python如何打开project

python如何打开project？

将arcgispro的.aprx项目包中gdb的数据源路径更换为sde数据源路径。

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)
