在上面实现的基础上,对接海康威视摄像头实现摄像头预览效果。
该型号只支持IE模式取流。

实现
1、去官网-硬件产品-WEB开发包下载官方示例代码。
由于这里的设备不支持websocket取流,所以下载下面的3.0的开发包。
2、按照上面博客中建表与生成前后端代码,进而实现对摄像头参数的管理。
实现预览的主要参数包括Ip、端口号、登录名、登录密码。其他的都是额外加的参数。
3、勾选摄像头进行预览,限制最多选择四个,否则浏览器会卡顿。
<el-table
v-loading="loading"
:data="videoList"
@selection-change="handleSelectionChange"
>
多选事件处理
// 多选框选中数据
handleSelectionChange(selection) {
this.openVideoData = [];
this.openVideoData = selection;
this.ids = selection.map((item) => item.id);
this.single = selection.length !== 1;
this.multiple = !selection.length;
},
需要提前声明变量
data() {
return {
// 遮罩层
loading: false,
// 选中数组
ids: [],
// 非单个禁用
single: true,
// 非多个禁用
multiple: true,
4、点击预览按钮实现跳转到预览的新标签页
<el-button
type="success"
plain
icon="el-icon-setting"
size="mini"
:disabled="multiple"
@click="videoChange"
>预览</el-button
>
预览按钮的点击事件
// 查看摄像
videoChange() {
let routeUrl = this.$router.resolve({
path: "/carVideo",
query: {
videoData: JSON.stringify(this.openVideoData),
},
});
if (this.openVideoData.length > 4) {
this.$notify({
title: "失败",
message: "最多支持预览选择4个摄像头",
type: "error",
});
} else {
window.open(routeUrl.href, "_blank");
}
},
首先校验最多选择四个,然后跳转到新的预览页面/carVideo。
首先配置路由,打开src/router下的index.js,添加路由
{
path: '/carVideo',
component: Layout,
component: (resolve) => require(['@/views/system/cameramap/component/video'], resolve),
meta: {title: '摄像头'},
hidden: true,
},
然后跳转路由时携带了要进行预览的摄像头参数this.openVideoData
5、预览页面video.vue引入官网的webVideoCtrl.js文件
首先该页面中需要引入官网的webVideoCtrl.js文件,在根目录下新建static目录,将js文件放在该目录下
引入
import { WebVideoCtrl } from "/static/webVideoCtrl.js";
6、video.vue判断当前是否为IE/兼容模式
data中获取请求代理
ua: navigator.userAgent.toLocaleLowerCase(),
created方法中进行判断并提示
created() {
if (this.ua.match(/msie/) != null || this.ua.match(/trident/) != null) {
this.browserType = "IE";
this.videoData = JSON.parse(this.$route.query.videoData);
if (this.videoData.length <= 1) {
this.iWndowType = 1;
} else if (this.videoData.length > 1 && this.videoData.length <= 4) {
this.iWndowType = 2;
}
} else {
this.$notify({
title: "失败",
message: "请在ie模式下查看摄像头",
type: "error",
});
}
},
7、初始化预览页面
在mounted中执行初始化界面的操作
mounted() {
this.videoChange();
},
在方法中
videoChange() {
setTimeout(() => {
this.videoInitPlugin(); // 初始化video界面
}, 300);
},
调用videoInitPlugin中校验是否已经安装插件,插件位置为开发包中exe文件
校验是否已经安装插件的方法
videoInitPlugin() {
this.$nextTick(() => {
var iRet = WebVideoCtrl.I_CheckPluginInstall();
if (iRet === -1) {
// alert("您还未安装过插件,双击开发包目录里的WebComponentsKit.exe安装");
this.myFunction();
return;
}
this.initPlugin();
});
},
myFunction() {
var r = confirm("您还未安装过插件,请下载后查看摄像!");
if (r == true) {
window.location.href = "/WebComponentsKit.exe";
} else {
}
},
如果没有安装插件会进行提示并且确定后进行下载,所以将WebComponentsKit.exe
放在代码中public目录下
如果已经安装插件则执行官方js中初始化插件的方法
initPlugin() {
WebVideoCtrl.I_InitPlugin("100%", "100%", {
bWndFull: true, //是否支持单窗口双击全屏,默I_CheckPluginInstall
