How to parse a json array response in script Runner

[serge calderara]

Dear all,

From script runner script we are using MS Graph APi to get information from particular user mentionned in an issue.

For that we call an API endpoint using HttpBuilder and from the response json we get the follwing output :

{
 @odata.context=https://graph.microsoft.com/v1.0/$metadata#users, 
 value=[{         businessPhones=[], 
         displayName=Serge Cal GMAIL, 
         givenName=null, 
         jobTitle=null, 
         mail=user1.tom@gmail.com, 
         mobilePhone=null, 
         officeLocation=null, 
         preferredLanguage=null, 
         surname=null,         userPrincipalName=user1.tom_gmail.com#EXT#@SCALDERARA.onmicrosoft.com,          id=253bca1d-6c03-441f-92e4-e206c7d180f7
       }]
}

The method sample I use is as below :

def http = new HTTPBuilder('https://graph.microsoft.com/v1.0/users?')
http.request(GET) {

requestContentType = ContentType.JSON
uri.query = [ $filter:"mail eq '$userEmail'".toString() ]

headers.'Authorization' = "Bearer " + AuthToken

response.success = { resp, json ->
_userId=json["value"]["id"]  <<<= Do not work !!!!!

}

How can I access the value of value[0].Id member from the response delegate ?

Thanks for help
