做营销型网站价格网站外部优化的4大重点
一、登录海康开放平台下载web开发包，下载需要先登录海康账号，没有的需先注册一个。
这里的appkey、ip、port、secret 和cameraIndexCodeasd是自己去申请的
appkey: "****", ip: "****", port: **, secret: "****", //必填},cameraIndexCodeasd: "***", //必填 摄相机的code``
海康开放平台web开发包下载地址：开发包下载地址点击下载即可
二、打开bin文件夹下的VideoWebPlugin.exe点击安装完成
三、将web开发包引入vue项目
demo下的js文件
放到public中即可
<script src="./jquery-1.12.4.min.js"></script>
<script src="./web-control_1.2.5.min.js"></script>
<script src="./jsencrypt.min.js"></script>
四、template内容和data
<template><div><div id="playWnd" class="playWnd" /></div>
</template>
<script>
// 声明公用变量
var oWebControl = null;
var initCount = 0;
var pubKey = "";
export default {/*** index :当前组件所属页面 设备管理 为空 ||实时监控 realTime* type : 回放 || 直播* code : 监控点编号 监控设备页面String || 实时监控 Array* time 回放时间 暂时废弃*/props: ["mode", "code"],data() {return {swfWidth: 1920, //宽度swfHeight: 1080, //高度playText: "",objData: {appkey: "****", //必填ip: "****", //必填port: **, //必填443是默认secret: "****", //必填},cameraIndexCodeasd: "***8", //必填 摄相机的codeA线挂牌机器人入口};},}
</script>
五、在methods中创建WebControl实例
initPlugin() {var that = this;oWebControl = new WebControl({szPluginContainer: "playWnd",iServicePortStart: 15900,iServicePortEnd: 15900,szClassId: "23BF3B0A-2C56-4D97-9C03-0CB103AA8F11", // 用于IE10使用ActiveX的clsidcbConnectSuccess() {console.log("创建WebControl实例成功");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(() => {// // 启动插件服务成功oWebControl.JS_SetWindowControlCallback({// 设置消息回调cbIntegrationCallBack: that.cbIntegrationCallBack,});oWebControl.JS_CreateWnd("playWnd", that.swfWidth, that.swfHeight).then(() => {//JS_CreateWnd创建视频播放窗口，宽高可设定// oWebControl.JS_SetDocOffset({// left: 250,// top: 125,// }); // 更新插件窗口位置oWebControl.JS_Resize(that.swfWidth, that.swfHeight);setTimeout(() => {that.initBtnClicked(); // 创建播放实例成功后初始化}, 1000);});},() => {// 启动插件服务失败}).catch((err) => {console.log(err);});},cbConnectError: function () {var that = this;// 创建WebControl实例失败oWebControl = null;that.$message.warning("插件未启动，正在尝试启动，请稍候...");that.playText = "插件未启动，正在尝试启动，请稍候...";window.WebControl.JS_WakeUp("VideoWebPlugin://"); // 程序未启动时执行error函数，采用wakeup来启动程序initCount++;if (initCount < 3) {setTimeout(function () {that.initPlugin();}, 3000);} else {that.$message.warning("插件启动失败，请检查插件是否安装！");// console.log(initCount)that.playText = "插件启动失败，请检查插件是否安装！";if (initCount == 3) {that.frontDownload();//未安装安装包执行下载安装}}},cbConnectClose: () => {var that = this;// 创建WebControl实例失败oWebControl = null;that.$message.warning("插件未启动，正在尝试启动，请稍候...");that.playText = "插件未启动，正在尝试启动，请稍候...";window.WebControl.JS_WakeUp("VideoWebPlugin://"); // 程序未启动时执行error函数，采用wakeup来启动程序initCount++;if (initCount < 3) {setTimeout(function () {that.initPlugin();}, 3000);} else {that.$message.warning("插件启动失败，请检查插件是否安装！");// console.log(initCount)that.playText = "插件启动失败，请检查插件是否安装！";if (initCount == 3) {that.frontDownload();}}},});},
