I'm trying to send username and password as basic authorization with JsonObjectRequest. I've tried to Override getHeaders() method but it didn't work. Here is my code:
public class NewPostRequest extends JsonObjectRequest {
public NewPostRequest(JSONObject requestBody) {
super(Method.POST, APIConstants.CREATE_POST_URL, requestBody, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
long postId = response.getLong("id");
NewPostResponse newPostResponse = new NewPostResponse(postId);
EventBus.getDefault().post(newPostResponse);
} catch (JSONException e) {
e.printStackTrace();
EventBus.getDefault().post(new NewPostResponse(-1));
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
EventBus.getDefault().post(new NewPostResponse(-1));
}
});
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
String credentials = "****:***********************";
String auth = "Basic "
+ Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);
headers.put("Content-Type", "application/json; charset=utf-8");
headers.put("Authorization", auth);
return headers;
}
#Override
protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
JSONObject jsonObject = null;
try {
String data = new String(response.data,
HttpHeaderParser.parseCharset(response.headers));
jsonObject = new JSONObject(data);
} catch (UnsupportedEncodingException | JSONException e) {
e.printStackTrace();
}
return Response.success(jsonObject, HttpHeaderParser.parseCacheHeaders(response));
}
}
Error when i used Base64.NO_WRAP:
com.android.volley.AuthFailureError
And when i used Base64.DEFAULT:
java.lang.IllegalArgumentException: Unexpected char 0x0a at 46 in header value: Basic *************************
Note: This web service is working on Google Postman tool.
Check my answer its working fine for me.

I am trying to make Post request from Android App that takes username and password in request body with content-type application/json in headers.
I tried changing content-type and how i send username passoword in body, but still no luck
public class MainActivity extends AppCompatActivity {
private Button Login;
private EditText loginEmail, loginPassword;
String URL = "https://localhost:8080/api/v1/auth";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

Login = (Button)findViewById(R.id.btnLogin);
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("username", loginEmail.getText().toString());
} catch (JSONException e) {
e.printStackTrace();
}
try {
jsonObject.put("password", loginPassword.getText().toString());
} catch (JSONException e) {
e.printStackTrace();
}
final String requestBody = jsonObject.toString();
Login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
StringRequest request = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {

Post Request from Postman works perfectly fine but it throws Error 400 with Volley.
Below is the error I get in console
"errorSummary":"Bad request. Accept and/or Content-Type headers likely do not match supported values."
Try using a custom request and extending Request<JSONObject>:
CustomRequest class:
public class CustomRequest extends Request<JSONObject> {
private final Map<String, String> mHeaders;
private final JSONObject mBody;
private final Response.Listener<JSONObject> mResponseListener;
public CustomRequest(int method, String url, Map<String, String> headers, JSONObject body, Response.Listener<JSONObject> responseListener, Response.ErrorListener errorListener) {
super(method, url, errorListener);
this.mHeaders = headers;
this.mBody = body;
this.mResponseListener = responseListener;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
return mHeaders != null ? mHeaders : super.getHeaders();
}
#Override
public String getBodyContentType() {
return "application/json; charset=UTF-8";
}
#Override
public byte[] getBody() throws AuthFailureError {
return mBody != null ? mBody.toString().getBytes(Charset.forName("UTF-8")) : super.getBody();
}
#Override
protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
try {
String jsonString = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
return Response.success(new JSONObject(jsonString), HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException | JSONException e) {
return Response.error(new ParseError(e));
}
}
#Override
protected void deliverResponse(JSONObject response) {
mResponseListener.onResponse(response);
}
}
Usage:
String url = "https://localhost:8080/api/v1/auth";
Map<String, String> headers = new HashMap<>();
headers.put("Content-Type", "application/json");
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("username", loginEmail.getText().toString());
jsonObject.put("password", loginPassword.getText().toString());
} catch (JSONException e) {
e.printStackTrace();
}
CustomRequest customRequest = new CustomRequest(Request.Method.POST, url, headers, jsonObject, response -> {
// put your reponse listener code here
}, error -> {
// put your error listener code here
});
RequestQueue queue = Volley.newRequestQueue(context);
queue.add(customRequest);
I am making a new android application and i am a beginner. starting with my Login Activity, i am trying to use POST for sending parameters. but when i debug i found no parameters being passed. Tried almost many answers in stack overflow, none solved my issue. Can anyone help
private void jsonRequestLogin() {
try {
RequestQueue requestQueue = Volley.newRequestQueue(this);
String URL = Constants.LOGIN_URL;
JSONObject jsonBody = new JSONObject();
jsonBody.put("Username", uName.getText().toString().trim());
jsonBody.put("Password", paswd.getText().toString().trim());
final String requestBody = jsonBody.toString();
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("VOLLEY", response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("VOLLEY", error.toString());
}
}) {
#Override
public String getBodyContentType() {
return "application/json; charset=utf-8";
}
#Override
public byte[] getBody() throws AuthFailureError {
try {
return requestBody == null ? null : requestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", requestBody, "utf-8");
return null;
}
}
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String responseString = "";
if (response != null) {
responseString = String.valueOf(response.statusCode);
// can get more details such as response.headers
}
return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
}
};
requestQueue.add(stringRequest);
} catch (JSONException e) {
e.printStackTrace();
}
}
Use getParams() method for requesting the parameters
private void check() {
StringRequest stringRequest = new StringRequest(Request.Method.POST,url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
//Log.d(TAG, "onResponse:" + response);
try {
JSONArray responseArray = new JSONArray(response);
JSONObject jsonObject = responseArray.getJSONObject(0);
//Log.d(TAG, "onResponse: jsonArray " + responseArray);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
//Log.d(TAG, "onErrorResponse: " + error);
Toast.makeText(SplashScreenActivity.this, "Some error occurred try after sometimes", Toast.LENGTH_SHORT).show();
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> params = new HashMap<String, String>();
params.put("param1",param1);
params.put("param2", param2;
//Log.d(TAG, "getParams: " + params);
return params;
}
};
addToRequestQueue(stringRequest, "");
}
Try to override the headers method and put content type init.
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
I think you should use retrofit
Retrofit
Retrofit 2
I am trying to learn Volley library for posting data into webservices. I need to implement user registration form, following is the image of postman with parameters and header...
now problem is, i am getting below error
com.android.volley.ServerError
this is my code for volley post method.
public void postNewComment(){
try {
RequestQueue requestQueue = Volley.newRequestQueue(this);
String URL = "http://myurl/api/users";
JSONObject jsonBody = new JSONObject();
jsonBody.put("email", "test1#gmail.com");
jsonBody.put("user_type", "C");
jsonBody.put("company_id", "0");
jsonBody.put("status", "A");
jsonBody.put("password", "123456");

