WebserviceCall b = new WebserviceCall(controller_inv);
b.getaccesstoken();
system.debug( b.getaccesstoken());
}
}
Might be you response returned as null. I just added few condition in your code. Can you try your schedule with the below code,
public with sharing class WebserviceCall { public WebserviceCall(ApexPages.StandardController controller) { } public String message {get; set;} public PageReference getaccesstoken() { string jsonstring ='userName=test@gmail.com&Password=123&grant_type=password'; HttpRequest req = new HttpRequest(); HttpResponse res = new HttpResponse(); Http http = new Http(); // req.setClientCertificateName('Client Certificate'); req.setEndpoint('http://google.com'); req.setMethod('POST'); // req.setHeader('SOAPAction', 'Soap Action'); //req.setHeader('Authorization','Auth Token'); req.setBody(jsonstring); try { res = http.send(req); message = res.getBody(); TokenInformation token = new TokenInformation(); token =(TokenInformation)System.JSON.deserialize(message, TokenInformation.class); // JSONParser parser = JSON.createParser(res.getBody()); if(token != null) { System.debug(token.access_token); //HttpServletResponse httpResponse = (HttpServletResponse)response; string s = token.access_token; string a1 = s.length() >=255 ? s.substring(0,255) : null; string a2 = s.length() >= 510 ? s.substring(255,510) : null; string a3 = s.length() >=510 ? s.substring (510,s.length()) : null; //Here SessionData__c is custom setting used for store access_token SessionData__c objToken = new SessionData__c(); objToken.Name ='token2'; objToken.Id ='a0G28000000ENAI'; objToken.Access_Token1__c =a1;objToken.Access_Token2__c =a2; objToken.Access_Token3__c =a3; upsert objToken; } } } catch(System.CalloutException e) { System.debug('Callout error: '+ e); message = res.toString() + res.getBody(); System.debug(res.toString()); } return null; } }Is your webservice call working in vf? or totally your class not working?
