QNetworkCookieJar

[anda_skoa]

//Setup QNetwork
    loginnam = new QNetworkAccessManager();
 
    //Cookies
    NetworkJar njarobj;
    loginnam->setCookieJar(&njarobj);
    njarobj.setParent(0);

//Setup QNetwork
    loginnam = new QNetworkAccessManager();

    //Cookies
    NetworkJar njarobj;
    loginnam->setCookieJar(&njarobj);
    njarobj.setParent(0);

That is unlikely to work properly, njarobj is on the stack and will go out of scope at then end of the block (probably a function body).

What if I don't want to implement my own security policy or whatever, do I need to implement my own setCookiesFromUrl ?

You don't need a derived class if you don't want to change anything that QNetworkCookieJar does

Don't I need to specify the location to store cookies?

QNetworkCookieJar does not persist cookies. Any derived class that implements persistence needs to address this depending on the persistence mechanism chosen for its implementation.

But I don't see that function, so I assume I'll need to reimplement SetCookiesFromUrl to store to disk and CookiesFromUrl to get from disk?

Or using explicit save/load methods that get called at the end/start of the program.

Using QFile?

Indeed a valid option.

Networkjar.cpp

#include "networkjar.h"
#include <QFile>
#include <QDateTime>
#include <QTextStream>
 
NetworkJar::NetworkJar()
{    
}
bool NetworkJar::setCookiesFromUrl(const QList<QNetworkCookie> &cookieList, const QUrl &url)
{
    QList<QNetworkCookie> cookies = QNetworkCookieJar::allCookies();
 
    QFile cookiesfile("Cookies");
    QTextStream out(&cookiesfile);
    if (!cookiesfile.open(QFile::WriteOnly | QFile::Text))
    {
        return false;
    }
    foreach (QNetworkCookie cookie, cookieList)
    {
        cookies += cookie;
        out << "Name:" << cookie.name() << "Value:" << cookie.value() << "Path:" << cookie.path() << "Expire Date:" << cookie.expirationDate().toString();
    }
    return true;
}

#include "networkjar.h"
#include <QFile>
#include <QDateTime>
#include <QTextStream>

NetworkJar::NetworkJar()
{    
}
bool NetworkJar::setCookiesFromUrl(const QList<QNetworkCookie> &cookieList, const QUrl &url)
{
    QList<QNetworkCookie> cookies = QNetworkCookieJar::allCookies();

    QFile cookiesfile("Cookies");
    QTextStream out(&cookiesfile);
    if (!cookiesfile.open(QFile::WriteOnly | QFile::Text))
    {
        return false;
    }
    foreach (QNetworkCookie cookie, cookieList)
    {
        cookies += cookie;
        out << "Name:" << cookie.name() << "Value:" << cookie.value() << "Path:" << cookie.path() << "Expire Date:" << cookie.expirationDate().toString();
    }
    return true;
}

To copy to clipboard, switch view to plain text mode 

That seems to ignore the "url" argument, which will likely make it difficult to then later retrieve the cookies for that URL.
