我见过很多人都为此苦苦挣扎 - 我也遇到了问题。如果有人可以帮助使 CherryPy 服务示例正常工作，那将是一个很大的帮助。解释这些问题将不胜感激。

作为 Windows 服务的 CherryPy 示例位于:CherryPy Wiki .我正在努力让它发挥作用。这是我的代码:

"""
The most basic (working) CherryPy 3.0 Windows service possible.
Requires Mark Hammond's pywin32 package.
"""

import cherrypy
import win32serviceutil
import win32service
import win32event
import servicemanager

class HelloWorld:
    """ Sample request handler class. """

    def index(self):
        return "Hello world!"
    index.exposed = True


class MyService(win32serviceutil.ServiceFramework):
    """NT Service."""

    _svc_name_ = "CherryPyService"
    _svc_display_name_ = "CherryPy Service"

    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self, args)
        # create an event that SvcDoRun can wait on and SvcStop
        # can set.
        self.stop_event = win32event.CreateEvent(None, 0, 0, None)

    def SvcDoRun(self):
        self.ReportServiceStatus(win32service.SERVICE_START_PENDING)
        servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,
                              servicemanager.PYS_SERVICE_STARTED,
                              (self._svc_name_,''))

        cherrypy.tree.mount(HelloWorld(), '/')

        # in practice, you will want to specify a value for
        # log.error_file below or in your config file.  If you
        # use a config file, be sure to use an absolute path to
        # it, as you can't be assured what path your service
        # will run in.
        cherrypy.config.update({
            'global':{
                'engine.autoreload.on': False,
                'log.screen': False,
                'log.error_file': 'c:\\MG\\temp\\CherryPy_Sample_Service.log',
                'engine.SIGHUP': None,
                'engine.SIGTERM': None
                }
            })
        # set blocking=False so that start() does not block
        cherrypy.server.quickstart()
        cherrypy.engine.start(blocking=False)
        # now, block until our event is set...
        win32event.WaitForSingleObject(self.stop_event, win32event.INFINITE)
        self.ReportServiceStatus(win32service.SERVICE_RUNNING)

    def SvcStop(self):
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        cherrypy.server.stop()
        win32event.SetEvent(self.stop_event)

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

以上内容与链接示例不同。我已经添加了

• self.ReportServiceStatus(win32service.SERVICE_START_PENDING) 和
• self.ReportServiceStatus(win32service.SERVICE_RUNNING) 作为 SvcDoRun 的第一个和最后一个语句
• 'log.error_file': 'c:\\MG\\temp\\CherryPy_Sample_Service.log', 按照 wiki 的指示

重要提示:虽然可以使用控制台 python cherrypy_sample_service.py install 安装服务，但不可能使用 python cherrypy_sample_service.py start 命令启动它。这样做的原因是，以这种方式创建的服务将引用 python 可执行文件，它不是作为服务设计的。

因此，为了进一步测试，我使用以下代码编译了代码:

from cx_Freeze import setup, Executable

exe = Executable(
    script='cherrypy_sample_service.py'
)


build_options = {'includes': ['cherrypy', 'win32serviceutil', 'win32service', 'win32event', 'servicemanager']}

setup(
        name = "CherryPy Sample Service",
        version = "0.1",
        service = ["cherrypy_sample_service.py"],
        options = {"build_exe" : build_options},
        executables = [exe])

在构建过程中，我收到以下警告:

Python27\App\lib\distutils\dist.py:267: UserWarning: Unknown distribution option: 'service'
warnings.warn(msg)

我已根据以下 stack problem answer 添加了此选项.

现在我可以调用 cherrypy_sample_service install、cherrypy_sample_service remove 和 cherrypy_sample_service update。然而，尝试运行该服务(从服务或通过 cherrypy_sample_service start)会导致以下错误:

Error starting service: The service did not respond to the start or control request in a timely fashion.

我卡住了。甚至没有创建日志文件。你能帮我运行这个例子吗？如果我们可以解释并运行示例，我想这对其他为相关问题苦苦挣扎的人也会有用。谢谢!

最佳答案

我刚刚从您提到的 wiki 页面上获取了 3.1 版本，它可以立即运行。 IE。它从命令行安装、启动和停止，就像它从服务管理 GUI 启动和停止一样。

"""
The most basic (working) CherryPy 3.1 Windows service possible.
Requires Mark Hammond's pywin32 package.
"""

import cherrypy
import win32serviceutil
import win32service

class HelloWorld:
    """ Sample request handler class. """

    @cherrypy.expose
    def index(self):
        return "Hello world!"


class MyService(win32serviceutil.ServiceFramework):
    """NT Service."""

    _svc_name_ = "CherryPyService"
    _svc_display_name_ = "CherryPy Service"

    def SvcDoRun(self):
        cherrypy.tree.mount(HelloWorld(), '/')

        # in practice, you will want to specify a value for
        # log.error_file below or in your config file.  If you
        # use a config file, be sure to use an absolute path to
        # it, as you can't be assured what path your service
        # will run in.
        cherrypy.config.update({
            'global':{
                'log.screen': False,
                'engine.autoreload.on': False,
                'engine.SIGHUP': None,
                'engine.SIGTERM': None
                }
            })

        cherrypy.engine.start()
        cherrypy.engine.block()

    def SvcStop(self):
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        cherrypy.engine.exit()

        self.ReportServiceStatus(win32service.SERVICE_STOPPED) 
        # very important for use with py2exe
        # otherwise the Service Controller never knows that it is stopped !

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

测试环境为:XP SP3，Python 2.7.5，CherryPy 3.3,0，pywin32 218.4。

调试技巧

无需构建二进制文件即可运行您的服务。当您从源代码安装 pywin32 服务时，它使用 %PYDIR%\Lib\site-packages\win32\pythonservice.exe 作为服务代理。 IE。所有服务都将其作为运行命令行，使用 REG:\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CherryPyService\PythonClass 定义服务的实际 Python 类。

从命令行运行 pythonservice.exe 并确保它运行时没有错误 (1)。您可能还会注意到，有一个调试选项允许您将服务的标准输出和标准错误附加到终端 (2)。

确保没有防火墙软件阻止 pythonservice.exe 进行网络事件。
