Am trying to send String and int as params in volley. But it show error on String if i use Map<String,Integer> params = new HashMap<String, String>(); and show error on int if i use Map<String,String> params = new HashMap<String, String>(); So how can i send int and String as a param in post request.
StringRequest stringRequest = new StringRequest(Request.Method.POST, "http://www.aaa.com/insert/signup" ,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("sign_up_res", response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("error" , error.toString());
}
}){
#Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put("firstname" , PreferenceManager.getDefaultSharedPreferences(getApplicationContext()).getString(Local_Preference.FIRSTNAME, "Not Set") );
params.put("number" , "123");
return params;
}
};
stringRequest.setRetryPolicy(new DefaultRetryPolicy(
1000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
RequestQueue requestQueue = Volley.newRequestQueue(SignUp2Activity.this);
requestQueue.add(stringRequest);
In Sql table is like firstname (varchar) and number(int). I don't want to change the int type to varchar in sql. Is there any way to send int and String in a single params.
you can do this create a
Map params = new HashMap();
then
params.put(key,value); // for string
params.put(key,String.valueOf(value)); // for int As suggested
Please follow the code using this my problem is solved
String tag_json_obj = "json_obj_req";
String url = "https://api.androidhive.info/volley/person_object.json";
ProgressDialog pDialog = new ProgressDialog(this);
pDialog.setMessage("Loading...");
pDialog.show();
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
pDialog.hide();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
pDialog.hide();
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("name", "Androidhive");
params.put("email", "abc#androidhive.info");
params.put("password", "password123");
return params;
}
};
// Adding request to request queue
AppController.getInstance().addToRequestQueue(jsonObjReq, tag_json_obj);

I am a complete noob to Android Studio, Java and Stack Overflow. My app performs a lot of HTTP Post requests using Volley and hence I've made an independent Java class with the code to perform the post request.
public class HTTPReq {
String[] finalResponse = new String[1];
public String postRequest(final HashMap<String,String> params, final Context context) {
RequestQueue requestQueue = Volley.newRequestQueue(context);
String url = "https://reqres.in/api/login";
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
finalResponse[0] = response;
Toast.makeText(context, "2" + finalResponse[0], Toast.LENGTH_LONG).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
finalResponse[1] = error.getMessage();
//Toast.makeText(context, "Response Failed", Toast.LENGTH_LONG).show();
}
}) {
#Override
protected Map<String, String> getParams() {
return params;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/x-www-form-urlencoded");
return params;
}
};
requestQueue.add(stringRequest);
Toast.makeText(context, "3" + finalResponse[0], Toast.LENGTH_LONG).show();
return finalResponse[0];
}
}
What I'm trying to achieve is to get the response of the http request to the function call using return.
The function call is as follows:
public void login(String phno, String password,Context context)
{
HashMap<String,String> credentials = new HashMap<String, String>();
credentials.put("email","eve.holt#reqres.in");
credentials.put("password","cityslicka");
HTTPReq httpReq = new HTTPReq();
String response = httpReq.postRequest(credentials,context);
Toast.makeText(context, "1" + response, Toast.LENGTH_LONG).show();
}
I hope it's clear what I'm trying to achieve. Please help me with this.
your con use feature interface
public class HTTPReq {
public void postRequest(final HashMap<String, String> params, final Context context, final ResponseCallBack callBack) {
RequestQueue requestQueue = Volley.newRequestQueue(context);
String url = "https://reqres.in/api/login";
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
callBack.onResponse(response);
Toast.makeText(context, response, Toast.LENGTH_LONG).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
callBack.onError(error);
Toast.makeText(context, "Response Failed", Toast.LENGTH_LONG).show();
}
}) {
#Override
protected Map<String, String> getParams() {
return params;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/x-www-form-urlencoded");
return params;
}
};
requestQueue.add(stringRequest);
}
}
calss interface :
import com.android.volley.VolleyError;
public interface ResponseCallBack<T> {
public void onResponse(T response);
public void onError(VolleyError error_response);
}
MainActivity:
public class MainActivity extends AppCompatActivity implements ResponseCallBack {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
HTTPReq httpReq = new HTTPReq();
HashMap<String, String> credentials = new HashMap<String, String>();
credentials.put("email", "eve.holt#reqres.in");
credentials.put("password", "cityslicka");
httpReq.postRequest(credentials, this, this);
}
#Override
public void onResponse(Object response) {
Log.e("TAG", "onResponse: " + response);
}
#Override
public void onError(VolleyError error_response) {
Log.e("TAG", "onError: " + error_response);
}
I am going to use volley to get data
RequestQueue queue = Volley.newRequestQueue(SummaryPhoneActivity.this);
String url = "https://covid19storageservice.table.core.windows.net/COVID19Survey?sv=2019-02-02&ss=bfqt&srt=sco&sp=rwdlacup&se=2020-06-30T18:04:08Z&st=2020-03-30T10:04:08Z&spr=https&sig=Ei3Kcr6xT5e7znK4ebwx6%2FVS09Ia5pbD1lnWRBh6bm4%3D";
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("response:", response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("error:", error.toString());
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/json");
return params;
}
};
queue.add(stringRequest);
I can get error: com.android.volley.ClientError.
