最近研究了一下在android端實現ftp server 功能,在網上搜了幾個,沒有能用的基本是各種抄襲,還是自己研究吧
首先到 apache官網下載ftp server 相關jar和設定檔,最新的是Apache FtpServer 1.0.6 Release版本
看一下:
由於是apache已經將ftp server相關的實現封裝的很好了,所以實現起來就簡單多了
匯入路徑\apache-ftpserver-1.0.6\common\lib下相關jar包
主要的jar包檔案
實現代碼:
package com.orgcent.ftp;import java.io.File;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import java.net.InetAddress;import java.net.NetworkInterface;import java.net.SocketException;import java.util.Enumeration;import org.apache.ftpserver.FtpServer;import org.apache.ftpserver.FtpServerFactory;import org.apache.ftpserver.ftplet.FtpException;import org.apache.ftpserver.listener.ListenerFactory;import org.apache.ftpserver.ssl.SslConfigurationFactory;import org.apache.ftpserver.usermanager.PropertiesUserManagerFactory;import android.app.Activity;import android.content.Context;import android.os.Bundle;import android.os.Environment;import android.util.Log;import android.widget.TextView;public class FtpServerActivity extends Activity {private FtpServer mFtpServer;private String ftpConfigDir= Environment.getExternalStorageDirectory().getAbsolutePath()+"/ftpConfig/";@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);TextView tv=(TextView)findViewById(R.id.tvText);String info="請通過瀏覽器或者我的電腦訪問以下地址\n"+"ftp://"+getLocalIpAddress()+":2221\n";tv.setText(info);File f=new File(ftpConfigDir);if(!f.exists())f.mkdir();copyResourceFile(R.raw.users, ftpConfigDir+"users.properties");Config1();} public String getLocalIpAddress() { String strIP=null; try { for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) { NetworkInterface intf = en.nextElement(); for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) { InetAddress inetAddress = enumIpAddr.nextElement(); if (!inetAddress.isLoopbackAddress()) { strIP= inetAddress.getHostAddress().toString(); } } } } catch (SocketException ex) { Log.e("msg", ex.toString()); } return strIP; } private void copyResourceFile(int rid, String targetFile){ InputStream fin = ((Context)this).getResources().openRawResource(rid); FileOutputStream fos=null; int length;try {fos = new FileOutputStream(targetFile);byte[] buffer = new byte[1024]; while( (length = fin.read(buffer)) != -1){ fos.write(buffer,0,length); }} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} finally{if(fin!=null){try {fin.close();} catch (IOException e) {e.printStackTrace();}} if(fos!=null){ try {fos.close();} catch (IOException e) {e.printStackTrace();} }} }void Config1(){//Now, let's configure the port on which the default listener waits for connections.FtpServerFactory serverFactory = new FtpServerFactory(); ListenerFactory factory = new ListenerFactory(); PropertiesUserManagerFactory userManagerFactory = new PropertiesUserManagerFactory();String[] str ={"mkdir", ftpConfigDir}; try { Process ps = Runtime.getRuntime().exec(str); try { ps.waitFor(); } catch (InterruptedException e) { e.printStackTrace(); } }catch (IOException e) { e.printStackTrace(); } String filename=ftpConfigDir+"users.properties";//"/sdcard/users.properties";File files=new File(filename);userManagerFactory.setFile(files); serverFactory.setUserManager(userManagerFactory.createUserManager());// set the port of the listenerfactory.setPort(2221);// replace the default listenerserverFactory.addListener("default", factory.createListener()); // start the serverFtpServer server = serverFactory.createServer(); this.mFtpServer = server; try {server.start();} catch (FtpException e) {e.printStackTrace();}}void Config2(){//Now, let's make it possible for a client to use FTPS (FTP over SSL) for the default listener.FtpServerFactory serverFactory = new FtpServerFactory(); ListenerFactory factory = new ListenerFactory(); // set the port of the listenerfactory.setPort(2221);// define SSL configurationSslConfigurationFactory ssl = new SslConfigurationFactory();ssl.setKeystoreFile(new File(ftpConfigDir+"ftpserver.jks"));ssl.setKeystorePassword("password");// set the SSL configuration for the listenerfactory.setSslConfiguration(ssl.createSslConfiguration());factory.setImplicitSsl(true);// replace the default listenerserverFactory.addListener("default", factory.createListener()); PropertiesUserManagerFactory userManagerFactory = new PropertiesUserManagerFactory();userManagerFactory.setFile(new File(ftpConfigDir+"users.properties")); serverFactory.setUserManager(userManagerFactory.createUserManager()); // start the serverFtpServer server = serverFactory.createServer(); this.mFtpServer = server; try {server.start();} catch (FtpException e) {e.printStackTrace();}}@Overrideprotected void onDestroy() {super.onDestroy();if(null != mFtpServer) {mFtpServer.stop();mFtpServer = null;}}}
最重要一步,設定檔修改
設定檔所在目錄:apache-ftpserver-1.0.6\res\conf
這裡我們主要使用users.properties設定檔,修改內容如下

最後別忘了相關許可權:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" > </uses-permission> <uses-permission android:name="android.permission.INTERNET" > </uses-permission> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" > </uses-permission> <uses-permission android:name="android.permission.READ_PHONE_STATE" > </uses-permission> <uses-permission android:name="android.permission.WAKE_LOCK" > </uses-permission> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" > </uses-permission>
ok,這樣簡單的就完成了android端ftp server 伺服器功能
