QNetworkReply 没有数据

Question

我有一个 QWebView，我正在通过连接观看网络请求：

  QObject::connect(page()->networkAccessManager(),
                     SIGNAL(finished(QNetworkReply*)),
                     this,
                     SLOT(networkLoaded(QNetworkReply*)));

然后：

void browserControl::networkLoaded(QNetworkReply *reply)
{
    const QUrl reqUrl = reply->request().url();
    qDebug() << "url = " << reqUrl;

    QByteArray array = reply->readAll();
    QString data = QString::fromUtf8(array.data(), array.size());
    int statusCode = reply->attribute(QNetworkRequest::HttpStatusCodeAttribute).value<int>();

 qDebug() << "data = " << data;
    qDebug() << "http code = " << statusCode;
}

但是数据总是空的，不管statusCode是200。 browserControl class 继承自 QWebView class.
