//Exemple :
package com.zetcode;

import com.fasterxml.jackson.databind.ObjectMapper;

import java.io.IOException;
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.util.HashMap;

public class HttpClientPost {

    public static void main(String[] args) throws IOException, InterruptedException {

        var values = new HashMap<String, String>() {{
            put("name", "John Doe");
            put ("occupation", "gardener");
        }};

        var objectMapper = new ObjectMapper();
        String requestBody = objectMapper
                .writeValueAsString(values);

        HttpClient client = HttpClient.newHttpClient();
        HttpRequest request = HttpRequest.newBuilder()
                .uri(URI.create("https://httpbin.org/post"))
                .POST(HttpRequest.BodyPublishers.ofString(requestBody))
                .build();

        HttpResponse<String> response = client.send(request,
                HttpResponse.BodyHandlers.ofString());

        System.out.println(response.body());
