How do I send a POST request using Volley - android

So I have this customer, and I want to update the fcm_token value in the customer object via post request using volley, but It's not working..!
See the json link >> http://www.mocky.io/v2/5911638a1200001e020fb5d2
My attempt so far..
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
#Override
public void onTokenRefresh() {
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String token) {
RequestQueue requestQueue = Volley.newRequestQueue(this);
HashMap<String, String> params = new HashMap<String, String>();
params.put("fcm_token", token);
Customer me = Hawk.get("user");
String URL = API_URLs.TokenURL(me.getID());
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method
.POST, URL, new JSONObject(params),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
//Log
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
//Log
}
}
);
requestQueue.add(jsObjRequest);
UPDATE
I change request to this and still didn't change..!?
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
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) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("fcm_token", token);
return params;
}
};
requestQueue.add(jsonObjReq);
UPDATE 2
so after a lot of attempts still not solved, but I'm gonna explain what I want to do exactly maybe you will get what I want to accomplish, I wanna send my device fcm token to server based on the user id when login, so I have a Customer model class that has the value of fcm_token it must after the request is made it must be set as my token, the process happens in web server btw.
Here's my code so far..
MyFirebaseInstanceIDService Class
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
String refreshedToken;
#Override
public void onTokenRefresh() {
refreshedToken = FirebaseInstanceId.getInstance().getToken();
Hawk.put("token", refreshedToken);
}
public static void sendRegistrationToServer(Context context) {
}
}
Customer Model Class
public class Customer {
#SerializedName("avatar_url")
#Expose
private String cusPicURL;
#SerializedName("first_name")
#Expose
private String firstName;
#SerializedName("last_name")
#Expose
private String lastName;
#SerializedName("fcm_token")
#Expose
private String token;
public String getToken() {
return token;
}
public void setToken(String token) {
this.token = token;
}
// ..... more variables & setters and getters
My Request Code inside a repository class (all request are here..)
public static void UpdateFCM_Token(final Context context, final String token) {
RequestQueue requestQueue = Volley.newRequestQueue(context);
Customer me = Hawk.get("user");
Log.i("USER ID: ", "" + me.getID());
String URL = API_URLs.TokenURL(me.getID());
JsonObjectRequest req = new JsonObjectRequest(Request.Method.POST,
URL, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONObject o = response.getJSONObject("customer");
Gson gson = new Gson();
Customer customer = gson.fromJson(o.toString(), Customer.class);
} catch (JSONException e) {
e.printStackTrace();
}
Log.d("FCM OnResponse", response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d("FCM Error: ", "" + error.getMessage());
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("fcm_token", token);
return params;
}
};
requestQueue.add(req);
}
The fragment in MainActivity
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// code..
String token = Hawk.get("token");
Log.i("TOKEN", token);
DriverRepository.UpdateFCM_Token(getActivity(), token);
return rootView;
}
The Logs

Hey you suppose to add Map + remove null from new JsonObjectRequest(.......null,listener....):
private void sendRegistrationToServer(String token) {
RequestQueue requestQueue = Volley.newRequestQueue(this);
HashMap<String, String> params = new HashMap<String, String>();
params.put("fcm_token", token);
Customer me = Hawk.get("user");
String URL = API_URLs.TokenURL(me.getID());
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST, url,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
//Log
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
//Log
}
}
){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String,String> map = new HashMap();
//add your params here to the map
return map;
}
};
requestQueue.add(jsObjRequest);

You may have to override getParams of JsonObjectRequest and pass your POST params.
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method
.POST, URL, null, listener, errorListener){
protected Map<String,String> getParams() throws AuthFailureError{
return postParamsMap;
}
}
You can also use StringRequest instead of JsonObjectRequest.
StringRequest jsonObjReq = new StringRequest(Request.Method.POST,
URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d(TAG, response);
//Converting the response to JSON
JSONObject jsonObj = new JSONObject(response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("fcm_token", token);
return params;
}
};
requestQueue.add(jsonObjReq);

