我正在研究一些使用Power
shell更新执行各种应用程序的现有计划任务的发布自动化脚本.在我的脚本中,我可以设置应用程序的路径和工作目录,但似乎不会将更改保存回任务.
function CreateOrUpdateTaskRunner {
param (
[Parameter(Mandatory = $TRUE,Position = 1)][string]$PackageName,[Parameter(Mandatory = $TRUE,Position = 2)][Version]$Version,Position = 3)][string]$ReleaseDirectory
)
$taskScheduler = New-Object -ComObject Schedule.Service
$taskScheduler.Connect("localhost")
$taskFolder = $taskScheduler.GetFolder('\')
foreach ($task in $taskFolder.GetTasks(0)) {
# Check each action to see if it references the current package
foreach ($action in $task.Definition.Actions) {
# Ignore actions that do not execute code (e.g. send email,show message)
if ($action.Type -ne 0) {
continue
}
# Ignore actions that do not execute the specified task runner
if ($action.WorkingDirectory -NotMatch $application) {
continue
}
# Find the executable
$path = Join-Path $ReleaseDirectory -ChildPath $application | Join-Path -ChildPath $Version
$exe = Get-ChildItem $path -Filter "*.exe" | Select -First 1
# Update the action with the new working directory and executable
$action.WorkingDirectory = $exe.DirectoryName
$action.Path = $exe.FullName
}
}
}
到目前为止,我还没有在文档中找到明显的保存功能(https://msdn.microsoft.com/en-us/library/windows/desktop/aa383607(v=vs.85).aspx).我在这里采取了错误的方法,需要搞乱任务XML吗？
RegisterTask方法具有您将使用的更新标志.像这样的东西：
# Update the action with the new working directory and executable $action.WorkingDirectory = $exe.DirectoryName $action.Path = $exe.FullName #Update Task $taskFolder.RegisterTask($task.Name,$task.Definition,4,"<username>","<password>",1,$null)
有关每个参数的详细信息,请参阅msdn文章.
