Descrizione
The Import-PowerShellDataFile
cmdlet safely imports key-value pairs from hashtables defined in a
.psd1
file. The values could be imported using Invoke-Expression
on the contents of the file.
However, Invoke-Expression
runs any code contained in the file. This could produce unwanted
results or execute unsafe code. Import-PowerShellDataFile
imports the data without invoking the
code. By default there is a 500 key limit, but this can be bypassed with the SkipLimitCheck
switch.
Esempio
Example 1: Retrieve values from PSD1
This example retrieves the key-value pairs stored in the hashtable kept inside the
Configuration.psd1
file. Get-Content
is used to show the contents of the Configuration.psd1
file.
Get-Content .\Configuration.psd1
$config = Import-PowerShellDataFile .\Configuration.psd1
$config.AllNodes
@{
AllNodes = @(
@{
NodeName = 'DSC-01'
}
@{
NodeName = 'DSC-02'
}
)
}
Name Value
---- -----
NodeName DSC-01
NodeName DSC-02
