Estoy queriendo proveer un servicio REST que soporte indistintamente estos
2 JSON:
{
    "Var1": 3,
    "Var2": "HOLA",
    "SDT1": {
        "Var3": "",
        "Var4": "",
        "Var5": ""
    }
}
y
{
    "Var1": 3,
    "Var2": "HOLA",
    }
}
Cuando invoco la opcion 1 funciona sin problema, tambien funciona si invoco:
{
    "Var1": 3,
    "Var2": "HOLA",
    "SDT1": {
    }
}
Pero si evito la cabecera del SDT me da este error:

Hola Osmar, Así funciona la validación en rest. Tu alternativa sería recibir un parámetro de entrada de tipo STRING pIN con formato JSON, que luego deberías importar asi: SDT.fromstring( pIN ) De esta forma te funcionaria de ambas maneras: 1. Incluyendo la definición del SDT 2. Sin hacer referencia al SDT. Saludos, Alberto Fernandez El lun, 22 mar 2021 a las 22:04, Osmar Gerke ()

Hola Osmar. Puedes crear una SDT que contenga las dos SDT y un campo donde envias un valor que te referencie si es una u otra estructura la que tienes valores. { "tipo":"1", { "Var1": 3, "Var2": "HOLA", "SDT1": { "Var3": "", "Var4": "", "Var5": "" } } { "Var1": 3, "Var2": "HOLA", } } Me comentas como te fue.
