I have a POST method send a JsonObject via Volley:
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, postBody, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
log("success");
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
log("" + error);
}
});
request.setRetryPolicy(new DefaultRetryPolicy(10000, 0, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
Volley.newRequestQueue(this).add(request);
With postBody:
JSONObject postBody = new JSONObject();
try {
postBody.put("name", "rome");
//postBody.put("image", file?);
} catch (JSONException e) {
log("" + e);
}
I want to send a image file with key "image" above. This file type is the same with file of form-data in PostMan (not url of file).
Is there anyway to do it? Thanks.

I am hitting API on the server. It is working perfectly but when I run it in my app I am getting volley onErrorResponse along with data . I am not able to understand how it is possible. I am sharing code and error image. Please check.
private void callProductsApi() {
String tag_json_obj = "json_obj_req";
String url = Constants.GET_PRODUCTS;
pBar.setVisibility(View.VISIBLE);
JSONObject params = new JSONObject();
try {
params.put("token", Constants.token);
} catch (Exception e) {
e.printStackTrace();
}
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
url, params,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.e("login_response", response.toString());
pBar.setVisibility(View.GONE);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.e("Error: " + error.getMessage());
Toast.makeText(Splash.this, R.string.some_error_occured, Toast.LENGTH_LONG).show();
pBar.setVisibility(View.GONE);
}
});
jsonObjReq.setRetryPolicy(new DefaultRetryPolicy(
100000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
AppController.getInstance().addToRequestQueue(jsonObjReq, tag_json_obj);
}
The api should return success code which is 200, 201 and so on response. if it returns
other response in line of 400 or 500 it will display the correct json but in error method.
I have build a laravel Rest API with a Jason Web Token. Now I want to make a App which sends data to the Webservice. Here I try to authentificate myself (with name email and password) at first but I do not get the token as a answer. I also do not get a error, nothing happens.
private void sendAndRequestResponse() {
try {
JSONObject jsonBody = new JSONObject();
jsonBody.put("name", "ida");
jsonBody.put("email", "ida#gmail.com");
jsonBody.put("password", "secret");
final String mRequestBody = jsonBody.toString();
//RequestQueue initialized
mRequestQueue = Volley.newRequestQueue(this);
mJsonRequest = new JsonObjectRequest(
Request.Method.POST, url, jsonBody,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
answer.setText(response.toString());
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
});
mRequestQueue.add(mJsonRequest);
} catch (JSONException e) {
e.printStackTrace();
}
}
you need to start request queue in order to make the request call.
after
mRequestQueue.add(mJsonRequest);
add following
mRequestQueue.start();
I want to call API Using Volley. There is an Multiple object Request So i don't Know Proper way. I was tried to code as below.But it does not give me Response.So can Anyone help me???
MainActivity
public void getJsonResponsePost(){
JSONObject jsonData = new JSONObject();
JSONObject json = new JSONObject();
/*{"data":{"lang_type":"1","keyword":"","latitude":23.022499999999997,"longitude":72.57139833333333,"category":6}}*/
try {
jsonData.put("data",json);
json.put("lang_type","1");
json.put("keyword","");
json.put("latitude",23.022499999999997);
json.put("longitude",72.57139833333333);
json.put("category",6);
Log.d("TAG",jsonData.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, json, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response)
{
Log.d("String Response :",response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d(" Error getting :",error.toString());
}
});
jsonObjectRequest.setTag(REQ_TAG);
requestQueue.add(jsonObjectRequest);
}
I get the following response
String Response :: {"status":"0","message":"Please pass the language type."}
Can you try this?
try {
json.put("lang_type","1");
json.put("keyword","");
json.put("latitude",23.022499999999997);
json.put("longitude",72.57139833333333);
json.put("category",6);
jsonData.put("data",json);
Log.d("TAG",jsonData.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, jsonData, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response)
{
Log.d("String Response :",response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d(" Error getting :",error.toString());
}
});
I have a web api setup and one of the endpoints in the API takes a JSON object (which in the API gets resolved to a .NET object).
Using Postman I can successfully call the post endpoint, here is the URL
https://example.com/api/helprequests
And here is the JSON which I include in the Postman request
{"Title":"Test Title", "Message":"Test Message"}
Everything works well in Postman, but I am trying to call this API from an Android app using Volley.
