qt - QNetworkAccessManager returning empty results -


i struggling qnetworkaccessmanager quite sometime. googled lot, donot find solution this.

i creating client using qaccessmanager talk rest server. qnetworkreply not returning results. server working client not returning results. on top of server gets called 3 times , server crashing. hope 1 can figure out going wrong. attaching client code.

i tried different approches connecting finished signal of networkaccessmanager, qnetworkreply e.t.c. of them ends in giving same error "connection closed" or readall bytearray being empty.

void restclientcore::connecttoserver() {    m_networkmanager  = new qnetworkaccessmanager(this);      qurl url("http://localhost");     url.setport(5432);     qbytearray postdata;      postdata.append("/?userid=user");      postdata.append("&site=site");     qnetworkreply *reply = m_networkmanager->post(request,postdata);     connect(reply, signal(readyread()),this, slot(slotreadyread()));     connect(reply, signal(finished()), this, slot(onrequestcompleted())); }  void restclientcore::onrequestcompleted() {    qnetworkreply *reply = qobject_cast<qnetworkreply *>(sender());     if(reply->error())     {       qdebug() <<reply->bytesavailable() << reply->errorstring();     }     else     {       qdebug() << reply->readall();     }     reply->deletelater(); }  void restclientcore::slotreadyread() {    qnetworkreply *reply = qobject_cast<qnetworkreply *>(sender());    qdebug() << reply->readall(); }
