Maybe the problem is the BufferedInputStream. I wrote this code (a long time ago) if you want to try it.
Give an input stream to the fonction and let it work.
import java.io.InputStream;
import java.util.Scanner;
/**
* Created by badetitou.
*/
public class ReadIt {
public static String ReadIt(InputStream is){
return new Scanner(is,"UTF-8").useDelimiter("").next();
}

Android - Configuring Retrofit/Apache HttpClient for Digest Auth

I am working on an Android project and trying to get Digest Authentication to work with Retrofit. I'm kind of amazed Retrofit doesn't natively support it (or more accurately, that OkHttp doesn't support it), but no point complaining I suppose.
I cruised through quite a few threads here and it appears the right solution is to integrate the Apache HttpClient (which natively supports Digest Auth) with Retrofit. This requires wrapped the HttpClient with a retrofit.client.Client implementation. The retrofit incoming values have to be parsed and built into a new HttpClient response which is then sent back to Retrofit to be processed normally. Credit to Jason Tu and his example at: https://gist.github.com/nucleartide/24628083decb65a4562c
Issue is, it isn't working. I'm getting a 401 Unauthorized every time and it's not clear to me why. Here's my Client impl:
public class AuthClientRedirector implements Client {
private final CloseableHttpClient delegate;
public AuthClientRedirector(String user, String pass, String hostname, String scope) {
Credentials credentials = new UsernamePasswordCredentials(user, pass);
AuthScope authScope = new AuthScope(hostname, 443, scope);
CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
credentialsProvider.setCredentials(authScope, credentials);
delegate = HttpClientBuilder.create()
.setDefaultCredentialsProvider(credentialsProvider)
.build();
}
#Override
public Response execute(Request request) {
//
// We're getting a Retrofit request, but we need to execute an Apache
// HttpUriRequest instead. Use the info in the Retrofit request to create
// an Apache HttpUriRequest.
//
String method = request.getMethod();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
if (request.getBody() != null) {
try {
request.getBody().writeTo(bos);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
String body = new String(bos.toByteArray());
HttpUriRequest wrappedRequest;
switch (method) {
case "GET":
wrappedRequest = new HttpGet(request.getUrl());
break;
case "POST":
wrappedRequest = new HttpPost(request.getUrl());
wrappedRequest.addHeader("Content-Type", "application/xml");
try {
((HttpPost) wrappedRequest).setEntity(new StringEntity(body));
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
break;
case "PUT":
wrappedRequest = new HttpPut(request.getUrl());
wrappedRequest.addHeader("Content-Type", "application/xml");
try {
((HttpPut) wrappedRequest).setEntity(new StringEntity(body));
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
break;
case "DELETE":
wrappedRequest = new HttpDelete(request.getUrl());
break;
default:
throw new AssertionError("HTTP operation not supported.");
}
CloseableHttpResponse apacheResponse = null;
try {
apacheResponse = delegate.execute(wrappedRequest);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if(apacheResponse!=null){
// Perform the HTTP request.
CloseableHttpResponse response = null;
try {
response = delegate.execute(wrappedRequest);
// Return a Retrofit response.
List<Header> retrofitHeaders = toRetrofitHeaders(
response.getAllHeaders());
TypedByteArray responseBody;
if (response.getEntity() != null) {
responseBody = new TypedByteArray("",
toByteArray(response.getEntity()));
} else {
responseBody = new TypedByteArray("",
new byte[0]);
}
System.out.println("this is the response");
System.out.println(new String(responseBody.getBytes()));
return new retrofit.client.Response(request.getUrl(),
response.getStatusLine().getStatusCode(),
response.getStatusLine().getReasonPhrase(), retrofitHeaders,
responseBody);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
if (response != null) {
try {
response.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
//failed to return a new retrofit Client
return null;
}
private List<Header> toRetrofitHeaders(org.apache.http.Header[] headers) {
List<Header> retrofitHeaders = new ArrayList<>();
for (org.apache.http.Header header : headers) {
retrofitHeaders.add(new Header(header.getName(), header.getValue()));
}
return retrofitHeaders;
}
private byte[] toByteArray(HttpEntity entity) throws IOException {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
entity.writeTo(bos);
return bos.toByteArray();
}
}
My retrofit configuration looks like this:
public final RestAdapter configureService(){
AuthClientRedirector digestAuthMgr = new AuthClientRedirector(username,password,"myhostname","public");
RestAdapter.Builder builder = new RestAdapter.Builder()
.setEndpoint("http://myhostname:8003/endpoint")
.setLogLevel(RestAdapter.LogLevel.FULL)
.setClient(digestAuthMgr);
return builder.build();
}
I am stumped why I'm consistently getting 401s back from the server. I've walked through the response building process and it looks clean to me, so I'm thinking I'm missing something fundamental. The credentials are good and I have verified them outside the app. Anyone walked this walk before?

