ArcGIS Server APIs
SOAP
1)XML-structured 語言。
2) 對(duì) server objects 和 server object extensions 可用。
3) 設(shè)計(jì)用作 stateless 交互。
4)Catalog 請求由 IServerCatalogAdmin 接口處理。
5)Service 請求由 IRequestHandler 接口處理。
ArcObjects
1) 遠(yuǎn)程與 GIS Server 上的 ArcObjects 交互。
2) 使用客戶端的 Primary Interop Assemblies (PIA) 和 object libraries 。
3) 通過 SOM 訪問獲得 ArcGIS Server services 。
4) 設(shè)計(jì)用作 stateless 和 stateful 交互。

ArcGIS Server MapResource 類型

A 、 MapResourceInternet – 連接到 Web service endpoint

B 、 MapResourceLocal – 連接到 Server Object Manager

1) 訪問 ServerContext

2) 使用 ArcObjects

?

ArcGIS Server Internet: SOAP 編程

1)MapResourceInternet

MapServerProxy, 訪問 value objects

2) 通訊是 stateless

3) 使用 pooled objects

Dim mapRes as ESRI.ArcGIS.ADF.Web.DataSources.ArcGISServer.MapResourceInternet

mapRes = gisFunc.Resource

Dim mapsProxy as ArcGISServer.MapServerProxy = mapRes.MapServerProxy

Dim mapInfo as ArcGISServer.MapServerInfo =

mapsProxy.GetServerInfo(mapsProxy.GetDefaultMapName())

Dim mapDesc as ArcGISServer.MapDescription = mapInfo.DefaultMapDescription

Dim mLayerInfo as ArcGIServer.MapLayerInfo()

mLayerInfo = mapRes.MapServerInfo.MapLayerInfos

Dim layerDescs as ArcGISServer.LayerDescription()

layerDescs = mapDesc.LayerDescriptions

?

ArcGIS Server Local: ArcObjects 編程

1) 遠(yuǎn)程訪問 ArcObjects

2)MapServerLocal

MapServer > IMapServer (COM) >IMapServerObjects (COM)

3) 通過 .NET 部件訪問高級(jí)的 functionality

?

Dim mapFunc as IMapFunctionality = Map1.GetFunctionality(0)

Dim ags_mr as ESRI.ArcGIS.ADF.Web.DataSources.ArcGISServer.MapResourceLocal

ags_mr =

CType(mapFunc.Resource,ESRI.ArcGIS.ADF.Web.DataSources.ArcGISServer.MapResourceLocal)

' Access the ArcObjects COM ServerObject directly

Dim mapServer as ESRI.ArcGIS.Carto. IMapServer = CType(ags_mr.MapServer,IMapServer)

Dim mapServerObjs as ESRI.ArcGIS.Carto.IMapServerObjects

mapServerObjs = CType(mapServer,IMapServerObjects)

Dim map as ESRI.ArcGIS.Carto.IMap = mapServerObjs.Map

' Now perform more ArcObjects operations

Dim featClass as IFeatureClass = CType(map.Layers(0)).FeatureClass,

?

深入 ArcGIS Server Local API

1)MapResourceLocal

通過 DCOM 訪問 server 上的 ArcObjects

ServerContext

2) 所有的過程在遠(yuǎn)程完成

    --首先建立連接

Identity identity = new Identity("username", "pwd", "domain");
AGSServerConnection connection = new AGSServerConnection("fmc-pca187", identity);
connection.Connect();

--獲得服務(wù)器對(duì)象

IServerObjectManager m_pSOM = connection. ServerObjectManager ;
IServerContext m_pServerContext = m_pSOM. CreateServerContext (" testMap" , "MapServer" ) ;
IMapServer pMapServer = m_pServerContext . ServerObject　　as IMapServer ;

--使用服務(wù)器對(duì)象

IMapServerObject s pMapServerObject s = ( IMapServerObject s) pMapServer ;
IMap pMap = pMapServerObject s. get_Map (pMapServer .DefaultMapName) ;
IFeatureLayer p FLayer = ( IFeatureLayer) pMap. get_Layer(0) ;
IFeatureClass p FeatureClass = p FLayer . FeatureClass ;
int i = p FeatureClass. FeatureCount (null) ; 

--釋放服務(wù)器對(duì)象

m_pServerContext . ReleaseContext () ;
