PowerShell将字符串转换为json

Question

在PowerShell中,我有以下字符串,我从文件中读取,需要转换为json:

"@{Account='User01';Domain='Domain01';Admin='True'}"

在我的PS脚本中,我尝试这样做(简化):

$myStr = "@{Account='User01';Domain='Domain01';Admin='True'}" | ConvertTo-Json
$mystr

结果myStr是:

"@{Account=\u0027User01\u0027;Domain=\u0027Domain01\u0027;Admin=\u0027True\u0027}"

而不是我可以使用的json.请注意,@字符串开头的符号是我从文件中获得的符号.

如何将其转换为我可以使用的对象？

您可以尝试一些字符串操作以获得预期的JSON格式,然后使用ConvertFrom-Json它将其转换为PSCustomObject.

简单示例:(简单,因为这假设被替换的这些字符只是分隔符)

# First, clean up the string.
PS C:\> $mystring = "@{Account='User01';Domain='Domain01';Admin='True'}"
PS C:\> $mystring = $mystring -replace "^@", ""
PS C:\> $mystring = $mystring -replace "=", ":"
PS C:\> $mystring = $mystring -replace ";", ","
PS C:\> $mystring
{Account:'User01',Domain:'Domain01',Admin:'True'}

# Afterwards, convert to PSCustomObject.
PS C:\> $myobject = $mystring | ConvertFrom-Json
PS C:\> $myobject

Account                                 Domain                                  Admin
-------                                 ------                                  -----
User01                                  Domain01                                True

这也可以转换回JSON:

PS C:\> $myobject | ConvertTo-Json
{
    "Account":  "User01",
    "Domain":  "Domain01",
    "Admin":  "True"
}
