Ler subitem de um JSON

23/01/2020

Ol�. Preciso fazer a leitura dos subitens de um JSON. Os items consigo buscar perfeitamento conforme o c�digo abaixo. O que n�o consegui foi a partir de cada item, buscar as informa��es dos "subItems". Algu�m pode me ajudar?

var
  jsonObj, jSubObj: TJSONObject;
  ja: TJSONArray;
  jv: TJSONValue;
  i: Integer;
begin
  jsonObj := TJSONObject.ParseJSONValue(TEncoding.ASCII.GetBytes(Memo1.Text), 0) as TJSONObject;

  jv := jsonObj.Get(''items'').JsonValue;
  ja := jv as TJSONArray;

  Memo2.Clear;

  for i := 0 to ja.Size - 1 do
  begin
    jSubObj := (ja.Get(i) as TJSONObject);

    Memo2.Lines.Add(jSubObj.GetValue<string>(''name''));
    Memo2.Lines.Add(jSubObj.GetValue<string>(''quantity''));
    Memo2.Lines.Add(jSubObj.GetValue<string>(''price''));
    Memo2.Lines.Add(jSubObj.GetValue<string>(''subItemsPrice''));
    Memo2.Lines.Add(jSubObj.GetValue<string>(''totalPrice''));
    Memo2.Lines.Add(jSubObj.GetValue<string>(''discount''));
    Memo2.Lines.Add(jSubObj.GetValue<string>(''addition''));
    Memo2.Lines.Add(jSubObj.GetValue<string>(''externalCode''));
    Memo2.Lines.Add(jSubObj.GetValue<string>(''observations''));
  end;
end;

{
"items":[
{
"name":"Pastel de queijo",
"quantity":2,
"price":5.0,
"subItemsPrice":0,
"totalPrice":5.0,
"discount":0.0,
"addition":0.0,
"externalCode":"2222",
"subItems":[
{
"name":"Alface",
"quantity":1,
"price":1.5,
"totalPrice":1.5,
"discount":0.0,
"addition":0.0,
"externalCode":"13"
},
{
"name":"Bacon",
"quantity":1,
"price":3.0,
"totalPrice":3.0,
"discount":0.0,
"addition":0.0,
"externalCode":"11"
}
],
"observations":"SEM MAIONESE"
},
{
"name":"X-burguer bacon",
"quantity":1,
"price":8.0,
"subItemsPrice":4.5,
"totalPrice":12.5,
"discount":0.0,
"addition":0.0,
"externalCode":"7",
"subItems":[
{
"name":"Alface",
"quantity":1,
"price":1.5,
"totalPrice":1.5,
"discount":0.0,
"addition":0.0,
"externalCode":"13"
},
{
"name":"Bacon",
"quantity":1,
"price":3.0,
"totalPrice":3.0,
"discount":0.0,
"addition":0.0,
"externalCode":"11"
}
],
"observations":"SEM MAIONESE"
}
]
}
