vue使用海康视频web插件

完成的效果是：点击按钮然后弹出所播放的视频

使用的海康web插件：由海康官网下载的视频WEB插件V1.5.2版本，解压完毕后目录如下：

第一步：安装插件

安装在bin文件下面的VideoWebPlugin.exe

第二步：引入必要的文件

在public下面创建文件夹，文件名称可以自己起名字，我这里的是lib下面的js，然后把demo文件下的jquery-1.12.4.min.js、jsencrypt.min.js、web-control_1.2.5.min.js三个文件复制到所创建的文件夹下，最后在public/index.html引入所需要的文件

引入：

<!-- 视频插件 -->
<script src="<%= BASE_URL %>lib/js/jquery-1.12.4.min.js" charset="utf-8"></script>
<script src="<%= BASE_URL %>lib/js/jsencrypt.min.js" charset="utf-8"></script>
<script src="<%= BASE_URL %>lib/js/web-control_1.2.5.min.js" charset="utf-8"></script>

然后在views下面创建一个vue文件：

父组件：
<template>
    <div>
        <el-button @click="talkTo()">播放</el-button>
        <div v-if="dialogVisible && cameraId"
          style="width: 100%;height: 100%;position: absolute;background: transparent;z-index: 1111;"
        >
            <div style="
                width: 2200px;
                position: absolute;
                top: 23%;
                left: 31%;
                background-color: #122559;
                z-index: 1111;
                padding: 0 30px;
            ">
                <div style="color: #fff;font-size: 30px;text-align: right;cursor: pointer;" @click="close()">x</div>
                <stationVideo ref="stationVideo" v-show="dialogVisible" :cameraId="cameraId">                    
                </stationVideo>
             </div>
        </div>
    </div>
</template>
<script>
import stationVideo from "./stationVideo"
export default {
    components: {
        stationVideo
    },
    data() {
        return {
            dialogVisible: false,
            cameraId: "",//通过接口拿到的每个视频的id
        }
    },
    methods: {
        //关闭窗口
        close() {
            this.dialogVisible = false
            this.$refs.stationVideo.hideWindow()
        },
        talkTo() {      
            this.dialogVisible = true
        }
    }
}
</script>

子组件：
<template>
  <div style="width: 2200px; height: 1000px">
    <div id="playWnd" class="playWnd" style="left: 109px; top: 133px"></div>
  </div>
</template>

里面的appkey，secret，ip等必要参数需要联系海康的对接人员，摄像头的编号值（cameraIndexCode）这个需要从接口获取

效果图：鼠标hover的时候出现操作栏
