RestAssured: Send request headers

‘header’ or ‘headers’ method is used to set request headers.

Example 1

Response response = given().header("Accept", "application/json").when().get("api/v1/employees").thenReturn();

Example 2

Map<String, Object> headers = new HashMap<>();

headers.put("Accept", "application/json");

response = given().headers(headers).when().get("api/v1/employees").thenReturn();

Example 3

Header header = new Header("Accept", "application/json");

Headers headersObj = Headers.headers(header);

response = given().headers(headersObj).when().get("api/v1/employees").thenReturn();

App.java

package com.sample.app;

import static io.restassured.RestAssured.given;

import java.util.Map;

import io.restassured.RestAssured;
import io.restassured.http.Header;
import io.restassured.http.Headers;
import io.restassured.response.Response;

public class App {
    private static int requestCount = 0;

    private static void printResponse(Response response) {
        System.out.println("For the " + (++requestCount) + " request");
        String respStr = response.getBody().asString();
        System.out.println(respStr + "\n");
    }

    public static void main(String args[]) {
        RestAssured.baseURI = "http://localhost:8080";

        Response response = given().header("Accept", "application/json").when().get("api/v1/employees").thenReturn();
        printResponse(response);

        Map<String, Object> headers = new HashMap<>();
        headers.put("Accept", "application/json");
        response = given().headers(headers).when().get("api/v1/employees").thenReturn();
        printResponse(response);

        Header header = new Header("Accept", "application/json");
        Headers headersObj = Headers.headers(header);
        response = given().headers(headersObj).when().get("api/v1/employees").thenReturn();
        printResponse(response);
    }
}
