json - 请放心，使用 Gpath 查询会报错“参数“...”已使用但未定义。使用 JsonPath.params(...) 定义参数”

Question

我是新来的放心，我目前正在使用它以便在我们的测试框架中实现它。

我面临的问题是从 REST 响应中的 Json 数组中提取对象。

我正在使用的示例 json：

{
    "MRData": {
        "xmlns": "http://ergast.com/mrd/1.4",
        "series": "f1",
        "url": "http://ergast.com/api/f1/2016/drivers.json",
        "limit": "30",
        "offset": "0",
        "total": "24",
        "DriverTable": {
            "season": "2016",
            "Drivers": [
                {
                    "driverId": "alonso",
                    "permanentNumber": "14",
                    "code": "ALO",
                    "url": "http://en.wikipedia.org/wiki/Fernando_Alonso",
                    "givenName": "Fernando",
                    "familyName": "Alonso",
                    "dateOfBirth": "1981-07-29",
                    "nationality": "Spanish"
                },
                {
                    "driverId": "bottas",
                    "permanentNumber": "77",
                    "code": "BOT",
                    "url": "http://en.wikipedia.org/wiki/Valtteri_Bottas",
                    "givenName": "Valtteri",
                    "familyName": "Bottas",
                    "dateOfBirth": "1989-08-28",
                    "nationality": "Finnish"
                }
            ]
        }
    }
}

到目前为止我尝试过的事情：

这个断言有效

RestAssured.rootPath = "MRData.DriverTable.Drivers";
given()
.when()
.get("http://ergast.com/api/f1/2016/drivers.json")
.then()
.assertThat()
.body("find { find { d -> d.driverId == 'alonso' }.code }.code", equalTo("ALO"));

但我正在尝试实际获取特定数组项的 Json

RestAssured.rootPath = "MRData.DriverTable.Drivers";
given()
.when()
.get("http://ergast.com/api/f1/2016/drivers.json")
.then()
.extract()
//.jsonPath().param("driverId", "alonso").get("find { d -> d.driverId == driverId }");
.path("find { d -> d.driverId == 'alonso' }");

两种方式都试过（一种被注释掉了）。但我得到一个错误：

"The parameter "driverId" was used but not defined. Define parameters using the JsonPath.params(...)" 

Answer 1

RestAssured.rootPath = "MRData.DriverTable.Drivers";仅适用于身体期望。对于提取，您必须使用参数的完整路径，例如MRData.DriverTable.Drivers.find { it.@driverId == 'alonso' }
