复制项：无法将参数绑定到参数“路径”，因为它为空 [英] Copy-Item : Cannot bind argument to parameter 'Path' because it is null

问题描述

我不知道发生了什么。我是Power Shell的新手。
我有一个包含图像的文件夹结构。我正在寻找所有的图像是X天，并将这些图像复制到另外两个位置。我得到的错误是：

 复制项目：无法绑定参数参数'路径'，因为它为空。 
在C：\Documents和Settings \Administrator.VDICORP\Desktop\ProcessOSImages.ps1：37 char：24 
 + copy-item -path<< $ TheImage -destination $ TestSite 
 + CategoryInfo：InvalidData：（:) [Copy-Item]，ParameterBindingValidationException 
 + FullyQualifiedErrorId：ParameterArgumentValidationErrorNullNotAllowed，Microsoft.PowerShell.Commands.CopyItemCommand 
  

我的代码如下：

  $ TodaysDate = get-date 
 $ FileAgeInDays =-2
 $ ImageLocation =\\vdifiles\Print-Room\FileSrv\Barcode-Order
 $ TestSite =\\10.0.100.3\www2.varietydistributors.com\catalog\\\
ewpictures
 $ LiveSite =\\10.0.100.3\Variety Distributors.com\ catalog\\\
ewpictures 
 $ WhenFileWritten = $ TodaysDate.AddDays（$ FileAgeInDays）
 $ IncludeFileTypes =* .jpeg，*。jpg
 $ ExcludeFileTypes =* .psd，*。tif，*。 pdf
 $ LogFile =C：\Temp\FilesCopied.log
 
 $ EmailServer =mx1.domain.com
 $ EmailFrom =alerts @ domain .com
 $ AuthUser =user
 $ AuthPass =pass
 $ XHeaderInfo =X-Header：此电子邮件是从Laservault发送的。 
 $ EmailTo =[e-mail]
 $ EmailSubject =条形码图像摘要。 
 $ EmailBodySent =TEST附加到此电子邮件是一个日志文件，其中将从$ ImageLocation复制到$ TestSite和$ LiveSite的图像以及发送到AS2以发送到订单流。 
 $ EmailBodyNotSent =TEST $ ImageLocation中没有匹配$ WhenFileWritten几天的文件，所以没有发送到$ TestSite，$ LiveSite或AS2。 
 
 $ TheImages = get-childitem $ ImageLocation -include $ IncludeFileTypes -exclude $ ExcludeFileTypes -recurse -force | where-object {$ _。CreationTime -le$ WhenFileWritten - 和$ _。PsIsContainer -ne $ true} 
 
 foreach（$ TheImage中的TheImages）{
 $ FileCount = $ TheImage）.count 
 
 if（！（$ FileCount -eq 0））{
 copy-item -path $ TheImage -destination $ TestSite 
 copy-item -path $ TheImage -destination $ LiveSite 
 
 write-host $ FilesCountimages were copied。 
 write-output $ TheImage>> $ LogFile 
 \\vdifiles\blat $ \blat.exe -attach $ LogFile -to $ EmailTo -s $ EmailSubject -i $ EmailFrom -body $ EmailBodySent -server $ EmailServer -u $ AuthUser -pw $ AuthPass -f $ EmailFrom -x $ XHeaderInfo 
 remove-item $ LogFile 
} else {
 \\vdifiles\blat $ \blat.exe -to $ EmailTo -s $ EmailSubject -i $ EmailFrom -body $ EmailBodyNotSent -server $ EmailServer -u $ AuthUser -pw $ AuthPass -f $ EmailFrom -x $ XHeaderInfo 
} 
} 
  
 
 
 
我会在哪里出错？
解决方案
这是一个简单的问题。你在你的 foreach 语句中翻转你的变量。您有：
  foreach（$ TheImage中的TheImages）{
  
您应该有：
  foreach（$ TheImage in $ TheImages ）{
  
 ---编辑
 
 
 
另一个问题是 Get-ChildItem 不返回任何内容。这是一个小问题，因为 -include 和 -exclude 参数。您正在按如下方式定义变量：
  $ IncludeFileTypes =* .jpeg，*。jpg
 $ ExcludeFileTypes =* .psd，*。tif，*。pdf
  
问题是< c $ c> -include 和 -exclude 参数需要一个字符串数组（ String []  
 
 
如果你创建一个名为的文件，我们可以证明这一点。 jpeg，a.jpg， get-childitem  cmdlt将返回文件。
 
 
 
