实现海康监控视频播放（录像回放）（抓拍，录像等功能）

1. 将需要存储的监控抓拍和录像功能存储到本地磁盘，使用输入报存到浏览器缓存里。在created拿取缓存数据，判断缓存里是否有数据。如果没有弹出输入框。

        <div v-if="cache == true"><el-form><div>抓图存储地址</div><el-form-item><el-inputv-model="address.snapDir"placeholder="如：D:\monitor\Snapshot"style="width: 240px"></el-input></el-form-item><div>录像存储地址</div><el-form-item><el-inputv-model="address.videoDir"placeholder="如：D:\monitor\Vedio"style="width: 240px"></el-input></el-form-item></el-form><el-button @click="fun">保存存储地址</el-button></div>

created() {this.result = window.localStorage.getItem("message_2");if (this.result != null) {this.localStorage = JSON.parse(this.result);} else {this.cache = true;}},methods: {fun() {//对象解析Wie字符串if (this.address.snapDir != undefined &&this.address.videoDir != undefined) {window.localStorage.setItem("message", JSON.stringify(this.address));this.localStorage = this.address;this.cache = false;this.$modal.$msgSuccess("添加成功");} else {this.$message("请输入完整");}},}

2. 这边逻辑是先调接口拿区域，通过区域查询区域下的监控点，点击监控点之后选择开始时间和结束时间。

注意：这里的时间只接受时间戳，以秒为单位，如果你转义的时间戳为毫秒那么需要除1000。

     <el-tabsv-model="activeName"type="card":stretch="true"@tab-click="handleClick"v-if="status == true"><el-tab-pane label="监控区域" name="0"><RegionDept @handleNodeClick="handleNodeClick"></RegionDept></el-tab-pane><el-tab-pane :label="label" name="1"><divclass="monitor"v-for="(item, index) in previewList":key="item.cameraAreaId"><spanclass="monitor1":class="active == index ? 'monitor2' : ''"@click="showClick(item, index)">{{ item.name }}</span></div></el-tab-pane></el-tabs><el-formv-if="status == false":model="queryParams"ref="queryForm"size="small":inline="true"style="text-align: center"><el-form-item prop="beginTime"><el-date-pickerv-model="queryParams.startTime"type="datetime"value-format="yyyy-MM-dd HH:mm:ss"placeholder="选择开始时间"></el-date-picker></el-form-item><el-form-item prop="endTime"><el-date-pickerv-model="queryParams.endTime"type="datetime"value-format="yyyy-MM-dd HH:mm:ss"placeholder="选择结束时间"></el-date-picker></el-form-item><el-button type="primary" @click="submitForm">查询</el-button></el-form>

    submitForm() {// 这里是日期格式转时间戳，以秒为单位就不需要除1000，毫秒则需要除1000this.startTime = Date.parse(this.queryParams.startTime)/1000;this.endTime = Date.parse(this.queryParams.endTime)/1000;console.log(this.startTime,this.endTime);this.previewVideo(this.boxList);this.status = true;},
