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)

效果：

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

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);

注册路由

routers/index.js

import CourseDetail from "../components/CourseDetail"

    ,{
      name:"CourseDetail",
      path: "/detail",
      component: CourseDetail,
    }

完善从课程列表跳转到课程详情的链接

Course.vue:31行,代码:

<p class="box-title"><router-link :to="{path: '/detail',query:{id:course.id}}">{{course.name}}</router-link></p>

CourseDetail.vue:104行,接受来自课程列表的课程ID, 代码:

  mounted(){
    // 获取地址上面的课程ID
    let id = this.$route.query.id - 0;
    console.log(id);
    if( isNaN(id) || id < 1 ){
      alert("非法请求!")
      this.$router.go(-1);
    }
  }

后端提供课程详情页数据接口

序列化器代码:

class TeacherDetailModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = Teacher
        fields = ("id","name","title","role","signature","image","brief")


class CourseDetailModelSerializer(serializers.ModelSerializer):
    """课程详情页的序列化器"""
    teacher = TeacherDetailModelSerializer()
    class Meta:
        model = Course
        fields = ("id","name","course_img","students","lessons","pub_lessons","price","teacher","course_level","brief")

视图代码:

from rest_framework.generics import RetrieveAPIView
from .serializers import CourseDetailModelSerializer
class CourseDeitalAPIView(RetrieveAPIView):
    queryset = Course.objects.filter(is_delete=False, is_show=True).order_by("orders")
    serializer_class = CourseDetailModelSerializer

路由代码:

from django.urls import path, re_path
from . import views
urlpatterns = [
    re_path(r"detail/(?P<pk>\d+)",views.CourseDetailAPIView.as_view())
]

前端请求api接口并显示数据

课程播放

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.

配置视频上传加密.

上传视频并记录视频的ID

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/

视图代码:

from rest_framework.response import Response
from luffy.utils.polyv import PolyvPlayer

from 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
        user_name = "test"
        polyv_video = PolyvPlayer()
        verify_data = polyv_video.get_video_token(vid, remote_addr, user_id, user_name)
        return Response(verify_data["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utils下创建polyv.py,编写token生成工具函数

from django.conf import settings
import time
import requests
import hashlib

class 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token
    def 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}

客户端请求token并播放视频

在 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>

在组件中,直接配置保利威播放器需要的参数:

<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,
        height: document.documentElement.clientHeight,
        forceH5: true,
        vid: '06e090212218afd78ccadfcc3b954385_0',
        code: 'myRandomCodeValue',
        // 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+`/course/video/${vid}/`).then(function (data) {
                console.log(data);
                next(data.data.token)
            })

        }
    });
  },
  computed: {
  }
}
</script>

<style scoped>
</style>

完善点击课程详情的立即试学按钮跳转到视频播放页面

<span class="btn2"><router-link :to="{path: 'player',query:{vid:'06e090212218afd78ccadfcc3b954385_0'}}">免费试学</router-link></span>

完善API接口的身份认证

后端视图代码

from rest_framework.views import APIView
from rest_framework.permissions import IsAuthenticated
from utils.polyv import PolyvPlayer
from rest_framework.response import Response
class CoursePlayerAPIView(APIView):
    """实际上而言,需要在播放页面保存当前访问者只能是用户,不能是游客"""
    permission_classes = (IsAuthenticated,)
    """生成保利威视频播放的token"""
    def get(self,request,vid):
        """生成token"""
        # 获取视频浏览者的IP
        remote_addr = request.META.get("REMOTE_ADDR")
        # user_id = request.user.id  # 用户ID
        user_id = 1
        # user_name = request.user.username # 用户名
        user_name = "admin"
        # 引入utils下刚刚声明的保利威工具类
        polyv_video = PolyvPlayer()
        verify_data = polyv_video.get_video_token(vid, remote_addr, user_id, user_name)
        return Response(verify_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:

<script>
export default {
  name:"Player",
  data () {
    return {
      user_id: sessionStorage.user_id || localStorage.user_id,
      token: sessionStorage.token || localStorage.token,
    }
  },
  methods: {

  },
  mounted(){
    let _this = this;
    let vid = this.$route.query.vid;
    var player = polyvObject('#player').videoPlayer({
        wrap: '#player',
        width: document.documentElement.clientWidth,
        height: document.documentElement.clientHeight,
        forceH5: true,
        vid: vid,
        code: 'myRandomCodeValue',
        // 视频加密播放的配置
        playsafe: function (vid, next) {// 向后端发送请求获取加密的token
            _this.$axios.get(_this.$settings.host+`/course/video/${vid}/`,
              // 因为本次访问的api接口设置了身份认证,所以在请求头中必须附带token值
              {
                headers:{
                  // 附带已经登录用户的jwt token 提供给后端,一定不能疏忽这个空格
                  'Authorization':'JWT '+_this.token
                },
              }).then(function (data) {
                console.log(data);
                next(data.data.token)
            }).catch(error=>{
                alert("非法请求");
                _this.$router.go(-1);
            })
        }
    });
  },
  computed: {
  }
}
</script>
