我试图让从FTP服务器 列表,并与的Java FTPClient listFiles返回空结果使用Unicode路径
FTPClient.listfiles(字符串路径)方法具有编码问题
它总是返回空数组,如果路径具有非拉丁字符。
(我也使用与Python和Perl脚本也以Unicode服务器 - 有这样的问题还没有)
请帮助解决这个问题。
这种方法对于调试输出连接:
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
这里是一些例子:
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
我面临同样的问题。请你帮我.. – Naveen
