如何在Android

Question

我正在尝试基于视频的应用程序。我使用下面的方法上传视频文件，当我发送大尺寸的视频文件时，它有更多的时间上传。所以我需要压缩数据，并且视频文件大小应该小于30 MB。我的英文不好原谅我。谁能给我解决我的问题的方法呢？

 private void doFileUpload(){
    HttpURLConnection conn = null;
    DataOutputStream dos = null;
    DataInputStream inStream = null;
    String lineEnd = "rn";
    String twoHyphens = "--";
    String boundary =  "*****";
    int bytesRead, bytesAvailable, bufferSize;
    byte[] buffer;
    int maxBufferSize = 1*1024*1024;
    String responseFromServer = "";
    String urlString = "http://mywebsite.com/upload_audio.php";
    try
    {
     //------------------ CLIENT REQUEST
    FileInputStream fileInputStream = new FileInputStream(new File(selectedPath) );
     // 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="" + selectedPath + """ + 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);
    }
  }

您可以尝试HttpClient jar下载最新的HttpClient jar，将其添加到您的项目中，然后使用以下方法上传视频：

private void uploadVideo(String videoPath) throws ParseException, IOException {

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(YOUR_URL);

FileBody filebodyVideo = new FileBody(new File(videoPath));
StringBody title = new StringBody("Filename: " + videoPath);
StringBody description = new StringBody("This is a video of the agent");
StringBody code = new StringBody(realtorCodeStr);

MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("videoFile", filebodyVideo);
reqEntity.addPart("title", title);
reqEntity.addPart("description", description);
reqEntity.addPart("code", code);
httppost.setEntity(reqEntity);

// DEBUG
System.out.println( "executing request " + httppost.getRequestLine( ) );
HttpResponse response = httpclient.execute( httppost );
HttpEntity resEntity = response.getEntity( );

// DEBUG
System.out.println( response.getStatusLine( ) );
if (resEntity != null) {
System.out.println( EntityUtils.toString( resEntity ) );
} // end if

if (resEntity != null) {
  resEntity.consumeContent( );
} // end if

httpclient.getConnectionManager( ).shutdown( );
} // end of uploadVideo( )
