在 Powershell 中将字符串转换为哈希表

Question

我的要求有点特殊，但很容易理解。

我得到一个字符串，我想将其用作哈希表，但我做不到，我的格式非常特殊，我还没有成功使用 ConvertFrom-StringData 等方法。

格式预览：

@{id = 04cc943e-14a8-4bf6-8601-bd6fde3cc229; name = 7.10 10-16 - 6.0 * * * * | 1 0 0 0; privileges =}

因此，我希望能够访问 name 属性的内容。我在那里花了很多时间但没有成功...... 感谢您的帮助

Answer 1

因此您可以进行字符串解析并结合使用拆分和修剪。

$text = "@{id = 04cc943e-14a8-4bf6-8601-bd6fde3cc229; name = 7.10 10-16 - 6.0 * * * * | 1 0 0 0; privileges =}"

#this is to get rid of @{}
$preparedText = $text.Substring(2,$text.Length-3)
$obj = @{}

foreach ($kv in $preparedText.Split(";")) { 
    #Get key from string (which is "key = value")
    $key = $kv.Trim().Split("=")[0].Trim()
    Write-Host "Key = $key"
    #Get value from string
    $value = $kv.Trim().Split("=")[1].Trim()
    Write-Host "Value = $value"

    #Assign key-object pair to hashtable
    $obj[$key] = $value
}

Write-Host "obj.name = $($obj.name);`nobj.id = $($obj.id);`nobj.privileges = $($obj.privileges)"

哪个returns:

obj.name = 7.10 10-16 - 6.0 * * * * | 1 0 0 0;
obj.id = 04cc943e-14a8-4bf6-8601-bd6fde3cc229;
obj.privileges =

另一种方法是使用 convertfrom-stringdata cmdlet，记录在此处： Link to official MS documentation

The ConvertFrom-StringData cmdlet converts a string that contains one or more key and value pairs into a hash table. Because each key-value pair must be on a separate line, here-strings are often used as the input format. By default, the key must be separated from the value by an equals sign (=) character.

使用@Karolina Ochlik 中的 OP 示例 post:

$text = "@{id = 04cc943e-14a8-4bf6-8601-bd6fde3cc229; name = 7.10 10-16 - 6.0 * * * * | 1 0 0 0; privileges =}"
#this is to get rid of @{}
$preparedText = $text.Substring(2,$text.Length-3)
# replace semicolon with newline - `n needs double quotes
$preparedText.replace(';',"`n") | ConvertFrom-StringData

这将创建输出：

Name                           Value
----                           -----
name                           7.10 10-16 - 6.0 * * * * | 1 0 0 0
id                             04cc943e-14a8-4bf6-8601-bd6fde3cc229
privileges

真正的工作在一行中完成

$preparedText.replace(';',"`n") | ConvertFrom-StringData

我希望这对某人有所帮助。
