插件使用步骤总结
1.new 一个WebControl 插件实例
2. 启动插件服务
3.创建视频播放窗口、绑定消息回调
4.初始化参数，其中secret参数需要通过RSA加密，加密公钥通过WebControl.JS_RequestInterface获取
5.通过WebControl 插件实例调用API方法操作功能（预览，回放，抓图、录像等）
6.离开页面断开与插件服务连接
具体步骤分析
1.new 一个WebControl 插件实例
后续功能都将通过该实例操作
// 插件对象实例，初始化为null，需要创建多个插件窗口时，需要定义多个插件对象实例变量，各个变量唯一标志对应的插件实例
let oWebControl = null;
// 创建插件实例，并启动本地服务建立websocket连接，创建插件窗口
function initPlugin () {oWebControl = new WebControl({szPluginContainer: "playWnd",iServicePortStart: 15900,iServicePortEnd: 15900,szClassId:"23BF3B0A-2C56-4D97-9C03-0CB103AA8F11", // 用于IE10使用ActiveX的clsidcbConnectSuccess: function () {initCount = 0;setCallbacks(); oWebControl.JS_StartService("window", {dllPath: "./VideoPluginConnect.dll"}).then(function () {oWebControl.JS_CreateWnd("playWnd", 800, 400).then(function () {console.log("JS_CreateWnd success");oWebControl.JS_RequestInterface({funcName: "getRSAPubKey",argument: JSON.stringify({keyLength: 1024})}).then(function (oData) {console.log(oData)if (oData.responseMsg.data) {pubKey = oData.responseMsg.data}}); });}, function () {});},cbConnectError: function () {console.log("cbConnectError");oWebControl = null;$("#playWnd").html("插件未启动，正在尝试启动，请稍候...");WebControl.JS_WakeUp("VideoWebPlugin://");initCount ++;if (initCount < 3) {setTimeout(function () {initPlugin();}, 3000)} else {$("#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");oWebControl = null;$("#playWnd").html("插件未启动，正在尝试启动，请稍候...");WebControl.JS_WakeUp("VideoWebPlugin://");initCount ++;if (initCount < 3) {setTimeout(function () {initPlugin();}, 3000)} else {$("#playWnd").html("插件启动失败，请检查插件是否安装！");} }});
}
initPlugin(); 2.启动插件服务
创建WebControl实例成功的回调函数中通过oWebControl.JS_StartService启动插件服务：
oWebControl.JS_StartService("window", {dllPath: "./VideoPluginConnect.dll"
}).then(function () {oWebControl.JS_CreateWnd("playWnd", 800, 400).then(function () {console.log("JS_CreateWnd success");oWebControl.JS_RequestInterface({funcName: "getRSAPubKey",argument: JSON.stringify({keyLength: 1024})}).then(function (oData) {console.log(oData)if (oData.responseMsg.data) {pubKey = oData.responseMsg.data}}); });
},3.创建视频播放窗口、绑定消息回调
通过创建播放窗口绘制样式布局，并绑定一些事件（进出全屏、切换布局消息等）的回调
setCallbacks();
// 设置窗口控制回调
function setCallbacks() {oWebControl.JS_SetWindowControlCallback({cbIntegrationCallBack: cbIntegrationCallBack});
}
// 推送消息
function cbIntegrationCallBack(oData) {showCBInfo(JSON.stringify(oData.responseMsg));
}
// 显示接口返回的消息及插件回调信息
function showCBInfo(szInfo, type) {console.log(szInfo, type);
}4.初始化参数，其中secret参数需要通过RSA加密，加密公钥通过WebControl.JS_RequestInterface获取
通过appkey、secret、ip、port端口号等参数与服务器进行数据校验，校验通过即可正常与设备链接取流，初始化参数在步骤三创建窗口成功回调后执行，其中secret参数必须通过RSA进行加密处理，加密的公钥通过WebControl.JS_RequestInterface获取
oWebControl.JS_CreateWnd("playWnd", 1000, 600).then(function () { //JS_CreateWnd创建视频播放窗口，宽高可设定init(); // 创建播放实例成功后初始化
});//初始化
