我試圖從SD卡的特定文件夾上傳音頻文件到服務器。但是當我試圖做到這一點，我得到以下錯誤。如何將音頻從SD卡上傳到服務器中android

error: /mnt/sdcard/AudioRecorder: open failed: EISDIR (Is a directory)

和我的全是logcat中如下。

它沒有找到文件路徑，所以返回空值！ – Saqib

@ mrfarts，該代碼使用phonegap我沒有使用過。但謝謝你的回覆。 – InnocentKiller

日誌信息是明確的，你想上傳一個目錄，而不是一個文件：

String existingFileName = Environment.getExternalStorageDirectory() 
       .getPath() + "/AudioRecorder/"

/AudioRecorder /不是音頻文件。您應該在末尾附加音頻文件名。

如果您必須上傳目錄中的所有文件，請考慮在（Intent）服務中執行此操作。

  1. 作爲參數添加的文件名，你的方法：

  2. 在您的活動，循環到文件列表，併爲每個文件：

    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); 
}

  3. 的服務：

    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); 
    } 
}

    希望它有幫助

PS：未測試代碼。

是的，但我想上傳AudioRecorder文件夾內的所有文件，所以我如何實現這一點。 – InnocentKiller

我不知道如何做到這一點。如果有，請發佈任何代碼片段或示例。這將從你身邊得到很大的幫助。 – InnocentKiller

okey，使用IntentService類按順序上傳文件。 – kylexy1357
