【解决方法】a,通过临时图层制作专题图（接口为tempLayersSet）
b,iserver管理界面地图服务下资源tempLayers可以查看临时图层信息（有可视化图）
c,示例POST请求http://xxx:8090/iserver/services/map-china400/rest/maps/China/tempLayersSet.rjson
请求体为：[{
"name": "China",
"type": "UGC",
"subLayers": {
"layers": [
{
"type": "UGC",
"caption": "地区名称",
"ugcLayerType": "THEME",
"visible": true,
"theme": {
"labelExpression": "District_pt.Name",
"type": "LABEL",
"uniformStyle":{
"foreColor":{"red": 128,"blue": 0,"green": 0}
}
},