after some works, I solved it using okhttp3 since volley didn't work for me, although the rest of request in my app are using volley but this one is only okhttp3, I hope that's not a bad practice.
Thanks a lot guys for ur help..!
here's the code in my request method.. in case someone might have the same problem.
public static void UpdateFCM_Token(final String token) {
Customer me = Hawk.get("user");
Log.i("USER ID: ", "" + me.getID());
String URL = API_URLs.TokenURL(me.getID());
OkHttpClient client = new OkHttpClient();
String json = "{\"fcm_token\":\"" + token + "\"}";
Log.i("Json : ", json);
MediaType mediaType = MediaType.parse("application/json");
RequestBody body = RequestBody.create(mediaType, json);
okhttp3.Request request = new okhttp3.Request.Builder()
.url(URL)
.post(body)
.addHeader("content-type", "application/json")
.build();
try {
okhttp3.Response response = client.newCall(request).execute();
isTokenSent = true;
Log.i("response ", response + "");
} catch (IOException e) {
e.printStackTrace();
Log.i("IOException", "" + e);
}
}

How to send parameters to backend, and get response message, using GET method in volley, android?

I want to send three parameters "guestEmail", "latitude" and "longitude" to backend and get a message of success from backend if it is successful.
I have tried doing this:
public void myGetFunc()
{
final String url = "....";
// prepare the Request
JsonObjectRequest getRequest = new JsonObjectRequest(Request.Method.GET, url, null,
new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response) {
// display response
Log.d("Response", response.toString());
Toast.makeText(getApplicationContext(), response.toString(), Toast.LENGTH_SHORT).show();
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
Log.d("Error.Response", response);
}
}
)
{
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String> ();
params.put("guestEmail", "abc#xyz.com");
params.put("latitude", "12");
params.put("longitude", "12");
return params;
}
};
// add it to the RequestQueue
queue.add(getRequest);
}
This method is invoked when the 'SOS' button is clicked.
But right now, nothing happens on clicking the 'SOS' button.
Please help!
If you are going to use GET you query parameters and build the string yourself
private static final String URL = "http://www.test.com?value1={val1}&value2={val2}";
String requestString = URL;
requestString.replace("{val1}", "1");
requestString.replace("{val2}", "Bob");
StringRequest strreq = new StringRequest(Request.Method.GET,
requestString,
new Response.Listener<String>() {
#Override
public void onResponse(String Response) {
// get response
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError e) {
e.printStackTrace();
}
});
Volley.getInstance(this).addToRequestQueue(strreq);
If you are going to use POST us a body
public class LoginRequest extends Request<String> {
// ... other methods go here
private Map<String, String> mParams;
public LoginRequest(String param1, String param2, Listener<String> listener, ErrorListener errorListener) {
super(Method.POST, "http://test.url", errorListener);
mListener = listener;
mParams = new HashMap<String, String>();
mParams.put("paramOne", param1);
mParams.put("paramTwo", param2);
}
#Override
public Map<String, String> getParams() {
return mParams;
}
}
If you want to pass parameters than you need to use POST method otherwise for GET , just pass values in URL itself.

