[英]How get size of an array in json response? rest assured API, JAVA
I found a lot of topics with this question on this portal, but anyway I was not able to achieve what I need.我在这个门户网站上找到了很多关于这个问题的主题,但无论如何我都无法实现我所需要的。 I keep getting the next exception:
java.lang.IllegalArgumentException: The parameter "roles" was used but not defined. Define parameters using the JsonPath.params(...) function
我不断收到下一个异常:
java.lang.IllegalArgumentException: The parameter "roles" was used but not defined. Define parameters using the JsonPath.params(...) function
java.lang.IllegalArgumentException: The parameter "roles" was used but not defined. Define parameters using the JsonPath.params(...) function
. java.lang.IllegalArgumentException: The parameter "roles" was used but not defined. Define parameters using the JsonPath.params(...) function
。
Partially my code:部分我的代码:
import static io.restassured.RestAssured.given;
import io.restassured.RestAssured;
import io.restassured.path.json.JsonPath;
import io.restassured.response.Response;
String baseURItest = RestAssured.baseURI = "http://testapi.test.com/testapps");
Response response;
response = given().when().get("/getAllRoles?token=token");
countRoles=response.body().path("$..roles.size()");
System.out.println(countRoles);
console output:控制台输出:
> java.lang.IllegalArgumentException: The parameter "roles" was used but
> not defined. Define parameters using the JsonPath.params(...) function
and json body response:和 json 正文响应:
{
"Message": "",
"Status": 200,
"Data": {
"errors": [],
"roles": [
{
"ROLEKEY": "1",
"ROLEID": 1,
"ROLENAME": "name1",
"ROLEDESCRIPTION": "1"
},
{
"ROLEKEY": "2",
"ROLEID": 2,
"ROLENAME": "name2",
"ROLEDESCRIPTION": "12"
},
{
"ROLEKEY": "3",
"ROLEID": 3,
"ROLENAME": "name3",
"ROLEDESCRIPTION": "x"
}
]
}
}
I also tried :我也试过:
JsonPath jsonPathValidator = response.jsonPath(); System.out.println(jsonPathValidator.get("$..ROLEKEY").toString());
I would say I tried a lot of different ways that I found in google, but each time I will get the same error.我会说我尝试了很多在 google 中找到的不同方法,但每次都会遇到相同的错误。 Can someone please explain to me what am I missing here, please?
有人可以向我解释我在这里缺少什么吗? Or what should I do?
或者我该怎么办? Thank you in advance for any help!
预先感谢您的任何帮助!
Problem: You misunderstand JsonPath in Rest-Assured.问题:您误解了 Rest-Assured 中的 JsonPath。
$..ROLEKEY
is JsonPath jayway syntax. $..ROLEKEY
是JsonPath jayway语法。
JsonPath in Rest-Assured uses groovy GPath internally. Rest-Assured 中的 JsonPath 在内部使用 groovy GPath 。
Note from Rest-Assured wiki .来自 Rest-Assured wiki 的注释。
Note that the "json path" syntax uses Groovy's GPath notation and is not to be confused with Jayway's JsonPath syntax.
请注意,“json 路径”语法使用 Groovy 的 GPath 表示法,不要与 Jayway 的 JsonPath 语法混淆。
Solution: you can choose one of two ways below:解决方法:您可以选择以下两种方式之一:
<dependency>
<groupId>com.jayway.jsonpath</groupId>
<artifactId>json-path</artifactId>
<version>2.6.0</version>
</dependency>
Response res = given().when().get("/getAllRoles?token=token");
JsonPath.read(res.asString(), "$..ROLEKEY");
List<String> roles = response.jsonPath().getList("Data.roles.ROLEKEY");
System.out.println(roles);
//[1,2,3]
