SMbHandler Class
================

The SMBHandler class provides support for "smb://" URLs in the `urllib2 <http://docs.python.org/library/urllib2.html>`_ python package.

Notes
-----
* The host component of the URL must be one of the following:

  * A fully-qualified hostname that can be resolved by your local DNS service. Example: myserver.test.com
  * An IP address. Example: 192.168.1.1
  * A comma-separated string "<NBName>,<IP>" where *<NBName>* is the Windows/NetBIOS machine name for remote SMB service, and *<IP>* is the service's IP address. Example: MYSERVER,192.168.1.1

* The first component of the path in the URL points to the name of the shared folder.
  Subsequent path components will point to the directory/folder of the file.
* You can retrieve and upload files, but you cannot delete files/folders or create folders.
  In uploads, if the parent folders do not exist, an *urllib2.URLError* will be raised.

Example

The following code snippet illustrates file retrieval with Python 2.::

    # -*- coding: utf-8 -*-
    import urllib2
    from smb.SMBHandler import SMBHandler

    director = urllib2.build_opener(SMBHandler)
    fh = director.open('smb://myuserID:mypassword@192.168.1.1/sharedfolder/rfc1001.txt')

    # Process fh like a file-like object and then close it.
    fh.close()

    # For paths/files with unicode characters, simply pass in the URL as an unicode string
    fh2 = director.open(u'smb://myuserID:mypassword@192.168.1.1/sharedfolder/测试文件夹/垃圾文件.dat')

    # Process fh2 like a file-like object and then close it.
    fh2.close()

The following code snippet illustrates file upload with Python 2. You need to provide a file-like object for the *data* parameter in the *open()* method::

    import urllib2
    from smb.SMBHandler import SMBHandler

    file_fh = open('local_file.dat', 'rb')

    director = urllib2.build_opener(SMBHandler)
    fh = director.open('smb://myuserID:mypassword@192.168.1.1/sharedfolder/upload_file.dat', data = file_fh)

    # Reading from fh will only return an empty string
    fh.close()


The following code snippet illustrates file retrieval with Python 3.::

    import urllib
    from smb.SMBHandler import SMBHandler

    director = urllib.request.build_opener(SMBHandler)
    fh = director.open('smb://myuserID:mypassword@192.168.1.1/sharedfolder/rfc1001.txt')

    # Process fh like a file-like object and then close it.
    fh.close()

    # For paths/files with unicode characters, simply pass in the URL as an unicode string
    fh2 = director.open(u'smb://myuserID:mypassword@192.168.1.1/sharedfolder/测试文件夹/垃圾文件.dat')

    # Process fh2 like a file-like object and then close it.
    fh2.close()

The following code snippet illustrates file upload with Python 3. You need to provide a file-like object for the *data* parameter in the *open()* method::

    import urllib
    from smb.SMBHandler import SMBHandler

    file_fh = open('local_file.dat', 'rb')

    director = urllib.request.build_opener(SMBHandler)
    fh = director.open('smb://myuserID:mypassword@192.168.1.1/sharedfolder/upload_file.dat', data = file_fh)

    # Reading from fh will only return an empty string
    fh.close()
