Question

我有一个带参考的JSON模式。我正在尝试使用JsonSchemaResolver解决所有引用。但是，不幸的是，ref无法解析，并出现如下错误。

我正在尝试通过解析所有引用来获取替换的JSON。

代码：

        var schemaFileContents = File.ReadAllText(schemaFileName);
        JsonSchemaResolver resolver = new JsonSchemaResolver();
        var result = JsonSchema.Parse(schemaFileContents, resolver);
        Console.WriteLine(result);

JSON模式：

{
  "$schema": "YYYYYYY",
  "id": "XXXXXX",
  "title": "Current Employee Details",
  "description": "XXXXXXXXXXXXX",
  "type": "object",
  "properties": {
    "EMP": {
      "title": "Employee ",
      "description": "Details of the Employee",
      "$ref": "#/definitions/Employee"
    }},
    "definitions": {
      "EmployeeAddress": {
        "title": "Address",
        "description": "EmployeeAddress - Present Address",
        "type": "object",
        "properties": {
          "type": {
            "type": "string",
            "enum": [
              "EmployeeAddress"
            ]
          },
          "address": {
            "title": "Address",
            "type": "string"
          },
          "postalCode": {
            "title": "Postal Code",
            "type": "string"
          }
        },
        "required": [
          "postalCode",
          "address"
        ]
      },

      "Employee": {
        "title": "Party",
        "description": "Employee Details",
        "type": "object",
        "properties": {
          "firstName": {
            "title": "First name",
            "type": "string"
          },
          "address": {
            "title": "Employee Address",
            "$ref": "#/definitions/EmployeeAddress"
          }
        },
        "required": [
          "firstName"
        ]
      }
    }
  }

错误：

Answer 1

您似乎正在使用json schema V4，但是JsonSchemaResolver需要json schema V3。它们之间的区别在于required字段。尝试在属性级别使用bool值而不是更高级别的数组值来使用它：

"address": {
    "title": "Address",
    "type": "string",
    "required": true
}

根据docs JsonSchemaResolver已过时。要将json模式与最新标准一起使用，您需要使用separate package。使用JSchemaPreloadedResolver，请参见示例here

Answer 2

JsonSchemaResolver现在已弃用。请尝试以下操作，并使用Newtonsoft.Json.Schema NuGet

var schemaFileContents = File.ReadAllText(schemaFileName);
JSchemaPreloadedResolver resolver = new JSchemaPreloadedResolver();
var result = JSchema.Parse(schemaFileContents, resolver);
Console.WriteLine(result);

无法解析JSON模式并解析引用
