首先第一步，在海康官网下海康视频插件下载到电脑中海康开放平台
然后新建一个组件，下面我直接把我封装好的组件代码拿出来，重要的地方我在代码中添加了注释

</script>以上是封装的组件，下面是调用的方法
javascript

//先引入组件
在data中定义的 iSecureCenterConfig: {

previewCode: '',
},
//点击视频的时候触发的方法 判断是历史视频还是实时预览
handleNodeClick(data) {
console.log(data)
if (this.iSecureCenterConfig.playMode === 0) {
this.iSecureCenterConfig = {
...this.iSecureCenterConfig,
previewCode: data.code,
}
} else {
this.$refs.iSecureCenterRef.oWebStartPlayback(data.code)
}
},
//实时，历史视频切换，
videoChange(data) {
