即使变量看起来很好，函数也不起作用

Question

函数最终应该这样做并运行以下命令：

Get-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST/Default Web Site'  -filter  'system.web/customErrors'  -name  'mode'

但是，变量像这样搞砸了，添加了当前工作目录并添加了反斜杠：

Get-WebConfigurationProperty : Cannot find path 'C:Usersusername'MACHINEWEBROOTAPPHOSTDefault Web Site''
because it does not exist

ECHO看起来不错，重定向到文件也很好：

Get-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST/Default Web Site'  -filter  'system.web/customErrors'  -name  'mode'

示例运行：

PS C:temp> Get-Check-Func2 "webcA" "mode" "system.web/customErrors"
'MACHINE/WEBROOT/APPHOST/Default Web Site'
system.web/customErrors
mode
Get-WebConfigurationProperty : Cannot find path 'C:Usersusername'MACHINEWEBROOTAPPHOSTDefault Web Site''
because it does not exist.

Get-WebConfigurationProperty -pspath  'MACHINE/WEBROOT/APPHOST/Default Web Site' -filter  'system.web/customErrors'  -name  'mode'

请善待，因为我是PowerShell的新手。

来自科恩/巴什背景。

function Get-Check-Func2 {
$a = Get-Website
$myws = $a.Name
$mypspath = 'MACHINE/WEBROOT/APPHOST/' + "$myws"
$mypspath = '''' + $mypspath + ''''
$myfilter = '''' +  $args[2] + ''''
$myname = '''' +  $args[1] + ''''
 echo "$mypspath"
 echo $args[2]
           Get-WebConfigurationProperty -pspath ` $mypspath ` -filter ` $myfilter ` -name ` $myname
     echo "Get-WebConfigurationProperty -pspath ` $mypspath ` -filter ` $myfilter ` -name ` $myname"
     }

期望Get-WebConfigurationProperty运行，但似乎变量被搞砸了。

您的反引号可能会导致问题。取而代之的是：

Get-WebConfigurationProperty -pspath ` $mypspath ` -filter ` $myfilter ` -name ` $myname

只需这样做：

Get-WebConfigurationProperty -pspath $mypspath -filter $myfilter -name $myname

或者，如果您尝试多行它，请仅在每个参数/输入对之后放置反引号，例如：

Get-WebConfigurationProperty -pspath $mypspath `
                             -filter $myfilter `
                             -name $myname

向

cmdlet 提供大量参数(最终不会以很长的单行结束(的另一个常用选项是使用称为 splatting 的概念。例如：

$GetWebConfigPropertyParams = @{
    PSPath = $mypspath
    Filter = $myfilter
    Name = $myname
}
Get-WebConfigProperty @GetWebConfigPropertyParams

看来你确实有正确的想法马克...我道歉。还从另一位Powershell大师那里得到了一些意见：-(现在工作正常！

function Check-Webca-Select {
param(
$WebsitePSPath  = 'MACHINE/WEBROOT/APPHOST/',
$Filter , 
$ComponentName,
$Myexpect
)
 $a = get-website
 $w = $a.name
  foreach ($WebsiteName in $w) {
   $WebsiteFullPath = "{0}{1}" -f $WebsitePSPath,$WebsiteName
   Get-WebConfigurationProperty -PSPath "$WebsiteFullPath" -Filter $Filter -Name $ComponentName | Select-String "$Myexpect"
 }
}

执行示例

Check-Webca-Select -filter "system.web/customErrors" -ComponentName "mode" -myexpect "Remoteonly">
