我正在开发一个需要在Windows事件日志中通知特定事件的程序。我不知道需要在NotifyChangeEventLog()函数中指定的参数。
以下是我一直在使用的代码:
import win32evtlog
server = 'localhost' # name of the target computer to get event logs
logtype = 'Application' # 'Application' # 'Security'
hand = win32evtlog.OpenEventLog(server,logtype)
flags =
win32evtlog.EVENTLOG_BACKWARDS_READ|win32evtlog.EVENTLOG_SEQUENTIAL_READ
total = win32evtlog.GetNumberOfEventLogRecords(hand)
print total
notify = win32evtlog.NotifyChangeEventLog(hand, 1)
我收到此错误:
notify = win32evtlog.NotifyChangeEventLog(hand,1)
Traceback(最近一次调用最后一次):
文件“”,第1行,in
notify = win32evtlog.NotifyChangeEventLog(hand,1)
错误:(6,'NotifyChangeEventLog','句柄无效。')
有什么参数?
您找到了第一个参数,它是打开事件日志的句柄。
根据[MS.Docs]: NotifyChangeEventLog function(win32evtlog.NotifyChangeEventLog
包裹):
hEvent
手动重置或自动重置事件对象的句柄。使用CreateEvent函数创建事件对象。
所以,你需要这样的东西。
code.朋友:
#!/usr/bin/env python3
import sys
import win32evtlog
import win32event
import win32api
import win32con
import msvcrt
def main():
server = None # "localhost" # name of the target computer to get event logs
source_type = "System" # "Application" # "Security"
h_log = win32evtlog.OpenEventLog(server, source_type)
flags = win32evtlog.EVENTLOG_BACKWARDS_READ | win32evtlog.EVENTLOG_SEQUENTIAL_READ
total = win32evtlog.GetNumberOfEventLogRecords(h_log)
print(total)
h_evt = win32event.CreateEvent(None, 1, 0, "evt0")
win32evtlog.NotifyChangeEventLog(h_log, h_evt)
print("Waiting for changes in the '{:s}' event log. Press a key to exit...".format(source_type))
while not msvcrt.kbhit():
wait_result = win32event.WaitForSingleObject(h_evt, 500)
if wait_result == win32con.WAIT_OBJECT_0:
print("The '{:s}' event log has been modified".format(source_type))
# Any processing goes here
elif wait_result == win32con.WAIT_ABANDONED:
print("Abandoned")
win32api.CloseHandle(h_evt)
win32evtlog.CloseEventLog(h_log)
if __name__ == "__main__":
print("Python {:s} on {:s}\n".format(sys.version, sys.platform))
main()
