Question

我有一个有效的PowerShell脚本。出于维护原因，我想创建另一个脚本，我将从第一个脚本中调用我将调用的所有参数。

如何创建和调用参数文件？

这是我的剧本：

param([string] $dataSource = "server")

$Stamp = (Get-Date).toString("yyyy/MM/dd HH:mm:ss")
$Stamp1 = (Get-Date).toString("yyyy-MM-dd")
$Logfile = "E:\PowerShell\Log\file$stamp1.log"

$file = "file$stamp1.csv"
$extractFile = @"
E:\PowerShell\Output\$file 
"@

[string]$sqlCommand1 =get-content -path E:\PowerShell\SQL\sql.sql
[string]$sqlCommand =$sqlCommand1

$authentication =  ("User Id= user ;Password=pswd;" -f $plainCred.Username, $plainCred.Password)

Add-Type -assemblyname system.data

$factory = [System.Data.Common.DbProviderFactories]::GetFactory  ("Teradata.Client.Provider")

$connection = $factory.CreateConnection() 

$connection.ConnectionString = "Data Source = $dataSource;Connection Pooling Timeout=300;$authentication"  

$connection.Open()

if ($connection.State -eq 'Open') {$logstring ="Connexion réussite"} else { $logstring ="echec Connexion" }

$command = $connection.CreateCommand()
$command.CommandText = $sqlCommand

$adapter = $factory.CreateDataAdapter()
$adapter.SelectCommand = $command

$dataset = new-object System.Data.DataSet


try
{
[void] $adapter.Fill($dataset)

$dataset.Tables | Select-Object -Expand Rows

}
finally
{
$connection.Close()
}

if (!$dataset) {$logstring1 ="extraction vide"} else {$logstring1     ="extraction réussite"}

($DataSet.Tables[0] | ConvertTo-Csv  -delimiter ";" -NoTypeInformation )   -replace '"', "" | Out-File $extractFile -Force 

$datafileExists = Test-Path $extractFile

if ($datafileExists)
    {
        $logstring2 ="Fichier data créé"
    } 
else 
    {
       $logstring2 ="Fichier data non créé"
    }

Add-content $Logfile -value ($Stamp+':'+$logstring) 
Add-content $Logfile -value ($Stamp+':'+$logstring1) 
Add-content $Logfile -value ($Stamp+':'+$logstring2)

我创建了一个参数文件

$Stamp1 = (Get-Date).toString("yyyy-MM-dd")
$Logfile = "E:\PowerShell\Log\file$stamp1.log"
$file = "file$stamp1.csv"
$extractFile = @"
E:\PowerShell\Output\$file 
"@
$authentication =  ("User Id= user ;Password=paswd;" -f      $plainCred.Username, $plainCred.Password)
$Stamp = (Get-Date).toString("yyyy/MM/dd HH:mm:ss")

我从我的第一个脚本中调用它：

$ScriptPath = Split-Path $MyInvocation.InvocationName
& "$ScriptPath\param.ps1"

但我的变量无法识别，我有这些错误：

如果您使用＆＃39;＆amp;＆＃39;执行ps1并且在该范围内可以创建创建的变量。你可以像这样改变范围：

df.loc[df['\tyear'] == 2000, 'rainfall (mm)'].sum()

更好的解决方案是使用＆＃39;。＆＃39;而不是＆＃39;＆＃39;所以你从ps1获得的代码包含在另一个ps1中。

所以范围是相同的，因为它在同一个脚本中。

使用PowerShell创建参数脚本以由另一个脚本
