[英]Apache commons-net FTP - uploading file to Secure FTP IIS
I'm trying to upload large file (>100Mb) using Apache commons-net FTP library to Secure FTP Server IIS. 我正在尝试使用Apache commons-net FTP库将大文件(> 100Mb)上传到Secure FTP Server IIS。
Here is my code: 这是我的代码:
try{
ftpClient = new FTPSClient("TLS", false);
this.ftpClient.setDataTimeout(6000000);
this.ftpClient.setConnectTimeout(6000000);
ftpClient.connect(host, port);
ftpClient.login(userName, password);
ftpClient.enterLocalPassiveMode();
if (ftpClient.getReplyCode() == 230){
ftpClient.sendCommand("OPTS UTF8 ON");
ftpClient.execPBSZ(0);
ftpClient.execPROT("P");
else{
throw new Exception("connection failed.....");}
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
InputStream is= new FileInputStream("C:\\movie.avi");
ftpClient.setUseEPSVwithIPv4(true);
ftpClient.storeFile(remotePath, is);
is.close();
}
catch (SocketException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
It fails to upload files larger then 19Mb. 无法上传大于19Mb的文件。 storeFile methods throws
IOException
with empty StackTrace. storeFile方法使用空StackTrace引发
IOException
。 You can see below IOException
variables: 您可以在下面看到
IOException
变量:
e CopyStreamException (id=39)
cause CopyStreamException (id=39)
detailMessage "IOException caught while copying." (id=45)
ioException SocketException (id=46)
cause SocketException (id=46)
detailMessage "Connection reset by peer: socket write error" (id=50)
stackTrace null
stackTrace null
totalBytesTransferred 19084288
Actually it behaves the following way: 实际上,它的行为方式如下:
1) when I'm starting upload, zero size file created, while I'm uploading file size is still zero and when the exception occurs, this empty file removed by FTP. 1)当我开始上传时,创建的文件大小为零,而我上传的文件大小仍为零,并且当发生异常时,此空文件被FTP删除。
2) funny thing is that FileZila fails to upload these files as well, but its limit size is 70Mb. 2)有趣的是FileZila也无法上传这些文件,但其限制大小为70Mb。
Am I missing something? 我想念什么吗?
Well. 好。 Sad by true, the problem caused by firewall, which closed Data port after 5 minutes time out.
真遗憾,这是防火墙引起的问题,防火墙在5分钟超时后关闭了数据端口。
