I am using simmilar fucntion for creating GET and POST api requests, but the GET function set textview to response body and I dont know how to read the status code and the POST function set textview to the response code and I dont know how to read response body. Can you help me, please?
I also tried to log in parseNetworkResponse() response.data.toString() but thats is not the data that api returns. Maybe I need to encode it somehow?
public void createGet(Context context, String url) {
final TextView apiResultTextview = (TextView) ((Activity)
context).findViewById(R.id.api_result_textview);
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(context);
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
apiResultTextview.setText("Response is: " + response.substring(0, 50));
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
apiResultTextview.setText(error.toString());
}
});
// Add the request to the RequestQueue.
queue.add(stringRequest);
}
public void createPost(Context context, String url, JSONObject body) {
final TextView apiResultTextview = (TextView) ((Activity) context).findViewById(R.id.api_result_textview);
RequestQueue requestQueue = Volley.newRequestQueue(context);
final String mRequestBody = body.toString();
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Log.i("LOG_RESPONSE", response);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("LOG_RESPONSE", error.toString());
}
}) {
@Override
public String getBodyContentType() {
return "application/json; charset=utf-8";
}
@Override
public byte[] getBody() throws AuthFailureError {
try {
return mRequestBody == null ? null : mRequestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", mRequestBody, "utf-8");
return null;
}
}
@Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String responseString = "";
if (response != null) {
responseString = String.valueOf(response.statusCode);
apiResultTextview.setText("Response is: " + responseString);
}
return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
}
};
requestQueue.add(stringRequest);
}
add this code in you onResponse() Method
JSONObject jsonObj = new JSONObject(response);
String response_value = jsonObj.getString("response");
I solved it by changing method for call to code below. Problem was probably in JsonObjectRequest vs StringRequest. That's why I was getting only response code string.
public void createCall(int type, String url, JSONObject data, final int callback) {
JsonObjectRequest jsonRequest = new JsonObjectRequest(type, url,data,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.d("Response", response.toString());
try {
callback(response, callback);
} catch (Exception e){
Log.d("API callback error", e.getMessage());
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.d("Error response", error.toString());
}
}
);
queue.add(jsonRequest);
}
