<border_uri>/{datasetBorderResultID}[.<format>]
模型数据集提取边界的结果资源。
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/spatialAnalysis-BIM/restjsr/spatialanalyst/datasets/结构柱@8ExportModel/border/{datasetBorderResultID}.rjson
返回提取边界的结果资源。
对资源执行 GET 请求后，响应参数如下：
| 字段 | 类型 | 说明 |
| geometries | Geometry3D | 提取边界的结果，即获取模型数据集的边界结果。 |
| succeed | boolean | 提取边界操作是否成功；成功则返回 true，否则返回 false。 |
| message | String | 提取边界过程中产生的相关信息。 |
对datasetBorderResult 资源：http://supermapiserver:8090/iserver/services/spatialAnalysis-BIM/restjsr/spatialanalyst/datasets/结构柱@8ExportModel/border/3e317537d15d45b6adfa6cb9898c923d.rjson执行 GET 请求后，返回的 json 结果如下：

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 datasetBorderResult 资源是否存在，或者客户端是否有权限访问 datasetBorderResult 资源。通过对加.<format>的 URI 执行 HEAD 请求，还可以快速判断 datasetBorderResult 资源是否支持<format>格式的表述。
