Send Post request with Bearer token and Nested input value using Rest-Assured.

I have this API post request which creates a record.

It’s payload is as per below.

"sysId": "666666",
"plannedStart" : "02-24-2022 17:00:00",
"plannedEnd" : "02-27-2022 17:10:00",
"changeDetails" : {
 "requirement" : "https:"
 }
}

The the response is like below.

{
    "result": {
        "change": {
            "sys_id": "66",
            "number": "777"
        },
        "status": "OK",
        "message": "Change Request Created Successfully"
    }
}

How to achieve this in Rest Assured with Java?

Code solution is as per below.

import io.restassured.RestAssured;
import io.restassured.path.json.JsonPath;
import io.restassured.response.Response;
import io.restassured.specification.RequestSpecification;
import org.json.JSONObject;
import org.testng.annotations.Test;

public class PostRequest {
    @Test
    public void sendPostRequestWithBearerTokenAndNestedInput(){

        RequestSpecification request = RestAssured.given();
        request.header("Content-Type", "application/json");
        // Mention the keys and values which wish to pass as haeders.
        request.header("key", "value");
        // Give the username and password.
        request.auth().basic("username", "password");
        //  Give the bearer token.
        request.header("Authorization", "Basic 66666==");

        // Create Json Object to store attributes
        JSONObject jsonPayloadBody = new JSONObject();

        // Now let's see how to add a nested parameter. Define a object as changeDetails
        JSONObject changeDetailsObject = new JSONObject();
        // For inside of that , add requirement, key and value.
        changeDetailsObject.put("requirement", "https");
        // Attach those attributes to Body after convert them in to JsonString
        request.body(jsonPayloadBody.toString());
        // Post the request with URL
        Response response = request.post("https://URI");
        int actual_Status_Code = response.getStatusCode();
        System.out.println("actualStatuscode"+actual_Status_Code);
        // Assert.assertEquals(actual_Status_Code, 200, "ID does not matches in API response.");
        JsonPath jsonPathEvaluator = response.jsonPath();
        //Extract the ticket number.
        System.out.println("Response is "+response.asString());
        // Here Number is inside of result.change. So using result.change.number we can extract the value/
        String ticketNumber = jsonPathEvaluator.get("result.change.number");
    }
}
