在vue中使用海康插件实现视频实时监控(海康插件)

首先

下载并安装海康插件 webcontrol.exe

然后

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。

代码

在index.html中引入下面这三个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>
data:
     swfHeight: "",
     swfWidth: "",
    //初始化参数

        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",

      oWebControl: null,
      WebControl: null
methods:
//海康插件页面渲染方法
    //Html:<div id="playWnd" class="playWnd"></div> 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
