validate - Usando RegEx en el esquema JSON

json schema validator length

Question

Intentar escribir un esquema JSON que usa RegEx para validar un valor de un elemento.

Tenga un elemento llamado progBinaryName cuyo valor deba cumplir con esta cadena RegEx "^[A-Za-z0-9 -_]+_Prog//.(exe|EXE)$" .

No se pueden encontrar tutoriales o ejemplos que realmente expliquen el uso de RegEx en un esquema JSON.

Cualquier ayuda / información sería muy apreciada!

¡Advertencia! Mejor revisa tu JSON.

La instancia no es un tipo requerido - http://json-schema.org/draft-03/hyper-schema#

El esquema es JSON válido, pero no es un esquema válido.

Problem with schema#/properties/progBinaryName/patternProperties/progBinaryName : Instance is not a required type
Reported by http://json-schema.org/draft-03/hyper-schema#
Attribute "type" (["object"])

Answer 1

Para probar un valor de cadena (no un nombre de propiedad) contra un RegEx, debe usar la palabra clave "pattern" :

{
    "type": "object",
    "properties": {
        "progBinaryName": {
            "type": "string",
            "pattern": "^[A-Za-z0-9 -_]+_Prog//.(exe|EXE)$"
        }
    }
}

PD: si desea que el patrón coincida con la clave de la propiedad (no el valor), entonces debe usar "patternProperties" (es como "properties" , pero la clave es un RegEx).

Answer 2

Su sintaxis de esquema JSON es incorrecta. Cambio

"patternProperties": {
    "progBinaryName": "^[A-Za-z0-9 -_]+_Prog//.(exe|EXE)$"
    }

a

"patternProperties": {
    "^[A-Za-z0-9 -_]+_Prog//.(exe|EXE)$": {}
    }
