Member Function Documentation

void HTTP1xCodecCallback::onBody ( HTTPCodec::StreamID  stream, std::unique_ptr< folly::IOBuf >  chain, uint16_t  padding  )

inlineoverridevirtual

Called for each block of message body data

Parameters

stream	The stream ID
chain	One or more buffers of body data. The codec will remove any protocol framing, such as HTTP/1.1 chunk headers, from the buffers before calling this function.
padding	Number of pad bytes that came with the data segment

Implements proxygen::HTTPCodec::Callback.

Definition at line 37 of file HTTP1xCodecTest.cpp.

References folly::IOBuf::computeChainDataLength().

                                   {
    bodyLen += chain->computeChainDataLength();
  }

void HTTP1xCodecCallback::onChunkComplete ( HTTPCodec::StreamID  )

inlineoverridevirtual

Called when the terminating CRLF is received to end a chunk of HTTP body data.

Parameters

stream

The stream ID

Reimplemented from proxygen::HTTPCodec::Callback.

Definition at line 44 of file HTTP1xCodecTest.cpp.

{}

void HTTP1xCodecCallback::onChunkHeader ( HTTPCodec::StreamID  , size_t    )

inlineoverridevirtual

Called for each HTTP chunk header.

onChunkHeader() will be called when the chunk header is received. As the chunk data arrives, it will be passed to the callback normally with onBody() calls. Note that the chunk data may arrive in multiple onBody() calls: it is not guaranteed to arrive in a single onBody() call.

After the chunk data has been received and the terminating CRLF has been received, onChunkComplete() will be called.

Parameters

stream	The stream ID
length	The chunk length.

Reimplemented from proxygen::HTTPCodec::Callback.

Definition at line 42 of file HTTP1xCodecTest.cpp.

                                        {}

void HTTP1xCodecCallback::onError ( HTTPCodec::StreamID  stream, const HTTPException &  error, bool  newTxn  )

inlineoverridevirtual

Called when a parsing or protocol error has occurred

Parameters

stream	The stream ID
error	Description of the error
newTxn	true if onMessageBegin has not been called for txn

Implements proxygen::HTTPCodec::Callback.

Definition at line 51 of file HTTP1xCodecTest.cpp.

                                {
    ++errors;
    LOG(ERROR) << "parse error";
  }

void HTTP1xCodecCallback::onHeadersComplete ( HTTPCodec::StreamID  stream, std::unique_ptr< HTTPMessage >  msg  )

inlineoverridevirtual

Called when all the headers of an ingress message have been parsed

Parameters

stream	The stream ID
msg	The message
size	Size of the ingress header

Implements proxygen::HTTPCodec::Callback.

    headersComplete++;
    headerSize = msg->getIngressHeaderSize();
    msg_ = std::move(msg);
  }

void HTTP1xCodecCallback::onMessageBegin ( HTTPCodec::StreamID  stream, HTTPMessage *  msg  )

inlineoverridevirtual

Called when a new message is seen while parsing the ingress

Parameters

stream	The stream ID
msg	A newly allocated HTTPMessage

Implements proxygen::HTTPCodec::Callback.

                                               {}

void HTTP1xCodecCallback::onMessageComplete ( HTTPCodec::StreamID  stream, bool  upgrade  )

inlineoverridevirtual

Called at end of a message (including body and trailers, if applicable)

Parameters

stream	The stream ID
upgrade	Whether the connection has been upgraded to another protocol.

Implements proxygen::HTTPCodec::Callback.

Definition at line 47 of file HTTP1xCodecTest.cpp.

                                          {

  }

void HTTP1xCodecCallback::onPushMessageBegin ( HTTPCodec::StreamID  , HTTPCodec::StreamID  , HTTPMessage *    )

inlineoverridevirtual

Called when a new push message is seen while parsing the ingress.

Parameters

stream	The stream ID
assocStream	The stream ID of the associated stream, which can never be 0
msg	A newly allocated HTTPMessage

Reimplemented from proxygen::HTTPCodec::Callback.

Definition at line 28 of file HTTP1xCodecTest.cpp.

                                                   {}

void HTTP1xCodecCallback::onTrailersComplete ( HTTPCodec::StreamID  stream, std::unique_ptr< HTTPHeaders >  trailers  )

inlineoverridevirtual

Called when all the trailers of an ingress message have been parsed, but only if the number of trailers is nonzero.

Parameters

stream	The stream ID
trailers	The message trailers
