使用 python 3.5 的 urllib 上的 SMb 处理程序

Question

我正在尝试从 Windows 共享文件夹中获取一些文件，在 Ubuntu 操作系统上运行 python3.5。由于 urllib2 在 python3 上不可用，我有这个简单的代码：

目录 = 'smb://user:passw@xxx.xxx.x.xx/shared_folder/' 对于符号中的符号：

   path = dir+symbol+'.csv'
   director = urllib.request.build_opener(SMBHandler)
   fh = director.open(path)

   # ..... do some stuff

   fh.close()

符号是当前存在的n个文件的列表。该代码适用于符号中的前 2 个元素，但由于某种原因，在 2 个循环之后我收到此错误
