网上的这个例子。
void Http::finishedSlot(QNetworkReply* reply)
{
    // Reading attributes of the reply
    // e.g. the HTTP status code
    QVariant statusCodeV = reply->attribute(QNetworkRequest::HttpStatusCodeAttribute);
    // Or the target URL if it was a redirect:
    QVariant redirectionTargetUrl = reply->attribute(QNetworkRequest::RedirectionTargetAttribute);
    // see CS001432 on how to handle this
    // no error received?
    if (reply->error() == QNetworkReply::NoError)
    {
        // Example 2: Reading bytes form the reply
        QByteArray bytes = reply->readAll();  // bytes
//        QString string(bytes); // string
        recieve = 
QString::fromUtf8(bytes);
        //        recieve = QString::fromUtf8(bytes);
//        qDebug() << recieve;
    }
    // Some http error received
    else
    {
        // handle errors here
    }
    // We receive ownership of the reply object
    // and therefore need to handle deletion.
    reply->deleteLater();
}
在程序中服务返回的结果(recieve)被直接处理了(
显示出来了)。我想将这个结果保存起来,我定义了一个实例变量recieve。 
可是我怎样才能将结果返回到调用它的位置呢?
QUrl url(
http://XXXXX);nam->get(QNetworkRequest(url));
此时recieve还
没有返回值啊。
