QFtp::put()问题 [复制链接]

苹果下用put函数上传大文件， 如果文件大于3G的话上传到一定的时间就会自动退出，请问这是什么原因？

记得QFtp已经被废除了

楼上正解
The QFtp class provides an implementation of the client side of FTP protocol.
This class provides a direct interface to FTP that allows you to have more control over the requests. However, for new applications, it is recommended to use QNetworkAccessManager and QNetworkReply, as those classes possess a simpler, yet more powerful API.

我用QFtp已经做了蛮久了，并且任务时间也没有多少了，所以想继续用QFtp;
但是问题就是我问的那样，上传大文件的时候会出错，苹果下它占用了很多的内存，1~2G，下面是苹果下程序崩溃的返回部分信息

楼主 QFTP对大文件上传存在BUG，期待5.0的功能

qftp bug好像还不少呢，
他们提出的用 QNetworkAccessManager and QNetworkReply，这两个没法做直接实现ftp的啊，好麻烦

期待5.0正式版本发布，解决了诸多Bug，省去开发者诸多麻烦
