vue-video-player 断点续播的实现

清疚 2022-10-26 01:23 274阅读 0赞

最近的项目中需要实现视频断点续播的功能，一听到这个功能。内心方张了..但却又有点小窃喜，小懵乱。抱着求学态度去挑战一下。

1.安装插件  
1  
npm install vue-video-player --save  
2.Main.js 引入组件

import VideoPlayer from 'vue-video-player'  
require('video.js/dist/video-js.css')  
require('vue-video-player/src/custom-theme.css')  
Vue.use(VideoPlayer)  
3.页面使用组件

上面的 src视频地址可以换成具体的地址串,也能换成后台的地址串，因为我的是章节树所以我和章节id进行了关联

getTreeselect() \{  
treeselect().then((response) => \{  
//封面  
var img = '';  
this.ChapterOptions = response.data;  
for (let i = 0; i <this.ChapterOptions.length ; i++) \{  
this.videoName = this.ChapterOptions\[0\].children\[0\].chapterName  
this.videoIntroduce = this.ChapterOptions\[0\].children\[0\].chapterIntroduce  
this.VideoUrl = JSON.parse(this.ChapterOptions\[0\].children\[0\].videoAddress)  
img = JSON.parse(this.ChapterOptions\[0\].children\[0\].imageAddress)  
//初始化封面  
for (let j = 0; j <img.length ; j++) \{  
this.playerOptions.poster =img\[0\];  
\}

\})

\});  
\},

return data.label.indexOf(value) !== -1;

this.videoName = data.chapterName;  
//章节id  
this.learningDuration.chapterId = data.id  
// console.log(this.videoIntroduce)  
\},  
4.进度保存

接下来就是 保存视频的进度条了，通过打印发现onPlayerTimeupdate可获取到视频的进度，故采用定时器 每3秒触发一次数据交互

computed: \{  
player() \{  
return this.$refs.videoPlayer.player//自定义播放  
\}  
\},  
mounted () \{  
this.timer = setInterval(this.putLearningObj, 3000)  
\},  
destroyed () \{  
// 如果定时器在运行则关闭  
if (this.timer) \{  
clearInterval(this.timer)  
\}  
\},  
methods: \{  
putLearningObj () \{  
if (!this.paused) \{  
//保存视频进度  
saveTime(this.learningDuration)  
console.log('putLearningObj ~~~~~~~~~')  
\}  
\},  
//当前播放位置发生变化时触发。  
onPlayerTimeupdate (player) \{  
this.learningDuration.timeLog = player.cache\_.currentTime  
// console.log(' onPlayerTimeupdate!', this.timeLog)  
\},  
\},  
saveTime是我自定义的与后端交互的方法。（可自行定义）

1  
2  
3  
4  
5  
6  
7  
8  
// 保存视频进度  
export function saveTime(data) \{  
return request(\{  
url: '/\*\*\*/\*\*\*\*/\*\*\*/',  
method: 'put',  
data: data  
\})  
\}  
那么到了这一步 进度就能保存下来了

4.进度恢复

想要恢复进度，就必须在视频播放前把 保存进度下来的设置到视频当中，通过打印可以看出playerReadied 可以设置

3  
4  
5  
6  
/\* 设置视频进度 \*/  
playerReadied: function (player) \{  
//可在此调用后台交互方法  
...  
player.currentTime(this.learningDuration.timeLog)  
\},  
到此 进度可以 恢复了 大功告成！。至于后台交互数据 需求不一样，代码也就没有贴出来。
