Code as below:
public void loginPost(String url, String emailAddress, String password){
Map<String, String> params = new HashMap();
params.put("email", emailAddress);
params.put("password", password);
JSONObject parameters = new JSONObject(params);
String LOGIN_REQUEST_TAG = "LOGIN_REQUEST_TAG";
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, parameters, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("Login Response:", response.toString());
JSONObject responseOject = response;
if(responseOject.has("data")){
try {
Log.d("Data Response", responseOject.getString("data"));
} catch (JSONException e) {
e.printStackTrace();
}
}else if(responseOject.has("error")){
try {
errorMessage = responseOject.getString("error");
new AlertDialog.Builder(MainActivity.this)
.setTitle("Error")
.setMessage(errorMessage)
.setNegativeButton("OK", null)
.show();
} catch (JSONException e) {
e.printStackTrace();
}
}else{
//Server error. Come back again later
Log.d("Server error", "Server Error");
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.e("Error at login: ", error.getMessage());
}
});
AppSingleton.getInstance(getApplicationContext()).addToRequestQueue(jsonObjectRequest,LOGIN_REQUEST_TAG);
}
All the parameters and URL are correct as I have checked it during debug. And everything works fine in Postman as well. However, the code above just wont go into onResponse method and I am not receiving any error. But it is giving a warning that "responseOject" is redundant. Am I doing it wrongly? Quite new to Android development.
Error:
BasicNetwork.performRequest: Unexpected response code 401
It is a POST API and I am using Request.Method.Post, why am I receiving that error?
Before using the API test it in Postman. You will get a clear view of what is happening.
The error code 401 means you parameters are wrong. OR you are unauthorized to access that API.
Try this code for this type of call.
private void callNetwork(final String email, final String password) {
String json_object_request = "jsonObjectRequest";
//Creating a string request
StringRequest stringRequest = new StringRequest(Request.Method.POST, Config.URL_LOGIN,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if (response != null) {
parseData(response);
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
progressBar.setVisibility(View.GONE);
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<>();
//Adding parameters to request
params.put("email", email);
params.put("password", password);
//returning parameter
return params;
}
};
//Adding the string request to the queue
AppController.getInstance().addToRequestQueue(stringRequest, json_object_request);
}
This is my volley multipart request. But request parameters are received empty in the backend. I am not sure where the error is in front-end or backend. So for ensuring I want to print the request, I am sending in the Log.

You can just write this code before your adding the request to the queue:
VolleyLog.DEBUG = true;
Don't forget to remove this line after you are done debugging.
I am developing an app in which i find the origin and destination of a car and send it to a server.
I know how to use volley to send an string however i am finding it hard to send data in JSON format.
Part of the code is given below:

Having trouble on VolleyRequest getting always error response when loading it onCreate. I want to do is when the fragment loads. but when I try it, the Logcat gives me an error 400. on this Java class, i have another function that has sending data to API. I just copied my code :). here is the code that getting a error response.
String url = "MYLINK.com";
try {
RequestQueue queue = Volley.newRequestQueue(getActivity());
StringRequest postRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Toast.makeText(getContext(), "Successful send pending data", Toast.LENGTH_SHORT).show();
String qu = ("update tickets set is_send = '1' where ticket_tick_no = '" + ticket_tick_no_delayed + "'");
sqldb.execSQL(qu);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getContext(), "Error Response here", Toast.LENGTH_SHORT).show();
Log.e("------", String.valueOf(error.networkResponse.statusCode));
}
}
) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("control_no", trip_no_delayed);

