Am using the above code to upload a file named "data.doc" in the server location 192.168.0.210. The destination location of my server is fileserver/filesbackup/Emac/.
我正在使用上面的代码在服务器位置 192.168.0.210 上传一个名为“data.doc”的文件。我的服务器的目标位置是 fileserver/filesbackup/Emac/。
But I end up receiving the error "553 Could not create file" although the server gets connected successfully. I suspect that I am giving the destination format in a wrong way. Kindly let me know what has to be done to resolve the issue?
但我最终收到错误“553 无法创建文件”，尽管服务器已成功连接。我怀疑我以错误的方式提供了目标格式。请让我知道必须采取什么措施才能解决问题？
回答by Roland Illig
The problem is that you try to upload the file to a directory. You should rather specifiy the destination filename, not the destination directory.
问题是您尝试将文件上传到目录。您应该指定目标文件名，而不是目标目录。
Does it work when you try the same in another FTP client?
当您在另一个 FTP 客户端中尝试相同时，它是否有效？

[更新]
Here is some (untested, since I don't have an FTP server) code that does the error handling better and in a shorter form.
这里有一些（未经测试，因为我没有 FTP 服务器）代码可以更好地以更短的形式处理错误。
package so3972768;

import java.io.IOException;
import java.io.InputStream;
import org.apache.commons.net.ftp.FTPClient;

private static void check(FTPClient ftp, String cmd, boolean succeeded) throws IOException {
if (!succeeded) {
throw new IOException("FTP error: " + ftp.getReplyString());
}
}
private static String today() {
return new SimpleDateFormat("yyyy-MM-dd").format(new Date());
}
public void uploadfile(String server, String username, String Password, String sourcePath, String destDir) throws IOException {
FTPClient ftp = new FTPClient();
ftp.connect(server);
try {
check(ftp, "login", ftp.login(username, Password));
System.out.println("Connected to " + server + ".");
InputStream input = new FileInputStream(sourcePath);
try {
String destination = destDir;
if (destination.endsWith("/")) {
destination += today() + "-" + new File(sourcePath).getName();
}
check(ftp, "store", ftp.storeFile(destination, input));
System.out.println("Stored " + sourcePath + " to " + destination + ".");
} finally {

}
check(ftp, "logout", ftp.logout());
} finally {

}
