使用 RestAssured 验证模式。 InvalidSchemaException：致命：无效 JSON 架构，无法继续

Question

我正在尝试使用 Rest Assured 验证响应模式并遇到错误。它显示验证期望一个字符串作为 ID，但它返回整数。其次，它跳过了模型中的许多字段，我想知道为什么。我如何获得架构验证。

这是我在验证模式时使用的代码

@Test(priority = 1)
    public static void searchForUsername( ) throws Throwable {
        Response response = RestAssured.given().queryParam(getProperties().getProperty("project.query"), getProperties().getProperty("project.username"))
                .get(Init.initProperties() +getProperties().getProperty("users.pathURL"));
        response.then().assertThat().body(matchesJsonSchemaInClasspath("schema/users.json")).contentType(ContentType.JSON).statusCode(200).log().all();
        List<UserItem> userItems = response.as(new TypeRef<>() {});
        for ( UserItem u: userItems ) {
            if ( (Integer) response.jsonPath().getList("id").get(0) == u.getId() ){
                userId = u.getId();
                MyLogger.info("This is getting the user ID of Delphine " + userId);
            }
        }
    }

这是架构。这是 users.json

{
    "id": 9,
    "name": "Glenna Reichert",
    "username": "Delphine",
    "email": "Chaim_McDermott@dana.io",
    "address": {
      "street": "Dayna Park",
      "suite": "Suite 449",
      "city": "Bartholomebury",
      "zipcode": "76495-3109",
      "geo": {
        "lat": "24.6463",
        "lng": "-168.8889"
      }
    },
    "phone": "(775)976-6794 x41206",
    "website": "conrad.com",
    "company": {
      "name": "Yost and Sons",
      "catchPhrase": "Switchable contextually-based project",
      "bs": "aggregate real-time technologies"
    }
  }

模式验证错误。

Answer 1

我认为错误信息很清楚：

"message" : "value has incorrect type (found integer, expected one of [string])",

正如您在 json 中看到的那样，id 是一个整数

{
"id": 9,
..
}

解决方法如下：

检查你的架构，某处有一个声明 id 是一个字符串，而不是一个整数
将此声明更改为整数
运行再次，应该工作

注意：我不知道json中的数据是否真实，在将生产数据复制粘贴到SO[=12之前仔细检查=]

我经常用这个工具来生成schema，可以节省很多时间。 https://www.liquid-technologies.com/online-json-to-schema-converter
