QNetworkAccessManager工作得很好，然后每次都在get（）方法上开始崩溃，这很简单：
QNetworkReply *reply = myManager->get(QNetworkRequest(QUrl(myUrl)));

P.S。现在有时会开始崩溃：
QList<QNetworkInterface> interfaces = QNetworkInterface::allInterfaces();
其他团队成员运行此代码时，其他PC和地方都没有问题。原因是什么？！网络问题，防病毒，防火墙（试图切断两者没有运气）等？！为什么它调用QNetworkProxy :: setPassword ?!我没有代理，试图明确设置NoProxy没有运气。问题可能是什么？有什么想法吗？

重启Qt和创建者并重启帮助。
