I'm new to google's Volley network library (and also to Android !), and I'm trying to pass POST arguments in a dynamic way !
For now I am overiding the : getParams() method :
And returning the params in an hard coded manner.
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String>();
params.put("login", "my_login");
params.put("password", "my_password");
return params;
}
I would like to pass variables instead of "hard coded" strings...
First I tried to put my Map of params as a member of my class, but class members are not avaible in the getParams() method.
Maybe I could use a singleton class to wich I could give the parameters I want to pass and get them back using its instance in the getParams() method ? But I don't think that it would be the right manner.
Below is the hole code of my Volley's request :
RequestQueue queue = VolleySingleton.getInstance().getRequestQueue();
String url = "https://theUrlToRequest";
StringRequest postRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response) {
JSONObject mainObject = null;
try {
Log.i("app", "Result = " + response);
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
Log.i("app", "Fail on Login" + error.toString());
}
}
) {
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String>();
params.put("login", "my_login");
params.put("password", "my_password");
return params;
}
};
queue.add(postRequest);
In that case , you can create a Class extends StringRequest. Add an attr to store params and return it in getParams();
MyStringRequest extends StringRequest{
private Map params = new HashMap();
public MyStringRequest (Map params,int mehotd,String url,Listener listenr,ErrorListener errorListenr){
super(mehotd,url,listenr,errorListenr)
this.params = params
}
#Override
protected Map<String, String> getParams(){
return params;
}
}
RequestQueue queue = VolleySingleton.getInstance().getRequestQueue();
String url = "https://theUrlToRequest";
Map<String, String> params = new HashMap<String, String>();
params.put("login", "my_login");
params.put("password", "my_password");
MyStringRequest postRequest = new MyStringRequest (params ,Request.Method.POST, url,
new Response.Listener<String>(){
},
new Response.ErrorListener(){
}
);
queue.add(postRequest);

I am adding contacts to active campaign api but the request is not sending the post parameters.The parameters are being sent from postman but with volley its not working. I have tried sending params from the constructor also but no progress. Here is the code.
Map<String, String> params = new HashMap();
params.put("email", "wff#dd.com");
params.put("p[1]", "1");
//JSONObject parameters = new JSONObject(params);
RequestQueue queue = Volley.newRequestQueue(MainActivity.this);
url="https://brumano.api-us1.com/admin/api.php?api_key=key&api_action=contact_add&api_output=json";
Log.d("url",url);
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST,url,null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("url",response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// TODO Auto-generated method stub
Log.d("url",error.toString());
error.printStackTrace();
}
}){
#Override
public byte[] getBody() {
HashMap<String, String> params2 = new HashMap<String, String>();
params2.put("email", "w#sss.com");
params2.put("p[1]", "1");
return new JSONObject(params2).toString().getBytes();
}
#Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded;";
}
#Override
protected Map<String, String> getParams() {
Map<String, String> params2 = new HashMap<String, String>();
params2.put("email", "w#sss.com");
params2.put("p[1]", "1");
return params2;
}
}
};
queue.add(jsObjRequest);
Try this using StringRequest
StringRequest jsonObjRequest = new StringRequest(Request.Method.POST,
"https://brumano.api-us1.com/admin/api.php?api_key=key&api_action=contact_add&api_output=json",
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("url",response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d("volley", "Error: " + error.getMessage());
}
}) {
#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", "w#sss.com");
params.put("p[1]", "1");
return params;
}
};
queue.add(jsonObjRequest);
check this, with stringRequest like this
//Tested on PostMan
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("userName", "cyborg91mv#gmail.com");
params.put("password", "qwerty");
System.out.println(params);
return params;
}
Now if your server expects json, then make jsonRequest
JSONObject jsonObjectBody = new JSONObject();
jsonObjectBody.put("userName", "cyborg91mv#gmail.com");
jsonObjectBody.put("password", "qwerty");
When I am trying to fetch data through rest api using Volley StringRequest or JsonObjectRequest. I always get 400 error. Its working fine with the postman. Http request method is POST, Content-Type is application/x-www-form-urlencoded. I have also checked my parameter spelling and it looks fine to me. I have tried with both StringRequest and JsonObjectRequest, result is E/Volley: [10283] BasicNetwork.performRequest: Unexpected response code 400. Below is my code. I have attached a screenshot.
