從android設備發送文件到服務器？

Question

如何將所有文件從SD卡發送到服務器，我可以從設備通過該 代碼推文件服務器：

public void btnclick(View v) { 

     String pathToOurFile = "/mnt/sdcard/" + "q.3gp"; 
     String urlServer = "http://www.google.com/upload.php"; 
     String lineEnd = "\r\n"; 
     String twoHyphens = "--"; 
     String boundary = "*****"; 
     int bytesRead, bytesAvailable, bufferSize; 
     byte[] buffer; 
     int maxBufferSize = 1 * 1024 * 1024; 

     try { 

      FileInputStream fileInputStream = new FileInputStream(new File(
        pathToOurFile)); 

      URL url = new URL(urlServer); 
      connection = (HttpURLConnection) url.openConnection(); 

      // Allow Inputs & Outputs 
      connection.setDoInput(true); 
      connection.setDoOutput(true); 
      connection.setUseCaches(false); 
      connection.setRequestMethod("POST"); 
      connection.setRequestProperty("Connection", "Keep-Alive"); 
      connection.setRequestProperty("ENCTYPE", "multipart/form-data"); 
      connection.setRequestProperty("Content-Type", 
        "multipart/form-data;boundary=" + boundary); 
      connection.setRequestProperty("uploaded_file", "gopivideo"); 
      outputStream = new DataOutputStream(connection.getOutputStream()); 
      outputStream.writeBytes(twoHyphens + boundary + lineEnd); 
      outputStream 
        .writeBytes("Content-Disposition: form-data; name=\"sample\";filename=\"" 
          + pathToOurFile + "\"" + lineEnd); 
      outputStream.writeBytes(lineEnd); 

      bytesAvailable = fileInputStream.available(); 
      bufferSize = Math.min(bytesAvailable, maxBufferSize); 
      buffer = new byte[bufferSize]; 

      // Read file 
      bytesRead = fileInputStream.read(buffer, 0, bufferSize); 

      while (bytesRead > 0) { 
       outputStream.write(buffer, 0, bufferSize); 
       bytesAvailable = fileInputStream.available(); 
       bufferSize = Math.min(bytesAvailable, maxBufferSize); 
       bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
      } 

      outputStream.writeBytes(lineEnd); 
      outputStream.writeBytes(twoHyphens + boundary + twoHyphens 
        + lineEnd); 

      // Responses from the server (code and message) 
      int serverResponseCode = connection.getResponseCode(); 
      String serverResponseMessage = connection.getResponseMessage(); 

      Toast.makeText(getApplicationContext(), 
        serverResponseCode + "," + serverResponseMessage, 
        Toast.LENGTH_LONG).show(); 

      fileInputStream.close(); 
      outputStream.flush(); 
      outputStream.close(); 
     } catch (Exception ex) { 
      // Exception handling 
     } 
    } 
} 

這是上傳任何類型的文件到服務器單推 但什麼是工作很酷需要循環SD卡中的所有文件並逐個發送。 謝謝

爲此，您可以用多個部分的POST請求：（這樣，你不需要創建JSON）

HttpClient client = new DefaultHttpClient(); 
    HttpPost post = new HttpPost(serverURL); 
    MultipartEntity postEntity = new MultipartEntity(); 
    File file = new File("Your File path on SD card"); 
    postEntity.addPart("fileupload", new FileBody(file, "image/jpeg")); 
    postEntity.addPart("loginKey", new StringBody(""+loginKey)); 
    postEntity.addPart("message", new StringBody(message)); 
    postEntity.addPart("token", new StringBody(token)); 
    post.setEntity(postEntity); 
    response = client.execute(post); 

，並添加Mime4庫
