What is the best way to map windows drives using P

Question

What is the best way to map a network share to a windows drive using Python? This share also requires a username and password.

Answer 1

Building off of @Anon's suggestion:

# Drive letter: M
# Shared drive path: \\shared\folder
# Username: user123
# Password: password
import subprocess

# Disconnect anything on M
subprocess.call(r'net use m: /del', shell=True)

# Connect to shared drive, use drive letter M
subprocess.call(r'net use m: \\shared\folder /user:user123 password', shell=True)

I prefer this simple approach, especially if all the information is static.

Answer 2

I had trouble getting this line to work:

win32wnet.WNetAddConnection2(win32netcon.RESOURCETYPE_DISK, drive, networkPath, None, user, password)

But was successful with this:

win32wnet.WNetAddConnection2(1, 'Z:', r'\UNCpath\share', None, 'login', 'password')

Answer 3

If you want to map the current login user, i think subprocess solve your problem. But is you want to control different mappings for different users, from a single master account. You could do this from the register of windows

The idea is to load the profile of a given user.

import win32api
import win32security
import win32profile
import win32netcon
import win32net
import win32netcon
import win32con

il = 'G'
m = '\\\\192.168.1.16\\my_share_folder'
usu = 'my_user'
cla = 'passwd'

#login the user
hUser = win32security.LogonUser(
       usu,
       None,
       cla,
       win32security.LOGON32_LOGON_NETWORK,
       win32security.LOGON32_PROVIDER_DEFAULT 
    )

#load the profile
hReg = win32profile.LoadUserProfile (
             hUser,  
             {"UserName" : usu}
            )

#alter the regedit entries of usu
win32api.RegCreateKey(hReg, "Network")
hkey = win32api.RegOpenKey(hReg, "Network\\", 0, win32con.KEY_ALL_ACCESS)
win32api.RegCreateKey(hkey, il)
hkey = win32api.RegOpenKey(hReg, "Network\\%s" % il, 0, win32con.KEY_ALL_ACCESS)
win32api.RegSetValueEx(hkey, "ConnectionType", 0, win32con.REG_DWORD, 1)
win32api.RegSetValueEx(hkey, "DeferFlags", 0, win32con.REG_DWORD, 4)
win32api.RegSetValueEx(hkey, "ProviderName", 0, win32con.REG_SZ, "Red de Microsoft Windows")
win32api.RegSetValueEx(hkey, "ProviderType", 0, win32con.REG_DWORD, 131072)
win32api.RegSetValueEx(hkey, "RemotePath", 0, win32con.REG_SZ, m)
win32api.RegSetValueEx(hkey, "UserName", 0, win32con.REG_DWORD, 0)

I'd go with IronPython and this article : Mapping a Drive Letter Programmatically. Or you could use the Win32 API directly.

Okay, Here's another method...

This one was after going through win32wnet. Let me know what you think...

def mapDrive(drive, networkPath, user, password, force=0):
    print networkPath
    if (os.path.exists(drive)):
        print drive, " Drive in use, trying to unmap..."
        if force:
            try:
                win32wnet.WNetCancelConnection2(drive, 1, 1)
                print drive, "successfully unmapped..."
            except:
                print drive, "Unmap failed, This might not be a network drive..."
                return -1
        else:
            print "Non-forcing call. Will not unmap..."
            return -1
    else:
        print drive, " drive is free..."
    if (os.path.exists(networkPath)):
        print networkPath, " is found..."
        print "Trying to map ", networkPath, " on to ", drive, " ....."
        try:
            win32wnet.WNetAddConnection2(win32netcon.RESOURCETYPE_DISK, drive, networkPath, None, user, password)
        except:
            print "Unexpected error..."
            return -1
        print "Mapping successful"
        return 1
    else:
        print "Network path unreachable..."
        return -1

And to unmap, just use....

def unmapDrive(drive, force=0):
    #Check if the drive is in use
    if (os.path.exists(drive)):
        print "drive in use, trying to unmap..."
        if force == 0:
            print "Executing un-forced call..."
        try:
            win32wnet.WNetCancelConnection2(drive, 1, force)
            print drive, "successfully unmapped..."
            return 1
        except:
            print "Unmap failed, try again..."
            return -1
    else:
        print drive, " Drive is already free..."
        return -1

Here are a couple links which show use of the win32net module that should provide the functionality you need.
