pydbg 64位enumerate_processes（）返回空列表

Question

我使用的是從此處下載的pydbg二進制文件： http ://www.lfd.uci.edu/~gohlke/pythonlibs/#pydbg，如先前答案中所建議。

我可以將32位版本與32位Python解釋器一起使用，但不能使64位版本與64位Python一起使用。 enumerate_processes()始終返回一個空列表。我在做錯什么嗎？

測試代碼：

import pydbg

if __name__ == "__main__":
    print(pydbg.pydbg().enumerate_processes())

32位工作：

>C:\Python27-32\python-32bit.exe
Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:19:22) [MSC v.1500 32 bit (Intel)] on win32
...
>C:\Python27-32\python-32bit.exe pydbg_test.py
[(0L, '[System Process]'), (4L, 'System'), <redacted for brevity>]

64位給出一個空列表：

>python
Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:24:40) [MSC v.1500 64 bit (AMD64)] on win32
...
>python pydbg_test.py

Pydbg定義PROCESSENTRY32結構錯誤。

最好使用諸如psutil之類的維護包或直接使用ctypes，例如：

from ctypes import windll, Structure, c_char, sizeof
from ctypes.wintypes import BOOL, HANDLE, DWORD, LONG, ULONG, POINTER

class PROCESSENTRY32(Structure):
    _fields_ = [
        ('dwSize', DWORD),
        ('cntUsage', DWORD),
        ('th32ProcessID', DWORD),
        ('th32DefaultHeapID', POINTER(ULONG)),
        ('th32ModuleID', DWORD),
        ('cntThreads', DWORD),
        ('th32ParentProcessID', DWORD),
        ('pcPriClassBase', LONG),
        ('dwFlags', DWORD),
        ('szExeFile', c_char * 260),
    ]

windll.kernel32.CreateToolhelp32Snapshot.argtypes = [DWORD, DWORD]
windll.kernel32.CreateToolhelp32Snapshot.restype = HANDLE
windll.kernel32.Process32First.argtypes = [HANDLE, POINTER(PROCESSENTRY32)]
windll.kernel32.Process32First.restype = BOOL
windll.kernel32.Process32Next.argtypes = [HANDLE, POINTER(PROCESSENTRY32)]
windll.kernel32.Process32Next.restype = BOOL
windll.kernel32.CloseHandle.argtypes = [HANDLE]
windll.kernel32.CloseHandle.restype = BOOL

pe = PROCESSENTRY32()
pe.dwSize = sizeof(PROCESSENTRY32)

snapshot = windll.kernel32.CreateToolhelp32Snapshot(2, 0)
found_proc = windll.kernel32.Process32First(snapshot, pe)
while found_proc:
    print(pe.th32ProcessID, pe.szExeFile)
    found_proc = windll.kernel32.Process32Next(snapshot, pe)

windll.kernel32.CloseHandle(snapshot)
