How do we pass parameters when doing HTTP Post?

Question

I am working on an app where we have to pass specific web api parameters to a web app using HTTP POST. eg: apimethod name parameter1 value parameter2 value So do I use a string or URLEncodedPostData to send that data? It would be good if u help me with a code eg. I am using something like this but it doesnt post the data to the server. Though the response code is ok/200 and I also get get a parsed html response when i read the httpresponse input stream. But the code doesnt post anything. So unable to get the expected response.

             _postData.append("method", "session.getToken");
       _postData.append( "developerKey", "value");
       _postData.append( "clientID", "value");

      _httpConnection = (HttpConnection) Connector.open(URL, Connector.READ_WRITE);
      String encodedData = _postData.toString();
      _httpConnection.setRequestMethod(HttpConnection.POST);
      _httpConnection.setRequestProperty("User-Agent", "BlackBerry/3.2.1");
      _httpConnection.setRequestProperty("Content-Language", "en-US");
      _httpConnection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
      _httpConnection.setRequestProperty("Content-Length",(new Integer(encodedData.length())).toString());
      os = _httpConnection.openOutputStream();
      os.write(requeststring.getBytes());`

Answer 1

POSTed parameters are usually sent in the response BODY, which means URL-encoding them is inappropriate. Quote from the HTTP/1.1 protocol:

  Note: The "multipart/form-data" type has been specifically defined
  for carrying form data suitable for processing via the POST
  request method, as described in RFC 1867 [15].

Answer 2

The post method allows you to use pretty arbitrary message bodies — so it is whatever format the server wants.

Answer 3

The code you posted above looks correct - although you'll want to do a few more things (maybe you did this already but didn't include it in your code):

1. Close the outputstream once you've written all the bytes to it
2. Call getResponseCode() on the connection so that it actually sends the request

Answer 4

I know this thread is probably dead, however as i'm having a similiar issue, thought i'd comment

surely requeststring is meant to be encodedData?
