post request with passing list in body using volley

post request with passing list in body using volley - android

i have created spring boot api and now i am integrating it with android app in post request i pass a list while testing from postman and it worked well but it did not work while i send list from android. please tell me how to send a list in a body of json with volley library this is image of postman
this is my code
RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
JSONObject jsonBody = new JSONObject();
List<Integer> ids=new ArrayList<>();
ids.add(11);
ids.add(12);
jsonBody.put("ids",ids);
final String mRequestBody = jsonBody.toString();
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL_ADD_SKILLS, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("LOG_RESPONSE", response);
}
}, error -> Log.e("LOG_VOLLEY", error.toString())) {
#Override
public String getBodyContentType() {
return "application/json";
}
#Override
public byte[] getBody() throws AuthFailureError {
try {
return mRequestBody == null ? null : mRequestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", mRequestBody, "utf-8");
return null;
}
}
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String responseString = "";
if (response != null) {
responseString = String.valueOf(response.statusCode);
}
return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
}
};
requestQueue.add(stringRequest);

because you are passing wrong json format to post API like below.
{
"ids": "[11, 12]"
}
but in postman you are passing jsonarray ids in object.
{
"ids":[11,12]
}
so make change in your code like this
JSONObject jsonBody = new JSONObject();
JSONArray jArrIds=new JSONArray();
jArrIds.put(11);
jArrIds.put(12);
jsonBody.put("ids",jArrIds);

Best way to call Volley network call multiple times

I have one requirement, where I have to call Volley POST method near about 300-500 times. In post I am sending JSONObject and in response I am getting String as output. But my problem is when I call volley on some devices I am getting java.lang.OutOfMemoryError because calling service more than 300 times. Following is my code:
for (int i=0;i<myJsonArr.length();i++) // here myJsonArr may contains 300-500 json object
{
customRequestTest(allAppJson.getJSONObject(i));
}
public void customRequestTest(JSONObject jsonObject)
{
try {
String myURL = "My URL";
RequestQueue requestQueue = Volley.newRequestQueue(this);
final String mRequestBody = jsonObject.toString();
System.out.println (">>>>>>>>>>mRequestBody"+mRequestBody);
StringRequest stringRequest = new StringRequest(Request.Method.POST, myURL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("LOG_RESPONSE", response);
System.out.println (">>>>>>>>onResponse"+response +" for request "+mRequestBody);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("LOG_RESPONSE", error.toString());
System.out.println (">>>>>>>>onErrorResponse"+error.toString()+" for request "+mRequestBody);
}
}) {
#Override
public String getBodyContentType() {
return "application/json; charset=utf-8";
}
#Override
public byte[] getBody() throws AuthFailureError {
try {
return mRequestBody == null ? null : mRequestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", mRequestBody, "utf-8");
return null;
}
}
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String responseString = "";
if (response != null) {
String str = new String(response.data);
responseString = str;
}
return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
}
};
requestQueue.add(stringRequest);
} catch (Exception e) {
System.out.println (">>>>>>>>Inside catch of customRequestTest");
e.printStackTrace();
}
}
getting Out of memory erorr at : RequestQueue requestQueue = Volley.newRequestQueue(this);

