Accessing the data in a HTTP filter

[aquarian3183]

Hi,

I wanted to access the body of a HTTP request and I see in the documentation that an filter provides an handle to MHTTPDataSupplier class through which the data of a request can be retrieved, but I am not aware as to how I can access this data supplier to retrieve the information of this data supplier.If i try to use the following code, it gives a EUser CBase 42 panic, which says that there is already an active object running(meaning there is a data supplier already present)

iDataSupplier = aTransaction.Request().Body();
iDataSupplier->GetNextDataPart(Ptr);

Can anyone please let me know how to access the datasupplier provided by the filter.

Hi,

I tried to access the body of a HTTP request, i.e the data being posted during a file upload as i have to start an application depending on the content type of the multipart data being uploaded, I am trying to omplement this funcationality in a filter but i am getting a panic unable to perform the opeartion -26000.

I am using getnextdatapart of the MHTTPDataSupplier class in the submit event of the filter, actually it is blocking the whole uploading event.

Here is the chunk of code :

case THTTPEvent::ESubmit:
{

RHTTPRequest aRequest;
MHTTPDataSupplier* iDataSupplier;


TBool HasBody = aTransaction.Request().HasBody();
if(HasBody==1)
{

iDataSupplier = aTransaction.Request().Body();
TPtrC8 ptr;
TBool isLast = iDataSupplier->GetNextDataPart(ptr);
if(isLast==EFalse)
{
iDataSupplier->ReleaseData();
}

Display();
}

}
break;

Kindly let me know how do we get to know the content type of the data being uploaded through a filter.

Regards.

at least if(HasBody==1) is not gonna be true too often, since ETrue != EFalse, and EFalse != 0, which means that ETrue can be any other value than 0 actually.

Hi SymbianYucca,

Actually all submit events do not have body to check this condition I am using this but the line iDataSupplier->GetNextDataPart(ptr) is giving problem, can u please let me know what might be causing problem.

Looking forward for suggestion on the same.

Regards!
