Trying to get OutputStream for http connection

Postby ohechkay » Wed Dec 02, 2009 6:56 am

I'm trying to http connect to a server and write a request parameters with a DataOutputStream but I haven't used any API besides org.apache.http libraries which use entities instead of direct streams. I've tried these entities but it hasn't been working. It connects fine but I receive nothing back from the server, presumably because the server didn't read the parameters correctly.

My client code looks like this but doesn't work.

What libraries does Android support that would establish the http connection and let me directly write to the output stream?

Thanks for the reply.

I just tried this:

Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1.  
  2.                 String uri = URL;
  3.  
  4.                 URL url = new URL(uri + URLEncoder.encode(URL_PARAM));
  5.  
  6.                 Log.d("Connection", "Starting");
  7.  
  8.                 HttpURLConnection con = (HttpURLConnection)url.openConnection();
  9.  
  10.  
  11.  
  12.             con.setDoInput( true );
  13.  
  14.             con.setDoOutput( true );
  15.  
  16.             con.connect();
  17.  
  18.  
  19.  
  20.                 OutputStream os = con.getOutputStream();
  21.  
  22.                 DataOutputStream daos = new DataOutputStream(os);
  23.  
  24.  
  25.  
  26.                 daos.writeUTF(U1);
  27.  
  28.                 daos.writeUTF(P1);
  29.  
  30.                 daos.writeUTF("param");
  31.  
  32.                 daos.writeUTF("en");
  33.  
  34.                 daos.writeByte(6);
  35.  
  36.                 daos.writeInt(1);
  37.  
  38.                 daos.flush();
  39.  
  40.                 daos.close();
  41.  
  42.  
Parsed in 0.011 seconds, using GeSHi 1.0.8.4

But this times out at the three line setting con fields and connecting. If the lines are commented out, I get a ProtocolException: does not support output.

Help?
