Qt 的QNetworkAccessManager 出问题了

[jdgdf566]

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

#include <QCoreApplication>
#include <QString>
#include <QDebug>

class NetworkTest:public QObject {
    Q_OBJECT
public:

    void run() {
        //QNetworkRequest * request = new QNetworkRequest();
        //QNetworkReply * reply = new QNetworkReply();
        QNetworkAccessManager * manager = new QNetworkAccessManager(this);
        QNetworkReply * reply;
        QUrl url("http://www.forum.nokia.wiki");
        QNetworkRequest req;
        req.setUrl(url);

        QObject::connect( manager, manager->finished, this->finishedSlot );


        reply = manager->get(req);
    }


    //public Q_SLOTS:
    void finishedSlot(QNetworkReply * reply) {
        qDebug() << reply->readAll() <<endl;
    }


};


int main(int argc, char *argv[]) {
    QCoreApplication a(argc, argv);

    NetworkTest * net = new NetworkTest();
    net->run();

    return a.exec();
}

第23行：错误:no matching function for call to 'NetworkTest::connect(QNetworkAccessManager*&, <unresolved overloaded function type>, <unresolved overloaded function type>)'
第23行改成：

        connect(manager, SIGNAL(finished(QNetworkReply*)),this,SLOT(finishedSlot(QNetworkReply*)));

之后，错误变成：

楼主的问题太深奥了，呵呵，我也是新手，没办法帮你，我也是来求助的哈哈。 各位大虾们，求助一个紧急问题： 我是在PC端程序中使用QNetworkAccessManager实现HTTP的数据请求，发送请求的过程中(数据请求还没有完成)，断网比较容易高概率出现程序死机。xp上不会出现，在win7(VISTA)系统上出现的概率很高，不知道是QT本身的Bug还是我的代码问题，我实现的代码如下： ////////拨上号时 m_pHttp = new QNetworkAccessManager(); connect(m_pHttp, SIGNAL(finished(QNetworkReply*)), this, SLOT(onHttpFinished(QNetworkReply*)))； QUrl url(strHtpPath); QNetworkRequest request = QNetworkRequest(url); m_request = request; m_pHttp->get(request); ///接受数据完成时 void onHttpFinished(QNetworkReply* reply) { if(reply->error() == QNetworkReply::NoError) { QByteArray byteAllRead = reply->readAll(); reply->close(); reply->deleteLater(); } ////断网时 if(m_pHttp != NULL) { m_pHttp->setNetworkAccessible(QNetworkAccessManager::NotAccessible); m_pHttp->deleteResource(m_request); disconnect(m_pHttp, SIGNAL(finished(QNetworkReply*)), this, SLOT(onHttpFinished(QNetworkReply*))); m_pHttp->deleteLater(); m_pHttp = NULL; } 我是直接在GUI的主线程中做的，而且我没有开辟新的线程，我测试了一下，发现QWebView在win7(Vista)系统上，发送请求的过称中，断网也会出现程序死机。大家之前遇到过类似的问题吗？我感觉像是QT本身的BUg,我使用的是QT4.7的版本，大家帮忙分析一下，谢谢！！！ ________________________________________ use c#.net qrcode creator to create qrcode in c#.net
