QNetworkAccessManger is not ok for mem

test_song

Que: my Code is this,QT Ver is QT5.9.4

ohh,My program encountered a problem。
in slots function replyFinished . reply-deleter() is called before return. but the mem continues to increase。
I expect for your reply 。thanks.

    QNetworkReply *replay=http->post(req, d);
    connect(replay,SIGNAL(finished(QNetworkReply*)),this,SLOT(replyFinished(QNetworkReply*)));
    replyTimeout *reply_timer=new replyTimeout(replay,5000);

void httpRequest::replyFinished(QNetworkReply *reply)
{
    QString r_url;
    r_url=reply->url().toString();
    QByteArray r_byte;
    r_byte.clear();

    if(reply->error() != QNetworkReply::NoError)
    {

        r_byte=reply->errorString().toUtf8();
        send_notify_err(r_url,1);
        qDebug("QNetworkReply::err  %d",reply->error());
        reply->deleteLater();
        return ;
    }
    r_byte= reply->readAll();
    if (r_byte.isEmpty())
    {
        r_byte=QString("isEmpty").toUtf8();

        send_notify_err(r_url,2);

        reply->deleteLater();

        qDebug()<<"r_content isEmpty()";

        return ;
    }

   // m_callbackFunc(&r_url,&r_byte);
    reply->deleteLater();
    send_notify_msg(r_url,r_byte);

}

@test_song said in QNetworkAccessManger is not ok for mem:

replyTimeout *reply_timer=new replyTimeout(replay,5000);

What do you use this for? In the code you posted you do not delete it.

@test_song said in QNetworkAccessManger is not ok for mem:

reply_timer

this reply_timer is a class to monitor ,reply is it's father, it deleted with reply erased
class replyTimeout : public QObject {

Q_OBJECT

public:
replyTimeout(QNetworkReply *reply, const int timeout) : QObject(reply) {
Q_ASSERT(reply);
if (reply && reply->isRunning()) { // 启动单次定时器
QTimer::singleShot(timeout, this, SLOT(onTimeout()));
}
}
~replyTimeout()
{
qDebug()<<"~replyTimeout";
}
private slots:
void onTimeout() { // 处理超时
QNetworkReply reply = static_cast<QNetworkReply>(parent());
if (reply->isRunning()) {
qDebug() << "abort reply "<< reply->url().toString();
reply->abort();
}
}
};
