The Save/Load



I tried to check for cookie name before writing to file but this is outputting nothing?

//Setup
    QList<QNetworkCookie> cookies = QNetworkCookieJar::allCookies();
    QFile cookiesfile("cookiefile");
    QTextStream in(&cookiesfile);
    QList<QString> savedcookies;
 
    //Read
    if (!cookiesfile.open(QFile::ReadOnly | QFile::Text))
    {
        emit networkreplyError("Failed to open file for reading!");
    }
    while (!cookiesfile.atEnd())
    {
        savedcookies << in.readLine();
    }
    in.flush();
    cookiesfile.close();
 
    //Append
    QTextStream out(&cookiesfile);
    if (cookiesfile.open(QFile::Append | QFile::Text))
    {
        emit networkreplyError("Failed to open file for reading");
    }
 
    foreach (QNetworkCookie cookie, cookieList)
    {
        for (int i = savedcookies.size()-1; i >= 0; i--)
        {//will add check URL later
            if (!savedcookies.at(i).contains(cookie.name()))
            {
                //Name, Value, Path, Domain, Expire Date, URL
                out << "Name:" << cookie.name() << "  spliter " << "Value:" << cookie.value() << "  spliter " << "Path:" << cookie.path() << "  spliter " << "Domain:" << cookie.domain() << "  spliter " << "Expire Date:" << cookie.expirationDate().toString() << "  spliter " << "URL:" << url.toString() << endl;
                out.flush();
                cookies += cookie;
            }
        }
    }
 
    //Close and Return
    cookiesfile.close();
    return true;

//Setup
    QList<QNetworkCookie> cookies = QNetworkCookieJar::allCookies();
    QFile cookiesfile("cookiefile");

Hello, everyone

[anda_skoa]

The Save/Load

Oh, I thought that would be self explanatory :-)
A save method would write the cookies into a file and a load method would read them from a file.

I tried to check for cookie name before writing to file but this is outputting nothing?

I am not quite sure what you are trying to do here and where in the class you are doing it.
Trying to avoid duplicates in setCookiesForUrl()?

That would be another thing that is easier in an explicit save method, because there you can just overwrite the file with the current jar content.

I mean what save/load is that, that get "called at the end/start" ?
Maybe I misinterpreted this.
You probably saying create functions that get called at the end/start, not some special qt save/load function that is not created by me


I'm in NetworkJar class, subclass QNetworkCookieJar.
That function is setCookiesforUrl, trying to check if cookies already exists before writing.

Exactly. I was suggeting to use explicit methods for saving and loading instead of making the setter and getter do it on every invocation.

Do I need to use setallcookies if I returned a Qlist<QNetworkCookie> in cookiesforurl ???

[anda_skoa]

I doubt it. setAllCookies() sounds more like the function you would call in a load method, i.e. to initially fill the cookie jar.

The Qt browser demo implements cookie persistence. See cookiejar.h and cpp.
