我正在尝试用我们的新 sde 路径“替换数据源”。我在 Arc10.2 中使用 v2.7。我们有多个直接连接路径名称和一个将服务器从使用 Oracle 更改为 Sql Server 的服务连接。我的代码在打印语句中一直有效，但随后出现错误消息“无法保存 ACopy，请检查我的权限”。请让我知道我是否走在正确的轨道上，将所有各种连接名称放入一个列表中，然后按照我编写的方式遍历它们。此外，我已经尝试了 mxd.saveACopy 和 del mxd 的所有缩进，但两周后似乎没有任何效果，所以我想我终于要请教一些地理极客的智慧了！

Code:

导入 arcpy, os, glob arcpy.env.workspace = "C:\Users\kmetivier\Documents\BrokenPaths\Folder5"

对于根目录、子文件夹、>os.walk(r"C:\Users\kmetivier\Documents\BrokenPaths\Folder5") 中的文件：

for filename in files:
  fullpath = os.path.join(root, filename)
   basename, extension = os.path.splitext(fullpath)
   if extension.lower() == ".mxd":
       print "------------------------------"
       print filename
       #open the map document
       mxd = arcpy.mapping.MapDocument(fullpath)
       #get all the layers
       for lyr in arcpy.mapping.ListLayers(mxd):
           #get the source from the layer
           if lyr.supports("datasource"):
               pathList = ["Database Connections\PWDB.arvada.org.sde","Database >Connections\GIS - PWDB.sde","Database Connections\PROD - GIS.sde","Database Connections\DC >- PROD - GIS.sde","Database Connections\GIS to SDE1.sde"]
               print "%s -> %s" % (lyr, pathList[0])
               basename, extension = os.path.splitext (pathList[0])
               if extension.lower() == ".sde":
                   #NEW SOURCE
                   datapath = r"Database Connections\GEODATA - GIS.sde"
                   #overwrite the old path
                   lyr.replaceDataSource(datapath, "SDE_WORKSPACE", "")
                   print "replaced " + pathList[0] + " with " + datapath
                   print "---------finished " + filename
               mxd.saveACopy(filename +"_2")
           del mxd

        for lyr in arcpy.mapping.ListLayers(mxd):
           if lyr.supports("SERVICEPROPERTIES"):
               pathList1= r"(PWDB.arvada.org, 5151, {sde1}, {Database_authentication}, >{GDS}, {""}, {save_username_password}, {version}, {save_version_info}"
               servProp = lyr.serviceProperties
               print "Layer name:" + lyr.name
               print "-----------------------------------------------------"
               if lyr.serviceProperties["ServiceType"] != "SDE":
                   print "Service Type: " + servProp.get('ServiceType', 'N/A')
                   print "    URL:         " + servProp.get('URL', 'N/A')

                   print "    Password:    " + servProp.get('Password', 'N/A')
                   print ""
                   if extension.lower() == ".sde":
                       #This is the NEW SOURCE that you want to point to
                       datapath1 = r"Database Connections\GEODATA - GIS.sde"
                       #replace the old path wih the new
                       lyr.replaceDataSource(pathList1, "SDE_WORKSPACE", "")
                       print "replaced " + pathList1 + " with " + datapath1
