Похоже, что jsonschema версии 3.0.1 не принимает многоэтапную схему с использованием $ refs (хотя она работает с jsonschema версии 2.6.0).
Я должен заставить его работать под несколькими версиями модулей просто потому, что мой код будет работать на разных компьютерах в разных средах.
Я подтвердил свои jsons на https://www.jsonschemavalidator.net/ (спасибо за эту ссылку, найденную в другом вопросе StackOverflow).
Я пытался:
jsonschema -i myjson.json noRefs.schema.json --> 2.6.0 = OK, 3.0.1 OK
jsonschema -i myjson.json usingRefs.schema.json --> 2.6.0 = OK, 3.0.1 KO
Примечание:
Оба * .schema.json работали на https://www.jsonschemavalidator.net/
Файл myjson.json:
{
"TopProperty" : {
"LowerProperty" : {"toto" : "plop"}
}
}
Файл noRefs.schema.json:
{
"type": "object",
"properties": {
"TopProperty": {"$ref": "#/schemaTopProperty"}
},
"schemaTopProperty": {
"$id": "schemaTopProperty",
"type": "object",
"properties": {
"LowerProperty": {
"type": "object",
"properties": {
"toto": {"type": "string"}
}
}
}
}
}
Файл с использованием Refs.schema.json:
{
"type": "object",
"properties": {
"TopProperty": {"$ref": "#/schemaTopProperty"}
},
"schemaTopProperty": {
"$id": "schemaTopProperty",
"type": "object",
"properties": {
"LowerProperty": {
"type": "object",
"properties": {
"toto": {"$ref": "#/justAString"}
}
}
}
},
"justAString": {
"$id": "justAString",
"type": "string"
}
}
