需求:

1.一次只能播放一个视频。

2.播放页面禁止刷新。

3.打开视频若该视频之前已经学习过一段时间,则再次打开可以跳至上次播放的位置继续播放。

4.视频每隔5秒进行一次打点调后端接口,记录当前学习时间,视频暂停、报错则清除定时器

5.只有测评师学习时才进行打点,并且不能拖拽大约15秒的时间。

如何调用阿里播放器?

1.在index.html中引入:

    <link rel="stylesheet" href="https://g.alicdn.com/de/prismplayer/2.8.2/skins/default/aliplayer-min.css" />
    <script charset="utf-8" type="text/javascript" src="https://g.alicdn.com/de/prismplayer/2.8.2/aliplayer-min.js"></script>

2.开始调用;

创建调用播放器的dom

                <div class="video-tem">
                    <div id="J_prismPlayer" class="prism-player"></div>
                </div>

在需要播放器的页面中   mounted方法里初始化播放器;

            this.ideovSource = this.ideovUrl + this.$route.params.fileId + "/output.m3u8"
            // 初始化播放器
            const that = this
            this.player = new Aliplayer({
                id: "J_prismPlayer", // 容器id
                source: this.ideovSource,//视频地址
                // cover: "http://cdn.img.mtedu.com/images/assignment/day_3.jpg",  //播放器封面图
                autoplay: true,      // 是否自动播放
                width: "100%",       // 播放器宽度
                height: "610px",      // 播放器高度
                playsinline: true,
                "skinLayout": [
                    {
                        "name": "bigPlayButton",
                        "align": "blabs",
                        "x": 500,
                        "y": 300
                    },
                    {
                        "name": "H5Loading",
                        "align": "cc"
                    },
                    {
                        "name": "errorDisplay",

                    },
                    {
                        "name": "infoDisplay"
                    },
                    {

                        "name": "thumbnail"
                    },
                    {
                        "name": "controlBar",
                        "align": "blabs",
                        "x": 0,
                        "y": 0,
                        "children": [
                            {
                                "name": "progress",
                                "align": "blabs",
                                "x": 0,
                                "y": 44
                            },
                            {
                                "name": "playButton",
                                "align": "tl",
                                "x": 15,
                                "y": 12
                            },
                            {
                                "name": "timeDisplay",
                                "align": "tl",
                                "x": 10,
                                "y": 7
                            },
                            {
                                "name": "fullScreenButton",
                                "align": "tr",
                                "x": 10,
                                "y": 12
                            },
                            {
                                "name": "volume",
                                "align": "tr",
                                "x": 5,
                                "y": 10
                            }
                        ]
                    }
                ]
            })

效果图:

默认是播放状态

如果想更改视频中按钮的样式,可以参考:在线配置

然后根据你的需求更改 皮肤自定义。

3.添加播放视频限制:

只有从列表页跳转过来的,才会带播放视频参数,如果没有则提示(要么在视频播放页点击刷新按钮;要么复制视频链接新开页面粘贴到地址栏)

在初始化播放器前加以下代码:

            //是否出发拖拽事件
            this.haveSeek = false
            // 先判断是否是复制的 url 进入到播放页面
            if (!this.$route.params.Ids && !this.$route.params.fileId) {
                this.$message({
                    message: ‘暂未获取到视频信息,请从列表页重新打开‘,
                    type: ‘warning‘
                });
                return
            }

4.添加已经播放视频标识:

在初始化播放器后加以下代码:

            that.currentTime = new Date().getTime()
            if (localStorage.getItem(‘havePlay‘) && JSON.parse(localStorage.getItem(‘havePlay‘)).playerId !== that.$route.params.fileId) {
                that.player.pause()
                that.$message({
                    message: ‘您已经有正在播放的视屏,不能同时播放多个!‘,
                    type: ‘warning‘
                });
            } else if (!localStorage.getItem(‘havePlay‘)) {
                const obj = {
                    playerId: that.$route.params.fileId,
                    havePlay: true,
                    currentTime: that.currentTime
                }
                localStorage.setItem(‘havePlay‘, JSON.stringify(obj))
            }

5.处理播放器拖拽事件、播放事件、销毁事件(记录是否拖拽,获取拖拽时间,用于判断视频是否被拖拽大于15秒)

在上面代码下继续追加以下代码:

            //视频由暂停恢复为播放时触发。
            that.player.on(‘completeSeek‘, function ({paramData}) {
                that.haveSeek = true
                that.playTime = paramData;
            })
            //视频由暂停恢复为播放时触发。
            that.player.on(‘playing‘, function (e) {
                that.playTime = that.player.getCurrentTime();
            })
            //视频销毁。
            that.player.on(‘dispose‘, function (e) {
                if (JSON.parse(localStorage.getItem(‘havePlay‘))) {
                    window.localStorage.removeItem("havePlay");
                }
                that.clearIntervalFun();
            })

