c++ - 没有完成信号的 QNetworkAccessManager

Question

我想直接请求和响应，而不是使用 connect(..,SLOT(finished()),..,SLOT())

Answer 1

您可以使用QEventLoop，以便应用程序等待并可以同时处理其他事件。

#include <QCoreApplication>
#include <QNetworkAccessManager>
#include <QNetworkReply>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QNetworkAccessManager *manager = new QNetworkAccessManager;
    QEventLoop loop;
    QObject::connect(manager, &QNetworkAccessManager::finished, &loop, &QEventLoop::quit);
    QNetworkReply *reply = manager->get(QNetworkRequest(QUrl("https://api.github.com/events")));
    loop.exec();

    qDebug()<<reply->readAll();

    delete reply;
    delete manager;

    return 0;
}
