Question

我试图将图像从Android上传到ftp服务器，但是当我尝试打开我上传的图像时，我看到以下消息而不是图像＆＃34;图像无法显示，因为它包含错误＆＃34;

这是我使用的代码

    public void uploadImage(String path){

     String server = "www.domainname.com";
        int port = 21;
        String user = "ftp-username";
        String pass = "ftp-password";

    FTPClient ftpClient = new FTPClient();
    try {

        ftpClient.connect(server, port);
        ftpClient.login(user, pass);
        ftpClient.enterLocalPassiveMode();


        ftpClient.setFileType(FTP.BINARY_FILE_TYPE);

        // APPROACH #1: uploads first file using an InputStream
        File firstLocalFile = new File(path);

        long fileSize = firstLocalFile.length();

        Log.i("File Size",fileSize+"");

        String firstRemoteFile = "testfile1.jpg";
        InputStream inputStream = new FileInputStream(firstLocalFile);

        Log.i("uploading", "Start uploading first file");
        boolean done = ftpClient.storeFile(firstRemoteFile, inputStream);
        inputStream.close();
        if (done) {
            Log.i("uploaded", "finished uploading first file");
        }

        // APPROACH #2: uploads second file using an OutputStream
        File secondLocalFile = new File(path);
        String secondRemoteFile = "testfile2.jpg";
        inputStream = new FileInputStream(secondLocalFile);

        Log.i("uploading", "Start uploading second file");
        OutputStream outputStream = ftpClient.storeFileStream(secondRemoteFile);
        byte[] bytesIn = new byte[4096];
        int read = 0;

        while ((read = inputStream.read(bytesIn)) != -1) {
            outputStream.write(bytesIn, 0, read);
        }
        inputStream.close();
        outputStream.close();

        boolean completed = ftpClient.completePendingCommand();
        if (completed) {
            Log.i("uploaded", "finished uploading second file");
        }

    } catch (IOException ex) {
        Log.i("Error", "Error: " + ex.getMessage());
        ex.printStackTrace();
    } finally {
        try {
            if (ftpClient.isConnected()) {
                ftpClient.logout();
                ftpClient.disconnect();
            }
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
}

错误在哪里!!？

提前致谢..

这看起来很像这个错误：FTPClient corrupts the images while uploading to ftp server on android?

请尝试使用FTP4J。
