Request to send an email to the wcf service

Question

I am sending data from android to the wcf service, but getting a Bad request using HttpURLConnection.

Android Code:

`public User RegisterPost(Context context, User rUser) throws UnsupportedEncodingException{ String url = context.getResources().getString(R.string.SERVICE_URL)+ "Signup"; try { JSONObject userValue = new JSONObject(); JSONObject user = new JSONObject(); userValue.put("name", rUser.name); userValue.put("email", rUser.email); userValue.put("password", rUser.password); userValue.put("phone", rUser.phone); userValue.put("nic", rUser.nic); userValue.put("userType", rUser.userType); userValue.put("image", rUser.image); user.put("user", userValue.toString()); String response = postData(url, user); } catch(Exception ex) { ex.printStackTrace(); } return null; }` 

The postData () function is in a single file.

 public String postData(String urlpath, JSONObject json) { HttpURLConnection connection = null; try { URL url=new URL(urlpath); connection = (HttpURLConnection) url.openConnection(); connection.setDoOutput(true); connection.setDoInput(true); connection.setRequestMethod("POST"); connection.setRequestProperty("Content-Type", "application/json"); connection.setRequestProperty("Accept", "application/json"); OutputStreamWriter streamWriter = new OutputStreamWriter(connection.getOutputStream()); Log.d("write data",json.toString()); streamWriter.write(json.toString()); streamWriter.flush(); StringBuilder stringBuilder = new StringBuilder(); if (connection.getResponseCode() == HttpURLConnection.HTTP_OK){ InputStreamReader streamReader = new InputStreamReader(connection.getInputStream()); BufferedReader bufferedReader = new BufferedReader(streamReader); String response = null; while ((response = bufferedReader.readLine()) != null) { stringBuilder.append(response + "\n"); } bufferedReader.close(); Log.d("HTTP_OK response", stringBuilder.toString()); return stringBuilder.toString(); } else { Log.e("else response", connection.getResponseMessage()); return null; } } catch (Exception exception){ Log.e("test", exception.toString()); return null; } finally { if (connection != null){ connection.disconnect(); } } } 

json data transfer for maintenance;

 { "user": "{\"name\":\"rrr rrr\",\"email\":\" [e-mail] \",\"password\":\"123\",\"phone\":\"12333333\",\"nic\":\"44444444\",\"userType\":\"Passenger\",\"image\":\"55akasdfadphpoijpiojasdfasdfasdfasdfasdfasdfasdfasdf\"}" } 

here is the WCF service code;

  [OperationContract] [WebInvoke(Method = "POST", UriTemplate = "/Signup", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] bool Signup(ReturnUserData user); public bool Signup(ReturnUserData user) { user usr = new user(); usr.name = user.name; usr.email = user.email; usr.password = user.password; usr.phone = user.phone; usr.nic = user.nic; usr.userType = user.userType; usr.image = user.image; db.users.Add(usr); db.SaveChanges(); return true; } public class ReturnUserData { public string id { get; set; } public string name { get; set; } public string email { get; set; } public string password { get; set; } public string phone { get; set; } public string userType { get; set; } public string image { get; set; } }

Finally, I realized what the problem is, I have a wrong implementation of my RegisterPost() function, so I am changing the function.

 public User RegisterPost(Context context, User rUser) throws UnsupportedEncodingException{ String url = context.getResources().getString(R.string.SERVICE_URL)+ "Signup"; try { JSONObject newUser = new JSONObject(); newUser.put("name", rUser.name); newUser.put("email", rUser.email); newUser.put("password", rUser.password); newUser.put("phone", rUser.phone); newUser.put("nic", rUser.nic); newUser.put("userType", rUser.userType); newUser.put("image", rUser.image); String response = postData(url, newUser.toString()); Log.d("response", response); if(response!="") { try { JSONObject user = new JSONObject(response); User returnUser = new User( user.getInt("id"),user.getString("name"),user.getString("email"),user.getString("password"),user.getString("phone"),user.getString("nic"),user.getString("userType"), user.getString("street"), user.getString("city"), user.getString("country"), Double.parseDouble(user.getString("lat")), Double.parseDouble(user.getString("lng")),user.getInt("is_login"),user.getInt("is_vehicle_added"), user.getString("reg_id"), user.getInt("isError"), user.getString("errorMessage"), user.getString("image")); return returnUser; } catch (JSONException e) { e.printStackTrace(); } } } catch(Exception ex) { ex.printStackTrace(); } return null; }
