的URLConnection与FTPS

Question

是否有可能改变当前的源代码，所以我可以使用FTPS ?:

InputStream in = new URL(url).openStream(); 
OutputStream out = new  URL("ftp://"+user+":"+password+"@"+server+""+dir+""+filename_real_string).openConnection().get OutputStream(); 
byte[] buffer = new byte[16384]; 
while ((r=in.read(buffer))>=0) { 
    out.write(buffer, 0, r); 
} 
in.close(); 
out.close(); 

是否有可能没有任何额外的库或者如果没有，它库西服最好？

Answer 1

您可以使用：org.apache.commons.net.ftp.FTPSClient

用法示例：

public static void main(String[] args) { 
    FTPSClient ftp = new FTPSClient(); 
    String host = "server.com"; 
    int port = 2121; 
    String folderName = "dir"; 
    String username = "user"; 
    String password = "password"; 
    try { 
     ftp.connect(host, port); 
     ftp.login(username, password); 
     InputStream fis = new FileInputStream("../filename_src.txt"); 

     ftp.storeFile("/" + folderName + "/filename_dest.xml", fis); 
     fis.close(); 

     ftp.logout(); 
     ftp.disconnect(); 
    } catch (SocketException ex) { 
     Logger.getLogger(FTPSendMessage.class.getName()).log(Level.SEVERE, null, ex); 
    } catch (IOException ex) { 
     Logger.getLogger(FTPSendMessage.class.getName()).log(Level.SEVERE, null, ex); 
    } 
}
