How to ensure that header request are sent when using Volley

How to ensure that header request are sent when using Volley - android

I am trying to call a RESTful API in my Android app using Volley. The API requires that the user get authenticated using a public key and a hash that will be sent via the http header.
When I try to do send a POST request with the headers of the public key and the hash, I find that the header is not appended / received by the server and I get Volley error - BasicNetwork.performRequest: Unexpected response code 400
This is the method that i am trying to use to send the header request with the request parameters using JSON.
HashMap<String, String> params = new HashMap<String, String>();
params.put("email", email.getText().toString());
params.put("password", password.getText().toString());
pDialog = new ProgressDialog(LoginActivity.this);
pDialog.setMessage("Logging in...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
RequestQueue requestQueue = VolleySingleton.getInstance().getRequestQueue();
JsonObjectRequest request = new JsonObjectRequest(ApplicationConstants.url_sign_in, new JSONObject
(params), new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
Log.d(TAG, "onResponse") ;
error = response.getBoolean(TAG_ERROR);
message = response.getString(TAG_MESSAGE);
Toast.makeText(LoginActivity.this, message + " value of error", Toast.LENGTH_LONG).show();
pDialog.cancel();
} catch (JSONException e) {
e.printStackTrace();
}
Toast.makeText(LoginActivity.this, message, Toast.LENGTH_SHORT).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d(TAG,"onErrorResponse()") ;
pDialog.cancel();
NetworkResponse networkResponse = error.networkResponse;
if (networkResponse != null && networkResponse.statusCode == HttpStatus.SC_UNAUTHORIZED) {
// HTTP Status Code: 401 Unauthorized
Toast.makeText(LoginActivity.this, message, Toast.LENGTH_SHORT).show();
}
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put(ApplicationConstants.publicKey, "Yahoo");
headers.put(ApplicationConstants.hash, "Google");
Log.d(TAG,"getHeaders()") ;
return headers;
}
};
requestQueue.add(request);
ApplicationConstants class
public interface ApplicationConstants {
//String ip = "10.0.3.2";
String ip = "192.168.100.2";
String publicKey = "pskPublicKey";
String hash = "pskPublicKey";
If I try this with only the request parameters it works but when when i try to send a header request it fails to send the header request.
As you can see in the pic I supplied the public key and the hash in postman and I also sent data in the header from android but it is not being received in the server

400 means a Bad Request to the server. Maybe the headers are wrong.
You could try adding the Content-Type=application/json header as follows
header.put("Content-Type", "application/json");
If this doesn't work then you should try the request in the REST client and see if it works with the given headers. Make sure the request works fine on the rest client before trying to break your head in Android.

override your getBodyContentType method
public String getBodyContentType()
{
return "application/json";
}

Mailchimp error 400 request, can't send users to list

I'm working with Mailchimp and I want to send an email address to my list, I have done this so far with Volley:
public void suscribeMailChamp(){
String listid = "listID";
String url = "https://us16.api.mailchimp.com/3.0/lists/" + listid + "/members/";
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(this);
StringRequest sr = new StringRequest(Request.Method.POST,url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
//
Toast.makeText(MainActivity.this , "success" , Toast.LENGTH_SHORT).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this , error.toString() , Toast.LENGTH_SHORT).show();
}
}){
#Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put("email_address","testmailchimp#gmail.com");
params.put("status","unsubscribed");
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");
params.put("Authorization" , "apikey <here my api key>");
return params;
}
};
queue.add(sr);
}
but I get error 400:
Unexpected response code 400 for
https://us16.api.mailchimp.com/3.0/lists/b9a5943047/members/
Here is a link for troubleshooting but I can't get the error:
http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/

Did you check the error in the link? It says
{
"type":"http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/",
"title":"API Key Missing",
"status":401,
"detail":"Your request did not include an API key.",
"instance":"924c81cc-90e9-498d-b0fd-c7b54cba207f"
}
which means you are not (or correctly) sending the API key for mail chimp in the request. Just add the mailChimp API key in the params for Volley request
So the way you would send your API key is this
params.put("Authorization", "Basic "+Base64.encodeToString(("apikey:"+apiKey).getBytes("UTF-8"),Base64.DEFAULT))

I got stuck at this too. Mailchimp documentation is very poor.
I found the solution from github
Just send 'Authorization': 'apikey myapikey' in your header

how NOT to escape slashes, sending POST request using volley

I am sending POST request using volley. Request has custom headers and json request body. One of the json values in request body is a URL. When i create a jsonobject the // in URL is sent as \/\/. (e.g. "key1:"http//www.xyz.com" is sent as "key1":"http:\/\/www.xyz.com"
This causes a 400 error. How do i fix this?
Here is the POST using volley:
RequestQueue queue = Volley.newRequestQueue(this);
try{
jsonBody = new JSONObject();
jsonBody.put("Key1","http://xyz1.com");
jsonBody.put("Key2","val2");
}
catch (JSONException e){
}
JsonObjectRequest req = new JsonObjectRequest(Request.Method.POST,URL, jsonBody,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// handle response
Log.d("MAIN","response recd="+response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// handle error
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("CUSTOM_HEADER", "Yahoo");
headers.put("ANOTHER_CUSTOM_HEADER", "Google");
return headers;
}
};
queue.add(req);

The json values were correctly formatted. Checked by priting jsonbody.get("key")
the slashes are escaped when printing out the json using .toString.
For my case, the 400 error was fixed by adding header:
params.put("Content-Type","application/json; charset=utf-8");

Volley Post method gives me unexpected response code 400?

