Question

此JSON文件应该无法通过验证，但事实并非如此。有人告诉我原因。

将以下json数据和架构插入此网站，验证，
http://json-schema-validator.herokuapp.com 我在Mule Validate JSON Schema中得到了相同的结果。它显然不符合架构（我添加了一些字段，我拼错了一些字段，日期时间值不是真正的日期时间），但它不会失败。有人可以告诉我为什么吗？

JSON架构：

{

        "sourceSystem"
      ],

Answer 1

它不会失败，因为您的架构不强制执行任何约束。请注意，definitions不是约束验证的jsonschema关键字。它通常用于放置在模式定义的其他部分中重用的子模式。因此，首先，您应该更改definitions的{{1}}关键字。

properties的另一个常见误解与jsonschema关键字有关。我们来看以下示例：

properties

您必须将其读作：{ "type" : "object", "properties" : { "key1" : { "type" : "string" } } }必须是对象，如果它包含等于json的键，则其值必须是字符串。根据以下两个json对象是有效的：

key1

和

{
    "key2":12
}

最后，与{ "key1":"sdf" }格式相关，您必须检查section 6 of RFC3339以确保您拥有有效的日期时间。在任何情况下，date-time验证器都不强制执行格式。

谢谢@jruizaranguren我也知道我需要放置 “additionalProperties”：false和“required”：确保在API中传递的内容是预期的。

以下是我解决问题的方法。

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "type": "object",
  "definitions": {
    "serviceAuditLogData": {
      "type": "object",
      "additionalProperties": false,
      "required": [
        "auditCorrelationId",
        "serviceRequestTimestamp",
        "serviceProvider",
        "serviceProviderVersion",
        "serviceProviderTimestamp",
        "eventType",
        "hostName",
        "sourceSystem",
        "authenticationId"
      ],
      "properties": {
        "auditCorrelationId": {
          "type": "string"
        },
        "serviceRequestTimestamp": {
          "type": "string",
          "format": "date-time"
        },
        "serviceProvider": {
          "type": "string"
        },
        "serviceProviderVersion": {
          "type": "string"
        },
        "serviceProviderTimestamp": {
          "type": "string",
          "format": "date-time"
        },
        "eventType": {
          "type": "string"
        },
        "eventDetail": {
          "type": "string"
        },
        "hostName": {
          "type": "string"
        },
        "sourceSystem": {
          "type": "string"
        },
        "authenticationId": {
          "type": "string"
        },
        "endUserId": {
          "type": "string"
        },
        "inputData": {
          "type": "string"
        }
      }
    }
  },
  "additionalProperties": false,
  "required": [
    "serviceAuditLogData"
  ],
  "properties": {
    "serviceAuditLogData": {
      "$ref": "#/definitions/serviceAuditLogData"
    }
  }
}
