推荐答案
我认为 Windows ftp.exe 没有可靠的方法.
I do not think there's a reliable way to do this with Windows ftp.exe.
无论连接成功还是之前的命令成功，它都会盲目地继续运行命令.
It blindly keeps running the commands, no matter if connection or previous commands succeeded.
它甚至不会通过退出代码报告结果.
It won't even report the result via exit code.
您所能做的就是解析 ftp.exe 输出.
All you can do is to parse the ftp.exe output.
您最好使用第 3 方 FTP 客户端.
You should better use a 3rd-party FTP client.
例如，您可以使用 WinSCP 脚本:
@echo off
winscp.com /log=ftp.log /command ^
"open ftp://user:password@example.com/" ^
"put c:localpathfile.txt" ^
"exit"
如果连接(open 命令)失败，WinSCP 获胜'不执行以下命令(put).
If connection (the open command) fails, WinSCP won't execute the following commands (the put).
