Question

我正在使用File Transfer Protocol使用工具 WinSCP 将文件从一台服务器传输到另一台服务器，每种类型的文件都有一个单独的目录要存储，因此在传输之前，我必须创建该目录。但是，当第二次传输相同类型的文件时，它失败了，因为已经存在具有相同名称的目录。

两台服务器均使用 Windows操作系统，因此我正在创建一个批处理文件以传输文件，批处理代码如下：-

@echo off

set user=%1
set type=%2
set input=D:\path\to\files\%user%\%type%\*.*


"WinSCP.com" ^
  /log="D:\path\to\log\WinSCP.log" /ini=nul ^
  /command ^
    "open ftp://users:passwords@127.0.0.1/" ^
    "mkdir %user%" ^
    "cd %user%" ^
    "mkdir %type%" ^
    "cd %type%" ^
    "put %input%" ^
    "exit"

set WINSCP_RESULT=%ERRORLEVEL%

if %WINSCP_RESULT% equ 0 (
  echo Success
) else (
  echo Error
)

exit /b %WINSCP_RESULT%

这是WinSCP.log：-
