Qnetworkaccessmanager Implement FTP upload function, solve the file name is Chinese, Qurl contains Chinese path can not upload the problem

The use of Qnetworkaccessmanager FTP upload function, the Internet has a lot of demo, here to say is, upload the time does not contain Chinese characters in the file name OK all OK. If you upload a file with the Chinese name, there will be a problem.

Check a lot of data, Qurl contains Chinese path solution, online answer surprisingly consistent, tried a lot of not, in fact, the reason is not difficult, is the encoding reason.

Don't say it directly on the code.

void Widget::on_pushbutton_2_clicked ()

{

      Qtextcodec *codec= qtextcodec::codecforname ("GBK"); This must be set  according to the system encoding

    Qstringlist pushlist = Qfiledialog::getopenfilenames (This, tr ("Open File"), "C:\\users\\administrator\\desktop", tr (" Video (*.mp4);; PNG (*png);; JPG (*jpg);; GIF (*gif)));

    if (pushlist.length () = = 0)

    {

        Return

      //Open file selector Select Upload file.

    The Qdebug () << "Filenamepath ..." <<pushlist.at (0);

    QString Filenamepath = pushlist.at (0);

    Qstringlist list = Filenamepath.split ("/");

    QString fileName = list.at (List.length ()-1);

    Qfile txt1 (Filenamepath);

    Txt1.open (qiodevice::readonly);

    Qdebug () << "File Open is" <<txt1.isopen ();

    Qbytearray By_txt=txt1.readall ();

    Txt1.close ();

    Qnetworkaccessmanager *manager = new Qnetworkaccessmanager (this);

    QString str1 = "ftp://192.168.2.19/t/";

    QString name =  qstring::fromlatin1 (Codec->fromunicode (FileName));//These one by one sentences are the key to implementing transcoding, remember, only the filename                                                                       //call for the transcoding.

   QString name = Qstring::fromlatin1 (Filename.tolocal8bit ()); Transfer code

    Qurl URL = Qurl (str1 +name);

    Url.setusername ("MS");

    Url.setpassword ("0p-0p-0p-");

    U.setport (21)

    Qnetworkrequest putrequest;

    Putrequest.seturl (URL);

    Qnetworkreply *putreply = Manager->put (Putrequest, by_txt);

    Connect (putreply, SIGNAL (finished ()), this, SLOT (slotfinished ()));

    Connect (putreply, SIGNAL (uploadprogress (Qint64,qint64)), This,slot (Uploadprogress (Qint64,qint64));

    Connect (putreply, SIGNAL (Error (Qnetworkreply::networkerror)), This,slot (Sloterror (Qnetworkreply::networkerror)) ;

}

Update progress bar

void Widget::uploadprogress (Qint64 bytessent, Qint64 bytestotal)

{

    Qdebug () << "Bytestotal >>>> bytessent .... "<<bytesTotal<<bytesSent;

    Ui->progressbar->setmaximum (bytestotal);

    Ui->progressbar->setvalue (bytessent);

}

Error function

void Widget::sloterror (Qnetworkreply::networkerror erro)

{

    Qnetworkreply *reply = (qnetworkreply *) sender ();

    if (reply->error () = = Erro)

    {

        Qdebug () << "Error!!!!!!!!!!!!!!!!!!" <<qstring::fromutf8 (Reply->readall ());

    }

}

Transfer completion function

void Widget::slotfinished ()

{

    Qnetworkreply *reply = (qnetworkreply *) sender ();

    if (reply->error () = = Qnetworkreply::noerror)

    {

        Qdebug () << "succed!";

    }

    Else

    {

        Qdebug () << "Check & Retry!!!!!!!";

    }

}

Select a "MP4" file to the FTP server.
