問題描述

由此下載的文件，大小幾乎相同，但某些行不同.每個答案都指向二進制文件類型.但這無濟于事.有人知道這個問題(傳輸 PDF)嗎?

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();
}

推薦答案

使用包含空格的非轉(zhuǎn)義路徑時似乎會發(fā)生這種情況.例如.C:/Documents and Settings/測試

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

現(xiàn)在通過對空格使用轉(zhuǎn)義路徑解決了這個問題.感謝您的幫助

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