Question

我具有以下功能，该功能可隐藏密码中间字符，并使第一个字符和最后一个字符可见

function Hide-ConnectionStringPassword {
    param(
       [parameter(Mandatory,ValueFromPipeline)]
       [System.Data.SqlClient.SqlConnectionStringBuilder]$ConnectionString
    )
    [string]$FistChar = $ConnectionString.Password[0]
    [string]$LastChar = $ConnectionString.Password[($ConnectionString.Password.Length - 1)]
    [string]$Stars = '*' * ($ConnectionString.Password.Length - 2)
    $ConnectionString.Password = $FistChar + $Stars + $LastChar 
    return $ConnectionString.ConnectionString
}

用法：

Hide-ConnectionStringPassword 'Connection Timeout=120;User Id=UID1;Data Source=datasource.com;Password=password12!553;'

输出：

Data Source = datasource.com;用户 ID = UID1;密码= p ************ 3;连接超时= 120

我还有其他采用JSON格式的连接字符串，因此强制转换为sqlbuilder不适用于这种类型的输入

{“身份验证类型“：” UsernamePassword“，”用户名“：” someID1“，”密码“：” Yu＃gh456！ts“，” EncryptConnection“：true}

我能做的一件事就是这样：

$Json = '{"Authentication Kind":"UsernamePassword","Username":"someID1","Password":"Yu#gh456!ts","EncryptConnection":true}'
$Sql = $Json | ConvertFrom-Json
$Sql.Password

使用

$Sql.gettype().name

我得到

PSCustomObject

我想在函数中应用它，以便检查字符串输入是否为pscustomobject类型，以便不将其强制转换为sqlbuilder

伪代码 ：

function Hide-ConnectionStringPassword {
    if ($input.gettype().name -ne 'PSCustomObject')
    {
    param(
       [parameter(Mandatory,ValueFromPipeline)]
       [System.Data.SqlClient.SqlConnectionStringBuilder]$ConnectionString
    )}
    else
    {
    param(
       [parameter(Mandatory,ValueFromPipeline)]
       $ConnectionString
    )}
    [string]$FistChar = $ConnectionString.Password[0]
    [string]$LastChar = $ConnectionString.Password[($ConnectionString.Password.Length - 1)]
    [string]$Stars = '*' * ($ConnectionString.Password.Length - 2)
    $ConnectionString.Password = $FistChar + $Stars + $LastChar 
    return $ConnectionString.ConnectionString
}

您只需删除该参数中的强制输入即可。然后将if-else逻辑移到脚本Process {}或Begin {}脚本块中。

function Hide-ConnectionStringPassword {

    param(
       [parameter(Mandatory,ValueFromPipeline)]
       $ConnectionString
    )

    if ($ConnectionString.GetType().Name -ne "PSCustomObject") {
    $ConnectionString = $ConnectionString -as [System.Data.SqlClient.SqlConnectionStringBuilder]
    }

    [string]$FistChar = $ConnectionString.Password[0]
    [string]$LastChar = $ConnectionString.Password[($ConnectionString.Password.Length - 1)]
    [string]$Stars = '*' * ($ConnectionString.Password.Length - 2)
    $ConnectionString.Password = $FistChar + $Stars + $LastChar 
    return $ConnectionString.ConnectionString
}

如何在函数中创建条件参数？
