HTTP GET and POST

By default the URLConnection sends an HTTP GET request to the webserver. If you want to send an HTTP POST request instead, call the URLConnection.setDoOutput(true) method, like this:

URL url = new URL("https://vigyancode.blogspot.com/");

URLConnection urlConnection = url.openConnection();

urlConnection.setDoOutput(true);

Once you have set called setDoOutput(true) you can open the URLConnection's OutputStream like this:

OutputStream output = urlConnection.getOutputStream();

Using this OutputStream you can write any data you want in the body of the HTTP request.  

Remember to close the OutputStream when you are done writing data to it.
