Question

In my project i want to download files from server. I am trying to download files using Qnetwrokaccessmanager. in my code am using a connect function like

connect(manger_, SIGNAL(finished(QNetworkReply *)), this, SLOT(replyFinshed(QNetworkReply*)))

On the time execution of project does not call the function replayFinshed()

manger_= new QNetworkAccessManager(this);
connect(manger_, SIGNAL(&QNetworkAccessManager::finished), this, SLOT(replyFinshed(QNetworkReply*)));
connect(manger_, SIGNAL(QNetworkReply::error()), SLOT(errmsg(QNetworkReply *)));
QUrl url(str);
QNetworkRequest request;
request.setUrl(url);
rsult = manger_->get(request);



void Cricbang::replyFinished(QNetworkReply* reply){
    QMessageBox::information(this, "replay", "finished");
    if (reply->error())
    {
        qDebug() << "ERROR!";
        qDebug() << reply->errorString();
    }
    else
    {
        QFile *file = new QFile("saved/team.json");
        if (file->open(QFile::Append))
        {
            file->write(reply->readAll());
            file->flush();
            file->close();
        }
        delete file;
    }

    reply->deleteLater();

Try changing

connect(manger_, SIGNAL(&QNetworkAccessManager::finished), this, SLOT(replyFinshed(QNetworkReply*)));

to

connect(manger_, SIGNAL(finished(QNetworkReply*)), this, SLOT(replyFinshed(QNetworkReply*)));

or use the new syntax introduced in Qt5 like eyllanesc suggested

connect(manger_, &QNetworkAccessManager::finished, this, &Cricbang::replyFinshed);
