示例:从模型结果发布地理处理服务

本示例 Python 脚本运行模型并将结果作为地理处理服务发布到 ArcGIS Server。

脚本首先生成一些要素图层,然后从服务器工具工具箱运行提取数据任务模型。如果要素图层位置没有注册到 ArcGIS Server,则该脚本调用 arcpy.AddDataStoreItem 来注册数据库或文件夹。然后,脚本将调用 arcpy.CreateGPSDDraft 来从模型结果创建服务定义 (SD) 草稿文件。

分析 SD 草稿后,如果未发现错误,则该脚本将继续发布服务。

import arcpy
import os

connPath = "c:/gis/conections/myServer.ags"
sddraft = "c:/gis/gp/drafts/ExtractionDraft.sddraft"
sd = "c:/gis/gp/sd/AnalysisDraft.sd"

arcpy.env.workspace = "c:/gis/citydata"

# create layers which will be available as input
arcpy.MakeFeatureLayer_management('Wiarton.gdb/places/Cityhall', 'CityHall')
arcpy.MakeFeatureLayer_management('Wiarton.gdb/places/Airport', 'Airport')
arcpy.MakeFeatureLayer_management('Wiarton.gdb/places/FireStations', 'FireStations')

# run the extract data task and assign it to the 'result' variable
# only the cityhall layer was used as input, but the airport and firestation layers will be used in the service creation
aoi = "c:/gis/citydata/extract.shp"
result = arcpy.ExtractDataTask_server("CityHall", aoi, "File Geodatabase - GDB - .gdb", "ESRI GRID - GRID", os.path.join(arcpy.env.scratchFolder, "output.zip"))

# make sure the folder is registered with the server, if not, add it to the datastore
if arcpy.env.workspace not in [i[2] for i in arcpy.ListDataStoreItems(connPath, 'FOLDER')]:
     # both the client and server paths are the same
     dsStatus = arcpy.AddDataStoreItem(connPath, "FOLDER", "CityData", arcpy.env.workspace, arcpy.env.workspace)
     print "Data store : " + str(dsStatus)


# create service definition draft
arcpy.CreateGPSDDraft(
    result, sddraft, serviceName, server_type="ARCGIS_SERVER",
    connection_file_path=connPath, copy_data_to_server=False, 
    folder_name=None, summary="Extraction Service", tags="extract data, clip")
   

# analyze the service definition draft
analyzeMessages = arcpy.mapping.AnalyzeForSD(sddraft)

# stage and upload the service if the sddraft analysis did not contain errors
if analyzeMessages['errors'] == {}:
    # Execute StageService
    arcpy.StageService_server(sddraft, sd)
    # Execute UploadServiceDefinition
    upStatus = arcpy.UploadServiceDefinition_server(sd, connPath)
    print "Completed upload"
else: 
    # if the sddraft analysis contained errors, display them
    print analysis['errors']
