getPlaybackUrl static method

Future getPlaybackUrl({ String? cameraIndexCode, String? beginTime, String? endTime, int recordLocation = 0, int version = 2, bool isHttps = false, })

获取回放地址url

cameraIndexCode：摄像头标识

beginTime：开始时间(ISO8601格式：yyyy-MM-dd’T’HH:mm:ss.SSSXXX，例如北京时间：2017-06-14T00:00:00.000+08:00)

endTime：结束时间(ISO8601格式：yyyy-MM-dd’T’HH:mm:ss.SSSXXX，例如北京时间：2017-06-15T00:00:00.000+08:00)

recordLocation: 存储类型 0,中心存储 1,设备存储

version：1是海康SDK1.3版本，默认是2海康SDK1.4版本

isHttps是否为https请求
