When i upload a file on a Server, it shows an error

Question

When i am uploading file on server through Multipart library.Multipart is showing me file upload successfully but when i saw file in server there is no file on server.

I am using below code.Please check it where i am missing some code or anything else

 String API_URL_POST_COMPLAINT =""; String responseResult = "0"; try { SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences("lusername", Context.MODE_PRIVATE); String userId = sharedPreferences.getString("username", ""); Uri uri = Uri.parse(result.getUri().toString()); String realPath = ImageFilePath.getPath(MainActivity.this, uri); File picturePathFile = new File(realPath); String complaint="Hello"; String apiUrl = API_URL_POST_COMPLAINT + "Token=" + "isuotb4hmtXrOcB0IhHdkDbL7NReoacMpYDHWRUFtWYj7l-Ps2Y=" + "&WOID="+URLEncoder.encode("52326", "UTF-8") +"&DocTitle="+URLEncoder.encode("Hi", "UTF-8")+"&FileName="+picturePathFile; apiUrl.replaceAll(" ", "%20"); apiUrl.replaceAll("\n", "%20"); MyMultipartRequest multipart = new MyMultipartRequest(getApplicationContext(), apiUrl); multipart.addHeaderField("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2"); multipart.addHeaderField("Test-Header", "This is my test Header field"); multipart.addFormField("Token", "isuotb4hmtXrOcB0IhHdkDbL7NReoacMpYDHWRUFtWYj7l-Ps2Y="); multipart.addFormField("WOID", "52326"); multipart.addFormField("DocTitle", "Hello"); multipart.addFilePart("FileName", picturePathFile); System.out.println("complaintFile = " + complaint); System.out.println("picturePathFile = " + picturePathFile); System.out.println("complaintFile = " + picturePathFile.getName()); String responsePost = multipart.finish(); System.out.println("responsePost = " + responsePost); return responsePost; } catch (Exception e) { e.printStackTrace(); responseResult = "0"; } return responseResult;

.Net code is here

[HttpPost] public Result UploadDoc(string Token, int WOID, string DocTitle, string FileName) { if (!Request.Content.IsMimeMultipartContent() || HttpContext.Current.Request.Files.Count == 0) return new Result(Result.ResultCode.NoAction, "File not found"); byte[] lBytes = new byte[HttpContext.Current.Request.Files(0).ContentLength - 1 + 1]; HttpContext.Current.Request.Files(0).InputStream.Read(lBytes, 0, HttpContext.Current.Request.Files(0).ContentLength - 1); Result lRes = UserClass.GetUserFromToken(Token); if (lRes.NoSuccess) return lRes; UserClass lUser = (UserClass)lRes.RetInfo; if (lUser.RoleType == UserClass.UserRoleType.Read_Only) return lRes.Init(Result.ResultCode.NoAction, "Permission Denied for User Role"); if (WorkOrderClass.SearchByUser(WOID.ToString(), lUser, true).Length == 0) lRes.Init(Result.ResultCode.NoAction, "Permission Denied on WO"); return (new DocumentClass() { WorkOrderID = WOID, UploadedBy = lUser.UserID, DocTitle = DocTitle.Trim(), FileName = FileName, Doc = lBytes }).InsertIntoDB; }

Please STOP! defacing your post title!

You have to add the file type (what kind of file you are uploading). And try to upload with okhttp.

private ProgressDialog pDialog; private class FileAsync extends AsyncTask<String, String, String> { @SuppressLint("ResourceType") @Override protected String doInBackground(String... params) { String result = ""; try { OkHttpClient okHttpClient = getOkHttpClient(); MultipartBody.Builder data = new MultipartBody.Builder(); data.setType(MultipartBody.FORM); MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png"); data.addFormDataPart("FileName","file.png", RequestBody.create(MEDIA_TYPE_PNG, picturePathFile)); RequestBody requestBody = data.build(); Request request = new Request.Builder() .url("Your URL").post(requestBody) .build(); Response response = okHttpClient.newCall(request).execute(); result = response.body().string().toString(); Log.e("Result : ", result); } catch (IOException ex) { System.err.println(ex); } return result; } @Override protected void onPreExecute() { super.onPreExecute(); pDialog = new ProgressDialog(activity); pDialog.setMessage("Please wait..."); pDialog.show(); pDialog.setCanceledOnTouchOutside(false); } @Override protected void onPostExecute(String response) { super.onPostExecute(response); if (pDialog != null && pDialog.isShowing()) { pDialog.dismiss(); } if (response != null) { //Do something with your response. } } } public OkHttpClient getOkHttpClient() { return new OkHttpClient.Builder() .connectTimeout(120, TimeUnit.SECONDS) .writeTimeout(120, TimeUnit.SECONDS) .readTimeout(120, TimeUnit.SECONDS) .retryOnConnectionFailure(true) .build(); }
