Question

我已经通过pywin32构建了一个Windows服务应用程序。我无法在目录'％LOCALAPPDATA％'中创建任何文件或目录。我认为导致这个问题的原因可能是我的应用程序没有足够的权限来创建文件，但我不太确定。我是Windows编程的初学者。我该如何解决这个问题？

这是我的代码：

import traceback
import os
import sys

import win32serviceutil
import win32security
import win32api
import win32service
import win32event
import win32file

class newsLauncher(win32serviceutil.ServiceFramework):

    _svc_name_ = 'Test_service'
    _svc_display_name_ = 'Test for service'


    def __init__(self, *args):
        win32serviceutil.ServiceFramework.__init__(self, *args)
        self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)


    def log(self, msg):
        import servicemanager
        servicemanager.LogInfoMsg(str(msg))
        def sleep(self, sec):
            win32api.Sleep(sec*1000, True)


    def SvcDoRun(self):
        self.ReportServiceStatus(win32service.SERVICE_START_PENDING)
        try:
            cwd = os.path.join(os.environ['LOCALAPPDATA'], "test_service")
            os.mkdir(cwd)
            os.chdir(cwd)

            open("test.log", 'w').write("success create file.")

            self.ReportServiceStatus(win32service.SERVICE_RUNNING)

            win32event.WaitForSingleObject(self.hWaitStop, win32event.INFINITE)
            self.ReportServiceStatus(win32service.SERVICE_STOPPED)
        except Exception as e:
            self.log('Exception: %s' % e)
            self.log('line %d' % traceback.tb_lineno(sys.exc_info()[2]))
            self.SvcStop()
            self.ReportServiceStatus(win32service.SERVICE_STOPPED)


    def SvcStop(self):
        self.log("in stop")

        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)

        win32event.SetEvent(self.hWaitStop)
        self.log("stoped")


if __name__ == '__main__':
    win32serviceutil.HandleCommandLine(newsLauncher)

使用PyWin32创建Windows服务，但它无法在％LOCALAPPDATA％中创建文件
