视频加密流程图:

Python django框架 web端视频加密的实例详解

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/

在utils下创建polyv.py,编写token生成工具函数,path:utils/polyv.py
utils 是多个模块的公共函数库的文件夹里面存放自己开发的组件

from django.conf import settings
import time
import requests
#pip install requests
import hashlib



class PolyvPlayer(object):
  def __init__(self,userId,secretkey,tokenUrl):
    """初始化,提供用户id和秘钥"""
    self.userId = userId
    self.secretKey = secretkey
    self.tokenUrl = tokenUrl


  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,

    }

    # 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]

    plain_string = ''
    for k, v in plain_sorted.items():
      plain_string += str(k) + str(v)

    # 首尾拼接上秘钥
    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})
    # python 提供的发送http请求的模块
    result = requests.post(

      url=self.tokenUrl,
      headers={"Content-type": "application/x-www-form-urlencoded"},
      data=plain     # 平台所需要携带的数据
    ).json() # json.loads 把那拿到的数据序列化
    token = {} if isinstance(result, str) else result.get("data", {})  # 如果保利威视频平台返回的的字符串 token={} 否则
    if token == '':
      return result
    return token

在 项目开发时的本地配置 配置参数:
配置文件settings/dev.py,代码:

# 保利威视频加密服务
POLYV_CONFIG = {
  "userId":"62dc475e3f",
  "secretkey":"h6FiaEBRMU",
  "tokenUrl":"https://hls.videocc.net/service/v1/token",
}

Python django框架 web端视频加密的实例详解

urls.py,主路由代码:

path(r'polyv/',include('polyv.urls')),

在项目主应用文件夹下创建app
命令:
cd 主应用文件夹下
python3 …/…/manage.py startapp polyv

urls.py,子路由代码:

from django.urls import path,re_path
from . import views

urlpatterns = [
  path('video/',views.Video.as_view(),)

]

polyv/views.py,视图代码:

from django.shortcuts import render

# Create your views here.
from rest_framework import status
from lyapi.utils.polyv import PolyvPlayer
from rest_framework.views import APIView
from rest_framework.permissions import IsAuthenticated
from django.conf import settings
from rest_framework.response import Response


class VideoView(APIView):
  # vid = '348e998797383060cb19620b1c600203_3'
  # permission_classes = [IsAuthenticated, ]       #from rest_framework.permissions import IsAuthenticated 登录认证
  def get(self,request):
    polyv_obj = PolyvPlayer(settings.POLYV_CONF['userid'],settings.POLYV_CONF['secretKey'],settings.POLYV_CONF['tokenUrl'])   # 调用polyv文件下的polyv_obj类
    # vid = 'cee1047a76927eb43774263cd93bb69f_c'    # 存在保利威平台的视频ID
    # vid = '348e998797383060cb19620b1c600203_3'     # 存在保利威平台的视频ID
    vid = request.query_params.get('vid')				# 需要把保利威平台的视频ID存在数据库里或者直接或者在前段直接在的Params加 vid cee1047a76927eb43774263cd93bb69f_c
    viewerIp = request.META.get('REMOTE_ADDR')     # 获取用户访问的IP地址
    viewerId = request.user.id             # 获取用户的id
    viewerName = request.user.username         # 获取用户的账号名

    token_dict = polyv_obj.get_video_token(vid,viewerIp,viewerId,viewerName)    # 调用polyv文件下的polyv_obj类下的get_video_token方法
    print(token_dict)

    if 'code' in list(token_dict) and token_dict['code'] != 200:            # 返回请求失败的信息
      return Response(token_dict, status=status.HTTP_403_FORBIDDEN)
    '''
    返回结果:
    {
      "code": 403,
      "status": "error",
      "message": "invalid userId or videoId.",
      "data": ""
    }
    
    '''

    return Response(token_dict)             # 返回请求成功的信息

    '''
    返回结果:
      {
        "token": "43883858-92a3-4f25-a6e8-701d10d88cde-f2",
        "userId": "cee1047a76",
        "appId": null,
        "videoId": "cee1047a76927eb43774263cd93bb69f_c",
        "viewerIp": "127.0.0.1",
        "viewerId": "2",
        "viewerName": "root",

    '''

到这里后端的api接口就已经写好啦!
前段 vue界面 简写:
在src下的components下新建一个Player.vue

# Player.vue

<template>
  <div class="player">
   <div id="player">

   </div>
  </div>
</template>

<script>
export default {
 name:"Player",
 data () {
  return {

  }
 },


 mounted() { //如果需要对标签进行一些加工处理,然后再放数据时,需要用mounted这个钩子函数,如果单纯的是获取数据,添加到数据属性中
        // 那么用created方法

  this.get_video_data();

 },

 methods: {
    get_video_data(){
     let user_name = localStorage.username || sessionStorage.username; //token认证
    let token = localStorage.token || sessionStorage.token;				//token认证
    console.log(this.$route.params.vid)
     let self = this;
    var player = polyvPlayer({
     wrap: '#player',
     width: document.documentElement.clientWidth - 300,
     height: document.documentElement.clientHeight,
     vid: this.$route.params.vid,
     // forceH5: true,

     // code: user_name,
     playsafe: (vid, next) =>{
      console.log(self)
      self.$axios.get(`${self.$settings.Host}/polyv/video/"htmlcode">
import Vue from 'vue'
import Router from 'vue-router'
import Home from '@/components/Home'
import Login from '@/components/Login'
import Register from "@/components/Register";
import Course from "@/components/Course"
import Detail from "@/components/Detail";
import Cart from "@/components/Cart";
import Order from "@/components/Order";
import Player from "@/components/Player";	//Player组件的url 需要复制这里,其他的url忽略
import Myorder from "@/components/Myorder";	 
Vue.use(Router)

export default new Router({
 mode:'history',
 routes: [
  {
   path: '/',
   //name: 'heme',
   component: Home
  },
    {
   path: '/home',
   //name: 'heme',
   component: Home
  },
    {
   path: '/user/login',
   //name: 'heme',
   component: Login
  },
    {
   path: '/register',

   //name: 'heme',
   component: Myorder
  },
  {//Player组件的url 需要复制这个括号里的,其他的url忽略
   path: '/polyv/player/:vid',
   //name: 'heme',
   component: Player
  },

 ]
})

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