iWndowType: this.iWndowType, //默认展示几个摄像头1x1 2x2
cbInitPluginComplete: function () {
WebVideoCtrl.I_InsertOBJECTPlugin("divPlugin");
// 检查插件是否最新
if (WebVideoCtrl.I_CheckPluginVersion() === -1) {
return;
}
},
});
for (var i = 0; i < this.videoData.length; i++) {
this.hkvInfo = this.videoData[i];
this.index = i;
this.onLogin();
}
},
然后是遍历选择的所有摄像头进行登录操作。
8、摄像头登录
// 登录
async onLogin() {
var that = this;
that.loginLoading = true;
// 登录设备
WebVideoCtrl.I_Login(
that.hkvInfo.ip,
that.iProtocol,
that.hkvInfo.port,
that.hkvInfo.username,
that.hkvInfo.password,
{
async: false,
success: (xmlDoc) => {
//TODO 获取通道信息
that.getChannelInfo();
that.getDevicePort(that.hkvInfo.ip + "_" + that.hkvInfo.port);
that.loginLoading = false;
this.clickStartRealPlay();
},
error: function () {
that.loginLoading = false;
that.$message({
showClose: true,
message: "登录失败",
type: "error",
});
},
}
);
},
9、登录成功后调用预览
在登录成功后直接调用预览方法
clickStartRealPlay() {
console.log("开始预览", this.index);
// 开始预览
var that = this;
that.startPlayLoading = true;
var szDeviceIdentify = that.hkvInfo.ip + "_" + that.hkvInfo.port;
that.startRealPlay(szDeviceIdentify, this.index, that.hkvInfo.channels[0]);
that.startPlayLoading = false;
},
startRealPlay(szDeviceIdentify, iWndIndex, iChannelID) {
var that = this;
WebVideoCtrl.I_StartRealPlay(szDeviceIdentify, {
iRtspPort: that.iRtspPort,
iWndIndex: iWndIndex,
iChannelID: iChannelID,
bZeroChannel: that.bZeroChannel,
success: function () {
// that.$notify({
// title: "成功",
// message: "开始预览通道" + iChannelID + "成功",
// type: "success",
// });
},
error(status, xmlDoc2) {
console.log(xmlDoc2); //不能删除
// that.$notify({
// title: "失败",
// message: "开始预览通道" + iChannelID + "失败",
// type: "error",
// });
if (status === 403) {
console.log("szInfo 设备不支持Websocket取流!");
} else {
console.log("开始预览失败 ", status, xmlDoc2);
}
},
});
},
10、在页面销毁关闭时停止预览并退出登录
destroyed() {
this.clickStopRealPlay();
this.onLogout();
},
停止预览
clickStopRealPlay: function () {
for (var i = 0; i < = this.index; i++) {
setTimeout(this.stopRealPlay(i), 1000);
}
},
stopRealPlay: function (iWndIndex) {
var that = this;
WebVideoCtrl.I_Stop({
iWndIndex: iWndIndex,
success: function () {
// that.$notify({
// title: "成功",
// message: "停止预览窗口" + iWndIndex + "成功",
// type: "success",
// });
},
error: function () {
// that.$notify({
// title: "失败",
// message: "停止预览窗口" + iWndIndex + "失败",
// type: "error",
// });
},
});
},
退出登录
// 退出
onLogout() {
this.videoData.forEach((element) => {
var szDeviceIdentify = element.ip + "_" + element.port;
var iRet = WebVideoCtrl.I_Logout(szDeviceIdentify);
if (0 == iRet) {
// this.$message({
// showClose: true,
// message: "退出成功",
// type: "success",
// });
} else {
// this.$message({
// showClose: true,
// message: "退出失败",
// type: "error",
// });
}
});
},
