# SMbHandler Class

The SMBHandler class provides support for “smb://” URLs in the urllib2 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()
