Even for QNetworkAccessManager, you should take a look at this signal:

Hi mgoetz:
I read the article you remended,then I tried ,but still failed,I dont know why,here is the codes,can you kindly give me some suggestions or solutions for proxy(password + username) writted with QNetworkAccessManager?
Thx a lot!
here is the code:
[
QNetworkAccessManager* qnam = new QNetworkAccessManager(this);

connect(qnam, SIGNAL(proxyAuthenticationRequired(const QNetworkProxy&, QAuthenticator*)), this,
SIGNAL(proxyAuthenticationRequired(const QNetworkProxy&, QAuthenticator*)));

QNetworkProxy proxy;
proxy.setType(QNetworkProxy::HttpProxy);
proxy.setHostName(pProxyInfo->qstrProxyServerName);
proxy.setPort(pProxyInfo->qstrProxyPort.toInt());
proxy.setUser(pProxyInfo->qstrProxyUserName);
proxy.setPassword(pProxyInfo->qstrProxyPassWord);

qnam->setProxy(proxy);

[mgoetz]

Yes
You should read about Qt signals and slots. I think you need a slot that sets the authentication parameters.

Add slot and response Func:reponseRecue,but stiil failed ,why???,It seems that i cant get the response message,bcz reponseRecue,not entered,and the dialogue says:detecting...
why???

[
QNetworkAccessManager* qnam = new QNetworkAccessManager(this);


connect(qnam, SIGNAL(finished(QNetworkReply *)), this, SLOT(reponseRecue(QNetworkReply*)));

connect(qnam, SIGNAL(authenticationRequired(QNetworkReply*,QAuth enticator*)),
this, SLOT(authenticate(QNetworkReply*,QAuthenticator*)) );

connect(qnam, SIGNAL(proxyAuthenticationRequired(const QNetworkProxy&, QAuthenticator*)),
this, SLOT(proxyAuthenticationRequired(const QNetworkProxy&, QAuthenticator*)));

//begin mod
QNetworkProxy proxy;
proxy.setType(QNetworkProxy::HttpProxy);
/*proxy.setType(QNetworkProxy::Socks5Proxy);*/
proxy.setHostName(pProxyInfo->qstrProxyServerName);
proxy.setPort(pProxyInfo->qstrProxyPort.toInt());
proxy.setUser(pProxyInfo->qstrProxyUserName);
proxy.setPassword(pProxyInfo->qstrProxyPassWord);
//QNetworkProxy::setApplicationProxy(proxy);*/

/*m_pTestHttpObj->setProxy(proxy);*/
qnam->setProxy(proxy);


....
....
void XXX::reponseRecue(QNetworkReply* reply)
{
CDlgSetting* pSet = (CDlgSetting*)m_pSet;
if (reply->error() == QNetworkReply::NoError)
{
pSet->OnCheckNetConnectSuccess();
qDebug() << reply->readAll();
QMessageBox::information(0, tr("Connection"), tr("ok"));
}
else
{
pSet->OnCheckNetConnectFaild();

QMessageBox::information(0, tr("Connection"), tr("Err !"));
}

m_pSet = NULL;
delete reply;
}

Please look into demos/browser/networkaccessmanager.cpp in the Qt source to see how proxyAuthenticationRequired is used there.
