Python views folder permission groups and uses OS modules to operate folders

Mar 27, 2017 pm 04:26 PM

@It is recommended to map the network drive when operating the server server folder

import win32security
import ntsecuritycon as con

FILENAME = r'D:\tmp\acc_test' #File Folder path

sd = win32security.GetFileSecurity(FILENAME, win32security.DACL_SECURITY_INFORMATION)
dacl = sd.GetSecurityDescriptorDacl()

ace_count = dacl.GetAceCount() #Show users with folder permissions (Group) quantity
print('Ace count:', ace_count)

for i in range(0, ace_count):
rev, access, usersid = dacl.GetAce(i)
user, group, type = win32security.LookupAccountSid('', usersid)
print('User: {}/{}'.format(group, user), rev, access)
User: user (0 , 0) 1179817 #Only this folder, viewing permissions
User: admin (0, 0) 1245631 #Only this folder, modifying permissions
User: administrator (0, 3) 2032127 #This folder, sub Folder All permissions

#Delete folder permissions
Now you are able to read old ACEs and deleting old ones is quite simple:
for i in range(0, ace_count):
dacl.DeleteAce(0)

#Add privileges using add
And after that you can just add privileges by calling AddAccessAllowedAceEx() [MSDN]:
userx, domain, type = win32security.LookupAccountName ("", "your.user")
usery, domain, type = win32security.LookupAccountName ("", "other.user")

dacl.AddAccessAllowedAceEx(win32security. ACL_REVISION, 3, 2032127, userx) #Full control@middle 3 means that the permissions will be inherited by subsequent folders 0: No
dacl.AddAccessAllowedAceEx(win32security.ACL_REVISION, 3, 1179785, usery) #Read-only permissions

sd.SetSecurityDescriptorDacl(1, dacl, 0) #May not be necessary
win32security.SetFileSecurity(FILENAME, win32security.DACL_SECURITY_INFORMATION, sd)
I've taken numbers 3, 2032127 and 1179785 from the listing in first half of the script (before running the script I've set up privileges in Explorer->Right Click->Properties->Security->Advanced):


# #Example
# try:
# permit = '1179817'
# acegroup = 'Users'
# folder = 'Z:\\50.Test Folder\\01.2'
# sd = win32security.GetFileSecurity(folder, win32security.DACL_SECURITY_INFORMATION)
# dacl = sd.GetSecurityDescriptorDacl()
# user1, domain, type = win32security.LookupAccountName('', acegroup)

## permisson = int(permit)
# dacl.AddAccessAllowedAceEx(win32security.ACL_REVISION, 0, permisson, user1) #The 0 in the middle means that only the folder 3 represents this folder, the sub-file
# sd.SetSecurityDescriptorDacl(1 , dacl, 0) # may not be necessary
# win32security.SetFileSecurity(folder, win32security.DACL_SECURITY_INFORMATION, sd)
# except Exception as e:
# print(e)

# python's os module controls the folder
#import os
#import shutil

# try:
# os.mkdir(r'Z:\50.test folder\01.2') #New folder
# except Exception as e:
# print(e)

# try:
# os.rename(r'Z:\50.Test folder\01.2 ',r'Z:\50.Test Folder\01.3') #Rename the folder
# except Exception as e:
# print(e)

# try:
# shutil.rmtree(r'Z:/50.Test folder/01.3') ##Delete the named folder
# except Exception as e:
# Print(e)
PS. Call cmd control Folder

#Create folder
def createfolder(request):
folder=r'Z:/50 .Test folder/01.3'
result={}
try:
#Connect to the remote server using wmi
pythoncom.CoInitialize()
conn = wmi.WMI(computer='192.168 .0.1', user='user', password='user')
cmd_callbat=r"cmd.exe /c mkdir %s" % folder
conn.Win32_Process.Create(CommandLine=cmd_callbat) #Execute bat File
result['isSuccess']=True
result['message']=' Added successfully'
except Exception as e:
print(e)
result['isSuccess'] = False
result['message'] = 'Add failed'+e
response = HttpResponse()
response['Content-Type'] = "text/javascript"
response.write(json .dumps(result))
return response
