I'm trying to use KairosAPI's enroll POST request using Android Volley. However I keep getting Error 1002, image one or more required parameters are missing. I've tried two ways to add the parameters into the body of the JSON, which I've outlined in the code.
This is my code-
public class MainActivity extends AppCompatActivity {
RequestQueue requestQueue;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
postRequestToEnrollPersonInGallery();
}
public void postRequestToEnrollPersonInGallery() {
final String appId = "3e12****";
final String appKey = "156e06fd782a3304f085f***********";
String mainUrl = "https://api.kairos.com/";
String enrollRequestUrl = "enroll";
requestQueue = Volley.newRequestQueue(this);
StringRequest stringRequest = new StringRequest(Request.Method.POST, mainUrl + enrollRequestUrl, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("Volley", response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("Volley", error.toString());
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("Content-Type", "application/json");
params.put("app_id", appId);
params.put("app_key", appKey);
return params;
}
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("image", "https://s-media-cache-ak0.pinimg.com/originals/c6/c0/04/c6c004ec669d92faa36d8ff447884293.jpg");
params.put("subject_id", "12345");
params.put("gallery_name", "FirstGallery");
/*params.put("image", "\"url\":\"https://s-media-cache-ak0.pinimg.com/originals/c6/c0/04/c6c004ec669d92faa36d8ff447884293.jpg\"");
params.put("subject_id", "\"subject_id\":\"12345\"");
params.put("gallery_name", "\"gallery_name\":\"FirstGallery\""); -- i tried this too*/
return params;
}
};
requestQueue.add(stringRequest);
}
}
You aren't posting JSON.
You can either
1) Learn to use JsonObjectRequest
final JSONObject body = new JSONObject();
body.put(... , ...);
Request request = new JsonObjectRequest(url, body, ...);
2) Actually post a JSON String.
StringRequest request = new StringRequest(...) {
#Override
public byte[] getBody() throws AuthFailureError {
JSONObject params = new JSONObject();
params.put("image", "https://s-media-cache-ak0.pinimg.com/originals/c6/c0/04/c6c004ec669d92faa36d8ff447884293.jpg");
params.put("subject_id", "12345");
params.put("gallery_name", "FirstGallery");
return params.toString().getBytes();
}
#Override
public String getBodyContentType() {
return "application/json";
}
};

I am looking to do as per the image says:
Following is the code I am trying to implement from that image:
RequestQueue queue = Volley.newRequestQueue(this);
String url ="https://api.kairos.com/enroll";
StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
Log.i("Response is: " , response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// mTextView.setText("That didn't work!");
}
})
{
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String>();
params.put("app_id", "4985f625");
params.put("app_key", "aa9e5d2ec3b00306b2d9588c3a25d68e");
return params;
}
};
// Add the request to the RequestQueue.
queue.add(stringRequest);
Now I do not get how to add that JSONObject part into my POST Request, and also how to add the Content-Type Header.
I found a similar question here. See the code below. You have to override the getBodyContentType method.
public String getBodyContentType()
{
return "application/json";
}
for content type header you can do the following
StringRequest request = new StringRequest(Request.Method.PUT,
url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
listener.onResponse(response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(#NonNull VolleyError error) {
if (error.networkResponse != null) {
errorListener.onErrorResponse(error.networkResponse.statusCode, null);
} else {
Log.e(TAG, "An error occurred while trying to verify sms: ", error);
errorListener.onErrorResponse(500, null);
}
}
}) {
#NonNull
#Override
protected Map<String, String> getParams() {
return data;
}
#NonNull
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
headers.put("Content-Type",
"application/x-www-form-urlencoded");
return headers;
}
};
And for send Json object I suggest create Json object like this
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("11", 3);
jsonObject.put("12", 4);
jsonObject.put("13", 5);
} catch (JSONException e) {
e.printStackTrace();
}
Then you can pass this object as string by jsonObject.toString() and pass it in parameters like pass any string like the following
#NonNull
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("json", jsonObject.toString();
return params;
}
I'm trying to get access tokens from the server using a volley String request. I have tried making a JsonObjectRequest also. Both are below.
public void getAuthenticationTokens(Object param1, final CustomListener<String> listener)
{
//String url = prefixURL + "this/request/suffix";
String url = "https://lw.xxx.co.uk/connect/token";
StringRequest request = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response) {
// response
Log.e("Response", response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
// error
Log.e("Error.Response", error.networkResponse.toString());
}
}
) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> params = new HashMap<>();
params.put("Content-Type","application/x-www-form-urlencoded");
//..add other headers
return params;
}
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String> ();
params.put("scope", "openid email phone profile offline_access roles");
params.put("resource", "window.location.origin");
params.put("grant_type", "password");
params.put("username", "support#xxx.com");
params.put("password", "tempPxxx");
return params;
}
};
requestQueue.add(request);
.
