使用json模式验证数组json包含几个无序对象 [英] validate array json contains several unordered objects using json schema

问题描述

我想使用json模式草稿7来验证数组包含几个无序对象.例如，数组应包含学生A，B，无论其顺序如何.

I want to use json schema draft 7 to validate that an array contains several unordered objects. For example, the array should contains student A, B, regardless of their orders.

[{"name": "A"}, {"name": "B"}] //valid
[{"name": "B"}, {"name": "A"}] //valid
[{"name": "A"}, {"name": "C"}, {"name": "B"}] //extra students also valid
[] or [{"name": "A"}] or [{"name": "B"}] //invalid

当前尝试

json模式contains关键字不支持列表

Current Attempt

json schema contains keyword doesn't support a list

json模式Tuple validation关键字必须排序

json schema Tuple validation keyword must be ordered

推荐答案

您需要allOf应用程序关键字.您需要定义多个contains子句.

You want the allOf applicator keyword. You need to define multiple contains clauses.

allOf允许您定义必须全部通过的多个模式.

allOf allows you to define multiple schemas which must all pass.

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "allOf": [
    {
      "contains": {
        "required": ["name"],
        "properties": {
          "name": {
            "const": "A"
          }
        }
      }
    },
    {
      "contains": {
        "required": ["name"],
        "properties": {
          "name": {
            "const": "B"
          }
        }
      }
    }
  ]
}