WebAPI call using volley

I'm trying to get access tokens from the server using a volley String request. I have tried making a JsonObjectRequest also. Both are below.
public void getAuthenticationTokens(Object param1, final CustomListener<String> listener)
{
//String url = prefixURL + "this/request/suffix";
String url = "https://lw.xxx.co.uk/connect/token";
StringRequest request = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response) {
// response
Log.e("Response", response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
// error
Log.e("Error.Response", error.networkResponse.toString());
}
}
) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> params = new HashMap<>();
params.put("Content-Type","application/x-www-form-urlencoded");
//..add other headers
return params;
}
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String> ();
params.put("scope", "openid email phone profile offline_access roles");
params.put("resource", "window.location.origin");
params.put("grant_type", "password");
params.put("username", "support#xxx.com");
params.put("password", "tempPxxx");
return params;
}
};
requestQueue.add(request);
.
public void getAuthenticationTokens(Object param1, final CustomListener<String> listener)
{
//String url = prefixURL + "this/request/suffix";
String url = "https://lw.xxx.co.uk/connect/token";
Map<String, Object> jsonParams = new HashMap<>();
jsonParams.put("scope", "openid email phone profile offline_access roles");
jsonParams.put("resource", "window.location.origin");
jsonParams.put("grant_type", "password");
jsonParams.put("username", "support#xxx.com");
jsonParams.put("password", "tempPxxx");
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, new JSONObject(jsonParams),
new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response)
{
Log.d(TAG + ": ", "somePostRequest Response : " + response.toString());
if(null != response.toString())
listener.getResult(response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error)
{
if (null != error.networkResponse)
{
Log.e(TAG + ": ", "Error Response code: " + error.networkResponse.statusCode);
listener.getResult(null);
}
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
// Map<String,String> params = super.getHeaders();
// if(params==null)params = new HashMap<>();
Map<String,String> params = new HashMap<>();
params.put("Content-Type","application/x-www-form-urlencoded");
//..add other headers
return params;
}
};
requestQueue.add(request);
.
I get the following response from the server:
E/Volley: [31388] BasicNetwork.performRequest: Unexpected response code 400 for https://lw.xxx.co.uk/connect/token
.
My colleague who has written the server-side code has asked how to convert the following Angular code (his code that works with the API), to Android.
Can anyone help with this?
getLoginEndpoint(userName: string, password: string): Observable<Response> {
let header = new Headers();
header.append("Content-Type", "application/x-www-form-urlencoded");
let searchParams = new URLSearchParams();
searchParams.append('username', userName);
searchParams.append('password', password);
searchParams.append('grant_type', 'password');
searchParams.append('scope', 'openid email phone profile offline_access roles');
searchParams.append('resource', window.location.origin);
let requestBody = searchParams.toString();
return this.http.post(this.loginUrl, requestBody, { headers: header });
}
The problem was a couple of things.
I replaced "params.put("resource", "window.location.origin"); " with "params.put("resource", "https://lw.xxx.co.uk");"
Also, I found out that Volley ignore the getHeaders override, so I commented that method out and used the following to set the headers.
#Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded";
}
public void getAuthenticationTokens(Object param1, final String userName, final String password, final CustomListener<JSONObject> listener)
{
String url = "https://lw.xxx.co.uk/connect/token";
StringRequest request = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response) {
// response
Log.e("Response", response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
// error
Log.e("Error.Response", error.networkResponse.toString());
}
}
) {
/* #Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> params = new HashMap<>();
params.put("Content-Type","application/x-www-form-urlencoded");
//..add other headers
return params;
}*/
#Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded";
}
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String> ();
params.put("scope", "openid email phone profile offline_access roles");
params.put("resource", "https://lw.xxx.co.uk");
params.put("grant_type", "password");
params.put("username", userName);
params.put("password", password);
return params;
}
#Override

try {
String json = new String(response.networkResponse.data, HttpHeaderParser.parseCharset(response.networkResponse.headers));
Log.e(TAG, "reponse error = " + json);

return super.parseNetworkError(response);

Android volley post methode parameter missing

I am using android volley library to post data to back-end service. But I can't send any parameter with my request. I have done each and everything mentioned here . But none works for me. The post method that I am using is:
public static void post()
{
// Tag used to cancel the request
String tag_json_obj = "json_obj_req";
String url = "http://myUrl";
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
url, obj,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("TAG", response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d("TAG", "Error: " + error.getMessage());
}
}) {
/**
* Passing some request headers
* */
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
return headers;
}
#Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded";
}
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("key", "value");
return params;
}
};
// Adding request to request queue
AppController.getInstance().addToRequestQueue(jsonObjReq, tag_json_obj);
}
Always the response is "parameter missing".
How could i resolve this issue?
If you're using JSONObjectRequest, you can try this.
String url = "http://myurl";
Map<String, String> params = new HashMap<String, String>();
params.put("key", value);
RequestQueue queue = Volley.newRequestQueue(getActivity());
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST,
url, new JSONObject(params),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject jsonObject) {
try {
success = jsonObject.getInt("success");
message = jsonObject.getString("message");
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError volleyError) {
Activity activity = getActivity();
if (volleyError instanceof NoConnectionError) {
String errormsg = "Check your internet connection";
Toast.makeText(activity, errormsg, Toast.LENGTH_LONG).show();
}
}
});
queue.add(jsonObjectRequest);
The codes are more likely the same as yours. Check on the lines where I put the data to be posted. I'm very sure this would work!
The problem is you are approaching the request as though you were making a stringRequest. The link you reference is talking specifically about making a stringRequest.
jsonObjectRequest actually lets you put the json object into the constructor itself, instead of using the override method getParams() like so:
String url = "some_url";
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put(Constants.LOGIN_EMAIL_ID, email);
jsonObject.put(Constants.LOGIN_PASSWORD, password);
}catch(JSONException e){
Log.d("JSON error", e.getMessage(), e);
}
JsonObjectRequest jsObjRequest = new JsonObjectRequest(url, jsonObject, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("RESPONSE", response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
if(error.getMessage()!=null){
Log.d("RESPONSE", error.getMessage());
}
}
});
VolleySingleton.getInstance(activity).getRequestQueue().add(jsObjRequest);

