I am trying to send data to my server. I create a JsonObject and I pass it as a parameter when creating the JsonObjectRequest. It doesn't give any error, but it is not returning anything. Tried with postman and it is working fine.
This is my code:
JSONObject jsonBody = new JSONObject();
try {
jsonBody.put("firstname", "asd");
jsonBody.put("lastname", "asd");
jsonBody.put("id", "1");
} catch (JSONException e) {
e.printStackTrace();
}
//creating a JsonObjectRequest
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, showPlayersUrl,
jsonBody, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
JSONArray players;
try{
players = response.getJSONArray("Players");
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
requestQueue.add(jsonObjectRequest);
}
Ok, found the problem. Server side i wasn't accepting the data as json format. Just had to add this and it works:
$_POST = json_decode(file_get_contents('php://input'), true);
Try it:
RequestQueue queue = Volley.newRequestQueue(this);
private void makeJsonObjReq() {
showProgressDialog();
Map<String, String> postParam= new HashMap<String, String>();
postParam.put("un", "xyz#gmail.com");
postParam.put("p", "somepasswordhere");
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
Const.URL_LOGIN, new JSONObject(postParam),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
msgResponse.setText(response.toString());
hideProgressDialog();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hideProgressDialog();
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
};
jsonObjReq.setTag(TAG);
queue.add(jsonObjReq);
}

Hi I am using volley as JSON Parsing. I am using POST method and sending parameters in post request. I am getting following error when parsing the data, I am getting following error. I want to use volley. I have tried with JsonArrayRequest but it does not allow to send parameters as JSONObject,which I am using in my code.
org.json.JSONArray cannot be converted to JSONObject
Request is like
{
"city":"acd",
"user_id":"82",
"phone_number1":"1232131231",
"my_type":"asf"
}
Response is like
[{
"name":"dfdfd",
}]
Following is my code
private void Search_Refer() {
//initialize the progress dialog and show it
progressDialog = new ProgressDialog(SearchReferNameActivity.this);
progressDialog.setMessage("Please wait....");
progressDialog.show();
try {
JSONObject jsonBody = new JSONObject();
jsonBody.put("city", "acb");
jsonBody.put("user_id", "82");
jsonBody.put("phone_number1", "12332123231");
jsonBody.put("my_type", "asf");
JsonObjectRequest jsonOblect = new JsonObjectRequest(Request.Method.POST, Constants.BASE_URL1+"api/lab/search", jsonBody, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Toast.makeText(getApplicationContext(), response.toString(), Toast.LENGTH_LONG).show();
Log.e("Search EROOR", response.toString());
try {
JSONArray itemArray=new JSONArray(response);
dataModelArrayList = new ArrayList<>();
for (int i = 0; i < itemArray.length(); i++) {
SearchModel playerModel = new SearchModel();
JSONObject dataobj = itemArray.getJSONObject(i);
//playerModel.setProduct_name(dataobj.getString("name"));
playerModel.setRadiology_store_first_name(dataobj.getString("radiology_store_first_name"));
dataModelArrayList.add(playerModel);
}
} catch (JSONException e) {
e.printStackTrace();
}
progressDialog.dismiss();
/* Intent intent = new Intent(SearchReferNameActivity.this, SearchResult.class);
intent.putExtra("Search_result", dataModelArrayList);
startActivity(intent);*/
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(), "Response: " + error.toString(), Toast.LENGTH_SHORT).show();
System.out.println("Search Eroor"+error.toString());
progressDialog.dismiss();
}
}){
#Override
public String getBodyContentType() {
return "application/json";
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Authorization", "Bearer "+deviceToken);
return headers;
}
};
jsonOblect.setRetryPolicy(new DefaultRetryPolicy(
10000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
MyApplication.getInstance().addToRequestQueue(jsonOblect,"postrequest");
} catch (JSONException e) {
e.printStackTrace();
}
// Toast.makeText(getApplicationContext(), "done", Toast.LENGTH_LONG).show();
}
Use JsonArrayRequest or StringRequest in place of JsonObjectRequest
JsonArrayRequest
change the following response parameter to JSONArray
Instead of new Response.Listener<JSONObject> Use new Response.Listener<JSONArray>
// JSONArray insated of JSONObject
public void onResponse(JSONArray response) {
}
Use Below code
StringRequest stringRequest = new StringRequest(Request.Method.POST, "api/lab/search", new Response.Listener<String>() {
#Override
public void onResponse(String response) {
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("city", "abcd");
params.put("user_id", "82");
params.put("phone_number1", "01235467895");
params.put("my_type", "asf");
return params;
}
};
I am using post method in volley. I searched and found that getHeader() is used to send header in request.The solution was to use JSONObject request instead of string request(which i am using currently) but is there a way of sending header through this method? Because in that case I will have to modify a lot of code in many classes. Sorry for the English, I am not a native speaker.
