使用 Apache Commons Net 下载后 FTP 文件损坏

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

使用包含空格的非转义路径时似乎会发生这种情况.例如.C:/Documents and Settings/测试
