在 Android 上使用 FTP 上传图像

Question

如何在 Android 上使用 FTP 上传图片？

Answer 1

使用 SimpleFTP，只需将 simpleftp.jar 添加到您的类路径并将包导入任何将使用它的类中：Download here

import org.jibble.simpleftp.*;

上传图片等时请确保使用二进制模式，否则可能会损坏。

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();
}

这是所有功能，所以它不允许您下载文件！

Answer 2

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();
    }

}

这肯定会奏效。我已经做过很多次了。