Here is the new screenshot
StringRequest stringRequest = new StringRequest(Request.Method.POST, AppConfig.URL_LOGIN, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d(TAG, response.toString());
viewHelper.hideDialog();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d(TAG, error.toString());
viewHelper.hideDialog();
}
}){
#Override
protected Map<String, String> getParams() {
// Posting parameters to login url
Map<String, String> params = new HashMap<String, String>();
params.put("grant_type", "password");
params.put("username", email);
params.put("password", password);
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;
}
#Override
public String getBodyContentType(){
return "application/x-www-form-urlencoded";
}
};
stringRequest.setRetryPolicy(new DefaultRetryPolicy(5000, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
// Adding request to request queue
AppController.getInstance().addToRequestQueue(stringRequest, "Authenticating User");
I have alos tried with volley JSONObjectRequest
Map<String, String> params = new HashMap<String, String>();
params.put("grant_type", "password");
params.put("username", email);
params.put("password", password);
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, AppConfig.URL_LOGIN, new JSONObject(params), new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/x-www-form-urlencoded");
return headers;
}
};
Can anyone please help me in fixing this issue.
Below is the working example of POST request using Volley library.
Add this to your build.gradle (Module:app) -
compile 'com.mcxiaoke.volley:library:1.0.19'
StringRequest stringRequest = new StringRequest(Request.Method.POST, AppConfig.URL_LOGIN, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d(TAG, response.toString());
progressDialog.dismiss();
JSONObject jsonObject = null;
try {
jsonObject = new JSONObject(response);
if(jsonObject.has("success")){
if(jsonObject.getBoolean("success") == true){
JSONObject userObject = new JSONObject(jsonObject.getString("user"));
Map<String, String> loginDetails = new HashMap<String, String>();
loginDetails.put(KEY_IS_LOGGED_IN, "true");
loginDetails.put(ACCESS_TOKEN, jsonObject.getString(ACCESS_TOKEN));
loginDetails.put(USERID, userObject.getString(USERID));
loginDetails.put(FIRSTNAME, userObject.getString(FIRSTNAME));
loginDetails.put(LASTNAME, userObject.getString(LASTNAME));
loginDetails.put(EMAIL, userObject.getString(EMAIL));
session = new SessionManager(_myActivity);
session.setLogin(loginDetails);
Intent intent = new Intent(LoginActivity.this, SearchActivity.class);
intent.putExtra("FROM_ACTIVITY", "LoginActivity");
startActivity(intent);
LoginActivity.this.finish();
}else{
btnLogin.setClickable(true);
btnLogin.setEnabled(true);
Toast.makeText(getApplicationContext(), "Username or Password does not matched!", Toast.LENGTH_LONG).show();
}
}
} catch (JSONException e) {
btnLogin.setClickable(true);
btnLogin.setEnabled(true);
e.printStackTrace();
Toast.makeText(getApplicationContext(), "Something went wrong, Please try agian", Toast.LENGTH_LONG).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d(TAG, error.toString());
progressDialog.dismiss();
btnLogin.setClickable(true);
btnLogin.setEnabled(true);
}
}){
#Override
protected Map<String, String> getParams() {
// Posting parameters to login url
Map<String, String> params = new HashMap<String, String>();
params.put("grant_type", "password");
params.put("username", email);
params.put("password", password);
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;
}
#Override
public String getBodyContentType(){
return "application/x-www-form-urlencoded";
}
};
stringRequest.setRetryPolicy(new DefaultRetryPolicy(5000, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
// Adding request to request queue
RequestQueue mRequestQueue = Volley.newRequestQueue(getApplicationContext());
mRequestQueue.add(stringRequest);
Please comment if anyone faced issue with above code.
Thanks to everyone who tried to help me.
A 400 means bad request the data sent by the you to the server didn't follow the rules.So check your parameter or spelling of these parameter which is required by server.
So check those try again hope it work for you :)
Unexpected response code 400 means Bad Reuest.
This Response is caused by sending wrong parameters with the URL.
To solve:
Check every parameter with spelling.
Make sure if response is obtained in string or in object. stringRequest or JSONObjectReuest
Also check Content-type
use this as Content-type
#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;
}
For JsonObjectReuest use:
HashMap<String, String> params = new HashMap<String, String>();
params.put("name", "BLah");
JsonObjectRequest req = new JsonObjectRequest(URL, new JSONObject(params),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
Log.d("Response:", response.toString());
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("Error: ", error.getMessage());
}
});
This is how I am sending a request
// Tag used to cancel the request
String tag_json_obj = "string_req";
String url = getResources().getString(R.string.ybase_path)+"strings_u.php";
String tag_string_req = "req_login";
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Toast.makeText(getActivity(), response.toString(),
Toast.LENGTH_LONG).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError volleyError) {
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("a_id", application_id);
return params;
}
#Override
public Map<String, String> getHeaders(){
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "text/html");
//headers.put("apiKey", "xxxxxxxxxxxxxxx");
return headers;
}
};
AppController.getInstance().addToRequestQueue(stringRequest,tag_string_req);
and on the server side I am handling the request as
if(isset($_GET['a_id']))
But it seems the parameters are not sent only. I've been looking for the solution since two days with no luck.
