使用python获取window注册表值的方法

提供regfullpath的方法，可以自行封装个regpath的函数
import logging
import pywintypes

import win32api
import win32con

def getValue(strKeyPath, intAccessMask, strValueName, default=None):

    if strKeyPath[0] == '\\':

        strKeyPath = strKeyPath[1:]

    strRoot, strKey = strKeyPath.split('\\', 1)

    if strRoot not in g_dicKeyRoot:

        raise KeyError(strRoot)

    intRoot = g_dicKeyRoot[strRoot]

    if intAccessMask == None:

        intAccessMask = win32con.KEY_QUERY_VALUE | win32con.KEY_ENUMERATE_SUB_KEYS | win32con.KEY_NOTIFY

    h = win32api.RegOpenKeyEx(intRoot, strKey, 0, intAccessMask)

    try:

        value, vType = win32api.RegQueryValueEx(h, strValueName)

    except pywintypes.error as e:

        if str(e.args[0]) == '2':  # value name doesn't exist

            if strValueName == '':

                return None, win32con.REG_NONE

            if default != None:

                return default, None

        raise

    return value, vType

def actGetRegKey(strRegKeyPath, strKeyName):

    '''

    @param strRegKeyPath: Specify registry key path. Ex. r"HKEY_LOCAL_MACHINE\SOFTWARE\test123"

    @param strKeyName: Specify registry key name. Ex. "VirusCount"

    @return: strKeyValue[0] -> key value

    @example: actGetRegKey(r"HKEY_LOCAL_MACHINE\SOFTWARE\test123","VirusCount")

    '''

    try:

        intAccessMask = win32con.KEY_QUERY_VALUE | win32con.KEY_ENUMERATE_SUB_KEYS | win32con.KEY_NOTIFY

        strKeyValue = getValue(strRegKeyPath, intAccessMask, strKeyName)

        logging.debug(

            'GetRegKey success, path %s, keyName %s , keyValue %s' % (strRegKeyPath, strKeyName, strKeyValue))

        return strKeyValue[0]

    except pywintypes.error as e:

        if 'Access is denied' in str(e):

            logging.info(

                'Reading regkey %s %s access is denied, change way to KEY_READ' % (strRegKeyPath, strKeyName))

            strKeyValue = getValue(strRegKeyPath, win32con.KEY_READ, strKeyName)

            logging.debug(

                'GetRegKey success, path %s, keyName %s , keyValue %s' % (strRegKeyPath, strKeyName, strKeyValue))

            return strKeyValue[0]

def GetRegistryValuebyFullPath(fullregpath, regkeyname):

    try:

        logging.info("full registry path: %s" % fullregpath)

        registryValue = actGetRegKey(fullregpath, regkeyname)

        logging.info("registryValue: %s" % registryValue)

        return registryValue

    except pywintypes.error as e:

        logging.error('GetRegistryValue Error! %s' % str(e))
