Hi, everyone, I want to upload a large file to server, and i use http post to upload, here is my code segment:
<code>
TInt CHttpXXX::SetHeader( )
{
if(iPostData==NULL)
{
iPostData = HBufC8::NewL(10000);
}
iStart = -1;

TPtr8 iPostDataPtr = iPostData->Des();
iPostDataPtr.Zero();
iPostDataPtr.Append(_L("--AaB03x"));
iPostDataPtr.Append(_L("\r\n"));
iPostDataPtr.Append(_L("Content-Disposition: form-data; name=\"name\""));
iPostDataPtr.Append(_L("\r\n\r\n"));
iPostDataPtr.Append(_L("xxxxxxxxxxxxxxxx"));
iPostDataPtr.Append(_L("\r\n"));

iPostDataPtr.Append(_L("--AaB03x"));
iPostDataPtr.Append(_L("\r\n"));
iPostDataPtr.Append(_L("Content-Disposition: form-data; name=\"password\""));
iPostDataPtr.Append(_L("\r\n\r\n"));

iPostDataPtr.Append(_L("yyyyyyyyyyyyyyyy"));
iPostDataPtr.Append(_L("\r\n"));

iPostDataPtr.Append(_L("--AaB03x"));
iPostDataPtr.Append(_L("\r\n"));
iPostDataPtr.Append(_L("Content-Disposition: form-data; name=\"file\"; filename=\"xxx.png\""));
iPostDataPtr.Append(_L("\r\n"));

iPostDataPtr.Append(_L("Content-Type: image/png"));
iPostDataPtr.Append(_L("\r\n\r\n"));

TInt fileSize = GetFileSize(_L("C:\\DATA\\hello.png")); // this function I wrote for geting the file's size

iDataLength = iPostDataPtr.Length() + fileSize;
TBuf<50> buf(0);
buf.Copy(_L("\r\n"));
buf.Append(_L("--AaB03x"));
buf.Append(_L("--"));

iDataLength += buf.Length();

return 0;
}

TBool CHttpXXX::GetNextDataPart(TPtrC8& aDataPart)
{
if(iStart == -1)
{
aDataPart.Set(iPostData->Des());
iDataAvailable = ETrue;
iStart = 0;
return EFalse;
}

TPtr8 ptr = iPostData->Des();
if(iStart<=GetFileSize(_L("C:\\DATA\\hello.png")))
{
ptr.Zero();
TBuf8<6000>* temp = new(ELeave) TBuf8<6000>(0);
CleanupStack::PushL(temp);
LoadPartFileDataToBuffer(_L("C:\\DATA\\hello.png"), *temp, iStart, 5*1024);// this function is used for load a part data of the file, the last two parms is stand for the start index and the length
ptr.Copy(*temp);
iStart += 5*1024;
aDataPart.Set(iPostData->Des());
iDataAvailable = ETrue;
iPartFinished = EFalse;
CleanupStack::PopAndDestroy(temp);
return EFalse;
}
else
{
ptr.Zero();
ptr.Copy(_L("\r\n"));
ptr.Append(_L("--AaB03x"));
ptr.Append(_L("--"));
aDataPart.Set(iPostData->Des());
iDataAvailable = EFalse;
return ETrue;
}

}

void CHttpXXX::ReleaseData()
{
if(iDataAvailable)
{
iTransaction.NotifyNewRequestBodyPartL();
}
}

TInt CHttpXXX::Reset()
{
return 0;
}

TInt CHttpXXX::OverallDataSize()
{
if(iPostData)
return iDataLength;
else
return KErrNotFound;

}

The code works on symbian 8.1a SDK, but just only work on emulator and can upload the file to the server can not work on 6680, when
I upload a file, the screen has no response. And in symbian9.1 SDK, it can not work on emulator and device, I
don't which part is wrong, can anybody help me? Thanks verymuch

it might help if you could explain a bit more on the problem, basically what gets executed and what doesn't, any error there, and so on..
