我有一些非常奇怪的东西我有这个代码:
我想我知道出了什么问题,但我不知道如何解决它。这就是我所拥有的:当我在 int test = 0 中放置断点时;它在到达 HttpClient 中的 httpFinished() 插槽之前到达那里,这就是问题所在吗?在 main.cpp
---------------------------------------------------------------------------------------------------------
@while (i.hasNext())
{
i.next();
ThreadWorker* pThreadWorker = new ThreadWorker();
pThreadWorker->setUrl(sUrl);
QThreadPool::globalInstance()->start(pThreadWorker);
}
QThreadPool::globalInstance()->waitForDone();
---------------------------------------------------------------------------------------------------------
void ThreadWorker::run()
{
startWork();
}
void ThreadWorker::startWork()
{
m_pHttpClient = new HttpClient();
m_pHttpClient->startRequest(m_url);
int test = 0;
}
--------------------------------- HttpClient based on the http example from Qt -----------------------------------
HttpClient::HttpClient()
{
m_networkManager = new QNetworkAccessManager(this);
connect(m_networkManager, SIGNAL(authenticationRequired(QNetworkReply*,QAuthenticator*)),
this, SLOT(slotAuthenticationRequired(QNetworkReply*,QAuthenticator*)));
#ifndef QT_NO_OPENSSL
connect(m_networkManager, SIGNAL(sslErrors(QNetworkReply*,QList<QSslError>)),
this, SLOT(sslErrors(QNetworkReply*,QList<QSslError>)));
#endif
}
void HttpClient::startRequest(QUrl url)
{
m_url.setUrl("http://qt.nokia.com/");
QNetworkRequest request;
request.setUrl(m_url);
reply = m_networkManager->get(request);
connect(reply, SIGNAL(error(QNetworkReply::NetworkError)),
this, SLOT(slotError(QNetworkReply::NetworkError)));
connect(reply,SIGNAL(finished()),
this, SLOT(httpFinished()));
connect(reply, SIGNAL(readyRead()),
this, SLOT(httpReadyRead()));
connect(reply, SIGNAL(downloadProgress(qint64,qint64)),
this, SLOT(updateDataReadProgress(qint64,qint64)));
}
私有插槽下的 httpFinished() 函数:从未触发,为什么?
