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 Want to post something like this [1,2,14,15] using volley to my PHP file where there's a SQL to retreive data from database.
Here my volley :
Map<String, String> userParams = new HashMap<String, String>();
listParams.put(TAG_IDS, all_ids);
CustomRequest myREquest= new CustomRequest(Request.Method.POST, URL, listParams,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
And in my PHP file i'll use a SQL something like this :
$liste=$_POST['IDS'] ;
$val= array_map('intval', $liste);
$new_liste = implode("','", $val);
$query = "SELECT * table WHERE IDS IN('".$new_liste ."')";
Here my CustomRequest
public class CustomRequest extends Request<JSONObject> {
private Response.Listener<JSONObject> listener;
private Map<String, String> params;
public CustomRequest(String url, Map<String, String> params, Response.Listener<JSONObject> reponseListener,
Response.ErrorListener errorListener){
super(Method.GET, url, errorListener);
this.listener=reponseListener;
this.params= params;
}
public CustomRequest(int methode, String url, Map<String, String> params, Response.Listener<JSONObject> reponseListener,
Response.ErrorListener errorListener){
super(methode,url,errorListener);
this.listener = reponseListener;
this.params = params;
}
protected Map<String, String> getParams()
throws com.android.volley.AuthFailureError{
return params;
}
#Override

}catch (JSONException je){
return Response.error(new ParseError(je));
}
}
#Override

listener.onResponse(response);
}
}
Please help.
You should iterate your all_ids and put all of them in Map which will be send to the server. For example:
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<>();
for(int i=0; i<all_ids.size(); i++) {
params.put(TAG_IDS + "[" + i + "]", all_ids.get(i).toString());
}
return params;
}
CustomRequest.java
public class CustomRequest extends Request<JSONObject> {
private Listener<JSONObject> listener;
private Map<String, String> params;
private Map<String, String> headers;
public CustomRequest(String url,
Map<String, String> params,
Map<String, String> headers,
Listener<JSONObject> reponseListener,
ErrorListener errorListener) {
super(Method.GET, url, errorListener);
this.listener = reponseListener;
this.params = params;
this.headers = headers;
}
public CustomRequest(int method,
String url,
Map<String, String> params,
Map<String, String> headers,

ErrorListener errorListener) {
super(method, url, errorListener);
this.listener = reponseListener;
this.params = params;
this.headers = headers;
}
protected Map<String, String> getParams()
throws com.android.volley.AuthFailureError {
return params;
};
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
return headers != null ? headers : super.getHeaders();
}
#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 e) {
return Response.error(new ParseError(e));
} catch (JSONException je) {
return Response.error(new ParseError(je));

I am using request like this in my class:
Map<String, String> params = new HashMap<>();
Map<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
Iterator it = params.entrySet().iterator();
while (it.hasNext()) {
Map.Entry pairs = (Map.Entry) it.next();
Log.d(context.getClass().getCanonicalName(), "params - " + pairs.getKey() + ", " + pairs.getValue());
}
String url = AppConstants.SERVER_URL + mApi + "/" + mType+ "/" +mWord.getID();
Log.d("FinalUrl:->", url);
RequestQueue requestQueue = Volley.newRequestQueue(ActDrawAreaTwo.this);
CustomRequest jsObjRequest = new CustomRequest(Request.Method.PUT,
url,
params,
headers,
this.createRequestSuccessListener(),
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
progress.dismiss();
}
});
RequestQueueHelper.addToRequestQueue(jsObjRequest, "");
I am getting error:
11-22 10:28:01.605 17921-18491/com.app.admin E/Volley: [3516] BasicNetwork.performRequest: Unexpected response code 500
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!
Server is not accepting String parameters when making json object request (by post method) using volley, also in custom volley request it is required to pass a string Hash map in getParams() method i am having string as well as long values to be pass over there, Also tried by Uri class but there is also sting is required in appendQueryParameter(). i have used below links Link 1
Link 2 Link 3

}
}
#Override

}
}
You first need to convert the long parameter to String using String.valueOf(long value) method and then put this param to the hashmap with its key. as:
params.put("key", String.valueOf(long value));
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;
}
}
I am trying create a custom BasicAuthentication with Volley. I have a class ApplicationController that I implemented methods getHeaders and works fine with all application, but now, I have a method that I need send other BasicAuthentication with other Parameters. To do it I am trying #Override the getHeaders() of class ApplicationController. It doesnt works and return a exception.
How can I do it ?
