Download file thru rapidshare API

[raj_iv]

Hi,

How to download a file thru rapidshare API as a free user. I am using 'sub=download' as specified in http://images.rapidshare.com/apidoc.txt API with fileid and filename but the first response that i am getting is completely empty.

A sample code will be of better help.

Can you still download files as unregistered user from RapidShare?
I thought they've disabled it after Megaupload takedown.

[raj_iv]

I think we can download file thru Rapidshare as normal registered user.
We don't need RapidPro user for tat.

You are probably getting a redirection you should follow. What is the status code of the reply you get from the server?

[raj_iv]

yes i am getting redirection with status code 302
but after handling redirection i m not getting any further reply.
Please go thru following code what i m doing (manager is defined as QNetworkAccessManager manager; in class WebServiceManager):

WebServiceManager::WebServiceManager()
: QObject(0)
{
connect(&manager, SIGNAL(finished(QNetworkReply*)),
SLOT(downloadFinished(QNetworkReply*)));
}

void WebServiceManager::downloadFinished(QNetworkReply* reply)
{
if(reply->error() > 0)
{
qDebug() << reply->errorString();
}
else
{
int v = reply->attribute(QNetworkRequest::HttpStatusCodeAttribut e).toInt();

if (v >= 200 && v < 300) // Success
{
... file download code
}
else if (v >= 300 && v < 400) // Redirection - i m getting into this block
{
// Get the redirection url
QUrl newUrl = reply->attribute(QNetworkRequest::RedirectionTargetAttri bute).toUrl();
// Because the redirection url can be relative,
// we have to use the previous one to resolve it
newUrl = reply->url().resolved(newUrl);

QString nurl = newUrl.toString();

QNetworkAccessManager *manager2 = reply->manager();
QNetworkRequest redirection(newUrl);
QNetworkReply *newReply = manager2->get(redirection);

return; // to keep the manager for the next request
}
}
reply->manager()->deleteLater();
reply = 0;
}

Am i doing something wrong for my code to work after redirection.

You certainly shouldn't be calling deleteLater on the manager, it will crash your application upon exit.

So basically you are not getting any response for your second request?

[raj_iv]

yes, i m not getting any response for second request.

[wysota]

Can you show us the url and set of headers set on the second request? You can retrieve them with QNetworkRequest::url() and QNetworkRequest::rawHeaderList() respectively. Also show us the set of headers you get from the reply redirecting you to the new url.

[raj_iv]

This is the Url i am getting on the second request:
https//rs504p10.rapidshare.com/cgi-bin/rsapi.cgi?sub=download&fileid=1117xxxxxx&filename= CPlxxxx.txt

i am not getting any set of headers on second request, its empty...i m printing it with following code:

QList<QByteArray> reqHeaders = redirection.rawHeaderList();

foreach( QByteArray reqName, reqHeaders )
{
QByteArray reqValue = redirection.rawHeader( reqName );
qDebug() << reqName << ": " << reqValue;
}

Also, the header list from reply of second request is also empty.

[wysota]

I can hardly believe that. No content-length, no cookies, no nothing? Note that the api docs says free download always uses http whereas your url uses https.

[raj_iv]

My original url uses http but after redirection i am getting https url.

[wysota]

What is the original url?

[raj_iv]

This is original url:
http//api.rapidshare.com/cgi-bin/rsapi.cgi?sub=download&fileid=1117xxxxxx&filename= CPlxxxx.txt

[raj_iv]

Can anyone pls tell me y i m always redirected to url that begins with https whereas my original url starts with http. How to handle URLs that starts with https using QNetworkAccessmanager.

[wysota]

QNetworkAccessManager doesn't care if your URL is http or https based.

[raj_iv]

But with https URL the slot connected to finished() signal not getting fired. It may be my Qt is not configured with SSL support thus nothing happening beyond tat point in my code...its just hanged.

[wysota]

It may be the other end of your connection does something different than you expect. Or it may be a dozen of other things. Take a network sniffer and find out.
