ViewsHow to validate property field which is UUID in json schema?
{
"status": 200,
"id": "123e4567-e89b-12d3-a456-426655440000",
"shop": {
"c73bcdcc-2669-4bf6-81d3-e4ae73fb11fd": {
"123e4567-e89b-12d3-a456-426655443210": {
"quantity": {
"value": 10
}
},
"123e4567-e89b-12d3-a456-426655443211": {
"quantity": {
"value": 20
}
}
}
}
}
This is my json response. I want to validate the fields "c73bcdcc-2669-4bf6-81d3-e4ae73fb11fd" , "123e4567-e89b-12d3-a456-426655443210" and "123e4567-e89b-12d3-a456-426655443211", which are uniquely generated every time whenever hits the endpoint.

To validate in JSON schema that a string conforms to a regular expression pattern use
{ "type": "string", "pattern": "\b[0-9a-f]{8}\b-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-\b[0-9a-f]{12}\b" }
The concrete pattern is adapted from the question Searching for UUIDs in text with regex see there for more details.
To validate UUID in particular, you may use format in JSON schema, which provides built-in support for the UUID syntax: { "type": "string", "format": "uuid" }
See https://json-schema.org/understanding-json-schema/reference/string.html

You need "patternProperties":
{
"$schema":"http://json-schema.org/draft-07/schema#",
"type":"object",
"properties": {
"shop":{
"type":"object",
"additionalProperties":false,
"patternProperties":{
"[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}": {
"type":"object",
"patternProperties" :{
"[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}":{
"type":"object",
"properties":{
"quantity":{
"type":"object",
"properties":{
"value":{
"type":"integer"
}
}
}
}
}
}
}
}
}
}
}

Building on @pxcv7r's answer:

See https://json-schema.org/understanding-json-schema/reference/string.html
Additionally, you can use a combination of "propertyNames" and "unevaluatedProperties" to avoid the need for any regular expression:
{
"$schema": "https://json-schema.org/draft/2019-09/schema",
"type": "object",
"properties": {
"status": {
"type": "integer"
},
"id": {
"type": "string",
"format": "uuid"
},
"shop": {
"type": "object",
"minProperties": 1,
"maxProperties": 1,
"propertyNames": {
"format": "uuid"
},
"unevaluatedProperties": {
"type":"object",
"minProperties": 1,
"propertyNames": {
"format": "uuid"
},
"unevaluatedProperties": {
"title": "single variant of a shop",
"type": "object",
"properties": {
"quantity": {
"type": "object",
"properties": {
"value": {
"type": "integer"
}
}
}
}
}
}
}
}
}
