【中文标题】从安卓手机上传文件到FTP服务器？【英文标题】：Uploading a file to a FTP server from android phone? 【发布时间】：2012-07-21 00:10:47 【问题描述】：以下是用于创建文本文档并将其上传到我的 FTP 服务器的代码。由于某种原因，它似乎不起作用。我习惯了
提供的库http://lavalatwork.blogspot.tw/2010/09/using-apache-commons-ftp-library-in.html
用于与 FTP 服务器通信。
try
final String testString = new String("Hello");
FileOutputStream fOut = openFileOutput("samplefile.txt",
MODE_WORLD_READABLE);
OutputStreamWriter osw = new OutputStreamWriter(fOut);
osw.write(testString);
osw.flush();
osw.close();
catch(IOException ex)
FTPClient mFTP = new FTPClient();
try
// Connect to FTP Server
mFTP.connect("192.168.10.101");
//mFTP.login("user", "password");
mFTP.setFileType(FTP.BINARY_FILE_TYPE);
mFTP.enterLocalPassiveMode();
// Prepare file to be uploaded to FTP Server
File file = new File(getFileStreamPath("samplefile.txt")+ "");
FileInputStream ifile = new FileInputStream(file);
// Upload file to FTP Server
mFTP.storeFile("filetotranfer",ifile);
mFTP.disconnect();
catch (SocketException e)
// TODO Auto-generated catch block
e.printStackTrace();
catch (IOException e)
// TODO Auto-generated catch block
e.printStackTrace();
任何帮助将不胜感激。
【问题讨论】：
在使用 Apache Commons FTP 客户端时检查 logcat 的输出通常很有帮助。 请明确说明什么是行不通的。并发布您的 logcat。 【参考方案1】：看到这个......这将帮助您纠正代码中的问题。
我已使用 apache 的公共库向服务器上传和下载音频文件...请参阅此...
上传中：
public void goforIt()
FTPClient con = null;
try
con = new FTPClient();
con.connect("192.168.2.57");
if (con.login("Administrator", "KUjWbk"))
con.enterLocalPassiveMode(); // important!
con.setFileType(FTP.BINARY_FILE_TYPE);
String data = "/sdcard/vivekm4a.m4a";
FileInputStream in = new FileInputStream(new File(data));
boolean result = con.storeFile("/vivekm4a.m4a", in);
in.close();
if (result) Log.v("upload result", "succeeded");
con.logout();
con.disconnect();
catch (Exception e)
e.printStackTrace();
正在下载：
public void goforIt()
FTPClient con = null;
try
con = new FTPClient();
con.connect("192.168.2.57");
if (con.login("Administrator", "KUjWbk"))
con.enterLocalPassiveMode(); // important!
con.setFileType(FTP.BINARY_FILE_TYPE);
String data = "/sdcard/vivekm4a.m4a";
OutputStream out = new FileOutputStream(new File(data));
boolean result = con.retrieveFile("vivekm4a.m4a", out);
out.close();
if (result) Log.v("download result", "succeeded");
con.logout();
con.disconnect();
catch (Exception e)
Log.v("download result","failed");
e.printStackTrace();

【参考方案2】：您可以使用Simple Java FTP Client并将其添加为项目的外部jar，您也可以参考这个link
public class FileUpload
/**
* Upload a file to a FTP server. A FTP URL is generated with the
* following syntax:
* ftp://user:password@host:port/filePath;type=i.
*
* @param ftpServer , FTP server address (optional port ':portNumber').
* @param user , Optional user name to login.
* @param password , Optional password for user.
* @param fileName , Destination file name on FTP server (with optional
* preceding relative path, e.g. "myDir/myFile.txt").
* @param source , Source file to upload.
* @throws MalformedURLException, IOException on error.
*/
public void upload( String ftpServer, String user, String password,
String fileName, File source ) throws MalformedURLException,
IOException
if (ftpServer != null && fileName != null && source != null)
StringBuffer sb = new StringBuffer( "ftp://" );
// check for authentication else assume its anonymous access.
if (user != null && password != null)
sb.append( user );
sb.append( ':' );
sb.append( password );
sb.append( '@' );
sb.append( ftpServer );
sb.append( '/' );
sb.append( fileName );
/*
* type ==> a=ASCII mode, i=image (binary) mode, d= file directory
* listing
*/
sb.append( ";type=i" );
BufferedInputStream bis = null;
BufferedOutputStream bos = null;
try
URL url = new URL( sb.toString() );
URLConnection urlc = url.openConnection();
bos = new BufferedOutputStream( urlc.getOutputStream() );
bis = new BufferedInputStream( new FileInputStream( source ) );
int i;
// read byte by byte until end of stream
while ((i = bis.read()) != -1)
bos.write( i );
finally
if (bis != null)
try
bis.close();
catch (IOException ioe)
ioe.printStackTrace();
if (bos != null)
try
bos.close();
catch (IOException ioe)
ioe.printStackTrace();
else
System.out.println( "Input not available." );
你也可以使用Apache commons-net-ftp库，更多细节可以关注这个link。
import org.apache.commons.net.ftp.FTPClient;
FTPClient ftpClient = new FTPClient();
try
ftpClient.connect(InetAddress.getByName(SERVER));
ftpClient.login(USERNAME, PASSWORD);
ftpClient.changeWorkingDirectory(PATH);
if (ftpClient.getReplyString().contains("250"))
ftpClient.setFileType(org.apache.commons.net.ftp.FTP.BINARY_FILE_TYPE);
BufferedInputStream buffIn = null;
buffIn = new BufferedInputStream(new FileInputStream(FULL_PATH_TO_LOCAL_FILE));
ftpClient.enterLocalPassiveMode();
ProgressInputStream progressInput = new ProgressInputStream(buffIn, progressHandler);
boolean result = ftpClient.storeFile(localAsset.getFileName(), progressInput);
buffIn.close();
ftpClient.logout();
ftpClient.disconnect();
catch (SocketException e)
Log.e(SorensonApplication.TAG, e.getStackTrace().toString());
catch (UnknownHostException e)
Log.e(SorensonApplication.TAG, e.getStackTrace().toString());
catch (IOException e)
Log.e(SorensonApplication.TAG, e.getStackTrace().toString());
【讨论】：
我们是否应该在 Manifest 上设置一些东西以获得互联网连接权限？ 出现someSocket问题，是什么意思？【参考方案3】：这里是代码块：
private class UploadFile extends AsyncTask<String, Integer, Boolean>
@Override
protected Boolean doInBackground(String... params)
FTPClient client = new FTPClient();
try
client.connect(params[1], PORT);
client.login(params[2], params[3]);
client.setFileType(FTP.BINARY_FILE_TYPE, FTP.BINARY_FILE_TYPE);
return client.storeFile(filename, new FileInputStream(new File(
params[0])));
catch (Exception e)
Log.d("FTP", e.toString());
return false;
@Override
protected void onPostExecute(Boolean sucess)
if (sucess)
Toast.makeText(activity, "File Sent", Toast.LENGTH_LONG).show();
else
Toast.makeText(activity, "Error", Toast.LENGTH_LONG).show();
请获取完整的工作项目，用于从以下驱动器将文件上传到 FTP 服务器。
文件上传到 FTP 使用 PORT 21， 在 FTP 上上传文件所需的参数..
