我正在尝试使用代码在 FTP 服务器上上传文件
try {
FTPClient ftpClient = new FTPClient();
ftpClient.connect(host);
int reply = ftpClient.getReplyCode();
if (FTPReply.isPositiveCompletion(reply)) {
ftpClient.enterLocalPassiveMode();
boolean login = ftpClient.login(user, password);
if (login) {
File localFile = new File(fileName);
InputStream inputStream = new FileInputStream(localFile);
ftpClient.appendFile("/folder/output.txt", inputStream);
}
}
} catch (Exception ioe) {
ioe.printStackTrace();
System.out.println("FTP client received network error");
}
但是,它不会在 FTP 服务器上上传任何内容,如果我删除该ftpClient.enterLocalPassiveMode();
行,它会上传一个空的 output.txt 文件。感谢任何会提供帮助的人。