function init() {getPubKey(function () {// 请自行修改以下变量值 var appkey = "20211111"; //综合安防管理平台提供的appkey，必填var secret = setEncrypt("Xxxxxxxxxxxxxxxxxx"); //综合安防管理平台提供的secret，必填var ip = "192.168.22.80"; //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// 请自行修改以上变量值 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) {oWebControl.JS_Resize(1000, 600); // 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});});
}
//获取公钥
function getPubKey(callback) {oWebControl.JS_RequestInterface({funcName: "getRSAPubKey",argument: JSON.stringify({keyLength: 1024})}).then(function (oData) {console.log(oData, 'odate');if (oData.responseMsg.data) {pubKey = oData.responseMsg.data;callback()}})
//RSA加密
function setEncrypt(value) {var encrypt = new JSEncrypt();encrypt.setPublicKey(pubKey);return encrypt.encrypt(value);
5.通过WebControl 插件实例调用API方法操作功能（预览，回放，抓图、录像等）
经过上面4个步骤，初始化工作已经全部完成，接下去就是使用api去操作实例实现对应功能
(1)预览功能,funcName: "startPreview",
var cameraIndexCode='1e48db29e22143118441b75d199999dd'; //获取输入的监控点编号值，必填，从后端接口返回获取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 = 1; //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）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})}).then(res=>{console.log(res,'res')})// value为字符串，JS_RequestInterface仅接收json格式的变量，且需要先解析出argument，并且将argument字段的内容转为字符串
function requestInterface(value){isJSON(value);var JsonParam = JSON.parse(value);var JsonArgument = JsonParam.argument;JsonParam.argument = JSON.stringify(JsonArgument);oWebControl.JS_RequestInterface(JsonParam).then(function (oData) {console.log(oData)});
}
// 判断字符串是否为json
function isJSON(str) {if (typeof str == 'string') {try {var obj=JSON.parse(str);if(typeof obj == 'object' && obj ){return true;}else{showCBInfo("param is not the correct JSON message");return false;}} catch(e) {showCBInfo("param is not the correct JSON message");return false;}}console.log('It is not a string!')
}// 单路播放轮巡函数
function SingleTourPreview() {// 解析轮巡的监控点编号var param = $("#TourPreviewCamIdx").val();//param = param.replace(/(\s*)/g, "");var cameraIndexArray = new Array();cameraIndexArray = param.split(",");var arraySize = cameraIndexArray.length;// 获取当前窗口个数var WndNum = 1;oWebControl.JS_RequestInterface({funcName: "getLayout"}).then(function (oData) {//分析窗口数var Data = JSON.stringify(oData.responseMsg.data);Data = Data.replace(/\\n/g, "");Data = Data.replace(/\\/g, "");Data = Data.replace(/\"{/g, "{");Data = Data.replace(/}\"/g, "}");WndNum = JSON.parse(Data).wndNum;for (i = 0; i < WndNum; i++){var cameraIdx = cameraIndexArray[i % arraySize];var previewParam = JSON.stringify({"argument": {"authUuid": "","cameraIndexCode": cameraIdx,"ezvizDirect": 0,"gpuMode": 0,"streamMode": 0,"transMode": 1,"wndId": i+1,"cascade": 1},"funcName": "startPreview"});requestInterface(previewParam);}});
// 批量播放轮巡函数