Here am new for android development am trying to post json value to server using gson lib i have converted into json but when i try to send to server is throws 400 unexpected response code here let me post my code:
listobj = account_sf_db.toServer();
Gson gson = new Gson();
RequestQueue queue = Volley.newRequestQueue(getBaseContext());
final String yog = gson.toJson(listobj);
String URL = "http://xxx.xx.xx.xxx/xxx/CRM/AcoountCreatePageLoad.svc/xxt/xxxt/ " +yog ;
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
String resp = response.toString();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
})
{
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("god", yog);
return params;
} #Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
headers.put("Accept","application/json");
headers.put("User-agent", "My useragent");
return headers;
}
};
queue.add(stringRequest);
stringRequest.setRetryPolicy(new DefaultRetryPolicy(5000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
}

400 status code is for Bad Request, it means server is not expecting this type of request.
The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.
Please check headers(content-type, user agent,etc.) you are adding whether it is required or not. It might happen that server is expecting a simple request and not json request.
Also try to read out error you get in onErrorResponse. Server might have responded you the expected parameter and request type, and also discuss the type of API developed by the web developer.

You have a space in your url after the /xxt/xxxt/
String URL = "http://xxx.xx.xx.xxx/xxx/CRM/AcoountCreatePageLoad.svc/xxt/xxxt/ " +yog ;
Remove it and I think you'll be fine.
P.S 400 generally means there is something wrong with the Url or parameters.

Volley JsonObjectRequest Post parameters no longer work

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);
as per CustomRequest below link
Volley JsonObjectRequest Post request not working

It does work.
I parsed json object response using this:-
works like a charm.
String tag_string_req = "string_req";
Map<String, String> params = new HashMap<String, String>();
params.put("user_id","CMD0005");
JSONObject jsonObj = new JSONObject(params);
String url="" //your link
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
url, jsonObj, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("responce", response.toString());
try {
// Parsing json object response
// 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) {
e.printStackTrace();
Toast.makeText(getApplicationContext(),
"Error: " + e.getMessage(),
Toast.LENGTH_LONG).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(),
error.getMessage(), Toast.LENGTH_SHORT).show();
}
});
AppControllerVolley.getInstance().addToRequestQueue(jsonObjReq, tag_string_req);

It worked for me can try this for calling with Volley for Json type request and response .
public void callLogin(String sMethodToCall, String sUserId, String sPass) {
RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(
Request.Method.POST, ConstantValues.ROOT_URL_LOCAL + sMethodToCall.toString().trim(), addJsonParams(sUserId, sPass),
// JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, object,

} 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!

error response with Json request to Disqus on Volley (Android)

I am trying to connectt to Disqus with their api
(Specifically I am calling to POST https://disqus.com/api/oauth/2.0/access_token/ )
I am using JsonObjectRequest with Volley library for the network calls.
My response is consistently an error with code 400:
11-19 12:48:17.119: E/Volley(16124): [107902] BasicNetwork.performRequest: Unexpected response code 400 for http://disqus.com/api/oauth/2.0/access_token/
I have tried to proxy the request in Charles to see more info, and got this as the error message:
And this is my request as it was recorded by Charles (As you can see I did add the parameter grant_type):
I am calling the same request in the iOS version of my app, and am using the same keys and information, and everything works there. This is why I assume the problem is somewhere in my code, perhaps in the way I add/encode/not encode my parameters... This is the code I use to send the request:
String url = "http://disqus.com/api/oauth/2.0/access_token/";
JSONObject jsonObj = new JSONObject();
try {
jsonObj.put("grant_type", "authorization_code");
jsonObj.put("client_id", publicKey());
jsonObj.put("client_secret", SecretKey());
jsonObj.put("redirect_uri", redirectUrl());
jsonObj.put("code", code);
} catch (JSONException e1) {
e1.printStackTrace();
}
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
url, jsonObj, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
String refreshToekn = (String) response.get("refresh_token");
String accessToekn = (String) response.get("access_token");
String stam = refreshToekn+accessToekn;
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d("Error: " + error.getMessage());
}
});
VolleyController.getInstance().addToRequestQueue(jsonObjReq);
The call always falls into onErrorResponse
I have also tried to use StringRequest and add the parameters in the url with no successes

So I managed to get it to work, but I would love if someone could explain why my solution works.
Basically, instead of using JSONObject and passing it to JsonObjectRequest I used a StringRequest and overrode getParams.
Was I wrong trying to send a POST request with JsonObjectRequest?
This is the entire solution:
String url = "http://disqus.com/api/oauth/2.0/access_token/";
StringRequest stringReq = new StringRequest(Method.POST,
url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
String string = response;
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d("error: " + error.getMessage());
}
}) {
#Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put("grant_type", "authorization_code");
params.put("client_id", publicKey());
params.put("client_secret", SecretKey());
params.put("redirect_uri",redirectUrl());
params.put("code", code);
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;
}
};
VolleyController.getInstance().addToRequestQueue(stringReq);
