使用Apache Commons Net下载后FTP文件损坏 [英] FTP file corrupt after download with Apache Commons Net

问题描述

此文件下载的文件大小几乎相同，但某些行不同.每个答案都指向二进制文件类型.但这无济于事. 对这个问题有任何想法吗(传输PDF)?

The files downloaded by this, are nearly the same size but differ in some lines. Every answer points to binary file type. But this won't help. Got anybody an idea for the problem (transferring PDF)?

FTPClient ftpClient = new FTPClient();
OutputStream outputStream = null;
boolean resultOk = true;

try {
    ftpClient.connect(host, port);
    ftpClient.enterLocalPassiveMode();
    ftpClient.setFileTransferMode(FTP.COMPRESSED_TRANSFER_MODE);
    ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
    if (showMessages) {
        System.out.println(ftpClient.getReplyString());
    }
    resultOk &= ftpClient.login(usr, pwd);
    if (showMessages) {
        System.out.println(ftpClient.getReplyString());
    }

    outputStream = new FileOutputStream(localResultFile);
    resultOk &= ftpClient.retrieveFile(remoteSourceFile, outputStream);
    outputStream.flush();
    outputStream.close();

    if (showMessages) {
        System.out.println(ftpClient.getReplyString());
    }
    if (resultOk == true) {
        resultOk &= ftpClient.deleteFile(remoteSourceFile);
    }

    resultOk &= ftpClient.logout();
    if (showMessages) {
        System.out.println(ftpClient.getReplyString());
    }
} finally {

    ftpClient.disconnect();
}

推荐答案

使用包含空格的未转义路径时，似乎会发生这种情况.例如. C:/文档和设置/测试

It seems to happen when using unescaped paths that contain spaces. E.g. C:/Documents and Settings/test

现在通过对空格使用转义路径来解决该问题.谢谢您的帮助

Got it solved now by using a escaped path for the spaces. Thanks for your help
