qt能否直接从ftp服务器上读取文本文件内容？

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
