I get only 1 of 4 cookies...

[cherva]

I'm trying to get a web page that returns to me 4 cookies with this part of code:

QNetworkAccessManager *manager = new QNetworkAccessManager(this);
 QNetworkRequest request;
 request.setUrl(QUrl(line));
 request.setRawHeader("User-Agent", "Firefox/3.0.10");
 
 reply = manager->get(request);
 
 connect(reply, SIGNAL(finished()), this, SLOT(slotReadyRead()));
 
void Window::slotReadyRead(){
 QList<QByteArray> headers=reply->rawHeaderList();
    QVariant cookies=reply->header(QNetworkRequest::SetCookieHeader);
    wget = reply->readAll();
    QList<QVariant> list = cookies.toList();
   qDebug()<<"HEADERS: "<< headers[2] << " COOKIES: " << list.size();
   qDebug()<<"COOKIES FROM rawHEADER: " << reply->rawHeader("Set-Cookie") ;
...
...
...

QNetworkAccessManager *manager = new QNetworkAccessManager(this);
 QNetworkRequest request;
 request.setUrl(QUrl(line));
 request.setRawHeader("User-Agent", "Firefox/3.0.10");

 reply = manager->get(request);

 connect(reply, SIGNAL(finished()), this, SLOT(slotReadyRead()));

void Window::slotReadyRead(){
 QList<QByteArray> headers=reply->rawHeaderList();
    QVariant cookies=reply->header(QNetworkRequest::SetCookieHeader);
    wget = reply->readAll();
    QList<QVariant> list = cookies.toList();
   qDebug()<<"HEADERS: "<< headers[2] << " COOKIES: " << list.size();
   qDebug()<<"COOKIES FROM rawHEADER: " << reply->rawHeader("Set-Cookie") ;
...
...
...

To copy to clipboard, switch view to plain text mode 

The output of the program is:

HEADERS:  "Set-Cookie"  COOKIES:  0 
COOKIES FROM rawHEADER:  "JSESSIONID=F9C30312025976F6A8A4813CC96B8E65; Path=/app"

HEADERS:  "Set-Cookie"  COOKIES:  0 
COOKIES FROM rawHEADER:  "JSESSIONID=F9C30312025976F6A8A4813CC96B8E65; Path=/app"

The cookies from rawHEADER is only 1 ... the server sends 4... what is wrong ?

[e8johan]

How does the raw header list look if you iterate over it and print it, e.g.

foreach( QByteArray b, reply->rawHeaderList() )
  qDebug() << b;

foreach( QByteArray b, reply->rawHeaderList() )
  qDebug() << b;

Perhaps there are several set cookie entries....

Have you used wireshark or something similar to verify that you actually do get four cookies?

[cherva]

Yes, Wireshark sends me 4 cookies:

The strange thing is that the output of the program was:

COOKIES FROM rawHEADER:  "JSESSIONID=D106ADD7E19F1913E020E542B8C73EFB; Path=/app"

COOKIES FROM rawHEADER:  "JSESSIONID=D106ADD7E19F1913E020E542B8C73EFB; Path=/app"

the cookie is not the same

[e8johan]

Comparing your wireshark output to the output from the foreach-loop described earlier, you seem to miss other entries as well.

What do you get from reply.readAll() ?

[cherva]

I get the page that I should get when I login with wrong user or password or in my case with wrong cookies....

[e8johan]

Does that mean that you have to add something to your request? Or do you mean that you get too few cookies but expect it to work?

[cherva]

I need all four cookies it won't work with just one.

[e8johan]

How does the QNetworkAccessManager's QNetworkCookieJar look?

[cherva]

Can you tell me how to check because allCookies() is protected and I don't want to subclass the whole class....

[e8johan]

I'd go or the cookiesForUrl function.

[cherva]

I inserted

QList<QNetworkCookie> jar=manager->cookieJar()->cookiesForUrl(QUrl(line));

QList<QNetworkCookie> jar=manager->cookieJar()->cookiesForUrl(QUrl(line));

To copy to clipboard, switch view to plain text mode 

on line 7
and in debug mode jar stayed empty until the program ended.

[e8johan]

How does the original URL look? Do you try to login here, or do you try to access some location where you already are logged in? If so, how did you originally log in there?

You say that you reach the login/wrong password page, and that seems reasonable to me if you don't have any cookies...

[cherva]

Here is the deal:
1) I send the user and password to the server that the original http://abv.bg 's form will send the data.
2) The server returnes me "HTTP 302 Moved temporarily" and a link like:
http://mailXX.abv.bg/servlet/plogin?s=hewirhwekrjhwekjrhw.passportX" wher re X's are random nubers.
3) When I go to that page I get the same HTTP 302 Moved temprarily message but with differtent mailXX.
4) I go there and this page gives me 4 cookies: example:

Set-Cookie: JSESSIONID=4D6B05D58928843F51D03F6D85ED5F40; Path=/app\r\n
    SET-COOKIE: _key=7710db16cea77c8152a557a0ab0469cc; Path=/app; HTTPOnly\r\n
    Set-Cookie: uhost=mail33.abv.bg; Domain=.abv.bg; Path=/\r\n
    Set-Cookie: usid=4D6B05D58928843F51D03F6D85ED5F40; Domain=.abv.bg; Path=/\r\n

Set-Cookie: JSESSIONID=4D6B05D58928843F51D03F6D85ED5F40; Path=/app\r\n
    SET-COOKIE: _key=7710db16cea77c8152a557a0ab0469cc; Path=/app; HTTPOnly\r\n
    Set-Cookie: uhost=mail33.abv.bg; Domain=.abv.bg; Path=/\r\n
    Set-Cookie: usid=4D6B05D58928843F51D03F6D85ED5F40; Domain=.abv.bg; Path=/\r\n

and redirects me to "http://mailXX.abv.bg/app/j/home.jsp" whre the XX are from the last page . ( the page that gave me the cookies)
This is what I need. I used WGET to deal with the cookies and everything is ok, but my program reached version 1.00 and I want to remove it because it's stupid for the windows version to come with a hidden wget.exe in the same folder.

[wysota]

In general I'd say that what the server returns you could be a bit invalid. From what I understand (I could be wrong though) there should only be one header of each type therefore you only get one set-cookie header that contains all cookies that are to be set separated by semicolons.

QNetworkReply::header() should return you a QVariant when passed QNetworkRequest::SetCookieHeader. This variant is really QList<QNetworkCookie>. When you get hold of it, you can list its contents to check out what cookies you are set. Then you can store them in your cookie-jar.

Be sure to cast the variant to a proper type or else you will get an empty list like you do now.

[cherva]

I tried that on line 12 and 14 on the first post and "list" is empty.

[wysota]

Read again my last sentence and see what QVariant::toList() returns.

[cherva]

QVariant cookies=reply->header(QNetworkRequest::SetCookieHeader);
    QList<QVariant> list = cookies.toList();

QVariant cookies=reply->header(QNetworkRequest::SetCookieHeader);
    QList<QVariant> list = cookies.toList();

To copy to clipboard, switch view to plain text mode 

Makes cookies = QList<QNetworkCookie> and list = 0 items

[wysota]

No, it makes it QList<QVariant> and not QList<QNetworkCookie> thus the size is 0 (because it is not a QList<QVariant>).
