how to make QHttp work with this URL

[ber_44]

The HTTP example fails at this URL:
http://downloads.sourceforge.net/isisimages/source.zip
How to make it work?

[marcel]

The link is being redirected to here :
http://sourceforge.net/project/downl...se_mirror=kent

On sourceforge I think you're always being redirected to a random mirror.

Maybe you could find out somehow to which mirror you're being redirected.

Read the header location.... from first url and grab the next url ....

on your case

QString QHttpHeader::value ("Location")
return the new url or path...

sample read ....

depend on ip client ... grab the next url mirror....

void RegisterCookie(const QHttpResponseHeader &responseHeader )
{
    ActualCook.clear();
    QStringList cookielist = responseHeader.allValues("set-cookie");
           for (int i = 0; i < cookielist.size(); ++i) {
               QString cokeline = cookielist.at(i);
               QStringList onlines = cokeline.split("=");
               QString cookiename = onlines.at(0);
               QString cookievalue = onlines.at(1);
               ActualCook.insert(i,QStringList() << cookiename << Url_Decode(cookievalue) << actualurl);
               /////////////////qDebug() << "### entry set-cookie pos=" << i << " name= " << cookiename << " value=" << Url_Decode(cookievalue);
           }
    //////////emit WatReturn(QString("One code=%1 - Other say = %2 \n%3").arg( responseHeader.statusCode() ).arg( responseHeader.reasonPhrase() ).arg(CookieVars()) );
}

void RegisterCookie(const QHttpResponseHeader &responseHeader )
{
    ActualCook.clear();
    QStringList cookielist = responseHeader.allValues("set-cookie");
           for (int i = 0; i < cookielist.size(); ++i) {
               QString cokeline = cookielist.at(i);
               QStringList onlines = cokeline.split("=");
               QString cookiename = onlines.at(0);
               QString cookievalue = onlines.at(1);
               ActualCook.insert(i,QStringList() << cookiename << Url_Decode(cookievalue) << actualurl);
               /////////////////qDebug() << "### entry set-cookie pos=" << i << " name= " << cookiename << " value=" << Url_Decode(cookievalue);
           }
    //////////emit WatReturn(QString("One code=%1 - Other say = %2 \n%3").arg( responseHeader.statusCode() ).arg( responseHeader.reasonPhrase() ).arg(CookieVars()) );

Why are you complicating things so much? This should work:

void SomeClass::on_http_responseHeaderReceived( const QHttpResponseHeader &h){
  int code = h.statusCode();
  if(code>=300 && code<400 && h.hasKey("location")){
    http->get(h.value("location"));
    return;
  }
}

void SomeClass::on_http_responseHeaderReceived( const QHttpResponseHeader &h){
  int code = h.statusCode();
  if(code>=300 && code<400 && h.hasKey("location")){
    http->get(h.value("location"));
    return;
  }
}

is ok ... if Location lowercase or uppercase ?? Location say liveheader... and if server not having session cookie....

[wysota]

It should be case insensitive. If you're really interested, take a look at QHttpHeader sources and see if value() is case sensitive.

[ber_44]

wysota, thank you, it makes the HTTP example run without error message, but the file will still not be downloaded. What else should I add to it for a correct download?

[wysota]

I can't say without knowing what's wrong. How do you handle the actual download?

[ber_44]

Well, I just took the official HTTP example by Qt, and added your code to it:

void HttpWindow::readResponseHeader(const QHttpResponseHeader &responseHeader)
{
    // handle redirections
    if (responseHeader.statusCode() >= 300 &&
        responseHeader.statusCode() < 400 &&
        responseHeader.hasKey("location")) {
        http->get(responseHeader.value("location"));
        return;
    }
 
    if (responseHeader.statusCode() != 200) 
        //...
}

void HttpWindow::readResponseHeader(const QHttpResponseHeader &responseHeader)
{
    // handle redirections
    if (responseHeader.statusCode() >= 300 &&
        responseHeader.statusCode() < 400 &&
        responseHeader.hasKey("location")) {
        http->get(responseHeader.value("location"));
        return;
    }
 
    if (responseHeader.statusCode() != 200) 
        //...
}

[wysota]

But is that branch triggered for the redirected url or not?

[ber_44]

Looks like that it gets to a redirection circle, i.e. site1 redirects to site2 which redirects to site1... I'm not sure how to work around this. Somehow it works only from browsers.

Sorry, I realized that there is a direct link:
http://easynews.dl.sourceforge.net/s...ges/source.zip
It works well with this link.
