大多数 HTTP 通信是使用 Qt 中的 QNetworkRequest、QNetworkAccessManager 和 QNetworkReply 类完成的。要从 Web 服务获取响应，请遵循以下显示的代码段：

QNetworkAccessManager* netManager = new QNetworkAccessManager();
if (netManager) {

QUrl url(webServiceUrl);
QNetworkRequest req(url);

QNetworkReply* reply = netManager->get(req);
connect(reply, SIGNAL(finished()), this, SLOT(onReply()));
}

在 onReply 插槽中，您可以检查回复是否包含任何错误并解析响应。请注意，响应将采用 QByteArray 的形式，您可能需要转换为 QString 或您想要的形式。
