支持的方法：
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，{component}是服务组件名，{datasourceName}是数据源名，{layerID} 是图层 ID 号。
http://supermapiserver:8090/iserver/services/{component}/arcgisrest/{datasourceName}/FeatureServer/{layerID}/deleteFeatures.json
POST 请求
请求参数
对 deleteFeatures 资源执行 POST 请求，在指定图层中删除要素，需传递参数如下：
| 名称 | 类型 | 含义 |
| f | String | 响应格式，支持 json、pjson |
| where | String | 查询过滤器的 WHERE 子句。如： where=CITY_NAME = 'Barrington'。 |
| objectIds | int | 要查询的层的对象ID。如： objectIds=37, 462 |
| geometry | String | 用作空间过滤器的几何对象。几何的结构与 ArcGIS REST API 返回的 JSON 几何对象的结构相同。除了 JSON 结构外，对于 envelope 和 point，还可以使用逗号分隔语法来指定几何对象。如： geometry={xmin: -112, ymin: 32.6, xmax: -91.11, ymax: 41} geometry=-112,32.6,-91.11,41 geometry=-112,32.6 |
| geometryType | ArcGISGeometryType | 由 geometry 参数指定的几何类型。几何类型可以是esriGeometryPoint 、esriGeometryMultipoint 、esriGeometryPolyline、 esriGeometryPolygon、esriGeometryEnvelope。默认几何类型是 esriGeometryEnvelope。 |
| inSR | String | 输入几何对象的空间参考。 |
| spatialRel | String | 执行查询时要应用于输入几何对象的空间关系。支持的空间关系包括 esriSpatialRelIntersects、esriSpatialRelContains、esriSpatialRelCrosses、esriSpatialRelEnvelopeIntersects、esriSpatialRelIndexIntersects、esriSpatialRelOverlaps、esriSpatialRelTouches、esriSpatialRelWithin、esriSpatialRelRelation。默认的空间关系是 esriSpatialRelIntersects。 |
响应结构
对 deleteFeatures 资源执行 POST 请求删除指定图层的要素，返回的删除结果的结构如下：
| 字段 | 类型 | 说明 |
| id | int | 图层 id |
| deleteResults | EditResult[] | 删除要素结果集合 |
响应示例
对示例 deleteFeatures 资源：http://localhost:8090/iserver/services/data-BeijingAddress/arcgisrest/BeijingAddress/FeatureServer/0/deleteFeatures 执行 POST 请求，执行删除操作，请求体中的参数如下：
[
{
objectIds=37, 462
where=SMID > 10000
}
]
则返回的 pjson 格式的操作结果表述如下：

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