<reconstructtracks_uri>/{jobID}[.<format>]
reconstructtracksJob 资源表示一个轨迹重建作业。通过对 reconstructTracksJob 资源执行 GET 请求，可以获取一个轨迹重建作业详细配置信息，可通过 ID 号（{jobID}） 来获取。
支持的方法：
支持的表述格式：RJSON、JSON、HTML、XML。
对如下 URI 执行 HTTP 请求，以 rjson 输出格式为例加以说明，其中，supermapiserver 是服务器名。
http://supermapiserver:8090/iserver/services/distributedanalyst/rest/v1/jobs/spatialanalyst/reconstructtracks/{jobID}.rjson
获取一个轨迹重建作业详细配置信息
对 reconstructTracksJob 资源执行 GET 请求，返回操作结果的结构如下：
| 字段 | 类型 | 说明 |
| id | String | 应用ID。 |
| state | SparkJobState | 任务状态。包括执行状态、起止时间、耗时等。 |
| setting | SparkJobSetting | 列举当前轨迹重建作业任务的详细信息。 |

返回跟 GET 请求一样的 HTTP 响应头，但是没有响应实体。可以在不必传输整个响应内容的情况下，获取包含在响应消息头中的元数据信息。元数据信息包括媒体类型，字符编码，压缩编码，实体内容长度等。
HEAD 请求可以用来判断 reconstructtracksJob 资源是否存在，或者客户端是否有权限访问 reconstructtracksJob 资源。通过对加.<format>的 URI 执行 HEAD 请求，还可以快速判断 reconstructtracksJob 资源是否支持<format>格式的表述。
