下载并安装海康插件 webcontrol.exe
直接就写代码把,所有方法都是海康他们直接封装好的demo
初始化之后,后台把密钥和一些配置的东西返回给你
然后只需要把监控点编号给你就可以了。实现之后几乎你想要的操作都有
各种黑科技,而你只需处理这个插件的兼容问题和一些bug,底层他们时用C写得,但是最终实现播放呢,又是webscoket实现的。
在index.html中引入下面这三个js
采用了动态获取容器的宽和高
<div id="playWnd" class="playWnd" :style="{width:swfWidth+'px',height:swfHeight+'px'}"></div>
swfHeight: "",
swfWidth: "",
//初始化参数
initparam: {
appKey: "xxxxx",
secret: "xxxxxxx",
apiIp: "xxx.xxx.xxx",
apiPort: 8099,
layout: "1x1"//这里是来控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
//海康插件页面渲染方法
//Html: 就是放插件的盒子,id不要改,改了的话下面的方法里面也要改
//css:自己写一个盒子,让上面这个盒子100%就好
//js:data,methods,生命周期函数里面也要去看下
//想要用海康视频直接把从onSearch以下的所以方法复制过去
// 前面三个接口是我们自己要写的
//查询videoList,密钥getInitParam,执行就是videoPreview

this.oWebControl.JS_ShowWnd();
