How to Replicate cURL Authentication Functionality in Java?

Java Equivalent to cURL for Authentication Handling

One may encounter a scenario where a JAVA application requires an authentication component interfacing with an in-house widget utilizing HTTPS protocol. Consequently, a port of cURL to JAVA becomes desirable.

The PHP code provided exemplifies the use of cURL to handle the transfer:

$cp = curl_init();
$my_url = "https://" . AUTH_SERVER . "/auth/authenticate.asp?pt1=$uname&pt2=$pass&pt4=full";
curl_setopt($cp, CURLOPT_URL, $my_url);
curl_setopt($cp, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($cp);
curl_close($cp);

To replicate this functionality in JAVA, consider utilizing the HttpsURLConnection class. The following code snippet provides a simplified version, excluding exception handling:

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

This approach effectively handles HTTPS transfers, allowing the application to authenticate with the widget.
