You could try a QNetworkAccessManager::put() operation with an ftp URL.

QNetworkAccessManager *Ftp = new QNetworkAccessManager(this);
            QNetworkReply *reply = new  QNetworkReply (this);
            QUrl url  ("ftp://192.168.192.91/test.txt");
            url.setUserName(test);
            url.setPassword(test);
            url.setPort(21);
 
 
            QFile *data = new QFile(test.txt);
 
            if(!data->open(QIODevice::ReadOnly))
            {
                qDebug() << "Could not open file to FTP";
                QMessageBox::information(this,"FTP ","Could not open file to FTP");
                return false;
 
            }
            else
            {
                reply = Ftp->put(QNetworkRequest(url),data);
            }

QNetworkAccessManager *Ftp = new QNetworkAccessManager(this);
            QNetworkReply *reply = new  QNetworkReply (this);
            QUrl url  ("ftp://192.168.192.91/test.txt");
            url.setUserName(test);
            url.setPassword(test);
            url.setPort(21);
      

            QFile *data = new QFile(test.txt);

            if(!data->open(QIODevice::ReadOnly))
            {
                qDebug() << "Could not open file to FTP";
                QMessageBox::information(this,"FTP ","Could not open file to FTP");
                return false;

            }
            else
            {
                reply = Ftp->put(QNetworkRequest(url),data);
            }

To copy to clipboard, switch view to plain text mode 

but i getting error like this

QIODevice::read: device not open
Error Code: "Unknown error"


can anybody tell why it is coming and give some solution....

[anda_skoa]

QNetworkReply *reply = new  QNetworkReply (this);

QNetworkReply *reply = new  QNetworkReply (this);

To copy to clipboard, switch view to plain text mode 

Any specifc reason why you create a QNetworkReply object here?

QUrl url  ("ftp://192.168.192.91/test.txt");

QUrl url  ("ftp://192.168.192.91/test.txt");

To copy to clipboard, switch view to plain text mode 

Is that a writable location on the target server?

but i getting error like this

QIODevice::read: device not open
Error Code: "Unknown error"

When do you get this?

Cheers,

[mouni]

no

it is a writable location on server


while uploading file error is coming

[anda_skoa]

it is a writable location on server

Ok.

while uploading file error is coming

So you have connected to the QNetworkReply::error() signal and it is emitted before finished()?

Where do you close/delete the "data" object? In the slot for QNetworkReply::finished()?

Maybe try "post" instead of "put".

[mouni]

it is showing QIODevice::read: device not open

but files uploading to server...

what is problem i am not understanding

[anda_skoa]

Are you maybe calling "read" or "readAll" on the reply object?

Cheers,

[mouni]

i am not calling read or readall


when file is given QIODevice::readonly i given..

QFile *data = new QFile(test.txt);

if(!data->open(QIODevice::ReadOnly))
{
qDebug() << "Could not open file to FTP";
QMessageBox::information(this,"FTP ","Could not open file to FTP");
return ;
}
reply = Ftp->put(QNetworkRequest(url),data);

where data is QFile

reply is qnetworkreply

ftp is qnetworkacessmanager...
