HttpURLConnection.setRequestMethod()

Answer 2

String rawData = "id=10";
String type = "application/x-www-form-urlencoded";
String encodedData = encode( rawData ); 
URL u = new URL("http://www.example.com/page.php");
URLConnection c = u.openConnection();
c.setDoOutput(true);
conn = (HttpURLConnection)c;
conn.setRequestMethod( HttpConnection.POST );
conn.setRequestProperty( "Content-Type", type );
conn.setRequestProperty( "Content-Length", encodedData.length() );
OutputStream os = conn.openOutputStream();
os.write( encodedData.getBytes() );

Answer 3

Hi,

I recommend to use Apache HttpClient. its faster and easier to implement.

PostMethod post = new PostMethod("http://jakarata.apache.org/");
        NameValuePair[] data = {
          new NameValuePair("user", "joe"),
          new NameValuePair("password", "bloggs")
        };
        post.setRequestBody(data);
        // execute method and handle any error responses.
        ...
        InputStream in = post.getResponseBodyAsStream();
        // handle response.
