对于具有递归$ ref的JSONSchema，ajv验证失败

Question

我使用“ajv”：“^ 6.5.1”进行JSONSchema验证。提到的JSONSchema具有adressInfo字段的递归引用，这是必填字段。

我收到验证失败错误：

[{ “关键字”： “需要”， “数据路径”： “billing_address.adressInfo.adressInfo”， “schemaPath”： “＃/需要”， “PARAMS”：{ “missingProperty”： “STREET_ADDRESS”}， “消息” ：“应该有必需的属性'street_address'”}]

我应该为这种类型的JSONSchema做什么，因为它需要每个级别的adressInfo。这是我的脚本：

var Ajv = require('ajv');

var addressJsonSchema = {
    "$schema": "http://json-schema.org/draft-07/schema#",
    "additionalProperties": false,
    "definitions": {
        "address": {
            "type": "object",
            "properties": {
                "street_address": {
                    "type": "string"
                },
                "city": {
                    "type": "string"
                },
                "adressInfo": {
                    "$ref": "#/definitions/address"
                }
            },
            "required": ["street_address", "city", "adressInfo"]
        }
    },
    "type": "object",
    "properties": {
        "billing_address": {
            "$ref": "#/definitions/address"
        }
    }
}

var ajv = new Ajv({
    schemaId: '$id',
    meta: false,
});

var metaSchema = require('../node_modules/ajv/lib/refs/json-schema-draft-07.json');
ajv.addMetaSchema(metaSchema);
ajv._opts.defaultMeta = metaSchema.$id;

var inputData = {
    "billing_address": {
        "street_address": "Viman Nagar",
        "city": "pune",
        "adressInfo": {
            "street_address": "Chandan Nagar",
            "city": "pune",
            "adressInfo": {}
        }
    }
}
try {
    var validate = ajv.compile(addressJsonSchema);
    var valid = validate(inputData);
    if (!valid) {
        console.log('Validation failed error:');
        console.log(JSON.stringify(validate.errors));
    } else {
        console.log("successfully done validation");
    }
} catch (e) {
    console.log(e);
}