Here is the relevant code
String webAddress = "http://example.com/api/helprequests/";
RequestQueue queue = Volley.newRequestQueue(this);
StringRequest stringRequest = new StringRequest(Request.Method.POST, webAddress,
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("RESPONSE", "That didn't work!");
}
}) {
#Override
public String getBodyContentType() {
return "application/json";
}
#Override
public byte[] getBody() throws AuthFailureError {
try {
Map<String, String> params = new HashMap<String, String>();
params.put("Title","Test title");
params.put("Message", "Test message");
} catch (Exception ex) {
VolleyLog.wtf("Unsupported Encoding");
return null;
}
return null;
}
};
queue.add(stringRequest);
When I run this I get the following error:
E/Volley: [50225] BasicNetwork.performRequest: Unexpected response code 500 for https://example.com/api/helprequests
How do I add post data to a Volley request?
Instead of using the StringRequest do use JsonObjectRequest.
String webAddress = "http://example.com/api/helprequests/";
RequestQueue queue = Volley.newRequestQueue(this);
JSONObject object = new JSONObject();
try {
object.put("Title", "my title");
object.put("Message", "my message");
} catch (JSONException e) {
}
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, webAddress,object, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject object) {
Log.d("RESPONSE", object.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError volleyError) {
Log.d("RESPONSE", "That didn't work!");
}
});
queue.add(request);
String webAddress = "http://example.com/api/helprequests/";
RequestQueue queue = Volley.newRequestQueue(this);
JSONObject jsonObject= new JSONObject();
try {
jsonObject.put("Title", "my title");
jsonObject.put("Message", "my message");
} catch (JSONException e) {
}
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
JsonObjectRequestWithHeader jsonObjReq = new JsonObjectRequestWithHeader(Request.Method.POST,
webAddress , jsonObject, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.v("Response0", response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d("Response", "Error: " + error.getMessage());
pd.dismiss();
}
});
int socketTimeout = 50000;//30 seconds - change to what you want
RetryPolicy policy = new DefaultRetryPolicy(socketTimeout, DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
jsonObjReq.setRetryPolicy(policy);
queue.add(jsonObjReq);
return null;
}
Hi I am a beginner in Android , I am learning to make Api Calls. I got a tutorial of Volley which uses GET to Receive response. Now I want to Send Post request Using Volley. I don't know how to do that, what would be the code for POST in the given Tutorial. Please guide me to send Post Request.The link to the tutorial that I am learning is http://www.truiton.com/2015/02/android-volley-example/
you have to used below code to send request
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(this);
String url ="http://www.google.com";
// Request a string response from the provided URL.
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.
mTextView.setText("Response is: "+ response.substring(0,500));
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mTextView.setText("That didn't work!");
}
});
// Add the request to the RequestQueue.
queue.add(stringRequest);
try {
/** json object parameter**/
JSONObject jsonObject = new JSONObject();
jsonObject.put("hello", "hello");
Log.e("jsonObject params", jsonObject.toString() + "");
/**URL */
String url ="http://google.com"
progress.setVisibility(View.VISIBLE);
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, jsonObject, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject jsonObject) {
progress.setVisibility(View.GONE);
Log.e(TAG, "Response " + jsonObject.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError volleyError) {
progress.setVisibility(View.GONE);
Log.e(TAG, volleyError);
Util.showToast(activity, "Please try again");
}
});
requestQueue.add(jsonObjectRequest);
} catch (JSONException e) {
progress.setVisibility(View.GONE);
Log.e(TAG, e);
}
catch (Exception e) {
progress.setVisibility(View.GONE);
Log.e(TAG, e);
}
}
}
RequestQueue queue = Volley.newRequestQueue(this);
queue.add(jsonObjectRequest);
You can follow this :http://www.androidhive.info/2014/05/android-working-with-volley-library-1/
StringRequest request = new StringRequest(Method.POST,
"post url",
new ResponseListener() {
#Override
public void onResponse(String response) {
Log.d("response", response);
} catch (Exception e) {
e.printStackTrace();
}
}
}, new ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("response","error");
}
}) {
// post params
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("param", "param");
return params;
}
};
//2.Use your custom volley manager send request or like this
Volley.newRequestQueue(mCtx).add(request);
