issue with QWebView handling redirects

[GuusDavidson]

Hi

I am developing in QT 4.6/4.7 targeting Nokia N8 devices.

I have written a news reader application that displays a list of news, music, apps and games, and allows the user to launch into a QWebview to purchase content that can then be downloaded to the device

Now the server side handles matching up the user to their billing account, but what that means is there are a lot of redirects involved from the initial http request.

Now if I launch to the native browser from the application, then the server side billing object is created and I can view and purchase content.

However this same url doesn’t work if I launch it from a QWebview, in fact all I get back is an empty HTML document.
Now the form of the request is something like this (I can't publish actual url’s sorry)

http://www.musicsite.com/getItem.do?id=9999

I can also do it like this

http://www.create-me-a-sessionid.com...em.do?iid=9999

Which should create a billing session and then pass that to www.musicsite.com.

If I manually type the second url into the default web browser then it will create the session id and download the shop web page.

I have created a specialised implementation of the QWebpage, where by I override the user agent, and I am also adding additional header information to the url prior to sending it.

But I am really struggling to get the QWebpage to display this data

As anyone attempted anything similar?
Can anyone offer any advice or assistance?

Thanks in advance

PS sorry for the vague post

Hi,
Hard to say what is the problem, but you could:
1. Sniff http stream (if it's not https) using wireshark, so you can understand which data goes and comes. You can compare the streams sent by your app and by a standard browser.
2. Are cookies enabled?
3. Does your app work using a plain QWebView?
4. Have you tried to check if it works with Arora browser? (it's written completely in Qt!)

I hope my advice can help you a little bit.

Hi gnutton,

Thanks for your suggestions, they are much appreciated,
I hadn't thought of enabling cookies , nor had I heard of the arora browser.

I will try it out

Seems to me that you've got one too many "?" character in that second URL.

If cookies support is turned off of course it won't work.
Let us know how it goes. A network sniffer can even show cookies you get.

I had a quick look through the help on the QNetworkAccessManager class , and as far as the documentation goes I shouldn't have to enable the cookies or write my own cookie jar

http://doc.qt.nokia.com/latest/qnetw...l#setCookieJar

"QNetworkAccessManager by default does not implement any cookie policy of its own: it accepts all cookies sent by the server, as long as they are well formed and meet the minimum security requirements (cookie domain matches the request's and cookie path matches the request's)"
