Java FTP上传会创建一个空文件 [英] Java FTP upload creates an empty file
问题描述
当我尝试使用Apache Commons FTPClient
和以下代码上传简单文本文件时:
When I try to upload a simple text file with the Apache Commons FTPClient
and this code:
FTPClient ftp = new FTPClient();
int reply;
// connect
try {
ftp.connect(serverAdd);
ftp.login(username,password);
reply = ftp.getReplyCode();
if(FTPReply.isPositiveCompletion(reply)){
System.out.println("Connected Success..");
// upload file
try {
String fileDir = "testfile.txt";
FileInputStream in = null;
in = new FileInputStream(fileDir);
ftp.storeFile(fileDir,in);
System.out.println("File upload complete..");
}catch(IOException e){
System.out.println(e);
}
ftp.disconnect();
System.out.println("Disconnected..");
}else {
System.out.println("Connection Failed..");
ftp.disconnect();
}
} catch (SocketException ex) {
ex.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
}
在FTP服务器的根目录中创建了一个文件,但该文件为空.怎么了?我已经尝试在上传PDF文件时将ftp模式更改为BINARY.但是文件的大小也为0.
A file gets created in the root of the FTP server but it is empty. What's wrong? I already tried to change the ftp mode to BINARY when uploading a PDF file. But the file is also 0 in size.
ftp.setFileType(FTP.BINARY_FILE_TYPE);
我也只想上传一堆txt文件,所以默认的ascii模式应该可以,对吧?
I also only want to upload a bunch of txt files, so the default ascii mode should be fine, right?
推荐答案
好的,看来这是我的防火墙的一个探查.当我停用防火墙时,文件将毫无问题地写入ftp.
ok, it seems that it is a probem with my firewall. when I deactivate the firewall the file gets written to the ftp with no problem.
