http://supermapiserver:8090/iserver/services/map-China400/rest/maps/World/tileFeature/vectorStyles.rjson
Get the style information for specified layers.
Request a GET request for a vectorstyles resource to get the style information for the specified layer in the map. You need to include the relevant parameters in the URI. If no parameters are specified, the style information for all the layers in the map is acquired by default. The parameters are:
| Name | Type | Description |
| type | VectorStyleType | The description language type of the layer style. Currently only supports CartoCSS language. |
| layerNames | String | The layer name to be queried. E.g., ["Countries@World","Lakes@World@@World"]. |
Returns information that contains the layer name and its style.
| Field | Type | Description |
| type | VectorStyleType | The description language type of the layer style, which is CartoCSS. |
| style | String | The layer style information. It includes the layer name and its style. |
To request the layer style information of China_Nation_txt_1@China and China_Hyd_R@China400 in the China400 map on the vectorStyles resource, perform the GET request:
http://supermapiserver:8090/iserver/services/map-China400/rest/maps/China/tileFeature/vectorstyles?type=cartoCSS&layerNames=%5B"China_Nation_txt_1@China","China_Hyd_R@China400"%5D.
The rjson resource representation returned is as follows:#China_Hyd_R@China400[zoom>=2.1634093716513974E-7]

Returns the same HTTP response header as the GET request, but does not have the response entity. It can get the metadata information in the response header without transferring the whole response content. Metadata information includes media type, character encoding, compression encoding, entity content length, and so on.
The HEAD request can be used to determine whether the vectorStyles resource exists or whether the client has authority to access the resource. It can quickly determine whether the vectorStyles resource supports the representation in <format> format by performing HEAD request on URI with <format>.