解决方法是将 $ IncludeFileTypes 和 $ ExcludeFileTypes 变量更改为字符串数组，并返回您期望的结果：
  $ IncludeFileTypes =* .jpeg，*。jpg
 $ ExcludeFileTypes =* .psd，*。tif，*。pdf
  
 
I am not sure what is going on. I am very new to Power Shell.
I have a folder structure containing images in them. I am looking to get all the images that are X days old and copy those images to two other locations. The error I am getting is:
Copy-Item : Cannot bind argument to parameter 'Path' because it is null.
At C:\Documents and Settings\Administrator.VDICORP\Desktop\ProcessOSImages.ps1:37 char:24
+         copy-item -path <<<<  $TheImage -destination $TestSite 
+ CategoryInfo          : InvalidData: (:) [Copy-Item], ParameterBindingValidationException
+ FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.PowerShell.Commands.CopyItemCommand
My code is as follows:
$TodaysDate = get-date
$FileAgeInDays = "-2"
$ImageLocation = "\\vdifiles\Print-Room\FileSrv\Barcode-Order"
$TestSite = "\\10.0.100.3\www2.varietydistributors.com\catalog\newpictures"
$LiveSite = "\\10.0.100.3\Variety Distributors.com\catalog\newpictures"
$WhenFileWritten = $TodaysDate.AddDays($FileAgeInDays)
$IncludeFileTypes = "*.jpeg,*.jpg"
$ExcludeFileTypes = "*.psd,*.tif,*.pdf"
$LogFile = "C:\Temp\FilesCopied.log"

$EmailServer = "mx1.domain.com"
$EmailFrom = "[e-mail]"
$AuthUser = "user"
$AuthPass = "pass"
$XHeaderInfo = "X-Header: This email was sent from Laservault."
$EmailTo = "[e-mail]"
$EmailSubject = "Barcode Images Summary."
$EmailBodySent = "TEST Attached to this email is a log file of what images were copied from $ImageLocation to $TestSite and $LiveSite as well as sent to AS2 to send over to Order Stream."
$EmailBodyNotSent = "TEST There were no files in $ImageLocation that matched $WhenFileWritten days old. So, nothing was sent to $TestSite, $LiveSite or AS2."

$TheImages = get-childitem $ImageLocation -include $IncludeFileTypes -exclude $ExcludeFileTypes -recurse -force | where-object {$_.CreationTime -le "$WhenFileWritten" -and $_.PsIsContainer -ne $true}

foreach ($TheImages in $TheImage) {
$FileCount = ($TheImage).count

if (!($FileCount -eq 0)) {
    copy-item -path $TheImage -destination $TestSite 
    copy-item -path $TheImage -destination $LiveSite 

    write-host $FilesCount "images were copied."
    write-output $TheImage >> $LogFile
    \\vdifiles\blat$\blat.exe -attach $LogFile -to $EmailTo -s $EmailSubject -i $EmailFrom -body $EmailBodySent -server $EmailServer -u $AuthUser -pw $AuthPass -f $EmailFrom -x $XHeaderInfo
    remove-item $LogFile
} else {
    \\vdifiles\blat$\blat.exe -to $EmailTo -s $EmailSubject -i $EmailFrom -body $EmailBodyNotSent -server $EmailServer -u $AuthUser -pw $AuthPass -f $EmailFrom -x $XHeaderInfo                
}
}
Where am I going wrong?
解决方案
It's a simple problem. You flipped your variables in your foreach statement. You have:
foreach ($TheImages in $TheImage) {
You should have:
foreach ($TheImage in $TheImages) {
--- Edit

The other issue is with the Get-ChildItem not returning anything. It's a small problem because of the -include and -exclude parameters you are feeding into it. You are defining the variable like this:
$IncludeFileTypes = "*.jpeg,*.jpg"
$ExcludeFileTypes = "*.psd,*.tif,*.pdf"
The problem is that the -include and -exclude parameters are expecting a string array (String[]) what you are giving them is a straight string.

We can prove this, if you create a file with the name "a.jpeg,a.jpg", the get-childitem cmdlt will return the file.

The solution is to change your $IncludeFileTypes and $ExcludeFileTypes variables to a string array, and it should return the results that you are expecting:
$IncludeFileTypes = "*.jpeg","*.jpg"
$ExcludeFileTypes = "*.psd","*.tif","*.pdf"
