I am trying to pass a JSONObject to a web service using the following code:
static final String URL_SERVICE="http://888topup.com/ImageProcess.svc/UploadImage";
I have used the following code to upload a JSONObject to the service:
new Thread()
{
public void run()
{
Bitmap bmp=BitmapFactory.decodeFile(pathName);
ByteArrayOutputStream bos=new ByteArrayOutputStream();
bmp.compress(CompressFormat.JPEG, 100, bos);
imgData=bos.toByteArray();
JSONObject obj=ImageWorker.encodeBytes(imgData);
HttpParams params=new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(params, TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(params, TIMEOUT_MILLISEC);
HttpClient client=new DefaultHttpClient(params);
HttpPost post=new HttpPost(URL_SERVICE);
ArrayList<BasicNameValuePair> postParameters=new ArrayList<BasicNameValuePair>();
BasicNameValuePair pair=new BasicNameValuePair("Value",obj.toString());
postParameters.add(pair);
try {
post.setEntity(new UrlEncodedFormEntity(postParameters));
HttpResponse response=client.execute(post);
Log.d(TAG, "Post method has executed");
int status=response.getStatusLine().getStatusCode();
if(status==HttpStatus.SC_OK)
{
Log.d(TAG, "Data passed successfully to web service");
Toast.makeText(getBaseContext(),"Image uploaded successfully",Toast.LENGTH_SHORT).show();
}
} catch (UnsupportedEncodingException e) {
Log.e(TAG, "Error setting post entity",e);
} catch (ClientProtocolException e) {
Log.e(TAG, "Response could not be obtained because of client protocol exception",e);
} catch (IOException e) {
Log.e(TAG, "Response could not be obtained because of IOException");
}
}
}.start();
It says
Response could not be obtained because of IOException
EDIT:
Sometimes,it works and when it does it says response code 400,I have been told that the URL is correct.
I get the image from the gallery using an Intent,I use the following code to obtain a path from the Uri and convert it to JSONObject:
Uri dataUri=data.getData();
Log.d(TAG,"Data uri: "+dataUri);
final String pathName=getRealPathFromUri(dataUri);
public String getRealPathFromUri(Uri uri)
{
String[] projection={MediaStore.Images.Media.DATA};
String selection=null;
String[] selectionArgs=null;
String sortOrder=null;
Cursor c=getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder);
if(c!=null && c.getCount()>0 && c.moveToFirst())
return c.getString(c.getColumnIndex(MediaStore.Images.Media.DATA));
return null;
}
public static JSONObject encodeBytes(byte[] data)
{
JSONObject result=new JSONObject();
try {
String conv=Base64.encodeToString(data, Base64.DEFAULT);
Log.d(TAG, conv);
result.put("title", "IMG_"+System.currentTimeMillis());
result.put("data",conv);
result.put("size",data.length*1024);
} catch (JSONException e) {
Log.e(TAG, "Placing image data in JSONObject failed");
}
return result;
}
