public void check_spinner() {
JsonRequest stringRequest = new JsonRequest(Request.Method.POST, Base_Url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
// Toast.makeText(Spinner_Activity.this, response.toString(), Toast.LENGTH_SHORT).show();
if (response.getString("error").equalsIgnoreCase("false")) {
int daily = response.getInt("daily");
int left = response.getInt("left");
int leftt = daily-left;
spins.setText(leftt+" spin mövcuddur");
if (left>=daily)
{ spin_btn.setEnabled(false); }else { spin_btn.setEnabled(true); }
} else {
Toast.makeText(VideoActivity.this, response.getString("message"), Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_SHORT).show();
}

I'm trying to replace json object with json array but i'm beginner and i can't do this. When i change it, getting errors.

Volley POST Request with headers and raw json body

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);
setContentView(R.layout.activity_main);
loginEmail = (EditText)findViewById(R.id.etUsername);
loginPassword = (EditText)findViewById(R.id.etPassword);
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) {
Toast.makeText(MainActivity.this, response, Toast.LENGTH_LONG).show();
startActivity(new Intent(MainActivity.this, LandingPage.class));
finish();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this, "Error", Toast.LENGTH_LONG).show();
NetworkResponse response = error.networkResponse;
if (error instanceof ServerError && response != null) {
try {
String res = new String(response.data,
HttpHeaderParser.parseCharset(response.headers, "utf-8"));
// Now you can use any deserializer to make sense of data
JSONObject obj = new JSONObject(res);
Toast.makeText(MainActivity.this, res, Toast.LENGTH_LONG).show();
Log.i("MainActivity", res);
//use this json as you want
} catch (UnsupportedEncodingException e1) {
// Couldn't properly decode data to string
e1.printStackTrace();
} catch (JSONException e2) {
// returned data is not JSONObject?
e2.printStackTrace();
}
}
}
})
{
#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
public Map<String, String> getHeaders() throws AuthFailureError {

return params;
}
};
RequestQueue rQueue = Volley.newRequestQueue(MainActivity.this);
rQueue.add(request);
}
});
}
}
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);

Volley JsonObjectRequest with Basic Auth headers didn't work

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.

Its a put request, its working in postman

According to your Postman screenshot, I suggest you use the following sample code:
String url = "http://...";
JSONObject jsonBody;
try {
jsonBody = new JSONObject();
jsonBody.put("ID", 1);
jsonBody.put("Name", "Word1");
jsonBody.put("ArabicName", "Arabic Word1");
// other key-value pairs...
JsonObjectRequest request = new JsonObjectRequest(Request.Method.PUT, url, jsonBody, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// do something
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// do something
}
});
queue.add(request);
} catch (JSONException e) {
e.printStackTrace();
}
Hope this helps!