You need to use Request.Method.POST instead of Request.Method.GET to send parameters
StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
// ^^^^
For further reading
UPDATE : you should use if(isset($_POST['a_id'])) instead of if(isset($_GET['a_id']))
I google and I tried to post string request by attaching headers. But I always get auth failure error.It seems my header is not setting properly. Here is my code
StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("response",response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
if (error!=null){
error.printStackTrace();
}
}
}){
#Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put("client_id=",getString(R.string.client_id));
params.put("&client_secret=",getString(R.string.client_secret));
params.put("&grant_type=","authorization_code");
params.put("&code=",accessToken);
return params;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> params = new HashMap<String, String>();
params.put("Authorization", "Basic " + base64);
params.put("Content-Type", "application/x-www-form-urlencoded");
params.put("Accept", "*/*" );
return super.getHeaders();
}
};
RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
requestQueue.add(stringRequest);
I attached headers in getHeaders() and stream writer in getParams().Can somebody help me to resolve this.Thanks in advance.
Dont put params like this
params.put("&grant_type=","authorization_code");
replace like this
params.put("grant_type", authorization_code);
Dont add & and = sign it will automatically included.
#Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put("client_id",getString(R.string.client_id));
params.put("client_secret",getString(R.string.client_secret));
params.put("grant_type","authorization_code");
params.put("code",accessToken);
return params;
}
try header like this
#Override
public Map getHeaders() throws AuthFailureError {
Map headers = new HashMap();
headers.put("appId", "MYAPP_ID_HERE");
return headers;
}
I have an API endpoint which needs parameters to be sent as JsonObject in a POST request.
The response which I will get is not Json, but rather a small CSV string.
The Code is
stringRequest = new StringRequest(Request.Method.GET, "http://apitest.eezyrent.com/api/userauthentication/SignUp",
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
Toast.makeText(getApplication(), response.toString(), Toast.LENGTH_SHORT).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplication(), error.getMessage(), Toast.LENGTH_SHORT).show();
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> jsonParams2 = new HashMap<String, String>();
jsonParams2.put("vcFName", firstname.getText().toString());
jsonParams2.put("vcLname", lastname.getText().toString());
jsonParams2.put("vcMobileNo", phone_no.getText().toString());
jsonParams2.put("vcGender", gender_short);
jsonParams2.put("vcEmailAddress", email.getText().toString());
jsonParams2.put("vcPassword", password.getText().toString());
jsonParams2.put("vcFBID", "");
jsonParams2.put("intLoginUserID", "");
jsonParams2.put("SignUpFrom", "Web");
jsonParams2.put("intloginid", "");
jsonParams2.put("AlreadyRegister", "");
return jsonParams2;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
headers.put( "charset", "utf-8");
return headers;
}
};
The above code is heavily inspired by using answers from this community, but this does not seem to solve the problem for me.
I get Volley Error 405.
E/Volley﹕ [112549] BasicNetwork.performRequest: Unexpected response code 405 for http://myurl
Infact If I used AsyncTask instead of Volley, With the same json as parameters and the same endpoint url. It works!! The AsyncTask code was found from this question. Java HttpClient changing content-type?
But I want to use Volley, What could be the solution to this?
Sample JSON Object
{"vcFName":"Ron","vcLname":"Weasley","vcMobileNo":"555888999","vcGender":"M","vcEmailAddress":"someone#somewhere.com","vcPassword":"123456","vcFBID":"","intLoginUserID":'',"SignUpFrom":"Web","intloginid":"","AlreadyRegister":""}
You need to use JsonObjectRequest class. Pass your params as json object in the 3rd parameter of the JsonObjectRequest class. Below is a small snippet:
Map<String, String> jsonParams2 = new HashMap<String, String>();
jsonParams2.put("vcFName", firstname.getText().toString());
jsonParams2.put("vcLname", lastname.getText().toString());
jsonParams2.put("vcMobileNo", phone_no.getText().toString());
jsonParams2.put("vcGender", gender_short);
jsonParams2.put("vcEmailAddress", email.getText().toString());
jsonParams2.put("vcPassword", password.getText().toString());
jsonParams2.put("vcFBID", "");
jsonParams2.put("intLoginUserID", "");
jsonParams2.put("SignUpFrom", "Web");
jsonParams2.put("intloginid", "");
jsonParams2.put("AlreadyRegister", "");
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
YourUrl, new JsonObject(jsonParams2),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
headers.put( "charset", "utf-8");
return headers;
}
};
Step 1: Make model class parsable/Serializable.
Step 2: Override toString() in model class.
Step 3:
Map<String,JSONObject> params = new HashMap<>();
JSONObject object = null;
try{
object = new JSONObject(classObject.toString());
}catch (Exception e){
}
params.put("key", object);
JSONObject objectParams = new JSONObject(params);
Step 4: Send objectParams with volley JSONObject request.
Done!!!
