Java 在 REST Assured 中，如何检查响应中是否存在字段？

In REST Assured, how can I check if a field is present or not in the response?

提问by juliaaano

How can I make sure that my response, let's say it is in JSON, either containsor does not containa specific field?

我如何确保我的响应（假设它是 JSON 格式）包含或不包含特定字段？

when()
    .get("/person/12345")
.then()
    .body("surname", isPresent()) // Doesn't work...
    .body("age", isNotPresent()); // ...But that's the idea.

I'm looking for a way to assert whether my JSON will contain or not the fields ageand surname.

我正在寻找一种方法来断言我的 JSON 是否将包含字段age和surname。

You can use equals(null) like this:

您可以像这样使用 equals(null) ：

.body("surname", equals(null))

.body("surname", equals(null))

If the field does not exists it will be null

如果该字段不存在，它将为空

Check whetever field is null. For example:

检查无论字段是否为空。例如：

    Response resp = given().contentType("application/json").body(requestDto).when().post("/url");
    ResponseDto response = resp.then().statusCode(200).as(ResponseDto.class);
    Assertions.assertThat(response.getField()).isNotNull();

You can use the Hamcrest matcher hasKey()(from org.hamcrest.Matchersclass) on JSON strings as well.

您也可以在 JSON 字符串上使用 Hamcrest 匹配器hasKey()（来自org.hamcrest.Matchers类）。

when()
    .get("/person/12345")
.then()
    .body("$", hasKey("surname"))
    .body("$", not(hasKey("age")));

Using: import static org.junit.Assert.assertThat;

使用： import static org.junit.Assert.assertThat;

Your could then: assertThat(response.then().body(containsString("thingThatShouldntBeHere")), is(false));

你可以： assertThat(response.then().body(containsString("thingThatShouldntBeHere")), is(false));
