在 jsonschema 中使用负后视

Question

我正在使用 Node 9.2.0 和 ajv 6.0.0。

我有一个模式，我希望在其上使用负面回顾，它的定义如下：

{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "title": "release format",
    "description": "A Release Format",
    "type": "object",
    "properties": {
        "id": {"type": "integer"},
        "title": {
            "anyOf": [
                {
                    "type": "string",
                    "pattern": "^((?!itunes).)*$"
                },
                {
                    "type": "string",
                    "pattern": "^((?!exclusive).)*$"
                },
                {
                    "type": "string",
                    "pattern": "^((?!ringtone).)*$"
                }
            ]
        }
    }
}

但是，当我尝试使用以下数据通过 AJV 对其进行验证时：{"id": 123, "title": "world exclusive"} 我没有收到验证错误。

代码：

const Ajv = require('ajv');
class Validator {
  constructor() {
    this.releaseFormatSchema = JSON.parse(fs.readFileSync('./schemas/release-format.json'));
    this.schemaValidator = new Ajv({allErrors: true});
  }

  validate(data) {
    let validate = this.schemaValidator.compile(this.releaseFormatSchema);
    let valid = validate(data);
    console.log(valid);
    console.log(validate);
  }
}

其中数据为：{"id": 123, "title": "world exclusive"}。我希望这会出错，但它目前告诉我数据有效。

Answer 1

@sln 和@ClasG 也找到了答案，anyOf does a union between titles patterns can match : "all except strings which contains itunes" union "all except strings which contains exclusive" union "...", which means all which not包含所有禁止的关键字。也可以修复

使用 allOf 而不是 anyOF

"title": {
    "allOf": [
        {
            "type": "string",
            "pattern": "^((?!itunes).)*$"
        },
        {
            "type": "string",
            "pattern": "^((?!exclusive).)*$"
        },
        {
            "type": "string",
            "pattern": "^((?!ringtone).)*$"
        }
    ]
}

使用单个 type/pattern :

"title": {
    "type": "string",
    "pattern": "^((?!itunes|exclusive|ringtone).)*$"
}
