URI

<vectorTileService_uri>/resources/styles/root.json

支持的方法

GET、HEAD

介绍

对 vectorTileStyle 资源执行 GET 请求，可获取当前地图的 Mapbox 标准风格信息，包括图集和字体属性，以及遵循的 Mapbox 样式规范版本。详细介绍可参见 Mapbox 官网（http://www.mapbox.com/mapbox-gl-js/style-spec）。

支持的方法：

• GET：获取当前地图的风格信息。
• HEAD：检查 vectorTileStyle 资源是否存在，或权限是否可以访问 vectorTileStyle 资源。

HTTP 请求方法

对如下 URI 执行 HTTP 请求，其中，supermapiserver 是服务器名，{component}是服务组件名，{mapName}是地图名。

http://supermapiserver:8090/iserver/services/{component}/arcgisrest/{mapName}/VectorTileServer/resources/styles/root.json

GET 请求

获取当前地图的风格信息。

请求参数

无。

响应结构

对 vectorTileStyle 资源执行 GET 请求，返回的资源表述的结构如下：

字段	类型	说明
version	double	当前使用的 Mapbox GL 样式规范版本，该参数为8
sprite	String	图集资源的 url 请求路径，该值为 ../sprites/sprite
glyphs	String	字体资源的 url 请求路径，该值为 ../fonts/{fontstack}/{range}.pbf
sources	object	当前矢量瓦片服务中所有的图层样式源
layers	object	当前矢量瓦片服务中所有样式图层的Mapbox标准风格信息，主要包括如下字段： 1.id（必选）：图层ID 2.type（必选）：图层样式类型 3.source：此图层样式源的名称，在 sources 对象中定义 4.source-layer：该样式图层对应的矢量瓦片中的源图层 5.filter：用于控制图层的显示条件，通过条件表达式来实现仅显示与过滤器匹配的要素 6.layout：此图层的默认布局样式 7.paint：此图层的默认绘制样式

响应示例

对 vectorTileStyle 资源执行 GET 请求：http://supermapiserver:8090/iserver/services/vectorTile-China100/arcgisrest/China/VectorTileServer/resources/styles/root.json，则返回的结果如下：

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