我试图从 ftp 服务器获取列表并遇到编码问题
FTPClient.listfiles(String path) 方法
如果路径包含非拉丁字符,它总是返回空数组。
(我也在 unicode 中使用带有 python 和 perl 脚本的服务器 - 并且没有这样的问题)
请帮助解决这个问题。
这种与调试输出连接的方法:
public static FTPClient ftpConnect(String host, String login, String password) throws IOException {
FTPClient ftp = new FTPClient();
FTPClientConfig config = new FTPClientConfig();
ftp.configure(config);
debug(ftp.getReplyString());
debug("Connected to " + host + ".");
ftp.connect(host);
debug(ftp.getReplyString());
debug("Set passive transfer mode");
ftp.enterLocalPassiveMode();
debug(ftp.getReplyString());
debug("Login to " + host + ".");
ftp.login(login, password);
debug(ftp.getReplyString());
int reply;
ftp.setControlEncoding("UTF-8");
ftp.setAutodetectUTF8(true);
ftp.setFileType(FTPClient.BINARY_FILE_TYPE);
debug("Set binary transfer mode");
debug(ftp.getReplyString());
debug("Buffer size = " + ftp.getBufferSize());
// After connection attempt, you should check the reply code to verify
// success.
reply = ftp.getReplyCode();
if (!FTPReply.isPositiveCompletion(reply)) {
ftp.disconnect();
debug("FTP server refused connection.");
throw new IOException("FTP server refused connection.");
}
return ftp;
}
这里连接输出:
Connected to ftp.server.com.
220 FTP Server
220 FTP Server
Login to ftp.server.com.
230 Login successful.
Set binary transfer mode
200 Switching to Binary mode.
Set passive transfer mode
200 Switching to Binary mode.
Buffer size = 1024
这里有一些例子:
String source = "/english_name/Новая_папка12"; // non_latin path
String escaped_source = StringEscapeUtils.escapeJava(source);
FTPFile[] file_list = ftp.listFiles(escaped_source); // empty
file_list = ftp.listFiles(escaped_source + '/'); // empty
file_list = ftp.listFiles(source); // empty
file_list = ftp.listFiles('"' + source + '"'); // empty
file_list = ftp.listFiles(source + '/'); // empty
file_list = ftp.listFiles("/english_name"); // ok, but its another path
