Question

我有许多Web服务，我试图使用PowerShell在DEV服务器上安装。我想在脚本中包含一个部分，它将所有文件和文件夹从暂存区域复制到DEV服务器上的相应文件夹。

为了做到这一点，我创建了两个并行字符串数组 - 一个包含暂存文件夹的直接文件路径，另一个包含DEV服务器上每个文件夹的名称（我使用其他一些变量来存储目录的其余部分）。

我想创建一个for循环并简单地遍历两个数组，以完成从登台到开发服务器的文件/文件夹传输。但是，当循环运行时，copy-item命令每次都会出现此错误

Copy-Item：找不到接受参数'*'的位置参数。

如果我决定不使用循环，则错误消失并且文件正确传输。只有几天新的PowerShell所以我不确定发生了什么/无法在网上找到任何特定的内容。

变量

#web services
$periscopeWebServices = "periscopeWebServices"
$periscopeRetrieveComments = "periscopeRetrieveComments"
$periscopeRetrieveGeneral = "periscopeRetrieveGeneral"
$periscopeRetrieveMasterSubs = "periscopeRetrieveMasterSubs"
$periscopeRetrieveProducers = "periscopeRetrieveProducers"
$periscopeRetrieveProfiles = "periscopeRetrieveProfiles"
$periscopeRetrieveRelationships = "periscopeRetrieveRelationships"
$periscopeSearch = "periscopeSearch"
$periscopeServicesArray = @($periscopeRetrieveComments, $periscopeRetrieveGeneral, 
                            $periscopeRetrieveMasterSubs, $periscopeRetrieveProducers, 
                            $periscopeRetrieveProfiles, $periscopeRetrieveRelationships, 
                            $periscopeSearch)


#staging areas
$stagingComments = "\\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveComments"
$stagingGeneral = "\\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveGeneral"
$stagingMasterSubs = "\\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveMasterSubs"
$stagingProducers = "\\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveProducers"
$stagingProfiles = "\\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveProfiles"
$stagingRelationships = "\\install\PeriscopeServices\periscopeWebServices\periscopeRetrieveRelationships"
$stagingSearch = "\\install\PeriscopeServices\periscopeWebServices\periscopeSearch"
$stagingArray = @($stagingComments, $stagingGeneral, $stagingMasterSubs, $stagingProducers
                  $stagingProfiles, $stagingRelationships, $stagingSearch)

#server variables
$domain = "InsideServices.dev.com"
$directory = "E:\webcontent"
$domainpath = "$directory\$domain"

循环 - 在'copy-item'上抛出错误

#copy files
Write-Host "Copying Files" -ForegroundColor Yellow
For ($i=0; $i -lt $periscopeServicesArray.Length; $i++)
{
    Write-Host "Copying $($periscopeServicesArray[$i])" -ForegroundColor Yellow
    if(Test-Path -path "$domainpath\$periscopeWebServices\$($periscopeServicesArray[$i])")
    {
        copy-item -Path $($stagingArray[$i])\* -Destination $domainpath\$periscopeWebServices\$($periscopeServicesArray[$i]) -recurse -Force
    }
}

成功的复制项目命令

copy-item -Path $stagingComments\* -Destination $domainpath\$periscopeWebServices\$periscopeRetrieveComments -recurse -Force

我认为这是因为您在循环中使用了子表达式$()，但不在外部。试试这些：

"$($stagingArray[$i])\*"

在引号中包围它使得它将整个事物评估为字符串。

$($stagingArray[$i]) + '\*'

这将连接子表达式的结果和包含\*的字符串。

找不到接受参数'\ *'的位置参数
