Android httppost authentication error with 401 response code

Question

I have an android application. I have to get data from server through httppost with two parameter. But I always got response code 401 every time. It should be 200.

Here is my log file:

Here is my activity:

public class LoginActivity extends Activity implements OnClickListener {

Button login;
EditText user, pass;
CheckBox ck;
String FILENAME = "check";
String checkenords;

String FILETOKEN = "token";
String tokenStr;

String FILEEmail = "email";
String emailStr;

String responseStr;
String usernamefromuser;
int responsecode;
String passfromuser;
ProgressDialog pDialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.sign_in);
    user = (EditText) findViewById(R.id.editText1);
    pass = (EditText) findViewById(R.id.editText2);
    ck = (CheckBox) findViewById(R.id.checkBox1);
    login = (Button) findViewById(R.id.btnlogin);

    login.setOnClickListener(this);
}


@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    new GetContacts().execute();
}

private class GetContacts extends AsyncTask<Void, Void, Void> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(LoginActivity.this);
        pDialog.setMessage("Wait...");
        pDialog.setIndeterminate(false);
        pDialog.setCancelable(true);
        pDialog.show();
    }

    @Override
    protected Void doInBackground(Void... arg0) {
        // Creating service handler class instance
        usernamefromuser = user.getText().toString();
        passfromuser = pass.getText().toString();

        Log.e("successss", "888888888888");
        Log.e("Username", "User:" + usernamefromuser);
        Log.e("Password", "pass:" + passfromuser);
        HttpClient client = new DefaultHttpClient();
        String url = "http://54.228.199.162/api/auth";
        HttpPost httppost = new HttpPost(url);
        // httppost.setHeader("Content-type", "application/json");
        // httppost.setHeader("Accept", "application/json");

        try {
            List<NameValuePair> namevalpair = new ArrayList<NameValuePair>();
            namevalpair.add(new BasicNameValuePair("pass", passfromuser));
            namevalpair.add(new BasicNameValuePair("email",
                    usernamefromuser));
            UrlEncodedFormEntity entity = new UrlEncodedFormEntity(
                    namevalpair, HTTP.UTF_8);
            httppost.setEntity(entity);
            HttpResponse httpresponse = client.execute(httppost);
            responsecode = httpresponse.getStatusLine().getStatusCode();
            responseStr = EntityUtils.toString(httpresponse.getEntity());
            Log.d("Authentication", "" + responsecode);
            // Log.d("httpresponseeeee", httpresponse.toString());
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();

        ;

        super.onPostExecute(result);
        // Dismiss the progress dialog
        if (responsecode == 200) {
            tokenStr = responseStr;
            emailStr = usernamefromuser;
            try {

                Intent inteGps = new Intent(LoginActivity.this, Gps.class);
                startActivity(inteGps);
                finish();
            } else {

            }
        } else if (responsecode == 401) {

            Toast.makeText(getApplicationContext(), getApplicationContext().getResources().getString(R.string.userwrong),

}

@PratikButani, actually server side is not maintain by me. So there is no way to get code of server side. what kind of authentication on server you are talking about? — Mohammad Rajob, Feb 04 '14 at 04:31
Some Authentication parameter which is passing in Header information, may that you are missing there. — Pratik Butani, Feb 04 '14 at 04:33
@PratikButani, when I click login, in server side there is no value in parameter. How can i solve that? — Mohammad Rajob, Feb 04 '14 at 04:36
You have to contact your server side developer and make sure that you have pass only two parameter `email` and `pass` — Pratik Butani, Feb 04 '14 at 04:43

@MohammadRajob I have updated my answer with code, you have to follow that code, it will surely helpful to you. — Pratik Butani, Feb 04 '14 at 05:24

I suggest you to test your REST api (url) by using cURL or for quick setup use any google crome apps like POSTMAN google chrome extension which helps you test the REST api's in a easiest way!

if your rest api works fine then consider about using that your code, step by step try to trace whether server implementation is wrong or client side implementation wrong or url, parameters are wrong ! also check for <uses-permission android:name="android.permission.INTERNET" /> in your AndroidManifest.xml

enter image description here

public String userSignIn(String user, String pass, String authType)
            throws Exception {



        DefaultHttpClient httpClient = new DefaultHttpClient();
        String url = "https://example/authenticate";


        ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();


        nameValuePairs.add(new BasicNameValuePair("userName", user));
        nameValuePairs.add(new BasicNameValuePair("password", pass));
        // Add more parameters as necessary

