How To Post With Java HttpClient

Java HttpClient is an HTTP client that supports the most recent HTTP standards and works synchronously and asynchronously.

Today, in this article, we’ll see how to submit some common data formats.

How To Prepare A Post Request

You can prepare a POST request by using the HttpRequest builder easily. We’ll see more details under the further titles.

import java.net.http.HttpRequest;
import java.net.URI;

//...

HttpRequest request = HttpRequest.newBuilder()
 .uri(URI.create("https://example.com"))
 .POST(HttpRequest.BodyPublishers.noBody())
 .build();

How To Prepare A Client Instance

The API allows you to create a configured client instance for a specific purpose through a builder by using newBuilder() method.
For example, you can create a client instance configured with a timeout value for a specific API like the one below.

import java.net.http.HttpClient;

//...

HttpClient client = HttpClient.newBuilder()
                .connectTimeout(PAYMENT_PROCESSOR_CONNECTION_TIMEOUT) 
                .build();

Also, you can create just a new client instance by using newHttpClient() method if no configuration is required.
