arcpy连接 sde连接串

# sde = "E:\\saae-api\\tools\\Connection_to_10.45.204.118.sde" #OK
# sde = r'E:\saae-api\tools\Connection_to_10.45.204.118.sde' #OK
# sde = r'Connection_to_10.45.204.118.sde' #这样不能访问到连接
# sde = "数据库连接\\Connection to 10.45.204.118.sde'" #这样也不能
# sde="C:\\Users\\yansc007\\AppData\\Roaming\\ESRI\\Desktop10.8\\ArcCatalog\\Connection to 10.45.204.118.sde" #OK
sde=r'C:\Users\yansc007\AppData\Roaming\ESRI\Desktop10.8\ArcCatalog\Connection to 10.45.204.118.sde' #OK

是需要再加哪一句？

补充：2021-10-15

经测试远程vpn访问sde无问题

#coding=utf-8
import arcpy

# arcpy.env.workspace=r'E:\xxx\1213\data2000.gdb'

sde=r'C:\Users\xxx\AppData\Roaming\ESRI\Desktop10.8\ArcCatalog\105hz1-rd01.sde'
arcpy.env.workspace=sde

dss=arcpy.ListDatasets()
for ds in dss:
    print(ds)

print('over')

arcpy连接 sde连接串
