vue3+vite+ts引入海康威视监控

1.首先我们在海康威视官网上面下载这个
下载以后打开demo
把这三个文件放进你的public里面去

在vue3项目里的index.html引入

    <!--三个必要的js文件引入-->
    <script src="./public/hikvision/jquery-1.12.4.min.js"></script>
    <script src="./public/hikvision/jsencrypt.min.js"></script>
    <!-- 用于RSA加密 -->
    <script src="./public/hikvision/web-control_1.2.5.min.js"></script>
    <!-- 用于前端与插件交互 -->

2.新建一个监控复用组件,只需要通过props传入监控编号 就能使用了

index.vue

<!-- 海康威视组件 -->
