Send JSON object via HttpPost method

by Wayne Wenthin » Wed, 09 Sep 2009 05:39:03 GMT


 A snippet for what I do...
public HttpResponse updateGirl(String url, Pawn girl, int pawnID) {
HttpClient httpclient = new DefaultHttpClient();
HttpPut httpput = new HttpPut(url);

// Execute the request

try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
39);
nameValuePairs.add(new BasicNameValuePair("id", Integer
.toString(pawnID)));
......  Many nameValuePairs later.....


httpput.addHeader("Content-Type",
"application/x-www-form-urlencoded");
httpput.setEntity(new UrlEncodedFormEntity(nameValuePairs,
HTTP.UTF_8));
 HttpResponse response = httpclient.execute(httpput);
return response;

} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
// e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;

}

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

Send JSON object via HttpPost method

by Alok Kulkarni » Wed, 09 Sep 2009 16:44:42 GMT


 ey 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; i<valArray.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) {
/*
* To convert the InputStream to String we use the
BufferedReader.readLine()
* method. We iterate until the BufferedReader return null which
means
* there's no more data to read. Each line will appended to a
StringBuilder
* and returned as String.
*/
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 {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}

return sb.toString();
}

Send JSON object via HttpPost method

 ep 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.
