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
<template>

},
},
}
</script>
以上是封装的组件,下面是调用的方法
<iSecureCenterContainer :iSecureCenterConfig="iSecureCenterConfig" ref="iSecureCenterRef" />
//先引入组件
在data中定义的 iSecureCenterConfig: {
appkey: '',
secret: '',
ip: '',
playMode: 0,
snapDir: 'D:\SnapDir',
videoDir: 'D:\VideoDir',
layout: '3x3',
cameraIndexCodeList: [],
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) {
if (data == 'shishi') {
this.info = '实时视频'
this.iSecureCenterConfig = {
...this.iSecureCenterConfig,
playMode: 0,
layout: "3x3"
}
} else {
this.info = '历史视频'
this.iSecureCenterConfig = {
...this.iSecureCenterConfig,
playMode: 1, //1是回放
layout: "1x1"
}
}
},