Microsoft Computer Vision API with android volley response code 400

I'm having some trouble getting JSON response from Microsoft custom vision API (Optical Character Recognition API) when using Android Volley request.
I have used this approach with other API's without any problems, but for this API I cant get it to work.
String URL = "https://westcentralus.api.cognitive.microsoft.com/vision/v1.0/ocr";
final ProgressDialog pDialog = new ProgressDialog(this);
pDialog.setMessage("Getting License plate...");
pDialog.setCancelable(false);
pDialog.show();
try {
RequestQueue requestQueue = Volley.newRequestQueue(this);
JSONObject jsonBody = new JSONObject();
jsonBody.put("url", "https://upload.wikimedia.org/wikipedia/commons/thumb/a/af/Atomist_quote_from_Democritus.png/338px-Atomist_quote_from_Democritus.png");
final String requestBody = jsonBody.toString();
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
pDialog.hide();
Log.i("VOLLEY", response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("VOLLEY", error.toString());
}
}) {
#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 {
HashMap<String, String> headers = new HashMap<>();
headers.put("Content-Type", "application/json");
headers.put("Ocp-Apim-Subscription-Key", "123124123123123123213");
return headers;
}
};
requestQueue.add(stringRequest);
} catch (JSONException e) {
e.printStackTrace();
}
I'm getting this response back:
E/Volley: [2163] BasicNetwork.performRequest: Unexpected response code 400 for https://westcentralus.api.cognitive.microsoft.com/vision/v1.0/ocr
When using postman I'm not getting any errors.
So hope you can see what I'm doing wrong.
Let me know if you want me to elaborate on anything.
Thanks!

You have to replace StringRequest with JsonObjectRequest and get rid of the Content-type header.
This works for me:
final JSONObject jsonBody = new JSONObject();
jsonBody.put("url", "https://pbs.twimg.com/profile_images/808958766628605952/yB14UlXl_400x400.jpg");
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, URL, jsonBody,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
System.out.println(response.toString());
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
String readableError = "";
try {
readableError = new String(error.networkResponse.data, "utf-8");
System.out.println(readableError);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<>();
headers.put("Ocp-Apim-Subscription-Key", "XXXXXXXX");
return headers;
}
};

note we had problems on older devices weirdly.
Was caused by the uploaded image being too big.
Api just returns 400 with no explanation.
ImageHelper class has code to resize image

Android Json Arraylist to Server with Restful Web service

This is my Arraylist which I get from the previous fragment,
listoftags = getArguments().getParcelableArrayList("data");
It works well. Now I have to send this with some parameters like below:
public void volleyJsonObjectRequest(final String SessionID , final String CustomerID, final String ServiceState , final String ServiceID, final String Address, final String PaymentMode, final String CustomerComments , final ArrayList Items){
String REQUEST_TAG = "volleyJsonObjectRequest";
// POST parameters
CustomRequest request = new CustomRequest(Request.Method.POST, url, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// Toast.makeText(SignActivity.this, response.toString(), Toast.LENGTH_SHORT).show();
Log.d("response",""+response.toString());
/* String status = response.optString("StatusMessage");
String actionstatus = response.optString("ActionStatus");
Toast.makeText(getActivity(), ""+status, Toast.LENGTH_SHORT).show();
if(actionstatus.equals("Success"))
{
// Intent i = new Intent(SignActivity.this, LoginActivity.class);
// startActivity(i);
// finish();
}*/
dismissProgress();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getActivity(), "Error."+error.toString(), Toast.LENGTH_SHORT).show();
Log.d("response",""+error.toString());
dismissProgress();
}
}) {
/* #Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded; charset=UTF-8";
}*/
public String getBodyContentType()
{
return "application/json; charset=utf-8";
}
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
JSONArray jsArray = new JSONArray(listoftags);
params.put("SessionID", SessionID);
params.put("CustomerID", CustomerID);
params.put("ServiceState", ServiceState);
params.put("ServiceID", ServiceID);
params.put("Address", Address);
params.put("PaymentMode",PaymentMode);
params.put("CustomerComments",CustomerComments);
params.put("Items",jsArray.toString());
return params;
}
};
AppSingleton.getInstance(getActivity().getApplicationContext())
.addToRequestQueue(request, REQUEST_TAG);
}
but it getting error to me I want to send it like
// server side //
{
"SessionID":"9lm5255sg0ti9",
"CustomerID":"9",
"ServiceState":"Karnataka",
"ServiceID":"3",
"Address":"sfaff",
"PaymentMode":"cash",
"CustomerComments":"this is fine",
"Items":[
{
"ItemId":1,
"Cost":6777,
"Quantity":33333
}
]
}
How can send arraylist, with other strings, as raw data using volley on server.

