Hello,
I am new to Python Window services development. I have small code below.
from datetime import datetime
import time
import sys
import os
import win32service
import win32serviceutil
import win32api
import win32con
class DemoService(win32serviceutil.ServiceFramework):
_svc_name_ = "DemoService"
_svc_display_name_ = "DemoService"
def __init__(self, args):
win32serviceutil.ServiceFramework.__init__(self, args)
self.isAlive = True
self.args = args
def SvcDoRun(self):
import servicemanager
while self.isAlive:
start_mail_check(args[2], args[3])
self.isAlive = False
def SvcStop(self):
import servicemanager
servicemanager.LogInfoMsg("ZetlConductorSvcs - Received stop signal")
self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
self.isAlive = False
def ctrlHandler(ctrlType):
return True
def start_mail_check(user_id=None, passwd=None):
if not user_id and not passwd:
servicemanager.LogInfoMsg("DemoService - Invalid argument passed.")
else:
#Go ahead to download the mails from configured mail server.
def main():
print ">>>", sys.argv, len(sys.argv)
if __name__ == '__main__':
win32api.SetConsoleCtrlHandler(ctrlHandler, True)
win32serviceutil.HandleCommandLine(DemoService, argv=sys.argv)
I use this script to run to download mails for different user_id and password
from configured mail server.
Generally i run this script as batch file which takes parameters like user_id
and password
python demo_svcs.py install
python demo_svcs.py start %user_id% %password%
At present in my code i am passing user_id and password as argv
"win32serviceutil.HandleCommandLine(DemoService, argv=sys.argv)"
which intern i am accessing these user_id and password in 'SvcDoRun' method
with 'args', i just wanted to know is this the correct approach or do we have flexibility
to overwrite 'SvcDoRun' method to get these 'user_id' and 'password' as kwd_args
and use these kwd_args in 'start_mail_check' method.
I want to run the same service with different user_id and password as command line args
for multiple users.
I gooled to find out examples with with parameters, but i am not lucky enough to find out.
Could any one suggest me move forward in this regard.
Thanks,
Pavi
