How to delete specific parameter using their id in Rest Assured? - json

Question

Below is the json response
{
"details": [
{
"UserName": "john",
"id": "abc_123",
"LastName": "smith"
}
]
}
I need to delete only the UserName parameter :
request.delete("http://localhost:8080/details/id/UserName");
The above code does not seem to work and my expected is as below
{
"details": [
{
"id": "abc_123",
"LastName": "smith"
}
]
}

Please check for the Minimal, Complete, and Verifiable example before posting a question on SO, There are people to help but we would need to know what you've tried beforehand.
To answer your question, You should use a PUT and not a DELETE cause you are trying to update the payload. DELETE as the name suggests will delete the complete resource
Check this link for more detail
PUT calls are resource specific so you will have to mention which entity should be affected.
I have come up with a sample code based on the details you've provided
Used HashMap here but you could also post the body as such or use POJO or JSONObject
{
Map < String, Object > map = new HashMap < > ();
map.put("details", Arrays.asList(new HashMap < String, Object > () {
{
put("id", "abc_123");
put("LastName", "smith");
}
}));
RequestSpecification req = RestAssured.given();
req.header("Content-Type", "application/json");
req.body(map).when();
Response resp = req.put("http://localhost:8080/details/id/abc_123");
String body = resp.asString();
System.out.println("Response is : " + body);
}
