How to extract the string from a NoteProperty returned within a PSCustomObject..


I am struggling to extract the string from a NoteProperty returned within a PSCustomObject.

I am looking to query a API from Cisco (Cisco PSIRT openVuln). I have managed to authenticate using the following code:

$client_id = “client_id-removed”
$client_secret = “client_secret_removed”

$tokenParams = @{

$token = (Invoke-WebRequest -contenttype “application/x-www-form-urlencoded” -Uri “” -Method POST -Body $tokenParams)

$token.AllElements | get-member

Which (obviously with the correct client_id & client_secret values) returns the API session token in a NoteProperty as a string, like this:

TypeName: System.Management.Automation.PSCustomObject

Name MemberType Definition

Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
innerHTML NoteProperty string innerHTML=…
innerText NoteProperty string innerText={“access_token”:“Vo5MtBD7AvgcdwF3U5hwj83wskiw”,“token_type”:“Bearer”,“expires_in”:3599}
outerHTML NoteProperty string outerHTML=…
outerText NoteProperty string outerText={“access_token”:“Vo5MtBD7AvgcdwF3U5hwj83wskiw”,“token_type”:“Bearer”,“expires_in”:3599}
tagName NoteProperty string tagName=HTML

I am stuck on how to extract InnerText as variables (access_token, token_type, etc)

I would appreciate any help you can offer.

Many Thanks

Hi Martin,

I believe you should be able to assign the contents of InnerText as such

 $Varname = $token.AllElements.innerText 

After that point you should be able to split the contents by “,”.

Hope that helps.

Thank you Brendan… I am so dumb!
