如何使用 RestAssured.JsonPath 从 JSON 获取特定属性的值

Question

I'm trying to hit an API thru RestAssured + Java code and able to get some response as you can see in this post. But I need to get the value of particular node / attribute ie errorParams which is present in the JSON and print in the Java Console.

{
   "customerId":null,
   "errorDetails":[
      [
         {
            "errorCode":"ABC_2021",
            "errorParams":"Input Customer Id"
         }
      ]
   ]
}

I tried like this and not working.

JsonPath jsp = new JsonPath(response.getBody().asString());

System.out.println(jsp.getString("errorDetails.errorParams"));

System.out.println(jsp.getString("$['errorDetails']['errorParams']"));

Any suggestions or working script would be helpful for me.

Thanks,

Answer 1

That one works just fine:

System.out.println(jsp.getString("errorDetails.errorParams"));

So I assumed you retrieving your JsonPath in the wrong way, try:

JsonPath jsp = response.jsonPath();

or

JsonPath jsp = new JsonPath(response.asString());

Answer 2

you can use the following snippet it works for me

System.out.println(response.jsonPath().getString("errorDetails.errorParams"));
