Question

我是REST Assured API测试的新手，我已经在库中添加了jackson-databind，jackson-annotations和jackson-core所有2.9.6版本。

下面是我的代码：

public class SerializeAndDeserialize {

    @Test
    public void RegistrationSuccessful()
    {   

        RestAssured.baseURI ="http://restapi.demoqa.com/customer";
        RequestSpecification request = RestAssured.given();

        JSONObject requestParams = new JSONObject();
        requestParams.put("FirstName", "Virkjdender"); // Cast
        requestParams.put("LastName", "Scklxjingh");
        requestParams.put("UserName", "63userf2d3cn,mxd2011");
        requestParams.put("Password", "passwors000mxzmd1"); 
        requestParams.put("Email",  "ed26dfdasdf39@gmail.com"); 


        request.body(requestParams.toJSONString());
        Response response = request.post("/register");

        ResponseBody body = response.getBody();
        System.out.println(response.body().asString());
        System.out.println(response.contentType());
        System.out.println(response.getStatusCode());       

        if(response.statusCode() == 200)
        {
            // Deserialize the Response body into RegistrationFailureResponse
            RegistrationFailureResponse responseBody = body.as(RegistrationFailureResponse.class);   
            Assert.assertEquals("User already exists", responseBody.FaultId);
            Assert.assertEquals("FAULT_USER_ALREADY_EXISTS", responseBody.fault);   
        }
        else if (response.statusCode() == 201)
        {
            // Deserialize the Response body into RegistrationSuccessResponse
            RegistrationSuccessResponse responseBody = body.as(RegistrationSuccessResponse.class);          
            Assert.assertEquals("OPERATION_SUCCESS", responseBody.SuccessCode);
            Assert.assertEquals("Operation completed successfully", responseBody.Message);  
        }   
    }
}

相关类如下：

public class RegistrationFailureResponse {  
    @JsonIgnoreProperties(ignoreUnknown = true) 

    String FaultId;
    String fault;   
}

另一个：

public class RegistrationSuccessResponse {  
    @JsonIgnoreProperties(ignoreUnknown = true)

    public String SuccessCode;   
    public String Message;
}

当我尝试通过Testng.xml文件运行以上代码时，出现以下错误：

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException：无法识别的字段“ FaultId”（类RegistrationFailureResponse），未标记为可忽略（0个已知属性：]）在[来源：（字符串）” { “ FaultId”：“用户已经存在”， “故障”：“ FAULT_USER_ALREADY_EXISTS” }“；第2行，第17列]（通过参考链：RegistrationFailureResponse [” FaultId“]）在com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException.from（UnrecognizedPropertyException.java:60）在com.fasterxml.jackson.databind.DeserializationContext.handleUnknownProperty（DeserializationContext.java:822）在com.fasterxml.jackson.databind.deser.std.StdDeserializer.handleUnknownProperty（StdDeserializer.java:1152）在com.fasterxml.jackson.databind.deser.BeanDeserializerBase.handleUnknownProperty（BeanDeserializerBase.java:1589）在com.fasterxml.jackson.databind.deser.BeanDeserializerBase.handleUnknownVanilla（BeanDeserializerBase.java:1567）在com.fasterxml.jackson.databind.deser.BeanDeserializer.vanillaDeserialize（BeanDeserializer.java:294）在com.fasterxml.jackson.databind.deser.BeanDeserializer.deserialize（BeanDeserializer.java:151）在com.fasterxml.jackson.databind.ObjectMapper._readMapAndClose（ObjectMapper.java:4013）在com.fasterxml.jackson.databind.ObjectMapper.readValue（ObjectMapper.java:3042）在com.fasterxml.jackson.databind.ObjectMapper $ readValue $ 0.call（未知源）在org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall（CallSiteArray.java:48）在org.codehaus.groovy.runtime.callsite.AbstractCallSite.call（AbstractCallSite.java:113） ......

请帮助，我用谷歌搜索了解决方案，但都与我在这里面临的问题无关

实际上，您不应该忽略未知属性，因为没有属性。响应正是您所期望的：

{ 
  "FaultId": "User already exists",
  "fault": "FAULT_USER_ALREADY_EXISTS"
}

但是您的响应类配置错误。尝试使用@JsonProperty注释字段。

public class RegistrationFailureResponse {

    @JsonProperty private String FaultId;
    @JsonProperty private String fault;
}

在REST的保障中，将响应映射到对象时如何解决UnrecognizedPropertyException？
