我想在这个例子中做点什么：Python - How to get the start/base address of a process? . 我和那个话题中的人有同样的问题，因为指针作弊引擎提供的是参考进程本身的基地址。
我环顾四周，看起来最好的解决方案是使用 ctypes 和 MODULEENTRY32 来存储进程的快照并分析它们的 modBaseAddr。
这是我当前的代码
import os.path, ctypes, ctypes.wintypes
from ctypes import *
from ctypes.wintypes import *
PROCESS_QUERY_INFORMATION = (0x0400)
PROCESS_VM_OPERATION = (0x0008)
PROCESS_VM_READ = (0x0010)
PROCESS_VM_WRITE = (0x0020)
TH32CS_SNAPMODULE = (0x00000008)
CreateToolhelp32Snapshot= ctypes.windll.kernel32.CreateToolhelp32Snapshot
Process32First = ctypes.windll.kernel32.Process32First
Process32Next = ctypes.windll.kernel32.Process32Next
Module32First = ctypes.windll.kernel32.Module32First
Module32Next = ctypes.windll.kernel32.Module32Next
GetLastError = ctypes.windll.kernel32.GetLastError
OpenProcess = ctypes.windll.kernel32.OpenProcess
GetPriorityClass = ctypes.windll.kernel32.GetPriorityClass
CloseHandle = ctypes.windll.kernel32.CloseHandle
class MODULEENTRY32(Structure):
_fields_ = [ ( 'dwSize' , DWORD ) ,
( 'th32ModuleID' , DWORD ),
( 'th32ProcessID' , DWORD ),
( 'GlblcntUsage' , DWORD ),
( 'ProccntUsage' , DWORD ) ,
( 'modBaseAddr' , POINTER(BYTE)) ,
( 'modBaseSize' , DWORD ) ,
( 'hModule' , HMODULE ) ,
( 'szModule' , c_char * 256 ),
( 'szExePath' , c_char * 260 ) ]
def GetBaseAddr(ProcId, ProcName):
me32 = MODULEENTRY32()
me32.dwSize = sizeof(me32)
hSnapshot = CreateToolhelp32Snapshot( TH32CS_SNAPMODULE, ProcId)
if GetLastError() != 0:
CloseHandle(hSnapshot)
print 'Handle Error %s' % WinError()
return 'Error'
else:
if Module32First(hSnapshot, byref(me32)):
if me32.szModule == ProcName:
CloseHandle(hSnapshot)
return id(me32.modBaseAddr)
else:
Module32Next(hSnapshot, byref(me32))
while int(GetLastError())!= 18:
if me32.szModule == ProcName:
CloseHandle(hSnapshot)
return id(me32.modBaseAddr)
else:
Module32Next(hSnapshot, byref(me32))
CloseHandle(hSnapshot)
print 'Couldn\'t find Process with name %s' % ProcName
else:
print 'Module32First is False %s' % WinError()
CloseHandle(hSnapshot)
def GetProcessIdByName( pName):
if pName.endswith('.exe'):
pass
else:
pName = pName+'.exe'
ProcessIds, BytesReturned = EnumProcesses()
for index in range(BytesReturned / ctypes.sizeof(ctypes.wintypes.DWORD)):
ProcessId = ProcessIds[index]
hProcess = ctypes.windll.kernel32.OpenProcess(PROCESS_QUERY_INFORMATION, False, ProcessId)
if hProcess:
ImageFileName = (ctypes.c_char*MAX_PATH)()
if ctypes.windll.psapi.GetProcessImageFileNameA(hProcess, ImageFileName, MAX_PATH)>0:
filename = os.path.basename(ImageFileName.value)
if filename == pName:
return ProcessId
CloseHandle(hProcess)
def EnumProcesses():
count = 32
while True:
ProcessIds = (ctypes.wintypes.DWORD*count)()
cb = ctypes.sizeof(ProcessIds)
BytesReturned = ctypes.wintypes.DWORD()
if ctypes.windll.Psapi.EnumProcesses(ctypes.byref(ProcessIds), cb, ctypes.byref(BytesReturned)):
if BytesReturned.value<cb:
return ProcessIds, BytesReturned.value
break
else:
count *= 2
else:
return None
if __name__ == '__main__':
ProcId = GetProcessIdByName('RocketLeague.exe')
#print ProcId
print hex(GetBaseAddr(ProcId, 'RocketLeague.exe'))
#print hex(GetBaseAddr(8252,'RocketLeague.exe'))
现在我对内存的理解并不是最好的，但我认为在程序运行时基地址应该是静态的。当我运行这段代码时，每次运行时我得到的 ModBaseAddr 都会发生变化。我遇到的另一个奇怪的问题是，如果没有该 print ProcId 语句，运行程序会从第 41 行返回 ERROR_ACCESS_DENIED（错误 5）（这与我假设的 CreateToolhelp32Snapshot 函数有关，因为我在计算机上拥有管理员权限）。但是，使用 print 语句，程序每次都会运行给我一个不同的 ModBaseAddr。如果我手动输入 GetBaseAddr 函数 ProcessId 它也可以在没有打印语句的情况下工作，但是，它每次都会给我一个随机地址。如果有人可以为我提供任何帮助或为我指明正确的方向，我
