HTTP request methods
Implement the HTTP request on the following URI, where supermapiserver is the server name, with png being the output format.
http://supermapiserver:8090/iserver/services/map-svtiles-China/rest/maps/China/tileFeature/symbols/SYMBOLMARKER__TraStation_pt@POI_Other__64__64__true__1463419621.png

Response example
Perform GET request on the vectorSymbol resource: http://supermapiserver:8090/iserver/services/map-China100/rest/maps/China/tileFeature/symbols/SYMBOLMARKER__beijing@China__64__64__true__12081270.png
The returned point symbol is as follows:
HEAD request
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 vectorSymbol resource exists or whether the client has authority to access the resource. It can quickly determine whether the vectorSymbol resource supports the representation in <format> format by performing HEAD request on URI with <format>.
