4.2.6. HttpsURLConnection

Setting up an HTTPS connection

An HTTPS connection to a URL is set up as follows (Get request):

URL url = new URL("https:/servername/content?param=value")

HttpsURLConnection httpsCon = (HttpsURLConnection)

url.openConnection();

The following properties can be set additionally:

httpsCon.setDoOutput(true);

httpsCon.setUseCaches(false);

// set some cookies

httpsCon.setRequestProperty("Cookie",cookieString);

Caution: The following request is only sent when the HTTP response is requested:

int rc = httpsCon.getResponseCode();

String msg = httpsCon.getResponseMessage();

Reading sent HTML/XML pages

The sent HTML/XML pages are read as follows:

InputStream in = httpsCon.getInputStream();

BufferedReader result = new BufferedReader(new InputStreamReader(in));

Request body for POST request

The following request body is written for a POST request:

DataOutputStream out = new DataOutputStream( httpsCon.getOutputStream());

out.writeBytes("param1=value&param2=value");

Note: The method setRequestMethod() of the connection has no effect on the type of request generated. If the request body is not defined, a GET request is sent, otherwise a POST request.
