如何在windows ftp脚本中捕获错误条件？ [英] how to capture error conditions in windows ftp scripts?

问题描述

我使用windows批处理脚本自动运行ftp脚本。

I am using windows batch scripts to run ftp scripts automatically. Where the set of ftp commands I want run is saved in a file.

例子：

@echo off 
ftp -n -i -s:c:\temp\myftpscriptfile.ftp

我已使用％ERRORLEVEL％语法成功捕获批处理命令中的错误条件。我的挑战是，即使脚本内的命令失败，ftp脚本命令始终返回0的ERRORLEVEL。

I have used the %ERRORLEVEL% syntax to successfully capture error conditions in the batch commands. My challenge is the ftp script command is always returning an ERRORLEVEL of 0 even when the commands inside the script fail.

我很难弄清楚如何使用ftp脚本实际上在内部发生错误时会返回或陷入陷阱。它会简单地通过命令盲目运行，即使我可以看到屏幕上回显的错误，我无法捕获它们作为ERRORLEVEL ..

I am having difficulty figuring out how to have the ftp script actually return or trap when errors occur inside it. It will simply run through the commands blindly and even though i can see the errors echoed on screen I can't capture them as an ERRORLEVEL..

尝试屏幕截图的尝试脚本无法登录，然后回显显示零的ERRORLEVEL ..

Sample screen shot of trying script which fails to login and then echoing the ERRORLEVEL which shows a zero..

ftp> open fubar.test.com
Unknown host fubar.test.com
ftp> user test test
Not connected.
ftp> ascii
Not connected.
ftp> cd /home/test/dirname
Not connected.
ftp> mput C:\Test\test*.txt
Not connected.
ftp> close
Not connected.
ftp> quit
.0

推荐答案

解析 ftp 使用为/ F 命令进行通信。下一个脚本中的可能方法。警告：假设存在一些未包含在给定测试序列中的 ftp 错误消息。当然，您可以测试正面 ftp 消息，而不是...

Parse ftp communication using for /F command. Possible approach in next script. Caveat: there supposedly exist some ftp error message(s) not included in given test sequence. Of course, you can test positive ftp messages rather...

@ECHO OFF >NUL
SETLOCAL enableextensions enabledelayedexpansion
set "errsftp=0"
ftp -n -i -s:c:\temp\myftpscriptfile.ftp >c:\temp\31442020.err 2>&1
for /F "tokens=1*" %%G in (c:\temp\31442020.err) do (
  rem echo %%G [%%H]
  if "%%G"=="ftp>" (
    set "line=%%H"
    set "errs=0"
  ) else (
    set "reply=%%G %%H"
    Call :testreply Unknown host
    Call :testreply Connection timed out
    Call :testreply Not connected
    rem insert next tests here
    if !errs! EQU 0 echo !line! =looks OK= !reply!
  )
)
echo(
echo :errors total: %errsftp%

ENDLOCAL
goto :eof

:testreply
    set "ylper=!reply:%*=!"
    if not "!ylper!"=="!reply!" (
      echo !line! =ERROR= !reply!
      set /A "errs+=1"
      set /A "errsftp+=1"
    )
goto :eof
