qtsoap doesn't work with ebay web service

[freeppe]

We write qt project to Nokia web-laboratory in Petrozavodsk. We have problem with qtsoap library:
Subproject must work with ebay web-service
content files:
ebay.cpp http://paste.org/pastebin/view/15525
ebay.h http://paste.org/pastebin/view/15526

main.cpp:
#include <QtCore/QCoreApplication>
#include "ebay.h"
int main(int argc, char *argv[])
{
eBayRequest *ebay = new eBayRequest();
ebay->submitRequest();
QCoreApplication a(argc, argv);

return a.exec();
}

When project post http request to ebay, we get this XML file with error: "Transport failed: Host not found";
We think, that header arguments, which need to ebay auth, is not connected to request.
Help us, if you know.

P.s. Sorry to my bad english...

Well, just look at your code:

connect(&http;, SIGNAL(responseReady()), SLOT(getResponse()));

[freeppe]

What this? We connect http->responceReady to this->getResponce.. I think that this is all right..

[divanov]

Your code doesn't compile due to multiple C++ syntactical mistakes. You can fix them and re-post proper code.

Now I`m publicing a complete repository of this subproject. I can compline it. Most likely you can`t compile it because it needs the qtsoap libraries. You can download the project and the library. You may have change in the pro file. Thanks for supporting.

Sorry i have sended first time the false version, the second version is the better one.

[divanov]

You should not use scheme while setting the host, since the resulting QUrl you get is something like "http://http://open.api.ebay.com". Naturally, there is no such host.

[freeppe]

If fill url as "open.api.ebay.com", then we get:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/1999/XMLSchema">

What is difference between these two code snipplets?

QtSoapQName name;
QtSoapType *type;
 
name = QtSoapQName("X-EBAY-API-VERSION", QString::number(eBayRequest::Version));
type = new QtSoapType(name, QtSoapType::AnyURI);
qDebug() << type->isValid();

QtSoapQName name;
QtSoapType *type;

name = QtSoapQName("X-EBAY-API-VERSION");
type = new QtSoapSimpleType(name, QString::number(eBayRequest::Version));
qDebug() << type->isValid();

Thank you, we have corrected this error. But alas SOAP-message response has not changed. So far, remained a mistake. If you see some other gross errors, help us to understand this. Thank you for your support.

Since this question is about eBay shoping API (and this API is deprecated):
http://developer.ebay.com/DevZone/sh...FindItems.html
you can ask how to use shopping API properly on eBay forums:
