在QT中如何将网络图片保存到本地
1 void saveImage(const QString url)
2 {
3 QNetworkRequest request(url);
4 QNetworkAccessManager *networkManager = new QNetworkAccessManager();
5 QNetworkReply *reply = networkManager->get(request);
6 QEventLoop eventLoop;
7 QObject::connect(reply, SIGNAL(finished()), &eventLoop, SLOT(quit()));
8 eventLoop.exec();
9 if(reply->error() == QNetworkReply::NoError)
10 {
11 auto data = reply->readAll();
12 auto image = QImage::fromData(data);
13 image.save("E:/test.png");
14 }
15 else
16 {
17 qDebug() << reply->errorString();
18 }
19 }
说明：第12,13行通过QImage保存图片数据，也可通过QFile来实现。
