在FtpClient中用ftp FTP命令建自己要用的东东。。

由于sun没有公开FtpClient的API所以我们將就使用Sun的未公开类别暫時應急一下，方法命名大多與Common net ftpClient 雷同，不足的只好用issueCommand自己丟FTP命令：

 

import java.io.FileNotFoundException;

import java.io.IOException;

import java.net.Proxy;

import sun.net.TelnetInputStream;

import sun.net.TelnetOutputStream;

import sun.net.ftp.FtpClient;

public class SundFtpClient extends FtpClient {

  public static final int   ASCII_FILE_TYPE =0;

  public static final int   BINARY_FILE_TYPE=2;

  public SundFtpClient(String host) throws IOException {

    super(host);

  }

  public SundFtpClient(String host, int port) throws IOException {

    super(host, port);

  }

  public int issueCommand(java.lang.String cmd) throws IOException{

    return super.issueCommand(cmd);

  }

  public void issueCommandCheck(java.lang.String cmd) throws IOException{

    super.issueCommandCheck(cmd);

  }

  public boolean setFileType(int fileType)throws IOException{

    if(fileType==ASCII_FILE_TYPE){

      return issueCommand("TYPE A")==1;

    }else{

      return issueCommand("TYPE B")==1;

    }

  }

  public void enterLocalPassiveMode(){

    try{

      issueCommand("PASV");

    }catch(IOException e){}

  }

  public boolean isConnected(){

    return this.serverIsOpen();

  }

  public void connect(java.lang.String hostname)throws java.io.IOException{

    this.disconnect();

    this.openServer(hostname);

  }

  public void connect(java.lang.String hostname,int port)throws java.io.IOException{

    this.disconnect();

    this.openServer(hostname,port);

  }

  public void disconnect()throws java.io.IOException{

    if(this.serverIsOpen())

      this.closeServer();

  }

  public boolean deleteFile(String pathname)throws java.io.IOException{

    try{

      return issueCommand("DELE "+pathname)==1;

    }catch(FileNotFoundException e){

      return false;

    }

  }

  public boolean makeDirectory(String pathname)throws java.io.IOException{

    try{

      return issueCommand("MKD "+pathname)==1;

    }catch(FileNotFoundException e){

      return false;

    }

  }

  public boolean removeDirectory(String pathname)throws java.io.IOException{

    try{

      return issueCommand("RMD "+pathname)==1;

    }catch(FileNotFoundException e){

      return false;

    }

  }

  public boolean sendNoOp()throws java.io.IOException{

    return issueCommand("NOOP")==1;

  }

  public String printWorkingDirectory()throws java.io.IOException{

    return super.pwd();

  }

  public boolean changeToParentDirectory()throws java.io.IOException{

    return issueCommand("CDUP")==1;

  }

  public boolean changeWorkingDirectory(String pathname)throws java.io.IOException{

    try{

      return issueCommand("CWD "+pathname)==1;

    }catch(FileNotFoundException e){

      return false;

    }

  }

  public void storeFile(String remote,java.io.InputStream local)throws java.io.IOException{

    byte[] buf = new byte[1024];

    int readed=0;

    TelnetOutputStream outs = this.put(remote);

    synchronized (local) {

     while((readed=local.read(buf,0,1024))>0)

        outs.write(buf,0,readed);

      outs.flush();

      outs.close();

      local.close();

    }

  }

  public void retrieveFile(String remote,java.io.OutputStream local)throws java.io.IOException{

    byte[] buf = new byte[1024];

    int readed=0;

    TelnetInputStream ins = this.get(remote);

    synchronized (local) {

      while((readed=ins.read(buf,0,1024))>0)

        local.write(buf,0,readed);

      local.flush();

      local.close();

      ins.close();

    }

  }

}
