在Android上通过FTP上传图像

Question

如何在Android上使用FTP上传图像？

Answer 1

使用SimpleFTP，只需添加simpleftp.jar到类路径，并导入哪个类将使用它的包：Download here

import org.jibble.simpleftp.*; 

确保你上传图片和诸如此类时使用二进制模式，或者他们可能会成为损坏。

try 
{ 
    SimpleFTP ftp = new SimpleFTP(); 

    // Connect to an FTP server on port 21. 
    ftp.connect("ftp.somewhere.net", 21, "username", "password"); 

    // Set binary mode. 
    ftp.bin(); 

    // Change to a new working directory on the FTP server. 
    ftp.cwd("web"); 

    // Upload some files. 
    ftp.stor(new File("webcam.jpg")); 
    ftp.stor(new File("comicbot-latest.png")); 

    // You can also upload from an InputStream, e.g. 
    ftp.stor(new FileInputStream(new File("test.png")), "test.png"); 
    ftp.stor(someSocket.getInputStream(), "blah.dat"); 

    // Quit from the FTP server. 
    ftp.disconnect(); 
} 
catch (IOException e) 
{ 
    e.printStackTrace(); 
} 

这是所有的功能，所以它不会让你下载文件！

下载FTP Jar Library from Here

public void sendFileViaFTP() { 

    FTPClient ftpClient = null; 

    try { 
     ftpClient = new FTPClient(); 
     ftpClient.connect(InetAddress.getByName("ftp.myserver.com")); 

     if (ftpClient.login("myftpusername", "myftppass")) { 

      ftpClient.enterLocalPassiveMode(); // important! 
      ftpClient.setFileType(FTP.BINARY_FILE_TYPE); 
      String Location = Environment.getExternalStorageDirectory() 
        .toString(); 
      String data = Location + File.separator + "FileToSend.txt"; 
      FileInputStream in = new FileInputStream(new File(data)); 
      boolean result = ftpClient.storeFile("FileToSend.txt", in); 
      in.close(); 
      if (result) 
       Log.v("upload result", "succeeded"); 
      ftpClient.logout(); 
      ftpClient.disconnect(); 

     } 
    } catch (Exception e) { 
     Log.v("count", "error"); 
     e.printStackTrace(); 
    } 

} 

这将肯定工作。我做了很多次。
