[android-beginners] Re: Send JSON object via HttpPost method
Hey Wayne, thanks a lot..
I have also got a solution parallely which i would like to post
URL url = new URL(serverURL);
// open the conncetion
HttpURLConnection connection =
(HttpURLConnection)url.openConnection();
// Let the run-time system (RTS) know that we want input.
connection.setDoInput(true);
// Let the RTS know that we want to do output
connection.setDoOutput(true);
// No caching, we want the real thing
connection.setUseCaches(false);
// set the content type property
connection.setRequestProperty(Content-type,strContenttype);
// set request method
connection.setRequestMethod(POST);
// create the post body to send
String content = credDevPair.toString();
Log.i(Request ... ,content);
DataOutputStream printout = new DataOutputStream (
connection.getOutputStream () );
// send the data
printout.writeBytes(content);
printout.flush();
printout.close();
String output =
convertStreamToString(connection.getInputStream());
Log.i(Response 1... ,output);
// A Simple JSONObject Creation
JSONObject json=new JSONObject(output);
Log.i(Praeda,jsonobject\n+json.toString()+\n/jsonobject);
// A Simple JSONObject Parsing
JSONArray nameArray=json.names();
JSONArray valArray=json.toJSONArray(nameArray);
for(int i=0; ivalArray.length() ;i++)
{
Log.i(Praeda,jsonname+i+\n+nameArray.getString(i)+\n/jsonname+i+\n
+jsonvalue+i+\n+valArray.getString(i)+\n/jsonvalue+i+);
}
//BufferedReader input = new BufferedReader ( new
InputStreamReader(connection.getInputStream()) );
}catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch(Exception ex)
{
}
}
private static String convertStreamToString(InputStream is) {
/*

BufferedReader.readLine()

means

*/
BufferedReader reader = new BufferedReader(new
InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + \n);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {

return sb.toString();

Hope that helps. I struggled with it for a couple of weeks before I found
a site that had a good source.

Yep that is what I vaguely based mine on. I recognize the Praeda line. I
had to modify mine because I was not sending back an array of json objects
but a specific one that I handle based on the ID on the backend with ruby.
