[Solved]Problem Downloading a file
-
This is my code:
@
iNetReply = iNetManager->get(QNetworkRequest(QUrl("http://myStore-dev.myCompany.com/lmn/00000/fetch?device=00000&file=myFile+.zip")));
@After this request function: connectionError, it's a slot connected in this way:
@
connect(iNetReply, SIGNAL(error(QNetworkReply::NetworkError)), this, SLOT(connectionError(QNetworkReply::NetworkError)));
@Write on console: Error code= 203
@
void PlotterDownloadThread::connectionError(QNetworkReply::NetworkError code)
{
qDebug()<<"Error code= "<<code;
}

as stated earlier, your URL should be percent-encoded. I don't see the .toPercentEncoding() method used, even though you said you used it.
@
iNetReply = iNetManager->get(QNetworkRequest(QUrl("http://myStore-dev.myCompany.com/lmn/00000/fetch?device=00000&file=myFile+.zip")));
@should be
@
iNetReply = iNetManager->get(QNetworkRequest(QUrl("http://myStore-dev.myCompany.com/lmn/00000/fetch?device=00000&file=myFile+.zip").toPercentEncoding()));

[quote]My url already have %_2_B instead of +, but server when i perform get answer: ContentNotFoundError, but if i put the same url into firefox I’m able to download right file.[/quote]
Can you use wireshark or a similar tool to analyze the HTTP traffic and understand what's going on?

[/quote]This is completely nonsense. Not only that doesn't compile, but there's no QNetworkRequest(QByteArray) ctor, and you don't want to percent encode that url (thus escaping :, /, ?, &, etc.).

This is completely nonsense. Not only that doesn't compile, but there's no QNetworkRequest(QByteArray) ctor
[/quote]The compiler will call the non-explicit QString(QByteArray) constructor for this, unless QT_NO_CAST_FROM_ASCII is defined.

[/quote]Nope -- QNetwokRequest wants a QUrl. There are two conversions to be made (QByteArray -> QString -> QUrl), and C++ forbids that (not to mention the fact that you can disable either of them with macros).

Then what should i do?

It's what I'm trying to do...

[/quote]Eek, you're right. I mixed up the parentheses. I need to do more LISP to get used to that ;-)

Solved!!!
Below the solution about my problem:@
QString strUrl="http://myStore-dev.com/zip/mioFile%2_B.zip";QByteArray baUrl(strUrl.toAscii().data());
QUrl tmpUrl1;
tmpUrl1.setEncodedUrl(baUrl);
iNetReply = iNetManager->get(QNetworkRequest(tmpUrl1));
@Thanks to all.
Bye bye.
