rest-assured - 从 Rest Assured 响应中提取嵌套值

Question

我需要针对以下 json 响应正文中“字段”(即“同意”、“失败计数”)下的值进行提取和/或断言:

{
"next": null,
"previous": null,
"results": [
    {
        "huid": "be7d-794186bda2d3",
        "name": null,
        "language": "eng",
        "arns": [
            "doodle:123456"
        ],
        "groups": [],
        "fields": {
            "consent": "TRUE",
            "failure_count": 2,
            "timestamp": "2020-04-17T12:04:04.978887Z",
            "registration_type": "normal"
        },
        "blocked": false,
        "stopped": false,
        "created_on": "2020-04-17T12:04:04.978887Z",
        "modified_on": "2020-04-17T12:04:05.692949Z"
    }
]

Answer 1

如果您希望结果为数组，您可以创建 pojo 类。例如:

public class ExampleResponse {
    private Object next;
    private Object previous;
    private Result[] results;

    //add getters and setters

    public class Result {
        private String huid;
        private String name;

        //add getters and setters
    }
}

然后将您的 json 响应转换为 java 对象

ExampleResponse pojo = given()
    .when().get(endpoint)
    .then().extract().body().as(ExampleResponse.class);

在此操作之后，您可以提取和/或断言任何字段。例如:

...
results[0].isBlocked();
...

您也可以尝试使用路径方法提取字段值:

...
given()
    .when().get(endpoint)
    .path("results[0].arns[0]");

...

given()
    .when().get(endpoint)
    .path("results[0].fields.timestamp");
...

如果你期望通常的 json(没有结果作为数组)，你可以使用这个方法:

//assert value
given()
    .when().get(endpoint)
    .then()
    .assertThat()
    .body("result.name", equalTo(someName));

//assert response has or not parameter
given()
    .when().get(endpoint)
    .then()
    .body("results", hasKey("name"))
    .body("results", not(hasKey("name")));