public void getAuthenticationTokens(Object param1, final CustomListener<String> listener)
{
//String url = prefixURL + "this/request/suffix";
String url = "https://lw.xxx.co.uk/connect/token";
Map<String, Object> jsonParams = new HashMap<>();
jsonParams.put("scope", "openid email phone profile offline_access roles");
jsonParams.put("resource", "window.location.origin");
jsonParams.put("grant_type", "password");
jsonParams.put("username", "support#xxx.com");
jsonParams.put("password", "tempPxxx");
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, new JSONObject(jsonParams),
new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response)
{
Log.d(TAG + ": ", "somePostRequest Response : " + response.toString());
if(null != response.toString())
listener.getResult(response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error)
{
if (null != error.networkResponse)
{
Log.e(TAG + ": ", "Error Response code: " + error.networkResponse.statusCode);
listener.getResult(null);
}
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
// Map<String,String> params = super.getHeaders();
// if(params==null)params = new HashMap<>();
Map<String,String> params = new HashMap<>();
params.put("Content-Type","application/x-www-form-urlencoded");
//..add other headers
return params;
}
};
requestQueue.add(request);
.
I get the following response from the server:
E/Volley: [31388] BasicNetwork.performRequest: Unexpected response code 400 for https://lw.xxx.co.uk/connect/token
.
My colleague who has written the server-side code has asked how to convert the following Angular code (his code that works with the API), to Android.
Can anyone help with this?
getLoginEndpoint(userName: string, password: string): Observable<Response> {
let header = new Headers();
header.append("Content-Type", "application/x-www-form-urlencoded");
let searchParams = new URLSearchParams();
searchParams.append('username', userName);
searchParams.append('password', password);
searchParams.append('grant_type', 'password');
searchParams.append('scope', 'openid email phone profile offline_access roles');
searchParams.append('resource', window.location.origin);
let requestBody = searchParams.toString();
return this.http.post(this.loginUrl, requestBody, { headers: header });
}
The problem was a couple of things.
I replaced "params.put("resource", "window.location.origin"); " with "params.put("resource", "https://lw.xxx.co.uk");"
Also, I found out that Volley ignore the getHeaders override, so I commented that method out and used the following to set the headers.
#Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded";
}
public void getAuthenticationTokens(Object param1, final String userName, final String password, final CustomListener<JSONObject> listener)
{
String url = "https://lw.xxx.co.uk/connect/token";
StringRequest request = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response) {
// response
Log.e("Response", response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
// error
Log.e("Error.Response", error.networkResponse.toString());
}
}
) {
/* #Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> params = new HashMap<>();
params.put("Content-Type","application/x-www-form-urlencoded");
//..add other headers
return params;
}*/
#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("scope", "openid email phone profile offline_access roles");
params.put("resource", "https://lw.xxx.co.uk");
params.put("grant_type", "password");
params.put("username", userName);
params.put("password", password);
return params;
}
#Override
protected VolleyError parseNetworkError(VolleyError response) {
try {
String json = new String(response.networkResponse.data, HttpHeaderParser.parseCharset(response.networkResponse.headers));
Log.e(TAG, "reponse error = " + json);
}catch (Exception e){}
return super.parseNetworkError(response);
}
};
requestQueue.add(request);
}//end of getAuthenticationTokens
I was able to call an HTTP endpoint using Postman and these parameters:
{
"name":"Val",
"subject":"Test"
}
However I am unable to do the same with Volley through Android: Here is trying to use JSONRequest:
HashMap<String, String> params2 = new HashMap<String, String>();
params.put("name", "Val");
params.put("subject", "Test Subject");
JsonObjectRequest jsObjRequest = new JsonObjectRequest
(Request.Method.POST, Constants.CLOUD_URL, new JSONObject(params2), new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
mView.showMessage("Response: " + response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// TODO Auto-generated method stub
mView.showMessage(error.getMessage());
}
});
// Access the RequestQueue through your singleton class.