How to send a POST request using volley with string body?

I'm developing an Android app that communicate with a RESTful web service I wrote. Using Volley for GET methods is awesome and easy, but I can't put my finger on the POST methods.
I want to send a POST request with a String in the body of the request, and retrieve the raw response of the web service (like 200 ok, 500 server error).
All I could find is the StringRequest which doesn't allow to send with data (body), and also it bounds me to receive a parsed String response.
I also came across JsonObjectRequest which accepts data (body) but retrieve a parsed JSONObject response.
I decided to write my own implementation, but I cannot find a way to receive the raw response from the web service. How can I do it?
You can refer to the following code (of course you can customize to get more details of the network response):
try {
RequestQueue requestQueue = Volley.newRequestQueue(this);
String URL = "http://...";
JSONObject jsonBody = new JSONObject();
jsonBody.put("Title", "Android Volley Demo");
jsonBody.put("Author", "BNK");
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();
}
I liked this one, but it is sending JSON not string as requested in the question, reposting the code here, in case the original github got removed or changed, and this one found to be useful by someone.

I created a function for a Volley Request. You just need to pass the arguments :

RequestQueue MyRequestQueue = Volley.newRequestQueue(this);
String url = "http://your_url.com/abc.php"; // <----enter your post url here
StringRequest MyStringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
//This code is executed if the server responds, whether or not the response contains data.
//The String 'response' contains the server's response.
}
}, new Response.ErrorListener() { //Create an error listener to handle errors appropriately.
#Override
public void onErrorResponse(VolleyError error) {
//This code is executed if there is an error.
}
}) {
protected Map<String, String> getParams() {
Map<String, String> MyData = new HashMap<String, String>();
MyData.put("username", username);
MyData.put("password", password);
return MyData;
}
};
MyRequestQueue.add(MyStringRequest);
}

Android Volley POST JsonObject and get JsonArray or JsonObject or Other response

in volley we have some ability to retrieve data from server such as jsonObject,jsonArray and String. in this below sample we can get simply jsonObject or jsonArray response from server,
public static void POST(HashMap<String, String> params, final Listeners.ServerResponseListener listener) {
JsonObjectRequest req1 = new JsonObjectRequest(ApplicationController.URL, new JSONObject(params),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.e("Response:", response.toString());
if (listener != null)
listener.onResultJsonObject(response);
else
Log.e(TAG,"Error: SetServerResponse interface not set");
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("Error: ", error.getMessage());
}
});
ApplicationController.getInstance().addToRequestQueue(req1);
}
my problem is i want to send jsonObject from this method and get jsonArray or jsonObject from server, and i can not get simply array from server with this method. for example i must be filter server response with this jsonObject:
HashMap<String, String> params = new HashMap<String, String>();
params.put("token", "AbCdEfGh123456");
params.put("search_count", "10");
params.put("order_by", "id");
server return jsonArray and i can not get that with Volley response
Looking at the source code of JsonArrayRequest. There is a constructor which takes in a JSONObject. You should check it out
public class RetreiveData {
public static final String TAG = RetreiveData.class.getSimpleName();
public static void POST(String localhost, final HashMap<String, String> params, final Listeners.ServerResponseListener listener) {
StringRequest post = new StringRequest(Request.Method.POST, localhost, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
if (listener != null)
listener.onResponse(response.toString());
else
Log.e(TAG, "Error: SetServerResponse interface not set");
} catch (Exception e) {
e.printStackTrace();
Log.d("Error: ", e.getMessage());
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("Error: ", error.toString());
}
}) {