function MultiTourPreview() {// 解析轮巡的监控点编号var param = $("#TourPreviewCamIdx").val();//param = param.replace(/(\s*)/g, "");var cameraIndexArray = new Array();cameraIndexArray = param.split(",");var arraySize = cameraIndexArray.length;// 获取当前窗口个数var WndNum = 1;oWebControl.JS_RequestInterface({funcName: "getLayout"}).then(function (oData) {//分析窗口数var Data = JSON.stringify(oData.responseMsg.data);Data = Data.replace(/\\n/g, "");Data = Data.replace(/\\/g, "");Data = Data.replace(/\"{/g, "{");Data = Data.replace(/}\"/g, "}");WndNum = JSON.parse(Data).wndNum;var multiPlayParam = {"argument": {"list": []},"funcName": "startMultiPreviewByCameraIndexCode"}for (i = 0; i < WndNum; i++){var PlayParam = {"authUuid": "","cameraIndexCode": cameraIndexArray[i % arraySize],"ezvizDirect": 0,"gpuMode": 0,"streamMode": 0,"transMode": 1,"wndId": i+1}multiPlayParam.argument.list.push(PlayParam);}var previewParam = JSON.stringify(multiPlayParam);requestInterface(previewParam);});
}(2)设置窗口布局
oWebControl.JS_RequestInterface({funcName: " setLayout",argument: {layout:'2x2',//窗口布局}})(3)抓图
oWebControl.JS_RequestInterface({funcName: "snapShot",argument：{name:'D:\test.jpg'//图片绝对路径名称},});总结：
其他功能对着开发文档API调用就行了
所有功能调用都是通过
oWebControl.JS_RequestInterface({funcName: "",//例如：startPreview预览功能argument：{}})这个API实现，不同功能通过funcName值区别，argument为该功能需要传递的参数
6.离开页面断开与插件服务连接
释放资源
// 标签关闭
$(window).unload(function () { 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_Disconnect().then(function(){}, function() {});}
});四、窗口事件绑定
海康播放插件本质是ActiveX控件，无法通过css控制位置和大小，当页面窗口大小变化或者遇到页面有滚动条情况就需要手动设置插件窗口位置和大小，可以通过JS_Resize （调整插件窗口大小、位置），JS_CuttingPartWindow （扣除部分插件窗口）两个api来实现
// 监听resize事件，使插件窗口尺寸跟随DIV窗口变化
$(window).resize(function () {if (oWebControl != null) {oWebControl.JS_Resize(1000, 600);//oWebControl.JS_Resize(800, 400);setWndCover();}
});
// 监听滚动条scroll事件，使插件窗口跟随浏览器滚动而移动
$(window).scroll(function () {if (oWebControl != null) {oWebControl.JS_Resize(1000, 600);//oWebControl.JS_Resize(800, 400);setWndCover();}
});// 设置窗口裁剪，当因滚动条滚动导致窗口需要被遮住的情况下需要JS_CuttingPartWindow部分窗口
function setWndCover() {var iWidth = $(window).width();var iHeight = $(window).height();var oDivRect = $("#playWnd").get(0).getBoundingClientRect();var iCoverLeft = (oDivRect.left < 0) ? Math.abs(oDivRect.left) : 0;var iCoverTop = (oDivRect.top < 0) ? Math.abs(oDivRect.top) : 0;var iCoverRight = (oDivRect.right - iWidth > 0) ? Math.round(oDivRect.right - iWidth) : 0;var iCoverBottom = (oDivRect.bottom - iHeight > 0) ? Math.round(oDivRect.bottom - iHeight) : 0;iCoverLeft = (iCoverLeft > 1000) ? 1000 : iCoverLeft;iCoverTop = (iCoverTop > 600) ? 600 : iCoverTop;iCoverRight = (iCoverRight > 1000) ? 1000 : iCoverRight;iCoverBottom = (iCoverBottom > 600) ? 600 : iCoverBottom;oWebControl.JS_RepairPartWindow(0, 0, 1001, 600); // 多1个像素点防止还原后边界缺失一个像素条if (iCoverLeft != 0) {oWebControl.JS_CuttingPartWindow(0, 0, iCoverLeft, 600);}if (iCoverTop != 0) {oWebControl.JS_CuttingPartWindow(0, 0, 1001, iCoverTop); // 多剪掉一个像素条，防止出现剪掉一部分窗口后出现一个像素条}if (iCoverRight != 0) {oWebControl.JS_CuttingPartWindow(1000 - iCoverRight, 0, iCoverRight, 600);}if (iCoverBottom != 0) {oWebControl.JS_CuttingPartWindow(0, 600 - iCoverBottom, 1000, iCoverBottom);}
