python kill process in windows (转)

本篇Python语言源码为：如何在windows平台下如何用Python杀进程的方法。主要的思路是在Python程序设置一个timeout，条件是一定时间内，如果这个程序没有返回，那么执行“杀掉这个这个新开的进程”。这就是我大概的思路，大家也可以自由发挥用你们的方法来杀进程。

如下就是我用Python杀进程的方法（windows）源码：需要用到ctypes、sys两个方法模块

import ctypes
import sys

TH32CS_SNAPPROCESS = 0x00000002

class PROCESSENTRY32(ctypes.Structure):
     _fields_ = [("dwSize", ctypes.c_ulong),
                 ("cntUsage", ctypes.c_ulong),
                 ("th32ProcessID", ctypes.c_ulong),
                 ("th32DefaultHeapID", ctypes.c_ulong),
                 ("th32ModuleID", ctypes.c_ulong),
                 ("cntThreads", ctypes.c_ulong),
                 ("th32ParentProcessID", ctypes.c_ulong),
                 ("pcPriClassBase", ctypes.c_ulong),
                 ("dwFlags", ctypes.c_ulong),
                 ("szExeFile", ctypes.c_char * 260)]

def getProcList():
    CreateToolhelp32Snapshot = ctypes.windll.kernel32.CreateToolhelp32Snapshot
    Process32First = ctypes.windll.kernel32.Process32First
    Process32Next = ctypes.windll.kernel32.Process32Next
    CloseHandle = ctypes.windll.kernel32.CloseHandle
    hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0)
    pe32 = PROCESSENTRY32()
    pe32.dwSize = ctypes.sizeof(PROCESSENTRY32)

    if Process32First(hProcessSnap,ctypes.byref(pe32)) == False:
        print >> sys.stderr, "Failed getting first process."
        return

    while True:
        yield pe32
        if Process32Next(hProcessSnap,ctypes.byref(pe32)) == False:
            break
    CloseHandle(hProcessSnap)

def getChildPid(pid):

    procList = getProcList()

    for proc in procList:

        if proc.th32ParentProcessID == pid:
            yield proc.th32ProcessID

def killPid(pid):

    childList = getChildPid(pid)

    for childPid in childList:
        killPid(childPid)

    handle = ctypes.windll.kernel32.OpenProcess(1, False, pid)

    ctypes.windll.kernel32.TerminateProcess(handle,0)


if __name__ =='__main__':

    args = sys.argv

    if len(args) >1 :
        pid = int(args[1])
        killPid(pid)

    else:
        procList = getProcList()
        for proc in procList:
            print proc.szExeFile+'  '+str(proc.th32ParentProcessID) + '  '+str(proc.th32ProcessID)

另一個例子，使用了winproc模塊：

import subprocess
import time
import winproc

timeout = 2

process = subprocess.Popen("cmd /k ping localhost -t",shell = True)

start = int(time.time())

while process.poll()==None:

    now = int(time.time())

    if int (now - start) >timeout:
        pid = process.pid
        break

winproc.killPid(pid)

print "End"

网上还有好多关于用Python语言杀进程的方法，但都不是太完整。希望我的这个源码能帮到有这方面需求的朋友们。
