Qt发送较高频率post请求返回:NetworkError(RemoteHostClosedError) 和NetworkError(NetworkSessionFailedError)错误

采用Qt给远程服务器发送post请求，代码如下:

    connect(accessManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(finishedSlot(QNetworkReply*)));
  ...
    int n = 0;
    while (n<100)
    {
        n++;
        QByteArray post_data = "";
        QNetworkReply* reply = accessManager->post(request, post_data);
        
        QTime dieTime = QTime::currentTime().addMSecs(48);//采用不同频率发送post请求，10Hz左右能稳定获得数据，频率超过10Hz就会报标题所示错误
        while (QTime::currentTime() < dieTime)
            QCoreApplication::processEvents(QEventLoop::AllEvents, 2);
    }
 ...
  void Http_Get::finishedSlot(QNetworkReply *reply)
    {
    
        if (reply->error() == QNetworkReply::NoError)
      {
        ...
      }
      else
      {
        qDebug() << "finishedSlot errors here" << reply->error();
        qDebug("found error .... code: %d\n", (int)reply->error());
        qDebug(qPrintable(reply->errorString()));
      }
      reply->deleteLater();
}

当发送频率超过10Hz就会出现NetworkError(RemoteHostClosedError) 和NetworkError(NetworkSessionFailedError)错误。想问这是服务器的问题还是post请求发送问题？感谢。

也许是服务器端作了限制