Above url is working on postman.
How can I use volley for above case. Thanks for your advance.
I am trying to send a post request to my server
my server read Headers of the request in String Format but getHeaders() in Volley return : Map< String, String >
Is there any way to send headers of request in string Format ?!
this is my Code Request :
Map<String, String> params = new HashMap<String, String>();
params.put("MY_FIRST_DATA_KEY", "MY_FIRST_DATA_VALUE");
params.put("MY_SECOND_DATA_KEY", "MY_SECOND_DATA_VALUE");
String url = "http://MY_URL.com";
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, new JSONObject(params), new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.e(TAG, "onResponse: " + response.toString() );
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "onErrorResponse: " + error.toString() );
error.printStackTrace();
}
})
{
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
headers.put("MY_KEY","MY_VALUE");
/* HERE i need to return a String Value */
return headers;
}
};
request.setRetryPolicy(new DefaultRetryPolicy(20000 , 3 , 3));
Volley.newRequestQueue(context).add(request);
try overriding getParams()
#Override
protected Map<String,String> getParams(){
Map<String, String> params = new HashMap<String, String>();
params.put("MY_FIRST_DATA_KEY", "MY_FIRST_DATA_VALUE");
params.put("MY_SECOND_DATA_KEY", "MY_SECOND_DATA_VALUE");
return params;
}
You can add getParams() in the JsonObjectRequest()
#Override
public Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("Parameter1", "value");
params.put("Parameter2", "value");
return params;
}
Hope it helps.
This is how I made a volley POST request adding headers and body
private void call_api(final String url){
if(!this.isFinishing() && getApplicationContext() != null){
new Handler(Looper.getMainLooper()).post(new Runnable() {
#Override
public void run() {
resultsTextView.setVisibility(View.INVISIBLE);
loader.setVisibility(View.VISIBLE);
}
});
Log.e("APICALL", "\n token: " + url);
StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.e("APICALL", "\n response: " + response);
if(!FinalActivity.this.isFinishing()){
try {
JSONObject response_json_object = new JSONObject(response);
JSONArray linkupsSuggestionsArray = response_json_object.getJSONObject("data").getJSONArray("package");
final JSONObject k = linkupsSuggestionsArray.getJSONObject(0);
final String result = k.getJSONArray("action").getJSONObject(0).getString("url");
last_results = result;
last_results_type = k.getString("type");
new Handler(Looper.getMainLooper()).post(new Runnable() {
#Override
public void run() {
loader.setVisibility(View.INVISIBLE);
resultsTextView.setText(result);
resultsTextView.setVisibility(View.VISIBLE);
}
});
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(), "An unexpected error occurred.", Toast.LENGTH_LONG).show();
finish();
}
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("APICALL", "\n error: " + error.getMessage());
Toast.makeText(getApplicationContext(), "Check your internet connection and try again", Toast.LENGTH_LONG).show();
finish();
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
headers.put("apiUser", "user");
headers.put("apiKey", "key");
headers.put("Accept", "application/json");
//headers.put("Contenttype", "application/json");
return headers;
}
#Override
protected Map<String, String> getParams() {
Map<String, String> map = new HashMap<>();
map.put("location", "10.12 12.32");
return map;
}
};
stringRequest.setShouldCache(false);
stringRequest.setRetryPolicy(new DefaultRetryPolicy(
DefaultRetryPolicy.DEFAULT_TIMEOUT_MS * 2,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
requestQueue.add(stringRequest);
}
}
When i call URL on postman, it returns expected result. I use PUT method using Volley, but it does not work.
