Qt - 从网址下载数据

Question

我用PHP编写了一个Web服务.我需要通过Web服务URL下载内容.如何从URL下载数据？

需要哪些库？

Answer 1

1. 添加QT += network.pro项目文件

2. 在您的代码中包含以下库:

   #include <QUrl>
   #include <QtNetwork/QNetworkAccessManager>
   #include <QtNetwork/QNetworkRequest>
   #include <QtNetwork/QNetworkReply>
   

3. 最后通过以下代码接收URL内容:

   QString url = "WEB_SERVICE_URL";
   QNetworkAccessManager manager;
   QNetworkReply *response = manager.get(QNetworkRequest(QUrl(url)));
   QEventLoop event;
   connect(response, SIGNAL(finished()), &event, SLOT(quit()));
   event.exec();
   QString content = response->readAll();
