java - 使用 REST Assured，我如何验证 Json 对象数组中的数据类型

问题描述

我是 Rest Assured 的新手，并尝试使用 json-schema-validator version-4.3.0 进行一些验证。运行时出错。在这方面需要帮助。

这是我的架构（sample.json）：

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "type": "object",
  "properties": {
    "title": {
      "type": "string"
    },
    "subTitle": {
      "type": "string"
    },
    "author": {
      "type": "string"
    },
    "publish_date": {
      "type": "string"
    },
    "publisher": {
      "type": "string"
    },
    "pages": {
      "type": "number"
    },
    "Description": {
      "type": "string"
    },
    "Website": {
      "type": "string"
    }
  },
  "required": ["title", "subTitle", "author", "publish_date", "publisher", "pages", "Description", "Website"]
}

我的 json 响应是这样的：

{
  "books": [
    {
      "isbn": "9781449325862",
      "title": "Git Pocket Guide",
      "subTitle": "A Working Introduction",
      "author": "Richard E. Silverman",
      "publish_date": "2020-06-04T08:48:39.000Z",
      "publisher": "O'Reilly Media",
      "pages": 234,
      "description": "This pocket guide is the perfect on-the-job companion to Git, the distributed version control system. It provides a compact, readable introduction to Git for new users, as well as a reference to common commands and procedures for those of you with Git exp",
      "website": "http://chimera.labs.oreilly.com/books/1230000000561/index.html"
    }
}

编写的测试用例是：

public class AppTest {
 
    @Test
    public void verifyJsonSchema() {
        

        // GIVEN
        RestAssured
            .given()
                .baseUri("https://bookstore.toolsqa.com/BookStore/v1/Books/9781449325862")
        // WHEN
            .when()
                .get()
        // THEN
            .then()
                .assertThat()
                .statusCode(200)
                .body(JsonSchemaValidator.matchesJsonSchemaInClasspath("sample.json"));
    }
 
}

我/我得到的错误是：

另外，我想知道是否可以验证不同的数据类型，如字符、日期、数字？如果是，那么也请帮助我。

提前致谢...

解决方案

您的架构是错误的。您可以使用此架构。

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "type": "object",
  "properties": {
    "books": {
      "type": "array",

              "type": "string"
            },
            "title": {
              "type": "string"
            },

            },

            },
            "publisher": {
              "type": "string"

            "description": {
              "type": "string"

            "website": {

json中有6种数据类型：数字、字符串、数组、对象、布尔值、空值。您无法验证字符、日期时间...
