萤石云开发平台地址：文档概述 · 萤石开放平台API文档 (ys7.com)

萤石云监控播放

• 首先引入萤石云js

js地址：GitHub - Ezviz-OpenBiz/EZUIKit-JavaScript-npm: 轻应用npm版本，降低接入难度，适配自定义UI，适配主流框架

video.vue

<template>
	<view class="content">
		<view class="preview" id="video-container"></view>
		<view>
			<button @click="ezuikit.stop">stop</button>
			<button @click="ezuikit.play">play</button>
		</view>
	</view>
</template>

<script>
	export default {
		data() {
			return {
				strings: ' '
			}
		},
		methods: {
			
		}
	}
</script>

<script module="ezuikit" lang="renderjs">
	var player = null;

	export default {
	
		mounted() {
			console.log('mounted...');

			if (typeof window.EZUIKit !== 'undefined') {
				
				console.log('defined EZUIKit...');
				this.initPlayer();
			} else {
				
				console.log('undefined EZUIKit...');				
				// 动态引入较大类库避免影响页面展示
				const script = document.createElement('script')
				// view 层的页面运行在 www 根目录，其相对路径相对于 www 计算
				script.src = 'static/ezuikit.js'
				script.onload = this.initPlayer.bind(this)
				document.head.appendChild(script)
			}
		},

		methods: {
			initPlayer() {
				const {
					windowWidth,
					windowHeight
				} = uni.getSystemInfoSync();
				console.log('initPlayer...');
						
				fetch('https://open.ys7.com/jssdk/ezopen/demo/token')
				      .then(response => response.json())
				      .then(res => {
				        var accessToken = res.data.accessToken;
				        player = new EZUIKit.EZUIKitPlayer({
				          id: 'video-container', // 视频容器ID
				          accessToken: accessToken,

				      });
			},
			play() {
				var playPromise = player.play();
				playPromise.then((data) => {
					console.log("promise 获取 数据", data)
				})
			},
			stop() {
				var stopPromise = player.stop();
				stopPromise.then((data) => {
					console.log("promise 获取 数据", data)
				})
			}
		}
	}
</script>

<style>
	.content {
		display: flex;
		flex-direction: column;
		align-items: center;
		justify-content: center;
	}

	.preview {
		background-color: black;
	}
</style>

云台控制

player = new EZUIKit.EZUIKitPlayer({
					id: 'ezuikit', // 视频容器ID
					accessToken: this.ezuikitDataM.accessToken,
					url: 'ezopen://open.ys7.com/' + this.ezuikitDataM.deviceSerial + '/'+this.ezuikitDataM.channelNo+'.live',

					template: 'mobileLive',
					plugin: ['talk', 'ptz'], // 加载插件，talk-对讲
					width: windowWidth,
					height: windowWidth * 2 / 3,
				});

截图

使用接口：https://open.ys7.com/api/lapp/device/capture   -   设备抓拍图片

接口文档位置：文档概述 · 萤石开放平台API文档 (ys7.com)

screenshot() {
				this.isLoading = true
				let _this = this
				post('/api/lapp/device/capture', {
					'accessToken': this.ezuikitData.accessToken,
					'deviceSerial': this.ezuikitData.deviceSerial,
					'channelNo': this.newData.channelNo,
					'quality': 1
				}, {
					'content-type': 'application/x-www-form-urlencoded'
				}, 'https://open.ys7.com').then(res => {
					uni.saveImageToPhotosAlbum({
						filePath: res.data.data.picUrl,
						success: function(res2) {
							_this.isLoading = false
							_this.$refs.messagePopup.showMessage('success', '圖片保存成功')
						},
						fail: function(err2) {

						}
					});

				}).catch(err => {
					console.error(err);
				});
			}

录像

• 首先要创建一个存储项目，拿到项目ID后再录制

• 录制视频到云端项目存储

即时视频转码录制存储接口，接口：https://open.ys7.com/api/open/cloud/v1/instant/record/save

接口描述：立即开始进行视频录制

预约视频转码录制存储接口，接口：https://open.ys7.com/api/open/cloud/v1/preview/save

接口描述： 从实时视频中取流进行转码录制，注意该接口开始时间需在未来 10 分钟后

文档地址：文档概述 · 萤石开放平台API文档 (ys7.com)

//即时录制
recordSave() {
				let _this = this
				post('/api/open/cloud/v1/instant/record/save', {
					'projectId': 'YtechAppRecord',
					'recordSeconds': '15'
				}, {
					'accessToken': this.ezuikitData.accessToken,
					'deviceSerial': this.ezuikitData.deviceSerial,
					'localIndex': this.ezuikitData.channelNo,
					'content-type': 'application/x-www-form-urlencoded'
				}, 'https://open.ys7.com').then(res => {
					_this.taskId = res.data.data.taskId
				}).catch(err => {
					console.error(err);
				});
			}

