在vue中应用海康插件实现视频实时监控(海康插件)
首先
下载并装置海康插件 webcontrol.exe
而后
间接就写代码把，所有办法都是海康他们间接封装好的demo
初始化之后，后盾把密钥和一些配置的货色返回给你
而后只须要把监控点编号给你就能够了。实现之后简直你想要的操作都有
各种黑科技，而你只需解决这个插件的兼容问题和一些bug,底层他们时用C写得，然而最终实现播放呢，又是webscoket实现的。
代码
在index.html中引入上面这三个js
<script src="./static/hkjs/jquery-1.12.4.min.js"></script>
<script src="./static/hkjs/jsencrypt.min.js"></script>
<script src="./static/hkjs/jsWebControl-1.0.0.min.js"></script>
html:
采纳了动静获取容器的宽和高
<div id="playWnd" class="playWnd" :style="{width:swfWidth+'px',height:swfHeight+'px'}"></div>
data:
swfHeight: "",
swfWidth: "",
//初始化参数
initparam: {
appKey: "xxxxx",
secret: "xxxxxxx",
apiIp: "xxx.xxx.xxx",
apiPort: 8099,
layout: "1x1"//这里是来管制你一开始初始化之后的分屏的
},
//监控点编号
pointCode: "xxxxxxx",
pubKey: "",
oWebControl: null,
WebControl: null
methods:
//海康插件页面渲染办法
//Html：<div id="playWnd" class="playWnd"></div> 就是放插件的盒子,id不要改，改了的话上面的办法外面也要改
//css:本人写一个盒子，让下面这个盒子100%就好
//js:data，methods,生命周期函数外面也要去看下
//想要用海康视频间接把从onSearch以下的所以办法复制过来
// 后面三个接口是咱们本人要写的
//查问videoList,密钥getInitParam,执行就是videoPreview
