回復(fù) 1# send_linux
前段時(shí)間想通過(guò)HTTP來(lái)上傳文件，發(fā)生了一件奇葩事，，哈哈。。不多說(shuō)直接上代碼：
void COSBHTTPClient::UploadFile( TOSBDownloadParam& aParam, TDesC8& aContentType )
//aContentType = “multipart/form-data; boundary=AaB03x”
{
iClient->CancelTransaction();
RFile rFile;
RFs fs;
if( KErrNone != fs.Connect() )
{
return;
}
//Open file where the stream text is
TInt error = rFile.Open( fs, iDownloadParam->iFileName, EFileShareAny );//EFileRead );
CleanupClosePushL( rFile );
TInt size = -1;
User::LeaveIfError( rFile.Size( size ) );
HBufC8* aXmlBuffer = HBufC8::NewLC( size );
TPtr8 bufPtr( aXmlBuffer->Des() );
error = rFile.Read( bufPtr );
CleanupStack: op( aXmlBuffer ); // aXmlBuffer
CleanupStack:opAndDestroy( &rFile ); // rFile
fs.Close();
_LIT8(KDataStart,"--AaB03x" ;
_LIT8(KCrlf,"\r\n";
_LIT8(KContent,"Content-Disposition: form-data; name='userfile'; filename='";
_LIT8(KFileCompletion,"'";
_LIT8(KContent2,"Content-Type: text/plain";
_LIT8(KContent3,"Content-Transfer-Encoding: binary";
_LIT8(KDataEnd,"--AaB03x--";
HBufC8* iPostData = HBufC8::NewL( 650+ size );
TPtr8 iPostDataPtr = iPostData->Des();
iPostDataPtr.Zero();
iPostDataPtr.Append(KCrlf);
iPostDataPtr.Append(KDataStart);
iPostDataPtr.Append(KCrlf);
iPostDataPtr.Append(KContent);
// iPostDataPtr.Append(aFname);
iPostDataPtr.Append(KFileCompletion);
iPostDataPtr.Append(KCrlf);
iPostDataPtr.Append(KContent2);
iPostDataPtr.Append(KCrlf);
iPostDataPtr.Append(KContent3);
iPostDataPtr.Append(KCrlf);
iPostDataPtr.Append(KCrlf);
iPostDataPtr.Append(bufPtr); //the file in binary
iPostDataPtr.Append(KCrlf);
iPostDataPtr.Append(KDataEnd);
iPostDataPtr.Append(KCrlf);
iClient->IssueHTTPPostL(URL, aContentType, iPostDataPtr);
iObserver.ClientEvent( MOSBHTTPClientObserver::EEventConnecting );
}
復(fù)制代碼void CClientEngine::IssueHTTPPostL( const TDesC8& aUri,
const TDesC8& aContentType, const TDesC8& aBody )
{
SetupConnectionL();
// Parse string to URI
TUriParser8 uri;
TInt ret = uri.Parse( aUri );
// Copy data to be posted into member variable; iPostData is used later in
// methods inherited from MHTTPDataSupplier.
delete iPostData;
iPostData = aBody.AllocL();
// Get request method string for HTTP POST
RStringF method = iSession.StringPool().StringF(HTTP::EPOST, RHTTPSession::GetTable());
// Open transaction with previous method and parsed uri. This class will
// receive transaction events in MHFRunL and MHFRunError.
iTransaction = iSession.OpenTransactionL( uri, *this, method );
// Set headers for request; user agent, accepted content type and body's
// content type.
RHTTPHeaders hdr = iTransaction.Request().GetHeaderCollection();
SetHeaderL( hdr, HTTP::EUserAgent, KUserAgent );
SetHeaderL( hdr, HTTP::EAccept, KAccept );
SetHeaderL( hdr, HTTP::EContentType, aContentType );
// Set this class as an data supplier. Inherited MHTTPDataSupplier methods
// are called when framework needs to send body data.
MHTTPDataSupplier* dataSupplier = this;
iTransaction.Request().SetBody( *dataSupplier );
// Submit the transaction. After this the framework will give transaction
// events via MHFRunL and MHFRunError.
iTransaction.SubmitL();
}
復(fù)制代碼void CClientEngine::MHFRunL( RHTTPTransaction aTransaction,
const THTTPEvent& aEvent )
{
}
復(fù)制代碼現(xiàn)在與服務(wù)器的連接可以成功，但是body總是傳不上去，從log看MHFRunL的aEvent，走了下面3種狀態(tài)
THTTPEvent::EGotResponseHeaders
THTTPEvent::EResponseComplete
THTTPEvent::ESucceeded
可是THTTPEvent::EGotResponseBodyData始終沒(méi)有走到，自己總是以為上傳失敗，苦苦糾結(jié)了一個(gè)下午，，，最后才發(fā)現(xiàn)我是POST，不走THTTPEvent::EGotResponseBodyData，除非在POST給服務(wù)器的時(shí)候服務(wù)器還有返回信息才會(huì)走。。。。
