POAuthorization fails in HttpURLConnection in File Download Android
text
Body
copied!<p>I want to download a zip file from the server in Android and for that I am using the below code. It also requires authorization so for that I am passing the username and password in the request of the URL connection. But I am always getting <strong>401-Response code(UNAUTHORIZED)</strong>.</p> <p>Code :-</p> <pre><code>protected String doInBackground(final String... params) { int count; try { if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) { /*Authenticator.setDefault(new Authenticator(){ protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(Constants.USERNAME,Constants.PASSWORD.toCharArray()); }});*/ Log.i(TAG, "URL == " + params[0]); final URL url = new URL(params[0]); final HttpURLConnection connection = (HttpURLConnection) url.openConnection(); final String auth = new String(Constants.USERNAME + ":" + Constants.PASSWORD); connection.setRequestProperty("Authorization", "Basic " + Base64.encodeToString(auth.getBytes(), Base64.URL_SAFE)); //connection.addRequestProperty("Authorization", "Basic " + Base64.encodeToString(auth.getBytes(), Base64.DEFAULT)); connection.setUseCaches(false); connection.setConnectTimeout(5000); connection.setDoOutput(true); connection.connect(); Log.i(TAG, "Response == " + connection.getResponseMessage()); Log.i(TAG, "Response Code == " + connection.getResponseCode()); // download the file final InputStream input = new BufferedInputStream(connection.getInputStream()); // Path to the just created empty db // this will be useful so that you can show a tipical 0-100% progress bar lenghtOfFile = connection.getContentLength(); lengthOfFileInMB = lenghtOfFile / 1048576; Log.i(TAG, "File Size in MB = " + lengthOfFileInMB); outFileName = Environment.getExternalStorageDirectory() + File.separator + ZIP_NAME; final File file = new File(outFileName); if (!file.exists()) { file.createNewFile(); } // Output stream final BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(new FileOutputStream(file)); final byte data[] = new byte[lenghtOfFile]; long total = 0; while ((count = input.read(data)) != -1) { total += count; publishProgress("" + total); bufferedOutputStream.write(data, 0, count); } bufferedOutputStream.flush(); bufferedOutputStream.close(); input.close(); } else { Toast.makeText(DashboardActivity.this, "MEDIA IS NOT MOUNTED.", Toast.LENGTH_LONG).show(); } } catch (final MalformedURLException e) { flag = false; Log.e(TAG, e.getMessage(), e); } catch (final FileNotFoundException e) { flag = false; Log.e(TAG, e.getMessage(), e); } catch (final IOException e) { flag = false; Log.e(TAG, e.getMessage(), e); } catch (final Exception e) { Log.e(TAG, e.getMessage(), e); } return null; } </code></pre> <p><strong>I am having the web service in the same server and for getting JSON/XML response I used the DefaultHttpClient. That is working perfectly fine and I am getting the response code OK as well. I don't know why it is not authorizing at the time of URLConnection.</strong></p> <p>Here is the code of it.</p> <pre><code>String line = null; try { final URL urlObj = new URL(url); final HttpHost host = new HttpHost(urlObj.getHost(), urlObj.getPort(), urlObj.getProtocol()); final HttpParams httpParameters = new BasicHttpParams(); // Set the timeout in milliseconds until a connection is established. HttpConnectionParams.setConnectionTimeout(httpParameters, Constants.CONNECTION_TIME_OUT); // Set the default socket timeout (SO_TIMEOUT) // in milliseconds which is the timeout for waiting for data. HttpConnectionParams.setSoTimeout(httpParameters, Constants.CONNECTION_TIME_OUT); final DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters); final AuthScope scope = new AuthScope(urlObj.getHost(), urlObj.getPort()); final UsernamePasswordCredentials creds = new UsernamePasswordCredentials(Constants.USERNAME, Constants.PASSWORD); final CredentialsProvider credentialProvider = new BasicCredentialsProvider(); credentialProvider.setCredentials(scope, creds); final HttpContext credContext = new BasicHttpContext(); credContext.setAttribute(ClientContext.CREDS_PROVIDER, credentialProvider); final HttpGet job = new HttpGet(url); job.addHeader("USER-AGENT", userAgentString); final HttpResponse httpResponse = httpClient.execute(host,job,credContext); final HttpEntity httpEntity = httpResponse.getEntity(); try { line = EntityUtils.toString(httpEntity); } catch (final ParseException e) { line = "Error"; Log.e("Parse Error", e.getMessage().toString()); } catch (final IOException e) { line = "Error"; Log.e("IOException Error", e.getMessage().toString()); } final StatusLine status = httpResponse.getStatusLine(); Log.d("Authentication Status = ", status.toString()); } catch (final ClientProtocolException e1) { line = "Error"; Log.e("ClientPrtocol Error", e1.getMessage().toString()); } catch (final ConnectTimeoutException e1) { line = "ConnectionTimeOut"; Log.e("Connection Error", e1.getMessage().toString()); } catch (final IOException e1) { Log.e("IO Error", e1.getMessage().toString()); line = "Error"; } </code></pre> <p>I also tried to add the following code in URLConnection for authentication but that also not worked for me.</p> <pre><code>Authenticator.setDefault(new Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(loginNameString, passwordString.toCharArray()); } }); </code></pre> <p><strong>Questions:-</strong></p> <p><strong>1) Is it problem at server side or at android side?</strong></p> <p><strong>2) Can I download the file using the defaulthttpclient code that I have? If yes any clue how to download it, because I think i can only get content from that way not the whole file.</strong></p>
