自动检测&后台复制光盘内容

原理：利用python的win32模块，注册服务，让代码在后台运行，检测光盘并拷贝文件

启动的方法就是直接在cmd下，main.py install ，然后去windows 的服务下就可以看到The smallestpossible Python Service 这个服务，你可以启动，停止，还可以设置成开机自动启动。启动服务后，会自动检测光盘并在后台拷贝文件

main.py

import win32serviceutil
import win32service
import win32event
import CopyDvd2Hard

class SmallestPythonService(win32serviceutil.ServiceFramework):
    _svc_name_ = "SmallestPythonService"
    _svc_display_name_ = "The smallest possible Python Service"
    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self, args)
        # Create an event which we will use to wait on.
        # The "service stop" request will set this event.
        self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)

    def SvcStop(self):
        # Before we do anything, tell the SCM we are starting the stop process.
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        # And set my event.
        win32event.SetEvent(self.hWaitStop)

    def SvcDoRun(self):
        #实际运行代码#
        CopyDvd2Hard.copydvd2hard()
        win32event.WaitForSingleObject(self.hWaitStop, win32event.INFINITE)

if __name__==‘__main__‘:
    win32serviceutil.HandleCommandLine(SmallestPythonService)

CopyDvd2Hard.py

__author__ = ‘M‘
import os
import win32file

def copydvd2hard(dstdir=‘temp‘):
    #检测本地的最后一个光驱和硬盘分区
    letters = [l.upper() + ‘:‘ for l in ‘abcdefghijklmnopqrstuvwxyz‘]
    cdrom = ‘‘
    harddrive = ‘‘
    for drive in letters:
        if win32file.GetDriveType(drive) == 3:
            harddrive = drive
        if win32file.GetDriveType(drive) == 5:
            cdrom = drive
    cdrom += ‘/‘
    harddrive = harddrive + ‘/‘ + dstdir
    #检测光驱内是否有光盘，等待光盘插入
    while os.system(‘cd /d‘ + cdrom):
        time.sleep(5)
    #拷贝文件
    shutil.copytree(cdrom, harddrive)
