如何使用 Rest Assured 在 Response API 中获取两个具有相同名称的不同字段？

Question

我正在尝试使用 Rest-Assured 和 Java.

为 GET API 创建测试自动化

此 API 具有以下响应正文：

{
    "items": [
        {
            "id": "3185",
            "customer_id": "299",
            "region": "São Paulo",
            "region_id": 1234,
            "country_id": "BR",
            "street": [
                "Av Paulista"
            ],
            "company": "Teste",
            "telephone": "(19) 99999-9999",
            "postcode": "",
            "city": "Valinhos",
            "firstname": "N/A",
            "lastname": "N/A",
            "middlename": null,
            "prefix": null,
            "suffix": null,
            "person_type": "PF",
            "document": "43448871703",
            "state_registry": null,
            "created_at": "2019-07-24 13:03:29"
        },
        {
            "id": "3188",
            "customer_id": "299",
            "region": "São Paulo",
            "region_id": 1234,
            "country_id": "BR",
            "street": [
                "Av Paulista"
            ],
            "company": "Teste",
            "telephone": "(19) 99999-9999",
            "postcode": "",
            "city": "Valinhos",
            "firstname": "N/A",
            "lastname": "N/A",
            "middlename": null,
            "prefix": null,
            "suffix": null,
            "person_type": "PJ",
            "document": "84047942000115",
            "state_registry": null,
            "created_at": "2019-07-24 13:03:30"
        }
    ]
}

在此 API 响应中有两个同名字段 "id"。如何获取这两个字段的值？

谢谢

看看这篇文章：https://techeplanet.com/parse-json-array-using-rest-assured/

    @Test
    public void verifyJSONArrayResponse() {
        JsonArray jsonArray = new JsonArray();

        jsonArray = given().baseUri("http://<your host>")
                .basePath("<your path>")
                .get().as(JsonArray.class);

        for (int i = 0; i < jsonArray.size(); i++) {
            JsonObject jsonObject = jsonArray.get(i).getAsJsonObject();
            System.out.println(jsonObject.get("id").getAsString());
        }
    }

您需要稍微调整一下，首先从顶级响应对象中提取 items（您的数组）。

Answer 2

您可以使用 JsonPath 轻松做到这一点：$.items[*].id这将为您提供两个 ID。

Answer 3

由于您使用的是 REST-assured，您可以像这样直接从响应本身中提取您想要的内容：

List<Integer> = given()
                  .spec(yourRequestSpecification)
                  .get("/your_api_endpoint") // returns Response
                  .then()                    // returns ValidatableResponse
                  .extract()                 // returns ExtractableResponse
                  .path("items.id");         // Groovy GPath syntax

Jayway's jsonpath and REST-assured's jsonpath 使用不同的语法

Answer 4

您可以试试下面的代码。

import org.json.JSONArray;
import org.json.JSONException;
import org.testng.annotations.Test;

import bsh.ParseException;
import io.restassured.RestAssured;
import io.restassured.response.Response;
import io.restassured.specification.RequestSpecification;

public class KeyValueJsonArrayExample {

    @Test
    public void getResponseAsJsonArray() throws ParseException, JSONException {

        RequestSpecification myreq = RestAssured.given();

        Response MyRes;
        MyRes = myreq.get("http://localhost:3000/posts/");
        String jsonResponse = MyRes.asString();
        System.out.println("Full String is" + jsonResponse);

        JSONArray jsonArray = new JSONArray(jsonResponse);
        for (int i = 0; i < jsonArray.length(); i++) {
            org.json.JSONObject jsonObject1 = jsonArray.getJSONObject(i);
            String value1 = jsonObject1.optString("id");
            String value2 = jsonObject1.optString("auhtor");
            String value3 = jsonObject1.optString("title");
            System.out.println("The values are" + value1 + value2 + value3);
        }

    }

}

另外如果你只需要获取特定的索引，请尝试

Response response=given().contentType(ContentType.JSON).get("http://localhost:3000/posts");
        JsonPath jsonPathEvaluator = response.jsonPath();
        String title = jsonPathEvaluator.get("title[2]");
        String author=jsonPathEvaluator.get("author[2]");
