获取“无法打开与端口xxxx的数据连接".从Windows批处理文件将文件上传到FTP时 [英] Getting "Could not open data connection to port xxxx" when uploading file to FTP from Windows batch file
问题描述
我正在尝试使用批处理文件将文本文件上传到FTP服务器.它成功登录并显示
I am trying to upload a text file to FTP server using a batch file. It logins successfully and shows
端口命令发送成功
Port command sent successfully
但随后显示
无法打开与端口xxxx的数据连接
连接超时
Could not open data connection to port xxxx
Connection timed out
这是批处理脚本:
@echo off
for %%A in (*.csv) do set latest=%%A
echo Latest file is %latest%
echo MYUSERNAME> upload.txt
echo MYPASSWORD>> upload.txt
echo asc>>upload.txt
echo put %latest% s.txt>> upload.txt
echo quit >> upload.txt
ftp -s:upload.txt server58.hostinger.in
推荐答案
这似乎是FTP活动模式的典型问题.服务器无法连接回您的计算机以建立数据传输连接.
This looks like a typical problem with an FTP active mode. The server cannot connect back to your machine to establish a data transfer connection.
这种情况通常发生，因为当今大多数客户端计算机都位于防火墙或NAT或两者之后，这导致FTP主动模式无法正常工作.要使活动模式正常工作，您需要打开防火墙(不推荐)和/或配置NAT路由规则.
That typically happens as nowadays most client machines are behind a firewall or NAT or both, what prevents the FTP active mode from working. To make the active mode working you need to open your firewall (not recommended) and/or configure NAT routing rules.
请参见 FTP模式和将网络配置为活动模式的文章.
或者您使用被动FTP模式.但是，Windows ftp.exe客户端不支持被动模式，这使它在今天变得毫无用处.
Or you use a passive FTP mode. The Windows ftp.exe client does not support the passive mode though, what makes it pretty useless nowadays.
因此，您需要使用另一个命令行FTP客户端.大多数FTP客户端都支持被动模式.
So you need to use another command-line FTP client. A majority of FTP clients do support the passive mode.
例如，使用 WinSCP ，您的批处理文件将是:
For example with WinSCP your batch file would be like:
@echo off
for %%A in (*.csv) do set latest=%%A
echo Latest file is %latest%
winscp.com /command ^
"open ftp://MYUSERNAME:MYPASSWORD@server58.hostinger.in/" ^
"put -transfer=ascii %latest% s.txt" ^
"exit"
请注意，WinSCP默认为被动模式.
Note that WinSCP defaults to the passive mode.
有关详细信息，请参见WinSCP指南:
