QT：轻松获取网页源码

获取网页源码的小例子，代码很简单，就不多作解释了。

[cpp]
#include  
#include  
 
//网页地址 
const QString URLSTR = ""; 
//储存网页代码的文件 
const QString FILE_NAME = "code.txt"; 
 
int main(int argc, char **argv) 
{ 
    QCoreApplication app(argc, argv); 
    QUrl url(URLSTR); 
    QNetworkAccessManager manager; 
    QEventLoop loop; 
    qDebug() << "Reading code form " << URLSTR; 
    //发出请求 
    QNetworkReply *reply = manager.get(QNetworkRequest(url)); 
    //请求结束并完成后，退出子事件循环 
    QObject::connect(reply, SIGNAL(finished()), &loop, SLOT(quit())); 
    //开启子事件循环 
    loop.exec(); 
 
    //将读到的信息写入文件 
    QString code = reply->readAll(); 
    QFile file(FILE_NAME); 
    file.open(QIODevice::WriteOnly); 
    QTextStream out(&file); 
    out << code << endl; 
    file.close(); 
    qDebug() << "Finished, the code have written to " << FILE_NAME; 
    return 0; 
}
