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

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

:props="defaultProps"

node-key='id'

highlight-current

:filter-node-method="filterNode"

ref="tree"

default-expand-all

@node-click="handleNodeClick" />

class="video-player vjs-custom-skin"

style="width: 1000px;height: 576px;display: inline-flex"

:playsinline="true"

:options="playerOptions"

@pause="onPlayerPause($event)"

@ended="onPlayerEnded($event)"

@play="onPlayerPlay($event)"

@timeupdate="onPlayerTimeupdate($event)"

@ready="playerReadied"

/>

import { videoPlayer } from 'vue-video-player'

import 'video.js/dist/video-js.css'

import 'vue-video-player/src/custom-theme.css'

import { treeselect } from "@/api//driver/videoChapter";

import Treeselect from "@riophae/vue-treeselect";

import "@riophae/vue-treeselect/dist/vue-treeselect.css";

export default {

name: "videoPlayer",

components: { Treeselect,videoPlayer },

data() {

return {

//用户信息

user:{},

//===============================

paused: true,

learningDuration: {

userId: '', //用户id

chapterId:'',//章节id

timeLog: '', //视频观看时长

},

playerOptions: {

playbackRates: [0.5, 1.0, 1.5, 2.0], //播放速度

aspectRatio: '16:9', // 将播放器置于流畅模式，并在计算播放器的动态大小时使用该值。值应该代表一个比例 - 用冒号分隔的两个数字(例如"16:9"或"4:3")

fluid: true, // 当true时，Video.js player将拥有流体大小。换句话说，它将按比例缩放以适应其容器。

controlBar: {

//当前时间和持续时间的分隔符

timeDivider: true,

//显示持续时间

durationDisplay: true,

//是否显示剩余时间功能

remainingTimeDisplay: false,

//全屏按钮

fullscreenToggle: true

}

}

};

},

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: {

//用户信息

getUser() {

getUserProfile().then(response => {

this.user = response.data;

this.learningDuration.userId = this.user.userId

});

},

//============================

fullScreen() {

const player = this.$refs.videoPlayer.player

player.requestFullscreen()//调用全屏api方法

player.isFullscreen(true)

player.play()

},

onPlayerPlay(player) {

this.paused = false

// player.play()

},

onPlayerPause (player) {

this.paused = true

// console.log('onPlayerPause!', player)

},

onPlayerEnded (player) {

this.paused = false;

// clearInterval(this.timer);

},

//当前播放位置发生变化时触发。

onPlayerTimeupdate (player) {

// console.log(' onPlayerTimeupdate!', this.timeLog)

},

/* 设置视频进度 */

playerReadied: function (player) {

},

};

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

/** 查询部门下拉树结构 */

getTreeselect() {

treeselect().then((response) => {

//封面

var img = '';

this.ChapterOptions = response.data;

for (let i = 0; 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

this.playerOptions.poster =img[0];

}

//初始化第一个章节视频

for (let j = 0; j

this.playerOptions.sources[0].src = this.VideoUrl[0]

}

//初始化章节

this.learningDuration.chapterId = this.ChapterOptions[0].children[0].id;

//默认高亮第一个章节节点

this.$nextTick(()=>{

this.$refs.tree.setCurrentKey(this.ChapterOptions[0].children[0].id);

})

}

});

},

// 筛选节点

filterNode(value, data) {

if (!value) return true;

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

},

// 节点单击事件

handleNodeClick(data) {

// console.log(data)

var img = '';

//刷新原视频, 原封面

this.playerOptions.sources[0].src = '';

this.playerOptions.poster = '';

//转换视频

this.VideoUrl= JSON.parse(data.videoAddress);

// console.log("this.VideoUrl")

for (let i = 0; i

this.playerOptions.sources[0].src = this.VideoUrl[0];

}

img = JSON.parse(data.imageAddress);

for (let i = 0; i

this.playerOptions.poster = img[0];

}

// console.log("this.playerOptions.sources[0].src")

// console.log(this.playerOptions.sources[0].src)

//章节介绍

this.videoIntroduce = data.chapterIntroduce;

//章节名称

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)

// 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

/* 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。