• 根据任务ID查询视频文件，并获取下载链接

接口：https://open.ys7.com/api/v3/open/cloud/task/files

文档：https://open.ys7.com/api/v3/open/cloud/task/files

taskFiles() {
				let _this = this
				get('/api/v3/open/cloud/task/files', {
					'accessToken': _this.ezuikitData.accessToken,
					'taskId': _this.taskId,
					'hasUrl': true
				}, {
					'content-type': 'application/x-www-form-urlencoded'
				}, 'https://open.ys7.com').then(res => {
					uni.downloadFile({
						url: res.data.data[0].downloadUrls[0],
						success: (downloadResult) => {
							if (downloadResult.statusCode === 200) {
								uni.saveVideoToPhotosAlbum({
									filePath: downloadResult.tempFilePath,
									success: () => {
										_this.$refs.messagePopup.showMessage('default', '保存到相冊成功')
									},
									fail: (err) => {
										console.log(err)
									}
								});
							}
						},
						fail: (err) => {
							console.log(err)
						}
					})
				}).catch(err => {
					console.error(err);
				});
			}

历史映像

player = new EZUIKit.EZUIKitPlayer({
					id: 'ezuikit', // 视频容器ID
					accessToken: this.ezuikitDataM.accessToken,
					url: 'ezopen://open.ys7.com/' + this.ezuikitDataM.deviceSerial + '/'+this.ezuikitDataM.channelNo+'.live',
					// simple - 极简版; pcLive-pc直播；pcRec-pc回放；mobileLive-移动端直播；mobileRec-移动端回放;security - 安防版;voice-语音版;
					template: 'mobileRec',
					width: windowWidth,
					height: windowWidth * 2 / 3
				});

<script module="ezuikit" lang="renderjs">

• renderjs的概念

运行在视图层的js，只支持app-vue和h5（简单来说就是开了另外一条线程）

• renderjs的作用

大幅降低逻辑层和视图层的通讯损耗，提供高性能视图交互能力（减少通讯损耗提升性能，例如一些手势或canvas动画的场景）

在视图层操作dom，运行for web的js库（可以操作dom，意味着拥有window、document等这些全局变量，在app-vue的service层没有这些）

•  renderjs的使用

在原先的script标签的同级新增一个script，设置lang=renderjs，module=(值任意，相当于命名空间，之后会根据这个名字调用其中的方法)

renderjs和service层的通信示例一

<template>
	<view class="content">
		<!-- #ifdef APP-PLUS || H5 -->
		<view @click="echarts.onClick" :prop="option" :change:prop="echarts.updateEcharts" id="echarts" class="echarts"></view>
		<button @click="changeOption">更新数据</button>
		<!-- #endif -->
		<!-- #ifndef APP-PLUS || H5 -->
		<view>非 APP、H5 环境不支持</view>
		<!-- #endif -->
	</view>
</template>

<script>
	export default {
		data() {
			return {
				option: {
					title: {
						text: 'ECharts 入门示例'
					},
					tooltip: {},
					legend: {
						data: ['销量']
					},
					xAxis: {
						data: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"]
					},
					yAxis: {},
					series: [{
						name: '销量',
						type: 'bar',
						data: [5, 20, 36, 10, 10, 20]
					}]
				}
			}
		},
		onLoad() {

		},
		methods: {
			changeOption() {
				const data = this.option.series[0].data
				// 随机更新示例数据
				data.forEach((item, index) => {
					data.splice(index, 1, Math.random() * 40)
				})
			},
			onViewClick(options) {
				console.log(options)
			}
		}
	}
</script>

<script module="echarts" lang="renderjs">
	let myChart
	export default {
		mounted() {
			if (typeof window.echarts === 'function') {
				this.initEcharts()
			} else {
				// 动态引入较大类库避免影响页面展示
				const script = document.createElement('script')
				// view 层的页面运行在 www 根目录，其相对路径相对于 www 计算
				script.src = 'static/echarts.js'
				script.onload = this.initEcharts.bind(this)
				document.head.appendChild(script)
			}
		},
		methods: {
			initEcharts() {
				myChart = echarts.init(document.getElementById('echarts'))
				// 观测更新的数据在 view 层可以直接访问到
				myChart.setOption(this.option)
			},
			updateEcharts(newValue, oldValue, ownerInstance, instance) {
				// 监听 service 层数据变更
				myChart.setOption(newValue)
			},
			onClick(event, ownerInstance) {
				// 调用 service 层的方法
				ownerInstance.callMethod('onViewClick', {
					test: 'test'
				})
			}
		}
	}
</script>

<style>
	.content {

	.echarts {
