我正在尝试将音频文件从 SD 卡的特定文件夹上传到服务器。但是当我尝试这样做时，我收到以下错误。
错误:/mnt/sdcard/AudioRecorder:打开失败:EISDIR(是一个目录)

最佳答案
日志消息很清楚，您正在尝试上传目录，而不是文件:
String existingFileName = Environment.getExternalStorageDirectory()
.getPath() + "/AudioRecorder/"
/AudioRecorder/不是音频文件。您也许应该在末尾附加音频文件名。
如果您必须上传目录中的所有文件，请考虑在( Intent )服务中执行此操作。
- 将文件名作为参数添加到您的方法中:
在您的 Activity 中，循环进入文件列表，并为每个文件:
for(String filename : filesList ){ Intent intent = new Intent(this, UploadIntentService.class); Bundle params = new Bundle(); params.putString(UploadIntentService.KEY_FILE_NAME, filename); activity.startService(intent); }服务:
public class UploadIntentService extends IntentService { public static final String KEY_FILE_NAME= "filename"; public UploadIntentService() { super("UploadIntentService"); } @Override protected void onHandleIntent(Intent intent) { String filename = intent.getBundle().getStringExtra(UploadIntentService.KEY_FILE_NAME); doAudioFileUpload(filename); } private void doAudioFileUpload(String filename) { HttpURLConnection conn = null; DataOutputStream dos = null; DataInputStream inStream = null; String existingFileName = Environment.getExternalStorageDirectory() .getPath() + "/AudioRecorder/"+filename; System.out.println("Inside of doupload nd path is === " + existingFileName); String lineEnd = "\r\n"; String twoHyphens = "--"; String boundary = "*****"; int bytesRead, bytesAvailable, bufferSize; byte[] buffer; int maxBufferSize = 1 * 1024 * 1024 * 1024; String urlString = "http://link to server/folder-name/upload_audio.php"; try { // ------------------ CLIENT REQUEST FileInputStream fileInputStream = new FileInputStream(new File( existingFileName)); // open a URL connection to the Servlet URL url = new URL(urlString); // Open a HTTP connection to the URL conn = (HttpURLConnection) url.openConnection(); // Allow Inputs conn.setDoInput(true); // Allow Outputs conn.setDoOutput(true); // Don't use a cached copy. conn.setUseCaches(false); // Use a post method. conn.setRequestMethod("POST"); conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary); dos = new DataOutputStream(conn.getOutputStream()); dos.writeBytes(twoHyphens + boundary + lineEnd); dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + existingFileName + "\"" + 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); // close streams Log.e("Debug", "File is written"); fileInputStream.close(); dos.flush(); dos.close(); } catch (MalformedURLException ex) { Log.e("Debug", "error: " + ex.getMessage(), ex); } catch (IOException ioe) { Log.e("Debug", "error: " + ioe.getMessage(), ioe); } // ------------------ read the SERVER RESPONSE try { inStream = new DataInputStream(conn.getInputStream()); String str; while ((str = inStream.readLine()) != null) { Log.e("Debug", "Server Response " + str); } inStream.close(); } catch (IOException ioex) { Log.e("Debug", "error: " + ioex.getMessage(), ioex); } }希望对你有帮助
