Question

我已阅读How to create a service in Python in Windows和opening another program through windows service using python。

现在我有以下代码：

# server.py
class ServerManager(win32serviceutil.ServiceFramework):
    _svc_name_ = 'test'
    _svc_display_name_ = 'test_display'

    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self, args)
        self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)
        self._poll_intvl = 20

    def SvcDoRun(self):
        servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,
                              servicemanager.PYS_SERVICE_STARTED,
                              (self._svc_name_, ''))
        # self.timeout = 100
        while 1:
            rc = win32event.WaitForSingleObject(self.hWaitStop, win32event.INFINITE)
            if rc == win32event.WAIT_OBJECT_0:
                break
            else:
                import config
                output_directory = config.get_prop('dump.path')

                with open(r'e:\time.txt','a') as f:
                    f.write('%s %s'%(str(output_directory), ''))
                time.sleep(self._poll_intvl)
        return


    def SvcStop(self):
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        win32event.SetEvent(self.hWaitStop)
        return

和其他代码：

# config.py
import ConfigParser
import os

def _read_config(configPath):
    cd = {}
    cf = ConfigParser.ConfigParser()
    cf.read(configPath)
    sessions = cf.sections()
    for session in sessions:
        options = cf.options(session)
        for option in options:
            key = session + "." + option
            value = cf.get(session, option)
            cd[key.lower()] = value
    return cd

g_propDict = {}
def get_prop(key):
    global g_propDict
    if key not in g_propDict:
        propFilePath = os.path.join(os.getcwd(), 'config.ini')
        g_propDict = _read_config(propFilePath)

    if key in g_propDict:
        return g_propDict[key]
    return ''

现在，我的问题output_directory = config.get_prop('dump.path') SvcDoRun未运行，为什么？如果我在其他pyfile中使用它，它可以运行。

Answer 1

现在我已经解决了这个问题，原因是os.getcwd()在函数C:\Python27\Lib\site-packages\win32中返回SvcDoRun。

为什么不能在win32serviceutil.ServiceFramework的SvcDoRun中运行我的函数？