6.监听播放时间:playTime

        watch: {
            playTime(val, oldVal) {
                //获取拖拽时间,大于5秒则不进行打点
                const that = this
                if ((that.haveSeek && that.record.type !== 2) && (val - oldVal > 15) && that.isEvaluator.length !== 0) {
                    that.clearIntervalFun();
                    that.$message({
                        message: ‘拖拽时间不能大于15秒‘,
                        type: ‘warning‘
                    });
                }
            }
        },

7.视频滚动到上次播放时间的位置

在获取视频详情方法中:methods——>

播放器的play 方法中满足一定条件,调定时事件:recordFun 方法。

播放器的 canplaythrough 方法中,滚动到上次播放时间的位置。

            getDetailsAct(id) {
                const that = this
                that.$store.dispatch("CPE/detailsAct", id).then((response) => {
                    if (response.code === 200) {
                        that.detailsDt = that.$store.state.CPE.detailsDt
                        that.record = that.$store.state.CPE.detailsDt
                        that.record.courseId = that.detailsDt.rootId//课程id
                        that.record.coursewareId = that.detailsDt.id//课件id
                        that.ideovSource = that.ideovUrl + that.detailsDt.resourceFileId + "/output.m3u8"
                        that.player.loadByUrl(that.ideovSource)
                        var seeked = false;
                        that.player.on(‘play‘, function (e) {
                            if (localStorage.getItem(‘havePlay‘) && JSON.parse(localStorage.getItem(‘havePlay‘)).playerId !== that.$route.params.fileId) {
                                that.player.pause()
                                that.$message({
                                    message: ‘您已经有正在播放的视屏,不能同时播放多个!‘,
                                    type: ‘warning‘
                                });
                            }
                            if (that.userInfo.roleList.length !== 0) {
                                that.isEvaluator = that.userInfo.roleList.filter(function (item) {
                                    //用户角色集合,2-等保测评师,3-内容管理员,4-联盟管理员,5-普通用户,6-讲师
                                    if (item == 2) {
                                        return item
                                    }
                                })
                            }
                            //只有是测评师并且没有学习完时才进行打点
                            if ((localStorage.getItem(‘havePlay‘) && JSON.parse(localStorage.getItem(‘havePlay‘)).playerId === that.$route.params.fileId) && (that.record.type !== 2 && that.isEvaluator.length !== 0)) {
                                that.recordFun()
                            }
                        });
                        that.player.on(‘canplaythrough‘, function (e) {
                            if (!seeked) {
                                seeked = true;
                                if (that.record.type === 1) {
                                    that.playTime = that.detailsDt.schedule
                                    that.player.seek(Number(that.detailsDt.schedule));//设置播放到我上次播放的位置
                                }
                            }
                        });
                    }
                }).catch(() => {
                })
            },

8.定时器事件

            recordFun() {
                const that = this
                that.intervalTime = setInterval(function () {
                    if (that.record.type !== 2 && that.isEvaluator.length !== 0) {
                        var currentTime = that.player.getCurrentTime();
                        that.record.schedule = currentTime
                        //1:学习中,2:学习完成
                        that.record.type = 1
                        that.$store.dispatch("CPE/recordAct", that.record)
                    }else {
                        that.clearIntervalFun();
                    }
                }, 5000);
                this.player.on(‘ended‘, function (e) {
                    window.localStorage.removeItem("havePlay");
                    that.record.schedule = that.record.resourceSize
                    //1:学习中,2:学习完成
                    that.record.type = 2
                    that.$store.dispatch("CPE/recordAct", that.record)
                    that.clearIntervalFun();
                });
                this.player.on(‘pause‘,function  (e) {
                    that.clearIntervalFun();
                });
                this.player.on(‘error‘,function  (e) {
                    that.clearIntervalFun();
                    window.localStorage.removeItem("havePlay");
                });
            },

9.清除定时器:

            //清除定时器
            clearIntervalFun() {
                const that = this
                if (that.intervalTime) {
                    clearInterval(that.intervalTime);
                    that.intervalTime = null;
                }
            },

10.阻止F5刷新事件,监听浏览器刷新事件

判断如果在正在播放的视频页面,按了刷新按钮,清除有视频播放标识

            //阻止F5刷新
            stopF5Refresh() {
                document.onkeydown = function (e) {
                    var evt = window.event || e;
                    var code = evt.keyCode || evt.which;
                    if (code == 116) {
                        if (evt.preventDefault) {
                            evt.preventDefault();
                        } else {
                            evt.keyCode = 0;
                            evt.returnValue = false
                        }
                    }
                }
            },
            //浏览器刷新事件
            beforeunloadHandler (e) {
                if (JSON.parse(localStorage.getItem(‘havePlay‘))&& JSON.parse(localStorage.getItem(‘havePlay‘)).currentTime == this.currentTime) {
                    window.localStorage.removeItem("havePlay");
                }
            },
