Answer 1

使用Apache FTP客户端

http://commons.apache.org/net/download_net.cgi

示例代码：

public static FTPClient uploadingFilestoFtp() throws IOException 
    { 
    FTPClient ftpClient = new FTPClient(); 
    ftpClient.connect(InetAddress.getByName(host)); 
    ftpClient.login(username,password); 
     ftpClient.changeWorkingDirectory(workdir); 
     return ftpClient; 
    } 


class UploadVideo extends AsyncTask<String,Integer,String> 
    { 

     @Override 
     protected String doInBackground(String... params) 
     { 
      // TODO Auto-generated method stub 
      try 
      { 
      ftpClient=uploadingFilestoFtp(); 
      ftpClient.setFileType(FTP.BINARY_FILE_TYPE); 
      ftpClient.enterLocalPassiveMode(); 
      File file = new File(params[0]); 
      videoFileSize=file.length(); 
      BufferedInputStream buffIn = new BufferedInputStream(
        new FileInputStream(file)); 
      ProgressInputStream progressInput = new ProgressInputStream(buffIn); 
      String randomid=UUID.randomUUID().toString(); 
      OutputStream os=ftpClient.storeFileStream(randomid+"-"+preferences.getStudentId()+".mp4"); 


      byte data[] = new byte[1024]; 
      long total = 0; 
      int count; 
      while ((count = progressInput.read(data)) != -1) { 
       total += count; 
       publishProgress((int) (total * 100/videoFileSize)); 
       os.write(data, 0, count); 
      } 

      os.flush(); 
      os.close(); 
      progressInput.close(); 
      buffIn.close(); 

      } 
      catch(IOException e) 
      { 
       e.printStackTrace(); 

      } 
      return null; 
     } 
     @Override 
     protected void onPreExecute() 
     { 
      super.onPreExecute(); 
      dialog.show(); 
     } 

     @Override 
     protected void onPostExecute(String result) 
     { 
      // TODO Auto-generated method stub 
      super.onPostExecute(result); 

     } 
    }

您可以使用一个名为SimpleFTP库。将simpleftp.jar添加到您的类路径中，并在需要时将其导入。

import org.jibble.simpleftp.*; 

try 
{ 
    SimpleFTP ftp = new SimpleFTP(); 

    // Connect to an FTP server on port 37. 
    ftp.connect("ftp.someurl.net", 37, "username", "password"); 

    // Set binary mode(used to prevent file corruption etc) 
    ftp.bin(); 

    // Change to a new working directory on the FTP server. 
    ftp.cwd("mywebdir"); 

    // Upload some files. 
    ftp.stor(new File("pic1.png")); 
    ftp.stor(new File("pic2.png")); 
    ftp.stor(new File("pic3.png")); 

    // or use an InputStream like so: 
    ftp.stor(new FileInputStream(new File("file1.png")), "file1.png"); 
    ftp.stor(mySocket.getInputStream(), "file2.png"); 

    // disconnect from the FTP server. 
    ftp.disconnect(); 
} 
catch (IOException e) 
{ 
    e.printStackTrace(); 
}
