有一些json。

{
  "headerInfo": {
    "id": 50
  "characteristics": [
    {
      "id": "123456789",
      "type": "float",
      "multiValued": false,
      "numberDecimals": 6,
      "length": 10,
      "caseSensitive": false,
      "entryFieldMask": "_,___.______",
      "unitOfMeasure": "P1",
      "additionalValues": true
    },
    {
      "id": "15151511",
      "type": "float",
      "multiValued": false,
      "numberDecimals": 0,
      "possibleValues": [
        {
          "valueLow": "60",
          "intervalType": "1"
        },
        {
          "valueLow": "80",
          "intervalType": "1"
        }
      ],
      "length": 3,
      "caseSensitive": false,
      "entryFieldMask": "___",
      "unitOfMeasure": "P1",
      "additionalValues": false
    },
    {
      "id": "489481561",
      "type": "string",
      "multiValued": false,
      "possibleValues": [
        {
          "id": "A"
        }
        {
          "id": "§"
        }
      ],
      "length": 1,
      "caseSensitive": true,
      "entryFieldMask": "",
      "additionalValues": false,
      "reference": {
        "name": "ghnfgjghjghk",
        "writable": false
      }
    },
    {
      "id": "4616616161",
      "type": "date",
      "multiValued": false,
      "length": 10,
      "caseSensitive": false,
      "entryFieldMask": "DD.MM.YYYY",
      "additionalValues": true,
      "reference": {
        "name": "bfhwbvbjewbv",
        "writable": false
      }
    }
  ]
}

如何使用以下条件生成json schema：

“reference”和“possibleValues”属性是可选的。
如果“type”属性等于“float”值，则需要“numberDecimals”属性，否则不需要。

我尝试使用anyOf实现这一点，但在这种情况下，anyOf中的所有内容都没有被正确验证，尽管在postman中验证是成功的。

Jeremy的回答很有帮助，但还需要进一步完善，即在oneOf中添加“required”属性。以下是最终结果：

您可以将if, then语法用于JSON Schema draft-07或更新版本。
jist是你定义整个模式，然后在你想要定义required属性的对象模式中，你添加if, then语法来检查值是否匹配条件，然后分配then约束。
在你的例子中，我们检查if，type的常数值是float，如果为真，则为required:["numberDecimals"]