六、如果未安装提示安装下载
// 下载插件frontDownload() {var a = document.createElement("a"); // 创建一个<a></a>标签var peizhiurl = this.changeIp;a.href = peizhiurl + "/VideoWebPlugin.exe"; // 给a标签的href属性值加上地址，注意，这里是绝对路径，不用加 点.a.download = "VideoWebPlugin.exe"; // 设置下载文件文件名，这里加上.xlsx指定文件类型，pdf文件就指定.fpd即可a.style.display = "none"; // 障眼法藏起来a标签document.body.appendChild(a); // 将a标签追加到文档对象中a.click(); // 模拟点击了a标签，会触发a标签的href的读取，浏览器就会自动下载了a.remove(); // 一次性的，用完就删除a标签},
七、初始化
// 初始化requestInterface(value) {oWebControl.JS_RequestInterface(JSON.parse(value)).then(function (oData) {// console.log(oData);// this.showCBInfo(JSON.stringify(oData ? oData.responseMsg : ""));});},startPreview(cameraCode) {console.log("cameraCode", cameraCode);// 点击查询后显示oWebControl.JS_ShowWnd();var cameraIndexCode = "0e3c3db37ff042f58b4b87e12d08f812"; // 获取输入的监控点编号值，必填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）cameraIndexCode = cameraIndexCode.replace(/(^\s*)/g, "");oWebControl.JS_RequestInterface({funcName: "startPreview",argument: JSON.stringify({cameraIndexCode: 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}),});},// 获取公钥getPubKey(callback) {oWebControl.JS_RequestInterface({funcName: "getRSAPubKey",argument: JSON.stringify({keyLength: 1024,}),}).then(function (oData) {console.log(oData);if (oData.responseMsg.data) {pubKey = oData.responseMsg.data;callback();}});},// 设置窗口控制回调setCallbacks() {oWebControl.JS_SetWindowControlCallback({cbIntegrationCallBack: this.cbIntegrationCallBack(),});},// 推送消息// cbIntegrationCallBack(oData) {// showCBInfo(JSON.stringify(oData.responseMsg));// },// RSA加密setEncrypt(value) {var encrypt = new JSEncrypt();encrypt.setPublicKey(pubKey);return encrypt.encrypt(value);},// 显示接口返回的消息及插件回调信息showCBInfo(szInfo, type) {if (type === "error") {szInfo ="<div style='color: red;'>" +dateFormat(new Date(), "yyyy-MM-dd hh:mm:ss") +" " +szInfo +"</div>";} else {szInfo ="<div>" +dateFormat(new Date(), "yyyy-MM-dd hh:mm:ss") +" " +szInfo +"</div>";}$("#cbInfo").html(szInfo + $("#cbInfo").html());},initBtnClicked() {var that = this;var appkey = this.objData.appkey; // 综合安防管理平台提供的appkey，必填var secret = this.objData.secret; // 综合安防管理平台提供的secret，必填var ip = this.objData.ip; //综合安防管理平台IP地址，必填var playMode = 0; //初始播放模式：0-预览，1-回放var port = this.objData.port; //综合安防管理平台端口，若启用HTTPS协议，默认443var snapDir = ""; //抓图存储路径var videoDir = ""; //紧急录像或录像剪辑存储路径var layout = "1x1"; //playMode指定模式的布局var enableHTTPS = 1; //是否启用HTTPS协议与综合安防管理平台交互，这里总是填1// var encryptedFields = "secret"; //加密字段，默认加密领域为secretvar showToolbar = 0; //是否显示工具栏，0-不显示，非0-显示var showSmart = 0; //是否显示智能信息（如配置移动侦测后画面上的线框），0-不显示，非0-显示var buttonIDs = ""; //自定义工具条按钮var params = {argument: {appkey: appkey, //API网关提供的appkeysecret: secret, //API网关提供的secretip: