How to pass a value from a synchronous method to asynchronous method within an apex class? - rest

Question

I have made a REST call to a url and need to pass the jsonresponse obtained from the synchronous method to the below asynchronous method.I have used a static variable - strresponse to do the same.But i am getting a null value when i call this value in the asynchronous method.Could this be because asynchronous methods do not remember the value given by a synchronous method? is there any alternate way this could be done?
code below:
public with sharing class myController {
public Static String strResponse ;
#AuraEnabled
public static Map<String, Object> retriveNews(){
HttpRequest httpRequest = new HttpRequest();
httpRequest.setEndpoint('endpoint URL');
httpRequest.setMethod('GET');
try{
Http http = new Http();
HttpResponse httpResponse = http.send(httpRequest);
if(httpResponse.getStatusCode() == 200){
newsController.strResponse = httpResponse.getBody();
} else {
throw new CalloutException(httpResponse.getBody());
}
} catch(Exception ex){
throw ex;
}
Map<String, Object> newsJsonData = new Map<String, Object>();
if(!String.isBlank(newsController.strResponse)){
System.debug('jsonstring:'+newsController.strResponse);
newsJsonData = (Map<String, Object>)JSON.deserializeUntyped(newsController.strResponse);
}
System.debug('jsonstring in retrivenews:'+newsController.strResponse);
if(!newsJsonData.isEmpty()){
return newsJsonData;
} else {
return null;
}
}
#future(callout=true)
public static void insertnews()
{
List<Newsroom__c> nrmlist = new List<Newsroom__c>();
System.debug('jsonstring in insertnews:'+newsController.strResponse);
JSONParser parser = JSON.createParser(newsController.strResponse);
while (parser.nextToken() != null) {
// Start at the array of invoices.
if (parser.getCurrentToken() == JSONToken.START_ARRAY) {
while (parser.nextToken() != null) {
// Advance to the start object marker to
// find next invoice statement object.
if (parser.getCurrentToken() == JSONToken.START_OBJECT) {
objectne nrm = (objectne)parser.readValueAs(objectne.class);
objectne__c nroom = new objectne__c(Author__c = nrm.Author,Description__c = nrm.Description);
String s = JSON.serialize(nrm);
system.debug('Serialized object: ' + s);
nrmlist.add(nroom);
system.debug('list of nrooms:'+ nrmlist);
}
}
}
}
Database.SaveResult[] lsr = Database.insert(nrmlist, false) ;
System.debug(lsr);
}
Error - when newscontroller.insertnews() is called - null string to parser
