Windows 的 Python 服务有几个问题

Question

我已经检查了至少几十个与我相似的案例，但仍然没有找到解决方案，我希望有人能给出一些启示，我一定有什么遗漏的。

我正在使用 Python3.6 创建一个 Windows 服务，该服务必须运行一个 .exe 文件，如果它不是运行ning。这是 .py:

import win32service
import win32serviceutil
import win32api
import win32con
import win32event
import win32evtlogutil
import psutil
import subprocess
import os, sys, string, time
import servicemanager


class SLAAgent (win32serviceutil.ServiceFramework):
    _svc_name_ = "SLAAgent"
    _svc_display_name_ = "SLAAgent"

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

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

    def SvcDoRun(self):
        self.ReportServiceStatus(win32service.SERVICE_START_PENDING)
        self.ReportServiceStatus(win32service.SERVICE_RUNNING)
        servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,servicemanager.PYS_SERVICE_STARTED,(self._svc_name_, ''))
        self._logger.info("Service Is Starting")
        main(self)

    def main(self):
        while self.isAlive:
            rc = win32event.WaitForSingleObject(self.hWaitStop, self.timeout)
            # Check to see if self.hWaitStop happened
            if rc == win32event.WAIT_OBJECT_0:
                servicemanager.LogInfoMsg("SLAAService has stopped")  #For Event Log
                break
            else:
                try:
                    s = subprocess.check_output('tasklist', shell=True)
                    if "SLA_Client.exe" in s:
                        pass
                    else:
                        pass
                        #execfile("SLA_Client.exe") #Execute the script
                except:
                    pass

if __name__ == '__main__':
    if len(sys.argv) == 1:
        servicemanager.Initialize()
        servicemanager.PrepareToHostSingle(SLAAgent)
        servicemanager.StartServiceCtrlDispatcher()
    else:
        win32serviceutil.HandleCommandLine(SLAAgent)

我已经安装了 pywin32 包，将它们添加到 PATH 中，因为它在几个解决方案中被建议，并且还将 .dll 从 pywin32_system32 复制到 win32

环境变量

事件查看器错误

每次我运行时事件查看器都会打印此错误，无论是 python service.py 还是 python service.py 启动，控制台也会打印此错误:

python SLA_Agent.py
Traceback (most recent call last):
  File "SLA_Agent.py", line 56, in <module>
    servicemanager.StartServiceCtrlDispatcher()
pywintypes.error: (1063, 'StartServiceCtrlDispatcher', 'The service process 
could not connect to the service controller.')

尝试从“服务”工具启动服务时，会弹出此错误。我也看到了另一个错误，关于服务没有及时响应的错误。

我试过用pyinstaller和nuitka编译，错误都是一样的。我不确定如何继续，我已经更改了代码以适应我使用 google 和 SO 找到的示例和解决方案，并且对方法和原因知之甚少。

如果有人以前遇到过这些问题，我将非常感谢您的意见，到目前为止其他答案对我没有帮助。

后期编辑：修复了代码缩进

Answer 1

这最终对我有用，除了代码上的差异我没有做任何特别的事情，经过几次尝试我不得不使用 pyinstaller 和运行 service.exe install 编译问题。有一些人们可能不需要的额外日志行，但在调试和测试时它们派上用场了。

非常感谢所有留下评论的人，他们非常有帮助，没有你们就不可能完成<3
