Analisi dell'oggetto JSON in Salesforce Apex

Come analizzare un jsonObject che si trova in un formato specificato in Apex?Analisi dell'oggetto JSON in Salesforce Apex

Ho bisogno della Lista < String> dall'array items che contiene l'attributo id. Qual è un metodo appropriato?

Per analizzarlo, cerco di creare una classe con il codice:

public class JSON2Apex { 

    public class Items { 
     public String kind; 
     public String etag; 
     public String id; 
     public String status; 
     public String htmlLink; 
     public String created; 
     public String updated; 
     public String summary; 
     public String description; 
     public String location; 
     public Creator creator; 
     public Creator organizer; 
     public Start start; 
     public Start end; 
     public String iCalUID; 
     public Integer sequence; 
     public Reminders reminders; 
    } 

    public class Reminders { 
     public Boolean useDefault; 
    } 

    public class Start { 
     public String dateTime; 
    } 

    public class Creator { 
     public String email; 
     public String displayName; 
     public Boolean self; 
    } 

    public String kind; 
    public String etag; 
    public String summary; 
    public String updated; 
    public String timeZone; 
    public String accessRole; 
    public List<DefaultReminders> defaultReminders; 
    public List<Items> items; 

    public class DefaultReminders { 
     public String method; 
     public Integer minutes; 
    } 

}

Ma in questa classe si sta dimostrando una certa parola chiave riservata è facile come fine, dateTime ecc in modo non può procedere oltre con questo approccio .

È possibile utilizzare la funzione deserializeUntyped di lavorare con il JSON negli oggetti oggetto/list/mappa piana. Devi solo ricordarti di trasmettere tutto al tipo atteso (esattamente come faresti in Java). Quindi, per accedere al campo id di ogni elemento, faresti

public void parse() { 
    Map<String, Object> root = (Map<String, Object>)JSON.deserializeUntyped(getJsonToParse()); 
    List<Object> items = (List<Object>)root.get('items'); 
    for (Object item : items) { 
     Map<String, Object> i = (Map<String, Object>)item; 
     System.debug(i.get('id')); 
    } 
}

che genera questo output di debug:
