I need to get the cookies from server response. For network calling i am using volley library.
getRequest(String url, Response.Listener<JSONObject> responseListener, Response.ErrorListener errorListener) {
try {
JsonObjectRequest req = new JsonObjectRequest(Request.Method.GET, url, null, responseListener
, errorListener) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
return getAuthHeader(context);
}
};
RetryPolicy policy = new DefaultRetryPolicy(socketTimeout, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
req.setRetryPolicy(policy);
req.setShouldCache(false);
addToRequestQueue(req);
} catch (Exception e) {
e.printStackTrace();
}
public static Map<String, String> getAuthHeader(Context context) {
Map<String, String> headerMap = new HashMap<>();
headerMap.put("token", auth);
headerMap.put("Api-key", API_KEY);
headerMap.put("Content-Type", CONTENT_TYPE);
return headerMap;
}
StringRequest req = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("response",response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.i("error",error.getMessage());
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
return getAuthHeader(context);
}
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
// since we don't know which of the two underlying network vehicles
// will Volley use, we have to handle and store session cookies manually
Log.i("response",response.headers.toString());
Map<String, String> responseHeaders = response.headers;
String rawCookies = responseHeaders.get("Set-Cookie");
Log.i("cookies",rawCookies);
return super.parseNetworkResponse(response);
}
};

I have Url for Login. Its working and give response in Postman and Retrofit but not working with volley.
In volley its give error: com.android.volley.RedirectError
Why i geeting RedirectError. url working and give response in retrofit as well in postman.
Here is my Code:
public void Login(){
final String REGISTER_URL = "Here_My_Url";
StringRequest stringRequest = new StringRequest(Request.Method.POST, REGISTER_URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("onResponse", response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("eee123",error.toString());
Toast.makeText(getApplicationContext(), error.getMessage(),
Toast.LENGTH_SHORT).show();
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("user_email", st_email);
params.put("password", st_pass);
Log.e("params", " " + params);
}
return params;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
headers.put("Content-Type", "application/json");
return headers;
}
};
stringRequest.setRetryPolicy(new DefaultRetryPolicy(0, -1,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
stringRequest.setShouldCache(false);
VolleySingleton.getInstance(this).addToRequestQueue(stringRequest);
}
I am trying to retrieve a response from my server in my Android App but getting "com.android.volley.ServerError"
E/Volley: [224669] BasicNetwork.performRequest: Unexpected response code 400 for http://52.74.115.250:8080/api/products
When I try in Postman,I do get a response.
This is my code for GET request:
JsonObjectRequest jsonObjectRequest=new JsonObjectRequest(Request.Method.GET, Constants.productListUrlStr, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("jsonsucces","success");
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("jsonerror",error.toString());
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
headers.put("Authorization", Constants.getToken(getActivity()));
//headers=globalProvider.addHeaderToken(getActivity());
return headers;
}
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
if (contract!=null){
if(contract._supplier!=null){
Log.d("checksupplier",contract._supplier);
params.put("_supplier",contract._supplier);
}
}
if(!globalProvider.ShangpingHeaderLoadCategory .equals("")){
params.put("category",globalProvider.ShangpingHeaderLoadCategory);
Log.d("checkcategoryhe",globalProvider.ShangpingHeaderLoadCategory);
}
return params;
}
};
globalProvider.addRequest(jsonObjectRequest);
what am I doing wrong?
There are few posts about getParams() not working anymore for JsonObjectRequest volley request.
Alternatively either you can use StringRequest or do a little tweak in your request as below
JSONObject jOb = new JSONObject();
try {
jOb.put("_supplier", contract._supplier);
jOb.put("category", globalProvider.ShangpingHeaderLoadCategory);
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, Constants.productListUrlStr, jOb, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("jsonsucces","success");
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("jsonerror",error.toString());
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
headers.put("Authorization", Constants.getToken(getActivity()));
//headers=globalProvider.addHeaderToken(getActivity());
return headers;
}
};
I figured out,Since I am passing query parameter I was constructing my url incorrectly.
String uri= String.format(Constants.productListUrlStr+"?_supplier=%1$s",contract._supplier);
StringRequest stringRequest=new StringRequest(Request.Method.GET, uri, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("checksuc",response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("checkstrerr",error.networkResponse.headers.toString());
}
})
{
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
headers.put("Authorization", Constants.getToken(getActivity()));
//headers=globalProvider.addHeaderToken(getActivity());
return headers;
}
}
;
globalProvider.addRequest(stringRequest);
I have a Volley Request code
RequestQueue queue = Volley.newRequestQueue(this);
String url =<My URL>;
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
mTextView.setText("Response is: "+ response.substring(0,500));
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mTextView.setText("That didn't work!");
}
});
// Add the request to the RequestQueue.
queue.add(stringRequest);
How do I set a header called Authorization in this??
Override getHeaders in request like:
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
mTextView.setText("Response is: "+ response.substring(0,500));
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mTextView.setText("That didn't work!");
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> params = super.getHeaders();
if(params==null)params = new HashMap<>();
params.put("Authorization","Your authorization");
//..add other headers
return params;
}
};
you can write a class extends Request.(override getHeaders() and so on)
just like
public abstract class AbsRequest<T> extends Request<T>{
public AbsRequest(int method, String url, Response.ErrorListener listener) {
this(method, url, null, listener);
}
public AbsRequest(int method, String url, Map<String, String> params, Response.ErrorListener listener) {
this(method, url, params, null, listener);
}
public AbsRequest(int method, String url, Map<String, String> params, Map<String, String> head, Response.ErrorListener listener) {
this(method, url, params, head, null, listener);
}
public AbsRequest(int method, String url, Map<String, String> params, Map<String, String> head, String bodyContentType, Response.ErrorListener listener) {
this(method, url, params, null, head, bodyContentType, listener);
}
public AbsRequest(int method, String url, String body, Map<String, String> head, String bodyContentType, Response.ErrorListener listener) {
this(method, url, null, body, head, bodyContentType, listener);
}
private AbsRequest(int method, String url, Map<String, String> params, String body, Map<String, String> head, String bodyContentType, Response.ErrorListener listener) {
super(method, url, listener);
}
}
for more information you can see https://github.com/Caij/CodeHub/blob/master/lib/src/main/java/com/caij/lib/volley/request/AbsRequest.java
how to use can see https://github.com/Caij/CodeHub/tree/master/app/src/main/java/com/caij/codehub/presenter/imp
A call to super.getHeaders() throws UnSupportedOperationException.
remove super.getHeaders() to get rid off that.
This here is a sample volley request showing how to add headers
private void call_api(final String url){
if(!this.isFinishing() && getApplicationContext() != null){
new Handler(Looper.getMainLooper()).post(new Runnable() {
#Override
public void run() {

Log.e("APICALL", "\n response: " + response);
if(!FinalActivity.this.isFinishing()){
try {

last_results_type = k.getString("type");
new Handler(Looper.getMainLooper()).post(new Runnable() {
#Override

RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
requestQueue.add(stringRequest);
}
}
Android volley library is not accepting parameters from getParam() method.If it is given in query String then it works.I tried both GET and POST it doesn't works. But I want to give parameters POST Method.please check the code I have posted below.
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
String url = AppConstants.WEBSERVICE_URL
+ AppConstants.WEBSERVICE_URL_POST_COMMENT;
StringRequest getRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// response
Log.d("Response_postComment", response);
Intent intent = new Intent(getApplicationContext(),
ReviewActivity.class);
intent.putExtra("serviceId", servicePosition);
startActivity(intent);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// error
Log.d("Error.Response", error.toString());
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> pars = new HashMap<String, String>();
pars.put("Content-Type", "application/x-www-form-urlencoded");
return pars;
}
#Override
protected Map<String, String> getParams() throws AuthFailureError{
Map<String, String> params = new HashMap<String, String>();
params.put("rating", ratingBar.getRating() + "");
params.put("com_content", comments.getText() + "");
params.put("user_id", AppConstants.APP_LOGIN_USER_ID);
params.put("comm_post_ID", AppConstants.arrListServiceDetail
.get(servicePosition).getId() + "");
return params;
}
};
getRequest.setRetryPolicy(new DefaultRetryPolicy(500000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
queue.add(getRequest);
getParam() method not working with GET request on volley.its working fine with POST methods.you have to set up complete URL with parameters.
I faced the same issue as you are facing now, but comes up with solution of making a custom request by making the core class Request as the super class of this request. In this i am passing params in constructor, then returning it to the getParams() overridden method as below:
public class RequestJson extends Request<JSONObject> {
private Listener<JSONObject> listener;
private Map<String, String> params;
public RequestJson(String url, Map<String, String> params,
Listener<JSONObject> reponseListener, ErrorListener errorListener) {
super(Method.GET, url, errorListener);
this.listener = reponseListener;
this.params = params;
}
public RequestJson(int method, String url, Map<String, String> params,
Listener<JSONObject> reponseListener, ErrorListener errorListener) {
super(method, url, errorListener);
this.listener = reponseListener;
this.params = params;
}
protected Map<String, String> getParams()
throws com.android.volley.AuthFailureError {
return params;
};
#Override
protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
AppController.getInstance().checkSessionCookie(response.headers);
try {
String jsonString = new String(response.data,
HttpHeaderParser.parseCharset(response.headers));
return Response.success(new JSONObject(jsonString),
HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JSONException je) {
return Response.error(new ParseError(je));
}
}
#Override
protected void deliverResponse(JSONObject response) {
// TODO Auto-generated method stub
listener.onResponse(response);
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = super.getHeaders();
if (headers == null
|| headers.equals(Collections.emptyMap())) {
headers = new HashMap<String, String>();
}
AppController.getInstance().addSessionCookie(headers);
return headers;
}
}
Hope this will solve your problem.
I start using Volley for my application and I want to add custom headers for each request as a security identifier.
I'm using a JsonObjectRequest and overriding the getHeaders().
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET,
url,
null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d(TAG, error.toString());
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<>();
String mApiKey = "123";
headers.put("APIKEY", mApiKey);
return headers;
}
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("param1", "1");
params.put("param2", "2");
params.put("param3", "3");
return params;
}
};
VolleySingleton.getInstance(getActivity()).addToRequestQueue(jsonObjectRequest);
But I get this error:
E/Volley﹕ [23620] BasicNetwork.performRequest: Unexpected response code 401 for http://...
The AuthFailureError is thrown.
I also try to use StringRequest but same error.
If someone is in the same case and have solution, thank you in advance!
This is a basic concept how to override a header in a standard VolleyRequest
VolleyRequest networkRequest = new VolleyRequest(request.getHttpMethod(), mUrlBase + request.getUrlSuffix(), responseListener, errorListener) {
public String getBodyContentType() {
return "application/json; charset=" + getParamsEncoding();
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> map = new HashMap<String, String>();
map.put("X-Device-Info","Android FOO BAR");
map.put("Accept-Language", acceptLanguage);
map.put("Content-Type", "application/json; charset=UTF-8");
return map;
}
public byte[] getBody() throws AuthFailureError {
try {
String json = request.toJson().toString();
if (json.length() < 3)
return ("{}").getBytes();
// log(json);
return json.getBytes(getParamsEncoding());
} catch (UnsupportedEncodingException e) {
Log.e(TAG, "getBody(): request has no json");
e.printStackTrace();
}
return new byte[0];
}
};
public class CustomJsonObjectRequest extends JsonObjectRequest
{
public CustomJsonObjectRequest(int method, String url, JSONObject jsonRequest,Response.Listener listener, Response.ErrorListener errorListener)
{
super(method, url, jsonRequest, listener, errorListener);
}
#Override
public Map getHeaders() throws AuthFailureError {
Map headers = new HashMap();
headers.put(Constants.accesstoken, Globals.getInstance().getAccessToken());
Logger.debugE(Constants.accesstoken, headers.toString());
return headers;
}
}
