qt中连接到ftp服务器上后怎么获取服务下所有的文件名

操作方法如下：

@echo off

set h=192.168.1.100

set u=ftpuser

set p=12345678

echo open %h%>ftp.txt

echo %u%>>ftp.txt

echo %p%>>ftp.txt

echo dir>>ftp.txt

echo bye>>ftp.txt

ftp -s:ftp.txt>ftpdir.txt

echo open %h%>ftp.txt

echo %u%>>ftp.txt

echo %p%>>ftp.txt

for /f "tokens=4" %%i in ('findstr "<DIR>" ftpdir.txt') do (

echo cd %%~i>>ftp.txt

echo dir>>ftp.txt

echo cd ..>>ftp.txt)

echo bye>>ftp.txt

ftp -s:ftp.txt>ftpfile.txt

notepad ftpfile.txt

用QFtp应该可以做到吧， 摘自Qt的帮助文档， QFtp::get()时将次二哥参数设置为0，之后收到 readyRead()后可以通过read()或readAll()读取到内存里。

int QFtp::get ( const QString &file, QIODevice * dev = 0, TransferType type = Binary )

If dev is 0, then the readyRead() signal is emitted when there is data available to read. You can then read the data with the read() or readAll() functions.
