FTP access with Qt 5.3
-
Okay, I've tried to avoid asking this question but I simply cannot wrap my head around how to work with a ftp site and use QNetworkAccessManager. Qt's documentation explains how to use the classes is pieces. But doesn't have a good example that shows how to use them together.
Part of the confusion lies in the fact that apparently in Qt 5 they no longer support QFtp--or at least discourage us from using it. But every example I can find uses QFtp!
So my basic starting point is, I wanted to log into my ftp site and just get a list of files from a given directory, how is this done with QNetworkAccessManager? Here's what I've done so far. But clearly, this isn't executing a pwd command. Not sure where that even occurs...
// Header
@#ifndef NETWORKMANAGER_H
#define NETWORKMANAGER_H#include <QObject>
#include <QNetworkAccessManager>class QNetworkReply;
class QNetworkAccessManager;
class NetworkManager : public QObject
{
Q_OBJECT
private:
QNetworkAccessManager m_netman;public:
explicit NetworkManager(QObject *parent = 0);
~NetworkManager();bool ftpTester();
signals:
public slots:
void replyFinished(QNetworkReply *_reply);};
#endif // NETWORKMANAGER_H
@// Cpp
@#include "NetworkManager.h"
#include <QNetworkRequest>
#include <QNetworkReply>
#include <QUrl>
#include <Underworld/Base/NStatus.h>NetworkManager::NetworkManager(QObject parent) :
QObject(parent)
{
connect(&m_netman, SIGNAL(finished(QNetworkReply)),
this, SLOT(replyFinished(QNetworkReply*)));
}NetworkManager::~NetworkManager()
{
}bool NetworkManager::ftpTester()
{
QNetworkRequest request(QUrl("ftp://<username>:<password>@ftp.mysite.com/sweetFTP/"));
m_netman.get(request);
return false;
}void NetworkManager::replyFinished(QNetworkReply *_reply)
{
if( _reply->error())
{
NStatus::nowError("Unable to get to ftp site.");
NStatus::nowError(_reply->errorString());
} else {
NStatus::nowNote(_reply->header(QNetworkRequest::ContentTypeHeader).toString());
}
_reply->deleteLater();
}@any direction, tutorials I can read or any code samples would be appreciated!

For the time being you can only use put() and get() when accessing ftp with QNetworkAccessManager ie. upload or download a file assuming you know the path beforehand. To use commands like "PWD" or "LIST" you would have to go a level down, to a QTcpSocket I suppose.

There is also "QtFtp":https://qt.gitorious.org/qt/qtftp/source/80823b53d2025d9c0c15075c325ee0c2e364551b: which is referred "here":http://qt-project.org/forums/viewthread/24466
You can see in the example how to use QNetworkAccessManager as QFtp used to be. Alternatively, you can use the easy route and use the compatibility class directly.
