Detailed Description

Minimal http connection support.

Most useful for connections to YARP ports from browsers. No support for connections in the opposite direction. This carrier is recruited when a port sees a TCP stream that begins with "GET /".

For "GET /", the URL following the "/" is currently translated to text as follows: ", " becomes newline "+" becomes " " This text is then passed on to the port, just as for a normal text connection. For example "GET /d, list" is the same as telnetting into a port and typing: CONNECT anon d list or typing "list" to "yarp rpc /portname". The response of the port, if any, is output in ugly html.

For "POST /" ... not done yet.

Member Function Documentation

◆ apply()

void yarp::os::impl::HttpTwoWayStream::apply ( char  ch)
virtual

Definition at line 401 of file HttpCarrier.cpp.

◆ beginPacket()

void yarp::os::impl::HttpTwoWayStream::beginPacket ( )
overridevirtual

Mark the beginning of a logical packet.

This is a unit that should be treated in an atomic fashion by YARP. If any part is corrupted, the whole should be dropped.

Implements yarp::os::TwoWayStream.

Definition at line 503 of file HttpCarrier.cpp.

◆ close()

void yarp::os::impl::HttpTwoWayStream::close ( )
overridevirtual

Terminate the stream.

Implements yarp::os::TwoWayStream.

Definition at line 496 of file HttpCarrier.cpp.

◆ endPacket()

void yarp::os::impl::HttpTwoWayStream::endPacket ( )
overridevirtual

Mark the end of a logical packet (see beginPacket).

Implements yarp::os::TwoWayStream.

Definition at line 508 of file HttpCarrier.cpp.

◆ finish()

void yarp::os::impl::HttpTwoWayStream::finish ( )

Definition at line 518 of file HttpCarrier.cpp.

◆ flip()

void yarp::os::impl::HttpTwoWayStream::flip ( )

Definition at line 513 of file HttpCarrier.cpp.

◆ getInputStream()

yarp::os::InputStream & yarp::os::impl::HttpTwoWayStream::getInputStream ( )
overridevirtual

Get an InputStream to read from.

Returns
the InputStream associated with this object.

Implements yarp::os::TwoWayStream.

Definition at line 360 of file HttpCarrier.cpp.

◆ getLocalAddress()

const Contact & yarp::os::impl::HttpTwoWayStream::getLocalAddress ( ) const
overridevirtual

Get the address of the local side of the stream.

Returns
the address of the local side of the stream. The address will be tagged as invalid if the stream is not set up.

Implements yarp::os::TwoWayStream.

Definition at line 370 of file HttpCarrier.cpp.

◆ getOutputStream()

yarp::os::OutputStream & yarp::os::impl::HttpTwoWayStream::getOutputStream ( )
overridevirtual

Get an OutputStream to write to.

Returns
the InputStream associated with this object.

Implements yarp::os::TwoWayStream.

Definition at line 365 of file HttpCarrier.cpp.

◆ getRemoteAddress()

const Contact & yarp::os::impl::HttpTwoWayStream::getRemoteAddress ( ) const
overridevirtual

Get the address of the remote side of the stream.

Returns
the address of the remote side of the stream. The address will be tagged as invalid if the stream is not set up.

Implements yarp::os::TwoWayStream.

Definition at line 375 of file HttpCarrier.cpp.

◆ isOk()

bool yarp::os::impl::HttpTwoWayStream::isOk ( ) const
overridevirtual

Check if the stream is ok or in an error state.

Returns
true iff the stream is ok

Implements yarp::os::TwoWayStream.

Definition at line 380 of file HttpCarrier.cpp.

◆ reset()

void yarp::os::impl::HttpTwoWayStream::reset ( )
overridevirtual

Reset the stream.

Implements yarp::os::TwoWayStream.

Definition at line 385 of file HttpCarrier.cpp.

◆ typeHint()

std::string * yarp::os::impl::HttpTwoWayStream::typeHint ( )

Definition at line 528 of file HttpCarrier.cpp.

◆ useJson()

bool yarp::os::impl::HttpTwoWayStream::useJson ( )

Definition at line 523 of file HttpCarrier.cpp.

◆ write()

void yarp::os::impl::HttpTwoWayStream::write ( const Bytes &  b)
overridevirtual

Write a block of bytes to the stream.

Parameters
bthe bytes to write

Implements yarp::os::OutputStream.
