当我尝试将文件上传到 ftp 服务器时,出现错误。该服务器是远程服务器,但它提供 ftp 访问。这是我正在使用的代码

package fileuploaddemo;
import org.apache.commons.net.ftp.FTPClient;
import java.io.FileInputStream;
import java.io.IOException;
public class FileUploadDemo {
public static void main(String[] args) {
FTPClient client = new FTPClient();
FileInputStream fis = null;
try {
client.connect("ftp.adress.comlu.com");
client.login("username", "mypass");
//
// Create an InputStream of the file to be uploaded
//
String filename = "D:/xxx/screen0.png";
fis = new FileInputStream(filename);
//
// Store file to server
//
client.storeFile(filename, fis);
client.logout();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (fis != null) {
fis.close();
}
client.disconnect();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
这是程序输出。什么都没有上传,我得到的只是这些行。
