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.rjson

GET 请求

获取数据源下所有的数据集信息。

响应示例

对 datasets 资源：http://supermapiserver:8090/iserver/services/spatialanalyst-sample/restjsr/spatialanalyst/datasets.rjson，执行 GET 请求，返回的是一个 dataset 描述集，其中每个{}中的是单个 dataset  的 RJSON 字符串描述，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 datasets 资源是否存在，或者客户端是否有权限访问 datasets 资源。通过对加.<format>的 URI 执行 HEAD 请求，还可以快速判断 datasets 资源是否支持<format>格式的表述。
