Question

I want to use HTTP GET and POST commands to retrieve URLs from a website and parse the HTML. How do I do this?

Answer 1

You can use HttpURLConnection in combination with URL.

URL url = new URL('http://example.com'); HttpURLConnection connection = (HttpURLConnection)url.openConnection(); connection.setRequestMethod('GET'); connection.connect();  InputStream stream = connection.getInputStream(); // read the contents using an InputStreamReader
