C++ QObject:无法使用QtConcurrent:：run为位于不同线程中的父线程创建子线程

我试图在qt中使用线程，但在我使用的代码中出现了一些奇怪的错误

我使用的函数是线程

QThreadPool::globalInstance()->setMaxThreadCount(size);
QFutureSynchronizer<void> synchronizer;

for(quint64 i=0;i<size;i++)
{
    synchronizer.addFuture(QtConcurrent::run(this, &Market::tickerForThread,markets[permission[i]],QString("%1%2/value").arg(url).arg(permission[i])));
}
synchronizer.waitForFinished();

还有我犯的错误

QObject: Cannot create children for a parent that is in a different thread.
(Parent is QNetworkAccessManager(0xa64d80), parent's thread is QThread(0x6f9270), current thread is QThread(0xad4490)
QObject: Cannot create children for a parent that is in a different thread.

错误的原因是什么？如何解决？ 谢谢你的回复

错误的原因是什么？如何解决

父母和孩子必须生活在同一条线上。解决方法是将它们分别移动到同一个线程中

您要么需要将QNAM实例移动到子线程，要么需要移动子线程。如果不进一步澄清上下文，我无法告诉您比这更具体的建议。

laszlo，我使用了tickerForThread中的get函数来减速新的QNetworkAccessManager，但对我来说仍然太慢。我需要10-20个与QNetworkAccessManager同步我如何处理它？使用多个QNetworkAccessManager？是的，我终于解决了这个问题。但我改变了我不再使用的类的结构QtConcurrent:：run，因为QNetworkAccessManager已经有了自己的线程。@VeyselBekirMacit:太好了，那么我的答案缺少什么？@VeyselBekirMacit，啊，好的。：）这么简单完美的解释！非常感谢。
