Is There a Java Equivalent to cURL for HTTPS Authentication?

JAVA Library Equivalent to cURL

Question:

In an open-source Java application, a developer seeks to implement an authentication component leveraging an in-house widget employing HTTPS. The question arises: is there a Java equivalent to cURL or a suitable base package that can facilitate this task?

Answer:

The Java Development Kit (JDK) offers an alternative to cURL through the HttpURLConnection class. Here's a simplified example that demonstrates how to use it:

<code class="java">HttpURLConnection con = (HttpURLConnection) new URL("https://www.example.com").openConnection();
con.setRequestMethod("POST");
con.getOutputStream().write("LOGIN".getBytes("UTF-8"));
con.getInputStream();</code>

This code establishes a connection to a remote URL using the HTTPS protocol, sets the request method to POST, sends data to the server, and retrieves the server's response. Exception handling has been omitted for brevity.