};
queue.add(postRequest);
} catch (Exception e) {

}
I am trying to send POST parameters in a Volley JsonObjectRequest. Initially, it was working for me by following what the official code says to do of passing a JSONObject containing the parameters in the constructor of the JsonObjectRequest. Then all of a sudden it stopped working and I haven't made any changes to the code that was previously working. The server no longer recognizes that any POST parameters are being sent. Here is my code:
RequestQueue queue = Volley.newRequestQueue(this);
String url ="http://myserveraddress";
// POST parameters
Map<String, String> params = new HashMap<String, String>();
params.put("tag", "test");
JSONObject jsonObj = new JSONObject(params);
// Request a json response from the provided URL
JsonObjectRequest jsonObjRequest = new JsonObjectRequest
(Request.Method.POST, url, jsonObj, new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response)
{
Toast.makeText(getApplicationContext(), response.toString(), Toast.LENGTH_SHORT).show();
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error)
{
Toast.makeText(getApplicationContext(), error.toString(), Toast.LENGTH_SHORT).show();
}
});
// Add the request to the RequestQueue.
queue.add(jsonObjRequest);
Here is the simple tester PHP code on the server:
$response = array("tag" => $_POST["tag"]);
echo json_encode($response);
The response I get is {"tag":null}
Yesterday, it worked fine and was responding with {"tag":"test"}
I haven't changed a single thing, but today it is no longer working.
In the Volley source code constructor javadoc it says that you can pass a JSONObject in the constructor to send post parameters at "#param jsonRequest":
https://android.googlesource.com/platform/frameworks/volley/+/master/src/main/java/com/android/volley/toolbox/JsonObjectRequest.java
/**
* Creates a new request.
* #param method the HTTP method to use
* #param url URL to fetch the JSON from
* #param jsonRequest A {#link JSONObject} to post with the request. Null is allowed and
* indicates no parameters will be posted along with request.
I have read other posts with similar questions, but the solutions haven't worked for me:
Volley JsonObjectRequest Post request not working
Volley Post JsonObjectRequest ignoring parameters while using getHeader and getParams
Volley not sending a post request with parameters.
I've tried setting the JSONObject in the JsonObjectRequest constructor to null, then overriding and setting the parameters in the "getParams()", "getBody()", and "getPostParams()" methods, but none of those overrides has worked for me. Another suggestion was to use an additional helper class that basically creates a custom request, but that fix is a bit too complex for my needs. If it comes down to it I will do anything to make it work, but I am hoping that there is a simple reason as to why my code was working, and then just stopped, and also a simple solution.
You just have to make a JSONObject from your HashMap of parameters:
String url = "https://www.youraddress.com/";
Map<String, String> params = new HashMap();
params.put("first_param", 1);
params.put("second_param", 2);
JSONObject parameters = new JSONObject(params);
JsonObjectRequest jsonRequest = new JsonObjectRequest(Request.Method.POST, url, parameters, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
//TODO: handle success
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
//TODO: handle failure
}
});
Volley.newRequestQueue(this).add(jsonRequest);
I ended up using Volley's StringRequest instead, because I was using too much valuable time trying to make JsonObjectRequest work.
RequestQueue queue = Volley.newRequestQueue(this);
String url ="http://myserveraddress";
StringRequest strRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response)
{
Toast.makeText(getApplicationContext(), response, Toast.LENGTH_SHORT).show();
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error)
{
Toast.makeText(getApplicationContext(), error.toString(), Toast.LENGTH_SHORT).show();
}
})
{
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String>();
params.put("tag", "test");
return params;
}
};
queue.add(strRequest);
This worked for me. Its just as simple as JsonObjectRequest, but uses a String instead.
I had a similar problem, but I found out that the problem was not on the client side, but in the server side. When you send a JsonObject, you need to get the POST object like this (in the server side):
In PHP:
$json = json_decode(file_get_contents('php://input'), true);
You can use StringRequest to do the same things you can wtih JsonObjectRequest, while still beeing able to easily send POST parameters. The only thing you have to do is to create a JsonObject out of the request String you get, and from there you can continue as if it were JsonObjectRequest.