JsonObjectRequest can be used to execute rest api using json as input.
JsonObject jobj = new JsonObject();
jobj.put("key","value");
jobj.put("key","value");
jobj.put("key","value");
jobj.put("key","value");
JsonObjectRequest request = new JsonObjectRequest(requestURL, jobj, new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response) {
}
}, new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
}
});
*Now add this request in request queue of volley.*
Here jobj is containing input parameters. It can contain even json array inside a JsonObject. Let me know in case of any query.

Rather then volley try retrofit. Make pojo model of your object you want to send, you can make that from pojo classes from https://www.jsonschema2pojo.org the send the whole object on restapi

// try the request //
try {
REQUEST QUEUE
RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
String URL = url;
JSONObject jsonBody = new JSONObject();
JSONObject jsonObject = new JSONObject();
JSONArray jsonArray = new JSONArray();
Iterator itr = listoftags.iterator();
while(itr.hasNext()){
AddRowItem ad=(AddRowItem)itr.next();
jsonObject.put("ItemId:",1);
jsonObject.put("Cost:",ad.getPrices());
jsonObject.put("Quantity:",ad.getQty());
// Log.d("ItemId:",""+1+" "+"Cost:"+ad.getPrices()+" "+"Quantity:"+ad.getQty());
}
jsonArray.put(jsonObject);
JSON VALUES PUT
jsonBody.put("SessionID", "9kp0851kh6mk3");
jsonBody.put("CustomerID", "9");
jsonBody.put("ServiceState", "Karnataka");
jsonBody.put("ServiceID", "3");
jsonBody.put("Address", "Address Demo");
jsonBody.put("PaymentMode", "cost");
jsonBody.put("CustomerComments", "Android Volley Demo");
jsonBody.put("Items", jsonArray);
final String requestBody = jsonBody.toString();
Log.d("string ---- >",""+requestBody);
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("VOLLEY", response);
showToast("get value"+response.toString());
try {
JSONObject jObj = new JSONObject(response);
String action = jObj.get("ActionStatus").toString();
String status = jObj.getString("StatusMessage");
{"ActionStatus":"Success","StatusMessage":"Order Created","RefIDName":"OrderID","RefIDValue":19}
showToast("get value"+action);
}
catch (JSONException e)
{
showToast("get error"+e.toString());
Log.d("errorissue",""+e.toString());
}
dismissProgress();
}
}, new Response.ErrorListener() {
// error response //
public void onErrorResponse(VolleyError error) {
Log.e("VOLLEY", error.toString());
showToast("get error"+error.toString());
dismissProgress();
}
}) {
#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;
}
}
};
requestQueue.add(stringRequest);
} catch (JSONException e) {
e.printStackTrace();

How to send a POST request with JSON body using Volley?

How to pass these parameter into POST method using Volley library.
API link: http://api.wego.com/flights/api/k/2/searches?api_key=12345&ts_code=123
Screenshot of JSON structure
I tried this but again facing error.
StringEntity params= new StringEntity ("{\"trip\":\"[\"{\"departure_code\":\","
+departure,"arrival_code\":\"+"+arrival+","+"outbound_date\":\","
+outbound,"inbound_date\":\","+inbound+"}\"]\"}");
request.addHeader("content-type", "application/json");
request.addHeader("Accept","application/json");
Please visit here for the details of API.

