介绍
在开发过程中，我们有时候需要获得接入点得网关信息，遗憾的是QT 没有提供这样的 函数，所以我们必须在通过SYMBIAN API 传入相应的接入点ID，来获得网关信息，实现代码如下：
具体实现
首先需要设置.PRO文件
LIBS += -lcmmanager
其次引入头文件
#include <cmmanager.h>
#include <cmconnectionmethoddef.h>
实现proxyL函数
void proxyL( int aIapId)
{
TBool usesProxy( EFalse );
RCmManager cm;
cm.OpenLC();
usesProxy = cm.GetConnectionMethodInfoBoolL( aIapId, CMManager::ECmProxyUsageEnabled );
TUint32 proxyServerPort = 0;
HBufC* proxyServerName = NULL;
if(usesProxy)
{
proxyServerPort = cm.GetConnectionMethodInfoIntL( aIapId, CMManager::ECmProxyPortNumber );
proxyServerName = cm.GetConnectionMethodInfoStringL( aIapId, CMManager::ECmProxyServerName );
}
if(!proxyServerName)
{
noproxy();
}
else
{
CleanupStack::PushL(proxyServerName);
QString proxyHostName("");
int len = proxyServerName->Length();
if(len > 0)
{
proxyHostName = QString((QChar*)proxyServerName->Ptr(), len);
}
if (proxyHostName.isEmpty())
{
noproxy();
}
else
{
m_isProxyUsed = true;
m_proxy.setType(QNetworkProxy::HttpProxy);
m_proxy.setHostName(proxyHostName);
m_proxy.setPort(proxyServerPort);
}
CleanupStack::PopAndDestroy( proxyServerName );
}
CleanupStack::PopAndDestroy(); // cm
qDebug() << "<< DownloadMgtServer::proxyL()";
}
实现noproxy函数
void noproxy(){
m_isProxyUsed = false;
m_proxy.setType(QNetworkProxy::NoProxy);
m_proxy.setHostName("");
m_proxy.setPort(0);
}最后在我们的应用中通过QNetWorkConfigutation得到接入点ID传入proxy 函数，并设置应用程序网关
QNetworkConfiguration config = session->configuration();
QString iapID = config.identifier()
if (iapId != "") {
if (iapId.startsWith("i_", Qt::CaseInsensitive)) {
iapId.remove(0, 2);
}
int identifier = iapId.toInt();
proxyL(identifier);
QNetworkProxy::setApplicationProxy(m_proxy);