VolleySingleton.getInstance(mContext).addToRequestQueue(jsObjRequest);
And here is trying StringRequest
private void postMessage(Context context, final String name, final String subject ){
RequestQueue queue = Volley.newRequestQueue(context);
StringRequest sr = new StringRequest(Request.Method.POST, Constants.CLOUD_URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
mView.showMessage(response);
}
}, 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("name", name);
params.put("subject", subject);
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;
}
};
queue.add(sr);
}
When I use JSONRequest, the call POSTs but no parameter is passed and when I use StringRequest I get the error below? How can I pass JSON data to Volley call?
E/Volley: [13053] BasicNetwork.performRequest: Unexpected response code 400 for
Here is the server code that handles the request
public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
var helloRequest = await req.Content.ReadAsAsync<HelloRequest>();
var name = helloRequest?.Name ?? "world";
var responseMessage = $"Hello {personToGreet}!";
log.Info($"Message: {responseMessage}");
return req.CreateResponse(HttpStatusCode.OK, $"All went well.");
}
public class HelloRequest
{
public string Name { get; set; }
public string Subject { get; set; }
}
The server code is expecting a JSON object is returning string or rather Json string.
JsonObjectRequest
JSONRequest sends a JSON object in the request body and expects a JSON object in the response. Since the server returns a string it ends up throwing ParseError
StringRequest
StringRequest sends a request with body type x-www-form-urlencoded but since the server is expecting a JSON object. You end up getting 400 Bad Request
The Solution
The Solution is to change the content-type in the string request to JSON and also pass a JSON object in the body. Since it already expects a string you response you are good there. Code for that should be as follows.
StringRequest sr = new StringRequest(Request.Method.POST, Constants.CLOUD_URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
mView.showMessage(response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mView.showMessage(error.getMessage());
}
}) {
#Override
public byte[] getBody() throws AuthFailureError {
HashMap<String, String> params2 = new HashMap<String, String>();
params2.put("name", "Val");
params2.put("subject", "Test Subject");
return new JSONObject(params2).toString().getBytes();
}
#Override
public String getBodyContentType() {
return "application/json";
}
};
Also there is a bug here in the server code
var responseMessage = $"Hello {personToGreet}!";
Should be
var responseMessage = $"Hello {name}!";
Add the content type in the header
#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;
}
You are using params.put instead of params2.put in your hash map while passing parameters.
because your object name is params2
I am trying hit an api(written in PHP) and posting params with it.
Here is my code:
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
url, null,
new com.android.volley.Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
System.out.println("prerna succes volley "+response.toString());
}
}, new com.android.volley.Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
System.out.println("prerna fail volley "+error.toString());
}
})
{
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> pars = new HashMap<String, String>();
pars.put("Content-Type", "application/x-www-form-urlencoded");
return pars;
}
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("action", "login");
params.put("username", "abc#xyz.com");
params.put("pass", "a");
return params;
}
};
I always get invalid username/password which has been handled in api in case there is invalid username and password.In this case api is not receiving the params.
I tried to do it with retrofit and its working fine with it that means there is no problem at API coding. What am I missing here in case of volley?
Thanks for the support. I am able to solve the problem by changing JsonObjectRequest to StringRequest. i found Volley JsonObjectRequest Post parameters no longer work where I got to know that JsonObjectRequest creates some unexpected problems.
There is my code:
StringRequest jsonObjReq = new StringRequest(Request.Method.POST,
url,
new com.android.volley.Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonObject = new JSONObject(response.toString());
String no = jsonObject.getString("$PhoneNo");
} catch (JSONException e) {
}
}
}, new com.android.volley.Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
System.out.println("prerna fail volley " + error.toString());
}
})
{
#Override
public String getBodyContentType() {
Map<String, String> pars = new HashMap<String, String>();
pars.put("Content-Type", "application/x-www-form-urlencoded");
//return pars;
return "application/x-www-form-urlencoded";
}
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("action", "login");
params.put("username", "abc#xyz.com");
params.put("pass", "a");
return params;
}
};
However I am still trying to figure out why JsonobjectRequest did not work.
As far as I can tell by looking at JsonObjectRequest your 3rd parameter is null, and it indicates the JsonObject request - by the documentation "jsonRequest - A JSONObject to post with the request. Null is allowed and indicates no parameters will be posted along with request."
