JSON模式-如何在对象递归中定义对象

Question

Situation is following:

1.) In an object, I can have a "string", "array" or another "object".

2.) The "array" can contain only "string".

3.) The "object" can contain 1.) which means that I can have an object in a object which only can have a string or array though (or even more nested objects)

Problem is now that 1.) and 2.) work but as soon as I add "$ref" to the "object" to get 3.) my validation server crashes with a stack overflow.

{
  "$schema": "http://json-schema.org/draft-04/schema",
  "type": "object",
  "properties": {
    "value": {
      "oneOf": [
        {
          "type": "string"
        },
        {
          "type": "array",
          "items": {
            "type": "string"
          }
        },
        {
          "type": "object",
          "patternProperties": {
            ".*": {
              "$ref": "#/properties/value"
            }
          }
        }
      ]
    }
  }
}

The line "$ref": "#/properties/value" breaks my code.

How do I get this to work ?

Answer 1

Fixed it myself. The line "$ref": "#/properties/value" has to be changed to "$ref": "#/properties"

I thought that #/properties would mean only the property "value" is allowed inside these objects which is not what I wanted. I wanted to have the contents of "value" so I went one step deeper.

Looks like "$ref": "#/properties" doesn't mean that only "value" is allowed instead it means only the properties of "value".