StringRequest reg=new StringRequest(Request.Method.PUT, AppConfig.Registration, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("USER_REG",response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("USER_REG","-------------"+error);
}
}){
#Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put(name1,Name);
params.put(client_id1,CID);
params.put(email1,Email);
params.put(mobile1,Mobile);
params.put(password1,Password);
params.put(device_id1,"123456");
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(reg);
Here's the postman output.
Currently you are sending the data from your Android using Volley as path parameters which should be sent as JSON like the following.
RequestQueue queue = Volley.newRequestQueue(this);
private void makeJsonObjReq() {
Map<String, String> postParam= new HashMap<String, String>();
postParam.put(name1,Name);
postParam.put(client_id1,CID);
postParam.put(email1,Email);
postParam.put(mobile1,Mobile);
postParam.put(password1,Password);
postParam.put(device_id1,"123456");
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.PUT,
Const.YOUR_URL, new JSONObject(postParam),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
msgResponse.setText(response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
}) {
#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);
You need to add the Content-Type as application/json in the header as well.
This is my code for JsonArrayRequest I think either it is incomplete or incorrect. The problem is nothing getting added into the database and I am not getting any errors. I am new to programming so I have no idea as to where I might be going wrong.
private void insertToDb() {
JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.POST, INVEST_URL,
itemSelectedJson, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Toast.makeText(AddInvEst.this, "The echoed response is "+response, Toast.LENGTH_SHORT).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> headers = new HashMap<String, String>();
headers.put("Content-Type","application/json");
headers.put("Accept", "application/json");
return headers;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(jsonArrayRequest);
}
This is code for creating a jsonArray
private void selectedItems() {
billType = (invEstSwitch.isChecked() ? textViewEstimate : textViewInvoice)
.getText().toString();
itemselected.put("custInfo", custSelected.toString());
itemselected.put("invoiceNo", textViewInvNo.getText().toString());
itemselected.put("barcode", barCode.getText().toString());
itemselected.put("desc", itemDesc.getText().toString());
itemselected.put("weight", weightLine.getText().toString());
itemselected.put("rate", rateAmount.getText().toString());
itemselected.put("makingAmt", makingAmount.getText().toString());
itemselected.put("net_rate", netRate.getText().toString());
itemselected.put("itemTotal", itemtotal.getText().toString());
itemselected.put("vat", textViewVat.getText().toString());
itemselected.put("sum_total", textViewSum.getText().toString());
itemselected.put("bill_type", billType);
itemselected.put("date", textViewCurrentDate.getText().toString());
//Add the map to the Array
itemSelectedJson.put(itemselected);
index++;
}
And this is my php code.
<?php
require "init.php";
$json = file_get_contents('php://input');
//$data = json_decode($json,true);
// remove the ,true so the data is not all converted to arrays
$data = json_decode($json);
// Now process the array of objects
foreach ( $data as $inv ) {
$custInfo = $inv->custInfo;
$rate = $inv->rate;
$weight= $inv->weight;
$desc= $inv->desc;
$makingAmt= $inv->makingAmt;
$vat= $inv->vat;
$itemTotal= $inv->itemTotal;
$sum_total= $inv->sum_total;
$barcode= $inv->barcode;
$net_rate= $inv->net_rate;
$date= $inv->date;
$invoiceNo= $inv->invoiceNo;
$bill_type= $inv->bill_type;
$sql = "INSERT INTO selected_items
(custInfo, invoiceNo, barcode, desc,
weight, rate, makingAmt,net_rate,
itemTotal,vat,sum_total,bill_type,date)
VALUES
('$custInfo','$invoiceNo','$barcode','$desc',
'$weight','$rate','$makingAmt','$net_rate',
'$itemTotal','$vat','$sum_total','$bill_type','$date')";
$res = mysql_query($sql,$con);
if(!$res){
$result = new stdClass();
$result->status = false;
$result->msg = mysql_error();
echo json_encode($result);
exit;
}
}
?>
You missed to add a method getParams() inside the post request, it should have this structure
StringRequest stringRequest = new StringRequest(Request.Method.POST, "url",
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
errorHandler(error);
}
}){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String,String> params = new HashMap<>();
//Adding parameters to request
params.put("KEY1", key1);
params.put("KEY2", key2);
//returning parameter
return params;
}
};
//Adding the string request to the queue
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