And after searching again, I saw this thread.
if you are sending your data in raw format you need to try this,first of all make json of your data to be post.
final JSONObject jsonBody = new JSONObject();
jsonBody.put("mobile", phoneNumber);
jsonBody.put("otp", otp.trim());
and you have to override these methods
#Override
public byte[] getBody() throws AuthFailureError {
return jsonBody.toString().getBytes();
}
#Override
public String getBodyContentType() {
return "application/json";
}
if you also have header in your post request you also send that with by following type
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
String auth_token = "bearer" + prefs.getPreferencesString(context, "AuthToken").toString();
params.put("Authorization", auth_token);
return params;
}
Here is the whole code.
final JSONObject jsonBody = new JSONObject();
jsonBody.put("mobile", phoneNumber);
jsonBody.put("otp", otp.trim());
StringRequest sr = new StringRequest(Request.Method.POST, Constraints.Base_URL + "/api/v1/verifyotp", new com.android.volley.Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
progressDialog.dismiss();
JSONObject jsonObject = new JSONObject(response);
int status = jsonObject.getInt("status");
String token = jsonObject.getString("token");
prefs.setPreferencesString(OtpActivity.this, "AuthToken", token);
if (status == 1) {
startActivity(new Intent(getApplicationContext(), WelcomeScreenActivity.class));
overridePendingTransition(R.anim.right_in, R.anim.left_out);
} else if (status == 0) {
Toast.makeText(OtpActivity.this, "Please Enter Otp!", Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
}
}
}, new com.android.volley.Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(OtpActivity.this, "Invalid otp please try again!!", Toast.LENGTH_SHORT).show();
progressDialog.dismiss();
}
}) {
#Override
public byte[] getBody() throws AuthFailureError {
return jsonBody.toString().getBytes();
}
#Override
public String getBodyContentType() {
return "application/json";
}
};
MyApplication.getInstance().addToReqQueue(sr, "jreq");
}
} catch (Exception e) {
}
Try migrating to getHeaders and remove getParams
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("action", "login");
params.put("username", "abc#xyz.com");
params.put("pass", "a");
return pars;
}
Or - Reuse the getParams method
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = getParams();
params.put("Content-Type", "application/x-www-form-urlencoded");
return params;
}
If it is a body request all you need to do is add the extra parameter.
JSONObject body = new JSONObject();
body.put("action", "login");
body.put("username", "abc#xyz.com");
body.put("pass", "a");
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
url, body,
new com.android.volley.Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
System.out.println("prerna succes volley "+response.toString());
}
},
new com.android.volley.Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
System.out.println("prerna fail volley "+error.toString());
}
});
I have tried every single method available on stackoverflow but result remains the same.
I want to send params and also api key in the Authorization field of header using volley.
Here is the code snippet.
holder.comment_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String POSTCOMMENT_URL = Utility.getIPADDRESS()+"comments";
volleySingleton = VolleySingleton.getInstance();
requestQueue = volleySingleton.getRequestQueue();
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, POSTCOMMENT_URL, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.e("Response: " , response.toString());
Toast.makeText(myApplication.getApplicationContext(),response.toString(),Toast.LENGTH_LONG).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(myApplication.getApplicationContext(),"Error", Toast.LENGTH_LONG).show();
}
}){
#Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded; charset=UTF-8";
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("Authorization", getApiKey() );
return params;
}
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<>();
params.put("pid", "39");
params.put("comment", "mobile testing");
return params;
}
};
requestQueue.add(jsonObjectRequest);
}
});
I'm getting this error:
[5333] BasicNetwork.performRequest: Unexpected response code 400 for http://www.XXXXXXXXXXX.com/comments
I have already tested the endpoint using Advanced Rest client, it works and returns the JsonObject with previously added comment.
Here are the results:
{
"error": false
"message": "comment added successfully added!"
"comment_id": "12"
"user_id": "12"
"pid": "39"
"comment": "testing for stackoverflow"
"date of comment": "2016-07-30 13:49:08"
}
Ok, after a long research and stupid rather valuable changes, it finally worked for me.
Here is the working code:
holder.comment_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(final View view) {
final String api_key = getApiKey();
String POSTCOMMENT_URL = Utility.getIPADDRESS()+"comments";
volleySingleton = VolleySingleton.getInstance();
requestQueue = volleySingleton.getRequestQueue();
StringRequest stringRequest = new StringRequest(Request.Method.POST, POSTCOMMENT_URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Toast.makeText(myApplication.getApplicationContext(),response,Toast.LENGTH_LONG).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(myApplication.getApplicationContext(),error.toString(),Toast.LENGTH_LONG).show();
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("Authorization", api_key);
return params;
}
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<>();
params.put("pid", "40");
params.put("comment", "testing");
return params;
}
};
requestQueue.add(stringRequest);
}
});
Note: It worked for me, I'm not sure about others.
Changes are: Change JsonObjectRequest to StringRequest and removing any Content-Type doesn't make any difference, so I removed it.
Also, make sure all the params have some values i.e test it by logging.
