关描述，可以是包含了HTML语法格式的字符串。为了快速简单的让用户能够在页面中编辑带html格式的文本，我们引入富文本编辑器。

富文本编辑器：ueditor、ckeditor、kindeditor

1. 安装

pip install django-ckeditor

2. 添加应用

在INSTALLED_APPS中添加

INSTALLED_APPS = [...'ckeditor',  # 富文本编辑器'ckeditor_uploader',  # 富文本编辑器上传图片模块
    ...
]

3. 添加CKEditor设置

在settings/dev.py中添加

# 富文本编辑器ckeditor配置
CKEDITOR_CONFIGS = {'default': {'toolbar': 'full',  # 工具条功能'height': 300,      # 编辑器高度# 'width': 300,     # 编辑器宽
    },
}
CKEDITOR_UPLOAD_PATH = ''  # 上传图片保存路径，留空则调用django的文件上传功能

4. 添加ckeditor路由

在总路由中添加

path(r'^ckeditor/', include('ckeditor_uploader.urls')),

5. 为模型类添加字段

ckeditor提供了两种类型的Django模型类字段

  • ckeditor.fields.RichTextField 不支持上传文件的富文本字段

  • ckeditor_uploader.fields.RichTextUploadingField 支持上传文件的富文本字段\

修改course/models.py里面的字段信息,记得要重新数据迁移

from ckeditor_uploader.fields import RichTextUploadingField
class Course(models.Model):"""专题课程"""...brief = RichTextUploadingField(max_length=2048, verbose_name="课程概述", null=True, blank=True)

因为接下来的组件中使用了vue-video视频播放组件，所以我们需要先预安装。

安装依赖  （前端）

npm install vue-video-player --save

在main.js中注册加载组件require('video.js/dist/video-js.css');
require('vue-video-player/src/custom-theme.css');
import VideoPlayer from 'vue-video-player'
Vue.use(VideoPlayer);

视频播放

项目中有两种视频：收费视频[需要加密]和免费视频

使用保利威云视频服务来对视频进行加密

官方网址: http://www.polyv.net/vod/

注意：

开发时通过免费试用注册体验版账号

公司使用酷播尊享版

开发文档地址:http://dev.polyv.net/2017/videoproduct/v-playerapi/html5player/html5-docs/

要开发播放保利威的加密视频功能,需要在用户中心->设置->API接口和加密设置.

http://my.polyv.net/secure/setting/api

配置视频上传加密.

上传视频并记录视频的VID

后端获取保利威的视频播放授权token,提供接口api给前端

参考文档:http://dev.polyv.net/2019/videoproduct/v-api/v-api-play/create-playsafe-token/

根据官方文档的案例,已经有其他人开源了,针对polvy的token生成的python版本了,我们可以直接拿来使用.

在libs下创建polyv.py,编写token生成工具函数

from django.conf import settings
import time
import requests
import hashlibclass PolyvPlayer(object):userId = settings.POLYV_CONFIG['userId']secretkey = settings.POLYV_CONFIG['secretkey']def tomd5(self, value):"""取md5值"""return hashlib.md5(value.encode()).hexdigest()# 获取视频数据的tokendef get_video_token(self, videoId, viewerIp, viewerId=None, viewerName='', extraParams='HTML5'):""":param videoId: 视频id:param viewerId: 看视频用户id:param viewerIp: 看视频用户ip:param viewerName: 看视频用户昵称:param extraParams: 扩展参数:param sign: 加密的sign:return: 返回点播的视频的token"""ts = int(time.time() * 1000)  # 时间戳plain = {"userId": self.userId,'videoId': videoId,'ts': ts,'viewerId': viewerId,'viewerIp': viewerIp,'viewerName': viewerName,'extraParams': extraParams}# 按照ASCKII升序 key + value + key + value... + value 拼接plain_sorted = {}key_temp = sorted(plain)for key in key_temp:plain_sorted[key] = plain[key]print(plain_sorted)plain_string = ''for k, v in plain_sorted.items():plain_string += str(k) + str(v)print(plain_string)sign_data = self.secretkey + plain_string + self.secretkey# 取sign_data的md5的大写sign = self.tomd5(sign_data).upper()# 新的带有sign的字典plain.update({'sign': sign})result = requests.post(url='https://hls.videocc.net/service/v1/token',headers={"Content-type": "application/x-www-form-urlencoded"},data=plain).json()data = {} if isinstance(result, str) else result.get("data", {})return {"token": data}

View Code

配置文件settings/dev.py，代码

# 保利威视频加密服务
POLYV_CONFIG = {"userId":"注册获取","secretkey":"注册获取","servicesUrl":"https://hls.videocc.net/service/v1/token",
}

视图代码:

from rest_framework.response import Response
from luffy.utils.polyv import PolyvPlayerfrom rest_framework.views import APIView
class PolyvAPIView(APIView):def get(self, request):vid = request.query_params.get("vid")remote_addr = request.META.get("REMOTE_ADDR")user_id = 1  # 测试使用user_name = "test"  # 测试使用polyv_video = PolyvPlayer()verify_data = polyv_video.get_video_token(vid, remote_addr, user_id, user_name)return Response(verify_data["token"])

