How to store 1 output from one script to another? - powershell

Question

Suppose I have script1.ps1 with the following code:
Function Renew_Token($token) {
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("X-Vault-Token", $token)
$response = Invoke-RestMethod -method POST -uri "https://vault.com:8243/v1/auth/token/renew-self" -ContentType 'application/json' -headers $headers
$response| ConvertTo-Json -depth 100
}
Function getValues($token) {
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("X-Vault-Token", $token)
$response = Invoke-RestMethod -method GET -uri "https://vault.com:8243/v1/secret/vault/development" -ContentType 'application/json' -headers $headers
$response.data| ConvertTo-Json -depth 100
}
Renew_Token $token
write-host "token renewed!"
write-host "Vault Values:"
getValues $token
This gives me back a response like this:
{
"request_id": "ghgdf5-yuhgt886-gfd76trfd",
"lease_id": "",
"renewable": false,
"lease_duration": 0,
"data": null,
"wrap_info": null,
"warnings": null,
"auth": {
"client_token": "i657ih4rbg68934576y",
"accessor": "t543qyt54y64y654y",
"policies": [
"default",
"vault"
],
"token_policies": [
"default",
"vault"
],
"metadata": null,
"lease_duration": 2000,
"renewable": true,
"entity_id": ""
}
}
token renewed!
Vault Values:
{
"abc": "1234",
"def": "897",
"klm": "something12"
}
Now consider in a Script2.ps1, I call script1
$second_response = & ".\Script1.ps1"
of course, $second_response will store the 2 responses above as output.
How can i store JUST the second response as keys/values say in a table in Script2? i.e. this part:
{
"abc": "1234",
"def": "897",
"klm": "something12"
}
$HashTable = #{ }
$HashTable.Add($second_response.key, $second_response.value)
in other words, somehow the $second_response variable should only store this output:
{
"abc": "1234",
"def": "897",
"klm": "something12"
}
Note: that second response is considerably dynamic. meaning there could be different values on different environments. therefore, i want to be able to DYNAMICALLY store whatever is in this response, not hardcode the values
Also, I need the 2 responses in script 1 because i use script1 for other purposes, such as say i want to only view the vault content. script2 will have operations on the response from script1, so i have them separated for this convenience and flexibility
UPDATE: Following #kuzimoto suggestion, i removed the output and converting the response back from JSON, i get this output from Script2:
abc: 1234
def: 897
klm: something12

I can't comment yet, but here's a couple possibilities:
Edit script1.ps1
You don't mention if you need the first set of results. If you don't, just simply delete or comment out this line $response| ConvertTo-Json -depth 100 from the Renew_Token function.
Parse the output of script1.ps1 as json
You're passing the output of script1 to script2 as plain text. Simply change $second_response = & ".\Script1.ps1" to $second_response = & ".\Script1.ps1" | ConvertFrom-Json. Then when you want to access the second response, use $second_response[1] as both sets of JSON get added to a custom PS Object and can be accessed individually like you would an array.
