API 测试实践中出现“com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException”错误。请指导我哪里错了？

Question

下面是我的主要代码。我正在尝试进行 POJO 反序列化的端到端流程。我还创建了必要的 getter 和 setter。我认为访问令牌正在生成，但之后它就停止了。我与另一个代码进行了交叉验证，但无法在我的代码中找到问题。请帮助我解决我出错的地方。

import static io.restassured.RestAssured.*;

import Pojo.getCourse;
import io.restassured.path.json.JsonPath;
public class oAuth {

    public static void main(String[] args) throws InterruptedException
    {
        try {
                String Response= given().formParam("client_id", "692183103107-p0m7ent2hk7suguv4vq22hjcfhcr43pj.apps.googleusercontent.com")
                .formParam("client_secret", "erZOWM9g3UtwNRj340YYaK_W")
                .formParam("grant_type", "client_credentials")
                .formParam("scope", "trust")
                .when().log().all()
                .post("https://rahulshettyacademy.com/oauthapi/oauth2/resourceOwner/token")
                .then().extract().asString();
                System.out.println(Response);
                
                //get access
                JsonPath js = new JsonPath(Response);
                String token=js.get("access_token");
                
                getCourse gc= given()
                .queryParam("access_token", token)
                .when().log().all()
                .get("https://rahulshettyacademy.com/oauthapi/getCourseDetails").as(getCourse.class);
                
                
                System.out.println(gc.getInstructor());
                System.out.println(gc.getUrl());

    }catch(Exception e) {
        e.printStackTrace();
        }
        
    }

}

这是输出：

我期待任何人的答复，但没有人帮助我。所以到目前为止我自己找到了它。 我发现在“getCourse”类中使用“@JsonIgnoreProperties(ignoreUnknown = true)”注释的1个解决方案，这有助于我解决错误。
