URI
<vectorMap_uri>/v2/vectortile/sprites/sprite[.<format>]
支持的方法
父资源
介绍
通过对 sprites 资源执行 GET 请求，可获取指定样式地图中 sprite 图集信息。当表述为图片格式时，例如PNG，可获取 sprite 图，当表述为 JSON 格式时，则返回用于定位图标位置的元数据信息。同时支持获取两倍放大的 sprite 图集信息，URI示例为< vectorMap_uri>/sprites/sprite@2x[.<format>]。
支持的方法：
支持的表述格式：RJSON、JSON、PNG、BMP、JPG。
HTTP 请求方法
对如下 URI 执行 HTTP 请求，以PNG、JSON 输出格式为例加以说明，其中，supermapiserver 是服务器名。
http://supermapiserver:8090/iserver/services/vectorMap-DLTB-public/restjsr/v2/vectortile/sprites/sprite.png
http://supermapiserver:8090/iserver/services/vectorMap-DLTB-public/restjsr/v2/vectortile/sprites/sprite.json
GET 请求
获取当前地图中的 sprite 图集信息。
请求参数
对 sprites 资源执行 GET 请求，获取 sprite 图集信息，需要在 URI 中包含相关参数。参数如下所示：
| 名称 | 类型 | 含义 |
| styleID | String | 矢量瓦片电子地图样式 id，可以为同一个服务提供多个样式。 |
响应示例
执行 GET 请求：http://supermapiserver:8090/iserver/services/vectorMap-DLTB-public/restjsr/v2/vectortile/sprites/sprite.png?styleID=DLTB，则返回的结果如下图：

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