无法在android中的FTP服务器上传文件

我正在尝试像这样上传文件

try { String extStorageDirectory = Environment.getExternalStorageDirectory().toString FTPClient ftpClient = new FTPClient(); ftpClient.connect("xxx.xxx.xx.xx"); if (FTPReply.isPositiveCompletion(ftpClient.getReplyCode())) { boolean status=ftpClient.login("username", "password"); Log.d(TAG, "login status=="+status); status=ftpClient.changeWorkingDirectory("New directory"); Log.d(TAG, "changeWorkingDirectory status=="+status); status=ftpClient.setFileType(FTP.BINARY_FILE_TYPE); Log.d(TAG, "setFileType status=="+status); ftpClient.enterLocalPassiveMode(); String srcFilePath=extStorageDirectory + "/AA.txt"; FileInputStream srcFileStream = new FileInputStream(new File(srcFilePath)); status=ftpClient.storeFile("AA.txt", srcFileStream); Log.d(TAG, "upload status=="+status); ftpClient.logout(); ftpClient.disconnect(); } else { Log.d(TAG, "connectfail"); } } catch (SocketException e) { Log.d(TAG, "SocketException status=="+e.toString()); e.printStackTrace(); } catch (FileNotFoundException e) { Log.d(TAG, "FileNotFoundException status=="+e.toString()); e.printStackTrace(); } catch (IOException e) { Log.d(TAG, "IOException status=="+e.toString()); e.printStackTrace(); } 

下面是我的logcat状态

 07-11 12:24:43.359: D/FTPDownloadDroid(10647): com.ss.dr 138 login status==true 07-11 12:24:48.379: D/FTPDownloadDroid(10647): com.ss.dr 141 changeWorkingDirectory status==true 07-11 12:24:48.859: D/FTPDownloadDroid(10647): com.ss.dr 143 setFileType status==tr 07-11 12:24:54.359: D/FTPDownloadDroid(10647): com.ss.dr 150 upload status==false 

我想在“新目录 ”文件夹和文件名AA.txt **上传文件，但它上传状态为false 。**

是服务器还是我的代码中的问题??? 请帮忙！！！！！！！！！ 提前致谢

试试下面的代码，我用这个来上传和下载服务器上的一首歌 。 我正在使用Apache的常用库。

请在下面的代码中对目录和文件名进行更改。

上传：

 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(); } } 

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(); } }
