JSON validates optional parameter using schema

Question

I want to check json input through json scheme. A positive case works for intended objects and properties. But I want to check for additional objects, parameters that are not mentioned in the circuit.

Basically, fails to check if junk data was detected in json

Answer 1

If you want to have only a specific set of properties in JSON objects and refuse to others:

• make sure you have the appropriate schema in properties and patternProperties ,

• define additionalProperties - false :

   { "type": "object", "properties": { "p": {}, "q": {} }, "additionalProperties": false } 

will only allow p and q in instances of objects.
