一、需求

需要在浏览器点击查看海康的监控视频

二、最后成果展示

插件下载地址：https://download.csdn.net/download/xm_w_xm/87995593

三、思路和方法

3.1 首先安装插件，可以在上面的地址中下载安装，建立一个dom

<div id="playWnd" class="playWnd"></div>

3.2 初始化的时候可以获取一个视频展示的一个长宽

 mounted() {this.clientWidth = document.body.clientWidth * (7 / 10);this.clientHeight = document.body.clientHeight * (7 / 10);},

3.3 vue data中定义

data() {return {initCount: 0,pubKey: "",oWebControl: null,cameraIndexCode: "",title: "",clientWidth: 1000,clientHeight: 800,downloadUrl: `${process.env.VUE_APP_IMG_API}/js/video/VideoWebPlugin.exe`,};},

3.4 初始化视频的方法在vue的methods中

initPlugin(val) {let that = this;if (val) {that.cameraIndexCode = val.cameraIndex;this.title = val.name;that.oWebControl = new WebControl({szPluginContainer: "playWnd", // 指定容器idiServicePortStart: 15900, // 指定起止端口号，建议使用该值iServicePortEnd: 15900,szClassId: "用于IE10使用ActiveX的clsid", // 用于IE10使用ActiveX的clsidcbConnectSuccess: function () {// 创建WebControl实例成功that.oWebControl.JS_StartService("window", {// WebControl实例创建成功后需要启动服务dllPath: "./VideoPluginConnect.dll", // 值"./VideoPluginConnect.dll"写死}).then(function () {// 启动插件服务成功that.oWebControl.JS_CreateWnd("playWnd",that.clientWidth,that.clientHeight).then(function () {//JS_CreateWnd创建视频播放窗口，宽高可设定that.init(); // 创建播放实例成功后初始化setTimeout(() => {that.startPreview();}, 2500);});},function () {// 启动插件服务失败});},cbConnectError: function () {// 创建WebControl实例失败that.oWebControl = null;$("#playWnd").html("插件未启动，正在尝试启动，请到这个地址下载并安装：" +that.downloadUrl);WebControl.JS_WakeUp("VideoWebPlugin://"); // 程序未启动时执行error函数，采用wakeup来启动程序that.initCount++;if (that.initCount < 3) {setTimeout(function () {// that.initPlugin();}, 3000);} else {$("#playWnd").html("插件启动失败，请检查插件是否安装！");}},cbConnectClose: function (bNormalClose) {// 异常断开：bNormalClose = false// JS_Disconnect正常断开：bNormalClose = trueconsole.log("cbConnectClose");that.oWebControl = null;$("#playWnd").html("插件未启动，正在尝试启动，请到这个地址下载并安装：" +that.downloadUrl);WebControl.JS_WakeUp("VideoWebPlugin://");that.initCount++;if (that.initCount < 3) {setTimeout(function () {// that.initPlugin();}, 3000);} else {$("#playWnd").html("插件启动失败，请检查插件是否安装！");}},});}},getPubKey(callback) {let that = this;that.oWebControl.JS_RequestInterface({funcName: "getRSAPubKey",argument: JSON.stringify({keyLength: 1024,}),}).then(function (oData) {// console.log(oData);if (oData.responseMsg.data) {that.pubKey = oData.responseMsg.data;callback();}});},setEncrypt(value) {var encrypt = new JSEncrypt();encrypt.setPublicKey(this.pubKey);return encrypt.encrypt(value);},init() {let that = this;that.getPubKey(function () {var appkey = "综合安防管理平台提供的appkey"; //综合安防管理平台提供的appkey，必填var secret = that.setEncrypt("综合安防管理平台提供的secret，必填"); //综合安防管理平台提供的secret，必填var ip = "综合安防管理平台IP地址，必填"; //综合安防管理平台IP地址，必填var playMode = 0; //初始播放模式：0-预览，1-回放var port = 443; //综合安防管理平台端口，若启用HTTPS协议，默认443var snapDir = "D:\\SnapDir"; //抓图存储路径var videoDir = "D:\\VideoDir"; //紧急录像或录像剪辑存储路径var layout = "1x1"; //playMode指定模式的布局var enableHTTPS = 1; //是否启用HTTPS协议与综合安防管理平台交互，这里总是填1var encryptedFields = "secret"; //加密字段，默认加密领域为secretvar showToolbar = 1; //是否显示工具栏，0-不显示，非0-显示var showSmart = 1; //是否显示智能信息（如配置移动侦测后画面上的线框），0-不显示，非0-显示var buttonIDs ="0,16,256,257,258,259,260,512,513,514,515,516,517,768,769"; //自定义工具条按钮that.oWebControl.JS_RequestInterface({funcName: "init",argument: JSON.stringify({appkey: appkey, //API网关提供的appkeysecret: secret, //API网关提供的secretip: ip, //API网关IP地址playMode: playMode, //播放模式（决定显示预览还是回放界面）port: port, //端口snapDir: snapDir, //抓图存储路径videoDir: videoDir, //紧急录像或录像剪辑存储路径layout: layout, //布局enableHTTPS: enableHTTPS, //是否启用HTTPS协议encryptedFields: encryptedFields, //加密字段showToolbar: showToolbar, //是否显示工具栏showSmart: showSmart, //是否显示智能信息buttonIDs: buttonIDs, //自定义工具条按钮}),}).then(function (oData) {that.oWebControl.JS_Resize(that.clientWidth, that.clientHeight); // 初始化后resize一次，规避firefox下首次显示窗口后插件窗口未与DIV窗口重合问题});});},

3.5 开始方法

// 点击开始startPreview() {var streamMode = 0; //主子码流标识：0-主码流，1-子码流var transMode = 1; //传输协议：0-UDP，1-TCPvar gpuMode = 0; //是否启用GPU硬解，0-不启用，1-启用var wndId = -1; //播放窗口序号（在2x2以上布局下可指定播放窗口）this.oWebControl.JS_RequestInterface({funcName: "startPreview",argument: JSON.stringify({cameraIndexCode: this.cameraIndexCode, //监控点编号streamMode: streamMode, //主子码流标识transMode: transMode, //传输协议gpuMode: gpuMode, //是否开启GPU硬解wndId: wndId, //可指定播放窗口}),});},

3.6 暂停方法

// 停止stopAllPreview() {this.oWebControl.JS_RequestInterface({funcName: "stopAllPreview",});},

3.7 销毁监控方法

closeAllPreview() {if (this.oWebControl) {this.stopAllPreview();this.oWebControl.JS_HideWnd();this.oWebControl.JS_DestroyWnd({funcName: "destroyeWnd",}).then(function () {});}this.oWebControl = null;},closeVideo() {this.closeAllPreview();},
