当必需字段为空字符串时，JSON 模式不验证该字段

Question

我正在使用 mule 验证 JSON 架构组件来验证传入的 json 请求。它验证类型但不验证必需的字段属性

{
  "type": "object",
  "$schema": "http://json-schema.org/draft-04/schema",
  "properties": {
    "Employees": {
      "type": "array",
      "minItems": 1,
      "items": {
        "type": "object",
        "properties": {
          "BirthDate": {
            "type": "string",
            "format": "date-time"
          },
          "EmpNum": {
            "type": "number"
          },
          "FirstName": {
            "type": "string"
          },
          "Gender": {
            "type": "string"
          },
          "LastName": {
            "type": "string"
          },
          "LicenseNumber": {
            "type": "string"
          },
          "ZipCode": {
            "type": "string"
          }
        },
        "required": ["EmpNum", "LastName", "FirstName", "Street", "ZipCode", "BirthDate" ]
      }
    }
  }
}

我有 json 如下所示：

{
  "Employees": [
    {
      "EmpNum": 3,
      "FirstName": "Finder",
      "LastName": "Path",
      "Street": "392 CDI CDIJUW",
      "ZipCode": "12345",
      "BirthDate": "1943-05-19T04:00:00Z",
      "Gender": "M"
    },
    {
       "EmpNum": 3,
      "FirstName": "",
      "LastName": "Path",
      "Street": "392 CDI CDIJUW",
      "ZipCode": "12345",
      "BirthDate": "1943-05-19T04:00:00Z",
      "Gender": "M"
    }
  ]
}

尽管我已将字段设置为空字符串，但它仍然视为有效请求并进一步继续。

如果您故意将 FirstName 设置为空字符串并希望使其无效，请尝试添加 minLength：

      "FirstName": {
        "type": "string",
        "minLength": 1
      },
