Java 11: New HTTP client send POST requests with x-www-form-urlencoded parameters

I’m trying to send a POST request using the new http client api. Is there a built in way to send parameters formatted as x-www-form-urlencoded ?

My current code:

HttpRequest request = HttpRequest.newBuilder()
        .header("Content-Type", "application/x-www-form-urlencoded")
        .POST(BodyPublishers.ofString("a=get_account&account=" + URLEncoder.encode(account, "UTF-8")))

What I’m looking is for a better way to pass the parameters. Something like this:

Params p=new Params();

Do I need to build myself this functionality or is something already built in?

I’m using Java 12.



I think the following is the best way to achieve this using Java 11:

Map<String, String> parameters = new HashMap<>();
parameters.put("a", "get_account");
parameters.put("account", account);

String form = parameters.entrySet()
    .map(e -> e.getKey() + "=" + URLEncoder.encode(e.getValue(), StandardCharsets.UTF_8))

HttpClient client = HttpClient.newHttpClient();

HttpRequest request = HttpRequest.newBuilder()
    .headers("Content-Type", "application/x-www-form-urlencoded")

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

System.out.println(response.statusCode() + " " + response.body().toString());
