Qt request获取百度界面（最简单的例子）

一、工程文件Pro中添加  QT += network

#include <QNetworkAccessManager>
#include <QNetworkRequest>
#include <QNetworkReply>

int main()
{

 QNetworkRequest request;
 request.setUrl(QUrl("http://www.baidu.com"));
 QNetworkAccessManager manager;
 QNetworkReply *reply= manager.get(request);

 QObject::connect(&manager,&QNetworkAccessManager::finished,[=]{
 qDebug()<<"data"<<reply->readAll();}

 return 0;

}
