python 计划任务

Python check for Completed and failed Task Windows scheduler

有谁知道我可以查看的方式或资源来检查任务计划程序中所有Windows任务的状态？我想看看是否看到任务失败或成功。我想在Python中做到这一点。

我已经看过一些使用win32com.client模块的信息。我可以看到什么任务，但是找不到完成的工作的状态。

import win32com.client
scheduler = win32com.client.Dispatch("Schedule.Service")
scheduler.Connect()
tasks = scheduler.GetRunningTasks(1)
names = [tasks.Item(i+1).Name for i in range(tasks.Count)]
print names

以下内容使用Task Scheduler API来打印所有已注册任务的基本信息，包括最近的运行时间和结果。

import win32com.client

TASK_ENUM_HIDDEN = 1
TASK_STATE = {0: 'Unknown',
  1: 'Disabled',
  2: 'Queued',
  3: 'Ready',
  4: 'Running'}

scheduler = win32com.client.Dispatch('Schedule.Service')
scheduler.Connect()

n = 0
folders = [scheduler.GetFolder('\')]
while folders:
folder = folders.pop(0)
folders += list(folder.GetFolders(0))
tasks = list(folder.GetTasks(TASK_ENUM_HIDDEN))
n += len(tasks)
for task in tasks:
settings = task.Definition.Settings
print('Path : %s' % task.Path)
print('Hidden : %s' % settings.Hidden)
print('State : %s' % TASK_STATE[task.State])
print('Last Run : %s' % task.LastRunTime)
print('Last Result: %s
' % task.LastTaskResult)
print('Listed %d tasks.' % n)

这仅从列表中的根文件夹开始。每次循环都会弹出一个文件夹。推送其所有子文件夹；并列出文件夹中的任务。一直持续到文件夹列表为空。

COM接口

ITaskService
ITaskFolder
IRegisteredTask
ITaskDefinition
ITaskSettings

另外，这是一个walk_tasks生成器，它基于标准库的os.walk建模。

可以使用schtasks和at从命令行访问任务计划程序

schtasks：https://technet.microsoft.com/zh-CN/library/cc772785%28v=ws.10%29.aspx

网址：https://technet.microsoft.com/zh-cn/library/cc755618%28v=ws.10%29.aspx

使用subprocess.check_output从python运行schtasks /query
使用python运行Windows Shell命令

tasklist命令列出所有正在运行的程序和服务，或者在Powershell get-process中列出
