使用FTP下载目录,即FTP命令批量自动下载的bat文件
人气:2想了解使用FTP下载目录,即FTP命令批量自动下载的bat文件的相关内容吗,在本文为您仔细讲解的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:使用FTP下载目录,即FTP命令批量自动下载的bat文件,下面大家一起来学习吧。
FTP不支持目录的下载,不过FTP命令提供了mget命令,允许多文件下载,但每下载一个文件都需要确认,不能自动完成。本文主要介绍使用批处理,结合FTP的相关命令来实现批量文件的下载,以便达到目录下载的目的。
大致想法如下:
ftp -s:filename hosts >result.txt 执行脚本,并将结果定向输出到result.txt
脚本内容,如
cd mydir
ls
bye
可以将mydir命令列出
然后使用批处理分析result.txt
从150 Opening ASCII mode data connection for file list.的下一行开始算,直到226 Transfer complete都是要下载的内容
然后用批处理加ftp脚本,使用get命令逐个下载
脚本内容,如
cd mydir
ls
bye

从150 Opening ASCII mode data connection for file list.的下一行开始算,直到226 Transfer complete都是要下载的内容
然后用批处理加ftp脚本,使用get命令逐个下载
但实际过程中发现,在FTP脚本中使用get有问题,提示参数错误,无法使用。

G:>ftp -?
Transfers files to and from a computer running an FTP server service
(sometimes called a daemon). Ftp can be used interactively.
FTP [-v] [-d] [-i] [-n] [-g] [-s:filename] [-a] [-w:windowsize] [-A] [host]
-v Suppresses display of remote server responses.
-n Suppresses auto-login upon initial connection.
-i Turns off interactive prompting during multiple file
transfers.
-d Enables debugging.
-g Disables filename globbing (see GLOB command).
-s:filename Specifies a text file containing FTP commands; the
commands will automatically run after FTP starts.
-a Use any local interface when binding data connection.
-A login as anonymous.
-w:buffersize Overrides the default transfer buffer size of 4096.
host Specifies the host name or IP address of the remote
host to connect to.
Notes:
- mget and mput commands take y/n/q for yes/no/quit.
- Use Control-C to abort commands.

发现 -i 参数可以去除mget的提示,经过测试,实现了如下脚本(使用了匿名登入,如果非匿名,可以修改登入脚本):
echo cd autoruns>ftp.txt
echo mget *>>ftp.txt
echo bye>>ftp.txt
ftp -i -A -s:ftp.txt 10.1.103.10
echo mget *>>ftp.txt
echo bye>>ftp.txt
ftp -i -A -s:ftp.txt 10.1.103.10
不过,这只是下载了目录中的文件,如果有子目录,那还需要用dir命令输出,并转向输出到文本,用find来提取目录,如:
echo cd autoruns>ftp.txt
echo dir>>ftp.txt
echo bye>>ftp.txt
ftp -A -s:ftp.txt 10.1.103.10 |find "<DIR>">result.txt
for /f "tokens=2,3*" %%i in (result.txt) do echo %%k
echo dir>>ftp.txt
echo bye>>ftp.txt
ftp -A -s:ftp.txt 10.1.103.10 |find "<DIR>">result.txt
for /f "tokens=2,3*" %%i in (result.txt) do echo %%k
如有子文件夹,那就要深入编写了。
经过编写测试,实现如下脚本,运行环境WINXP SP2,运行通过,未载其它系统上测试过:
1、主要脚本ftpget.bat,更改前4个变量的相关信息,该脚本调用makeTree.bat,请参见2
rem FTP服务器地址
set host=10.1.103.10
rem FTP登入名,如果匿名不用改
set user=anonymous
rem FTP登入密码,如果匿名不用改
set pass=123456
rem 需要下载的FTP目录,如果下载子目录以分格
set dirname=目录1子目录
set homedir=%cd%
rem 生成FTP目录结构
del tree.txt
start /w cmd /c makeTree %dirname% 0
del result*.txt
for /f "delims=/" %%i in (tree.txt) do (
rem 获取dirname的所有文件
rem =============================
cd %homedir%
md %%i
cd /d %%i
echo %user%>ftp.txt
echo %pass%>>ftp.txt
echo cd %%i>>ftp.txt
rem mget *.* 下载所有文件,但不能下载无扩展名的文件;
rem 如果使用mget * 可以下载所有文件,但会把子目录的文件也下载过来
echo mget *.*>>ftp.txt
echo bye>>ftp.txt
ftp -i -A -s:ftp.txt %host%
del ftp.txt
rem ==============================
)
cd %homedir%
del tree.txt
set host=10.1.103.10
rem FTP登入名,如果匿名不用改
set user=anonymous
rem FTP登入密码,如果匿名不用改
set pass=123456
rem 需要下载的FTP目录,如果下载子目录以分格
set dirname=目录1子目录
set homedir=%cd%
rem 生成FTP目录结构
del tree.txt
start /w cmd /c makeTree %dirname% 0
del result*.txt
for /f "delims=/" %%i in (tree.txt) do (
rem 获取dirname的所有文件
rem =============================
cd %homedir%
md %%i
cd /d %%i
echo %user%>ftp.txt
echo %pass%>>ftp.txt
echo cd %%i>>ftp.txt
rem mget *.* 下载所有文件,但不能下载无扩展名的文件;
rem 如果使用mget * 可以下载所有文件,但会把子目录的文件也下载过来
echo mget *.*>>ftp.txt
echo bye>>ftp.txt
ftp -i -A -s:ftp.txt %host%
del ftp.txt
rem ==============================
)
cd %homedir%
del tree.txt
2、maketree.bat,生成FTP目录树
rem 生成FTP目录结构
rem 调用方法 maketree dir1dir2 n (n>=1)
rem %1 == dir1dir2
rem %2 == n
set /a treetime=%2+1
echo %1 >>tree.txt
echo %user% >ftp%treetime%.txt
echo %pass% >>ftp%treetime%.txt
echo cd %1 >>ftp%treetime%.txt
echo dir >>ftp%treetime%.txt
echo bye >>ftp%treetime%.txt
ftp -A -s:ftp%treetime%.txt %host% |find "<DIR>">result%treetime%.txt
for /f "tokens=2,3*" %%i in (result%treetime%.txt) do (start /w cmd /c Maketree.bat %1%%k %treetime%)
del result%treetime%.txt
del ftp%treetime%.txt
rem 调用方法 maketree dir1dir2 n (n>=1)
rem %1 == dir1dir2
rem %2 == n
set /a treetime=%2+1
echo %1 >>tree.txt
echo %user% >ftp%treetime%.txt
echo %pass% >>ftp%treetime%.txt
echo cd %1 >>ftp%treetime%.txt
echo dir >>ftp%treetime%.txt
echo bye >>ftp%treetime%.txt
ftp -A -s:ftp%treetime%.txt %host% |find "<DIR>">result%treetime%.txt
for /f "tokens=2,3*" %%i in (result%treetime%.txt) do (start /w cmd /c Maketree.bat %1%%k %treetime%)
del result%treetime%.txt
del ftp%treetime%.txt
虽然已经实现,但仍然有小问题,就是mget *.* 不能下载无扩展名的程序;如果使用mget * 可以下载所有文件,但会把子目录的文件也下载过来。get在FTP脚本中出错也不知为何。
