windows - Powershell ConvertTo-SecureString ObjectNotFound

Question

升级到 powershell 3.0 后，现有脚本因错误而停止工作

ConvertTo-SecureString : The term 'ConvertTo-SecureString' is not recognized as the name of a cmdlet, function, script
file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct
and try again.

+ ConvertTo-SecureString
+ ~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (ConvertTo-SecureString:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

我发现 ConvertTo-SecureString 是 supported在 PS 3.0 上。我需要以某种方式包含它吗？

Answer 1

以下不起作用。

C:\contoso>powershell -command {$secured='random text'|ConvertTo-SecureString -AsPlainText -Force;$secured;}

'ConvertTo-SecureString' is not recognized as an internal or external command,
operable program or batch file.

C:\contoso>

以下确实有效。

C:\contoso>copy con: tfile1.ps1
$secured='random text'|ConvertTo-SecureString -AsPlainText -Force;
$secured;
^Z
        1 file(s) copied.

C:\contoso>powershell -file tfile1.ps1
System.Security.SecureString

C:\contoso> 

这也行。

C:\contoso>powershell "& {$secured='random text'|ConvertTo-SecureString -AsPlainText -Force;$secured}"
System.Security.SecureString

C:\contoso>

我会把为什么它不能作为命令工作给其他人，因为我只是一个 powershell 新手。
