Question

我正在尝试使用Powershell创建文件监视器。一旦文件被更改，就需要它运行我的PHP脚本。我的第一个想法是，一切都很完美，但似乎只是触发了一次。

一旦我更改了给定文件夹中的* .js文件，PHP脚本就会触发。但它只触发一次。几分钟后我再次更改了文件，但php脚本不再执行（即使Write-Host没有任何内容）。

这是我的Powershell-Script：

#By BigTeddy 05 September 2011 

#This script uses the .NET FileSystemWatcher class to monitor file events in folder(s). 
#The advantage of this method over using WMI eventing is that this can monitor sub-folders. 
#The -Action parameter can contain any valid Powershell commands.  I have just included two for example. 
#The script can be set to a wildcard filter, and IncludeSubdirectories can be changed to $true. 
#You need not subscribe to all three types of event.  All three are shown for example. 
# Version 1.1 

$global:folder = 'C:\Users\Dario\Desktop\scripts' # Enter the root path you want to monitor. 
$filter = '*.js'  # You can enter a wildcard filter here. 

# In the following line, you can change 'IncludeSubdirectories to $true if required.                           
$fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property @{IncludeSubdirectories = $false;NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'} 

# Here, all three events are registerd.  You need only subscribe to events that you need: 

Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action { 
$name = $Event.SourceEventArgs.Name 
$changeType = $Event.SourceEventArgs.ChangeType 
$timeStamp = $Event.TimeGenerated 
Write-Host "The file '$name' was $changeType at $timeStamp" -fore green 
} 

Register-ObjectEvent $fsw Changed -SourceIdentifier FileChanged -Action { 
$name = $Event.SourceEventArgs.Name 
$changeType = $Event.SourceEventArgs.ChangeType 
$timeStamp = $Event.TimeGenerated 
$path = $global:folder + "\" + $name

    Try {
        Write-Host "The file '$name' was $changeType at $timeStamp" -fore white 
        cmd.exe /k ""C:\Users\Dario\Desktop\mep\script.bat" "$path""
    } Catch {
        Write-Host "Problems"
    }
} 

# To stop the monitoring, run the following commands: 
# Unregister-Event FileDeleted 
# Unregister-Event FileCreated 
# Unregister-Event FileChanged

有趣的问题！我开始谷歌搜索并找到了this现成功能：

它似乎正是你想做的......

Answer 2

我不想粗鲁，但我有另一种解决方案。我在IntelliJ上开发。 IntelliJ有一个自己的File Watcher，这就是我使用这个的原因。

带有Powershell的File Watcher不会始终触发
