How to get a value from powershell where the key has a dot at the beginning?-CodePudding

How do I get the value of a json where the key has "." at the beginning?

$json = '{".expires":"2022-10-13"}' | ConvertFrom-Json

cls
$json..expires #trying to get the value 2022-10-13

Error:

On the line:4 caractere:8
  $json..expires
         ~
You must provide a value expression after the '..' operator.
On the line:4 caractere:8
  $json..expires
         ~~~~~~~
Token 'expires' unexpected in the expression or statement.
      CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
      FullyQualifiedErrorId : ExpectedValueExpression

The code above gives error if I put a colon, is there another way?

CodePudding user response：

You can enclose the property name in quotes.

$json.".expires"