Usual way is to use a HashMap with Key-value pair as request parameters with Volley
Similar to the below example, you need to customize for your specific requirement.
Option 1:
final String URL = "URL";
// Post params to be sent to the server
HashMap<String, String> params = new HashMap<String, String>();
params.put("token", "token_value");
params.put("login_id", "login_id_value");
params.put("UN", "username");
params.put("PW", "password");
JsonObjectRequest request_json = new JsonObjectRequest(URL, new JSONObject(params),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
//Process os success response
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.e("Error: ", error.getMessage());
}
});
// add the request object to the queue to be executed
ApplicationController.getInstance().addToRequestQueue(request_json);
NOTE: A HashMap can have custom objects as value
Option 2:
Directly using JSON in request body
try {
RequestQueue requestQueue = Volley.newRequestQueue(this);
String URL = "http://...";
JSONObject jsonBody = new JSONObject();
jsonBody.put("firstkey", "firstvalue");
jsonBody.put("secondkey", "secondobject");
final String mRequestBody = jsonBody.toString();
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("LOG_VOLLEY", response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("LOG_VOLLEY", error.toString());
}
}) {
#Override
public String getBodyContentType() {
return "application/json; charset=utf-8";
}
#Override
public byte[] getBody() throws AuthFailureError {
try {
return mRequestBody == null ? null : mRequestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", mRequestBody, "utf-8");
return null;
}
}
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String responseString = "";
if (response != null) {
responseString = String.valueOf(response.statusCode);
}
return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
}
};
requestQueue.add(stringRequest);
} catch (JSONException e) {
e.printStackTrace();
}

this is an example uses StringRequest
StringRequest stringRequest = new StringRequest(Method.POST, url, listener, errorListener) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> map = new HashMap<String, String>();
map.put("api_key", "12345");
map.put("ts_code", "12345");
return map;
}
};

OkHttpClient okHttpClient = new OkHttpClient();
ContentValues values = new ContentValues();
values.put(parameter1Name, parameter1Value);
values.put(parameter2Name, parameter2Value);
RequestBody requestBody = null;
if (values != null && values.size() > 0) {
FormEncodingBuilder formEncoding = new FormEncodingBuilder();
Set<String> keySet = values.keySet();
for (String key : keySet) {
try {
values.getAsString(key);
formEncoding.add(key, values.getAsString(key));
} catch (Exception ex) {
Logger.log(Logger.LEVEL_ERROR, CLASS_NAME, "getRequestBodyFromParameters", "Error while adding Post parameter. Skipping this parameter." + ex.getLocalizedMessage());
}
}
requestBody = formEncoding.build();
}
String URL = "http://example.com";
Request.Builder builder = new Request.Builder();
builder.url(URL);
builder.post(requestBody);
Request request = builder.build();
Response response = okHttpClient.newCall(request).execute();

Android Volley onResponse get data

In a string post request for logging in. in onResponse all i am returned is the status code of 200. I would like to get the data returned as well. I am not sure where to go from this point forward? Any ideas on how to get the data returned, and not just the status code?
public void requestWithSomeHttpHeaders() {
try {
RequestQueue requestQueue = Volley.newRequestQueue(this);
String URL = "http://......";
JSONObject jsonBody = new JSONObject();
jsonBody.put("username", "yourusername");
jsonBody.put("password", "yourpassword");
final String mRequestBody = 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 mRequestBody == null ? null : mRequestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", mRequestBody, "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
System.out.println(responseString);
}
return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
}
};
requestQueue.add(stringRequest);
} catch (JSONException e) {
e.printStackTrace();
}
}

Preferably, define a method.
private void doLogin() {
// TODO: startActivity?
}
Then call that
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("VOLLEY", response);
doLogin();
}
If you want the data from the server, that is what String response is. Check your Logcat.
As mentioned in the comments, using StringRequest without implementing getBody, parseNetworkResponse, and getBodyContentType might work better.

If you want to parse JSON add method like this
public Profile getUserProfile(String response){
Profile profile = null;
try {
profile = new Profile();
JSONObject jsonObject = new JSONObject(response);
profile.setId(jsonObject.getInt(context.getString(R.string.profile_id)));
profile.setLastName(jsonObject.getString(context.getString(R.string.profile_lastName)));
profile.setName(jsonObject.getString(context.getString(R.string.profile_name)));
profile.setEmail(jsonObject.getString(context.getString(R.string.profile_email)));
} catch (JSONException | NullPointerException e) {
e.printStackTrace();
return null;
}
return profile;
}
In your onResponse method
#Override
public void onResponse(String response) {
//If you have son object
Profile profile = getUserProfile(response)
}
