以arcgispro的python脚本为例在arcgispro自带的python窗口下运行python脚本
需求:
将arcgispro的.aprx项目包中gdb的数据源路径更换为sde数据源路径。
示例数据:
演示过程:
方式一:脚本中指定好相关参数设置
import arcpy import json import sys import os import argparse import re result = "" jsontext = {'success': {}, 'msg': ''} def checksavedaprxdatasource(output_aprx_path, mapname, targetdb): check_result = true desc = arcpy.describe(targetdb) saved_aprx = arcpy.mp.arcgisproject(output_aprx_path) for saved_map in saved_aprx.listmaps(): if saved_map.name == mapname: for lyr in saved_map.listlayers(): if lyr.isfeaturelayer: # print(lyr.connectionproperties) if lyr.connectionproperties['workspace_factory'].upper() == 'sde'.upper( ) and lyr.connectionproperties['connection_info']['instance'] == desc.connectionproperties.instance: pass else: check_result = false return check_result if __name__ == '__main__': try: # linux # aprxpath = str(sys.argv[1]) # mapname = str(sys.argv[2]) # sourcedb = str(sys.argv[3]) # targetdb = str(sys.argv[4]) # output_aprx_path = str(sys.argv[5]) # local pc aprxpath = r'd:\rvt\testaprx\testaprx.aprx' mapname = 'map' sourcedb = r'd:\rvt\testaprx\data.gdb' targetdb = r'd:\rvt\testaprx\testsde.sde' output_aprx_path = r'd:\rvt\testaprx\output\export5.aprx' aprx = arcpy.mp.arcgisproject(aprxpath) for m in aprx.listmaps(): if m.name == mapname: m.updateconnectionproperties(sourcedb, targetdb) if os.path.exists(output_aprx_path): os.remove(output_aprx_path) aprx.saveacopy(output_aprx_path) checkresult = checksavedaprxdatasource( output_aprx_path, mapname, targetdb) if checkresult: jsontext['success'] = true result = json.dumps(jsontext) sys.stdout.write(result) else: jsontext['success'] = false jsontext['msg'] = 'failed to replace data source' result = json.dumps(jsontext) sys.stdout.write(result) except exception as e: jsontext['success'] = false jsontext['msg'] = e.args result = json.dumps(jsontext) sys.stdout.write(result)
方式二:使用sys.argv[ ]的形式设置相关参数
(arcgispro-py3) d:\rvt\testaprx>python test.py d:\rvt\testaprx\testaprx.aprx map d:\rvt\testaprx\data.gdb d:\rvt\testaprx\testsde.sde d:\rvt\testaprx\output\export5.aprx
import arcpy import json import sys import os import argparse import re result = "" jsontext = {'success': {}, 'msg': ''} def checksavedaprxdatasource(output_aprx_path, mapname, targetdb): check_result = true desc = arcpy.describe(targetdb) saved_aprx = arcpy.mp.arcgisproject(output_aprx_path) for saved_map in saved_aprx.listmaps(): if saved_map.name == mapname: for lyr in saved_map.listlayers(): if lyr.isfeaturelayer: # print(lyr.connectionproperties) if lyr.connectionproperties['workspace_factory'].upper() == 'sde'.upper( ) and lyr.connectionproperties['connection_info']['instance'] == desc.connectionproperties.instance: pass else: check_result = false return check_result if __name__ == '__main__': try: # linux aprxpath = str(sys.argv[1]) mapname = str(sys.argv[2]) sourcedb = str(sys.argv[3]) targetdb = str(sys.argv[4]) output_aprx_path = str(sys.argv[5]) print("aprx路径: "+aprxpath) print("地图视图的名称: "+mapname) print("当前的数据源路径: "+sourcedb) print("目标数据源路径: "+targetdb) print("aprx另存为路径: "+output_aprx_path) # local pc # aprxpath = r'd:\rvt\testaprx\testaprx.aprx' # mapname = 'map' # sourcedb = r'd:\rvt\testaprx\data.gdb' # targetdb = r'd:\rvt\testaprx\testsde.sde' # output_aprx_path = r'd:\rvt\testaprx\output\export5.aprx' aprx = arcpy.mp.arcgisproject(aprxpath) for m in aprx.listmaps(): if m.name == mapname: m.updateconnectionproperties(sourcedb, targetdb) if os.path.exists(output_aprx_path): os.remove(output_aprx_path) aprx.saveacopy(output_aprx_path) checkresult = checksavedaprxdatasource( output_aprx_path, mapname, targetdb) if checkresult: jsontext['success'] = true result = json.dumps(jsontext) sys.stdout.write(result) else: jsontext['success'] = false jsontext['msg'] = 'failed to replace data source' result = json.dumps(jsontext) sys.stdout.write(result) except exception as e: jsontext['success'] = false jsontext['msg'] = e.args result = json.dumps(jsontext) sys.stdout.write(result)