The request parameter is a json object. I am sending the parameters using following code.
mRequestQueue = Volley.newRequestQueue(getContext());
mStringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("Response", "onResponse: " + response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.i("This is the error", "Error :" + error.toString());
}
})
{
#Override
public String getBodyContentType() {
return "application/json";
}
#Override
public byte[] getBody() throws AuthFailureError {
HashMap<String, String> params2 = new HashMap<String, String>();
params2.put("AssigneeId",userid);
params2.put("IssueStatus", "5");
return new JSONObject(params2).toString().getBytes();
}
};
mRequestQueue.add(mStringRequest);
This request also has StringRequest. Please use the getHeaders() in this way:
public void requestWithSomeHttpHeaders() {
RequestQueue queue = Volley.newRequestQueue(this);
String url = "http://www.somewebsite.com";
StringRequest getRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response) {
// response
Log.d("Response", response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
// TODO Auto-generated method stub
Log.d("ERROR","error => "+error.toString());
}
}
) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("User-Agent", "Nintendo Gameboy");
params.put("Accept-Language", "fr");
return params;
}
};
queue.add(getRequest);
}
For JsonObjectRequest:
JsonObjectRequest req = new JsonObjectRequest(Request.Method.GET,url,
null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(tag, response.toString());
activity.hideDialog();
try {
activity.onRequestServed(response, code);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(tag, "Error: " + error.getMessage());
Log.e(tag, "Site Info Error: " + error.getMessage());
Toast.makeText(activity.getApplicationContext(),
error.getMessage(), Toast.LENGTH_SHORT).show();
activity.hideDialog();
try {
activity.onRequestServed(null,code);
} catch (JSONException e) {
e.printStackTrace();
}
}
}) {
/**
* Passing some request headers
*/
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
//headers.put("Content-Type", "application/json");
headers.put("key", "Value");
return headers;
}
};
I'm New to android Volley. I accessing a API server and its response is JSON.
The response JSON is like this\
{
status:true,
data : [{
id:1,
name:'name 1',
},
{
id:2,
name:'name 2 ',
}]
}
I tried using JsonObjectRequest & JsonArrayRequest in Volley. Both throws error. What is the Right request type to use and How to parse it?
You will need to use a JsonObjectRequest for this, if it is a post request use the following
try{
JSONObject jsonBody = new JSONObject("add json body to post");
RequestQueue mQueue = Volley.newRequestQueue(getApplicationContext());
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(LookUp.url, jsonBody,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// pDialog.cancel();
try{
if(response.getString("status").equals("true")){
JSONArray jsonArray=response.getJSONArray("data");
for(int i=0;i<jsonArray.length();i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String name=jsonObject.getString("name");
}
}
}
catch (JSONException error){
Log.e("TAGJE", error.getMessage());
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("TAGE", error.getMessage(), error);
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("Content-Type", "application/json");
return params;
}
};
mQueue.add(jsonObjectRequest);
}
catch (JSONException ex){
ex.printStackTrace();
}
and for a get request follow this
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.GET,
url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
try{
if(response.getString("status").equals("true")){
JSONArray jsonArray=response.getJSONArray("data");
for(int i=0;i<jsonArray.length();i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String name=jsonObject.getString("name");
}
}
}
catch (JSONException error){
Log.e("TAGJE", error.getMessage());
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
});
This is JsonObjectRequest and I am getting the error. Help me out......
Map<String, String> jsonParams = new HashMap<String, String>();
jsonParams.put("email",email.getText().toString());
JsonObjectRequest jsonObjectRequest=new JsonObjectRequest(Request.Method.POST, json_url, new JSONObject(jsonParams), new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
Log.d("Response", response.toString());
name.setText(response.getString("Name"));
mobile.setText(response.getString("Mobile"));
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError{
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
};
MySingleton.getInstance(getApplicationContext()).addToRequestQueue(jsonObjectRequest);
Try using volley StringRequest, it seems, server is sending you Strings instead of JsonOBJECTS. If JsonObject is what you need, you must do some changes on the server side. If not try this:
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
StringRequest request = new StringRequest(Request.Method.POST,
Addresses.LOGIN_URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response);
Log.d("Response", jsonObject .toString());
name.setText(jsonObject .getString("Name"));
mobile.setText(jsonObject .getString("Mobile"));
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
};
queue.add(request);
This might be your solution if your server receives values in json form.
JSONObject jsonobject= new JSONObject();
jsonobject.put("email",email.getText().toString());
JsonObjectRequest jsonObjectRequest=new JsonObjectRequest(Request.Method.POST, json_url, jsonobject, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
Log.d("Response", response.toString());
name.setText(response.getString("Name"));
mobile.setText(response.getString("Mobile"));
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
};
MySingleton.getInstance(getApplicationContext()).addToRequestQueue(jsonObjectRequest);
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);
