如何使用Python创建Windows服务

Question

我编写了一个 python 脚本，它将作为 Windows 服务安装。下面是代码：

import datetime
import logging
from logging.handlers import RotatingFileHandler
import os
import time
from random import randint
import win32serviceutil
import win32service
import win32event
import servicemanager
import socket


def setup_logger(logger_name, log_file, level=logging.ERROR):
    log_formatter = logging.Formatter('%(asctime)s %(message)s')
    my_handler = RotatingFileHandler(log_file, maxBytes=100 * 1024 * 1024, backupCount=5)
    my_handler.setFormatter(log_formatter)
    my_handler.setLevel(level)
    l = logging.getLogger(logger_name)
    l.handlers[:] = []
    l.addHandler(my_handler)


curr_path = os.getcwd()
log_file = "F:\\Projects\\TestService\\logs\\application.log"
setup_logger('debug', log_file)
log = logging.getLogger('debug')

class AppServerSvc(win32serviceutil.ServiceFramework):
    _svc_name_ = "test_service"
    _svc_display_name_ = "Test Service"

    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self, args)
        self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)
        socket.setdefaulttimeout(60)
        self.isrunning = False

    def SvcStop(self):
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        win32event.SetEvent(self.hWaitStop)
        self.isrunning = False

    def SvcDoRun(self):
        servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,
                              servicemanager.PYS_SERVICE_STARTED,
                              (self._svc_name_, ''))
        self.isrunning = True
        self.main()

    def main(self):
        while self.isrunning:
            log.error("Running {}".format(randint(00, 99)))
            time.sleep(10)


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

我已运行命令python test_service.py install来安装服务并获得了正确的输出Installing service test_service Service installed。当我打开服务选项卡时，我可以看到那里列出了我的服务。当我单击启动服务时，出现以下错误：

谁能告诉我代码中有什么问题导致它无法启动服务。请帮忙。谢谢

更新：

我在调试模式下运行该服务cmd，看起来工作正常。但从服务选项卡来看，它不起作用并显示上述错误。

> python test_service.py debug
      Debugging service test_service - press Ctrl+C to stop.
      Info 0x40001002 - The test_service service has started.

启动服务时，出现同样的错误：

> python test_service.py start
     Starting service test_service
     Error starting service: The service did not respond to the start or control request in a timely fashion.

不知道为什么它没有运行，在调试模式下它运行良好。请帮忙。

任何遇到此问题的人，只需复制pywintypes36.dll

从Python36\Lib\site-packages\pywin32_system32

到Python36\Lib\site-packages\win32

有用的命令：

1. 安装服务：python app.py install

2. 卸载服务：python app.py remove

3. 启动服务：python app.py start

4. 更新服务：python app.py update
