Загрузка файла на php-сервере с устройства Android

Я не знаю о вашем коде, но предоставляю вам оба рабочих кода: это для всех типов файлов. Я использовал его для изображения, аудио и для видеофайлов.

Android:

 new UploadFileAsync().execute(""); private class UploadFileAsync extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... params) { try { String sourceFileUri = "/mnt/sdcard/abc.png"; HttpURLConnection conn = null; DataOutputStream dos = null; String lineEnd = "\r\n"; String twoHyphens = "--"; String boundary = "*****"; int bytesRead, bytesAvailable, bufferSize; byte[] buffer; int maxBufferSize = 1 * 1024 * 1024; File sourceFile = new File(sourceFileUri); if (sourceFile.isFile()) { try { String upLoadServerUri = "http://website.com/abc.php?"; // open a URL connection to the Servlet FileInputStream fileInputStream = new FileInputStream( sourceFile); URL url = new URL(upLoadServerUri); // Open a HTTP connection to the URL conn = (HttpURLConnection) url.openConnection(); conn.setDoInput(true); // Allow Inputs conn.setDoOutput(true); // Allow Outputs conn.setUseCaches(false); // Don't use a Cached Copy conn.setRequestMethod("POST"); conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("ENCTYPE", "multipart/form-data"); conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary); conn.setRequestProperty("bill", sourceFileUri); dos = new DataOutputStream(conn.getOutputStream()); dos.writeBytes(twoHyphens + boundary + lineEnd); dos.writeBytes("Content-Disposition: form-data; name=\"bill\";filename=\"" + sourceFileUri + "\"" + lineEnd); dos.writeBytes(lineEnd); // create a buffer of maximum size bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); buffer = new byte[bufferSize]; // read file and write it into form... bytesRead = fileInputStream.read(buffer, 0, bufferSize); while (bytesRead > 0) { dos.write(buffer, 0, bufferSize); bytesAvailable = fileInputStream.available(); bufferSize = Math .min(bytesAvailable, maxBufferSize); bytesRead = fileInputStream.read(buffer, 0, bufferSize); } // send multipart form data necesssary after file // data... dos.writeBytes(lineEnd); dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); // Responses from the server (code and message) serverResponseCode = conn.getResponseCode(); String serverResponseMessage = conn .getResponseMessage(); if (serverResponseCode == 200) { // messageText.setText(msg); //Toast.makeText(ctx, "File Upload Complete.", // Toast.LENGTH_SHORT).show(); // recursiveDelete(mDirectory1); } // close the streams // fileInputStream.close(); dos.flush(); dos.close(); } catch (Exception e) { // dialog.dismiss(); e.printStackTrace(); } // dialog.dismiss(); } // End else block } catch (Exception ex) { // dialog.dismiss(); ex.printStackTrace(); } return "Executed"; } @Override protected void onPostExecute(String result) { } @Override protected void onPreExecute() { } @Override protected void onProgressUpdate(Void... values) { } } 

PHP ::

  <?php if (is_uploaded_file($_FILES['bill']['tmp_name'])) { $uploads_dir = './'; $tmp_name = $_FILES['bill']['tmp_name']; $pic_name = $_FILES['bill']['name']; move_uploaded_file($tmp_name, $uploads_dir.$pic_name); } else{ echo "File not uploaded successfully."; } ?> 

Попробуйте это: это 100% рабочая копия.

Функция загрузки: (Parmeter для функции – это ImagePath)

 public void uploadFile(String sourceFileUri) { String fileName = imagePath; HttpURLConnection conn = null; DataOutputStream dos = null; String lineEnd = "\r\n"; String twoHyphens = "--"; String boundary = "*****"; int bytesRead, bytesAvailable, bufferSize; byte[] buffer; int maxBufferSize = 1 * 1024 * 1024; File sourceFile = new File(imagePath); if (!sourceFile.isFile()) { if (dialog != null && dialog.isShowing()) { dialog.dismiss(); } Log.e("uploadFile", "Source File not exist :"+imagePath); } else { try { // open a URL connection to the Servlet FileInputStream fileInputStream = new FileInputStream(sourceFile); URL url = new URL(Upload_Image_URL); // Open a HTTP connection to the URL conn = (HttpURLConnection) url.openConnection(); conn.setDoInput(true); // Allow Inputs conn.setDoOutput(true); // Allow Outputs conn.setUseCaches(false); // Don't use a Cached Copy conn.setRequestMethod("POST"); conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("ENCTYPE", "multipart/form-data"); conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary); conn.setRequestProperty("uploaded_file", fileName); dos = new DataOutputStream(conn.getOutputStream()); dos.writeBytes(twoHyphens + boundary + lineEnd); dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\"" + fileName + "\"" + lineEnd); dos.writeBytes(lineEnd); // create a buffer of maximum size bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); buffer = new byte[bufferSize]; // read file and write it into form... bytesRead = fileInputStream.read(buffer, 0, bufferSize); while (bytesRead > 0) { dos.write(buffer, 0, bufferSize); bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); bytesRead = fileInputStream.read(buffer, 0, bufferSize); } // send multipart form data necesssary after file data... dos.writeBytes(lineEnd); dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); // Responses from the server (code and message) serverResponseCode = conn.getResponseCode(); String serverResponseMessage = conn.getResponseMessage(); Log.i("uploadFile", "HTTP Response is : " + serverResponseMessage + ": " + serverResponseCode); //close the streams // fileInputStream.close(); dos.flush(); dos.close(); } catch (MalformedURLException ex) { if (dialog != null && dialog.isShowing()) { dialog.dismiss(); } ex.printStackTrace(); Log.e("Upload file to server", "error: " + ex.getMessage(), ex); } catch (Exception e) { if (dialog != null && dialog.isShowing()) { dialog.dismiss(); } e.printStackTrace(); } if (dialog != null && dialog.isShowing()) { dialog.dismiss(); } } // End else block } 

Служба Php:

  $file_path = "images/"; $file_path = $file_path . basename( $_FILES['uploaded_file']['name']); if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) { echo "success"; } else{ echo "fail";} 

Необходимо создать папку «images» на сервере

Если вы используете бесплатный хостинг, страницы перенаправляются для отслеживания нет. хитов. Вероятно, вы получите Http Response: 200 OK, но вы не увидите загруженный файл, потому что файл потерян.

Я сам потратил 3 дня на поиски решения, но ничего не нашел. Выяснил это сам.
