爲什麼我的自定義cookiejar不起作用？

Question

我需要通過qnetworkcookiejar從本地磁盤加載cookie，但是當我嘗試時它不起作用。這裏是我的代碼：

QNetworkCookieJar *cookieJar = new QNetworkCookieJar; 
    QFile file("d:/cookie.txt"); 
    file.open(QIODevice::ReadOnly | QIODevice::Text); 
    QTextStream in(&file); 
    while (!in.atEnd()) { 
     QString line = in.readLine(); 
     QList<QNetworkCookie> cookie = QNetworkCookie::parseCookies(line.toLocal8Bit()); 
     foreach (QNetworkCookie c, cookie) { 
      qDebug() << cookieJar->insertCookie(c); 
     } 
    } 
    QUrl url = QUrl(QString("http://www.renren.com/")); 

    QWebView view; 
    QWebInspector inspector; 
    inspector.setPage(view.page()); 
    view.settings()->setAttribute(QWebSettings::DeveloperExtrasEnabled, true); 
    view.settings()->setAttribute(QWebSettings::PrivateBrowsingEnabled, false); 

    QNetworkAccessManager *manager = new QNetworkAccessManager; 
    manager->setCookieJar(cookieJar); 
    view.page()->setNetworkAccessManager(manager); 

    inspector.setVisible(true); 
    view.show(); 
    QEventLoop loop; 
    QObject::connect(&view, SIGNAL(loadFinished(bool)), 
        &loop, SLOT(quit())); 
    view.load(QString("http://www.renren.com"));

似乎沒餅乾在webinspector當我加載www.renren.com。有人能幫我嗎？

繼Qt文檔後，如果您想要在磁盤上存儲cookie，您應該繼承QNetworkCookieJar。此外，使用QSettings時，加載和保存操作非常簡單。下面是我peristent版本QNetworkCookieJar實現的：

.H

class CMyNetworkCookieJar : public QNetworkCookieJar 
{ 
    Q_OBJECT 

public: 
    CMyNetworkCookieJar(QObject *p_pParent = NULL); 
    ~CMyNetworkCookieJar(void); 

    bool setCookiesFromUrl(const QList<QNetworkCookie> & p_grCookieList, const QUrl & p_grUrl); 
    QList<QNetworkCookie> cookiesForUrl(const QUrl & p_grUrl) const; 

    void loadCookies(void); 
    void saveCookies(void); 

protected: 
    QSettings * m_pCookieStorage; 
}; 

的.cpp

CMyNetworkCookieJar::CMyNetworkCookieJar(QObject * p_pParent) 
    : QNetworkCookieJar(p_pParent) 
{ 
    m_pCookieStorage = new QSettings(QSettings::IniFormat, 
            QSettings::UserScope, 
            QApplication::organizationName(), 
            QApplication::applicationName()); 

    loadCookies(); 
} 

CMyNetworkCookieJar::~CMyNetworkCookieJar() 
{ 
    saveCookies(); 
    m_pCookieStorage->sync(); 

    delete m_pCookieStorage; 
} 

bool CMyNetworkCookieJar::setCookiesFromUrl(const QList<QNetworkCookie> & p_grCookieList, const QUrl &p_grUrl) 
{ 
    return QNetworkCookieJar::setCookiesFromUrl(p_grCookieList, p_grUrl); 
} 

QList<QNetworkCookie> CMyNetworkCookieJar::cookiesForUrl(const QUrl &p_grUrl) const 
{ 
    return QNetworkCookieJar::cookiesForUrl(p_grUrl); 
} 

void CMyNetworkCookieJar::loadCookies() 
{ 
    QByteArray grCookies = m_pCookieStorage->value("cookies").toByteArray(); 
    QList<QNetworkCookie> grCookieList = QNetworkCookie::parseCookies(grCookies); 
    setAllCookies(grCookieList); 
} 


void CMyNetworkCookieJar::saveCookies() 
{ 
    QList<QNetworkCookie> grCookieList = allCookies(); 
    QByteArray grCookies; 

    foreach(QNetworkCookie grCookie, grCookieList) 
    { 
     if (grCookie.isSessionCookie() == false) 
     { 
      grCookies.append(grCookie.toRawForm()); 
      grCookies.append("\n"); 
     } 
    } 

    m_pCookieStorage->setValue("cookies", grCookies); 
}
