如何获取IMSI号？

[vigoqiu]

我用下面代码获取IMSI号，返回-46，会是什么原因呢？

#include <Etel3rdParty.h>

class MImsiObserver
{
public:
// New methods
virtual void GotIMSIL(const TDesC& aIMSI, TInt aError) = 0;
};

class CImsiReader : public CActive
{

public:
static CImsiReader* NewL(MImsiObserver& aObserver);
static CImsiReader* NewLC(MImsiObserver& aObserver);
~CImsiReader();
protected:
void DoCancel();
void RunL();
private:
CImsiReader(MImsiObserver& aObserver);
void ConstructL(void);

public:
void StartReading(void);

private:
MImsiObserver& iObserver;
CTelephony* iTelephony;
CTelephony::TSubscriberIdV1 iImsiV1;
CTelephony::TSubscriberIdV1Pckg iImsiV1Pkg;
};










#include "ImsiReader.h"

CImsiReader* CImsiReader::NewL(MImsiObserver& aObserver)
{
CImsiReader* self = NewLC(aObserver);
CleanupStack::Pop(self);
return self;
}

CImsiReader* CImsiReader::NewLC(MImsiObserver& aObserver)
{
CImsiReader* self = new (ELeave) CImsiReader(aObserver);
CleanupStack::PushL(self);
self->ConstructL();
return self;
}

CImsiReader::CImsiReader(MImsiObserver& aObserver) :
CActive(0), iObserver(aObserver), iImsiV1Pkg(iImsiV1)
{
}

CImsiReader::~CImsiReader()
{
Cancel();
delete iTelephony;

}

void CImsiReader::ConstructL(void)
{
CActiveScheduler::Add(this);

iTelephony = CTelephony::NewL();
}
void CImsiReader::StartReading(void)
{
iTelephony->GetSubscriberId(iStatus, iImsiV1Pkg);
SetActive();
}

void CImsiReader::DoCancel()
{
iTelephony->CancelAsync(CTelephony::EGetSubscriberIdCancel);
}

void CImsiReader::RunL()
{
//LP: added ";" and replaced iTelephony with iObserver
iObserver.GotIMSIL(iImsiV1.iSubscriberId, iStatus.Int());
}






这代码我是在诺基亚论坛下下来的，很奇怪的是在那里下载的例子可以正常获取，我新建一个工程把代码移过来就取不到，什么都没动。代码在这：http://wiki.forum.nokia.com/index.php/Reading_IMSI_in_3rd_Edition

哪位大大给点意见吗？能力我都加上了

我参照里面的代码成功获取到imsi和imei

Hi,

-46是因为应用程序少能力，你试试加上ReadDeviceData能力看看能不能解决。

// e32err.h
...
/**
 System wide error code -46 : an operation cannot be performed due to
 a potential security violation. 
 A system wide error code indicates an error in the environment, or in
 user input from which a program may recover.
 */
const TInt KErrPermissionDenied=(-46);
...

如果你确认该加的能力都加到mmp里了但还是不行，那建议清一下整个工程，然后重新build。在用旧版本的Carbide.c++的时候我遇到过改了mmp但IDE不认的情况，但清一下工程就好了。