        // Create the HTTP request
        HttpParams httpParameters = new BasicHttpParams();

        // Setup timeouts
        HttpConnectionParams.setConnectionTimeout(httpParameters, 15000);
        HttpConnectionParams.setSoTimeout(httpParameters, 15000);

        HttpClient httpclient = new DefaultHttpClient(httpParameters);
        HttpPost httppost = new HttpPost(
                url);
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            HttpResponse response = httpclient.execute(httppost);
    String responseString = EntityUtils.toString(response.getEntity());
            Log.d("resp test", responseString);
    }

Edit:

try with

DefaultHttpClient client = new DefaultHttpClient();
client.getCredentialsProvider().setCredentials(AuthScope.ANY,
            new UsernamePasswordCredentials(username, password));

source: SO

if you tired of using asynch task use volley which minimizes the code of http clients and it's more efficient

Everything is ok there. So what's wrong in my code??????? I got correct result with postman. I used internet permission. — Mohammad Rajob, Feb 04 '14 at 04:51
@MohammadRajob I have posted my answer. see may that will helps you. — Pratik Butani, Feb 04 '14 at 05:07
@MohammadRajob give it try with _https_ first! also ask your server developer, he made SSL with POST method with certificate ? — LOG_TAG, Feb 04 '14 at 06:09
@MohammadRajob May be Your server Developer getting data in JSON format. Have you got solution with my answer? — Pratik Butani, Feb 04 '14 at 09:26
String url = "http://54.228.199.162/api/auth?pass="+passfromuser+"&email="+usernamefromuser; HttpPost httppost = new HttpPost(url); — Mohammad Rajob, Feb 04 '14 at 09:38
I used it and it worked. please click the link and see the url — Mohammad Rajob, Feb 04 '14 at 09:39

Use bellow line in your code.....



HttpParams httpParams = new BasicHttpParams();

HttpClient httpClient = new DefaultHttpClient(httpParams);

HttpPost requestPost = new HttpPost(url);

requestPost.setHeader("*_*****_USERNAME", "admin******");

requestPost.setHeader("*_*****_PASSWORD", "admin@*****");

requestPost.setHeader("Content-Type","application/x-www-form-urlencoded");
//(as per your requirement)

I hope it will Work for u.....

As per your Edited Question, I think you have to use HttpGet to send your authentication on Server.

Here I found example of HttpGet request in Android.

and also Here found StackOverflow Solution.

EDITED:

I have checked your POSTMAN and found that your server accepting JSON Data. You can see in Image:

enter image description here

so now you have to try this code:

   @Override
    protected Void doInBackground(Void... arg0) {

    // Creating service handler class instance
    usernamefromuser = user.getText().toString();
    passfromuser = pass.getText().toString();

    InputStream inputStream = null;
    String result = "";
    try {

        // 1. create HttpClient
        HttpClient httpclient = new DefaultHttpClient();

        // 2. make POST request to the given URL
        HttpPost httpPost = new HttpPost(url);

        String json = "";

        // 3. build jsonObject
        JSONObject jsonObject = new JSONObject();
        jsonObject.accumulate("email", usernamefromuser);
        jsonObject.accumulate("pass", passfromuser);

        // 4. convert JSONObject to JSON to String
        json = jsonObject.toString();

        // ** Alternative way to convert Person object to JSON string usin Jackson Lib 
        // ObjectMapper mapper = new ObjectMapper();
        // json = mapper.writeValueAsString(person); 

        // 5. set json to StringEntity
        StringEntity se = new StringEntity(json);

        // 6. set httpPost Entity
        httpPost.setEntity(se);

        // 7. Set some headers to inform server about the type of the content   
        httpPost.setHeader("Accept", "application/json");
        httpPost.setHeader("Content-type", "application/json");

        // 8. Execute POST request to the given URL
        HttpResponse httpResponse = httpclient.execute(httpPost);

        responsecode = httpresponse.getStatusLine().getStatusCode();
        responseStr = EntityUtils.toString(httpresponse.getEntity());

    } catch (Exception e) {
        Log.d("InputStream", e.getLocalizedMessage());
    }

    return null;
}

Sorry for late found the solution.

Bufferreader not accepted there. rel line under bufferreader. — Mohammad Rajob, Feb 04 '14 at 06:21
Now check, Its just common sense problem that you have to remove your self. — Pratik Butani, Feb 04 '14 at 06:29
