How can I send POST data through url.openStream()?
i'm looking for tutorial or quick example, how i can send POST data throw openStream.
My code is:
URL url = new URL("http://localhost:8080/test");
InputStream response = url.openStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(response, "UTF-8"));
Could you help me ?
URL url = new URL(urlSpec);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod(method);
connection.setDoOutput(true);
connection.setDoInput(true);
// important: get output stream before input stream
OutputStream out = connection.getOutputStream();
out.write(content);
out.close();
// now you can get input stream and read.
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line = null;
while ((line = reader.readLine()) != null) {
writer.println(line);
}
Use Apache HTTP Compoennts http://hc.apache.org/httpcomponents-client-ga/
tutorial: http://hc.apache.org/httpcomponents-client-ga/tutorial/html/fundamentals.html
Look for HttpPost - there are some examples of sending dynamic data, text, files and form data.
Apache HTTP Components in particular, the Client would be the best way to go. It absracts a lot of that nasty coding you would normally have to do by hand