You are using port number 443 for authentication.
AuthScope authScope = new AuthScope(hostname, 443, scope);
But, it seems that your real port number is 8003.
RestAdapter.Builder builder = new RestAdapter.Builder()
.setEndpoint("http://myhostname:8003/endpoint")
So, how about use port number 8003 for authentication like below?
AuthScope authScope = new AuthScope(hostname, 8003, scope);

Android Http to Https and SSL crt

I am working on https post request.
I did successfully http post request but i don't know how to change it with https SSL crt.
How can I add SSL crt in project and how to convert http to https.
I tried many examples but i didn't get it.
My http post request code is.. saVersion is my lib
public class ServerCommunication implements Runnable, IServerCommunication {
private static final String TAG = ServerCommunication.class.getSimpleName();
private String url;
private String userAgent;
private byte[] data;

{
System.loadLibrary("saNative");
}
private static void receiveBytestream(byte[] stream)
{
saVersion.getInstance().onSecurePacketReceived(stream);
}
/**

*/
public ServerCommunication()
{
Log.d(TAG, "Note this class is deprecated");
}
private ServerCommunication(String _url, String _userAgent, byte[] _data)
{
url = _url;
userAgent = _userAgent;
data = _data;
}
public void run()
{
DefaultHttpClient httpclient = new DefaultHttpClient();
if(url.equals(""))
{
Log.e(TAG, "URL is an empty string... aborting sending procedure");
return;
}
// make URL
HttpPost httpost = new HttpPost(url);
StringEntity se;
try {
se = new StringEntity(new String(data) + "\r\n");
httpost.setEntity(se);
httpost.setHeader("Accept", "application/json");
httpost.setHeader("Content-Type", "application/json");
// Get User Agent String
httpost.setHeader("User-Agent", userAgent); // set string
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
HttpResponse response = httpclient.execute(httpost);
InputStreamReader sr = new InputStreamReader(response.getEntity().getContent());
byte[] respContent = IOUtils.toByteArray(sr);
receiveBytestream(respContent);
}
catch (ClientProtocolException e)
{
Log.e(TAG, "AS-Connection error: Probably Internet-Permission is not set in your manifest?");
e.printStackTrace();
}
catch (IOException e)
{
Log.e(TAG, "AS-Connection error: Probably Internet-Permission is not set in your manifest?");
e.printStackTrace();
}
finally
{
}
}
#Override
public void sendSecurePacket(String _url, byte[] _data, String userAgent) {
ServerCommunication sc = new ServerCommunication(_url, userAgent, _data);
Thread t = new Thread(sc);
t.start();
}
}

I faced this same issue before some days, I have published into my blog. Refer it. Hope it helps you regarding same.

Android - Post status update with media Twitter & Tumblr

I am trying to allow Android users to post images to Twitter/Tumblr using my app. I am able to authenticate and retrieve user and account info, but I am having trouble with the actual image upload. (Basically I'm ok with all of the HTTP GET api calls, but not the HTTP POST).
I am receiving the following errors (Twitter/Tumblr respectively):
"response":{"errors":[{"message":"Error creating status","code":189}]}
"response":{"errors":["Error uploading photo."]},"meta":{"msg":"Bad Request","status":400}
Does anyone know what this means? I don't believe it's an authentication error, because I am able to get user info, etc... It looks to me like the problem is with the parameters, presumably media.
I have tried a number of options, including using the image file/data/url, using HttpParams/MultipartEntity, and using "media"/"media[]" but haven't had much success. Below is the current code that I am using. Is there something wrong with my format? Is there something else Twitter/Tumblr is looking for? If anyone has any ideas, suggestions, or improvements, they would be much appreciated. Thanks!

Android HttpGet is requesting indexAction

my HttpGet request is calling my indexAction, instead of getAction. What's going on?
Here are my codes:
public function getAction() {
$id = $this->_getParam('id');
if(!$id)
{
$this->getResponse()
->setHttpResponseCode(400)
->setBody("no id");
return;
}
try
{
$q = Doctrine_Query::create()
->from('Milotin_Model_Locations l')
->where ('l.id=?', $id);
$result = $q->fetchArray();
if(count($result) == 1)
{
$this->getResponse()
->setHttpResponseCode(200)
->setBody(json_encode($result));
}
}
catch(Exception $e)
{
$this->getResponse()
->setHttpResponseCode(500)
->setBody($e->getMessage());
}
}
public function indexAction() {
}
And here is my code in Android:
private static void getLoc()
{
final HttpResponse response;
final HttpGet getRequest = new HttpGet(LOCATION_URI + "?geolat=" + geoLat + "&geolong=" + geoLong);
try {
response = mHttpClient.execute(getRequest);
if(response.getStatusLine().getStatusCode() == 200)
{
//do something
}
} catch (ClientProtocolException e) {
Log.e(TAG, e.getMessage());
e.printStackTrace();
} catch (IOException e) {
Log.e(TAG, e.getMessage());
e.printStackTrace();
} catch (JSONException e) {
Log.e(TAG, e.getMessage());
e.printStackTrace();
}
}
My HttpPost is working correctly (it calls postAction), Any explanation?
Thanks.

I found the answer. It's actually the behavior of Zend Framework. If the 'id' element is not found in the GET request, it will redirect to indexAction, instead of getAction.
Example:
'GET localhost/student' will redirected to indexAction, while
'GET localhost/student/23' will redirected to getAction. (23 is the id)
Found it in Zend Framework: A beginner's guide, by Vikram Vaswani.
