python - 如何按名称查找进程并使用 ctypes 终止进程？

Question

在 Windows 上，我想找到名为“exename.exe”的进程，然后将其终止。

我如何通过 ctypes 而不是任何其他第 3 方模块来做到这一点？

Answer 1

试试这个:

import sys, os.path, ctypes, ctypes.wintypes

Psapi = ctypes.WinDLL('Psapi.dll')
EnumProcesses = Psapi.EnumProcesses
EnumProcesses.restype = ctypes.wintypes.BOOL
GetProcessImageFileName = Psapi.GetProcessImageFileNameA
GetProcessImageFileName.restype = ctypes.wintypes.DWORD

Kernel32 = ctypes.WinDLL('kernel32.dll')
OpenProcess = Kernel32.OpenProcess
OpenProcess.restype = ctypes.wintypes.HANDLE
TerminateProcess = Kernel32.TerminateProcess
TerminateProcess.restype = ctypes.wintypes.BOOL
CloseHandle = Kernel32.CloseHandle

MAX_PATH = 260
PROCESS_TERMINATE = 0x0001
PROCESS_QUERY_INFORMATION = 0x0400

count = 32
while True:
    ProcessIds = (ctypes.wintypes.DWORD*count)()
    cb = ctypes.sizeof(ProcessIds)
    BytesReturned = ctypes.wintypes.DWORD()
    if EnumProcesses(ctypes.byref(ProcessIds), cb, ctypes.byref(BytesReturned)):
        if BytesReturned.value<cb:
            break
        else:
            count *= 2
    else:
        sys.exit("Call to EnumProcesses failed")

for index in range(BytesReturned.value / ctypes.sizeof(ctypes.wintypes.DWORD)):
    ProcessId = ProcessIds[index]
    hProcess = OpenProcess(PROCESS_TERMINATE | PROCESS_QUERY_INFORMATION, False, ProcessId)
    if hProcess:
        ImageFileName = (ctypes.c_char*MAX_PATH)()
        if GetProcessImageFileName(hProcess, ImageFileName, MAX_PATH)>0:
            filename = os.path.basename(ImageFileName.value)
            if filename == 'notepad.exe':
                TerminateProcess(hProcess, 1)
        CloseHandle(hProcess)
