商业源码 用bat批处理命令获取ftp服务器目录下的文件名及子目录下的文件名...各位大神帮帮忙
@echo off
set h=1921681100
set u=ftpuser
set p=12345678
echo open %h%>ftptxt
echo %u%>>ftptxt
echo %p%>>ftptxt
echo dir>>ftptxt
echo bye>>ftptxt
ftp -s:ftptxt>ftpdirtxt
echo open %h%>ftptxt
echo %u%>>ftptxt
echo %p%>>ftptxt
for /f "tokens=4" %%i in ('findstr "<DIR>" ftpdirtxt') do (
echo cd %%~i>>ftptxt
echo dir>>ftptxt
echo cd >>ftptxt)
echo bye>>ftptxt
ftp -s:ftptxt>ftpfiletxt
notepad ftpfiletxt
拿去用吧。

服务器上是不存在文件图标的，图标的显示取决于你本地计算机的文件关联情况，要简单的话，你可以准备一些常用文件格式图标（比如rar、zip、doc等等）放在你程序中的资源文件中（比如是jpg或者png格式），然后读取到文件列表后，根据文件的扩展名来调用相应用的图标来显示
。
二、上传：1、获取服务器上和本地要上传文件的同名文件大小；2、向服务器发送“APPE＋文件名”，通知服务器，接下来从数据通道发送给你的数据要附加到这个文件末尾。3、定位本地文件指针（和FTP上文件大小相同的位置）4、从文件指针处读数据并发送。好了，FTP断点续传的原理就这么简单。代码里将断点上传和断点下载放到同一个函数（MoveFile）里，通过get参数说明是上传还是下载。当然，整个FTP类的实现有800多行，包括登录、退出、获取FTP文件大小、删除FTP服务器上文件、响应服务器，解析响应信息等函数。相应的注释代码里都有，这里就不一一熬述了。这里重点说说PASV模式，即被动模式，这是FTP命令里比较不容易理解的一个，这条命令请求服务器在某个端口（非FTP默认端口或控制命令端口）创建一个监听socket，服务器创建的端口号会在客户端的控制命令通道上得到响应。得到这个端口号后，客户端就可以创建新的socket（数据通道）connect过去，并进行文件传输等工作。否则，如果为非被动模式，那么监听的socket由客户端创建，服务器connect过来。对于这条命令的存在我是这么理解的，存在这么一种情况：客户端的IP是个内网的IP，服务器的IP是个外网的，当进行数据传输时内网的IP对于服务器是不可见的，只有由服务器启动监听socket才能建立数据通道，所以必须以被动模式进行。：）