路由代码：

path(r"polyv/token/",views.PolyvAPIView.as_view()),

客户端请求token并播放视频

在 vue项目的入口文件index.html 中加载保利威视频播放器的js核心类库

<script src='https://player.polyv.net/script/polyvplayer.min.js'></script>

创建视频播放页面的组件Player.vue，组件中直接配置保利威播放器需要的参数。

Player.vue，代码：

<template><div class="player"><div id="player"></div></div>
</template><script>
export default {name:"Player",data () {return {}},methods: {},mounted(){let _this = this;var player = polyvObject('#player').videoPlayer({wrap: '#player',width: document.documentElement.clientWidth, // 宽度
        height: document.documentElement.clientHeight, // 高度
        forceH5: true,vid: '62dc475e3f09b6db69447011eed4415a_6',code: '骑士3期', // 一般是用户昵称// 视频加密播放的配置
        playsafe: function (vid, next) { // 向后端发送请求获取加密的token
            _this.$axios.get(_this.$settings.Host+`/courses/polyv/token/`,{params:{vid: "62dc475e3f09b6db69447011eed4415a_6",}}).then(function (response) {console.log(response);next(response.data.token);})}});},computed: {}
}
</script><style scoped>
</style>

View Code

前端路由，代码：

   {name:"Player",path:"/player",component: Player,},

完善点击课程详情页的立即试学按钮跳转到视频播放页面，并发送vid

Detail.vue，代码：

课时章节：

<button class="try" v-if="lesson.free_trail"><router-link :to="{path: '/player',query:{'vid':lesson.section_link}}">立即试学</router-link></button>

View Code

Player.vue，代码：

获取vid视频ID

<template><div class="player"><div id="player"></div></div>
</template><script>
export default {name:"Player",data () {return {}},methods: {},mounted(){let _this = this;let video_id = this.$route.query.vid;var player = polyvObject('#player').videoPlayer({wrap: '#player',width: document.documentElement.clientWidth, // 宽度
        height: document.documentElement.clientHeight, // 高度
        forceH5: true,vid:video_id, // vid:vid,的简写
        code: '骑士3期', // 一般是用户昵称// 视频加密播放的配置
        playsafe: function (vid, next) { // 向后端发送请求获取加密的token

完善API接口的身份认证

试学必须在用户登录以后才能进行，所以后端的tokenAPI接口必须保证用户登陆以后，

所以后端视图代码中增加对jwt token的识别认证，代码:

from rest_framework.views import APIView
from luffy.libs.polyv import PolyvPlayer
from rest_framework.response import Response
from rest_framework.permissions import IsAuthenticated
class PolyvAPIView(APIView):"""生成播放视频的playsafetoken""""""播放页面的当前访问者只能是用户,不能是游客"""permission_classes = (IsAuthenticated,)def get(self,request):# 获取客户端要播放的视频vidvid = request.query_params.get("vid")# 获取客户端的IP地址remote_addr = request.META.get("REMOTE_ADDR")# 获取用户的ID和用户名[测试]user_id = request.user.iduser_name = request.user.username# 生成tokenpolyv = PolyvPlayer()data = polyv.get_video_token(vid, remote_addr,user_id, user_name)return Response(data["token"])

前端在请求后端提供视频加密播放的token时需要附带 jwt token

Player.vue,代码:

<template><div class="player"><div id="player"></div></div>
</template><script>
export default {name:"Player",data () {return {token: sessionStorage.token || localStorage.token,user_id: sessionStorage.user_id || localStorage.user_id,user_name: sessionStorage.user_name || localStorage.user_name,}},methods: {},created(){// 判断用户用户是否已经登录了if(!this.token){let _this = this;this.$alert("对不起,您尚未登录!请登录!","警告",{callback(){_this.$router.push("/login");}})}},mounted(){let _this = this;let video_id = this.$route.query.vid;var player = polyvObject('#player').videoPlayer({wrap: '#player',width: document.documentElement.clientWidth, // 宽度
        height: document.documentElement.clientHeight, // 高度
        forceH5: true,vid:video_id, // vid:vid,的简写
        code: _this.user_name, // 跑马灯的显示信息,一般是用户昵称// 视频加密播放的配置
        playsafe: function (vid, next) { // 向后端发送请求获取加密的token
            _this.$axios.get(_this.$settings.Host+`/courses/polyv/token/`,{// 附带jwt token
              headers:{// 注意下方的空格!!!"Authorization":"jwt " + _this.token},params:{vid:video_id,}}).then(function (response) {console.log(response);next(response.data.token);})}});},computed: {}
}
</script><style scoped>

详情页的视频免费播放

在课程模型Courses/models.py中新增一个视频的字段

from ckeditor_uploader.fields import RichTextUploadingField
class Course(BaseModel):"""专题课程"""video = models.FileField(upload_to="video", null=True,blank=True,default=None, verbose_name="封面视频")

执行数据迁移

python manage.py makemigrations
python manage.py migrate

前端修改播放器中关于视频地址和视频封面的地址

watch:{course(data){// 替换视频地址this.playerOptions.sources[0].src = data.video;// 替换视频封面this.playerOptions.poster = data.course_img;// 替换科恒信息中的详情介绍里面的图片路径while(data.brief.search(`"/media`) != -1 ){data.brief = data.brief.replace(`"/media`,`"${this.$settings.Host}/media`)}},