please suggest where am i getting wrong. URL is working correct with postman, also as you can see i need to set 2 headers. I also tried this Url post method with AsyncTask and its working good. Now i need to implement this using volley library. kindly suggest. thank you.
this is my logcat error:
E/Volley: [81910] BasicNetwork.performRequest: Unexpected response code 405 for "Myurl"
**Try this one **
private void sendWorkPostRequest() {
try {
String URL = "";
JSONObject jsonBody = new JSONObject();
jsonBody.put("email", "abc#abc.com");
jsonBody.put("password", "");
jsonBody.put("user_type", "");
jsonBody.put("company_id", "");
jsonBody.put("status", "");
JsonObjectRequest jsonOblect = new JsonObjectRequest(Request.Method.POST, URL, jsonBody, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Toast.makeText(getApplicationContext(), "Response: " + response.toString(), Toast.LENGTH_SHORT).show();
}
}, new Response.ErrorListener() {

I have an alternative answer that works pretty well for Android Volley+ library by dworks and Google: See HERE
From two days i am trying to solve this issue but still i have no any result,why each and every time volley returning me 403 error. where i m wrong? i am using postman to check same webservice, it returns success result. But same thing when i am using in Android via volley or httpurlconnection getting 403 error.kindly help me to find my error.
This is my code which i have tried:
StringRequest jsonObjectRequest = new StringRequest(Request.Method.POST, Constant.posturl, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
String result=response;
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
NetworkResponse response = error.networkResponse;
int status = response.statusCode;
}
}) {
#Override
public Map<String, String> getHeaders() {
try {
headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
String credentials = Constant.USERNAME + ":" + Constant.PASSWORD;
String auth = "Basic " + Base64.encodeToString(credentials.getBytes(), Base64.DEFAULT);
headers.put("Authorization", auth);
return headers;
} catch (Exception e) {
e.printStackTrace();
return headers;
}
}
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("title", heading_edit_text.getText().toString());
params.put("content", body_edit_text.getText().toString());
params.put("Slug", heading_edit_text.getText().toString());
params.put("date", currentDate);
return params;
}
};
jsonObjectRequest.setRetryPolicy(new DefaultRetryPolicy(50000, 3, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
requestQueue.add(jsonObjectRequest);
Volley does provide a proper request for this which is called JsonObjectRequest.
String webAddress = "url here";
RequestQueue queue = Volley.newRequestQueue(this); // singletone here
JSONObject object = new JSONObject();
try {
object.put("title", heading_edit_text.getText().toString());
object.put("content", body_edit_text.getText().toString());
object.put("Slug", heading_edit_text.getText().toString());
object.put("date", currentDate);
} catch (JSONException e) {
}
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, webAddress,object, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject object) {
Log.d("RESPONSE", object.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError volleyError) {
Log.d("RESPONSE", "That didn't work!");
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> header = new HashMap<>();
// content type is not needed here
header.put("Authorization", "value here");
return header;
}
};
queue.add(request);
Change the "Content-Type" of your headers to "application/form-data"
ie,
headers.put("Content-Type", "application/form-data");
I was also face this issue in news api. But when I use Retrfit its work like a charm.
In my Android app I have a StringRequest and send it using Volley. The problem is that neither onResponse nor onErrorResponse get called!! I use JSONRequest in other part of my application and I have absolutely no problem with it.
What am I missing?
Here is one of the samples I tried
It's been bugging me for a couple of hours and I have no idea what is causing this. Any clue highly appreciated.
Here is the code:
public class AccountManagerProxy {
StringRequest req;
public void run() {
try {
String s1 = URLEncoder.encode("user", "UTF-8");
String s2 = URLEncoder.encode("pass", "UTF-8");
String uri = String.format("http://****/token?grant_type=password&username=%1$s&password=%2$s", s1, s2);
req = new StringRequest(Request.Method.GET, uri, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
VolleyLog.v("Response:%n %s", response);
Log.d("##", "##");
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.e("Error: ", error.getMessage());
Log.d("##", "##");
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/x-www-form-urlencoded");
return params;
}
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String parsed;
try {
parsed = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
} catch (UnsupportedEncodingException e) {
parsed = new String(response.data);
}
return Response.success(parsed, HttpHeaderParser.parseCacheHeaders(response));
}
}
;
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} Singleton.getInstance().getRequestQueue().add(req);
}
}