ip, //API网关IP地址playMode: playMode, //播放模式（决定显示预览还是回放界面）port: port, //端口snapDir: snapDir, //抓图存储路径videoDir: videoDir, //紧急录像或录像剪辑存储路径layout: layout, //布局enableHTTPS: enableHTTPS, //是否启用HTTPS协议// encryptedFields: encryptedFields, //加密字段showToolbar: showToolbar, //是否显示工具栏showSmart: showSmart, //是否显示智能信息buttonIDs: buttonIDs, //自定义工具条按钮},funcName: "init",};var param = JSON.stringify(params);// console.log(params);//删除字符串中的回车换行param = param.replace(/(\s*)/g, "");// 执行初始化this.requestInterface(param);this.playFn();},playFn() {var cameraIndexCode = this.cameraIndexCodeasd;(""); //获取输入的监控点编号值，必填var streamMode = 0; //主子码流标识：0-主码流，1-子码流var transMode = 1; //传输协议：0-UDP，1-TCPvar gpuMode = 0; //是否启用GPU硬解，0-不启用，1-启用var wndId = -1; //播放窗口序号（在2x2以上布局下可指定播放窗口）cameraIndexCode = cameraIndexCode.replace(/(^\s*)/g, "");cameraIndexCode = cameraIndexCode.replace(/(\s*$)/g, "");var params = {argument: {cameraIndexCode: 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},funcName: "startPreview",};var param = JSON.stringify(params);// console.log(param);//删除字符串中的回车换行param = param.replace(/(\s*)/g, "");// 执行预览this.requestInterface(param);},// 插件窗口销毁destoryWnd() {if (oWebControl != null) {oWebControl.JS_HideWnd(); // 先让窗口隐藏，规避可能的插件窗口滞后于浏览器消失问题oWebControl.JS_RequestInterface({funcName: "destroyWnd",}); // 销毁当前播放的视频oWebControl.JS_Disconnect(); // 断开与插件服务连接}},SetDocOffset() {if (oWebControl != null) {oWebControl.JS_Resize(this.swfWidth, this.swfHeight);}},// 格式化时间dateFormat(oDate, fmt) {var o = {"M+": oDate.getMonth() + 1, //月份"d+": oDate.getDate(), //日"h+": oDate.getHours(), //小时"m+": oDate.getMinutes(), //分"s+": oDate.getSeconds(), //秒"q+": Math.floor((oDate.getMonth() + 3) / 3), //季度S: oDate.getMilliseconds(), //毫秒};if (/(y+)/.test(fmt)) {fmt = fmt.replace(RegExp.$1,(oDate.getFullYear() + "").substr(4 - RegExp.$1.length));}for (var k in o) {if (new RegExp("(" + k + ")").test(fmt)) {fmt = fmt.replace(RegExp.$1,RegExp.$1.length == 1? o[k]: ("00" + o[k]).substr(("" + o[k]).length));}}return fmt;},
八、挂载和销毁
mounted() {this.initPlugin(); // 初始化video界面window.addEventListener("resize", this.SetDocOffset);},destroyed() {// 组件销毁后this.destoryWnd();window.removeEventListener("resize", this.SetDocOffset);},beforeDestroy() {this.destoryWnd();},
九、最终实现
十、一些规格参数
initBtnClicked方法中有配置性文件
var playMode = 0; //初始播放模式：0-预览，1-回放var port = this.objData.port; //综合安防管理平台端口，若启用HTTPS协议，默认443var snapDir = ""; //抓图存储路径var 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1// var encryptedFields = "secret"; //加密字段，默认加密领域为secretvar showToolbar = 0; //是否显示工具栏，0-不显示，非0-显示var showSmart = 0; //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
十一、最终vue页面代码
<template><div><div id="playWnd" class="playWnd" /></div>
</template><script>
// 声明公用变量
var oWebControl = null;
var initCount = 0;
