How to get elements values from Http response

Hi All,

 

string templateId = '00XN0000002LbV8MAK';
string domainUrl = URL.getSalesforceBaseUrl().toExternalForm();
HttpRequest req = new HttpRequest();
req.setHeader('Authorization', 'Bearer ' + UserInfo.getSessionID());
req.setHeader('Content-Type', 'application/json');
req.setEndpoint(domainUrl+'/services/data/v51.0/tooling/query/?q=select+id,SenderType,templateId+from+WorkflowAlert+where+templateId=\''+templateId+'\'');
req.setMethod('GET'); 
Http h = new Http();
HttpResponse res = h.send(req);
system.debug(res.getBody());
Map<String, Object> deserialized = (Map<String, Object>)JSON.deserializeUntyped(res.getBody());
Object data1 = deserialized.get('records');
System.debug(deserialized.get('records'));
System.debug(deserialized.get('size'));

 

res.getBody(); -> {"size":1,"totalSize":1,"done":true,"queryLocator":null,"entityTypeName":"WorkflowAlert","records":[{"attributes":{"type":"WorkflowAlert","url":"/services/data/v51.0/tooling/sobjects/WorkflowAlert/01WN00000005esGMAQ"},"Id":"01WN00000005esGMAQ","SenderType":"CurrentUser","TemplateId":"00XN0000002LbV8MAK"}]}

 

Im trying to get ,"SenderType":"CurrentUser"  value but values is not returning: 

System.debug(deserialized.get('records')); --> [{"TemplateId":"00XN0000002LbV8MAK","SenderType":"CurrentUser","Id":"01WN00000005esGMAQ","attributes":{"url":"/services/data/v51.0/tooling/sobjects/WorkflowAlert/01WN00000005esGMAQ","type":"WorkflowAlert"}}]

Hi Rakesh

Please use the below code 
Map<String, Object> deserialized = (Map<String, Object>)JSON.deserializeUntyped(res.getBody());
List<Object> m2 = (List<Object>) deserialized.get('records');
Map<String, Object> m3 = (Map<String, Object>) m2[0];
system.debug(m3.get('SenderType'));

Hi,

You can take references from the below code.

Map<String, Object> m = (Map<String, Object>) JSON.deserializeUntyped(res.getBody());
Map<String, Object> m2 = (Map<String, Object>) m.get('records');
 System.debug('SenderType:::'+m2.get('SenderType'));
for(String s:m2.keyset()) {
     System.debug(m2.get(s));
}

Please let me know it is working or not?

Please mark it as the Best Answer so that other people would take references from it.

Hi Tirupathi, 

Thank you!

I tried your approach but it is thowing an error.

Line: 12, Column: 1
System.TypeException: Invalid conversion from runtime type List<ANY> to Map<String,ANY>

 

Map<String, Object> m = (Map<String, Object>) JSON.deserializeUntyped(res.getBody());
Map<String, Object> m2 = (Map<String, Object>) m.get('records'); // error
 System.debug('SenderType:::'+m2.get('SenderType'));
for(String s:m2.keyset()) {
     System.debug(m2.get(s));
}

Thank You Abdul, It made simple, before i was using this code to get values.

 

while (parser.nextToken() != null) {
                if ((parser.getCurrentToken() == JSONToken.FIELD_NAME)){
                    String fieldName = parser.getText();
                    parser.nextToken();
                    String fieldValue=parser.getText();
                    
                    if(fieldName == 'Sendertype') {
                        workflowEmailAlertSendertype.add(fieldValue);
                        system.debug('f value :'+fieldvalue);
                        sendertype = fieldValue;
                    }
                }
            }
