资源层次

HTTP 请求方法

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/spatialanalyst-sample/restjsr/spatialanalyst/datasets/SamplesP@Interpolation.rjson

GET 请求

获取数据集信息，以及其子资源，即支持的空间分析操作（不同类型的数据集支持不同的空间分析功能）。

响应结构

返回的是 DatasetInfo 类型的表述。

字段 类型 说明
datasetInfo DatasetInfo 数据集信息。
childResourceInfos List<ChildResourceInfo> 子资源信息，即针对此数据集可进行的空间分析操作的列表。

响应示例

对 dataset 资源：http://localhost:8090/iserver/services/spatialanalyst-sample/restjsr/spatialanalyst/datasets/SamplesP@Interpolation.rjson，执行 GET 请求，返回 RJSON 格式的响应如下：

HEAD 请求

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