【问题描述】：

如何将以下对象转换为有效的 JSON 架构？我在实现使用rest-assured 的工具时需要它。

{
  "page": 2,
  "per_page": 3,
  "total": 12,
  "total_pages": 4,
  "data": [{
      "id": 4,
      "first_name": "Eve",
      "last_name": "Holt",
      "avatar": "https://s3.amazonaws.com/uifaces/faces/twitter/marcoramires/128.jpg"
    },
    {
      "id": 5,
      "first_name": "Charles",
      "last_name": "Morris",
      "avatar": "https://s3.amazonaws.com/uifaces/faces/twitter/stephenmoon/128.jpg"
    },
    {
      "id": 6,
      "first_name": "Tracey",
      "last_name": "Ramos",
      "avatar": "https://s3.amazonaws.com/uifaces/faces/twitter/bigmancho/128.jpg"
    }
  ]
}

这里是您可以在线生成 JSON Schema Draft V4 Schemas 的链接

JSON Schema Generator Online

这是生成的 JSON 模式。您可以根据您的要求更改所需的块

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "type": "object",
  "properties": {
    "page": {
      "type": "integer"
    },
    "per_page": {
      "type": "integer"
    },
    "total": {
      "type": "integer"
    },
    "total_pages": {
      "type": "integer"
    },
    "data": {
      "type": "array",
      "items": [
        {
          "type": "object",
          "properties": {
            "id": {
              "type": "integer"
            },
            "first_name": {
              "type": "string"
            },
            "last_name": {
              "type": "string"
            },
            "avatar": {
              "type": "string"
            }
          },
          "required": [
            "id",
            "first_name",
            "last_name",
            "avatar"
          ]
        }
      ]
    }
  },
  "required": [
    "page",
    "per_page",
    "total",
    "total_pages",
    "data"
  ]
}

一旦你有了 JSON 和 Schema，你就可以放心地测试了，如下所示

@Test(enabled=true)
    public void schemaValidation() {

            RestAssured.given().get("http://localhost:8080/endpoint")
                    .then().assertThat().body(matchesJsonSchemaInClasspath(System.getProperty("user.dir")+File.separator+"resources"+File.separator+"JsonSchemas"+File.separator+"SampleSchema.json"));

    }

或者您有如下自定义验证

@Test(enabled=true)
    public void schemaValidation2() throws IOException, ProcessingException {

           Response response =  RestAssured.given().get("http://localhost:8080/endpoint")
                    .andReturn();

           com.github.fge.jsonschema.main.JsonSchema schemaFileJson = ValidationUtils.getSchemaNode(System.getProperty("user.dir")+File.separator+"resources"+File.separator+"JsonSchemas"+File.separator+"SampleSchema.json");
            ObjectMapper mapper = new ObjectMapper();
            com.fasterxml.jackson.databind.JsonNode responseBodyJsonObject = mapper.readTree(response.getBody().asString());


            if(schemaFileJson.validate(responseBodyJsonObject).isSuccess()) {
                System.out.println("Schema is valid");
            }else {
                System.out.println("Schema is not valid");
            }

    }