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
//Creating JsonObject from response String
JSONObject jsonObject= new JSONObject(response.toString());
//extracting json array from response string
JSONArray jsonArray = jsonObject.getJSONArray("arrname");
JSONObject jsonRow = jsonArray.getJSONObject(0);
//get value from jsonRow
String resultStr = jsonRow.getString("result");
} catch (JSONException e) {
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String,String> parameters = new HashMap<String,String>();
parameters.put("parameter",param);
return parameters;
}
};
requestQueue.add(stringRequest);
Use CustomJsonObjectRequest helper class mentioned here.
and implement like this -
CustomJsonObjectRequest request = new CustomJsonObjectRequest(Method.POST, URL, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Toast.makeText(getActivity(), response.toString(), Toast.LENGTH_SHORT).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getActivity(), "Error.", Toast.LENGTH_SHORT).show();
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("id", id);
params.put("password", password);
return params;
}
};
VolleySingleton.getInstance().addToRequestQueue(request);
Using the JSONObject object to send parameters means the parameters will be in JSON format in the HTTP POST request body :
Map<String, String> params = new HashMap<String, String>();
params.put("tag", "test");
params.put("tag2", "test2");
JSONObject jsonObj = new JSONObject(params);
Will create this JSON object and insert it into the body of the HTTP POST request:
{"tag":"test","tag2":"test2"}
Then the server must decode the JSON to understand these POST parameters.
But normally HTTP POST paramaters are write in the body like:
tag=test&tag2=test2
But NOW here the question is why Volley is set in this manner?
A server reading a HTTP POST method should by standard always try to read parameters also in JSON (other than in plain text) and so a server that does not accomplish is a bad server?
Or instead a HTTP POST body with parameters in JSON is not what normally a server want?
Might help someone and save you some time thinking.
I had a similar issue, the server code was looking for the Content-Type header. It was doing it this way:
if($request->headers->content_type == 'application/json' ){ //Parse JSON... }
But Volley was sending the header like this:
'application/json; charset?utf-8'
Changing the server code to this did the trick:
if( strpos($request->headers->content_type, 'application/json') ){ //Parse JSON...
I had similar problem. But I found out that the problem was not on the server side, but the problem is about cache. You have to clear your RequestQueue Cache.
RequestQueue requestQueue1 = Volley.newRequestQueue(context);
requestQueue1.getCache().clear();
You can do it this way:
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(SignActivity.this, ""+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(SignActivity.this, "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";
}
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Email", emailval);
params.put("PassWord", passwordval);
params.put("FirstName", firstnameval);
params.put("LastName", lastnameval);
params.put("Phone", phoneval);
return params;
}
};
AppSingleton.getInstance(SignActivity.this.getApplicationContext()).addToRequestQueue(request, REQUEST_TAG);

// response will be a json object
String userbalance = response.getString("userbalance");
Log.d("userbalance",userbalance);
String walletbalance = response.getString("walletbalance");
Log.d("walletbalance",walletbalance);
} catch (JSONException e) {

Hope am not too late to the party:
The issue is from the server side. If you are using PHP add the following lines at the top of your php api file (after includes)
$inputJSON = file_get_contents('php://input');
if(get_magic_quotes_gpc())
{
$param = stripslashes($inputJSON);
}
else
{
$param = $inputJSON;
}
$input = json_decode($param, TRUE);
Then to retrieve your values
$tag= $input['tag'];
Use GET in place of POST for using JsonObjectRequest
VolleySingleton.getInstance()
.add(new StringRequest(Request.Method.POST, urlToTest, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// do stuff...
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// exception
}
}) {
#Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded; charset=UTF-8";
}
#Override
protected Map<String, String> getParams() {
return ServerApi.getRequiredParamsRequest(context);
}
}
);
...Initially, it was working for me
....Then all of a sudden it stopped working and I haven't made any changes to
the code
if you haven't made any changes to a previously working code then I suggest checking other parameters such as URL , as the IP address may change if you are using your own Computer as a server!
